2021 Volkswagen Jetta Electrical Problems

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.

What system component failed or malfunctioned? Is it available for inspection upon request? The car boards are left inoperative. If the entire car loses power Don't grab the car How was your safety or the safety of others put at risk? I'm driving down the road and suddenly the car no longer works. It doesn't start and the drivers behind me have to avoid me. On many occasions I have had to leave the car on while I run errands because I have had to ask for help to turn it on, so I don't turn it off because I don't know if it will turn on again. And this is a dangerous practice since they can steal my car and what I have inside since I have to leave it on. Has the problem been reproduced or confirmed by an independent dealer or service center? Every time I bought it and took it to the dealer, they indicated a different fault. At first they indicated that it was the electrical part and they made changes to it. Then apparently it was the battery but it was not safe. They have taken it apart several times but have not been able to fix it, since each time it seems to have a different error. The last scan showed a ground short circuit. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? I have always taken the vehicle to the dealer who sold it to me. Were there warning lights, messages or other symptoms of the problem before the failure and when did they first appear? The first time he took it was because the dashboard went out, the electrical part was left not working. If you are unsure, simply indicate UNKNOWN and provide your best assessment of the incident and cause in your description.

When I started my car a light came on saying “check starter system” and I turned the car off and then turned it back on and same message appeared. I waited until it was cooler outside and tried it again and the light disappeared. I’m aware of the recalls on the 2019-2020 Jetta and the faulty ignition switch, and I believe this is what it is as well.

When I started the car an alert came on the said the door there was a driver door contact switch error. When I was trying to back up the emergency brake came on. The door was closed. There was an electric parking break error. Also a start stop error. When trying to go forward the parking brake kept coming on. I was going 10 mph and the e brake engaged and would not let me out unless I turned off the car and turned it back on. When I brought it to the dealership they ran tests on it and they said it was the door wiring harness. There is problem with it and IT IS NOT SAFE TO DRIVE. When driving around corners it also has a tendency to want to depart you from the lane. It will try to kick you out of the lane even if you are in the middle of the lane. It has done this around corners and when driving straight. It caused my sister to be driven off the road. This has been brought to the dealerships attention and they found a problem with the lane departure and told me that they could fix it and then they came right back and told me that there was nothing wrong with the car.
