Was driving on the freeway in my 2019 VW Tiguan when I experienced a sudden unexpected loss of power. Warning lights came on and the car went into a "limp mode" not allowing the engine to rev past a certain RPM. I took the car to be serviced at a local dealership where it was determined that the Fuel Injector Harness was faulty and needed to be replaced. When I informed the dealer that there was an extended warranty on the harness (2018-2019 model years within 10 years/120 miles) and the part should be covered, the dealer and later VW of America said that my vehicle was not part of the warranty. VW of America could not explain to my as why my car was not part of this warranty, but it is obviously a known problem on their end and they should honor what they advertised with their warranty extension with the NHTSA. [XXX] I find VW of America's response to this problem completely unacceptable and quite dangerous. Their unwillingness to take care of this critical component with a known failure rate unnecessarily costs consumers for repairs that VW should be honoring according to their own posted Warranty Extensions and could potentially cost bodily damage and lives. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Gear shift from gears 1 to 2 or 2 to 1, the gears often “slip” resulting in a slight delay or jolt upon acceleration. This is an ongoing issue that occurs frequently, for years.
