UNKNOWN OR OTHER
My car had 78,530 miles on it when the rear differential binding causes shuddering/thumping during turns, which risks sudden wheel lockup or loss of control on sharp turns or low-traction surfaces. Please Note that Mercedes-Benz acknowledged this issue in TSB LI35.31-P-072105 but has not issued a safety recall. Dealer Diagnostic & Repair: Dealership confirmed a total component failure of the rear differential. The entire rear axle differential assembly (Part #A1763503100) and related hardware had to be removed and replaced. Total cost for rear axle replacement alone was $7,541.30.

I was driving my vehicle and it shifted into neutral and would not go back into gear until I pulled over to side of the road, turned it off and back on. A check engine light came on when I restarted the vehicle and I took the vehicle to the dealership for diagnosis. They told me they couldn't find an issue and reset the check engine light. A week later, I was driving on the freeway and it shifted into neutral again at 70 miles an hour. Luckily, I was in the right hand lane and was able to coast to the side. At that point I started looking online to see if others had this issue and came across this: Campaign No. : 2021020038 NHTSA ID: 21V033 Campaign Desc. : Replace Transmission Control Unit 21P5495403 Which is exactly what is happening to my vehicle

My turn signals are not working and warnings are showing up on my dashboard. My pillars are both wet on the drivers side and passenger side. My speed odometer and tachodometer are not working. The dash board iis showing the brake and high beams are on but they aren't on. I have fog on the front window when I get in the car. This situation is of major concern for my safety. I am not certain that the air bags would work? I refuse to drive this vehicle. I called Mercedes Benz in Wilmington, NC and I can't get an appointment until October 13th. I see in the Mercedes Benz recall that the sun roof and electrical problem were recalled.in 2019. I have a Mercedes Benz GLA 250 2019 and that was in the article. Mercedes told me my vin number was not included in the recall. I have the exact same problems as the other vehicles that were recalled. I appreciate your help in this matter to be put on the recall list. This is a major recall issue. I am in fear for my safety to drive with all the electric issues that exist as a part of this recall. Please notify me once this is approved so that I can call my dealership and have this issue resolved. I appreciate your immediate attention to this matter as this is my only transportation. Thank you for your attention in this matter [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
The ABS Sensor light, engine light, anti skid light and 4 matic malfunction, transmission malfunction all lit up on my dashboard on Tuesday July 22, 2025. The stearing would lock up and the brakes would not break it also shifted gears into neutral. The dashboard finally told me in bold red letters (transmission malfunction STOP). It would do this then all the lights would go away. I thought it may have just been the battery since I hardly drive the car. The shop cleared out all the malfunctions and re drove it and they said it appeared fine but the next day (Wednesday) it acted up again and that is when I got the transmission malfunction STOP warning on the dashboard. I pulled over and called the shop to come tow my car. By Thursday they said they couldn't diagnose or fix the problem but stated it had to do with the Transmission and to have it towed to the Mercedes Benz dealership. I had it towed to the Morristown, NJ Mercedes Benz service dept and they stated that it appears that it is the Transmission Valve Body. I spoke with Mercedes this morning (July 28, 2025) and that is when I learned it was the Transmission Valve Body and that it is going to cost me $4,000.00 plus labor. This makes no sense as the car has less than 26,000 miles on it. I researched a bit on this and found that there may have been a recall for this car but I was never notified of the recall. When the service rep told me that he was waiting to hear from corporate on this before he could give me an exact cost (this was after the technician stated what the issue was). I got suspicious as why would they need to contact corporate to figure out the cost of the repair. I could have gotten into a really bad accident if I was on a major road going 65mph.

In December 2023, the check engine light came on. The dealership said it was the rear differential. The dealership fixed the problem under warranty. In July 2024, the problem returned. The dealership said it could repeat the procedure from December, but that eventually the rear differential will need to be replaced. The dealership said that only replacing the rear differential will fix the problem for good. Obviously, MB recognized the problem and upgraded the software and whatever else was wrong with the current rear differential. The car is now out of warranty. Clearly, MB knew of the problem and chose to direct it's dealerships to use stop-gap measures that do not fix the problem, until the rear differential must be replaced, at the owner's expense, with an upgraded rear differential. It is dangerous to drive the vehicle with a faulty rear differential.
