My battery keeps draining. When I look at the display screen it only states that the front right light is out. When I had two mechanics look at it and they stated that my battery is being drained due to my seat function not working properly. After not using my battery for hours it dies. I keep having to jump it. My battery has been replaced less than a month ago so I know the battery is not an issue. My display screen gives me a few different malfunctions and than one moment it displays no malfunctions. After charging my car and than leaving it a strange churping sound goes off in my car causing my battery to die again. There are times when my car has died in at night in strange areas and I have to alone and unsafely jump my car and sit until my jumper provides my battery with enough juice to start my car. When I am driving my functions stop working because my battery isn't strong enough to power the everything. This has happened on a number of occasions.

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. Without an operating mfd, the owner cannot view, or certify the correct odometer mileage, required by federal law when selling the vehicle to a dealer or subsequent owner. This is a well-known fault across several Mercedes models. Dealers offer to replace the mfd, at considerable owner expense. However, because of the odometer issue, I believe that Mercedes should fix the display at zero cost to the consumer.

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.

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 !!

After leaving my 2001 clk320 Mercedes at the dealership I was notified that my brake system was defective requiring pads/rotors and other related items along with the fact that every 1000 miles or so, a light bulb or something electrical will fail and I usually find the nearest dealership and get the problem fixed. The brake system (which is not under warranty) was the last straw! we are talking about a 50,000 dollar automobile with only a little over 17,000 miles on it.
