2001 Mercedes-Benz C320 Exterior lighting Problems

“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. …”

“I had a few electrical problems but have now been resolved through many repair shop visits. I have 109,000 miles on the car. Now. The issue that kept occurring is the passenger door handle that keeps coming off. I already replaced it once and the part itself is $350. I can buy the whole door for $300 at the scrap yard. Not sure what to do. I feel like its the glue and maybe the hot humid weather is affecting it? I did have to replace a new battery and thought something was wrong with the car because it drained so quickly. I think the battery was just bad and its been fine ever since.”

“The multi function display (mfd) screen in the dash fades with interior heat (in summer) and eventually fails over time. The mfd displays all critical vehicle operation information (such as coolant temperature warnings, electronic stability control activation, etc.), and all notification of vehicle fault codes that occur. Without the information visible, the owner can't know if there is a safety problem. There are no mechanical gauges serving as back-up. Further, the vehicle odometer is only visible in the mfd. …”

“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. …”

“Dt: 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.”
