  The left rear subframe separated from the main frame causing the car to pull to the left when braking. I had an episode where I was stopping for a traffic light and the car started fishtailing and I almost lost control of the car. Following this episode, I took the car to a mechanic who advised me that the car was unsafe to drive. My mechanic also told me that he has repaired a number of these vehicle with the same problem, and that Mercedes Benz has extended their warranty from 4 years 50,000 miles to 20 years unlimited mileage. They did the extension after someone filed a class action suit in Georgia about the problem. The vehicle is presently at a Mercedes dealer awaiting the new subframe.

  To Whom It May Concern, I am seeking assistance regarding my 2014 Mercedes-Benz C-300, VIN [XXX] . I repurchased this vehicle from the London Nissan Dealership on [XXX]. It currently has about 120,000 miles, and I have driven an additional 15,000 miles in the past two years. Less than three months after purchase, I took the car to a Mercedes-Benz dealership in Knoxville, TN, for repairs on May 16th. Now, my vehicle is at James Motor Company in Lexington, KY, where they diagnosed a faulty steering column that needs replacement at a cost of $1,630.00. I have already taken this car to the dealership twice for issues in under two years. The problems began when the vehicle wouldn’t start one morning; the steering column was locked despite a fully charged battery. This failure could have led to a serious accident, especially since I drive frequently for work and school. There were no warning signs prior to this incident. The dealership has confirmed the steering column issue and can provide inspection upon request. I also have a list of parts needed for the repair available. Given the nature of this malfunction, I believe it warrants a recall. Thank you for your attention to this serious matter. I look forward to your prompt response.

  I purchased my vehicle from the Mercedes Benz Dealership and received a recall letter in the mail stating that driver side deployment may occur. After receiving notice I brought the car to the dealership to get the recall repaired. I've been driving around with a false sense of security believing that this issue was repaired. However, recently, while I was driving the driver side airbag unexpectedly and abruptly deployed and injured me. This is a major safety concern and car owners should be notified and made aware that the issue can still occur after the recall was repaired. I contacted Mercedes Benz and they did not issue any additional notices to inform customers of possible recall issue reoccurring due to manufacturer defects even after the repair was made. Additionally, I believe the driver side Takata airbag/inflators may have also been defective because of the injuries I incurred from the forceful explosive eruption of the airbag. MBUSA Campaign Number 2017120024 NHTSA Recall Number 17V627 Recall Start Date January 18, 2018 Recall Reported Date October 16, 2017 Component(s) 1709P46C62 Daimler AG (DAG), the manufacturer of Mercedes-Benz vehicles, has determined that certain MY12-17 C-Class, E-Class, E-Class Coupe vehicles (204, 207, 212 platform) have insufficient electrical grounding in the steering column components. In rare instances, if the steering column module is exposed to an electrostatic discharge, and if the steering column module clock spring is broken (due to wear), this could lead to an inadvertent deployment of the driver airbag. An inadvertent driver airbag deployment may cause a risk of injury to the driver and might increase the risk of a potential crash. A broken clock spring will illuminate the SRS warning light as well as display a warning message in the instrument cluster. An authorized Mercedes-Benz Dealer will install a sufficient ground to the steering column, and a protective ring to the steering column module.

  While I was driving my car the driver side airbag abruptly deployed. The airbag inadvertently deployed; the car did not crash into anything to cause the airbag to deploy. When the airbag erupted it caused injury to my head, face, hand, arm and wrist. I believe the airbag is defective because I have lacerations on my face possibly due to sharp objects ejecting from the airbag and the impact as well as excessive smoke and fumes emitted after the fact. I believe there might be a manufacturing defect in the airbag because it seemed as if it exploded with excessive force causing harm to myself as well as inadvertent eruption. There have been some recalls issued on the motor vehicle and I did take the vehicle to the Mercedes car dealership to get all of the recalls repaired, however this incident occurred after the repairs were made at the dealership.

  The driver's side interior door handle became disengaged as I was trying to open the door so I was momentarily trapped inside. If I had been in a situation where I had been in an accident and needed to get out quickly, or the car had been on fire, or I was stalled on the train tracks, this could have been a serious incident. When I googled this, it sounds like this is a very common occurrence in Mercedes. There was no warning that this was going to occur - everything seemed secure before this happened. I have taken it to a service center for a very expensive repair as they have to remove the door panel, replace/reattach the part and put the door panel back.

  Car has approximately 60,000. miles. Upon it's state inspection Mercedes Benz service center indicated rear subframe is rusted. Service advisory says it is okay now, but will need to be replaced. Searching Mercedes forums, I've noted this is a n oft reported issue. Many do not realize there is an issue until it breaks and car pulls to one side at rear upon braking. Others have experienced rusted brake lines at the same area as the subframe issue. Others have noted damage to the gas tank from suspension parts banging the fuel tank after it breaks. I realize this is a 8 year old vehicle. But the vehicle shows zero signs of rust on the undercarriage except for the subframe. Sure seems like a manufacturer's defect that should be recalled by Mercedes. Because of safety concerns, I now have to decide to repair or trade the car because of safety concerns. But the rusted subframe zaps the value I thought I had in the vehicle for a trade. What is the protocol for manufacturer's to issue safety recalls. Sure seems like this one qualifies.

  I purchased my car one year ago from a Mercedes dealership - 8/31/2021. I brought it in for service at the same dealership a week ago and they told me the rear subframe rusted from the inside out and it FAILED inspection. The parts are $5,100 and not available until some time in Q1 2023. There is no way a car rusts from the INSIDE OUT in one year. I have another vehicle in the same driveway, same everything and there is no rust anywhere. We have had all of our cars at least 10 years. This was a "new" car for us. MBUSA said they could do nothing because I own the car and didn't get financing from them. My dealership so far is not helpful. My service guy (he has been for 10 years) says this is common?? My client (a different car manufacturer) says it is not and it is terrible. I don't know why it rusted but this is a defect in the car because we didn't flood it. It's dangerous.

• Desiccated Air Bag Inflator Rupture

  EA21002Opened Sep 17, 2021Open
  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.

• 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. Check the electrical connectors of the plugs and pins. -> If moisture/corrosion/etc. is present, the component part must be replaced as per WIS instructions. 3. Check for leak tightness -> Close all openings with Terostat IX or similar and establish and stabilize via an overpressure (4050 mbar) via the plug. -> In the event of a sudden pressure drop, the component part must be replaced as per WIS instructions. Note: External damage to the rear lamps does not constitute a warranty or goodwill case.

• 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.

• 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.
