Mercedes-Benz is recalling 3,813 vehicles in two campaigns in the US, and the affected models span the top and bottom of the brand's product range.

The larger recall covers 2,956 examples of the 2014 S63 AMG sedan and 2015-2016 S63 AMG 4Matic sedan and coupe. According to the National Highway Traffic Safety Administration, a software error in the engine control unit can cause the high-performance luxury cars to stall when coasting to a stop. While this can initially appear to be normal operation of the stop/start system, the engine doesn't restart when the driver releases the brake pedal. Getting moving again involves shifting into neutral or park and going through the ignition process.

The repair campaign will begin on December 8, and the models will need an update to the engine control unit software. This will also be the second recent recall for the 2015 S63 AMG 4Matic Coupe because another fix will replace their seatbelts.

In a more complicated issue, Mercedes is recalling 857 examples of the 2015 CLA250, CLA250 4Matic, GLA250, GLA250 4Matic, and the 2016 SLK300 because a weld on the camshafts might be in the wrong place "due to a production deviation at a supplier." Potentially, the important parts could break and damage the engine. Beginning November 30, dealers will replace the affected camshafts as a precautionary measure.
