Shortly after I took delivery of my IS350, its rear suspension began making an odd sound over road imperfections (bumps, potholes, expansion joints, manhole covers, etc.). The sound is most pronounced on the rear driver's side wheel, and it's becoming more noticeable and common with time. The best I can describe it is as a high-pitched, metal-against-metal, clunk/squeak. My car currently has 2,700 miles on it. I've never heard any CL members mention a similar issue, so I'm assuming this isn't a common 2IS problem.

Does anyone have any idea what the problem could be? And if so, should I wait until my 5k service to address this issue?

Thanks in advance.

 

yes i have that as well. even with my Teins on

 

Check the shocks.....I saw another member on this board had that problem. The shock was leaking.

 

Don't wait, take it back before it leads to something else

 

Thanks for the advice.

It's become so common that I'd be able to replicate it on the first manhole cover I come across with a service technician riding with me. Even slight ripples in pavement cause it.

 

I have that too... But it doesn't happen all the time... Thank god for the warranty... When I have time I'll take it in.

 

5 year bump!


I have the same squeak on the driver side rear suspension. I had blown the rear shock and thought that was the problem. Had brand new Megan coils put on and the same squeak is there. Any ideas? With my shop under there to install the coils I imagine they would have seen something if it was noticeable...
