2001 Mercedes Benz C320 electrical problems

Filed Jul 17, 2016 · Electrical, Lights · CA

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.

At 55 MPH the front left brake engages without applying the brake pedal and after a few seconds releases, the bas and ESC faults are then visible on the dash. The brake light switch was replaced by mercedes two times, but this condition shows up after a few days of driving , codes show that the yaw rate sensor or connection is at fault. Even when the car is in park with the engine running on a flat level surface the fault warning dash lights ESC and bas will come on with no movement in the car. This is a very dangerous situation for a collision from a vehicle following me and running into me . Many others posted the same problem. Why is there no recall ? I have 8 grandchildren that you should care about.

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 trunk lid would occasionally open up on its own, especially at highway speeds, blocking rear view. This was a major safety hazard. The problem occurred several times over a period of one-two months.

Power control seat & steering column module/regulator went out & before it did it use to drain the battery where car wouldn't start if sat for less than 24hrs, so had to unplug but now the entire system doesn't work plugged in. I can barely reach the pedals to drive properly, this is a safety hazard & needs to be a recall. It also needs to be a way to manually adjust. Thank you

I purchased this car as a graduation present for my daughter. I know it's and older model, and has high mileage, so I expected some issues. However, after reading several post across the internet it seems as if the seat module issue is a problem. Everytime she lets the car sit for more than a day, it won't start. She has to jump start the car, and this seems to be an issue across the board that benz should have recalled by now. This is a major issue and something needs to be done. This morning the card once again would not start. I have contacted the dealer and benz direct, but they will not recall the car for this issue, they just want you to pay to have it repaired. With so many people having the same problem why has this car not been recalled???
