2021 Volkswagen Jetta service brakes problems

“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…”

“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…”

“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.…”

“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.”

“The rear brake pads on my 2021 Volkswagen Jetta have worn out prematurely twice by 20,000 miles. The first replacement occurred at only 8,006 miles in April 2023. At that time, Volkswagen acknowledged the problem and provided “goodwill” coverage of 50% since my vehicle was only one month outside of the Rear Brake Pad Limited Warranty Extension. Now at approximately 20,846 miles in September 2025, the rear pads have worn out again and required replacement. Volkswagen has refused to provide any assistance this time. Normally, front brake pads wear faster than the rear. In this case, the rear pads are failing far earlier than expected, which creates a potential safety issue since brake performance is being compromised at very low mileage. Volkswagen has already acknowledged this defect by issuing the warranty extension for 2020–2023 Jettas, but coverage expired by time, not mileage, leaving owners like me with repeated failures and no support. When I raised the issue with my dealership, they suggested that the premature wear is due to the emergency brake always being engaged when the car is parked. This explanation does not make sense, since pads do not normally…”

“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.”
