  My 2021 Mercedes-Benz AMG GT 43, VIN [XXX] , has had a recurring safety issue with the transmission wiring harness and connector X279. Mercedes-Benz said this connector can let water in, which can cause a short circuit, overheating, and a fire risk while the car is parked and off. That is why the vehicle was covered by recall 24V445 / MBUSA Campaign 2024100002. This same issue was already addressed once before in January 2023 under MBUSA Campaign 2022080010 / NHTSA 22V-533, when the connector was checked and reworked and a bracket was installed. Even after that, the car later had to go back again on November 29, 2024 for the newer recall repair, when the original two-part harness was replaced with a one-part harness. The part that concerns me most is that this is not just a routine repair issue. It is a fire risk that can happen while the vehicle is parked with the ignition off. I am also concerned that the recall and service records do not clearly show the exact completion date in the manufacturer’s system. I am asking NHTSA to record this complaint and review the defect history and repair history for this vehicle. I can provide the recall notices, service records, purchase contract, vehicle history report, and the notice I already sent to Mercedes-Benz USA.

  Available for inspection upon request issue was reproduced at dealeship. Issue IS easy to identify. Vehicule was inspected by dealership, manufacturer IS aware. Fault light on dashboard show a fault icon the 2021 AMG GT blackseries have an active rear wing. A part of the active rear wing IS active but has a high failure which at some speeds can be dangerous because the active part IS not working and do not provide the downforce that it should because of the actator failures. There are a high numbers of replacement requested throught the mercedes network but they are being replaced by the same part # not an updated one to avoid failures. Some owners do not have a replacement due to none in stocks. The 2021 IS under warranty but AMG mercedes has not , yet, informed owners of the potential hazard. The active part of the rear wing when failed IS simply not responsive (not moving according to speeds or braking actions). Please review the issue before someone gets hurt. Thank you

• 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
• 11007673Complaint Damage or discoloration to paint protection films on vehicle. Cause Chip protection films are a wear item that may need to be replaced over the life of the vehicle. They are typically not covered by vehicle warranty. Remedy To properly install a paint/chip protection film, please follow the below guidelines: #1 - Utilize a solution that is 0.2% soap solution (1,000ml of water + 2ml of liquid soap). #2 - Clean the paint surface and ensure it is dust-free. #2a - When cleaning, you can utilize isopropyl alcohol (Rubbing Alcohol) to assist with cleaning. #2b - We recommend a lint-free rag for secondary dusting. #3 - Wet hands with the soapy water solution to protect the adhesive surface. #4 - Remove the backing paper from the film completely. #5 - Moisten the vehicle surface with the soapy water. You can also lay the protective film with adhesive side out onto the wetted surface to also cover the adhesive layer in the soapy water solution. #6 - Remove film and flip over to gently place adhesive side against the paint surface. #7 - Working from the center out, use a squeegee to press the soapy water solution out from under the film. Use sufficient pressure to firmly press the film into the paint surface, but not an excessive amount to damage or stretch the film. #8 - Allow film and paint to "cure" until all of the moisture has evaporated. At this time the adhesive should be dried and cured enough for sufficient hold to release the vehicle.
