STRUCTURE:BODY

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.
