The failed component of the car was the drivers side fuel transfer pump. After noticing the faint smell of gas in my car i checked under the rear driver side passenger seat. I was shocked to find more than 16 fluid ounces of gas floating freely around the well of the gas pump.the insulation under the rear passenger seat is soaked in gas. I can only imagine what could’ve happened if there was an accident or if someone even sparked a cigarette in my car. Not only is this extremely dangerous, there are negative consequences that result from inhaling gas constantly while driving. Gas contains cancerous properties, people should not be subject to unknowingly driving around a car that is manufactured to the defect of releasing cancerous vapors. Who knows what damage inhaling gas fumes for the past months has done to me or my passengers. In the even that someone were to spark a cigarette in the car it was possible that the car could’ve caught fire. The passengers in the rear right seats would be affected the most, the insulation under their seat is soaked in gas. This problem has possibly been noticed by dealers and identified in a warranty that expired on 4/24/2023. This warranty was issued for fuel tanks and fuel components. I am not sure whether the gas pump was affected but the gas pump alone constitutes a recall. This is a very common problem as well, apparently there are multiple youtube videos demonstrating gas leaks in the back seat. Upon contacting dealer I was informed that they did not know if the gas pump was included in a warranty that expired in 4/24/2023. I would have to pay for an inspection to determine if the gas pump is related to the warranty. In the case that it was related the financial obligation to repair is my burden. The dealer wont inspect the vehicle unless I pay, I have documented photo and video of the gas well and the extent of the leakage. There was no warning or any indication that I was driving around with this dangerous issue.

I bought a 2008 mercedes cls and have had it for a while now and with no warning it has started making a banging noise while idling. It idles very rough and shakes my car. I'm unable to drive it safely at this point. The engine is also mimicking symptoms of an idler gear/ balance shaft wearing down due to poor building materials from factory allowing movement of the timing chain. Apparently causing the engine to blow. I don't know what to do now. I don't know if it is covered by mercedes. But I know I am not alone on needing this to become a recall...
- Electrical system
I see there was a recall on instrument clusters on my vehicle in 2001. My instrument cluster is completely black and I can’t see speed or any thing at night. You cant replace the bulb or cluster unless mercedes reprogram it which the price is rediculous. I did some research and seen that Mercedes did some recalls for my vehicle but it doesn’t show up. I was told to contact you guys in regards to this.

Have gotten airbag code b9223. Drivers side iginition squib resisted center IS high R12/9 message. Took it to.local.mb dealer and they want $1800 to fix a airbag problem, which IS something that should be defect free regardless of warranty. this IS an ongoing issues with mb and it honestly seems that this IS done deliberately to generate revenue by selling service for almost $2000 to replace a $50 connector they know IS manufactured in a subpar fashion, expecting it to fail. mb has failed myself and countless others with this one simple problem. There needs to be a recall and they should be forced to fix this problem for their customers. Peoples lives are at steak.

I was driving g through a parking lot when the serpentine belt broke. Naturally, the car became difficult to steer but manageable. As I attempted to turn into a parking spot I heard a 'pop' under the hood. When this occurred, the wheel went into a free spin. There was no input from the steering wheels to the rack and pinion. Upon investigation I found the lower steering shaft broken about 2 inches above the rack spline. The steering shaft was broken in two. The increased force required to turn the wheel was too much for the shaft to handle. *tr

I pulled into a service station to fill my tank. After adding fuel to capacity I began to smell fuel in the passenger compartment. I attributed the smell to possibly spilling fuel on myself. I drove the vehicle to work and then home. The next morning I continued to smell fuel in the passenger compartment. I took the vehicle to the dealer for diagnosis and was told that there was a leak in the tank that was splashing / venting into the passenger compartment. The service technician shared that this was a common problem with the CLS. *tr

