The 2023 Mercedes-Benz CLS 450 has 3 recalls, the most serious being a loose 48-volt ground cable in the engine compartment that can overheat and start a fire.
The fuel system also has a concern: the fuel pump can shut down without warning, cutting drive power and leaving the driver without the ability to accelerate or maintain speed in traffic. On the driver assistance side, a software error can prevent the exit warning system from sounding or displaying alerts when a door is being opened into the path of an approaching vehicle, raising the risk of a collision with passing traffic.
