AHC Issue

There 54,000 miles on my LX.

Ok. As some of you have seen, I bought a new to me 2014 LX 570. I has a CarMax 90 day warranty. I am finding it has a very rough riding front right wheel.

I suspect the damping force actuator accumulator is flat or close to it. CarMax is starting to indicate they don’t think there is a problem. If I hit a pothole on the highway with the left front wheel, no problem. If I do so with the right front, vehicle bucks and wheel jumps back and forth in my hand violently. I could argue truthfully it is not safe to drive.

Any thoughts on what problem might be and on how to approach this with CarMax?

Suspension manual attached for you which might help. There are a lot of threads on here about AHC including fluid changes and testing globes. The front two wheels are linked via the Height control value (see CH-155). Check the ECU faults as a first step via OB2 tool or get someone to do it for you. I'd strongly suggest getting some professional input to read the pressures in the system and check the bushes and globes.
