I have had to repeatedly replace front headlight bulbs since a few years after purchasing this car brand new. I questioned service advisor on many occasions and was told they never saw a car go through so many bulbs. I have several service/receipts document this. The bulb rings are now melted on both sides. When I took car to mbz dealer where I purchased and showed them they were perplexed. The service tech stated in front of me and service manager that this was from bulbs installed improperly.. The only place they were ever purchased and installed was this original mb dealership. They looked into it and advised me they would replace headlights for $2200 which was unacceptable to me. Then ran into gm of the 3 dealerships owned and he said he would take care of it for me. He then o

All electrical went out, in motion on city street, then pulled over. Had key in my pocket. Engine stayed running and could not turn off with button or by key. Got out of of car, closed door and could not get back in any door even though driver door was not locked (button up). Engine continued to run until coolant expansion tank exploded. If child would have been in back, would have had to brake window to get in. This is a big safety issue when so many options depend on car's electrical working. Mercedes sail electrical system failed causing over $15,000 in damage cause I was unable to cut engine off. I have sold the car, but believe it's important to have such a safety issue investigated.

The "airmatics-visit workshop" wording came on my screen yesterday on the highway. Hitting the unlock button kicked on suspension as it should and it was sputtering instead of the usual raise noise. It sat overnight and now it sitting pretty low. This is the 2nd time in 6 months the air compressor has gone out. *tr

My door lock would not work, could not even manually open them from the console. Took it in to be repaired, was told that the actuator had fried and melted the unit. It was replaced and within several weeks the "new actuator " also fried. Was told that the computer system would shut it down but the unit continues to run even when the car was turned off! With the unit being in the trunk it's a miracle that the car did not catch on fire. In order to repair this unit, and hopefully they must remove all doors head rest and seats check all vacuum lines to find out which one is leaking, and or replace all vacuum lines, and pray that works, the minimum cost of this is over $5000.00 dollars! Not only is this a fire hazard waiting to blow up, not being able to lock or unlock your doors. The deale

My transmission would not shift out of second gear. I turned it off and back on and it did not clear. I got a "pre-safe unavailable" message. I did some research and learned this is a "transmission control module" failure. It is very unsafe in that the car cannot keep up with traffic and is a danger to myself and others. *tr

In less than a minute it happen again. The engine cut out then started before I could do anything. The third time it cut out complete and stayed off. I was able to move the side of the road and stop and restart the car. It was very scary, all the lights were off and I was on a busy highway at night. It's happen before about a year ago. I mention it to the dealer, they acted as if it was nothing they were aware of. *tr
