Our 2002 Sebring Coupe with 6cyl- 3.0 engine suddenly accelerated while
backing up in a parking lot causing a wreck. It lurched backward at top
speed. Has anyone heard of this happening?

Yes, it happened with several Audi's many years ago.  The cause then was
likely the same as the cause with your Sebring ... the driving
mistakenly mashing the throttle thinking they are hitting the brake.

Nope i didn't happen that way. My wife was backing up with her foot on
the brake. She must not have been braking that hard.. but she says she
had her foot on the brake pedal and when shifting forward on the shift
lever into drive & past neutral is when it SUDDENLY jumped backward and
fast. She then smashed on the brake pedal at the same time she crunched
into another car.

I haven't driven a Sebring, but all floor mounted automatics that I've
driven have P-R-N-D-2-1 with Park at the front (towards the dash).  So,
if your wife was backing up, that suggests she was in reverse.  If she
moved the parking lever forward from there, she would have engaged park
not drive or neutral.  If the shifter is column mounted, then it is
moving left/right or up/down, not forward/back.  Something isn't jiving
with this story.

Nope, it didn't happen that way. Your wife hit the gas without knowing it,
period. I know it's less embarrassing and less expensive for her to blame
it on the car, but cars do not behave so much as they are behaved upon.

If you want to make any kind of a legal case, you will have a major uphill
battle. As others have stated, the AVN ("Audi Victims Network") legal
campaign went down in flames when multiple and overwhelming sources of
evidence showed to everyone (including consumer organizations) that driver
error was at fault. Drivers inevitably swore they did not commit pedal
error, even when it was conclusively demonstrated they had. Additionally, a
high proportion of the drivers involved were either menopause-age women or
seniors of both sexes.

Please don't take this as a challenge to your (or your wife's) honesty,
merely a "heads-up" about the historical background.

Yes, I don't think it is an honesty issue.  I believe that many, if not
all, of the Audi drivers really believed that they were mashing the
brake, when they were, unfortunately, mashing the throttle.  And this
gentleman's wife very likely also believed that as well.  However, that
still doesn't change the fact that it is about 99.44% certain that she
hit the throttle by mistake, especially if she was twisted around
looking backwards when backing up.

Nomen Nescio - 22 Jan 2005 03:00 GMT
Back in the good old days, sometimes the gas pedal linkage would bind or
the return spring pop off.  Get a good independent mechanic to inspect the
mechanical control to the throttle body.

Big air leaks will also cause this effect.  Possible a large diameter
vacuum hose popped loose.

You have no idea how dangerous today's cars are.  If the vacuum hose to the
brake booster pops off, you will crash before you realize what happened.

If a fuel line pops off at the fuel injector rail, the fire resulting will
cremate your entire car.

That is why cars need FAA certification; not because they cannot fly.  In
the meantime, pay $50,000 for a car full of things that can pop off.

Yes.  This happened to Audi's a while back.  The government did a lot of
reasearch.  In all instances the brake system was still functioning
properly.  In all instances the drivers states they were stepping on the
brakes as hard as they could and the car kept going.  The government came
to the conclusion that this was a case of pedal mis-application.  That
means that driver was stepping on the wrong pedal.  I don't think that
is what you wanted to hear.

Nobody wants to hear that, but that is the fact.  Also, there are very
few cars that have an engine that can overpower the brakes.  And you'd
likely need AWD as in FWD or RWD, two wheels locked will keep the other
two wheels from moving the car at any rate of speed in any event.  When
I first heard the Audi stories years ago, I knew they were bogus without
even doing an investigation.  Simple physics showed that you couldn't
possibly have a car that couldn't be controlled using the brakes at full
application.  Of course, if there had been a defect in the brakes, then
the claims would have been plausible, but that was never found to be the
case in any of the cars.

Nobody wants to hear that the problem was them, but that is usually the
case in these sudden acceleration cases.  I'm not saying there isn't the
potential for this to happen, as anything is certainly possible.  It is
possible that the brakes could fail at the exact same time that a
software bug in the ECU commanded full throttle, but that is a long shot
beyond long shots.

 Just curious, but if it was suspected to be merely a case of pedal
mis-application, why was this situation peculiar only to Audi's and not
all models?
 I would also be curious as to how many instances of the above

It was not unique to Audi, a number of manufacturers were being accused of
Sudden Acceleration, Audi was just the most notorious.  Studies revealed
that the position of the gas and brake pedals were closer together than the
driver was used to and that the driver, in attempting to step on the brakes,
was stepping on the gas instead.  At that point denial set in, "Of course, I
didn't step on the gas, the car just went out of control by itself."

