While driving on the highway approximately 70 mph the car stalled. I slowly came to a stop, unable to restart the car. After getting towed to a nearby mercedes service shop, they diagnosed the issue as inaccurate fuel gauge and refueled the car. At the time the car stalled, the tank was approximately 1/8 full according to the gauge, but in fact the car stalled because it ran out of fuel. They were unable to pinpoint why they fuel gauge was showing the wrong level.
We purchased the 2013 gl 550 five months ago. When we were driving home the vehicle shifted itself into park while in was in drive. The vehicle abruptly stopped and violently jerked the car and our family was inside in traffic approaching a four way stop light. When we attempted to put the car back into drive and pull off the car automatically shifted itself into park again while we were driving. This happened in the middle of traffic while making a left turn with oncoming traffic at a light. Police were called. Car was towed. We've since found that there was a recall for faulty installation of the eis for the model year right before ours, 2012. Apparently the problem was never fixed and was passed on, but Mercedes Benz failed to warn consumers nor issue a recall. We are getting no help with repairs even though this is an ongoing safety issues occurring in several of their cars. We're asking nhts for assistance with forcing Mercedes Benz to fix this very dangerous and expensive problem. ## VIN passed ## mercedes-benz 2013 gl 550 ##.
