  Mercedes Benz settled with U.S Government the diesel emission scandal. There are about 122k class members. Under the settlement, Mercedes gave 122k class members 4 year/48k miles warranty. Under the warranty, MB replaced the timing chain in May 2022 but on April, 2023 while driving on I-95 in Massachusetts, the engine completely got shut down while driving 55 miles per hour. Luckily, no one got injured. But the car was not controllable. I barely pulled to the side of the hwy and called the towing. Brought it to MB of Westwood. MB Westwood did a diagnostics.Below is the note Mercedes Benz of Westwood: The car is still at the dealership if you want to send an investigator, Engine Rebuild/Replace: after further tear down found that timing chain guide rails broke, which then got chewed up from chain and gears into smaller pieces. these small pieces got suck up into the oil pump pick up tube, blocking oil flow. The lack of oil to main engine components caused them to overheat and contacted each other (metal to metal). which ends up heating to a point in which the components stick to each other and not able to move freely any more.. Basically, The replaced Timing Chain destroyed plastic guide rails, which destroyed my engine. I notified Mercedes Benz of USA and the dealership that they need to recall 122k class members and fix the problem, but they refused to take any actions. By ignoring the problem, it could lead to casualties to thousand of people. I hope you take actions and bring Mercedes Benz USA accountable and they start recalling and fixing the problem before its too late.

  I would like to file an official complaint with Mercedes Service center prior to escalating. Due to neglection the part of your authorized dealership, I am confronted with poor and conniving customer service, strong safety concerns, and financial loss. Also, Euro Motors did not report any issues with the vehicle wire harness during the pre inspection. During the pre inspection the only thing Mechanic pointed out was the rear left air suspension bag losing air (see attached videos of pre and post inspection).I brought in my GL350 for the manufacturing recall on September 20th, with sufficient time to file for the $878.75 cash back rebate for Class Action Settlement. Euro Motors of Germantown, deliberately or carelessly kept my vehicle past the due date of the rebate. When I received the vehicle almost a month later, it stalled in the middle of the highway, risking my life as it gave no prior indication of stalling. When I opened the hood to inspect the vehicle, I noticed the harness wires were tampered with. I have actual evidence of the engine prior and post Euro Motors maintenance, which I will make available if necessary. I have lost my trust with this dealership performing and further work, and I would like Mercedes to take further action to ensure my trust in their brand. I can be available for direct discussion with contact information below. On 20th October 2022, I received my car back from the dealer. I was told their mechanic performed all safety inspection and the car is roadworthy. After I inspected my vehicle I found Euro Motorcars Mercedes-Benz Germantown location left a leaking fuel line and return the car back to me. I would like NHTSA to investigate this safety issue. Respectfully, [XXX] Service Advisor: [XXX] VIN: [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

  While driving between boise going to portland, I experienced sudden lost of power in very dangerous traffic situation. There were a road work area, I had semi-trucks in front and behind me. It happened on I-84W, around 20 miles out of baker city or, my car IS well maintained at the dealership barrier in bellevue. There was no warning that something IS wrong. I had fuel, there were no warning lights or similar indication or comming technical issue. the car lost power, I maneged to move to side that the truck behind me didn't hit me! I called a baker city towing, they tow my vehicle to a shop in the town, the shop had run diagnistics, oil was ok, obd gave them 2 failure codes, the trouble code 126800, standart diagnistics could not recognize the failure, further internet search directed tu turbo charge fault and adviced me to contact mercedes. I called barrier, they didn't help me at all, directed me to mb-road assistance, they organized towing my car to mb dealership in boise. I would like to emphasize that the way how the car failed was not a 21ST century experience. No warning, nothing telling me that the technical status of the car deteriorate..

• 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.

• 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
