Car is equipped with Distronic cruise and has maximum 4 car lengths stopping distance. It was set on 4 car length. While driving north on 55 fwy and exiting to 405 fwy in California. Exit (single lane) was dead stop due to traffic and while I was on cruising at 70 mph. Car would not stop and I had to take over to stop- hard braking just in time. The SUV behind me had to swear to emergency lane ( right side) to avoid a rear end collision. All my family (4) were screaming that it could’ve been a serious accident. This has happened more than once. Even on the surface road reaction to stop is late and jerky. My self and my wife hates it. 3 attempts at the dealership has not resolved it. [XXX] of Ontario Ca answer is, it up to the specs. My request for repurchase was rejected as it doesn’t fall into Lemon law. It is a major safety defect and can be dangerous to use of Distronic cruise. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
i am an owner of Mercedes 2022 EQS, living in Westchester, New York. There are a number of flaws in the auto drive software system that the company refuses to acknowledge. 1) the sensors on the passenger side of the car do not register a car immediately adjacent to you. Thus, while the auto steering feature still keeps the car within the lane, if the car to the right lane of my vehicle is adjacent to me, there is no way for the auto steering to compensate by moving toward the left of my lane to avoid physical contact with the other car if they are teetering left in their lane. This is particularly dangerous on highways when traffic is moving at breakneck speed and/or 18 wheelers occupy the middle lane. 2) the auto drive feature does not keep the car in the middle of the lane when the road veers either left or right. The auto steering allows the car to veer onto the lane lines before overcompensating and veering far to the other side. 3) if you are traveling on the highway in the far left lane, and the lane line is painted too close to either a barrier, or a curb, the sensors on the left side of the car do not register that the lane line remains intact and to follow that course. The auto drive shuts off completely and the speed drops immediately. 4) If you are traveling at 65 MPH on a highway, and drive past a exit speed sign of 20 MPH, the auto drive immediately reverts to 20 miles an hour without warning.
