The 2016 Mercedes-Benz SLK300 has 4 recalls, the most serious involving rear suspension lock nuts that can allow the rear axle to steer independently, sharply raising the risk of losing control.
A separate engine recall affects certain vehicles where camshaft welds can fail, causing engine damage and a potential stall while driving. On the electrical side, vehicles with the nine-speed automatic transmission may have an improperly connected backup power supply for the ignition switch, meaning the vehicle can roll if the driver releases the brake pedal unexpectedly. There is also a software issue with the emergency call system, which can report an incorrect date, time, and location during an emergency, potentially delaying responders.
