MERCEDES-MAYBACH Complaints

Driving on interstate 95 in South Carolina in the high speed lane Saturday December 2 2023 late morning. Adaptive cruise control, lane keep assist, self driving modes engaged. No traffic in front, large semi truck next to passenger side about equal to side mirror, I believe it was advancing. Car sounds collision warning beep and executes full emergency barking with seat belt tensioners emergency retraction. The system quickly releases the brakes which may have been the result of me pressing the gas pedal, I am not sure as this all happened in fractions of seconds. I disengaged all self driving and distronic systems including parking sensors and continued on the journey.

2nd issue with objects in tire and losing air. There are known issues with this new model and the combination of the 21"rim, new model series, and Pirelli tire.

I leased a 2023 Mercedes from Grapevine Mercedes. When I test drove the vehicle the car had a check engine light on. The sales man said he would get that fixed. The salesman had the service tech clear the code without addressing the issue. A week later the check engine light comes on. The dealership has advised me that the car has a software issue and its unsafe to drive. They must wait for technicians in Germany to fix the problem. It will take weeks. There is a chance the car will shut off while driving.

I have had two separate incidents where the automatic braking system engaged causing vehicle to come to a complete stop almost causing me to get rear ended by another vehicle. The first time there was no sign of a vehicle in the front of me. It happened at about 55 miles an hour on the expressway. I took the vehicle back to the dealer and they claim they haven't had any issues so they download some new software and said that should take care of the problem. The second time happened today. I was entering a roundabout at 15 miles an hour (there was a vehicle about 15 feet ahead of me) my vehicle suddenly stopped (vehicle behind me hit their brakes almost hitting me). I emailed the dealer a video clip of the incident but have had no response at this point. I have lost confidence in the safety of the vehicle at this point. I have a dash cam video I can send if needed.

THE CAR SUDDENLY STOPPED WHILE DRIVING ON THE ROAD AND THEN WOULD NOT ENGAGE GEAR. THE MONITOR DISPLAY SAID 'MALFUNCTION'. THE CAR HAD TO BE TOWED TO MB DEALERSHIP. THE CAR WAS LEASED ON 5/28/2017 AND HAD LESS THAN 150 MILES.
