Volkswagen Atlas abs comes on

Filed Aug 14, 2026 · Electrical, Engine · LA

On multiple occasions at startup, vehicle made unusual sounds then either stalled shortly after starting or simply wouldn’t start. Vehicle has also stalled multiple times at red lights and stop signs. On these occasions nearly the entire dashboard lit up simultaneously with warning lights across many unrelated systems (“Christmas tree” effect), not a single isolated fault, often while on interstate at 70mph. Recurring, not one-time. 1.ELECTRICAL/ABS: Aug 2025, right front ABS wheel speed sensor replaced after dash lights loss + reported dying after startup; dealer couldn’t duplicate stalling. As of Aug 2026, scan shows left front ABS sensor faulting (open/short to ground, implausible signal) plus parking brake module fault referencing wheel speed sensor implausibility. Dealer also flagged left rear ABS sensor as Critical. Numerous low-voltage faults present across modules simultaneously (supply voltage too low, data bus implausible, control module input power low), matching dashboard cascade events. Battery replaced May 2024 after failing load test. 2.ENGINE: Dec 2024, cylinder 6 injector replaced (complete goodwill, dealer+VW corporate) for CEL/air-fuel imbalance. CEL returned next month for same fault; escalated to full cylinder head replacement ($6,054.95). 3.STEERING: Dealer inspection Aug 2026 flagged steering rack and pinion as Critical ($2,093.19), req. 4-wheel alignment. Confirmed with the federal safety agency/VW this vehicle is NOT subject to steering knuckle recall 21V026000/40Q7 — separate, non-recall defect. Requesting the federal safety agency review this combined pattern of stalling/no-start, cascading electrical faults, and critical steering failure.

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.

Circuit Malfunction- Faulty wiring causing ABS, and EPC damage and defects.

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.

I received a brake booster fault caution which was followed by the BRAKE warning light being illuminated. When I applied pressure to the brakes, it almost felt as if the ABS was kicking in, on a flat, dry road. The brake pedal would "jump" and depress farther on its own like there wasn't a good vacuum for the brakes. I've taken it to my local VW service center and was informed they had to call VW Corporate for assistance in a fix and was given a list of components to possibly replace that "may" fix the issue but even after replacement, some customers still experience the same issue. I am currently awaiting an estimate but have significant concerns that any repair work may not actually address the root cause of this issue and when it's related to a major safety feature like the brakes, that presents a significant concern.

Brake booster Faulty/Brake Booster Failure light displays on the dash along with the red Brake light and a loud beeping sound. The brakes feel shaky and the vehicle doesn’t brake well for about 30 second after. It feels as if the brakes are palpating or skipping instead of a solid grip. After about 30-45 second those lights go back off and brakes resume normal breaking but the ABS light comes on. This issue has happened twice so far and random times when not braking. It appears to be other reports of this issues in the 2018 models but not recall. Other year models have had brake issues recalled l. This is a major safety issue and should be addressed with Volkswagen to resolve it. This will and probably has cause accidents.

Today 3 times while driving my car braked on its own, emitted a loud noise and “Brake Booster Faulty” displays along with the ABS and Brake late. It also told me to power off the car. Prior to this there were no problems however I am now worried for safety reasons.

On [XXX] I was driving approximately 30 mph on a sunny, 83F day. There were no other vehicles around me, no pedestrians, no bicycles, no animals, etc. I was traveling south on a straight section of the road when my car came to an abrupt and complete stop. The car's automatic braking system was engaged without any prior warning. The car went from 30mph to 0 mph instantly. There was a loud beep, the red ABS indicator light came on, the wipers started operating involuntarily. The force of the momentum cause items to fly forward in the car. The seatbelt locked up. The force of the stop also caused whiplash and the belt tightening caused pain to my ribs and back. I was stunned and scared. Thankfully, no cars were around me and I was going 30mph instead of 70mph when I travel the highway most of the time. If someone was behind me or I had been traveling faster, the incident could have had grave consequences. I was next to a dentist office so I pulled into their parking lot slowly. I turned the car off and looked at the exterior. There was no indication that I had struck anything and there was nothing in the road that would have set the system off. Not even a leaf or bug. I had received a letter 2 days prior about a class action lawsuit against VW describing this same issue going back to 2017. I looked up what to do in the situation and everything online suggested deactivating that feature on the car. I turned the car on and deactivated it. I drove 15 mph to my office 0.4 mi away because I was scared it would happen again. I called my dealership and scheduled a diagnostic appointment. They couldn't get it in until [XXX]. They have had it overnight and have pulled data from it and sent it to VW in Germany apparently. Since I deactivate the feature before each trip, the problem has not happened again for me. There are many stories of this happening online but VW hasn't issued a recall at all and says it isn't an issue.

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.