On march 10, 2012 my wife started the aforementioned vehicle and immediately began to smell gasoline fumes in the passenger compartment. As she exited the parking garage, the toxic fuel smell became unbearable and she immediately turned- around, re-entered the garage, quickly shut off the car and exited the vehicle for fear of fainting and / or an explosion. the mb rep explained to us that there was a failure in the fuel delivery system; which IS accessible under the backseat of the passenger compartment; and the leakage caused fuel to be pumped into the passenger cabin and accumulate under the rear seat; thereby saturating the insulation, carpet and rear seat cushions. the mechanics replaced the fuel system; and reiterated that the gasoline leaked up into the passenger compartment (from the faulty fuel delivery system located under the back seat of the vehicle), saturated the carpet, the floor insulation as well as the actual seat cushions. in our opinion, a critical vehicle design safety feature (in the event of a collision) IS not to permit fuel to be pumped into the passenger compartment; which would increase the likelihood of an interior explosion, and at a minimum impair the ability of the occupants to safely exit the vehicle, before succumbing to toxic fumes. The dealer service rep?s response was: ?mb has determined that the safest place to locate the fuel delivery system IS under the back seat of the vehicle?. I implied that his response was not acceptable. interestingly, the mb dealer service rep called us and said mb inc. Would cover the cost of the repair. However, repairing the passenger compartment damage and defective fuel system does not alleviate the cause of this dangerous situation. *tr

The Office of Defects Investigation (ODI) opened an investigation based on consumer allegations of loss of rear lighting in model year (MY) 2008-2011 Mercedes Benz C-Class vehicles.Complainants alleged that one or both rear lighting assemblies fail to illuminate (i.e., all lights housed within the assembly extinguish, including the stop, tail, and turn signal functions) or illuminate dimly.In some reports, complainants also alleged that the failure was accompanied by a burning smell emanating from the trunk of the vehicle.When examined, these vehicles showed evidence of overheating at the lighting assembly harness connector, including damaged (blackened) wiring and plastic.The rear lighting failures typically involved one side of the vehicle however in some cases both assemblies failed (although probably not simultaneously).ODI identified 5 fire and one injury allegations during the course of this investigation.Two fires occurred while the vehicles were parked.One originated in the vicinity of the driver?s side light assembly where the fire and associated damage was confined to the trunk area, and the fire self extinguished due to oxygen starvation.As a result of the fire, the vehicle was repurchased by Mercedes and salvaged.The second fire originated on the passenger's side and required fire department response to extinguish; the fire damaged the tail light and surrounding body panels as well as the trunk area and wiring.The vehicle was repaired and returned to service.Two firesoccurred while the vehicle was being driven.In the first instance, the driver detected an odor and pulled over to observe smoking and a small flame at the lighting assembly wiring in the trunk.The owner was able to extinguish the fire before any significant damage occurred.In the second instance, the driver smelled smoke, pulled over, and opened the trunk to find smoke and sparks emanating from the forward facing side of the tail light.The driver was able to extinguish the sparks and drive the vehicle to the dealer. A fifth fire was reported by a fleet manager who observed a vehicle with fire damage originating near one of the tail light assemblies.The injury incident occurred when a technician burned their hand while diagnosing a failed light.The technician touched the tail light wiring which was hot enough to burn him although the injury did not require medical attention.On April 10th, 2014, Mercedes notified ODI that it would conduct a safety recall to remedy the rear light assemblies in approximately 252,867 MY 2008 - 2011 C-Class vehicles including the C300, C350 and C63 AMG models.Each rear light assembly has separate bulbs that act as brake, tail lamp, backup and turn signal indicators.The bulbs are mounted in a bulb carrier which uses a common electrical ground circuit at the harness connection.According to Mercedes, oxidation due to the use of dissimilar metals on the harness and bulb carrier electrical connectors can result in increased resistance and a subsequent dimming or loss of lighting function.The heat caused by the increased resistance/oxidation can also lead to the melting of the surrounding plastic, or in some cases, present a fire hazard.In conducting recall 14V-171, Mercedes dealers will inspect the left and right bulb carriers and harness connectors for the presence of dissimilar electrical connectors and/or evidence of related thermal damage; affected bulb carriers and/or harness connectors will be replaced free of charge.Mercedes notes that service replacement bulb carriers produced from January 2012 eliminate the dissimilar metal condition and that these bulb carriers will not requ

- 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).
