The left-rear seatback latch May not be strong enough to withstand certain loads. If cargo were to strike the left-rear seatback, the latch May fail.

What's wrong: Mercedes-benz USA, LLC. (mbusa) is recalling certain 2020 glc300, glc350e, glc43 amg, and glc63 amg vehicles. The power steering control unit wiring harness May have been damaged during the production process, possibly resulting in a loss of power steering assist or an electrical short-circuit.

Communication, Electrical Vehicle recall #21V058000 · 2021 · 1,292,258 vehicles
What's wrong: Please refer to the part 573 report for specific vehicle model details. The software design of the communication module May fail to communicate the correct vehicle location for the emergency call system (ecall) in the event of a crash.
Why it matters: Failure of the ecall system May result in emergency responders being dispatched to the wrong location, increasing the risk of injury following a crash.
The fix: Mbusa will notify owners, and the communication module software will be updated by a dealer, or through an over-the-air (ota) update, free of charge. The recall began March 12, 2021.
Backup camera, Electrical Vehicle recall #21V354000 · 2021 · 343,191 vehicles
What's wrong: 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."
Why it matters: 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.
Backup camera Vehicle recall #22V232000 · 2022 · 126,443 vehicles
What's wrong: Please refer to mbusa's recall report for specific vehicle model details. The rearview camera May not display the rearview image due to a software error. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "rear visibility."
Why it matters: An inoperable rearview camera display reduces the driver's rear view, increasing the risk of a crash.
The fix: Dealers will update the rearview camera software, free of charge. Owner notification letters were mailed July 15, 2022.
Communication, Electrical Vehicle recall #22V365000 · 2022 · 242,722 vehicles
What's wrong: Please refer to mbusa's recall report for specific vehicle model details. An error in the communication module's sim card software can cause a mobile network connection failure, disabling the emergency call (ecall) system.
Why it matters: A disabled ecall system would prevent a vehicle occupant from contacting the emergency services call center in an emergency, potentially delaying emergency responders and increasing the risk of injury.
The fix: The communication module software will be updated through an over-the-air (ota) update or by a dealer, free of charge. Owner notification letters were mailed July 8, 2022. Owner notification letters will be mailed in phases, on July 8, 2022, May 17, 2024, July 29, 2024, and September 27, 2024.
