The contact owns a 2011 Mercedes-Benz R350. The vehicle had previously had the wheel speed sensors replaced eight times since September 2016. The contact stated that while driving at 55 MPH, the ABS inadvertently engaged, causing the front end of the vehicle to dip while the brake pedal was depressed. Additionally, there were grinding sounds coming from the vehicle as it came to a full stop. The ABS and Traction Control warning lights were illuminated. The vehicle was taken to the dealer where it was diagnosed that the wheel speed sensors needed to be replaced. The vehicle was then taken to an independent mechanic. The vehicle remained with the mechanic, awaiting diagnostic testing. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 80,200. Consumer's complaint is a result of several measures but mainly to the continued wheel speed sensor failures which account to a total of eight (8) newly installed brake sensors (Sept 2016 to Nov 2021). Consumer has experienced several times at highway speeds. The vehicle's repeated wheel speed sensor issues are most likely attributed to an undetermined and undefined malfunction.

"Takata recall" for a year and a half, I have been trying to have my car repaired, but mercedes benz here in reno (and fairfield, california as well) has refused to repair it with the statement that parts are not available. I have called the service department and been told the parts are in stock. I have made appointments, but when I show up for the repair, I am told parts are not available. This month, june 4, 2019, I showed up for an appointment made in connection with the recall notice and was told the parts were not available. On june 14, I had an appointment in fairfield, california; I showed up; and again was told no parts are available. I had another appointment on june 24; but again, I received a call from v. Cruz of mercedes benz and told no parts are available. This process has been going for a year and a half. Of late, I have received e-mail notices (second notice, recall reminder, third notice, recall reminder) of which I have made appointments (as described above) but only to be turned away with the statement, no parts are available. it IS very disheartening to know there IS a dangerous condition in my car that could injure my grandchildren or loved ones and to be subject to the kind of games that mercedes benz seems to be playing. On one hand, they send out notices as if they are doing all they can to take care of the recall problem; but on the other hand, they consistently do nothing. I would like to know my options. How serious IS the recall? Am I placing my grandchildren and loved ones at risk? Please let me know. And thank you in advance for giving this matter your attention.

Takata recall remedy remains unavailable. Letters from mercedes benz claimed that the remedy would be available in june 2018. Well, they first said march 2018, then said that was an error. Thinking IS hard. It IS june 2018, and no remedy. Mercedes continues to produce and earn money on tens of thousands of vehicles each month. They could not be inconvenienced to produce parts for their old buckets of junk that may save customers' lives. This IS mercedes after all. A cold actuarial calculation of delaying this recall so that some of the cars are salvaged versus any lawsuits resulting from injured customers. Mercedes, I hope that your abysmal approach to making and standing behind vehicles IS exposed. We will never buy another of this make. Nhtsa, you continue to be one of the lowest performing government agencies in the history of humanity. Congratulations. How does it feel to capitulate to automakers' every whim at the expense of american lives? I hope that it does not feel good, or at least that you feel something.

Takata recall. 24 months after the initial recall, we still have shrapnel in our dash. Mercedes claims a fix IS coming 'soon' and that nhtsa granted them an extension to complete a final remedy. Notably, mercedes has been able to manufacture hundreds of thousands of new vehicles in those 24 months, but they cannot manufacture replacement airbags? Nhtsa IS weak and ineffectual. Mercedes IS apathetic and criminal. I am certain their actuarials calculated the cost benefit of a delayed recall r pair and presented the board with the least expensive path forward. Criminal. Evil. Unrestrained.

Takata recall twenty-two months and counting!! Manufacturer has not produced replacement parts, and recall cannot be completed due to unavailable remedy. Interesting that mercedes benz has continued to produce and sell millions of vehicles in that time, but they cannot produce new airbags.

Takata recall: this vehicle was involved in a recall campaign for over 12 months and was never repaired due to lack of available parts. The nhtsa vin lookup tool now lists no active recall on the vehicle. Why not? When will parts be available? How could ke this possibly be taking so long? Perhaps it been so long that nhtsa's long-term memory has failed.

Please note: this IS not a specific complaint about my vehicle. It IS calling to light an issue common to most or all vehicles on the road. Because there are now so many options for lighting, e.g. Headlamps, daytime running lights, etc. It IS my impression that many drivers now have no idea if their tail lights are on or off at any given time. I think there IS a serous national issue, especially around dawn and dusk, w/ respect to seeing the back ends of other vehicles. Nhtsa should consider requiring auto manufacturers to include dashboard indicators showing the driver exactly the status of both front and rear lights illumination (or not) at all times.

