The steering wheel airbag spontaneously deployed with no prior warning sensors activated or collision (moments after pulling into driveway at home). Mercedes Benz refuses to take any responsibility, or at least inspect and replace the steering wheel and airbag. Driver's arm was partially injured due to deployment, not severe. However the concern remains of whether this could have deployed while driving, causing critical injuries. Should we worry about the remaining airbags spontaneously deploying?

Was driving my vehicle on the freeway and pulled off on and exit ramp. Brake pedal went to floor with very little braking had to pump the brake pedal to regain control. Brakes felt soft. Returned home by pumping brakes. No warning lights, Next day bled brakes and replaced brake fluid. Function restored but no cause could be identified for the air in the brake lines. Very disturbing and unsafe. Sounds very much like 22V315000.

In the past several weeks, whenever I press on the brake pedal firmly at a stoplight or even on the highway, the "low brake light" alarm on the vehicle turns on. I went and checked the brake fluid level, but it is normal. It also seems to take longer to brake the car than before. I'm not sure if it is related to the recent recall or not.

I saw a recall for vehicles with the same year as mine but there IS no recall for the GL 450 that I can find. I called mercedes which yielded nothing.they told me the recalls are vin specific, not vehicle specific. I guess my vin wasn't chosed even though it has the same issue as the ones they recalled in 2009. This IS a new sam. It was replaced by us when we bought the vehicle used.

On several occasions the engine has shut down without warning. this has happened at idle (stopped at a red light) and when traveling 70+mph on the interstate. the event happens very fast and the engine restarts within 30sec. the warning lights on the dashboard light up like a christmas tree but all systems continue working (ac, radio, etc). I have taken it to 2 different mechanics and neither one has been able to identify the problem. this has been very scary and makes me feel unsafe driving this vehicle.

While driving on the freeway at approximately 60 mph, the vehicle randomly shut-off with no warnings whatsoever, including all the internal electronics (e.g. Navigation, dashboard). After 1 second, the vehicle restarted all by itself. The clock inside the vehicle kept on circling back and forth as if some lightning hit it or something, and it was very scary, since there were many cars on the freeway.

The following condition appeared within the last couple of months. (I put a date of 1/1/18, in the box below, but the problem has occurred at least a dozen times since then, and I find it unsafe to drive the vehicle any more). at higher speeds, the vehicle's transmission will downshift to by itself into 1ST gear suddenly and without warning. Even at freeway speeds rpms will suddenly jump up to "red-line" limits as the downshift occurs from 7TH gear to 1ST gear. The vehicle must be brought to a complete stop and engine must be turn off and restarted for transmission to engage properly. It's very dangerous when other vehicles are following or in adjacent lanes traveling at high speeds. also, after driving at higher speeds, vehicle rpms drop suddenly and without warning when coming to a complete stop. Transmission basically disengages and will not re-engage even when gas pedal IS pressed. Engine must be turned off completely and restarted for transmission to engage. Equally dangerous condition - especially when decelerating on freeway off-ramps. the vehicle has been well maintained (all service records are available), and I am the original owner (bought new in late 2006). The vehicle has been driven approximately 117,500 miles as of february 2018. what alarms me the most IS that I have seen many other owners of the same vehicle report exactly the same dangerous transmission problem. Even my independent mechanics says its a well known problem. I say it's a dangerous problem. I should know, in part because I have been registered traffic engineer for over 39 years, and was a past recipient of a national highway traffic safety administration fellowship in highway safety.

- 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).
