2012 MERCEDES-BENZ GLK350 Complaints

On August 17, 2025 I rearended a vehicle in front of me who jammed on their brakes for no apparent reason. We were the only two vehicles in the area. Upon impact, the following airbags deployed....steering wheel, driver knee airbag. I sustained injuries to my lower extremities from the exploded knee airbag which contained metal components that impaled my skin. I continue to receive treatment for multiple injuries and the wounds that have not healed. My safety was at risk due to the metal components (shrapnel) deployed via the exploded knee airbag. I also sustained injuries my left wrist from the steering wheel airbag, and my left chest from the tightening of the seatbelt. The local Mercedes Benz dealer recently towed the vehicle from my home address to their facility for inspection of said airbags. As of today, I have not received any report from MBUSA.

I brought my car in to my local mechanic and was told my rear suspension was corroded. He said it would cost around five thousand dollars to repair. I researched online and found mercedes did not have a recall but has extended the warranty and will cover the repair to the rear suspension. The mercedes dealer called me and told me my brake lines were rusted out and needed replacement and that it was not covered by the extended warranty and would cost thirty five hundred dollars. In all my years of driving, I have never had the brake lines rust out on a vehicle and can't imagine that this is not related to the suspension issue. I have done some research and seen many mercedes owners have had the same complaint. I believe mercedes benz should be responsible for this repair just like they are responsible for the corrosion with the rear suspension.

My passenger got 2 degree burns to his right buttocks and seat is melted ...he is a paralyzed patient i took him to the er and the burn center i have pictures and documentation....my guess the seat got to hot melted and burned him this what doctors concluded the is very scary for a seat to burn the skin off your butt

The seats on both the passenger and driver size has split at the seams. They began to appear in 2012. The battery failed and the car would not start. Periodically the car starts up slow. The car bucks in a hard motion when trying to accelerate. The car makes a grinding noise, with a dragging feeling, while driving. Mechanics cannot figure out what or where the sound and feeling is coming from.

Electronic steering wheel lock is broken and engine will not start because of lock.

I smelled gasoline in my car didn’t think of anything . Till today when i pumped gas it smelled very strong got home parked my car i notice a leak i look closer under and it’s leaking gas .just got this car 2 months ago There was a safety recall about this issue back in 2013 and I was not sure if this issue was corrected before on my vehicle and think this needs to be recalled again. Please investigate

RUPTURE OF LEFT REAR AND LEFT FRONT BRAKE LINES 1/26/24,8/30/24. BOTH TIMES THE FAILURE WAS UNANNOUNCED WHILE DRIVING THE CAR AND PUT MY LIFE IN DANGER.

My rear subframe is rotted out but won't be replaced under warranty because there are no rust holes in the metal. The rust is very extensive, and the car isn't safe to drive. The rear metal brake lines are also rotten and need to be replaced. I've owned many cars older than this one with more miles, and I've never had rusted-out brake lines. This is a safety issue.

I smell gasoline every time I fill up the gas tank and don't smell it when not quite full. I haven't check yet but I think that the fuel pump flange has deteriorated. My co-worker has the same exact issue and he found out that it was the fuel pump flange. There was a safety recall about this issue back in 2013 and I was not sure if this issue was corrected before on my vehicle and think this needs to be recalled again. Please investigate. Thank you. Sincerely,
