Dealer will inspect and adjust headlight aim as needed at no cost.
The 2020 Mercedes-Benz GLC 350e has 6 recalls, the most serious involving damaged power steering wiring that can cause a sudden loss of steering assist or an electrical short that raises the risk of fire.
The transmission wiring harness on this plug-in hybrid model may rub against the front driveshaft over time, wearing through the insulation and cutting drive power without warning. A separate high-voltage wiring harness issue can fail under certain driving conditions and cause the vehicle to stall. These three drivetrain and electrical concerns all carry the potential for a crash if they occur at speed.
On the visibility side, two recalls address the rearview camera system: a software error can prevent the backup image from displaying at all, and a related software issue can cause the screen to stay black or restart when the car is put in reverse. There is also a headlight aim concern, where the headlights may be pointed too high, creating glare for oncoming drivers rather than properly lighting the road ahead.
