My 2010 RX 350 only has 35K miles and I've been feeling that the smoothness in the ride has really deteriorated in the last several months. So much so, that even though I could have squeezed another 5K or so out of my tires, I bought a new set...OEM Michelin Latitude Tour HP. I can't say the ride has improved at all. Today, I brought it to the Lexus dealer for a brake inspection, because I was getting a slight vibration in the wheel when braking. Front brake job was needed. I was given a 2013 RX 350 as a loaner. The ride in that car is so much smoother. Should I be questioning the suspension or some other issue that would improve the ride?

What was your original set of OEM tires that you replaced? Michelin too?

desnard

Yes, OEM tires were same model of Michelin.

Check your rear shock absorbers, they may be worn. Common issue with the 2010 RX. Dealer should replace for free if they are leaking.

Also, have them check the steering column. This is a known problem with early 2010's. I had both my steering column and rear shocks done. It should be done under warranty. I believe there is a TSB on both items.

Thanks so much for the tips sacherel and bextreme1. I did have my shocks replaced about 10K miles ago. I was actually squeaking. I'll get them to re-check.

First check is tire pressure. Be sure the tires aren't overinflated...

That should have no impact on the ride...
