2014 MERCEDES-BENZ E350 Complaints

Electrical burning smell and buzzing coming from car entertainment system speakers. Did not stop even when entertainment system was turned off. Had engineer diagnose and issue is the rear subwoofer. Had to remove fuse or disconnect cables to stop issue.

Car control was diminished and braking caused car to pull hard. Creaking noise from rear end. Removed rear wheel to find frame had perforation where rear wheel has linkage to frame.

Motor mounts and transmission mounts continue to fail at intervals or 13,000 miles and again at 16,000 miles. Vibration of transmission is scary. Mercedes has replaced the mounts many times. They refuse to install new Transmission mount now after only 16,000 miles on the replacement. I have contacted MBUSA and they are telling me , they will not help with these substandard parts. Very well-known issue.

My electric power steering failed. It often resets and can be unpredictable when it wants to fail again. It’s an intermittent problem that local dealer tried to fix with a software update but did not work. I was told I need a new steering rack at $5-6k which is unacceptable for any vehicle that has been maintained it’s whole life . My car is 8 years old with 100,000 miles with full service records I feel like this is a premature failure of the electric power steering

The rear subframe of my vehicle failed at the lower trailing arm mounting point (passenger side). This resulted in the car swerving to the right when I applied pressure to the brake pedal, which was worse at higher speeds. This had been getting progressively worse for a few weeks until I almost spun out on the highway while braking. The next day, I randomly got a flat tire on the rear right side while driving at 30MPH near Valley Street in Providence. There were no warning lamps or messages prior to the failure. I immediately replaced the tire and brought it to Midas on Mineral Spring Ave in North Providence, RI, so that they could inspect the vehicle. They discovered that the rear subframe was almost completely disconnected at the lower trailing arm mounting point due to excessive rust that had wore a hole in the part from the inside-out, which was not visible at the time of the last inspection. Midas immediately informed me that the car was unsafe to drive more than the distance back to my house. They also informed me that 3 tires needed to be replaced, including the flat, as a result of excessive wear on the inner wall and the inner edge of the tread. None of these three tires had reached the wear bars yet, and Midas confirmed they would not have had to be replaced if not for the subframe defect. I had the car towed to Mercedes-Benz of Warwick after Midas replaced the 3 tires (RL, RR, FR) because I heard that Mercedes had recently extended the warranty period for rear subframes (only months after a class action lawsuit was filed about the issue). Mercedes inspected the vehicle and confirmed the issue, and is currently replacing the rear subframe under the new extended warranty program for rear subframes. However, they refuse to reimburse me for the other issues directly caused by the corroded rear subframe (which they admit liability for when they replace the part free of charge), stating they have been instructed by corporate that related issues are not covered.

The contact owns a 2014 Mercedes-Benz E350. The contact stated that the vehicle was taken to an independent mechanic who informed the contact that the brake lines were extremely rusted. The contact related the failure to NHTSA Action Number: DP20004. The vehicle was taken to the dealer; however, the vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 126,000.

Power steering went out while driving/malfunctioned. This apparently affects other E-Class models, but mine is not among those listed in the recall.

The contact owns a 2014 Mercedes-Benz E350. The contact stated that the parking brake release failed to release as needed. The failure recurred several times however, the contact could not recall how the parking brake was released. On one occasion AAA released the parking brake however, the contact was unsure how the AAA mechanic was able to release the parking brake. The contact took the vehicle to a certified mechanic who diagnosed the vehicle and determined that the parking brake, and the brake cable had failed to disengage as designed and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure but had not yet responded. The approximate failure mileage was 36,400.

I notice a strong smell of gas inside my vehicle immensing from the back seat area of my car.and it's stronger everytime bi fill up the gas cap is placed back correctly and no top off ever

The vehicle was inspected during an alignment at a dealership. The sub-frame has rotted out. The car was swaying to the side. I believe this car is dangerous to drive. The repairs are around $5000.00 dollars. There should be a recall on this Mercedes Benz E-Class 350 SUB-FRAMES. It is not safe to be on the road. The dealer is no longer around. The manufacture of this car and so many other Mercedes Benz with the ROTTEN RUSTED SUB-FRAMES should be held responsible to pay for the damages and or replacements. Before someone DIES on the road. A recall for this vehicle needs to be done ASAP! Please HELP! I have a picture of the rotted sub-frame and paperwork .Not sure how to upload Why are other countries recall for free and not the USA?
