The following are consumer-reported complaints filed with NHTSA. These are unverified allegations and are not proof that any defect exists.
Had 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.

Strong “gas odor” upon entering car And continues despite opening all windows to ventilate-also on one time occasion - sudden deceleration And “surging speed” alternately While cruising- it feels that the car Will “stop” and it’s worrisome that I may be “hit “ by the vehicle behind me- also several “dashboard warning lights” different messages just “flashed” which also caused some “Panic” on me- brought the car to the shop- all they did ABS sensor replaced- no other issues noted- I read from MB owners forums about MB Recalls about same issues NHTSA 21V-961 NHTSA 23V- 445
NHTSA #11616169
Transmission 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.

Problem 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 #11620953
My 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.
