The investigation follows a December crash test.
The U.S. National Highway Traffic Safety Administration announced on Friday that it has opened a preliminary safety investigation into the 2018 Volkswagen Tiguan over seat belts that could potentially fail in the event of a crash.
The NHTSA's announcement follows a December crash test where the webbing on the Tiguan's driver's seat belt completely separated. The NHTSA is now looking into whether that incident was a one-off or a more widespread issue with the Tiguan's safety belts.
A Volkswagen spokesperson told Reuters that the company "will fully cooperate with NHTSA in the investigation and work to identify the cause of the different results between NHTSA's and our internal testing."
The 2018 Tiguan, launched last year, is a crucial new product for VW. In order to better compete in the hotly contest small crossover market, VW redesigned the Tiguan for the new model year with a longer wheelbase and an optional third row to appeal to American tastes.
