What owners said

2004 Mercedes Benz E320 Rockville, MD

ELECTRICAL SYSTEM

The sunroof has a recall due to the fact that it has a bad seal, which could fly off due to this issue. I know the seal is bad because the whole roof leaked a few years ago and fried all the electronic; e.g. lights, sunroof controls, trunk light controls, side door controls. I went to the dealership and they said they would not fix it because they could not open the sunroof to see the manufacturer date on it.

2004 Mercedes Benz E320 Palm Desert, CA

ELECTRICAL SYSTEM

The TRUNK will not open. It is supposed to open by pressing the button on the key fob or taking the thin key out of the key fob and manually open the truck with the keyed lock. Neither method works. There is absolutely no way to open the trunk otherwise (i.e. inside button or lever). When the key fob button and the thin key do not work there is absolutely no way to open the truck. There is no way to access the lock from the trunk lid rear and there is no way to access the trunk from behind the back seat cushions. It is a very bad situation and dangerous.

1997 Mercedes Benz E320 San Jose, CA

ELECTRICAL SYSTEM

Driver seatbelt exploded while buckled up as the car was going about 30 mph on a 4 lane street. No warning and was very traumatic. I had to pull over when I smelled something burning. When I released seatbelt to get out of the car it would not buckle up when I tried to get back in the seat. Had to drive home without seatbelt on Christmas Eve. The same thing happened a month later to the passenger seatbelt when I was a passenger in my car. This was very traumatic while driving down a 4 lane Avenue.

Everytime I get in my car, the battery is dead! I have purchased several brand new batteries, and the same thing! I purchased a new battery, and my wife and I went on vacation, and as we was headed back home, we began to smell a real foul oder! We stop to the gas station, and looked everywhere, but didn't see anything! As we continue to drive, and turned in the drive way the battery light came on! I opened the trunk, and there was the foul smell, and the battery was so hot it could have caught fire, luckily we was home

2004 Mercedes Benz E320 Atlanta, GA

ELECTRICAL SYSTEM

The vehicle will flood after being exposed to rain which has caused all sorts of electrical issues. I have read online where several others have filed lawsuits regarding E class Mercedes for similar issues. The car’s interior will take on water and since there’s several electrical components running along the floor board of the car they will become damaged and cause the car’s computers and electrical system to go crazy. I picked up my car from having the oil changed at a local service shop a few days after it was repaired and I was driving back home after the service pick up and the car completely lost power. I got out of the car and opened the trunk in which I had to do so by using the key inside of the key fob. When I opened the trunk, I noticed that there was a little bit of water in the trunk which led me to open the back door and to my surprise there was standing water behind the driver seat. I checked the driver floor and it was soaked as well. I had the car towed back to the shop where I had the oil changed and the owner did not have the available equipment to test the car. I dried the car out over the next several days and drove to a local Mercedes dealership where they told me to do a full diagnostic on the car it would cost upwards of $19k. Are you kidding me? Now I know from reading others stories that this isn’t an unknown issue. So, what do I do now…file an insurance claim? I guess that would be the next step but they’ll turn around and get the money right back out of me by raising my policy rates. This is terrible. My car is a 2004 E320 with just under 65k miles on it.
