“The vehicle slips into neutral and says 4 matic not available. I have to coast to a stop and then shutoff the vehicle, turn it off and then restart it. Also the forward collision warning alerts when I pass underneath a large metal freeway signage.”

“I had two mva accidents (february 1 and march 16, 2016) in this vehicle within~ 3 months of ownership. The accidents occurred when I slowed down this vehicle under 10-15mph. Upon purchase, I noticed unlike other cars I have owned, at a stop this mbgla 250 vehicle engine would cut off completely and start back when the gas pedal was pressed. I was told by the dealership this was normal. …”

“Transmission violently engage in reverse: so far I have only experienced this (twice) during cold-starts. Started the engine, shift car in to reverse gear, disengage parking break. In normal situation, the car would reverse slowly without applying throttle. In the two times I experinced the problem, the car would still be idle, even after gently applying throttle. After about 5 seconds or so, the car would violently jerk and the transmission finally engaged in reverse. The local mb service center was not able to diagnose the issue. …”

“It appears that when the turbocharger is engaged, coolant leaving the turbocharger is spraying from where a presumably now missing clamp would otherwise form a tight fit around the tubing, which is normally housed beneath heat shielding. The heat shielding has been displaced by the high pressure produced by the hot liquid. The liquid is so hot leaving the turbocharger that as it sprays out onto the surrounding areas it has melted the air intake system.”

“Upon start, got a reverse not possible warning. Tried to drive home, but shifting was very erratic and car slowed dramatically between shifts. On several occasions, cars behind me had to swerve to avoid me. And, if I would have had to reverse out of danger, I would have been in serious trouble. After too many close calls, I stopped to arrange a tow. When I returned to the car to move it, the problem went away. I am afraid to put my family in this car.”
