The 2021 Mercedes-Benz GLC Class has 3 recalls, the most serious involving a fuel delivery module that can fail while driving, cutting engine power without warning and raising the risk of a crash.
The fuel delivery module defect can also cause the engine to run rough or refuse to start altogether. On the safety equipment side, the under-hood fire suppression system has improperly connected lines on certain vehicles, meaning the system may not work as intended after a collision and the engine compartment becomes more vulnerable to fire in the aftermath of a crash. There is also a lighting concern: moisture can get into the headlamp housing through connectors that are not fully sealed, eventually causing one or both headlamps to fail and reducing visibility at night or in low-light conditions.
