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.

I bought a 2001 mercedes benz C320 vehicle used on 9/19. After taking it home, I noticed while driving the vehicle accelerates on its own without my foot on the petal. I double checked to make sure the cruise control function was off and the vehicle continued to accelerate on its own at a high speed, up to 55mph.when I drive, I am constantly hitting the brakes to keep from colliding with other vehicles. When I put the car in park, the rpms reach 30,000 and the engine sounds like it's accelerating. This IS a safety issue. There are many error codes on this car, so how was the car dealership able to sell this car legally? I need to return this vehicle asap. Please help.

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. *tr

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. *tr

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. *js

While driving on a level and straight road the car automatically applied brakes and came to a complete halt. Weather conditions where; clear visibility, about 85 deg f, dry asphalt surface. Error codes resulting from this fault indicates a faulty esp yaw rate sensor. The independent mechanic code reader showed that the yaw rate sensor output was reading angle rates from as low as 34 to as high as 300+ gradients/sec, while the car was not moving and parked at the shop. As the person responsible for any actions while driving this car, I that the car should not overrule the driver's inputs and create an unsafe condition. The vehicle should just indicate to the driver the existence of an unsafe condition and do not take any action until the driver acknowledges this warning/caution. *tr

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??? *tr

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 !! *tr

On the first occasion (december 16, 2010), my mercedes C320 electrical system shut down the engine while I was driving. the car engine shut off as I was driving 57 mph on the freeway during morning rush hour. there were several cars and tractor trailers behind me when the car shut off as I was driving. the incident was terrifying, as no warning lights (nothing) came on in the car. luckily, other drivers saw me in distress and I was able to maneuver over three lanes of traffic to get to the side strip. the car was towed to phoenix motors (mercedes benz dealership) whereas they indicated an electrical component had gone bad. however, I later learned this diagnosis was incorrect, because seven months later the electrical system shut down again as I was driving. another incident took place where I had no control over the car mobility while driving 60mph on the freeway, because the engine went dead. the electrical system shutting down the engine without warning to the driver can cause a deadly crash. presently (december 21, 2011), my car IS in the hands of phoenix motors again, however, they have yet to determine why the electrical component IS shutting down the engine while driving. I am requesting nhtsa to investigate this matter, because this type of defect has the potential to destroy innocent lives while driving. an electrical component shutting down an engine while driving IS serious and deadly. please, please look into this matter. I was lucky in both incidents, because an angel was watching over me. I could have easy been injured or killed, not to mention others that could have been killed. in both incidents a tow truck was called to tow the vehicle. *kb

- 11007974Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy In advance, observe LI82.10-P-078301 "Headlamps or Front Fog Lamps Leaking or Fogged". 1. Prepare headlamp/check for external damage: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: A headlamp with external damage is not a warranty or goodwill case. 2. Leak test of headlamp with overpressure: Connect test adapter to pressure tester. (Figure 1) Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. Seal all the outlet openings using sealing compound and the given diaphragm with the plunger (picture 3). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged. If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is not leaky and the problem is down to natural physical fogging. If a pressure drop of more than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. Replace any leaky headlamps. Note: Desiccant packs can be installed for headlamps that are not leaky. See: LI82.10-P-064766 Fogged headlamp, desiccant pack installed - open ventilation system LI82.10-P-078304 Fogged headlamp, desiccant pack installed - closed ventilation system
- 11007753Complaint Headlamp or front fog lamp leaky or fogged Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. Headlamps comply with all applicable standards. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps and LED rear lamps: 1. Drive vehicle into workshop (temperature higher than +18 C/+64.4 F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood or trunk. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 C/+64.4F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in the formation of condensation, check the headlamp for a defect. (See Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Remedy 2 A Damaged headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness in accordance with LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. Open ventilation system: LI82.10-P-064766. Closed ventilation system LI82.10-P-078304
- 11005294Complaint Rear lamps fogged up/not leaktight. Cause Fogging of the rear lamps is a natural phenomenon, which can occur under certain climatic conditions. This does not lead to any technical impairment of the rear lamps. Remedy Rear lamp: Remedy 1: Clearing fogged/condensed rear lamps: 1. Drive the vehicle into the workshop (temperature higher than +18 C/+64.4 F) Note: Do not wash the vehicle or subject it to high-pressure cleaning before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the trunk. 4. Switch on the exterior lighting. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation -> a significant reduction in the formation of condensation must be clearly recognizable (defogging progress).
