2021 Volkswagen Jetta

Mid June 2026 infotainment update was over the air software update. Update caused infotainment failures: looping screen resets, unable to play audio, disruption to screen during safety features such as back up cam, unable to accomplish directions, CarPlay no longer consistent feature. None of these listed problems were present before over the air software update.

Volkswagen corporate deployed a mandatory over-the-air (OTA) software update to the MIB3 infotainment system. The update failed mid-installation, entirely bricking the J794 information module. This failure completely disabled vital driver information systems, including the digital dash compass, all audio alerts, and driver notification tones while the vehicle is in motion. This represents an immediate, manufacturer-initiated distraction and safety hazard that disables cabin instrumentation.

While driving home from work last night, I heard a loud noise that sounded like a gun going off right in the passenger compartment of my Jetta. A lot of wind noise followed. I thought initially that a tire might have blown out, but it was the car’s sunroof that had spontaneously and inexplicably exploded. There was no one close to me on the road, so I don’t believe a foreign object struck the roof. I was able to drive the car home, but the sunroof is demolished.

Hill Assist system creates dangerous situations because it prevents me from moving right away while pulling out in traffic or in front of traffic lights, out of parking garages and stop signs. Hill Assist system often stalls the engine due to holding brakes engaged for an extended period of time even on a slight hill. With a manual transmission this makes it even worse because engine dies in these situations frequently. Dealer dismisses the issue because "there are no fault codes", but if it was manufactured incorrectly and/or calibrated improperly, no error/fault codes will come on. I have been driving manual transmissions all my life (from motorcycles to semi trucks) for over 40 years and it's clear to me that this vehicle is a safety concern with underpowered engine that cannot overcome Hill Assist. Other Hill Assist systems immediately disengage the brakes when an accelerator pedal is pressed. In this vehicle, the brake stays on and vehicle dies on even on a slightest hill. Please help investigate.

The car would not turn on while using the start/stop feature on three different occasions. Once at a stop sign when I wanted to reverse to make sure I was not pulled out too far into an intersection. I was stuck and could not get out of the way of a car coming. Each time I had to shut the vehicle off completely to restart the system.

I have noticed an issue with how easily the rear, passenger-side seatbelt is able to be clicked into the buckle. Initially when I got the car, passengers using that seatbelt did not seem to have any issue with easily clicking the seatbelt into the buckle. More recently, it seems my passengers using that seatbelt have a more difficult time clicking it into the buckle because the buckle seems to go down into the cushion when they put pressure on it. Passengers now have to hold the buckle in place while clicking it in. The only thing I can think of that could explain this change in how easily the seat belt can be clicked in could be that I put the seats down at one point using the pull lever in the trunk. I'm not sure this "ease of use" issue was the result of putting down the seats at one point but it's what comes to mind. This does not seem to affect the seat belt in terms of it being securely connected to the car, it only seems to affect how easily someone is able to click it into the buckle. People now seem to need to use two hands to click it in versus being able to do it with one hand.

This model Jetta seems to have an issue with the rear license plate mount. The rear license plate mount sandwiches the license plate between a plastic piece attached to the vehicle body and a plastic piece with branding specific to the dealership. The issue I have is when I unscrewed them to remove the top, plastic piece. After I tried to rescrew it without the top piece, it seemed like the screw holes were already stripped. Many people don't want to provide free advertising for the dealership and may attempt to remove the top, plastic piece this way. For safety purposes, you should be able to unscrew and re-screw them without stripping the screw holes.
