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.
