There is a known issue released by Volkswagen that certain model years of their vehicles are eligible for a limited extended warranty regarding the clock spring. In their release announcement VWP-18-11 on April 27, 2023, they specifically mentioned vehicle year model 2010 to 2022 qualifies for U37 Warranty key if the issue exists. However, my 2021 Volkswagen Jetta is excluded from this because they told me there is no identified issue as of now. However, the clock spring damage can lead to a severe safety concern that the driver's airbag won't be triggered and the front alert is not working properly as well. Taking these into consideration, Volkswagen still declined my request to offer the limited warranty they offerred to other vehicle that has the same problem.

There appears to be a known issue with the rear braking system on the VW Jetta for various model years including 2021. The issue seems to be a combination of soft brake pads combined with the autonomous braking system which overuses the brakes and causes premature wear. This rear autonomous braking system cannot be turned off. VW acknowledged this issue by issuing Policy and Procedure Bulletin VWP 22-18 on 12/20/2022 which extended the warranty on the rear brake pads to 2 years or 24K miles. This extension was due to a premature wear issue though they did not acknowledge in the bulletin that the autonomous braking system was to blame or faulty. I had to replace my rear brakes and rotors at 25,100 miles and have now been told I need to do this again at 47,800 miles. I paid over $500 the first time and have been quoted over $600 this time. I believe VW is aware that the rear braking system is faulty and is causing excessive wear to brake pads and resulting damage to rotors. This premature wear could lead to a safety issue if the rear brakes do not function as needed. I believe VW should issue a recall for the rear braking system and fix the issue rather than force consumers to keep replacing pads/rotors every 24K miles. I will attach the service bulletin from VW along with my invoice for replacing my brakes at 25K miles and the estimate to replace them again at 47,800 miles.

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.

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 the federal safety agency and reported on consumer safety platforms describe the identical pattern.

I took my car into dealer at 20,000 miles. They told me rear brake pads and rotors needed to be replaced. At that time, they were replaced under warranty. I took my car into dealer at 34,000 miles for regular service and was told rear brake pads and rotors needed to be replaced. Pads were at 3%, service associate warned me about driving on the highway. I took my car to another location and mechanic for a second opinion and was told "rear brake pads approx. 2mm remaining friction material, and brake rotors are overheated & scored. Not knowing that my rear brakes had worn down to this level in 14,000 miles put myself and other drivers at risk. I had no warning nor did I experience any symptoms in my brakes until I took it in for regular service.
