NHTSA Complaint #11619701 — 2022 VOLKSWAGEN TIGUAN

The powertrain control units (engine and/or transmission) exhibit concerning behaviors when accelerating from a stop. The actual vehicle acceleration and propulsive torque does not match driver demanded torque for an extended period of time. The amount of delayed reaction is longer when the vehicle is ‘cold’ meaning that the vehicle has not been running prior to driving for an extended period of time. There is some amount of initial acceleration that allows the vehicle to move into the road but then the propulsive torque seems to go away completely for 3-4 seconds. The torque delivered after this delay is then exponential which is again not matching what the driver is asking for. The unintended torque can put the driver at risk of being in a lane without the ability to accelerate out of danger in time. For the situation of having too high of torque can put the driver in danger of hitting an object because the driver was not planning to accelerate so aggressively. These two behaviors can compound on each other as well. When the driver experiences the too low of drive torque condition, the driver could apply more throttle to correct but this will only make the too high of drive torque condition worse. These behaviors occur after every drive-off from standstill. There is a TSB to help improve this behavior. There are no active faults or warning lamps. Many other owners and dealerships confirmed this same behavior. The occurrence date was set to the date of this complaint but these behaviors have been occurring since date of purchase of vehicle.
