Most modern vehicles are equipped with engine stop/start, which saves fuel consumption in crowded cities and cuts CO2 emissions, but the technology only does half of the job on certain 2016 Mercedes-Benz GLE450 AMG models.
Due to an error within the engine control unit (ECU), the software may trigger the system to shutdown the engine during braking prior to a stop sign or traffic light, which could confuse the driver into thinking that it was planned by the Eco stop/start function.
However, the engine will not restart automatically after releasing the brake pedal, as the driver will need to push the ignition button. Due to this condition, the vehicles in question fail to comply with the National Highway Traffic Safety Administration (NHTSA) regulations and, depending on the traffic situation, there could be an increased risk of crash.
There are approximately 5,825 units affected by this problem, according to Mercedes-Benz USA, which have been put together from December 10, 2014, to June 6, 2016. Owners will be contacted by the manufacturer and after an appointment will be made with a local dealership, technicians will update the software. The repair will take just a few minutes and will be performed free of charge.
