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)
2022 Mercedes-Benz EQS 450 driver assistance complaints
Page 2 of 2: complaints 11 to 23 of 23, newest first, as owners wrote them.
I was driving my EQS on Thursday May 25th, 2023, at about 1:30 PM heading eastbound on the southern portion of the 202 Loop in Maricopa County AZ at a rate of about 75 MPH on a clear day with minimal traffic when without warning my vehicle locked up the brakes in an emergency stop. The tires left skid marks, seat belts tightened, and the screen in form to me flashed red warning signs. It happened so fast and without warning that when I realized we had come to a stop I look in the rear-view mirror and saw a truck headed towards my car, so I accelerated, and the car moved forward. Once off the freeway I drove the remaining 2 miles home along city streets at a low rate of speed and contacted Mercedes and Mercedes Benz of Gilbert. I was told that there was a defect int eh software pertaining to the EBS and that a software update would resolve it. I have the car back now but do not feel safe in it.
Driving about 40 MPH on a slight curve, with no imminent danger ahead, the car automatically applied the brakes full force. If there had been a vehicle behind me there probably would have been a collision.
The 2022 Mercedes EQS 450 has been an ongoing dangerous driving experience for me. I have been jolted and frightened over and over as the car's autonomous emergency system fully engages when driving as well as when it does not engage when I’m stopped at a light. I have expressed my safety concerns on numerous occasions to the management at the dealership. As I am writing this I see on your website, there is an unrepaired recall on this car with a remedy not yet available. In April, 2023, the car stalled and the messages below appeared on the dashboard: Attention Assist System Suspended Malfunction. Drive at max. 50 mph Stop Vehicle Level Too Low When the car was at the dealership, I was told, while it is a new model, they are trying to figure out the problem. I no longer want to be a guinea pig and endanger my life driving this car. In October, I backed into a low brick wall when the sensors did not alert me. At that time, I told the service department about the sudden braking and stalling. I had the damage repaired, costing $7000 and was told all was fine with the electrical panel. The dealership is now telling me after the car was there for 2 weeks, the car is fine. After being told this in October and with ongoing issues, I have no reason to expect it to be any different this time? I feel unsafe driving this car and do not want to jeopardize my life. Originally I was told Mercedes is aware of these issues and they would offer me a buy back and walk away. Now they are saying the car is fixed but Mercedes will offer me $5000 towards a trade-in and $70,000 for my car with less than 3000 miles. Offering me a substantially less amount of money than I paid for the car with on going safety issues is not acceptable.
The contact owns a 2022 Mercedes-Benz EQS450. The contact stated while reversing out of the driveway, the vehicle experienced phantom braking. The contact stated that while driving 30 MPH, the failure recurred while there was no vehicle or objects nearby the vehicle. The contact stated that while driving 40 MPH, the failure recurred, and the contact was propelled towards the steering wheel. An unknown warning light was illuminated. The vehicle was taken to the dealer, where an unknown software update was completed; however, the contact requested about a buy back because he was concerned for his safety. The contact was unsure whether the vehicle was repaired. The manufacturer was notified of the failure, and a case was filed. The dealer later informed the contact that the manufacturer had denied the buyback request. The failure mileage was approximately 7,000.
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.
While driving at approximately 45 miles an hour with nothing in front of me and no objects in the road, the vehicle activates the emergency braking system and attempts to stop in the middle of the road. It activates the seatbelt retentioners, as well as all of the safety warnings at the time. It does this with no apparent warnings or trouble lights on the dash. This puts me at risk to injury to my body being thrown around, neck and head threw forward. It also stops in the middle of the road potentially causing me to be rear ended. This happened at 500 miles on the odometer and at 1041 miles. I only took delivery in December. It has happened twice.
On several occasions driving at 50+ mile per hour maintaining a safe distance and with no hazards around, the vehicle abruptly stops and the last time it skid damaging my rim. 1) It appears that the electronic braking system (EBS) is defective. 2) My safety as well as vehicles behind me are at risk of collision due to this problem. 3) I brought this vehicle to the dealership and they claimed that they worked on it and asked to come back if this issue happens again. 4) This vehicle has been taken to the dealership but I'm not sure if it was inspected by the manufacturer. 5) There were no warning lights, no messages or any symptoms which makes this nerve wrecking since it can happen at any moment. The first time this occured was in April 2022, then in July 2022, September 2022, and finally December 2022 at which point I brought the car to the dealership since I feel that I'm in danger as well as other motorists/pedestrians while this car is on the road.
I was driving at around 45 MPH, without any cars around me, and suddenly the car abruptly stopped. There were no obstacles or any reason for the automatic emergency brakes to engage, and thankfully there were no other cars around, or else there would have been a collision. This was a very frightening experience, and I am thankful this didn't happen on the highway or at a higher speed, as that would have resulted in a significant accident. I have only had this car 3 weeks!!
Driving on I-75 south of Ocala as I drive by the State Weigh Stations the EQS sees a 45 MPH speed limit sign off to the right so the Adaptive Cruise Control starts drastically reducing my 75 MPH to 45 MPH in the passing lane. I have to floor it to maintain speed. This has also happened as I drive by a left entry ramp with a reduced speed limit
On four instances my car thinks that there is an object in front of it and automatically initiates emergency breaking. It happened today TWICE at 67mph on a highway and I almost got smashed by semi behind me!!!
On two instances the car thinks that there is an object in front of it and automatically initiates breaking. Today it did that and a driver almost collided into me.
I was traveling at 75 mph along the freeway on a clear day around 2pm when all of a sudden the car's autonomous emergency braking system fully engaged and brought the car to a dead stop. there were no obstacles or impediments in front of the car or near the car at the time. It was terrifying and could have resulted in me seriously injured or killed if there had been any vehicles traveling behind me. This had happened twice previously with the car but in less dangerous conditions and at lower speeds, but this time it was much worse. It has caused me a lot of ongoing anxiety and mental anguish and I feel very emotionally distraught by the incident. This is a brand new Mercedes EQS vehicle that I have only had a few weeks.
