This Problem Across All Years
Escalating Safety Concern – Loud Clunking, Thumping, and Cracking from Front Axle at Low Speeds We are long-time loyal customers and currently own four identical Mercedes-Benz models. Unfortunately, one of our vehicles, a 2021 mb glb250 has recently developed severe clunking, thumping, and loud cracking noises originating from the front axle area, noticeable especially at low speeds. The problem appeared suddenly and is rapidly worsening. After researching the issue, we’ve discovered that many owners of the exact same model and model year report identical symptoms. This appears to be a widespread and recurring problem that raises serious safety concerns, particularly as it affects the front axle and is uncommon in other modern vehicles of this class and young age. Given the potential safety implications and the growing number of affected owners, we respectfully request that Mercedes-Benz investigate this issue promptly, acknowledge it as a known concern, and provide an appropriate inspection and repair at no cost to us. We love the brand and have always trusted its engineering and safety standards, which makes this experience especially distressing. We would greatly appreciate your immediate attention and a clear response on next steps.

While driving, the panoramic moonroof on my 2021 Mercedes-Benz GLB 250 (VIN: [XXX] ) suddenly shattered without any visible impact or prior damage. It sounded like an explosion, and glass rained down into the vehicle. This could have caused serious injury to myself or my child. There was no indication that a rock or debris hit the vehicle. No vehicles were in front of me, and I have no history of impact damage. This seems to have happened spontaneously, and after researching the issue, I found it is a common problem across various Mercedes-Benz models.

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 sound and could have caused an accident if the car was in active motion. The recommendation now is that the engine needs to be replaced.

My fuel tank cover would not open. Car was under warranty so MB was able to replace the motor of the fuel cap release. Problem, there is no manual release for the fuel cap so if you are low on fuel and need to fill up, you would be stranded. They need a manual release for the fuel cap for safety.

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?

On September 3, 2022 while traveling east on AL highway 110 the sunroof exploded as i was driving. Notified Montgomery county sheriff Department but they refuse to do a report because it wasn’t an accident. The dealership said something had to hit the sunroof for it to Shadder. Explained to the service advisor that there were no other vehicles in the area when the incident happened, so what could have hit it. Was informed by the service advisor that the car didn’t have a recall for the sunroof on this particular model.
