Hill Start Assist?
My Sister just bought a 2015 Spark 1LT. When you stop on an incline (facing up), and then let off the brake, the engine does not respond to the gas pedal. It coughs, stumbles, etc., for a few seconds, then catches. At times, it almost totally quits. Is this related to the "Hill Start Assist"? Is this normal behavior? If so, is there a way for the dealer to disable this feature?
