2014 MERCEDES-BENZ E550 Complaints

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 should have been covered under the same program as the rear subframe, not be used as an upsell tool to customers affected by that issue. I also believe steel brake lines should just be banned outright for all vehicles, the risk of rupture due to corrosion leading to brake failure is far too high.

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.

Parking brake pedal assembly failed. Yes it's available for inspection. My home is on a hill, a functioning parking brake is required to prevent the vehicle from rolling. Personal mechanic identified issue and replaced part. There were no warning lights or lamps indicating an issue.

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 fire of unknown origin occurred while driving at highway speeds. No accident occurred. Further exploration of the issue from a safe area off of the highway confirmed the following: 1) possible electrical fire emanating from the center speaker of the dashboard 2) center speaker was damaged and appeared melted 3) the only way to stop the fire was to remove the fuse powering the sound amplifier which allowed the car to be driven to the local Mercedes Benz dealer/repair center The car was inspected by the local Mercedes Benz dealer who confirmed: 1) the center speaker was damaged and not repairable 2) the cause of the problem was a "shorted" and otherwise faulty amplifier. 3) the cost to replace the speaker estimated over $400 4) the cost to replace the amplifier estimated over $2700 There are no safety recalls on this particular issue. However, an investigation of the matter on NHTSA and Mercedes Benz user groups has identified numerous occurrences of a similar nature in the 2014 "e" class vehicles. The amplifier, which was confirmed to be the cause of the fire, would appear to have a documentable and reproduceable fault which: 1) presents a safety hazard to owners/drivers of the vehicle, 2) puts other drivers as risk drivers, 3) subjects vehicle occupants to hazardous fumes
