While driving the car on [XXX] at 9pm on sunday, [XXX] in lane two during a heavy rain a audible clicking noise came from the drivers side front of the dash instrument cluster area and all of the lights on the car simultaneously turned off without ever touching the light switch i was unable to see the road in front of the vehicle also the windshield wipers quit working and the radio and navigation display went off and closed and opened and closed( turned off and then on and off again) the instrument cluster went dark as well, luckily i was able to turn the steering and apply the brakes and steer the vehicle onto the shoulder of the road and come to a complete stop after several attempts to turn the headlights back on i determined that the vehicle was not safe to drive , and had the vehicle towed to a reputable mechanic, and upon diagnosis he contacted me and stated that the drivers side front signal acquisition module A. K. A. the (sam) module had failed due to water intrusion into the fuse panel sam module area , the mechanic stated that i should file an incident /complaint form with your office , upon searching the MERCEDES BENZ forums and sites on the www i found many customers with a broad range of models (w204)approximately this same year model have identical complaints and nothing has been done by MB usa to remedy the problem, i believe this matter to be a major safety concern and i am wondering why this matter hasnt been taken into consideration by your agency and by MB usa as a safety recall to replace the failing modules and retrofit the fuse panel sam module area to prevent water intrusion thats causing the obvious safety concern and possible liability on the part of the MB/ DAIMLER corporation. it seems this is clearly a problem and it needs fixed we are terrified to drive the vehicle for fear of a repeat incident. Sincerely the [XXX] family INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2008 mercedes c300 with bad esl. Cost to fix is $1200. Seems like this is a known issues with mercedes as an internet search leads to many other who have had the same issue. I parked the car at work, then went out several hours later to go to lunch and it would not start. There was no sound of the starter or any other noises when trying to start the car. I thought it was the battery, but all the lights and everything else electrical worked on the car. Just to be safe, tried to jump the car, but it still did not start. Car was stuck and could not shift it into neutral. Had to call a tow truck to get it towed my local mbz dealer. Turns out it has a bad esl.

When I've got to the car, put the key in the ignition, and turn the key with no crank noise in the engine. After a lot of tries I had noticed that my steering was not unlocking, windows don't work no lights on like ABS, check engine or all the lights that come on with the key on the on position, and that the car would not shift in neutral. After trying to jump the car and rearming/disarming the alarm I checked on line and found out that a lot of people have the same problem with their mercedes. Here is what I experienced 1.put key into ignition, steering wheel doesn't unlock. 2.instument cluster displays "remove key from ignition". 3.turn key to accessory, no lights on dashboard, only the radio works, windows don't work. 4.turn key all the way to start car, nothing happens.

On 12/15/15 my car did not start due to "SRS" warning on the display. I had to tow my car to mercedes dealer. They have fixed the issue blaming on battery but my battery was fine all the lights were coming up. Later same week I have received mail from mercedes regarding to a recall due to SRS malfunction. Even though dealer new the SRS problem they have charged me $300+ labor for it. I would like to get my towing and labor fee which they fraudulently charged for.

2nd time with same eis issue in one year. Ignition would not turn over but all lights, radio, etc were working just fine. It cost me $1300 to get it fixed the first time after having it towed to a dealership. Was not covered by warranty. A year later I have to do it all over again?!?! It is ridiculous that mercedes does not recall this issue as it is so common after reading so many posts about it.

Upon entering my vehicle after pumping gas late one evening, I proceeded to turn the key in the ignition and the key would not allow the car to start. All the lights on the dash, radio and headlights were operative at that time. I attempted a jump start to no avail. I proceeded with having he vehicle towed to a local dealer where it was determined that there was an issue with the electrical steering/ignition system that was electrical in nature and "common" for the year and model of the car. If this potential defect is common then it is "known" to the manufacturer and its dealers who can be held strictly liable or any manufacturing or design defect, or inadequate warning. That being said, if the product is defective, what prevents the recurrence of the issue after replacement of the part, which would essentially be replacing it with another defective part. This matter is serious to the consumer, and the manufacture could easily reduce the risk of harm to its consumers by altering the design in a much more cost effective manner than allowing its consumers to bear the costs of its manufacturing error.

Prior to pulling into my garage, I smelled burning electrical wiring. All warning lights on the dash panel for the left rear lights came on. I opened the trunk to see if a light bulb burned out, and smelled the burning wires. Opening the panel covering the left rear lights, I saw a burn through scorched circuit board. On closer examination, I noticed the ground wire was thin and the cause of the severally overheated and partially melted area on the left rear lamp assembly. Since then, the mercedes dealer replaced the circuit at my expense. About six months ago, the same thing happened on the right rear tail light assembly. It was also a thin ground wire that had overheated and partially melted the circuit board.
