#236 of 266 Thumping noise in rear.
Dec 09, 2009 (8:20 am)
Thanks for the information guys. My 09 CTS with 14,000 also makes the noise when going over a speed bump or other large bump. Coincidentally the car is at the local Caddy dealer now for that and some other issues such as brake squeal, leaking headlight washer nozzle, squeaks and creaks and a defective shifter switch. Will be interesting to see if dealer diagnoses the wheel bearing issue without me telling them of the "service bulletin". I love my CTS but seriously think mine is somewhat of a lemon. Either that or they dropped it off the truck when delivering it new

havent heard of the bushing issue...my 09 is quiet with 21K on it..however did have the brake squeal.....the only fix is to replace the brake pads....and add the new caliper pieces.....all in the TSB.....dont drive off the lot unless they replace the pads.....otherwise...it will come back in about 1000 miles.........

thumping in 200-9 cts is not a wheel bearing issue, ut is something to do with bushings for alignment of the rear end. it is in the service bulletin.

"noticing a noise coming from the rear which sounded like I had something loose in my trunk. I would hear this sound occasionally when I would go over a bump."
I am not discounting the service bulletin, BUT I had a similar noise. After a lot of investigation (by me), I discovered the battery cable was hitting its enclosure. A small piece of self stick foam insulation at the point of contact solved the problem.

Thanks again for the insight. The dealer claims that on my car it's not the bushings, but a different service bulletin regarding the rear quarter panel. They allegedly took care of the problem, yet the car still makes the noise. Anyone else ever heard of or had this issue, or leaking headlamp washer nozzles? I firmly believe the local dealer is incompetent, as they can't correct either problem, but the next closest dealer is over an hour away. BMW here I come.

Since they replaced the bushings, the difference is dramatic. No more noises, car feels better. Their diagnosis was correct.

Is anyone else having problems with leaking headlamp washer nozzles and defective gear shift assemblies?

#245 of 266 How about a sqeaky seat?
Jan 27, 2010 (10:42 pm)
I have 7,000 miles and I only weigh 165 lbs. However, the lower back of the drivers seat just began to sqeak if I move or put any pressure on it. I've never had anything like this in any car. Has anyone had this and what was the resolution. I will be taking it to my dealer next week.
