What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
On the morning of April 28, 2026, at approximately 7:30 AM, I discovered that the front panel of the panoramic sunroof on my 2015 Mercedes-Benz GLA45 AMG had spontaneously shattered while the vehicle was parked at my residence in Meridian, Idaho.
Sunroof violently broke, opening from front (normal is back) and sticking up 3-4 inches. Luckily this happened in our garage not moving, while simply pushing Close Sunroof button. If this had happened on the highway, it could have ripped off and killed somebody.
After visit, we started the car, and the engine did not start with a symptom similar to. Previous two cases.
I bought the mercedes gla 250 in september 2018 and my check engine light would come on for a day or two and go back off. The check engine did the same thing as before and took it to auto zone and stated it was a positive crankcase ventilation issue.
30mph and suddenly the entire dash lit up, all red and yellow symbols along with a msg in the display to the effect of collision avoidance system inoperative, stop immediately. This may not have been the exact msg. At the same time the car decelerated to a stop almost immediately.
