What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The seatbelt engaged and I was worried for my 10 month old in the backseat. I had to come to a complete stop to regain control. A passerby stopped and said it looked like the car lifted 2 feet in the air. After restarting the car multiple times the air suspension has not recallibrated. My back and neck are sore.
The seat warmer was turned on and the seat caught fire. Smoke filled the cabin of the car. The result was a hole in the seat of the car.
2007 lost all electrical power and the engine stalled while being driven. The power comes back on in 10 to 20 seconds and the car can be restarted. This happened 3 times during the first 10 days of oct 2009 when the mileage was just under 30,000.
Dramatic explosive failure of the right adaptive suspension strut airbag while vehicle was standing in the driveway with the engine on. The vehicle was towed to a dealership service department where the strut was replaced and the failed part was returned to mbusa for inspection.
On the 2007-2008 mercedes gl the driver and passenger side ac vent closest to the side windows allows air to be directed the vent on the door (which should be used for defrost only); this then fogs up the side windows, making it impossible to see the side mirrors whenever the ac is on.
