Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Plain-English summary

Mercedes-Benz USA, LLC. is recalling certain 2019 CLS 450 Coupe and CLS 450 Coupe 4MATIC vehicles equipped with 6-cylinder gasoline engines. The recall addresses a defect in the electrical line that supplies power to the engine coolant pump, which may contact the engine fan and chafe.

This chafing can cause a malfunction of the coolant pump or a deactivation of the 48V on-board electrical system. A malfunctioning coolant pump can increase coolant temperatures, potentially leading to an engine stall. Deactivation of the electrical system can prevent the vehicle from restarting after using the ECO start/stop function or "Glide" mode. Either scenario can increase the risk of a crash.

Dealers will inspect the coolant pump electrical line for damage and repair or reroute it as necessary, free of charge. The recall began on November 1, 2019. Owners may contact MBUSA customer service at 1-800-367-6372 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
