“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.”Owner report · Unknown Or Other · Aug 2025
“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”Owner report · Fuel/Propulsion System · Jun 2025

“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.”Owner report · Unknown Or Other · Oct 2022
