2019 Volkswagen Atlas: ABS light or ABS activating

Filed Mar 10, 2026 · Brakes, Electrical · FL

Component Failed: ABS Braking System / Wiring Harness. Safety Risk: While driving at highway speeds with my service animal, the vehicle suffered a catastrophic ABS failure. The brakes became unresponsive, and the dashboard displayed multiple critical safety warnings, nearly resulting in a collision. Confirmation: The failure was confirmed by Schumacher VW (West Palm Beach) during a forensic inspection. They identified the cause as a corroded/damaged wiring harness—the exact defect visible in a diagnostic video from Jim Ellis VW one week prior. Warning Symptoms: "Front Assist" and sensor warning lamps appeared on [XXX]. I paid Jim Ellis VW for a diagnostic; however, they failed to repair the visible defect and later falsely denied to the BBB that the diagnostic ever occurred. Summary: This vehicle (VIN: [XXX] ) has a documented safety defect that was identified by a technician but concealed by dealership management. This concealment led to a total loss of braking assist while the vehicle was in motion. The vehicle is currently available for inspection at Schumacher VW. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting a critical safety failure of the ABS wiring harness following service at Jim Ellis Volkswagen. I originally brought the vehicle in for a "Front Assist" safety light diagnostic. Immediately following the service, the ABS wiring harness failed, disabling my braking safety systems. The dealership is currently withholding the diagnostic report and technician notes that would confirm the state of the wiring harness during their inspection. This failure has rendered the vehicle undriveable and creates a severe safety risk to the driver and public.

The ABS or AES malfunctioned while driving. The brakes were automatically applied, without warning, with a medium amount of traffic and vehicles behind me. This poses a significant safety issue to myself and others when the brakes get applied without warning. A vehicle behind me had to swerve to avoid rear-ending me and others had to go around me on an onramp to the highway. I am taking my vehicle to Volkswagen of Waco today to have this issue looked at. I am also looking into a dashcam to see if I can get the issue on camera in case the dealership isn't able to duplicate the issue. This issue has occurred other times, this has not been an isolated incident. I do get a faulty brake booster light while the vehicle is braking so there is no warning before it happens, just me flying into my steering wheel.

While driving approx 20MPH while turning a corner in a neighborhood, the FAULT BRAKE BOOSTER warning went off and braked my vehicle. The car continued to flash this warning and the brakes were not easily depressed (felt somewhat like when ABS happens in icy roads). This happened multiple times until I could get home.Took the vehicle to VW dealer and they replaced a sensor. 3 weeks later the same warning and braking situation happened while in a parking lot. Returned to dealer and still being evaluated. Online, this is a recall for 2019 Atlas' but not for my VIN. Concerned this should be included in a recall. Worried for my safety as this has happened multiple times including after repair and causes the car brakes to go automatically and unexpectedly.

I was driving on the freeway on 10/13/2023, it was raining and I was startled by an alarm and a flashing warning on my dash stating brake booster failure, the abs light went on and I was concerned because I recently had by brakes done at the Volkswagen dealership in Brooklyn Center Minnesota on 10/4/2023. I was afraid of not being able to brake and I pulled over and put my car in park and I received a park assist failure warning on my dash as well as the park assist light turned on by the shifter. I shut my car off and called Volkswagen in Brooklyn Center. I was assured that my brakes wouldn’t stop working and the service tech was unaware why the red light near my shifter for the park assist would turn on by itself. The dealership was about to close and I was told that I could maybe be squeezed in on that following Monday and eventually was scheduled. I restarted my car and received another error for the electronic stabilization control. I called back the dealership and was able to catch the tech before he left and I was concerned about driving it. I was told, you are basically driving a 1985 Volkswagen, be aware you don’t have the safety features. My car was reviewed on 10/24/2023, I was provided with a rental car and was told the problem was the abs electronic braking module that this is known to go out at my mileage. I do see that others have had this issue and there was a recall, but I was told my VIN number was not included. Prior to this I did report driving in a mall parking lot and I had an alarm go off for a collision warning and my car suddenly braked on it’s own and no vehicle was around me. I have also been in slow traffic and periodically had the collision warning go off and the vehicle was a good distance in front of me. I was told that that can happen with the sensors. I’ve also been driving in the winter and I’ve gotten the warning look that it’s safe to move alarm alot when I’m stopped in traffic, I’m guessing that it’s due to ice near the sensor.

At random times, at random speeds, my instrument lights will illuminate with a beep and display the brake light. Sometimes just the brake icon, sometimes the brake and ABS, and sometimes both along with the engine light. At the same time my vehicle will violently brake on its own. When I depress the brake pedal to gain control the pedal is "jerky", rigid, and difficult to push in. Sometimes this lasts for a moment, sometimes longer. This is very dangerous and seems to occur more frequently. A 'Brake Booster Faulty' message appears on the dash.then dissappears

Suddenly Warning lights illuminate- Brake Booster Faulty, Start Error, ABS. Brakes then feel spongy, jerky hard to slow down and stop safely. Vehicle then needs to be towed to dealership for repair - vacum sensor C10A301 replaced. This has happened three times 4/22/21, 8/5/21 and 6/7/23. Dealership claims to need the part for refund from VW for warranty repair. This is a dangerous situation and needs to be remedied, especially as this is a family car.

ABS and Brake warning light come on dash making the break pedal click, causing the car to break abruptly or lock. Usually happens while at a complete stope or if driving below 30 to 20 miles an hour.

While driving( multiple scenarios ranging from 10 mph, 70 mph, 30 mph and even while car was parked) alarm would go off and message displaying “brake booster faulty” while also illuminating the “brake” light on dashboard. Brake pedal then becomes stiff and/or spongy, while not working properly. Once car is turned off and back on, “ABS” light is also illuminated. Could not brake my car today with 2 children in backseat. Very dangerous.

On eight occasions this morning the faulty brake booster light has come on and the ABS light and brake light are also on inside my vehicle. The brakes are squishy and almost don’t feel like they work to 50% capacity. They are jerky and click and does not seem like a simple antilock braking system problem. This is happened randomly over the last three years that I’ve owned this vehicle. But it has never happened this many times consecutively in the short period of time. I’m afraid for the safety of driving this vehicle.

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle had a warning come up on the dashboard, the warning was as follows: “Brake Booster Faulty”. The brakes then felt like ABS was engaged (brake pedal pulsating) and the brakes fully engaged and took the car to a full and complete stop from 20 miles per hour. After turning the car off and back on the warning had gone away and we continued on. The warning then came on two additional times during the same trip and instead of stopping the car, the brakes would pulse and not work as well as should be expected. How was your safety or the safety of others put at risk? Brakes did not work as expected and slammed themselves, had this occurred on the freeway that could have caused a pile up. Has the problem been reproduced or confirmed by a dealer or independent service center? No, but it has happened on multiple occasions and the dealer told us it was fixed previously. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Currently being inspected by the dealer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? As noted the “Brake booster faulty” error flashes on the dashboard when this problem occurs.
