The component that appears to have malfunctioned is the front axle integral carrier (front subframe) and the related front suspension geometry, as the vehicle now exhibits a persistent pull to the left and degraded steering stability after the dealer replaced the front lower control arms, engine mounts, and performed alignments; this area of the vehicle is fully available for inspection upon request. My safety and the safety of others were put at risk because the vehicle requires constant steering correction to avoid drifting left, creating a danger of unintended lane departure and loss of control, which aligns with the steering‑related risks described in NHTSA Recall 21V990 / MBUSA 2022070009, where failure of the integral carrier can impair steering and increase crash risk. The problem has been reproduced by me on every drive, though the dealer stated they “did not find anything,” despite alignment printouts showing front camber imbalance and lack of caster correction. The vehicle has been inspected twice by the authorized Mercedes‑Benz dealer, but they did not inspect or address the front axle integral carrier even though the recall documentation shows that corrosion or structural issues in this part can affect steering performance and connection to other components. There were no warning lamps or dashboard alerts; the symptoms began immediately after the dealer’s suspension and mount repairs, and the steering pull and unstable handling have continued ever since.

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.

Front right ball joint separated from lower control arm with no advance warning and the drive shaft was disconnected from the vehicle body. I was travelling at about 15 mph in a straight line through an intersection on a flat surface with no potholes. Then I saw a warning of a transmission fault in my instrument cluster, followed by a loud grinding sound. My car then came to a stop and I was unable to move the vehicle in Forward or Reverse gear. I ignition cycled the vehicle and tried forward/reverse, then someone told me that my front right wheel had separated. Upon inspecting my car from the outside, I then saw the mechanical failure that had occurred. The ball joint separated from the lower control arm . The drive shaft from the front right wheel also separated from the vehicle body. I also noticed that a ring-connector for the drive shaft had been flung maybe 4 feet from my car. My car was in a non-driveable condition and I could not engage drive with the transmission, my car had to be towed from the scene. If this had happened on a busier street or at higher speeds this would have been a severe collision. My car was just delivered to a Mercedes Dealership after sitting in a tow yard for several days, they have not yet fully inspected the vehicle. My insurance has not yet sent a representative to see the vehicle. The indication I had was a "TRANSMISSION FAULT" displayed on my instrument cluster, but I did not notice any other telltales on the instrument cluster after coming to a stop. To the best of my knowledge I did not collide with any objects before the event. There is damage to the outside of my front right rim and tire in the photos, I believe this damage occurred as part of the mechanical failure and how the tire may have deformed and the rim contacted the ground.

This vehicle was purchased new, in cash, from the Mercedes-Benz dealership in Bellevue, WA. It was delivered to me, without being warned about the car being equipped with summer tires, the state of Washington has continuous rain, snow, and ice in a regular basis throughout the years, summer tires are not a good tire for an SUV such as this GLB unit in this region. On 12/27/2021 I went on an errand around my neighborhood, the road had snow and ice, and it had been serviced by our city's plows and deicer was present, during three occasions I had to stop for traffic lights, and my car skidded during all three occasions almost hitting another vehicle, and a pedestrian, my car was the only car skidding on the road, I am an excellent driver with not a single accident on my responsibility, and I have driven on snow and ice for years; this was not a novice's error. Furthermore, the car has a loud "clunk" noise coming from undercarriage, and sensations of tire slipping, possibly front and right corner, specifically when I perform a slow speed U-turn. This vehicle has not been damaged and has about 3,000.0 miles in the odometer, on 12/14/2021 I took it to the Mercedes-Benz dealership for inspection, they did not find any reason for the "clunk" noise and slipping of tires; this is when I was informed that my tires were summer tires and I needed to buy new all-weather, or winter tires, the tires "would not perform" in the winter, I was told by the M-B service representative. Here I am with a "high quality" new vehicle, with clunky scary noises, while sensing of tires slipping, and the dealership claims it to be "normal" and "safe", on top of that the car was equipped by factory with substandard tires for the region of final destination, all of which may cause accidents, damages, and/or injuries.
