I have experienced an alert/alarm for a "Faulty Break Booster", "Break System Failure", as well as other Break related alarms go off while driving. Multiple times I have been going over 40 mph and the vehicle has instantly breaked and came to a stop on it's own. I have taken my vehicle to the dealer and was advised there is no issue. This issue seems to happen randomly as I have been unable to recognize any similarities between conditions and frequency.

When starting up my vehicle the battery turns on but the engine will not start. My dash will light up with multiple warnings. These are the specific ones that warn me: Error: electronic stabilization control (ESC) Error: hill hold assist BRAKE - Brake booster faulty ERROR: Hill hold assist Front assist not available. ERROR: tire pressure monitoring system. Trans. in emerg. Mode. You can continue driving. FAULT: electronic parking brake. Eventually my car starts up, but this is after several attempts. Once I shut car off and go to start back up, it goes through the whole process again. My car was taken into Volkswagen dealership and they said it was my fuel pump, fuel filter & battery. They “fixed” that but by the time I drove my car home, the issue started back up again. My safety is 100% put at risk because not only does my car not start up right away but I can be driving my vehicle and it will slow me down on a main highway and make me brake and then I need to attempt to restart my car to get it started up again several times. I have children I drive around in this vehicle and it is not safe to drive. My car has been illuminating the check engine light and all the other ones for each error I stated above. The problem itself has not been identified. When I did research, the 2019-2020 VW Atlas’s were recalled for this same issue it seems. But mine wasn’t because it is a 2018.

While driving, the car suddenly slowed to nearly stopping and a "Brake Boost Faulty" red warning light displayed on the dashboard. I was not breaking at the time. The brake pedal felt soft and the car would not regain acceleration. I had to stop the car, turn off ignition, restart for the car to drive normally. This occurred twice once while driving over 40 miles per hour and again at approximately 25 mph. IN both cases I was not braking when the incident happened.

Our 2018 VW Atlas will randomly shut the engine off even with auto start/shut off disabled. This has happened 5 times in 3 months. It has done so on the highway and on main streets putting our family of 6 at risk of being in an auto crash every time. The brakes have automatically came on 2 times. Forward collision sensors come on with nothing in front of us which also puts the breaks on and makes a distracting loud beep which has made me jump out of surprise while driving. The EPA rated fuel economy is 26 highway and 22 city. We drive both and rarely get above 16 combined MPG even with multiple drivers and making an attempt at getting better economy. Our Atlas also makes a loud “clunk” sound from the undercarriage in the center/rear of the vehicle. It does this while driving or while parked with the vehicle idling. Also not major but sometimes when the front passenger window is half down, if you push the button to roll it up, it goes all the way down. We are going to take it in to VW soon but there is a lot wrong that either make driving it a hazard to ourselves and other drivers and makes us feel very uncomfortable. We love it but we are also afraid of it. There is currently no open recalls. I’ve been a mechanic, a machinist and an engineer for nearly 20 years. Some stuff just doesn’t make sense. I read the crank and cam pulses, usually you’d expect a drop in pulse that could cause the engine to shut down but there’s nothing. Nothing on the scan tool or on the onboard vehicle diagnostic.

When braking normally, the AEB alert tone sounded, and the display showed a red BRAKE warning with "Brake Booster Failure" displayed on-screen. The brakes then became extremely sensitive and caused the car to abruptly grind to a stop with full ABS action. This occurred in traffic, and the car behind me narrowly avoided a collision due to the uncommanded abrupt halt. I pulled over and the error cleared itself after a few seconds. I pulled the diagnostic error codes from the ECU, and this is the output: 0213 [0x0000D5] Archive (inactive) C10A329: Vacuum sensor, Implausible signal Single Vacuum Pressure Sensor sends no valid data Status bits: 1 Priority: 1 Frequency: 1 Unlearning index: 84 Odometer: 27031 km Date, time: 2023.03.27 09:34:50 Paramteric values: 00 00 80 18 32 00 00 00 CF 47 00 00 02 FF 00 5E 02 40 B0 00 00 00 10 Status: Confirmed (This is from a previous activation, but the recent one is the same). This is the third time this has happened, but the first to put me in actual danger of a crash. I have previously brought this to the dealer but no fix was applied. They were aware of this happening on other vehicles but they did not have a fix. The model year after was recalled due to wiring issues, but my car has never been recalled for anything related. I believe this is a significant safety issue and should be addressed by the manufacturer before it causes a serious incident.

