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

Start/stop error lightafter already replaced by dealership Brake booster faulty EPC light comes on-off randomly

- Big Spring, TX, USA

The vehicle will make a loud alarm and the dash will display "Brakes Booster Faulty". The vehicle then will brake itself regardless of where you are and brake pedal will not work properly. This could cause you to get rear-ended as the vehicle will simply stop!

I have had the same issue with this car since I-??ve bought it when. The issue is that often my dash beeps and says faulty break booster and then my breaks lock up and become spongy and the vehicle has issues breaking. Very scary and very dangerous. Then the -??break-?? warning indicator light illuminates and the vehicle eventually resets itself and goes back to normal functioning. My vehicle has been at the dealer at least four times during the warranty period for this exact same problem. It has also been there for a recall for rattling noises, air hissing out of gas tank when gas cap is unscrewed, and air conditioner going out. My car is currently in shop again for FAULTY BREAK BOOSTER. Others are having this same problem all over the internet. I want VW to honor me a manufacture buyback which I have already initiated the process for as my car meets the Louisiana Lemon Law Criteria-??s. I want VW to fix these problems on this model for future consumers as well. I have submitted all of my supporting documents to VWGOA

When starting the vehicle, the warning system will flash and display several errors, mainly "parking brake failure" and the light on the parking brake control will flash.Parking brake will disengage after several attempts and warning will go away. Problem started about 1 month ago and is becoming more persistant.

- Bristow , VA, USA

While driving on the highway, a warning flashed on the dashboard- FAULTY BRAKE BOOSTER. The pressure of the brake pedal was significantly diminished and was accompanied by a clicking sound. The red brake warning light illuminated. After 5 minutes, proper brake functioning was restored. Within a period of 20 minutes, the above sequence of events was repeated 3 times. After stopping and parking, the warning light went out. Upon start up later in the day, the same Faulty Brake Booster warning sounded and the brakes again were spongy and choppy. The following day, when driving to the VW dealership, the same message flashed on the dash multiple times and brake functioning was impaired.

- Chicago , IL, USA

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.

- Pacifica, CA, USA

At random time, during slower speeds, many vehicle would -??jerk-?? mad produce a Brake Booster Faulty warning and the brake light would illuminate on the console. The brakes would then become -??spongy-?? and difficult to operate. The light would stay in, or turn off after a while and driving would resume as normal. Difficult to replicate but scary how random it is.

- Santa Maria, CA, USA

I was driving on the highway around 60 mph. Without warning, my car's brakes fully engaged. There was no car or object ahead of me. A warning light that had the words "Brake Booster" was displayed but I couldn't make out what else it said as I was trying to regain control of the vehicle. Thankfully, there was no one behind me otherwise this could very well have resulted in a high-speed accident. The car went from 60 mph to around 20 mph. I pulled off the side of the road as quickly as possible.

My vehicle has completely just shut down atleast five times since owing it. I have a special needs son who is in the vehicle with me all the time. The vehicle engine will shut down with no warning and not restart. Traffic behind me not aware that my vehicle has shut down after the light has turned green. It has shut down at various times in the middle of traffic. I-??m fearful for myself and child that an accident is just a matter of time. I read complaints from others who state they have experienced the same problem. I-??m concerned for the SAFETY of others and me and my son. No warning is given before it just dies. I don-??t feel safe in this vehicle. This vehicle needs to be FIXED immediately. My vehicle has approximately 38,000 miles on it currently. This occurred either when I have stopped completely at a light, or when trying to start up the vehicle. Respectfully, VAP

- Mathewd, AL, USA

My vehicle Beeps loudly and says -??BRAKE BOOSTER FAULTY-??. My brakes become spongy or hard to engage and I usually have to start the car over again. This has become a frequent issue and I-??m afraid to drive my vehicle now. I-??ve tried to catch a video but I can never get my phone out in time.. I am shocked that this is a common issue and it has yet to be recalled.

- Spartanburg , SC, USA

While driving, the instrument cluster will light up with red warnings about the braking system not available, I remember seeing "brake booster" in the warning, and need to pull over immediately. At that point, it feels that I have lost the brake booster and I need to step on the brakes very hard to stop. It is scary, as it occurred while driving in the city, with speeds from 30-35 mph and cars behind. It has happened 3 times over 9 months. It is not easy to reproduce as I don't know what causes it. Whe it happens again, if its safe I will try to take a picture as well. Similar people have had the same issues: https://www.vwvortex.com/threads/brake-booster-faulty-alert-while-driving.9175137/

Could not brake my car today with 2 children in backseat. Very dangerous.
