3rd Generation Mercedes-Benz SLK Class Engine Shut Down

The Mercedes Benz SLK Class R172, produced from 2011-present, was released at the Geneva Motor Show, and this German roadster is characterized as lightweight, short, and fast. This two-door retractable hardtop sports car is Mercedes’ third generation SLK, and options include the Intelligent Light System, PRE-SAFE Brake, and DISTRONIC PLUS, among other state-of-the-art features. Although this German import was well received and remains popular, like any vehicle, the R172 has demonstrated some common issues, such as when the engine shuts down.

Drivers have reported that, at highway speeds, their gas pedal has suddenly stopped working. Typically lights appear on the R172’s dash, and the message center states that the vehicle is inoperable. After restarting the car, some drivers find that their import will operate at the speed of five miles per hour, if at all, and oftentimes there is no warning that this issue will occur. Some owners have noticed that the starter will not work, but that the radiator fan will. Signs and symptoms vary.

There are a variety of possible causes for engine shutdown. The engine could be overheating, or, alternately, there could be issues with the crankshaft position sensor, authorization module, or circuit, among a large number of other potential malfunctions. Regardless of the cause, this sudden shut down is a safety issue, which should and often must be addressed immediately.
