Turn Signal Problems of Mercedes Benz C320

The turn signal on the front right has been out since about February. The dealer parts guy said quote: "confirmed grounding problem (a design flaw); ground wire is too low a gauge for max current through headlight assy. And overload causes short (meltdown - literally)". I think that when a mbz dealers own people state this fact, and when you can go online and find the same quotes from individuals, over again, then the manufacturer needs to assume responsibility. It is a sad day when a huge auto manufacturer is allowed to get away with an obvious design flaw. My wife & kids are in this car every day ! step up and be responsible mbz !!.

My 2001 mercedes-benz C320's battery was constantly going bad and having to be jumped after not starting it or driving it for approx. 24 hours. Finally, after a certified mercedes mechanic investigated the problem, he informed me that the problem originated from the driver's seat module, which was draining my battery. He informed me that if I unplugged it for the time being, my battery would no longer drain. Sure enough, after unplugging the seat module, I no longer had issues with my battery draining. The seat module controls seat adjustments as well as steering wheel adjustments, so this is very inconvenient, and unsafe, because there are times, when I have to plug the module in adjust my seat or steering wheel, and it does not work, and I'm stuck with the seats or steering wheel in an uncomfortable position. I have also had problems with brake (stop) lights, turn signal lights, etc. , in which the vehicle indicator states that particular lights are malfunctioning, and then after awhile it goes away, and then days later, the lights are inoperable again. I have spent quite a bit of money replacing bulbs. I originally purchased this vehicle in 2004 when it was still under warranty.

Consumer went to start the vehicle and discovered that electrical components such as navigation, radio/cd, telephone, voice command, gas gauges, and power windows were not working. Since then the brake lights and turn signals were replaced twice, and will be replaced the third time in less than a year. Took vehicle to a dealer and contacted mercedes ,who said they could replace navigation and the radio/cd which s\were connected by same computer for $3,000. Dealer did not know why this happened, but there was an electrical short. Have not been replaced or repaired.
