The seat belt latch in the second seating row, the outboard seatbelt latch plate retracted into the area between the c-pillar paneling and the rear side paneling. The rear occupant was not be able to fasten the seat belt latch. The latch plate retracted behind the panel and the seat belt for the affected rear seat was not be available for fastening. I was able to grab the latch plate with a pliers and bring it out from behind the panel but I am afraid this situation will occur again. I checked my VIN against you checker and it says NO RECALL is pending. I assume MB did not include this VIN in its report to you or falsely claimed the vehicle was repaired. reference # 2018030012, May 2018

WHILH E DRIVING WITH A PASSANGER IN THE FRONT SEAT, AND PROPERLY BUCKELED UP. THE PASSENGER SEAT BELT WILL RANDOMLY TIGHTEN UP AND THE SEAT BELT LIGHT WILL FLASH ON THE DASHBOARD AND THE SEAT BELT AUDIBLE BELL WILL SOUND, THIS WILL LAST FOR A FEW MINUTES AND THEN STOP FOR A FEW MINUTES THEN START AGAIN. I WENT TO THE DEALER AND GOT THE EARLIEST APPOINTMENT TO GET IT FIXED WHICH IS OVER 30 DAYS AWAY (7-26-22), I ASKED WAS IT STILL SAFE TO DRIVE THE SUV AND WAS TOLD TMHEY BELIVED IT WAS OK BECAUSE IT SOUNDED LIKE A SEATBELT LATCH ISSUE, I HAVE DISCIVERED THERE IS A RECALL FOR THIS PROBLEM BUT NOT MY MODEL YEAR

While driving vehicle, the seat belt pretensioner is activated and the seat belt light and alarm is activated. This cycle occurs throughout the drive, regardless of speed. Seems as though the seat belt latch does not sense that the seat belt is activated. This is very distracting to the driver. We reported the issue to the dealership, but have not heard anything since the report. This problem occurs on and off, randomly. May occur for a week straight, then stop for a day or two, then start again.

TL* THE CONTACT OWNS A 2017 MERCEDES BENZ GLC300. THE CONTACT STATED THAT WHILE HIS WIFE WAS DRIVING APPROXIMATELY 40 MPH, THE VEHICLE CRASHED INTO A 2ND VEHICLE. DURING THE CRASH THE FRONT END WAS SEVERELY DAMAGED BUT THE AIR BAGS DID NOT DEPLOY. ALSO, THE COLLISION AVOIDANCE SYSTEM MALFUNCTIONED AND DID NOT STOP THE VEHICLE TO AVOID THE COLLISION. THE DRIVER SUSTAINED BRUISES TO THE TORSO AREA WHICH REQUIRED MEDICAL TREATMENT. AN OCCUPANT FROM THE 2ND VEHICLE WAS TRANSPORTED TO THE HOSPITAL BY AMBULANCE. NO FURTHER INFORMATION WAS AVAILABLE. A POLICE REPORT WAS TAKEN AT THE SCENE AND THE VEHICLE WAS TOWED AWAY. THE LOCAL DEALER MERCEDES BENZ OF HUNTSVILLE (6220 UNIVERSITY DR.

WHEN THE VEHICLE IS IN MOTION(VARIOUS SPEED, 1 TIME AT HIGHWAY, 2 TIMES LOCAL STREETS), THE FASTEN SEATBELT LIGHT AND AUDIBLE WARNING CAME ON. ALSO, AT THE SAME TIME, THE SEATBELT TENSIONS (PULLS). THE DRIVER SEATBELT WAS FASTENED THE WHOLE TIME WHILE THIS WAS HAPPENING. *TR

WHEN THE VEHICLE IS IN MOTION, OR STILL, THE DRIVER'S SIDE COVER FOR THE SEATBELT/AIRBAG WILL NOT STAY ATTACHED. THIS IS LOCATED ON THE DRIVER'S SEAT AND IS VISIBLE WHEN ENTERING AND EXITING THE CAR. I AM NOT REALLY CONCERNED ABOUT THE COSMETIC ISSUE AS MUCH AS THE SAFETY ISSUE. WITH THE SIDE IMPACT AIRBAGS, THIS IS A SAFETY HAZARD. IF THE BAG DEPLOYS WHO KNOWS WHAT WILL HAPPEN TO THE FLOATING PART? WILL THE AIRBAG, OR SEATBELT EVEN DEPLOY, OR WORK AS IT SHOULD? THIS IS ALSO A SAFETY ISSUE BECAUSE YOU CAN BE INJURED BY THE HARD PLASTIC THAT IS HANGING THERE. THE PIECE CAN ALSO GET CAUGHT UNDER OUR FEET WHILE DRIVING AS IT DOES NOT STAY IN PLACE. I REPORTED THIS THE 3RD DAY AND HAD IT REPAIRED 3 OTHER TIMES. I HAVE HAD MY CAR AND IT HAS BEEN IN PLACE ONLY 5 DAYS IN 2 YEARS, 2 MONTHS AND 30 DAYS. THE NEW LOANER THEY GAVE ME HAD THE SAME ISSUE AND THE PORTERS REPORT THEY NEVER STAY ON. THE CAR WAS IN FOR SERVICE FOR THIS ISSUE 4 TIMES IN THE FIRST 20 MONTHS I OWNED IT. IT COULD HAVE BEEN WEEKLY IF I WOULD HAVE NOT JUST LIVED WITH IT IN BETWEEN SERVICES THAT WERE NEEDED AND TAKEN IT IN AGAIN FOR SERVICE AND THE ISSUE.
