After purchasing the vehicle used from a dealer (with @ 36,000 miles) I started having transmission problems within a year. When I would be stopped on a hill/incline and then accelerate the car would violently jerk (as if I had hit something). It would not go forward until after the sudden jerking motion stopped. It would also behave this way when I backed up a hill or incline. Every year I brought it to the dealer to diagnose and fix it and they told me that they couldn't reproduce it when they had the car, therefore they couldn't find out the problem. I also told them that the engine light would come on and off intermittently, however, they were unable to figure out the problem. Every time I took it in for a service they documented the problem on the estimate sheet. However, this last time I brought it in they were able to diagnose the problem as a faulty transmission. It would slip out of gear when on a hill or slight incline when put into drive or revers from a complete stop. Come to find out when researching these cars that Mercedes have had this problem with their engines for a long time.

Upon acceleration a clunking sound comes from within the transfer case. This vehicle has @ 148,000 mainly highway miles on it. This transfer case problem is a premature failure and is reminiscent of a similar problem Mercedes had @ 12 years ago

On January 8, 2014, the owner of the 2012 Mercedes Benz GL450 was inside her vehicle within the garage of her residence, preparing to leave to perform errands. Realizing she need to attend to her young children, she put the vehicle's electronic transmission into park and was exiting the vehicle when the GL450 suddenly began moving rearward in reverse. The reversing vehicle pinned the owner between the open driver's door and the garage wall, impacting the left side of her body with enough force to fracture her pelvis and bend back the hinges of the driver's side door (see attached photograph. The vehicle then careened out of the garage with her two small children inside the runaway driverless vehicle. Fearing for the safety of her young children who were still in the GL450, the severely injured owner ran down the driveway toward the vehicle and reached it just before it crashed into a gate. Please see attached document for details.

On 01/08/14, a female driver of a 2012 gl 450 was stationary, in the garage, with engine running. Before she exited the vehicle to check on her child in the rear of the vehicle, she pressed the park button on the drive select electronically-controlled column shifter. As she exited and walked around to her child, the transmission suddenly shifted into reverse, the vehicle travelled backwards and pinned her between the open driver's door and the garage wall. Luckily, the vehicle's door hinge bolts broke, the door folded and she was able to extricate herself, as the vehicle continued to travel in reverse until it was stopped by a column at the end of the driveway. The driver sustained massive debilitating injuries. We believe that because of at least two serious engineering mistakes and/or defects, the Mercedes gl 450 drive select electronically-controlled column shifter failed to engage into park. ## VIN passed ## Mercedes-Benz GL450 2012 ##
