2021 Mercedes-Benz Glc 300 Recalls & Complaints

The 2021 Mercedes-Benz GLC 300 has 9 recalls, the most serious being a fuel pump that can shut down without warning, cutting drive power and raising the risk of a crash.

On the occupant safety side, two recalls affect restraint systems: seatbelt pretensioners may not perform correctly in a crash, and side impact sensor connectors can come loose, potentially delaying airbag and seatbelt deployment during a side collision. Both issues raise the risk of injury. The backup camera system can also fail, with the MBUX multimedia software causing the display to go black or reboot on startup, leaving the driver without a rear view while reversing.

Headlights appear in two recalls: the electrical connection behind the headlight housing may allow moisture in and cause the light to fail entirely, while a separate issue involves headlights aimed too high, creating glare for oncoming drivers. Three recalls cover the automatic emergency call system, where different software or hardware faults can either disable the system entirely, send responders to the wrong location, or prevent the vehicle from reaching the emergency call center after a crash.
