NHTSA Complaint #11581069 — 2021 TOYOTA CAMRY

For three consecutive days, while driving on the highway (speed between 50-60 miles per hour, with a speed limit of 60 miles per hour), the car experienced unstable posture, skidding, and sudden severe shaking, as if it were traveling on water, especially frequent on bends! When driving at a lower speed (between 45-60 miles per hour, with a highway speed limit of 65 miles per hour), it feels like driving on a slippery road. The first time this happened, the road surface was normal and not slippery; the second day, the first occurrence was during rain, and I thought it was due to wet road conditions, but the second and especially the third time, the road surface was dry, and there were no wet or slippery road conditions. Today is the third day and the same issue occurred again. Personally, I suspect it may be the result of improper intervention by lane assist functions.This is the first time I've encountered this situation in all my years of driving."
