What Owners Say
"Repair under warranty to my complete satisfaction."
Anonymous A., NC (2018 Volkswagen Tiguan SEL 2.0-L 4 Cyl turbo)"The problem started gradually as an occasional "hiccup" while driving. My wife brought it to the dealer--a mechanic drove it and said that there was nothing wrong. We then took it on a trip from SE Texas to Northern Kentucky. In far Western Kentucky, an EPC error appeared with the message that the car was running in "limp mode." We were on an Interstate at the time, but luckily near an exit. AAA towed us to the garage in the small town that we were in. By the time the garage had the car, the error had disappeared and the car ran normally. The owner took it for a test drive and duplicated the problem. They tested the car while it was still running and found out that it was the #3 injector. We had to stay overnight while they retrieved the part from a dealership in Tennessee and had the car repaired the next morning."

Anonymous, CA (2018 Volkswagen Tiguan 2.0-L 4 Cyl turbo)"I had to replace all the fuel injectors in 2022, which I paid out of pocket. And just recently had to replace a wire harness for the injector which VW does have an extended warranty recall, so this was covered. They also updated my computer to change up the sequence of the power trans. VW knows they have issues with their Tiguans injectors and their harnesses along with all their transmissions (all of their vehicles to be honest have issues with rough and/or sticking shifting, I had a brand new 2015 GTI before my son was born and it too had hard shifting and sticking with the transmission)."
