Spent over $2k just on diagnosis and wrong fixes. It started with problems cranking. I replaced the key fob, replaced the battery, replaced the alternator, have had mercedes diagnose with no answers. My usual mechanic diagnose with no answers. A european speacialist replaced the alternator and tensioner pulley. Took it to a friend and we discovered that there was a leak in the sunroof running down the side of the car into the battery compartment. At this point various problems are going on. The windows, door locks, radio, cranking, all intermittent but not always at the same time. Took it to another mechanic who said the sans module is bad, at least. An $800 fix, then they could move to the next module and the next. Also maybe unrelated but maybe not. Low car light came on. Engine 'died' (vehicle lost all power) while traveling at highway speed or will jerk down gears and only continue to function in drive @ 40mph or lower. I had to pull vehicle over on side of the road with no power assistance steering or braking. This problem occurred with no warning and at highway speeds creating an immense safety risk. Many others have reported the same issue with this and related cars for this and nearby model years. Like them, I wonder why there is no recall. Mercedes benz will not replace these defective parts willingly and there are many of these cars driving down our highways placing not only the passengers at risk but other drivers around them.

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.

On the ntigh of april 15, 2019, while driving on a street in orlando, fl, the warning that the driver side low beam was out came on. I replaced the bulb the next day but the new bulb lasted about 20 minutes and the warning came on again. Thinking I had a bad bulb, on april 17, 2019, I went in again to replace it. This time I noticed a good quantity of fragments of dried up wire insulation inside headlight housing and noticed that the 3 wires leading to the bulb were bare. The wires are shorting out, the new bulb did not last. I did a brief internet search and concluded that this is a common safety problem with the e350 and mercedes is aware of it. The wiring insulation is not suited for the job; it is failing; it could cause a fire or a crash if both headlights go out at once! Therefore I am reporting this issue and expect to see mercedes stepping up and taking ownership of this problem.

The warning light saying my low beam bulb is blowed. The car was stationary at moment. I had the bulb replaced and it still did not work. So mechanic checked and saw pieces of wire within the headlight casing. Electrical wiring to my headlights is disintegrated. So I assume; the complete wiring throughout the engine is disintegrated. So I begin searching online and read the issue with mercedes using faulty wiring. Therefore; I am reporting the issue and want some type of solution.

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.
