This might be difficult to explain in writing. My 2023 RDX Technology has a slight bounce and swaying when driving down the road. My 2009 Accord and wife's 2022 Toyota Highlander ride down the street mostly level with the road. But in the RDX it feels like the car finds some imperfections in the road that make it rock or sway a little bit, almost like the suspension is too soft. It is not a lot of rocking or swaying, but it's noticeable. And it's not worn shocks because the car only has 18,000 miles and it doesn't oscillate much.
I think it's maybe related to it being an SUV with high center of gravity, large wheel travel, and slightly soft springs - I think. Is there anything that can be done to reduce the swaying and rocking? Would stiffer struts or shocks help? It would probably be expensive to replace.

Thanks.

 

Have you checked the tires pressures? Also what driving mode are you using? Sport, Normal, Comfort or Snow.

 

Tire pressures ranged from 30 to 34 PSI, depending on the weather. On the Tech trim, the mode didn't affect the suspension, only the shifting. Those are things I tried and didn't help.

 

Those are low tire pressures to me. I run 39 PSI year round (believe the door tire card recommended is 34-35 PSI), better mpg, handing, roll resistance and a slightly firmer ride (which I prefer).

To the OP - the RDX does sway a bit side to side when driving - it's just the way it's designed (higher center of gravity and suspension).
