Airbag light illuminated on this vehicle yesterday, however, it's not currently listed in campaign 21V892, but I believe it could also possibly be affected by the airbag control module issue. This vehicle also shuts down when stopped, and at times will not automatically restart when the drivers foot is removed from the brake. This has almost caused driver to be rear-ended multiple times, when the traffic signal turns green, yet the vehicle engine will not restart. The only way to restart is to press the brake again, put transmission/gear shifter into park, and restart vehicle, then put vehicle back into Drive. This is not only a hassle, but is dangerous, as other drivers expect that when the light turns green, this vehicle should then be driven forward, but at times, the engine failing to restart causes an unsafe driving condition. …
My 2021 VW Atlas SE died at a drive thru again. And when I took my foot off the break, it didn't start back up. I completely panicked. At start up initially I disable the start/stop as usual. At this stop sign, my engine completely shut off, dash said to manually start. I tried to pull off but my car just jolted as if I had the park break on. I hit the start button but nothing. I had to put it in park then start again. But I had to wait for traffic to pass and it killed again on me. I put it in park again, start button then was able to pull away. This happens randomly every few weeks with no warning. Pulling into a car wash, bank atm, drive thru, etc... I've taken it to multiple VW dealers who tell me that if they can't get it to recreate the issue, there's nothing they can do. But it's random and unpredictable. …
My vehicle has been to the dealership multiple times for incorrectly stalling, revving RPMS at uphill turns and rough idling with no corrective action taken. initial issues started around 30k miles and the dealership continued to tell me nothing is wrong because engine light was not on. I recently went over a speed bump in a school zone. My vehicle stalled and my engine light came on. Initial code was P0446 error code indicates an evaporative emission control system (EVAP) vent control circuit malfunction. The N80 purge valve and charcoal canister were to blame for this uneasy safety issue. I was told at the dealership that my charcoal canister might malfunction if i overfill my vehicle with gas which made me realize, this may have been the initial issue. I put gas until it clicks off but i have noticed my vehicle went from filling up with 16.5 gallons to stopping at 18-19 gallons. …
My 2021 Atlas with around 28,000 miles turned off on me instead of restarting while the auto start/stop function was engaged. This happened 3 times. 1) June 26, 2024 I was in standstill traffic. My auto start/stop was engaged and when I took my foot off my brake to move, my Atlas engine turned off (power stayed on) and a message appeared stating "please start engine manually". I had to switch my car from Drive to Park and then turn it on again. 2) June 26, 2024 I was parking and when maneuvering in to a parking spot and took my foot of the break, my Atlas engine turned off (power stayed on) and a message appeared stating "please start engine manually". I had to switch my car from Drive to Park and then turn it on again. 3) July 8, 2024 same as number 2. Except I know for a fact that my start/stop was turned off. …
Engine shut down 4 times in one day. I'd have to put it in park, in the middle of the road, and restart the engine. It seemed to happen at very low speeds. engine light came on. Took it to a local mechanic who noted the error had to do with a sensor in the grill that allows airflow into the radiator - the sensor was blocked based on the code, but it was not. The thought was perhaps something had been blocking the sensor but whatever was blocking the sensor had naturally fallen off since the mechanic found nothing actually blocking the sensor. Drove around for a few days, no issues. Heading out on vacation - about 4 hours into the drive on the highway, it stalled again, again at lower speeds in traffic. Turned around to go home (no vacation), stalled again 3 more times, all in heavy traffic. It is now at a VW dealership. …