And yes, the problem lay with cars with automatic transmissions.  There was
an organization that was able to "replicate" a case of unintended
acceleration, I don't remember if it was a news agency or a victims advocacy
group.  It required overriding so many safety interchecks, including a
number of valves in the transmission that it was realized that such an event
was so highly improbable that it verged on impossible.

It's been a long time and I honestly don't remember the details, but
I'll bet if you search around a while you might find something ...
although I think much of this was pre internet.  I believe the
predominant theory was that the pedals in the Audi were closer together
than in many other cars and offset farther to the right relative to the
driver.  This may have contributed to the pedal misapplication.

I did a number of investigations on Chevrolet Astro vans in the
mid 80s when I worked in a Chevy dealership, the Astro and Safari
have a fairly narrow drivers foot well and the throttle and brake
pedals are quite close together.  I remember one van was owned by
a TV station but they never did a news segment on it claiming it
was a defect.

IIRC, all the Audi cases were automatic.

Yep. The factory "fix" for stupid drivers was a brake/shift interlock and
an insert plate for the shift quadrant that said "DEPRESS BRAKE TO SHIFT
FROM PARK".
Bob Shuman - 24 Jan 2005 14:34 GMT
I have read the majority of the responses you received and tend to agree
that the simplest explanation is application of the wrong pedal.  That said,
I had an experience that I do not believe anyone else has related and this
could also have been a cause for the accident so I'll describe what happened
to me here in a completely different vehicle.

I was accelerating down an on ramp to an expressway and merging with the
flow in a 1991 Mitsubishi 3000GT.  I pushed the pedal to the floor and
quickly found myself at 65MPH and accelerating even though I had taken my
foot off the pedal.  IN another couple seconds I was over 90MPH and still
climbing!  I thought about my options: shut down the ignition, apply the
brakes, reduce gears, etc. but all had possible undesirable results.  I
decided to reach down and check the accelerator and found that my carpet
floor mat had managed to get up under the accelerator so was holding it
down.  I pulled it free and the vehicle came back under control.

It was a harrowing experience and the split instant when I realized that the
vehicle had a mind of its own is what I'm certain that your wife
experienced.  As I indicated above, the most likely cause was driver error,
but a misplaced floormat  is another possibility so thought I would share my
story here.

I remember one of my high school teachers who had been a police officer
grabbing a couple of us and chewing us out in the parking lot one day.
He'd seen a friend of mine stuff his stack of books under the driver's
seat, and he said "what do you think would happen if a book slid forward
and got wedged under your brake pedal?" and then told a story of how a
flashlight had come loose and gotten under the brake pedal of a squad
car one time resulting in a nasty wreck. Ever since then (and that was
25 years ago), I've been REALLY careful about the kind of mats I use,
and careful to never stow *anything* under the driver's seat.

Same goes for the very badly named "package shelf" behind the rear seat.
I'm amazed at the bulky, heavy stuff people crap up the shelf with. Stop
short, and everything on the shelf flies forward like a missile.

Back in my days as a service writer I drove hundreds of customer's cars.
Usually about once a week, something weird would happen.  The throttle
sticking open happened twice.  The first time, I just cut the ignition,
no sweat.  The second time I stopped it with the brakes.  That was a
little unnerving, since you don't expect a car to start accelerating
again when you modulate brake pressure as normal, but it worked fine.
Both of these occasions were separate, in V8-powered cars.  The brakes
are easily more powerful than the engine in all but the most poorly
maintained systems.

Under no circumstances would I divert my eyes from the road with
something like that going on.

One of the first things you should always do is put your toe under the
gas pedal and try to lift it back up.  If that doesn't work, hit the
brakes and wait for the car to stop.

 Good point; I too have had the accelerator pedal become held down
after flooring it due to a displaced/crumpled floormat.
 I bet many people have experienced this at one time or another.
 It is noteworthy, however, that the cause of the problem in this case
is usually very obvious after it happened.

When the government did their investigation they found that most of the
people who had this problem were new to Audi ownership and have prviously
owned an American made car.  They also found that the space between the
brake and the gas was smaller on Audi's than on your typical American car.

Every model of every car has some incidence rate of "sudden acceleration".
After all, we're all human. After Audi installed a brake/shifter interlock,
that was the end of it for the 5000. Nobody ever really implicated the
5000's pedal arrangement. So it appears the only variable was the people who
owned Audi 5000's were more likely to blame somebody else for their mistake.

