Rear brakes backing plates rotted prematurely despite garage kept and well maintained status. While driving, noticed loud scraping and grinding noises from the rear left wheel. Took to mechanic and he found severe rust, with deep corrosion and flaking "rotted". He said I was lucky because this was very close to causing the entire brake assembly to fail, which would lead to serious braking problems or "locked out wheel" and loss of control on a highway which would have put me and others at risk. Had similar rust issues with this car that were fixed in the recent past including rusted brake lines and rusted rear subframe. There is definitely something wrong with the manufacturing as the rear subframe had been recalled and got it fixed that way less than a year ago.
- Service brakes
Car was Off and parked when brake line failed. Further inspection was able to identify that brake pipes was slowly corroded thought entire lower part of the brake system causing critical failure of brakes. Extreme safety issue due to the material of metal/coating and position of brake pipping. If operator was not observant, operator/driver would not have any braking and could cause harm.

The driver’s side door handle broke and I was unable to leave the car unless it was unlocked and rolled the window down to open it from the outside through the window. If there was a loss of power and you pulled on the latch and it broke you would be delayed in exiting. There are multiple videos on after market parts to repair the plastic pin that breaks. Tesla seems to be recalling their vehicles for a similar problem recently, why not Mercedes for a known problem????

The electronic steering wheel lock went out causing the car to not start. Upon checking the Internet to see if anyone else was having this problem I found that it was a problem many Mercedes Benz owners have had and it's an expensive one. It's not just with my particular model and it's not limited to older models of the brand either.

I drove vehicle to Publix with no problems. When i tried to start vehicle, key turns but car does not start. There is no cranking sound. I called a mechanic friend and after extensive diagnosis he determined it was the ESL Module which controls the steering. Fortunately i was not driving the vehicle when the ESL Module failed. There is a recall on Mercedes Benz c300 from 2012-2017 for the ESL Module problems but the 2011 is not included. It should be recalled since it is a safety hazard and it appears others have had similar problems according to comments on Google. I have a handicapped wife i take care of and having issues with the steering can cause accidents and injuries. There were no messages or symptoms of the problem prior to the failure. There needs to be a recall or further inspection done on the 2011 Mercedes Benz c300. Car will be towed to a Mercedes Benz dealership for Diagnostics.

1.What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel system failure is a highly critical safety concern, and my life is at risk. It causes malfunctions with the vehicle, for example, the OBD-based emissions test has flagged a lot of (codes P219A, P0300, P0304, P0410, P0305, P0303, P0171, P0301) 5 of the cylinder misfire codes with the check engine light on, as well affecting other parts in the vehicle function properly, acceleration issues, car stalling as though it’s going to shut off. This is a serious matter and Mercedes-Benz is failing to prioritize customer safety, over cost especially when known faults in the vehicle can lead to potentially life-threatening incidents such as fuel leaks and fire hazards. Yes, the vehicle is available for further inspection upon request immediately each day my life is at risk. 2.How was your safety or the safety of others put at risk? My safety and other's safety are put at risk every time I get out on the road to drive my car it's putting me and other' live in serious danger (especially with the extreme increase in car accidents in the local Nashville, TN area). Despite the vehicle now being 3,000 miles over the 150,000-mile extended warranty threshold. I recently purchased the car on [XXX] and was not made aware of Mercedes Benz having any extended warranty coverage for the faulty fuel system that Mercedes-Benz had placed on this model. I can only assume the previous owner the car was reposed from was also unaware of this as well. I believe Mercedes-Benz should still cover the cost of this repair. The fuel system failure is a critical safety concern, and Mercedes-Benz should prioritize customer safety, especially knowing there were faults of poor quality that they discovered with their vehicles and can lead to potentially life-threatening incidents such as fuel leaks and fire hazards.

I just purchased a 2011 Mercedes C300. I was told that for the past 2-3 years the vehicle would constantly bald out the rear 2 tires and would need replaced every 3 months. As I was driving the vehicle I noticed that the rear tires would make weird noises as if it was hutting something. Upon further investigation the rear sub frame is rotted, which based on research appears to be a very common problem with these vehicles. The rear sub frame is rotted in which caused the lower control arms to completely rot off of the frame posing as a serious safety issue for me when driving with my children and a safety issues for others when I drive on the road. On top of that due to the lower control arms completely rotting off the frame it caused the control arms to hit the gas tank which could catch the car on fire. Mercedes has refused to issue this as a recall in due part to their negligence. Customers cannot afford to pay $5000 for a rotted subframe due to negligence from Mercedes. Please research how many vehicles have had rotted subframes for this vehicle. In Germany they will repair the rotted subframe free of charge. Mercedes needs to be held accountable for risking peoples lives.

While I was driving, my seat back suddenly started reclining backward. I could not make the seat stop or go forward with pushing the power seat button control. It kept reclining back, pushing into the back seat and would not stop until there was no power left. Had my child been in the seat behind me, instead of behind the passenger seat, her legs would have been crushed. I took it to a vehicle repair shop and they were able to manually put the seat back to an upright position. I have not let my child ride in the back seat after that incident yet. I just dropped the car off to the Mercedes service department near me.

- Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant…
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

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

- 11010818Complaint Transmission control unit Y3/8n4 (fully integrated transmission control unit (VGS)) not listed in quick test and/or no communication possible with VGS. Cause Transmission control unit Y3/8n4 Remedy It is important that LI54.15-P-057373 is processed before replacing any component parts (transmission 722.9). After processing and complying with the above documents, perform a reset on the transmission control unit Y3/8n4 (VGS) (ignition reset), check that the transmission connector is seated correctly and inspect the PINs for concerns. If communication with the VGS cannot be established afterwards, the component part 'electrohydraulic controller unit (EHS)' must be replaced, as it is not possible to transfer the valve characteristics under the above-mentioned conditions. Installation of a VGS repair kit is not permitted in this case.
- 11010494Complaint 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). Note: -If no reduction in the degree of fogging is visible, the rear lamp is defective and must be replaced. -It is not physically possible to defog the headlamps completely some residual fogging may remain. Fogging does not impair the functionality or the service life of the rear lamps. -Simultaneous fogging of multiple component parts indicates extreme climatic conditions and also does not impair the functionality or the service life of the rear lamps. Remedy 2: You can recognize a defective rear lamp as follows: 1. Check the rear lamps to ensure that no external damage is present, and that the differential aeration cells and the diaphragm are present and correctly seated. -> If there are signs of external damage on the rear lamp, the component parts must be replaced as per WIS instructions. 2.

- 11008873Complaint Tension-releasing impact of the propeller shaft with the force-free in D "KID" function, after vehicle has stopped. Cause The tension-releasing jolt in the drivetrain originates as a result of the "release" of energy stored when braking through the force-free switch after stopping. It is suspected that the longitudinal bearing is being placed under tension here as a result of the vehicle "dropping off". Remedy 1. Mark the installation position of the joint prior to the removal (picture a+b). This is important for vehicles with a weighted drivetrain ex factory to ensure correct installation after operations have been completed. 2. Clean and degrease propeller shaft toothing. The toothing must be free of grease, e.g. through the use of a brake cleaner. Do not use wire brushes, else the surface could be damaged (picture c). 3. Coat propeller shaft toothing with A 000 989 16 08 Antifriction coating. Coat the entirety, ensuring that the subsurface is no longer visible. When doing so, only coat the outer toothing. Ensure that the coat is not too thick, otherwise the coating could chip (picture d). 4. Observe the drying time of at least 1 hour. 5. Lightly grease the propeller shaft toothing at the outer and inner toothing with A 001 989 44 51 12 Grease (picture e).
- 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.

- 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

- 10207199Complaint The range of the integrated garage door opener (GTO) is too short. Cause 1. Vehicles equipped with infrared windows and/or a heated windshield may suffer from complaints involving low transmission power. 2. When comparing the range between the integrated GTO and the garage door hand transmitter, the garage door hand transmitter is tested outside the vehicle. 3. The garage door hand transmitter is being aimed towards the garage door, but the vehicle is in a different position. 4. The garage door drive is old. Remedy 1. The lower level of transmission power is mainly perceived by customers who did not have any infrared windows (code 595) or all-round infrared windows (code 596) or heated windshield (code 597) in their previous model or who have another model without this special equipment in their fleet. The loss in transmission has technical reasons, i.e. a thin metal film is fitted in the windows. Please consider these codes and advise the customer accordingly! Replacing parts does not remedy the problem. 2. Perform the comparison test between the integrated GDO and the garage door hand transmitter under identical conditions. The garage door hand transmitter must be inside the vehicle and must be held at the height of the inside rearview mirror. 3. The customer instinctively aims the garage door hand transmitter towards the door. However, the transmission direction of the integrated GDO depends on the position of the inside rearview mirror, and thus depends directly on the position of the vehicle relative to the receiving antenna of the garage door drive.
- 10207198Complaint The garage door hand transmitter cannot be initialized with the integrated garage door opener in the inside rearview mirror. Cause 1. The integrated garage door opener (GDO) is not compatible with the opening system installed in the garage. 2. The garage door drive uses a rolling code system. In contrast to the fixed code system, the LED in the mirror in this case flashes green after programming. 3. When the handheld remote control is initialized with the integrated GDO, the distance between the handheld remote control and the GDO is too long or too short. 4. The maximum programming time of the hand transmitter was exceeded. The hand transmitter switches itself off after 10s to 20s. However, the garage door opener needs up to 30s to learn the code. 5. The maximum programming time of the integrated GDO was exceeded. The integrated GDO has aborted programming unsuccessfully. 6. The GDO cannot be programmed after replacement (See #9). 7. The batteries of the hand transmitter are too weak. 8. A part of the signal was not registered correctly. 9. The GDO is not programmed to US standards. 10. Errors with Chamberlin MyQ, Liftmaster MyQ, or Craftsman AssureLink systems causing loss of synchronization. Remedy Note: The numbering of the remedies refers to the numbering of the causes. 1. Installation of a universal receiver. Order via the Homelink Hotline. 2. In the case of garage door drives with rolling code system, synchronization of the garage door drive must also be performed. 3. Keep the correct distance when initializing! This can vary between 5 and 20 cm depending on the system. If the initialization attempt is unsuccessful, repeat the initialization process, changing the distance between the hand transmitter and the mirror.
