Mercedes-Benz Australia has issued a recall for the 2018-19 model-year CLS four-door coupe over concerns the 48V on-board electrical system could fail.
"The electric line for the power supply of the coolant pump may make contact with the engine fan, causing damage," the company says in its recall notice.
"This may lead to a malfunction of the coolant pump or a deactivation of the 48V on-board electrical system."
If the condition occurs, the engine could stall due to high coolant temperature or the engine may not restart off after the shut-off by idle stop/start or 'glide mode' functions.
Should the vehicle stall while in use, it poses a hazard and increases the risk of accident and/or injury to occupants and other road users.
Owners are advised to contact their preferred dealer to arrange for repairs, free of charge. The original recall notice can be accessed here.
