Our 2005 Mustang GT Premium came with the Shaker 1000 factory upgrade.
We've had two problems with the car that are forcing us to use the
Ford arbitration / Nebraska Lemon Law process.  If anyone else has seen
these issues on the 05 Mustang, please post a reply.

1.  The stereo will not stay at a constant volume when the "shaker"
is turned on.  When the Shaker is turned off, the volume works
properly.  CD's, MP3's, or AM/FM - it doesn't matter what your
listening to, the volume drops about 10 volume clicks as soon as the
"shaker" is turned on.  However, at the beginning and end of each
song, the volume goes back to normal for about 2 seconds.

Personal note:  it seems to me that the Shaker System has a faulty
wiring/circuit issue.

2.  Something is draining the battery.  If the car sits two days, the
battery is pretty much dead.  It doesn't matter if the stereo is turned
off or not.  The battery will be dead if unused for 2 days.  The
battery has been replaced.

Personal thought:  Wouldn't a faulty stereo system/wiring harness drain
the battery if it were not turning itself off when the car was shut
down?

The Shaker 1000 upgrade is a $1,200 factory upgrade, and when it does
work properly, it's awesome!

Here's some history (I'm venting now) on this car and some of the
"processes/procedures" that we've encountered over the past 7
months dealing with Ford and the dealer (Atchley Ford in Omaha).

We've had the service tech's at Atchley Ford tell us that it takes
45 minutes to diagnose each amp in this vehicle (there are six amps
total in this vehicle) and the diagnostic tests must run consecutively,
in a specific pattern.  Each issue with this stereo requires the
mechanic to re-start the diagnostic test, which means about 6 hours in
the shop for the car owner.  Normally the diagnostic tests don't
finish, which requires the technician to restart the entire process.

Ford has required our Ford dealership (Atchley Ford in Omaha) to send
in the defective part(s) because their process is to fix and return
defective parts.  It took three weeks to get the first two amps
repaired (actually Ford said they would repair them, but ended up just
sending back new amps).

There were 3 other Mustangs with the Shaker System on the dealers'
lot.  Ford would not allow Atchley Force Service Department to swap out
the stereo system with another car to help trouble-shoot the problem.
Guys and gals, It's a plastic box in the trunk with maybe three bolts
and only two power connectors keeping this thing in the trunk.

So far to date, we've had the stereo system replaced, the amps in
each door replaced, portions of the Shaker 1000 system in the trunk
replaced, the battery replaced, and a relay/time-out switch replaced.

Ford brought in an engineer several months ago to help diagnose the
problem.  He ended up replacing one of the amps in the trunk and the
problem was resolved for about 30 days.

Here's another interesting tidbit of information:  Ford will not
allow us to take this vehicle to another dealer for trouble-shooting.
We are required to drive over 40 miles each way and utilize Atchley
Ford of Omaha when there's a Ford Dealership only 10 miles away from
our house.  (Yes we tried the dealer-swap prior to purchasing, but
Atchley wouldn't let the car go since it was a dealership in the
local area).

I spoke with Chris Rodgers, the Sales General Manager at Atchley Ford
yesterday about swapping out this car and he seemed eager to help make
this right.

I've never gone down the road of arbitration /lemon law, advice would
be appreciated.
