F.T. Frick

I don't know how many people are still trying to find out what causes a squeak in a 2015 and other year models of Lexus RX350. There are no recent posts. I read that a lot of people took their car in to the dealer to have their suspension worked on and the various repairs did not eliminate the squeak. I finally found out what was causing mine. It sounded like a chirp coming from the right rear when I went over certain types of bumps. I found that the noise was coming from the spare tire cover. There is a metal strip on the right side of the cover with a tongue on the end. The tongue slips into a holder. I made sure the cover was well seated and that the tongue was also well placed in the holder. I was prepared to use padding on the tongue if necessary. I didn't have to. It's been at least 6 months and I haven't heard the chirp again.
