2024 MERCEDES-BENZ Glc 300

Attention Assist System Suspended notification comes on randomly on vehicle while driving, rendering driver defenseless with regard to safety warnings that would otherwise be in effect, such as blind spot assist, attention assist, which are vital components for safe driving. This has happened on numerous occasions, most recently on 12/06/2024 while driving under destination route guidance. It has also happened when car was stopped to retrieve mail at residence mail box and, at other times for no apparent reason, while driving. Each time when engine was restarted the dashboard read 'System suspended' and continued to do so until car was returned to dealer. This vehicle was purchased on 12/21/2023 and with less than 350 miles began repeated problems with warnings, the first of which was "Check engine"on 02/02/2024, as car was running rough. Car was repaired(dealer determined cause was electrical/software error, fault code) yet before driving out of the dealership the same 'check engine' warning reappeared and vehicle had to be returned to service that same day for the same problem. Since that date in 2023, this vehicle has had numerous seemingly computer related issues that render it unreliable as to the safety devices this vehicle features that should always be maintained. On 03/21/2024 with less than 950 miles the fans remained running after shutting vehicle off and a message appeared stating" cooling system malfunction/reduced drive performance" with a red triangle on dashboard. Dealer determined the cause was 'SOFTWARE" At this point I am concerned that this vehicle is over engineered with computerized options that randomly fail. On another occasion the lights on one side may have been on overnight. The lights (courtesy lights) were on on the right side overnight in garage. My safety is continuously at risk whenever a warning appears.I replaced my GLK specifically to have Blind Spot Assist, PRE-safe, Attention Assist, Active distance assist and other features.

OUR SUV IS 6 WEEKS NEW AND WAS PURCHASED NEW AT THE MERCEDES DEALERSHIP. REAR HATCH: WHEN STANDING BEHIND VEHICLE REAR DOOR HATCH CLOSES RANDOMLY WITH NO WARNING OR BEEP. CLOSES VERY QUICKLY AND HITS HEAD VERY HARD. FEET ARE NOT NEAR THE BUMBER WHICH ELIMINATES THE REAR FOOT ACTION THAT CLOSES THE HATCH. WHEN THE HATCH HITS YOUR HEAD IT COULD KNOCK YOU OUT ESPECIALLY IF YOUR EDERLY OR A CHILD. ALSO IF YOU TRY AND STOP THE HATCH COSING ITS VERY STRONG AND TAKES A LOT OF STRENGTH. WHEN YOU USE THE REMOTE OR BUTTON IN CAR TO OPEN HATCH IT OPENS SO FAST AND BEEPS TO LATE TO ALERT DOOR IS OPENING. VERY DANGEROUS. THIS PROBLEM HAPPEN SEVERAL TIMES AND IS RANDOM. THE LAST TIME IT HAPPEN WAS SUNDAY 9-1-24 WHILE LOADING GROCERIES AT COSTCO

Brand new '24 GLC300 4MATIC. Engine light came on with no error message. Brought it in for service. Miscellaneous engine repair states: "Found current code POA7F00 in drivetrain control unit. Followed LI54.10-P-077250. Cleared codes. Drained 48V battery to below 25% SOC. Charged vehicle to 70% SOC. Job complete." Service foreman mentioned that the service performed may not resolve issue. He contacted Mercedes-Benz Engineering and said no fix at this time and no ETA. Left service with no more engine light on. However, it didn't take long, and the engine light came on again. I called service again, and I was asked to take the car back in to be sure it is not anything else. Took my vehicle back, and service foreman diagnosed the issue. Code is the same as before with issues on the 48V battery. Service foreman is unsure of the exact issue. Mercedes-Benz Engineering did not provide details of the problem. I believe this issue poses a safety risk without knowing for sure what is the real cause and what might be the effects on the vehicle. This GLC is my family daily use, and it has become a big safety concern on the road. Service was very helpful and accommodating with my vehicle's issues. Unfortunately, fix is unknown from Mercedes-Benz to be able to resolve. I have also called the Mercedes-Benz Customer Care, 800-367-6372. Unfortunately, there is nothing they can do. I've asked to open a case. Case # [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
