Our 2006 mercedes ml500 has had both internal mechanical latches to doors break apart inside the front doors at different times. what happens IS that when use use the electronic switch to open the vehicle doors, they unlock ok but the door will not close or lock after initial opening. when this happens, you cannot close the door (the latch IS broken). this IS a life threatening problem if you have to drive any distance to get to a mercedes dealer. of course they never have the parts in stock. on one occasion, I had to try to physically hold the passengers side front door closed until we could get some rope to tie from one door to another. fortunately we now have a rope in the car at all times. my wife was alone in the vehicle yesterday and had to tie the divers door to the front passenger door. fortunately she works 1 1/2 mile from the local mercedes dealer. it was still very scary for her because whenever she turned a corner, the driver's door would swing open slightly. again this IS a dangerous problem and IS a $1,000.00 repair. The last time this happened was about a year ago.
- Exterior lighting
The rear brake lights sockets are getting burnt causing the brakes light to fail. Corrosion on a connector can cause the tail, brake or rear turn signal lights to dim or fail. This IS a safety issue because it can make cars less visible to other drivers, which can increase the risk of a crash. This IS the exact same issue with the 2008 - 2011 mercedes c class which recently had a recall issued.

Sporadically, while driving along on local roads or the highway, the car's transmission does not switch higher than third gear. The problem occurs about once a month. upon engine restart, vehicle drives properly. my pedal shifters do not work when this problem occurs; I can try to shift gears with the pedal shifters, and the software indicates a change from 3RD to 4TH gear, but the actual transmission does not change gears. it remains stuck in third gear whether I speed up or slow down. if I place the vehicle in park and try to reverse, there IS no power to the vehicle until I restart the car. this seems to be occurring with more and more frequency. I have a safety concern that I have to pull off the road and restart my car whenever this occurs. this seems to be problematic for several owners on the nhtsa site and online. *Jb

2006 mercedes benz ML 500. consumer writes in regards to vehicle electrical issues. *smd the consumer stated he saw on the news there was a potential recall on the c class mercedes benz due to electrical issues in the rear tail lights which short out and catch fire. The consumer stated he had the same issue with his vehicle. Two years ago, the entire rear tail light compartment, wiring and bulbs had to be replaced, due to corrosion. Shortly after the replacement of the tail lights, the lock on the tailgate door began to open and close, the computer panel on the dash began to blink indicating a complete electrical failure. He was able to make it home. However, the next the day, the battery was dead. Aaa came out and replaced the battery, but the charge did not hold for very long. He was able to charge the battery long enough, to get to the dealer. Once at the dealer, a diagnosis revealed a complete electrical shortage. Two weeks after the repair, while driving down the road, the wipers, lights, blinkers and locks stopped working. The vehicle was taken back to the dealer once again, and a diagnosis revealed another electrical shortage. The repair was done free of charge.

Vehicle will not accelerate after a stop at a light or after taking a highway from a ramp, the engine will rev up but the vehicle will not change gears, after a pull over to the shoulder of the road shutting off the engine and restarting it will run normal. This happened for about 20-30 times until yesterday I get out of work pulled out of the parking lot noticed the vehicle was in limp mode stuck in 2ND and will not change gears. I did some research and found out that the cause was from the valve body of the transmission or the conductor plate and only the dealer IS aloud to repair it ???. And will cost around $2500 .i read that lots of people are having problem with this 722.9 7 speed transmission and mbusa IS not issuing a recall. Nhtsa should look into this and force mbusa to recall all defective vehicles and replace the valve body at no cost because its a safety issue. *tr

- 11008323Complaint Headlamps fogged or droplets forming. Cause Due to its outlet openings, the headlamp is an "open system". This means that acidic gases, moisture, dirt and exhaust gases can penetrate into the headlamp. This can lead to the formation of condensation on the lens of the headlamp. The headlamps comply with all applicable US standards and regulations. Remedy Check housing cover of lamp unit for natural fogging or condensation as per LI82.10-P-078301. If a reduction in the degree of fogging is visible, the desiccant packs can be used once the condensation has completely evaporated. Note: Order service covers and desiccant packs based on the validity description. 1. Remove headlamps. 2. Remove all grommets from outlet openings. 3. Seal vent openings with sealing profile. Important: All openings must be sealed carefully for the pressure compensation diaphragm to work properly! 4. Remove existing service cover. 5. Place desiccant packs into the new service covers and bolt down (Picture_01). 6. Glue the new diaphragm onto the intended surface at the service cover (Picture_02). Note: The bonding surface must be clean and dry. 7. Attach service cover with desiccant pack at headlamp. 8. Install headlamp. To ensure that the desiccant pack (absorption) acts effectively, the headlamp has to be air-sealed. Observe or check the following points for this: 1. Seals at the central connector must all be present and correctly fitted (Picture_03). 2. The new transparent diaphragm must be correctly bonded (Picture_04). 3. Check headlamp housing for any external damage.
- 11008091Complaint During a phone call, the called party has difficulty understanding/cannot understand the driver, or interference/background noises are audible to the called party during a call.

- 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.

- 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).
