Garage flooded. Is my car OK?

Due to incredible rain in the NYC area, my garage was flooded. I was out of
town when the flooding happened and the water level in the garage was about
12-15 inch high according to the stains on the garage walls.

My '06 Lexus ES330 was in the garage and I see NO evidence of water coming
into the interior. The interior was dry when I opened the doors. I just
brought the car back from a friend's and during the short ride, I didn't
hear or feel anything strange (I thought I heard sound of liquid moving
somewhere in the car, but I'm not sure if it was real or my imagination).

What are the symptoms of water damage to a car? Should I bring the car to a
dealership?

Pretty much everything outside of the interior that low is going to be
meant to get wet. Somethings might not like being submerged though. The
things to check would be for water getting into lubricated items that
were not meant to be submersed. Be that water geting in through a vent or
a past a seal. It wouldn't hurt to give it a good inspection before
driving it much. At worst you might be looking at repacking bearings or
changing out the fluid in the diff (if RWD and having a vent that allowed
water in).

Electrical connections should probably be checked as well if they aren't
of the sealed type.

Anything exposed that low is going to be sealed from the weather. Take it
for a long drive to get everything warmed up good should clear out any
moisture. I assume you did look at the oil dipstick and transmission. Any
water would have raised the levels.

Here's an update:

When I abruptly stop the car, I hear a sound of moving liquid from the rear.
So, I guess water is trapped inside the muffler:-(

Possible, but less likely than water in the trunk, quarterpanels, or
the rockers.

If there is water in the muffler, drive it and it'll blow out and/or
evaporate.

I think having an 1/8" hole in the end of the muffler to let out water
is a good idea.  Some come with them.  This also lets out the
condensation that rots out mufflers from the inside out.  (ever notice
that?)

it is a very good idea, but the OP should be warned that it can change the
sound of the exhaust at idle. (yes, even a 1/8" hole)

Perhaps some liquid in your gas tank?

I agree.
To verify, remove the tank and go for a long drive to see if the sound stops.

Take a two-hour drive on the highway and you'll boil it all right out.

You should have it checked out by a good mechanic at a minimum.  12-15
inches is high enough that you probably ought to have all the fluids
changed and the wheel bearings and CV joints repacked "just in case."
Hopefully it didn't reach the level of any crucial electrical
components.  If your carpets remained dry that is a good sign.

good luck,

You're talking out your a.s.  The wheel bearings and CV joints are sealed.
Have you never heard of driving a car in a heavy rain storm?  Hitting
deep puddles and splashing everything with water is going to get everything
just as wet.

If water got into the exhaust, it'll get blown out and evaporate.  Don't
go drilling any holes.

Bring it into the dealer for a quick checkup and quit obsessing over it.

CV joints, fairly well sealed.
Wheel bearings, often less so.

But yes, getting bearings and such regreased is a bit overkill.

Probably the first problem will be the E-brake sticking, if it has
drums.

If wheel bearings are so well sealed, why do they sell special dust
caps for boat trailer wheel bearings with grease fittings in them?

Personally if it were my car i'd check everything just to be on the
safe side.

 I thought the OP was talking about a car, not a boat trailer ; )  Most
automotive wheel bearings are a non serviceable sealed bearing assembly,
there is no way to check it or grease it.

  Boat trailers use removable, servicable wheel bearings that aren't sealed
as well. The problem you have is that when you back a hot wheel bearing hub
into cold water it sucks the water into the hub and eventually causes the
bearing to fail. If you can fill the hub with grease you don't have that
problem. That's why you have the bearing cap with grease fitting.

Judging from my cars, the bearings are sealed well enough for rain
and spatters from water on the road, but holding them underwater
for hours to days might be asking a lot.

He'll know soon enough, I guess.

I will just say this.  When I do a grease job on my Jeeps after every
off road camping trip that had water crossings, I get water out of
'every' fitting I can possibly grease, especially the u-joints.  Things
like the tie rod ends and ball joints are really open to water, then the
grease and the dust seal can hold it in and rot things fast.

Things like CV joints and wheel bearing 'do' get contaminated with water
and mud and need to be opened up once a year on our Jeep to be repacked
because of it or they 'will' fail.

I had to stop using those Heavy Duty 'lifetime' warranty 'no grease'
u-joints because they lasted only about a year due to water
contamination.  I mistakenly thought they were better so put them every
freaking place when I rebuilt my CJ7 and used them on my Cherokee.  What
a pain.

I also have a really high instance of brake lining failure due to water
contamination.  I have only once in over 10 years been able to wear a
set of brake shoes out, normally there is 40-60% left on them when they
break apart into pieces or delaminate from the backing plate.  Cheap
ones, expensive ones, no matter, none of them like to be submerged in water.

If the OP can possibly get a grease job done, it is recommended.  'If'
his wheel bearings are repackable, that too.
