I am submitting this complaint because I believe the repair performed under NHTSA Recall 21V990 / Mercedes-Benz Campaign 2022070009 in May 2024 failed to adequately correct the safety defect identified in the recall.When driving my axle snapped causing my tire to pop out and me to loose control of the car causing a crash into the curb. I have since been without a vehicle with Mercedes Benz of Augusta denying my vehicle after having it towed. They refused to even look at it seeing the axle issue. The recall specifically states: “Mercedes-Benz AG has determined that on certain Model Year 2019–2021 A-Class and GLB-Class vehicles, the corrosion protection of the integral carrier of the front axle might not be sustained over the lifetime of the vehicle. Under specific environmental influences, corrosion of the integral carrier of the front axle might occur after several years. As a result, depending on the intensity and location of the corrosion, an impairment of the structural durability of the integral carrier as well as the connection to other components cannot be ruled out. In this case, vehicle steering might be affected which could potentially increase the risk of a crash.” My 2020 Mercedes-Benz GLB 250 received the recall repair in May 2024. Despite the recall repair being completed, the vehicle subsequently experienced a serious front-end/steering-related mechanical failure involving components connected to the front axle, resulting in an accident and loss of steering control.I am particularly concerned because the failure occurred in the same general front-axle area addressed by Recall 21V990, and the recall itself specifically identifies the possibility that deterioration of the integral carrier and its connections can affect steering and increase the risk of a crash.I am requesting that NHTSA investigate whether the May 2024 recall remedy was properly performed and whether the recall remedy adequately addresses the underlying safety defect in this vehicle.

I am submitting this formal complaint regarding a serious safety incident involving my 2020 Mercedes-Benz GLB, which directly reflects the defect outlined in Recall 20V-480 (Rear Spoiler Detachment). Although my VIN is not officially included in the affected range, the exact failure described in the recall occurred on my vehicle. On or about June 16, 2025, at approximately 3:00 p.m., I was driving and I noticed an object in my rearview mirror that had become airborne and was causing vehicles behind me to swerve to avoid it. Moments later, two separate vehicles pulled up alongside me, and the drivers began waving their arms to get my attention. I exited the roadway and pulled into the Walmart parking lot, where a couple in a pickup truck approached me and informed me that the rear spoiler of my vehicle had flown off. I got out to inspect the vehicle, and indeed, the spoiler was completely gone. I returned to the area where I first saw the airborne object, attempting to locate the detached part, but was unsuccessful in recovering it. I contacted Mercedes-Benz USA and my local dealership on June 17, 2025, and was told that because my vehicle’s VIN is not listed under the recall, I would be responsible for the full cost of inspection and repair. Frankly, that position is unacceptable for the following reasons: - Recall 20V-480 describes a defect involving improperly welded rear spoilers on 2020 GLB250 models, which can detach while driving. That is exactly what happened to my vehicle under normal conditions. - The spoiler detached while the vehicle was in motion, creating a dangerous road hazard—just as outlined in the recall. - The vehicle has never been involved in a collision or sustained rear-end damage. It has not been subjected to outside interference. - My VIN has been included in at least five previous recalls, underscoring that my vehicle was part of broader quality issues during that production period.