To believe that anything mechanical actually happened in that case is to
ignore all the evidence.

So, if sudden acceleration happens for real, and you're too ignorant of your
car to understand what went wrong, then there's nothing you can do. You
can't explain what happened to anybody. What I mean is, if your throttle
sticks, you need to say "my throttle stuck" instead of "I suffered sudden
acceleration due to the negligence of a large corporation" so everybody
won't dismiss you as an idiot. Your throttle is pretty simple. If it moves,
you'll have to figure out why.

If you can't do that, just turn the switch off like you're supposed to and
deal with the shame in private.

I firmly believe that virtually 100% of the cases of "unintended
acceleration" in cars made prior to about 2001 were because of driver
error. There's simply NO way that an engine with a mechanical throttle
linkage can accelerate unless the return spring breaks, and it doesn't
"go back to normal" immediately thereafter- it stays broken.

Howver, in recent years more cars are being built with "throttle by
wire" in which a computer-controlled servo moves the throttle blades,
not a direct mechanical linkage to the accelerator pedal. I know that
the systems and software go through tremendous testing, but I no longer
feel confident in saying that it "cannot happen" anymore.

Which begs the question...why make a very simple and reliable system more
complicated (with all the associated problems that more complicated systems
have)?

Yep- the throttle body location can be anywhere and you still use the
same accelerator pedal and the same throttle servo. No custom cable lengths.

>and supposed to be   a faster response for acceleration

And the sick and twisted irony is that "throttle by wire" engines are
NOTORIOUS for having a sluggish throttle response compared to direct
cables. The software always optimizes the throttle opening rate to
minimize fuel consumption and emissions, rather than letting you bang
the butterflies open instantly the way you can when your right foot is
firmly cabled to the throttle blades. That is the NUMBER ONE gripe I
hear from Ram truck owners who have compared the new 5.7 Hemi to the old
5.9 360. Yes, the Hemi has more horsepower and torque, but the old 5.9
slams you back harder and quicker when you first punch it because it
responds instantly. I've also observed the same thing when comparing an
older cable-throttle 3.5L v6 to the newest throttle-by-wire 3.5L v6.

The fuel injection on current mechanically operated throttle bodies is
controlled by the computer.  I don't see how controlling the butterfly
is inherently any slower than controlling the fuel.  And you need both
fuel and air to get the engine to respond.

Not true at all. If you slam the throttle open, the computer HAS to
respond with fuel at the same rate or the engine will backfire and
stall. It cannot "slow down" fuel delivery if you force an increase in
air delivery without leaning out the engine to the point that it would
backfire, stall, or at least detonate badly. So as long as the foot
connects directly to the butterfly valve, the operator can  demand
instant power and will get it.

With full-up TBW on the other hand, the computer has complete authority
to open the throttle no faster than the software design allows, and that
"allowance" can include all sorts of factors to mitigate emissions and
increase economy to bump the CAFE numbers up. Maybe your foot hits the
floor in 250 milliseconds, but the computer can insist that the throttle
not reach wide-open for 1.5 seconds if it wants to.

And thats exactly what people are saying about the 5.7 Hemi versus the
old 5.9.

Read again what I wrote.  I didn't say that the current hemi
implementation wasn't slower on throttle response, I simply said this
doesn't have to be the case.  That is, the design isn't INHERENTLY
slower.  The designers may choose to be slower, but that isn't an issue
with the technology, that is an issue with the designers.

The way I read the comment was such that it implied that conventional
throttling COULD be made to respond slower also. It can't. What threw me
off was  your statement "I don't see how controlling the
butterfly is inherently any slower than controlling the fuel"  since the
driver *never* directly controls the fuel in anything except a diesel.
Even with a carburetor, the driver controls the *air* and the fuel is
added in response- same with EFI and a cable throttle. Only a (non
computerized) diesel gives the driver direct control over fuel flow. So
it seemed to me that you were saying that since the computer still
controls fuel in a cable-throttle system, it can can slow the engine
response independently of the driver's foot on the throttle.

Wtih a carburetor the driver does control fuel on acceleration.

Of course, but you're missing the point that if they were going to open the
throttle when you wanted to, they wouldn't need throttle by wire. That's
what it's for, to allow the engine to respond in a more orderly (slower)
way.

