Default 3rd Gen Lexus RX350 hard suspension

I was wondering if anyone can chime in on the "problem" I'm experiencing,
I own a '11 Lexus RX350 and I noticed the suspension is REALLY hard. When I go over bumps, potholes etc the car doesn't smooth it out at all. I was wanting to know if it's an issue with the suspension or is this just how it is?

Any help would be appreciated.

Do you have the 18" or 19" wheel package? Which brand tires?

I have Latitudes paired with 19'' rims.

Check the psi and to be 100% sure, have a technician drive with you next time you (or your dad) bring it in for servicing.

I have the same wheels and tires. I also have the f sport which has a firmer suspension. But I have noticed over the past year the tires have worn out very fast and the ride has gotten worse because of it. When the tires were new the suspension provided a firm yet compliant ride and the tires seemed to soak up most of the road imperfections. Now I am experiencing what the tirerack reviewers noted- that the michelins ride hard, and road imperfections are felt with a significant thump in the cabin, compared to other tires they tested. I'll never buy michelins again. Bridgestone and continental seem to make much better tires.

Yup I remember, I followed your advice and adjusted the PSI and still no difference. I've arranged with my dealership to drive another RX they have in stock to see if I experience the same drive. But I do remember seeing the '11's have issues with their suspension so I'm wondering if that has anything to do with it.

You are right Michellin's are total garbage. I switched to Yokohama Advids on my Corolla and they are much better. I might try them on my RX when the time comes.

Which Michelin Latitudes are you talking about? The Tour or Sport?
The Sports have a terrible tread life rating.

If you put Michelin MXM4 Pilots on you will change your tune. Best riding tire I've seen.

I have noticed a hard ride on my 2010 RX 350 (FWD)
It has the Yokohama tires: 235/55 R19
They are set to 32 psi.
I think this is a lower profile tire

I run Sumitomo's (235/65 R16) Touring on my other SUV and even at 36 psi, they ride better and quieter.
It is a smaller wheel and taller tire profile.

My favorites were Pirelli Stingers (scorpion logo), but they were so soft they wore badly and too fast.

I have the tour version. I hate them. I have heard good things about the mxm4s but the problem is they are $280 per tire! Some others have been rated much better and cost more than $100 less, like the Bridgestone ecopias and a continental set that was rated number 1 on tirerack.

Update*** I took my Lexus in and they noticed something was wrong with the suspension. They didn't tell me which part it was but they will be replacing it under warranty Tuesday.

We bought an '11 RX350 CPO last November. The ride seemed rough then. Yesterday, on typical highway road conditions, it rode like a truck. Felt every bump and road irregularities. Seems to be getting worse. 18" Bridgestone Dueller M+S. Probably factory tires. Took it in two weeks after purchase with the rough ride concern. Dealer said ride is normal. Roads around the dealership are smooth. No way to adjust shocks per dealer.
I'm very interested in what Dat Dude discovers. We're under warranty.

Raylor I'll definitely let you know what happens. Based on how you described the ride I feel we both have the same issue.

I also experience very harsh ride over small potholes and expansion joints. Like a freaking truck with solid axles. So I am also very interested in the results here. Thanks.

The rest of the ride is just fine, but this really makes no sense. Your average Ford (nothing wrong with Ford ) has much better handling of these bumps. I may be driving an Edge soon enough.

For sure Dave I'll post what they say hopefully by the end of the week!
