2019 MERCEDES-BENZ CLS 450 Recalls — Canada & USA

The 2019 Mercedes-Benz CLS 450 has 6 recalls, the most serious involving a software defect that can cause the engine to stall unexpectedly while driving, raising the risk of a crash. A wiring issue also affects the CLS 450 Coupe: a power line to the engine coolant pump can rub against the engine fan, wear through, and cause the pump to fail or the 48-volt electrical system to shut down, which can also lead to an engine stall from overheating. On the safety systems side, the passenger seat occupant classification sensor may not be properly calibrated, meaning the front passenger airbag might not deactivate when a child seat is installed in that position, putting a child at risk of airbag injury in a crash. The automatic emergency braking radar can also lose accuracy and fail to apply braking as expected when a collision is imminent. The headlights on some vehicles have an unsealed adjustment screw that allows the beam angle to shift over time, reducing forward visibility at night. Finally, on vehicles where the instrument cluster has been replaced, the seatbelt reminder chime and warning light may not function, leaving front occupants without a prompt to buckle up.
