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.

Suddenly the vehicle trunk does not open, tried both remote key & door trunk latch. Got a message on panel regarding 3rd brake light..unable to get the wheelchair from trunk but drove car around the block and was then able to open it using my key remote. Then a few minutes later again was not able to open the trunk, but now the panel read license plate right and left light lamps not working...night driving is an issue now...ca laws require lic plate be lit and visible at all times. I went online and noticed all the buzz and complaints reporting this same issue regarding brown wire being severed on many makes, models and years on mer Benz vehicles. I E-mailed mb customer service to ask about a recall and they do not have one to my surprise. Got a call today from [xxx] @ [xxx] stating there is nothing mb can do since my warranty has expired...I advised him I have under 50K miles on this car, he said that I would need to get a diagnostic test costing me over $100 in order to find out what the problem is plus according to internet comments this is a $250 or more repair cost. I explained my internet findings and he again apologized, said there is nothing he can do for me. I explained my concerns and feel that mb should step up and take responsibility in good faith and good customer service and fix this issue at their expense, obviously it is an electrical issue mal-function and they are responsible for fixing the problem and should not put this burden and expense on their customer's. frustrated mb customer

The right rear tail light is out do to bad original electric wiring and connectors. The problem is common and widely known and they've recalled for C-class but not for E-class. Brake light won't function because connector has melted. Potential fire waiting to happen now.

My wife was driving when she smelled something burning and then felt something burning, she pulled over and jumped out to check and found the seat warmer had malfunctioned and burned through the back portion of the seat. Her shirt had a slight burn to it and smoke covered interior of the car. The hole in the seat is about the size of a cigarette burn but deeper. She took it to the import repair shop who disconnected the power source wire to the seat heater for safety.

I was using the warming seats and had pulled up to the post office to drop a letter in the box. The letter had fallen to the ground. I got out and placed the letter in the box. I got back in the car and pulled up to keep from holding up traffic while I had replaced my seat belt. A SUV had crossed my path when I smelled something burning. I assumed it was exhaust from the SUV. I was about to pull off the parking lot when I noticed thick white smoking coming from my seat. I immediately turned off the seat warmer. The smoke dissipated afterwards.I continued to drive the car about 1/2mile to the grocery store. I got out and noticed a burn on seat.

I was driving home from work on a freeway traveling at about 65mph. All of sudden, my car starting to slow and decelerated which I pulled my ehicle over to the emergency lane where it stalled. The car wouldn't start after that and I can smell the burning from the under the hood. I got it towed to a Mercedes specialist shop. The shop reported that there was a fire inside the air intake manifold that caused damage to other components as well which was very unusual. This manifold component was all burned and melted inside including other surrounding components. I consulted with the Mercedes dealership which they stated this never happen to any Mercedes models so I think this is a defect and a safety hazard. This is only a 5 year old certified pre-owned purchase made from the dealer 3 years ago when vehicle had only 38,000 miles on it. Unfortunately, my warrantly just expired 5 months ago. At this point, the damage so far exceeded $4,000 to repair and the dealership won't do offer any goodwill repair on it. Luckily for me I was not injure from this incident but it may not be so lucky if it happen to someone else.

Turned drivers seat heat feature on, after a few minutes I smelled burning. Mercedes just repaired A/C (3 visits) so turned off the A/C. next think I know smoke is coming from drivers seat, my 3yr old riding in her car seat "installed" behind me. Heater in drivers seat was burning, with the air no longer blowing, smoke was now visible. I had to cross 3 lanes of traffic to pull over. The "fire" burned a hole through the leather seat to my jeans leaving me a slight burn. Car towed to Mercedes.
