The vehicle involved is a Mercedes-Benz vehicle that experienced severe corrosion and deterioration of the rear subframe component. The subframe is available for inspection upon request and has been identified as unsafe due to excessive rust and structural corrosion. The corrosion created a major safety risk because the subframe supports critical suspension and stability components. The condition could have caused loss of vehicle control, suspension failure, or an accident while driving, placing both myself and other drivers at risk. The problem has been confirmed by a dealership and/or independent repair facility. I was informed that Mercedes-Benz has acknowledged similar rear subframe…

On [XXX], my mother was driving our 2010 Mercedes-Benz GLK 350 to work around 6:30 AM when the vehicle suddenly caught on fire without warning. The car was completely destroyed in the fire. Thankfully, she was able to exit safely. After doing research online, we found many reports of 2010 GLK 350 models catching fire due to fuel system issues and leaks, which appear to be common with this year and model. We were surprised to learn that our VIN currently shows no active recalls, even though the issue seems widespread. We can provide photos of the car before and after the fire, towing documentation, and the police/fire report. The cleanup and towing bills have been expensive, and we are…

Extremely Urgent Safety Warning! Similar to the the passenger fuel filter extended warranty on the passenger side, the driver's side plastic fuel filter pump is obviously visably defective and forming a large crack, thereby leaking a significant amount gasoline into the back seat, with much also draining out the bottom of the vehicle. Additionally, the metal studs securing the filter are painted, making removal of the filter difficult without breaking the studs. No warning lamps or messages.

I just had my vehicle in the shop for starting problem and oil leak. The former mercedes mechanic told me about my subframe having holes in it and the rear wheel moving forward and back during braking. I'm taking it to the dealership for replacement, but I'm upset knowing that I just took a 1400 mile trip with this problem on my vehicle with family in the vehicle and it could have been catastrophic for us all. I've received no notice of the 20 year extended warranty on this vehicle, but a notice of the Takata airbag issue was received recently by me. Not notifying me is irresponsible. I hope everyone gets this repaired before a life is lost.

Corrosión en toda la parte trasera (subframe) que sujeta la suspensión haciendo el carro inestable a la hora de detener el automóvil, y apaga los sistemas ABS,ESP. lo cual lo hace mas peligrosa la conducción. Si Toyota hizo el cambio en sus vehÃculos con por que mercedes benz deberia comprometerse a repara esta parte. Ya que es un riesgo a la seguridad.

Subframe is completely rotted. Taken to several mechanics who were unable to diagnose handling problems and severe tire wear. After research this is a common problem, we were never notified this could be an extremely dangerous and hidden issue. Car is unsafe to operate without expensive repairs. Unacceptable.
