Recent owner complaints

• Service brakes

  Dealer reports that, in addition to the dangerous corrosion on rear subframe covered by the extended warranty program, the rear brake lines are dangerously corroded and may fail at any time. I inquired about how this is even possible as I am accustomed to vehicles with cupronickel brake lines that do not corrode. I was told they are merely enameled steel on this model and prone to premature corrosion where they are mounted to the chassis with plastic clips that wear off the enamel and allow premature corrosion and eventually catastrophic failure. I was also told the replacement parts are now cupronickel, indicating Mercedes understands the original design was defective. I believe this…

• Air bags

  Both driver and front passenger headrest airbags have deployed for no cause. This is is the second time this has occurred on both sides. No collision occurred in both incidents. First time it occurred under warranty and Mercedes fixed the issue. This time it occurred again and the car is not in warranty. Without functional headrest airbags the safety is greatly compromised for the occupants of the car and can lead to fatal incidents. It seems like a recurring problem with this model as it has occurred twice over 9+ years and both times there was no collision etc.

  I was driving in the Dallas area at highway speed (approx 70mph) during rush-hour traffic when a crackling sound presented in the dashboard area from what appeared to be the sound system (Harmon Kardon surround system). This was immediately followed by the unmistakable smell of burning plastic or something similar. Smoke coming from the center speaker in the dashboard followed subjecting car occupants to potentially hazardous smoke and chemicals resulting from the fire.All signs suggested an electrical fire which was alarming considering this occurred at highway speed. Turning off the sound system did not stop the issue. My safety and that of others on the highway were put at risk because a…

• Rear brake line failureClosed

  On April 10, 2020, NHTSA's Office of Defects Investigation (ODI) received a defect petition from Mr. Surjit Singh alleging premature corrosion of the rear brake lines in his 2013 Mercedes-Benz E350 sedan. The petitioner states that he was recently informed by a Mercedes dealer service department that his car had severely rusted brake lines that need[ed] to be replaced immediately at a cost of about $3300.

The petitioner submitted a complaint to NHTSA…
