Hello All, yesterday I was driving my car after few days in the drive way. As I was driving the error code " chassis stabilization,drive moderately" popped up. I was not able to switch drive mode. I then parked the car, turned off the engine and start it back up. The car back to normal again. I took it to the dealership, they tell me it could be triggered by the pothole or bump. The car drives perfect. Just wondering if anyone has experience this ? Is this something I should be worry? The service advisor tell me if it come up again I can bring it in. But for now, it doesn't seem has any issue! Thanks in advance!
