Open the full vehicle complaint log (all categories)Hill Assist system creates dangerous situations because it prevents me from moving right away while pulling out in traffic or in front of traffic lights, out of parking garages and stop signs. Hill Assist system often stalls the engine due to holding brakes engaged for an extended period of time even on a slight hill. With a manual transmission this makes it even worse because engine dies in these situations frequently. Dealer dismisses the issue because "there are no fault codes", but if it was manufactured incorrectly and/or calibrated improperly, no error/fault codes will come on. I have been driving manual transmissions all my life (from motorcycles to semi trucks) for over 40 years and it's clear to me that this vehicle is a safety concern with underpowered engine that cannot overcome Hill Assist. Other Hill Assist systems immediately disengage the brakes when an accelerator pedal is pressed. In this vehicle, the brake stays on and vehicle dies on even on a slightest hill. Please help investigate.
