FOUR WEEKS AGO I TURNED ON MY CAR AND SAW A WARNING LIGHT THAT SAID "LEFTSIDE CURTAIN AIRBAG MALFUNCTION". I IMMEDIATELY CALLED THE MERCEDES 800 NUMBER AND THEY TRANSFERRED ME TO MY LOCAL SERVICE CENTER. I TOOK IT IN AND THE GUY WAS SUPER NICE, THEY PROVIDED ME WITH A LOANER AND HE SAID HE WOULD CALL ME WHEN THE WORK WAS COMPLETE. HE CALLED ME THAT EVENING AND TOLD ME THAT MY CAR WAS READY. I PICKED IT UP THE NEXT MORNING AND THE WARNING LIGHT WAS GONE. YES! FLASHFORWARD THREE WEEKS AND THE WARNING LIGHT CAME ON AGAIN. I CALLED THE SERVICE…

In April 2025, my 2021 Mercedes-Benz GLB 250 (81,000 miles) suffered repeated engine issues caused by a cylinder head failure. The dealer attempted a cylinder head replacement, but during their own test drive after repairs, the engine completely seized and failed again on their property. This indicates a severe defect in the engine assembly that risks sudden power loss while driving, which could cause an accident. Prior to the failure, there were warning messages about misfires and rough idle. The problem has been confirmed by an authorized Me…

The car has 29,000 miles and I took it on a two day trip across part of the country. It was driven hard but had a oil change before leaving. After arriving home it started to sputter and have no "energy". I had the cabin filter and engine filter changed and another oil change just in case. took it to deal as it continued to sputter, even worse, jerk forward. It blew a cylinder head. Checking the internet I find that this is a usual problem with this year and model car. Why isn't it in the recall if a lot of this model has this problem?

Jerking and loud noise from the engine after attempting to accelerate from a red light stop. Vehicle is idling very roughly and almost sounds like a diesel engine. Check engine light came on. Inspection at the dealership found multiple faults for camshaft positions deviating from the specified value. When the oil filter was removed, the shop reported finding some metal particles in the oil. The conclusion was that a mechanical fault caused a metal part in the engine to brake and clog up the engine. The car did not run smoothly after the jerking…

Family and I were driving on the interstate and heard a loud bang (like a shotgun) followed by immediate glass everywhere. The panoramic sunroof exploded. We had to drive 4 hours like this - lucky we didn’t jerk the wheel on the interstate with the noise. Absolutely sickening that this is so prevalent and Mercedes won’t do anything about it.

1. Transmission Problem Vehicle Rolls backwards when the gear / transmission is in "Drive". It happens in these two situations: a) I am stopped at a Traffic Light which is Red. The road is at a moderate upward incline. When the Light turns Green, and I move my foot from the Break pedal to the Accelerator to move forward, the GLB rolls backwards even though the transmission is, and has been, in "Drive". b) I am backing out of my garage. Our driveway is at a moderate Backward / Downward Decline. As I reach the point where I shift the gea…

this car really has a lot of issues and honestly if I didn’t know what to do last night and didn’t know about cars, it could have seriously cost me my life but luckily I was able to move out the way of a truck that was coming fast behind me while I was at a traffic light and when the light turned green the car would not start back up from the automatic stop when you make stops and because the auto shut off never came back on and I had to literally make a split second decision and put it in park and start up again and go quick.
