I have a 2020 GLA 250 4 matic mileage 62000 with a rear differential failure Was confirmed by a dealer. Mercedes is aware of this problem, there should be a safety recall before someone gets hurt.
NHTSA complaint 11768142A bicyclist claims I almost ran him over. I didn’t hit him, but he fell over and made sued my insurance company. He claims he was at the right side of my car as I was merging towards the right to make a turn. If he was indeed in my blind spot, then it’s important to note that the blind spot assist didn’t alarm and that the design of the passenger seat does create a blind spot, especially for someone of short stature since I cannot see over the passenger seat. To avoid anything like this, I’ve had to remove the passenger headrest, it even at the lowest to the ground setting, the top of the passenger seat is higher than the rear passenger window, but at least the headrest no longer obstructs the view over my shoulder
NHTSA complaint 11757199Had just gotten on the expressway, when a loud gunshot noise was heard. Out of fear, I ducked down, thinking it had actually been one. However, I heard a lot of wind coming in as if a window was down, when I look up, majority of my panoramic sunroof was gone. No messages or warnings appeared on the dash, and I pulled over to document photos and videos. The shade below the sunroof was not damaged, seems to be an internal force that made it explode and shatter into a thousand pieces.
NHTSA complaint 11682723Problem has been confirmed by dealer that the rear differential assembly needs to be replaced. This is a very common defect with gla250’s. It been recalled in the past and Mercedes Benz is putting many drivers at risk. The estimated to replace is $6100! Mercedes Benz corporation refuses to replace the part only offering $1300. That is submission that they are aware something is wrong. I don’t feel safe driving a 2020 car. There have been many class action suits but there needs to be another investigation and recall which MB knows there is a problem and hazard
NHTSA complaint 11664899The contact owns a 2020 Mercedes-Benz GLA250. The contact stated that while driving 35-40 MPH, the check engine warning light illuminated.

The vehicle was taken to the local dealer, where it was diagnosed that the fuel injectors needed to be replaced. The vehicle was not repaired. The contact stated that the failure was related to TSB No: 2022030003. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 86,000.
NHTSA complaint 11620953My Mercedes Benz GLA250 has a faulty rear differential and began shuddering and driving poorly when it had 44K miles on it. This is a very premature failure as diagnosed by two repair shops and is happening to thousands of this model Mercedes Benz. The damage can be catastrophic if continued to be driven as the differential metal continues to deteriorate and possibly have metal shavings travel into the engine. I was told initially by Mercedes Benz it was bad tires! I replaced the tires and the shuddering became worse. I searched for the problem myself on the internet as the problem continued to worsen and countless people are complaining, saying it’s the rear differential. The cost is between $4K and $5K to replace.

NHTSA complaint 11575791Transmission problem. On several occasions while driving, the car has lurched to a stop because gear changed suddenly from Drive to Park. At other times, the engine revvs and slows when it suddenly switches from Drive to "M1." After stopping, it goes back to "D" on its own. Serious safety issue, as I can get rear ended in traffic, or cause an accident for stopping without notice. I have one photo of the sudden transmission switch to M1 (today). Car has been towed to Mercedes service department; no other inspection yet. No warning lamps. Only that it is happening more frequently.