I doubt that, I think it's for slower acceleration. If they put "throttle
response" in the hands of the computer, it can respond whenever it wants to.
At least that's the feeling I get when I drive one. If the computer decides
to downshift, it can wait before it actually opens the throttle.

This has got to be much easier for engine management. Cheaper? No. That's
just stupid, to think a motor-driven throttle is cheaper than a cable.

One motor-driven throttle that can be used on EVERY engine in EVERY car
made by the company is cheaper to produce than a different throttle
cable  for every engine/chassis combination. Not case-by-case, but in
terms of mass production.

As far as slowing down acceleration- that's mostly (my guess) to control
emissions and boost fuel economy. The real software benefit of TBW is
that the computer can cut the throttle whenever the automatic
transmission shifts, which allows the transmissions to be built even
lighter and cheaper than they already are because now the computer can
guarantee that there's no such thing as a "wide open throttle upshift,"
which transmissions used to have to be able to handle.

Yes, that is true.  Even cars with a mechanical POSSIBLY could do this
if they have cruise control as it can also control the throttle.
However, as has been pointed out already, it would take several
simultaneously component failures for this to happen.  Not impossible,
but certainly highly improbable.

I don't know anything about the design of drive-by-wire systems, but
fly-by-wire airplanes have thus far proven as safe as their predecessors
with mechanical controls.  As a former software engineer, however, I
admit to being more nervous on a fly-by-wire airplane than on a
conventionally controlled one.  :-)

To Road&Track's credit, they  took an Audi and tried it.  The result
was a driver that was convinced he'd experienced it (and was positive
his foot was on the brake), and an observer that said, "no, it was on
the gas...."

Feb. 27 (Bloomberg) -- Ford Motor Co., the world's second- largest
automaker, settled a sudden-acceleration lawsuit today brought by a
Cleveland minister who was left in a coma after his 1987 Crown Victoria
crashed into a neighbor's house.

Attorneys for Leon Manigault, 77, said a defect in his car's electronic
system caused it to speed up uncontrollably after he put it in gear. Ford
and Manigault's family reached a confidential settlement today just before
closing arguments were scheduled in the trial in state court in Cleveland.

Two things...

1) An out of court settlement in no way constitutes proof that
what was claimed actually happened.

2)  WRT spark plugs, you are actually claiming that if I install
Autolite, NGK, AC Delco or some brand other than Champion spark
plugs in a 1985 ChryCo vehicle with a turbo charger, start the
engine, disconnect the coolant sensor and check the ignition
timing with a stroboscopic timing light, I'll see different
timing setting between the different brands of spark plugs?

a.. Oct 4, 1996 :  Chrysler disclosed in a letter to the Office of Defects
Investigation that it knew of 98 incidents of unintended acceleration
between 1993 and 1996 involving Cherokees and another 241 involving Grand
Cherokees ref: See Section 9-Links & References CHRYSLER
a.. A group of independent engineering experts claims to have uncovered a
defect specific in the 1993-96 5.2 litre V8 Grand Cherokee. If cruise
control is left in the ON position a short to ground in the power control
module connector can cause the vehicle's engine to race. The short is said
to be caused by water, moisture etc. getting into the connector and causing
corrosion.  ref: See Section 9-Links & References CHRYSLER : Strategic

I AM SAYING. and not sure of all the plugs that were affected but i dont see
many of these vehicles in the shop. But a/c delco and Bosch plugs  and some
others would cause the timing to flucuate severly at idle, CUST COMPLAINT
idles very rough, Naturally if you disconnect the coolant sensor it goes
into limp ,  fan turns on and the timing is back to base timing and you
would get a steady reading.  Idle on those vehicles were controlled by
timing, Stern is wrong.. Cuda, the next time you work on one. See it for
your self. You may have already had them in the shop, put a timing lite on
it and watch the mark, with thecoolant sensor connected, then install
champion plugs and put the lite on it and see how stable the mark is, And
then notice how smooth the idle is

Okay, now where is the connection between the Jeeps, Fords,
Buicks and radar guns aimed under the hood cited in your link and
the 2002 Chrysler Sebring?
All you've managed to do Glen is point out that there have been
failures associated with -some- cruise control systems, that does
not mean that all cruise controls or even this cruise control
will behave or -did- behave the same.

Ever do a WOT test on an engine with it in gear with an engine
analyzer connected?
Ever check the stall speed of a torque convertor?

I have, hundreds of times, and not once were the vehicles brakes
incapable of holding the car back.

