2021 Volkswagen Jetta Driver assistance Problems

While traveling at the posted speed limit and approaching a signalized intersection, I attempted to brake for stopped traffic ahead. The vehicle did not decelerate as expected, and the automatic emergency braking/forward collision mitigation system did not activate or provide any braking assistance. Additionally, no forward collision warning or audible/visual alert was provided prior to impact. A red warning indicator illuminated immediately before the collision; however, there was insufficient time to take additional evasive action. As a result, my vehicle rear-ended the vehicle stopped in front of me. The apparent failure of the braking assistance and forward collision warning systems placed both myself and the occupants of the other vehicle at risk, resulting in a motor vehicle collision. The vehicle is available for inspection upon request. The cause of the malfunction has not yet been confirmed by a dealer or independent repair facility (UNKNOWN). The vehicle has been inspected by law enforcement and insurance representatives as part of the accident investigation. Prior to the incident, I had not observed any warning lamps, messages, or symptoms indicating a problem with the braking or forward collision systems. The only warning observed was the red indicator light that appeared immediately before the collision.

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.

Under 20,000 miles, but over 1 year old (leased new february 12, 2021). VW dealership and secondary party reported rear brake pads and rotors were worn down to 1mm and that the car was unsafe to drive. This cost $500 to repair and I had to pay it for a car that was just over 1 year old. The dealership wanted to charge double to replace. The brakes are only warrantied for 1 year, and because most don't hit 20k miles for a year, they know that the parts are unsafe and will wear down at 20,000 miles (as reported by many many others for the 2021 VW Jetta). I have receipts of inspection and for part replacement by Brakes Plus. There were NO warnings, just the tires squeaking when the weather got cold in December. Also, ABS issues - car stalled twice in the middle of a busy street in the first 6 months of use.

Upon backing out of a parking spot a vehicle approached at a fast rate of speed. The rear cross-path sensor and emergency braking activated. This action caused the brake line to rupture and the brakes failed on the vehicle. I resumed reversing out of the parking spot and put the vehicle into Drive. Once I applied the brake, the pedal went to the floor with total brake system loss. The vehicle was towed to Armstrong Volkswagen in Gladstone, Oregon. The dealer found the rear passenger side brake like had ruptured due to it rubbing on the fuel filler neck shield. The sudden increase in brake line pressure caused the final failure of the brake line. The brake line was repaired under warranty. This could have been a significant life threatening situation had I been traveling at high speeds and the brake system failed (i.e. exiting an Interstate, etc.).

I've had 3 manufacturing defects on my 2021 VW Jetta, with 18,000 miles currently, the first issue was my sunglasses compartment on the ceiling of the car, the plastic latches broke by itself, The second issue my car had, multiple sensor lights went off simultaneously, shortly after my breaks started braking by themselves randomly, The dealership were I purchased the car, Payne Mission Mitsubishi Volkswagen, 2003 E Expressway 83, Mission, TX 78572 told me to leave the car at the dealership and maybe they could fix it in a month, I told them it was my primary car that I couldn't do that, they said well to be in line the car had to be physically present at the dealership, I thought about suing for breach of contract for refusing to fix it and giving me the run around, The 3rd Manufacturing defect that I had with the car, The front panel glass part number #17A8770559B9, shattered spontaneously on a rural highway with no one around me, it sounded like a gunshot when it exploded, The dealership and VW have refused to acknowledge that it is a manufacturing issue, I'm currently waiting to see if they will cover it with factory warranty, but I've been getting the run around. I'm aware that VW already had this issue brought to their attention several years back when they were sued, they have not resolved the issue. I'm asking for an immediate recall of their front panel glass and sunroof glass that was cheaply made and manufactured in Mexico. they are charging us 895$ MSRP for glass that's defected, part number #17A8770559B9. I was told by a VW Customer Service representative that a VW engineer would have to examine the glass. If your organization is unable to assist me my next course of action will be to fight this in court till the end, this is an injustice to the customers, an organization as big as Volkswagen should acknowledge the issue and address it in a courteous manner, their should be more laws/rules in ethics when it comes to car sales and mechanic shops.

The car suddenly warned and stopped abruptly while we were traveling over a steel plate on the road. There were no other hazards in the road and no other cars in front of us in our lane (there were cars oncoming in the opposite traffic lane, but none had crossed over into ours). While we were impressed by how quickly and effectively the car stopped, we are concerned that the car may have deemed the steel plate to be another car or other road hazard. Had the person behind us been traveling too closely or at a higher speed, we could have been rear-ended. In this scenario we were OK, but had this steel plate been on a freeway it could have caused a serious accident.

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.