I pulled into my driveway and under the covered portico and placed my car in "park" with the engine running and the driver's side door open.i got out of the car and went to check something at my front door which was forward and to the left of the parked car before proceeding to open the gate across our driveway.the gate IS at the end of an 11 foot long brick exterior house wall on the left of the driveway.i noticed the car moving and on impulse tried to enter the car to stop it.i got my right leg in the door just before the door hit a concrete planter to the right of the front door and shut on my leg mid-thigh.the door then hit the exterior wall of the house and my leg was clamped in.i flattened my body as close to the car as possible in an attempt to avoid being crushed.the car continued to move scraping the door and my front body along the brick wall.when the car reached the closed gate it pushed it open.once the door was past the house wall, it opened and freed me.the car then continued to drive forward to the back yard and crashed into a retaining wall.in the unlikely event I did not get the car in "park" this car has a safety feature wherein the car IS automatically thrown into "park" should the driver's door open under a certain speed.if the driver's door IS open and you try to put the car in "drive" red warning lights come on the dash board.i have tried to recreate these events and cannot understand why the car was moving on its own. *tr

- 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.
Service bulletins
Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.
- 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.
- 11009122Complaint Washer fluid system leaks Cause Various possible causes: 1. Washer fluid reservoir itself. 2. Seal on washer fluid pump/washer fluid reservoir. 3. Washer fluid pump. 3.1. Distributor housing leaks. 3.2. Pump fitting leaks. 3.3. Washer fluid hose cannot be snapped into place on pump fitting. 3.4. Washer fluid hose will not stay on pump fitting, although connector OK. 4. Washer fluid line. 4.1 Connector will not stay on pump fitting because it is broken. 4.2 Sealing ring in connector missing. 4.3 Sealing ring in connector fitted, but deformed and therefore leaks. 4.4 Damage to washer line by animal. 5. Seal on heating washer fluid reservoir/washer fluid reservoir. Remedy Replace defective component parts only. Do not replace any adjacent component parts that are intact. Note: Repair kits for washer line hoses do exist to allow patches for line damage.
- 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. It becomes increasingly difficult to understand as the speed rises. Cause A. Seating of the microphones in the headliner. Side edges are covered by the textile cover (see picture "1") B. Assembly of microphones (B25/20 or B25/21) in the headliner. C. Dirt inside the microphone housing Remedy 1. Press finger on rear of microphone (on adhesive tape) 2. Remove microphone cap from the front 3. Eliminate protruding material residues of the microphone cutout at the headliner, e.g. with a soldering iron. The microphone must be seated in the headliner as shown in picture "2". 4. Push microphone from behind until it is firmly pressed into the headliner 5. Maintain pressure and press/clip cap into microphone from the front. Note: The cover cap must be clearly heard and felt to engage. 6. This procedure must be carried out on both microphones (B25/20 and B25/21) Note: It is recommended to replace the cover caps. The non-woven cloth in the cover cap protects the microphone from soiling and must not be removed.

- 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.

- 11007790Complaint Headlamps fogged or droplets forming. Cause Due to the housing cover with pressure compensation diaphragm, the headlamps are a "closed system". This means that the headlamps are protected against acid gases, dirt and exhaust gas. However, moisture can still enter from two sources. Through absorption and desorption (the commonest cause) or through permeation. Moisture is either absorbed by the plastic material and, when the light source is switched on, it is released from the plastic by desorption, or the moisture penetrates through the plastic materials of the headlamp from outside (permeation). 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 headlamps 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 existing service cover with diaphragm (Picture_01 (1)). 2. Insert desiccant packs (Picture_01 (2)) into new service covers with diaphragm and seal with protective grille and bolt down (Picture_01 (3)). Note: One desiccant pack is required for each small service cover, and two desiccant packs are required for each large service cover. 3. Stick the supplied diaphragm onto the new service cover and attach at the headlamp. Note: The bonding surface must be clean and dry. 4. If the headlamp housing has an additional 2nd diaphragm, this must be covered over with masking tape. Note: The bonding surface must be clean and dry. 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_02). 2. The new transparent diaphragm must be correctly bonded (Picture_03). 3.

- 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

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).
- 10248173Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (MY) 2009-2012 GL-Class, ML-Class, R-Class, and S-Class (164/166, 251, 221 platforms) vehicles, the coding for the engine control unit does not correspond to the specifications as part of the BlueTEC update diesel field measure (aka Emission Modification). This could result in the VIN number not being read out from the vehicle. This could affect the vehicle smog check. MBUSA will conduct an Emission Service Campaign in which an authorized Mercedes-Benz dealer will update the SCN coding for the engine control unit on the affected vehicles.
