Vehicle began shaking on the highway. It was coming from under the front hood and was shaking the steering wheel. The check engine light came on. I pulled over and had it towed to the Mercedes repair shop. They said it was related to a bad balance shaft and that it was a systemic problem with the engine in certain Mercedes e350s. I was told I needed to replace the camshaft and it would cost $6,000!!! After some research, it looks like Mercedes agreed, back in 2015, to cover only certain of these Mercedes, but there was no recall. I could have been killed if I was rear ended.

My vehicle shut off while I was driving on a main street. Two minutes later I could start it. Then next day I could so I took it to a trusted mechanic and was informed about recall. It hasn't started since. The mechanic isn't certain about exactly the problem but said there was some misfires on sensors. Unknown exactly what's wrong. I did get a letter in the mail about a recall offered to me if similar conditions happen.

The engine stalled while in motion and driving over 45 mph. This is the 2nd time this has occurred. Both times I was travelling over 45 mph on a large and busy city street and had difficulty steering my car to safety. There are no codes to explain what might be the cause. Replaced the transmission control unit the first time. After removing the key, putting the car in park and waiting for 5-10 minutes, in both occurrences I was able to restart the vehicle and drive to the dealership, which was less than 5 miles from my location.

At about 87,000 miles, the car is essentially useless because of a known defect. The balance shaft, engine intake manifold and transmission conductor plate need to be replaced. Mercedes will not take responsibility even though there was a class action lawsuit.

Upon filling up gas tank you can smell gas around the rear of the vehicle. This happens for the first day or two after filling up and then becomes less and less over time until you fill up again. There is a much stronger smell when inside an enclosed garage and I am worried about the fumes being ignited by a water heater Pilot flame.

While driving on freeway, engine suddenly revved high and almost red-lined on RPM gauge. Exited freeway and RPM (while lowered) was still high. A 3rd party mechanic diagnosed transmission valve body failure and advised on replacement. This must be a a known issue because mechanic asked that in order to replace the part a valid personal id must be recorded as part of the parts replacement per Mercedes.

30 Aug.16 took my 07 E350 with 29427 miles to the dealership because the check engine light came on and the car was hard starting. After arriving I informed the service writer the car had shut down while driving. We were proceeding through a busy major intersection when the car shut down. Luckily it started so we could safely exit the busy major intersection. After a diagnostic test was ran, I was informed the crankshaft hall sensor was defective. Additionally, the engine control unit, engine wiring harness, crank sensor and various other components are oil soaked. I notified Mercedes Benz to be told the car was out of warranty. Mercedes Benz should be held accountable for the unsafe defective materials they use. The above issues are a danger to the occupants and general public as well. The defective oil soaked wiring harness is can cause a fire. The car shuts down while driving is dangerous.
