From owner reports, verbatim
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.
Vehicle Information: Year: 2021 Make: Volkswagen Model: Jetta Date of Purchase: March 2022 Approximate Mileage at Time of Incident: 25,000 miles --- NATURE OF COMPLAINT: I am filing this complaint regarding premature and dangerous rear brake pad and rotor wear on my 2021 Volkswagen Jetta, purchased new in March 2022. At approximately 25,000 miles — well below any reasonable expectation of normal brake wear — I was informed by a service technician that my rear brake pads required immediate replacement due to excessive wear. The front brakes showed no comparable wear, which is inconsistent with normal braking patterns and strongly suggests a manufacturing or design defect. SAFETY CONCERN: Premature rear brake failure at such low mileage presents a serious safety hazard. Degraded braking performance increases stopping distances and reduces driver control, particularly in emergency situations. I was given no prior warning indicators or alerts from the vehicle's onboard systems before being advised the brakes were critically worn. This lack of advance warning compounds the safety risk. SUPPORTING EVIDENCE OF A KNOWN DEFECT: This is not an isolated incident. Volkswagen has already acknowledged premature rear brake pad wear as a systemic issue in 2020–2023 Jetta vehicles by issuing a Rear Brake Pad Limited Warranty Extension, extending coverage from the standard 1 year/12,000 miles to 2 years/24,000 miles. Despite this acknowledgment, Volkswagen has refused to provide adequate and lasting remedy to affected owners, and many consumers — including myself — have been denied reimbursement or further assistance after the extended warranty window expired. Notably, my vehicle reached 25,000 miles just outside the extended warranty coverage limit, yet exhibits the exact defect the warranty extension was designed to address. Multiple complaints filed with NHTSA and reported on consumer safety platforms describe the identical pattern.

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.
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.

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. And it currently sits in the VW dealership shop again because it is become a safety hazard to drive with myself let alone putting my child's life at risk driving on highways.
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.
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.

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
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.

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.

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.

The contact owns a 2021 Volkswagen Jetta. The contact stated that while driving at an undisclosed speed with adaptive cruise control on, the vehicle inadvertently applied the brakes completely bringing the vehicle to a complete stop in the middle of the roadway, after which the vehicle then shifted into the parked position. The contact also stated, that later while driving at an undisclosed speed, the vehicle suddenly steered itself to the left towards oncoming traffic before the contact was able to regain control of the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The contact was informed that the manufacturer was aware of possible issues with AI driving. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was not available.
When driving the vehicle, the steering wheel while jiggle violently while an electrical noise is heard. This happened while driving on the interstate at 70 mph and I had to hit my breaks as I was fearful I didn't have control of the vehicle. It then continued to do it even at lower speeds. The vehicle has been to a service department where they state the steering rack and pinion has failed. There are no warning lights, lamps or messages. The vehicle is at 72k miles.

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.
1.It's not stable to drive in highway. Problem starts at around 55mph. 2. When I stop in traffic light suddenly rpm goes up and car jumps forward. It happened several times. The car was warm and in drive mode. I'm sure it shouldn't do this. Now when I stop in traffic light and pedestrian crossing in front of me, every time I put it to neutral and hold brake, in other ways just holding brake sometimes can not stop the car. If someone calls me I give more details.
