2021 Volkswagen Atlas Cross Sport: start-stop system problems

Filed Aug 20, 2025 · Fuel system · WA

The Car has Stalled at Stoplights 3 different times. There was a message on the dashboard that told me to "manually restart the engine". I put the car in park and restarted the engine. Note: I don't use the "Eco Stop Start" mode. I'm not sure what caused this problem but in reviewing some forums it may be an N80 Valve and/or a Carbon Canister. Yes, the vehicle is available for inspection. Obviously, a stalled car could be a safety risk for the driver and others. I will be taking it to a dealer but they seemed to think it may be the battery. I don't think so, because the car started immediately once I pressed the Start Button. No Warning Signs or messages prior to Stall. Message to Manually restart after Stall.

The Atlas has stalled twice since purchase. Both times I was coming into and out of a parking spot. The second time I was almost rear ended by another car. The car asked me to start manually. Both times Auto start/stop was disabled.

Driving under 10mphs (in slow moving traffic or parking lot, etc.), the vehicle engine turns off and power steering also shuts down. I reported this issue to VW Service and they were able to reproduce the issue but are unable to find a fix for it. When the issue appeared AUTO START/STOP error flashed on the dash board. I avoided an accident this week when the vehicle turned off in rolling traffic. Vehicles behind me swerved to avoid crashing into me since my car engine and power steering turned off. The dealership said the vehicle is safe to drive which is not the case and are unable to provide me a loaner.

its been about 3 occasions , one being yesterday 2/16/24, as i was on the freeway my vehicle began to stall and it displayed , Error : stop/start, display said to manually start, got off the freeway and had to put my car into park then restart again. I almost got hit and forsure bad accidents could have happened. the other occasion was about a week ago exactly, i was on a turning lane, as i was in the middle of turning, the car stopped while in motion and it displayed the same message. I almost got hit by a vehicle. i've called my nearest dealership and they were not that helpful, they tried to force it on me that it was just the vehicle feature that come with the car. i've tried to tell them the error message but they disregarded my concern. the car has been very dangerous to drive and extremely worried and concerned

-The engine shut off while I was driving the vehicle and gave me a message to please start the engine manually by putting the car in park. This happened 6 times in 2 days including twice in traffic on the highway. The dealer said the issue was due to the evap canister being saturated and debris in the n80 valve. - This put me at risk of being in a serious accident as my car had no power. I had to put my car in park and manually restart it coming to a complete stop when Me and other drivers did not expect it. - the problem has been confirmed by the dealer - The vehicle component has not been inspected other than by the dealer to my knowledge - This happened a few times with no error message or warning sign, however after the first few times my car showed a message that would say error:start/stop at startup which I believed to refer to the auto start/stop system.

About two weeks after purchasing my brand new VW Atlas Cross Sport 2021 (purchased March of 2021) the dash board warning systems have not properly worked. The screen constantly freezes and occasionally a warning appears for vehicle collision assistance when nothing is in front of me. The tire pressure light randomly comes on but the tires are always at the proper PSI. The auto start/stop will malfunction, the car will stop running to save power automatically at a red light but occasionally it gets confused and starts/stops over and over or will not start back up at all when I put pressure on the gas pedal like it should. Yesterday, 9/6/2021, the vehicle overheated after driving it for 2 hours. The odometer was at 4,001 miles. Pulled over and opened the hood and the engine was completely out of oil and antifreeze. No check engine light or low oil pressure light ever came on. The low coolant light came on but only after the vehicle began to overheat. A mechanic who pulled over to help us stated that it was so low that it's a miracle the vehicle did not catch on fire. He stated the fluids must of come low from the dealership but that the operating syatem is supposed to warn me well ahead of time but it did not. The manual recommends 7,000 to 10,000 miles for an oil change, the vehicle just hit 4,000 miles. No warning or check engine light warning until after the emergency occurs is NOT OKAY!