What component or system failed or malfunctioned, and is it available for inspection upon request? The front brakes unevenly wore to the point where the driver side brake is like new and the passenger side brake is a safety issue. How was your safety or the safety of others put at risk Because of the extreme wear on the passenger side braking system the whole front braking system needed to be replaced prematurely to ensure safety. Has the problem been reproduced or confirmed by a dealer or independent service center? A simple Google search shows that this is a common issue with the 2018 VW Atlas. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was inspected by the manufacturer, but VW insists there is nothing wrong with the components despite not being able to explain why the passenger side front brake was so significantly more worn than the driver side front brake. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. This was identified during an oil change. I was told that it was a safety issue for me to be driving on a front brake that was so worn. When I brought it in for the brake work, I suggested there was a defect in the design and the brake replacement should be covered by the warranty. I was then informed that I really didn't need to have my brakes replaced at this time.

These vehicles are equipped with either a 3.6 or 2.0 liter engine. The subject investigation concerns vehicles equipped with 3.6L engines. Prior to opening the investigation, ODI also observed that warranty data for the fuel system from TREAD reporting was an outlier for the MY 2018 Atlas.The allegation involved fuel injectors leaking fuel near engine compartment components that operate at high temperatures. Consumers allege a fuel leak, fuel odor, and/or an illuminated check engine malfunction indicator light (MIL) on that alerts them to the condition. Fuel leaking in the engine compartment has a higher potential risk of fire as nearby components are operating at higher temperatures compared to other areas of the vehicle. No fires have been connected to this issue to date.The 3.6L engine is a VR6 type engine. Due to its specific design, the VR6 has two types of injectors with different designs installed. Cylinders 1, 3, and 5 use long injectors and cylinders 2, 4, and 6 use short injectors. Unlike the short injectors, the long injectors require an extension pipe necessary to reach cylinders 1, 3, and 5. Volkswagen stated that the potential root cause for a leaking injector is typically either a damaged, misaligned, or missing supporting ring or a damaged O-ring. These rings assist in connecting the injector to the extension pipe. If one of these conditions is present in a vehicle, the O-ring has difficulty withstanding fuel pressure over time.Volkswagen stated that an analysis of warranty data related to leaking injectors in vehicles equipped with 3.6L engines showed that the vast majority of leaking allegations were related to internal leaks. Fuel can leak into the cylinder causing misfiring in the affected cylinders. This condition would not cause fuel to enter into the engine compartment. Volkswagen states that these internal leaks pose no unreasonable risk to motor vehicle safety.Analysis of all relevant data indicates that the subject condition is an early-life failure with a relatively low failure rate. The average failure mileage calculated from all data sources was determined to be approximately 14,000 miles. Only two failures were reported outside of the vehicles' warranty coverage period. The average time to failure for the subject vehicle population is approximately 12 months in service (MIS). The majority of failures were below the average of 14,000 miles or 12 MIS. Analysis of reported failures showed that the failure rate is approximately 0.08% or 0.8 incidents per thousand vehicles (IPTV).To date, there have been no reported fires, crashes, injuries, or fatalities related to this issue. In view of the low rate of failure, the nature of early-life failure, and low potential hazard to drivers, this Preliminary Evaluation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.Review the ODI reports cited above at nhtsa.gov under the following identification numbers:11446833, 11438403, 11382958, 11298402, 11291955, 11218819, 11218780