Whoa, stop right there.
Then the spark plugs per-se are not causing the timing change.
If the plugs don't change the base timing (which you seem to
agree to) then the only thing that can be changing the timing is
a signal sent to the logic module (since disconnecting the
coolant sensor takes the logic module out of the picture), that
signal most likely being from the knock sensor, due to the wrong
heat range spark plug being used, IOWs, the same result would
happen if the wrong heat range Champion spark plug were to be
used, so it is NOT the brand of spark plug that is causing the
problem, it is the implementation of heat ranges, the practice of
part number overlap that is the actual cause.
Specifically; the vehicles in question had the capability to
retard timing for individual cylinders.
Specifically: you claimed that the power module "sees" something
from the plugs in question, yet the power module (for the sake of
this discussion) only switches the coil primary, and whether or
not the coolant sensor connector is connected or not, the power
modules function in this regard does not change.

I can tell you specifically which AC Delco and which Bosch spark
plugs caused the problems that you observed;
Delco: it was the Rapid Fires
Bosch: it was any of their gimmicky crappy platinum plugs.
Why?  because those two are the biggest offenders in the "one
part number fits 5 heat ranges, the customer will never know and
we couldn't give a damn--it's all about the bucks" game.

You buffoon, the power module was called the power module, the
logic module (the computer processor) was called the logic module.
Quite strange that a dealership mechanic would get them confused
or forget that there were in fact two individual components.

Nope.  Last job I was fired from was, never.

I don't think he proved that there have been failures.  It isn't clear
if Chrysler agrees that these were unintended acceleration incidents or
has just received reports of them.  I'd be very surprised if Chrysler
has proof of this.  And the independent engineering report claims to
have found a defect that MAY be caused by water, etc.  It doesn't sound
like proof yet to me.

I'd like to know who the "independent" engineering experts are and who
they work for.  I bet there is a pretty good chance that they work for
the lawyers of people who claim there vehicle magically accelerated...

In 1995 when we went to the MoPar Nationals in Indianapolis, my
then next door neighbor Pete Dorn decided to enter his 1969 GTX
in the burn out contest.  440 4bbl automatic, drum brakes in the
rear, don't remember what the fronts were, might have been drums
also since the car was a cloned from a 318 Satellite, beautiful
car non the less.

We did some trials in the pits before the contest started and
determined that the brakes were just too powerful to effect a
show stopping first place finish.  So I clamped off his rear
brake line with a needle nose vice grips.  The rules said no line
locks, but said nothing about using hand tools.
Ol' Pete won the burn out contest and got himself a free set of
tires from Tire America which he mounted on some cop car wheels
(looked really good).
I just find it hard to believe that if a set of vintage 1969
brakes can hold back a strong running 440 4 bbl, that the brakes
cited in all these supposed 'events' of unintended acceleration
318 powered Jeeps can't hold back a late model smogger SUV much
less a wheezing 3.0 in a Sebring.

IIRC, the term Patrick Bedard used back when all those Audi's
were getting dunked in swimming pools all over suburbia USA was
"cognitive dissonance."

DO NOT USE PLATINUM PLUGS OR BOSH PLUGS< USE ONLY CHAMPION< i belive they
were rn12yc, some plugs will mess with the timing of the power module and
cause all kinds of idle problems. Almost like it is searching because the
timing is flucuating so bad

Idle was controlled by the timing back then, With autolite/bosh and some
other plugs.I say use Champion because I no that was the only one that I
know didnt create a problem.  The Power Module saw the resistors in them
and caused the timing to jump all over, causing extreme idle problems
hesitation problems and more I would bet you are one of those guys that
put everypart on the car untill given up and told your cust to take it to
the dealer... Is that so? The next time you get one of these vehicles, put
a timing lite on it and see for youself, but then again I bet you dont
know how to use one and here once again, you have no clue what you are
talking about

So, to answer your question: Yes. In what passes for the brain between
maxpower's ears, the 1985 Chrysler 2-module engine management system was
so advanced that it actually knew the difference between Champion's 10kohm
spark plug resistors and Autolite's 10kohm spark plug resistors and
Bosch's 10kohm spark plug resistors, and if it saw anything other than
Champion spark plugs, it went wild 'n' crazy and threw a timing disco
party. Amazing feats o' magic, eh?

YOU GOT IT!!!!
NOW FOR YOUR NEXT ISSURE MR STERN< DO YOU WANT TO TALK ABOUT THAT?

Nope, it didn't happen that way. Your wife hit the gas without knowing it,
period. I know it's less embarrassing and less expensive for her to blame
it on the car, but cars do not behave so much as they are behaved upon.

