My 2014 Tiguan, VIN [xxx], has been serviced at an authorized vw dealer since I purchased it. From 2014 to December 2025, the vehicle was serviced at a vw dealer and March 2026 to present at a service facility that only works on vws and is owned and operated by a prior vw certified technician who only works on vws. My vehicle has been serviced at all the vw recommended maintenance mileage. Looking back at the maintenance records, I can see that in March and August 2025, my vehicle experienced a check engine light issue that resulted in evap system small leak fault and vibration at start up caused by misfire cylinder. In April 2026, June 2026 and July 2026, I had to take my Tiguan in because I felt the engine shake, check engine light came on and power decrease. The vw technican replaced some components related to the turbocharger system in April and the check engine light turned off. The check engine light turned back on in June in June and July 2026. The technician stated the issue was likely a airflow flap within the turbocharger causing the issue and the entire turbocharger would have to be replaced to remedy the issue. I discovered the recent class action settlement on this same issue and shared it with my mechanic. His professional opinion was that the issues I was having were exactly what was covered in the settlement covering my vehicle but I had 94k miles and had to have less than 85k miles. So, I was not covered because of the mileage. But I believe the issues the vehicle had going back to March 2025, were all turbocharger issues. In any case, my mechanic reached out to vw to get assistance because of the mounting repair costs for me and for all of his other vw owners experiencing turbocharger defects. It is my hope that others have shared similar complaints in search of relief from NHTSA investigating the defective vw turbocharges. Vw has a negative track record on it's turbochargers.
