What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
There are alerts for the seat belt, air bag, truck/door opened, low gas, lights, etc. There is even a notification on the screen to remind me to grab my phone after I turn off the car and open the door.
On September 25th 2026, while driving my 2020 Volkswagen Jetta south on Route 12, the driver-front wheel completely separated from the vehicle while in motion. The vehicle suffered an immediate loss of structural control, and the undercarriage dropped directly onto the roadway, causing extensive mechanical, structural…
upon my mechanic's inspection of the vehicle for an unrelated issue, it was found that the entire subframe is rusty and corroded. He informed me that it was at a critical stage that would sooner than later lead to structural failure. Upon brining it to the VW dealer, they agreed with the assessment.
On 2 separate occasions (in recent 2 months); the car would not restart and error messages would include printing the electrical parking brake engagement. Attempts to reset were futile. Car had to be towed.
Volkswagen mandatory software update/campaign 24Fi corrupted the OCU/Telematics firmware on my vehicle. This firmware corruption deactivated the critical emergency SOS safety system (Automatic Crash Notification), leaving a persistent red fault light on the overhead console.
Car now rattles when it goes over bumps. Upon looking under the car, the right rear coil spring is corroded and snapped as well.
Fault electronic parking brake 3. Transmission in emergency mode you can continue driving 4.only exit vehicle in P position service engine soon Number 3 has shown before and I had another transmission put in. Also engine light was on for the longest. I'm not sure of the exact date.
My check engine light came on on Sunday Dec 1. I immediately took it to a diagnostic service station in my local area. They diagnosed that my car has a vent control valve malfunction. This issue is a KNOWN problem to Volkswagen. They do not replace this part if it fails after 60K miles. This makes zero sense to me.