YOUR GOING TO TELL THIS OP THAT HIS WIFE IS CRAZY CAUSE THE CRUSIE SERVOR
COUDLNT DO THIS??

Have you ever heard of Occam's Razor? It's a scientific principle that
says the simplest explanation is usually the correct one. Now, which is
simpler? A  or  B?

A: Your wife stepped on the wrong pedal.

B: The cruise control on/off switch, the cruise control "set" switch, the
brake light and cruise-kill switch, and the SBEC "no cruise control under
30MPH, and only in the Forward direction" programming all failed at the
same time, the cruise control engaged and pulled the throttle wide open.

Not below 30 mph with your foot on the brake and the trans in "Reverse",

By the brand of spark plug. Weren't you listening? ;-)

HEY GEAR HEAD what does this have to do with what kind of car it is, are you
really that stupid or do you just pretend to be?
Lets talk gearhead.. give me a phone number or your yahoo id so i can im
you. since obiviously you wish to speak more and more and become close
friends. I was explaining this is possible that the accident could be
related to the cruise control servo. Sorry if i left out the finer anal
details. But that is why you are here to pick them up correct .

Stupid would be you. What else would explain your lack of ability
to operate a newsreader, YOUR newsreader.
You have posts from multiple authors attributed to me, that makes
you a king sized bozo and a person not to be taken seriously.

Now, why do you suppose the problem with Jeep cruise controls
stops at MY 1996?
What makes you think that just because there was a problem with
Jeep cruise controls in MY 1993, 94, 95 and 96, there is a
problem with 2002 Chrysler Sebring cruise controls?

> Lets talk gearhead.. give me a phone number or your yahoo id so i can im

I have plenty of friends, even the more stupid ones are much
smarter than you.

And it is possible that it isn't related to the cruise control,
but citing incidences of ten year old Jeeps and 18 year old Fords
as any way related is just plain ignorant.
Camshaft failures were real common on 70s era Chevrolets and
Oldsmobiles, maybe you should warn the OP about -that- also.
Something like;
ATTENTION jonz6@aol.com
Certain Chevrolet and Oldsmobile engines produced in the 1970s
suffered from premature camshaft wear, since you own a 2002
Chrysler Sebring, you should be aware that there is a possibility
of premature camshaft wear based upon evidence obtained when
reviewing failure records of the previously mentioned General
Motors divisions.

It's got nothing to do with the "details" it has a lot to do with
what should be obvious, like the make and model year.

Your posts look like sh.t, if I reply, my newsreaders spell
checker lights up like Las Vegas during a light bulb convention,
your replies run into the text of the person that you're replying
to, you fail at skills that are normally achieved by the age of
ten, and your logic and reasoning skills mimic those of a
Yorkshire Terrier, your stories change which makes them less than
believable, you insist on things that you obviously don't even
have a basic understanding of, hipcrime spam attacks are easier
to read than one of your posts, one can only imagine how many
hours per week your service manager has to waste trying to
decipher what you've documented on your repair orders, you've
shown evidence that you don't understand the basics of how an
internal combustion engine operates, you're a parts changer, you
embody every complaint ever lodged against Jiffy Lube, you
mis-attribute posts, 78.6% of what you post makes no sense at all.

All well and good but it doesn't address the problem that
someone might actually follow something that you've posted, you
know like change the cam and crank sensors when their timing belt
has jumped.

Yes, I'd definitely think that an attorney would be an authority on
electronic systems.  Major corporations settle law suits all of the time
whether they feel they are at fault or not.  The decision is based on
economics, not technical reality.  The Crown Vic may well have a defect,
but this hardly establishes that.

Oct 4, 1996 :  Chrysler disclosed in a letter to the Office of Defects
Investigation that it knew of 98 incidents of unintended acceleration
between 1993 and 1996 involving Cherokees and another 241 involving Grand
Cherokees ref: See Section 9-Links & References CHRYSLER
a.. A group of independent engineering experts claims to have uncovered a
defect specific in the 1993-96 5.2 litre V8 Grand Cherokee. If cruise
control is left in the ON position a short to ground in the power control
module connector can cause the vehicle's engine to race. The short is said
to be caused by water, moisture etc. getting into the connector and causing
corrosion.  ref: See Section 9-Links & References CHRYSLER : Strategic
Safety. Special investigation Chrysler Cherokee 1998

That was 1996, But it is possible that it can happen, as it is possible that
