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.

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.

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.

Replaced the headlight bulbs on my car. The insulation on the 2 wires to the bulb crumbled on both the left and right when I touched the wires. Wiring is defective. This is a safety issue since the wires could touch causing the fuse to blow and cause the headlights to go out while driving at night.

While traveling on the Washington DC beltway in the fast lane, in heavy traffic, the engine completely shut down leaving us stranded in very heavy traffic. Needless to say, this was a very precarious position. Fortunately, police assistance arrived and called a towing service and got us out of harm's way. The problem was diagnosed as a failed crank shaft position sensor. This results in the computer turning off the ignition creating an obviously hazardous situation. I reported this to Mercedes customer service, but they're reaction was that this occurs infrequently, but they were aware that it does happen. So I am notifying you for your information.

The sunroof leaks causing electrical damage. I rarely use the sunroof. Maybe I have used the sunroof 5X. The sunroof should not leak after rare use. The electrical should not be damaged. Apparently, the drains in the sunroof get clogged and the water drains into trunk. This is a design defect. Please investigate. I notice the same issue with many others on line. Thank you.

Driving South on I95 near savannah the dash lights including the brake light lit up on the dashboard and the vehicle began decelerating. Applied the emergency brake and was able to drive the vehicle to the shoulder. After the engine was shut off the vehicle could be started but could not get from park into a gear or even neutral. All four wheels were frozen and so getting the car on to the tow truck was almost impossible. Were towed to the nearest Mercedes dealership where the sbc system was replaced. This took over night as the part was not available at the dealership. Besides being greatly inconvenienced - we had to spend a night in a hotel, we could have been killed if this would have occurred at night. The car was serviced by Mercedes since purchase new in 2004. The part should have been identified during a service call, this obviously was a recall that was kept quiet. Not informing the owners of this potentially deadly issues is a major negligence on Mercedes part.

The ignition switch failed on my 2004 Mercedes E320 wagon which only had 85K miles. If it had failed and just would not work, that would not have been such an issue, however, when it failed it left the engine on requiring me to disconnect the battery to get the car to shut down. Steps to reproduce: 1) put electronic key in car 2) turn key to fully on and start car 3) turn key to off position and remove key from ignition entirely note car is still on and will not shut off even after an hour.

Purchased a new Mercedes Benz, 320E 2004 model. On 2 occasions on the freeway at highway speeds the engine shut down without warning. The engine shut off at once and will not crank when engine has been tried to start again. Had to have vehicle towed. Dealer explained he was unfamiliar with this problem. Thought this may be the computer in the car. Made repairs and replaced parts. About 2 weeks afterwards this happened again. Took back to dealer, and this was corrected. However, was afraid this may happen again. However, has not happened 2-3 months after the repairs. The control module failed. Also, consumer has continuous problems with braking system.
