2014 MERCEDES-BENZ E350 Complaints

I am losing brake fluid. Likely from rotted brake lines. Was given a quote attached below for repair of rotten brake lines 2 years ago. My friend has the same vehicle (a 2014 model) and had to replace brake lines for the same issue. I've never heard of break lines rotting and leaking on another make of vehicle after only 8 years of use at 70K. The car is always garaged, washed weekly and currently at 91K miles. I believe the coverage of the rear subframe should be extended to the break lines for this model of vehicle since it is a commonly reported problem per the dealer.

The contact owns a 2014 Mercedes-Benz E350. The contact stated that while the vehicle was at an independent mechanic for an oil change, the contact was informed that the rear driver's side control arm was severely corroded and had detached from the subframe. The contact was also informed that the failure caused premature tire wear on both rear tires. The vehicle was then towed to the dealer, where it was determined that the subframe and rear driver's side control arm needed to be replaced. The vehicle was not yet repaired and remained at the dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 110,000.

My 2014 Mercedes started getting a fault light with multiple performance issues. Mercedes dealer where I can carry out my routine maintenance diagnosed the issue to the electrical harness being contaminated with engine oil and it needed to be replaced on the engine because of a known issue whereby oil from the upper camshaft sensors seep into the harness and makes its way to ECU and causes possible failure of the engine control, which could lead to shutting down or worse, incorrect engine timing which would lead to incorrect detonation at the compressors and subsequently engine failure at critical operational phase. This below link and attached document describes the issue well. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2014 Mercedes-Benz E350. The contact stated while driving 50-55 MPH and depressing the brake pedal, the brake pedal went down to the floorboard and the vehicle failed to respond as needed, causing a stopping distance delay. The message "Low Brake Fluid" was displayed. The vehicle was taken to an independent mechanic, where it was diagnosed that the rear metal brake tubes were corroded, which caused brake fluid to leak. The mechanic replaced the rear brake tubes. The vehicle was repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 59,000. The VIN was not available.

The contact owns a 2014 Mercedes-Benz E350. The contact stated that while attempting to accelerate, the vehicle was shaking abnormally. There were no warning lights illuminated.

The vehicle was also taken to the dealer, and it was assumed that the failure might be related to the transmission; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 40,000.

Rear brake lines are rusting out prematurely caused by a defective rear sub frame

RE: VIN# [XXX] I am the owner of the above referenced vehicle, a 2014 E350 4matic sedan, showing 98,000 miles on the odometer. On Friday [XXX] I was alerted by Mercedes Benz of Portsmouth, NH that the rear brake line on my vehicle had ruptured. I asked if I could see the failure, and they were happy to show me. I was dismayed at what I saw and took photos which I have included here. The extensive amount of corrosion was shocking. I also own a 2003 chevy plow truck that was driven on salt covered roads that did not require brake line repair for 18 years. I would not expect brake hardline failure at 9 years for a Mercedes product. Disappointed that my car was not able to be driven, I asked for a price for the repair. It was explained to me that Mercedes could not repair just the area of the failure, but instead had to replace the entire line. I understood this as the line was impaired in other areas as well, and posed a safety issue. The quote for the repair was $3,500.00 dollars. The quote represented approximately one third of the vehicle's value, I opted to have it towed and repaired the failed sections myself. (photos of cutout failed sections enclosed here). The car is now drivable, however the remainder of the hardline is still very corroded in other areas of the vehicle. Because of this I would respectfully ask that Mercedes Benz please correct this ongoing safety issue at their cost. Thank you for your consideration in this matter.

I’m getting a pre-safe inoperative message on my dashboard all the time, the Mercedes dealership is telling me the driver side seat belt needs to be replaced. This is a safety issue. This vehicle has 40,000 miles on it and it’s a family car that was extremely expensive this is unacceptable, Mercedes should pay for the seat belt replacement.

My vehicle is having the same issue as follows in quotes from a Mercedes recall Campaign No.2017020018 (attached) : Replace Steering Column Module. Here is the description of the problem from that Mercedes recall "This Recall Campaign has been initiated because Daimler AG (‘DAG’), the manufacturer of Mercedes-Benz vehicles, has determined that on certain E-Class vehicles (213 platform) the column-mounted shift lever module might become inoperative due to possible damage to the internal circuit board. As a result, the vehicle might not move forward or rearward with the shift lever as selected by the driver. However, both the auto-P function and automatic parking brake will continue to operate as intended and prevent the vehicle from moving forward or rearward. If the vehicle does not move forward or rearward with the shift lever as selected by the driver, there is an increased risk of a crash" In my own words, on an intermittent basis, I could be in reverse, move the steering column shifter to drive, but the vehicle remains in reverse. Or, I could be in drive, put the steering column shifter in reverse, but the vehicle remains in drive. This problem is intermittent. It could happen many times in one day, and then not happen again for many weeks.
