Does anyone have the issue of hearing squeaking noises form the back seat when going over large humps, dips, holes, etc?

 

I find that sometimes the sliding cover makes noises if it's not set properly, especially when it's cold out.

 

I have a 3RX, but I also find that the cargo cover will occasionally make noise especially when it's cold out.. But the noise is more of a rattle than a squeak if that makes sense..

I had one RX 350 the backseat behind the driver side that no matter what we did the squeaking wouldn’t stop. We took it to multiple Lexus dealerships and Boone could fix it! make this thing stop. Every time we went over a bump it squeaked it was very very annoying. I was so glad to get rid of the car. When I got my new Lexus and hit a bump it was strange to hear no squeaking. I wish I had some advice for you to get it to stop, but I don’t. Other than unloading the car it depends how much it really bothers you or you can always take the seat out. I don’t know if that is an option for you. It’s amazing how much a small thing like that can be really annoying.I have owned numerous RX 350s and only one of them has had that issue, and NEVER AGAIN! Good luck!!

 

There’s a TSB out for the rear trailing arm bushings - basically, replaced if they squeak when going over bumps.
