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.

Check Right Tail and Brake Lamps warning light will not go off for months. They are working fine but the light won't go off. Googling on MB World, it shows Mercedes is aware of this problem and a recall is needed to get it corrected being safety issue with warning lights not working properly. See all info. below from owners, conversations and work done by dealers, etc. People note it is a middle school education problem. Please alert me when the recall is confirmed to get this important problem fixed.

I drove my car to get lunch. Came back out to go back to work and the car would not start. Would not even turn over. My Radio did not turn on and I couldn't even roll my windows back up. Luckily they were only cracked open a small amount. My steering wheel cannot be turned, it's locked in it's current position. I am told the ESL (Electronic Steering Lock) and possibly the EIS is the cause of this problem. The display on the dash says "Take your key from ignition" and that is all I get. Had to have my car towed and now I have a dead car with the windows partially open that I cannot close.

Headlight harness on drivers and passenger side is melting and my lights are flickering. I was advised to night drive my vehicle at night, because it could start an electrical fire. This is caused by heat from the lights.

Last week just before Thanksgiving my car of 134,000 miles wouldn't start. Had it towed to my mechanic only to find out like so many others that the Electronic Steering Module(ESL) is 1,500.00 defective. Yet with this being a common issue there is no recall. guess I'm going to a Toyota.

While driving and when parked the headlights flicker on and off. I have no headlights while driving at night, during adverse weather conditions and during dawn hours. I could crash into other drivers, or they could crash into me because they can’t see me. When a parking bulb blows it fuses and melts everything together causing the replacement of the entire headlight unit, this has happened twice.

MY VEHICLE CONTINUOUSLY GIVES ME WARNING/ALERT MESSAGES OF HEADLIGHT/SIGNAL/PARKING LAMP ISSUES.

ELECTRICAL SYSTEM

TURNED IGNITION KEY TO START VEHICLE. NOTHING HAPPENED. NO CRANKING OR CLICKING. COMPLETE SILENCE. STEERING WHEEL AND TRANSMISSION SHIFTER WERE BOTH LOCKED INTO POSITION AND COULD NOT BE MOVED EVEN THOUGH IGNITION WAS IN THE 'ON' POSITION. APPARENTLY THIS IS A COMMON PROBLEM ASSOCIATED WITH A DEFECT IN THE 'ELECTRICAL IGNITION SYSTEM/ELECTRONIC STEERING LOCK (EIS/ESL)' AND IS THE SUBJECT OF A TECHNICAL SERVICE BULLETIN FROM THE MANUFACTURER. THIS CONDITION OCCURRED ON ONE PREVIOUS OCCASION WITHIN THE LAST 45 DAYS. ON BOTH OCCASIONS VEHICLE WAS STATIONARY HOWEVER IF IT WERE OCCUR WHILE MOVING THE STEERING WHEEL WOULD LOCK AND DRIVER WOULD BE UNABLE TO AVOID A COLLISION. THIS IS A WELL DOCUMENTED AND WIDELY KNOWN SAFETY DEFECT FOR WHICH THE MANUFACTURER SHOULD BEAR THE COST OF CORRECTING (AT THE CURRENT TIME VEHICLE OWNERS ARE CHARGED BETWEEN $1200-$1700 TO PERFORM THE DEFECT CORRECTION OUTLINED IN THE MANUFACTURER'S TECHNICAL SERVICE BULLETIN).
