“Since January of 2024, I been having issues with this vehicle. Check engine light came on after 3 day of purchase I was told it needs to be reset. From there vehicle emissions valve failed, N80 valve, electronic module and now fuel injection”
NHTSA complaint #11642859, filed 2025-02“EPC light comes on and vehicle starts losing power while driving, you lose all acceleration. Check engine light has also illuminated I have taken in to have repairs done on this same issue 4 times in a span of owing this car for 7 months, this vehicle has become unreliable and a safety hazard while driving. They have replaced battery replaced ignition coils replaced EVAP valve reset my computer software updated my computers. I have spent a ton of money on this car for a repair that is unrepairable. …”
NHTSA complaint #11744747, filed 2026-06“I have been having issues with the EVAP system in my 2021 VW Jetta. It has been in the shop at least 7 times since around 12K miles for the same issue. They have replaced all parts and upgraded the software several times and it is still an issue. My check engine light comes on and off all the time. It is just over a year old with almost 50K miles and they say that they are waiting on an update from VW and until then there is nothing they can do.”
NHTSA complaint #11497923, filed 2022-12“On steep hills the car automatically holds the brake for a predetermined amount of time, I believe 2.5 to 3 sec. I have a manual transmission car and when its time to move the brake assist won't release no matter what until the time interval is satisfied. The problem this creates is a stall issue. Its hard to coordinate when to depress the clutch and give gas. Too early and you lead to premature clutch wear or clutch overheating. Too late and the car stalls and you have to restart it. This is very because now you have to restart the car and can cause an accident.”
NHTSA complaint #11676370, filed 2025-07“I have driven my 2021 VW Jetta about 56,000 miles. Literally the whole time I have owned this car the check engine light has been on for an evaporative emissions issue. I have brought it into the dealer about six times. They have replaced everything associated with this system at least once and have done a software update. During my last visit, they reported that they had a conversation with VW and said “VW does not have a fix for this. We will let you know when they do.” I owned a diesel VW involved in diesel-gate scandal. This is the same, but different. …”
