Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
8 safety recalls, most serious first
1. Backup camera — software update
What's wrong, in plain English: The rear camera may not show an image when reversing. Please refer to MBUSA's recall report for specific vehicle model details. The MBUX multimedia system software may cause the display to remain black, or reboot after startup. This could result in the rearview camera image not displaying properly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
What could happen: A backup camera that displays a blank image reduces the driver's rear view, increasing the risk of a crash or injury.
The fix: The multimedia system software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. Owner notification letters were mailed beginning June 28, 2021. Owners may contact MBUSA customer service at 1-800-367-6373. MBUSA's number for this recall is 2021050012.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2021 AMG GLB35.
- This recall may be fixed by an over-the-air software update. Check the car's screen or app before booking a dealer visit.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-367-6373.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
