What owners report
SUBJECT: URGENT: Safety Recall Campaign 26V481 / XXXâ Unreasonable Remedy Delay and Economic Hardship (VIN: [XXX]). I am formally logging a safety complaint regarding the unreasonable delay by Mercedes-Benz in providing a remedy for NHTSA Recall 26V481 (Mercedes Campaign XXX), affecting my vehicle (VIN: [XXX]). The manufacturer reported this critical defect to the NHTSA on XXX. Despite months having passed, and with owner notifications scheduled for XXX, the remedy remains unavailable. My local authorized dealerships (Mercedes-Benz of West Palm Beach and Delray) have canceled my service appointments, stating they have zero parts allocation from corporate and cannot perform repairs.

The contact owns a 2020 Mercedes-Benz GLB250. The contact received notification of NHTSA Campaign: 26V481000 (Latches/Lock/Linkages); however, the part for the recall repair was not available. The contact stated that while attempting to Park the vehicle, the parking brake independently engaged. The ABS warning light was illuminated. The vehicle was taken to a local dealer and the failure was confirmed. The failure mileage was approximately 70,000.
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.

The recall specifically states: âMercedes-Benz AG has determined that on certain Model Year 2019â2021 A-Class and GLB-Class vehicles, the corrosion protection of the integral carrier of the fro

Oringally took one week prior and diagnostics led to the possiblility that the cylinder head was malfunctioning, which was a manufacturing defect and covered under an extended warranty, but now advised otherwise. Quote $2200.00. Mileage on vehicle 23,660.
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 Walma
