Electrical system

34 reports
“Vehicle threw SOS emergency call feature error two years ago. I replaced the module at the dealership. Today, the same SOS emergency call feature again showed up and I am unable to make an emergency call. This is a known and common issue with VW.”

Engine

26 reports2 crashes
“While driving my 2020 Volkswagen Tiguan (equipped with approximately 39,000 miles), the vehicle suffered a sudden and catastrophic total engine failure without prior warning, resulting in an immediate loss of power and propulsion while in motion. This sudden stall on an active roadway created a severe, immediate safety hazard and a high risk of a collision. The vehicle has been meticulously maintained with a complete and documented history of annual professional servicing. Prior to the failure, the engine repair light would frequently illuminate. Upon subsequent teardown and investigation of the failed engine, the authorized manufacturer dealership discovered heavy metal shavings in the engine oil, indicating severe and premature internal mechanical destruction of critical engine components. The vehicle has been diagnosed as requiring a complete engine replacement costing $9,000. A catastrophic mechanical failure of this nature at exceptionally low mileage, despite regular annual maintenance, points to a significant manufacturing or material defect.”

Structure

16 reports1 related recall
“The contact owns a 2020 Volkswagen Tiguan. The contact stated that while driving 70 MPH with two toddlers inside the vehicle, the ceiling of the vehicle detached and caused a bump on the head. A dealer was contacted, and the contact was informed that it was a known issue with similar vehicles. The vehicle was not taken to a dealer or independent mechanic to be diagnosed. The contact was informed that there was a recall associated with the failure but had expired. No assistance was provided. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact about an extended warranty. The approximate failure mileage was 110,738.”

Forward collision avoidance

16 reports1 crash
“I was driving and a vehicle was making a left hand turn, in the middle lane and they were in their lane and I was in mine, but the vehicle decided to use the automatic breaking which then cause me to have whiplash and it took a few seconds for the car to move and I had other cars behind me. Also, because this happened so quickly with no warning I first had to think did I hit the car, because I would have had no knowledge because the automatic stoping made noise and jolted me. So this is dangerous is all sorts of levels. If the other vehicle didn’t move and appeared to be fine and I had no damage to my car I would have not known.”

Visibility/wiper

10 reports
“The overhead console by the rear view mirror suddenly detached - only hanging by cords. It will not go back on. Duct tape will not even hold it. It is a safety hazard to drive it, and it impairs visibility. The dealership I took it to says this is a problem with 2020 tiguans, but I will have to pay for the repair.”

Service brakes

10 reports
“While Driving Breaks got hard to push and car system made “beep” alert with words “Break booster fault” displayed on instrument panel. Pulled over and error went away. Checked brake booster and lines. Can not get it to duplicate. Read on Volkswagen forums online that this is happening to others. Car shops unable to duplicate as well but reports online state that is has happened again after being cleared by Auto Shop.”
