What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Dash and infotainment center lights flashed and shut off. Vehicle rolled backwards uncontrollably down a sloped driveway. Steering and brakes were not properly functioning. Vehicle came to a stop when it struck a parked vehicle in its path.
On 4/6/24 the steering wheel locked while driving the car . Causing the car to go off the road into a 40 ft ditch and hit a tree
A software update from Volkswagen causes the infotainment system to crash and become unusable and no longer functions. Car owner is forced to purchase a new infotainment control system which is back ordered nationally with no estimation of arrival.
An engine light had come on in our vehicle, and we brought it in to the dealer to find out why. They could not find any reason that the light had come on, and said everything was fine, but that they did find that the rear spring was broken.
The high pressure fuel pump has failed within 40,000 miles and now again at 110,000 miles. It causes the vehicle to randomly turn in drive and while idle. It has had oil consumption issues and oil leak issues that constantly occur.
At 58,218 miles, the engine on this 2021 Volkswagen Tiguan failed after excessive oil consumption progressed to engine knocking. The vehicle was brought to [dealer] on July 24, 2025, for excessive oil consumption. The dealer performed a second oil-consumption test. During the test, the engine was heard knocking.
2021 Tiguan parking brake comes on without being commanded. There is a fault with the drivers door. I believe the the driver door module or corresponding wiring. The front drivers window toggle switch does not work the toggles switches for the rest of the window work only if the is not an error displayed on the dash.
Upon restarting the vehicle, the electronic power control (EPC) warning light and the yellow triangle for the central warning light illuminated. The vehicle was idling roughly and jerking while driving to the dealer.
