2021 Volkswagen Atlas Cross Sport: check engine light

Filed Jul 18, 2025 · Engine, Fuel system · IL

Start stop error on 7/15/25. Engine light on 7/16/25. Drove the car to AutoZone and the diagnostic code was P0496 EVAP System High Purge Flow. VW dealership said it was okay to drive vehicle with engine on until my appointment on 7/24/25. Filled up the car with gas on 7/18/25, but the fuel gauge only went up to 7/8 of a tank and 365 miles to empty. After driving 51 miles, the fuel gauge was full and 430 miles to empty. After driving 116 miles, the fuel gauge dropped back down to 7/8 of a tank and 365 miles to empty. The car stalled today while going through the busy Burlington Road roundabout. There was a popping sound coming from the rear of the vehicle near the fuel tank after I shut it off when I got home. There was also a hissing sound coming from the fuel tank. The EVAP purge solenoid was replaced on 5/30/25, the evap system failed again on 6/19/25 at which point the vehicle was sent to VW for a software update. The engine light is on again for the same EVAP issue and now the fuel system appears to be failing because of it. I’m leaving the vehicle parked until my appointment. This vehicle is not safe to drive considering it stalls unexpectedly in stop and go traffic.

Car is stalling at slow speeds during heavy traffic, pulling into a parking spot, slowing down to cross a two lane highway, or moving slowly in a drive-through. This vehicle stalled unexpectedly on the tollway during the morning rush hour to Chicago. It also stalled at a four-way stop with limited visibility for drivers behind me on 6/18/2025. I had to call 911 because I was stalled at a busy intersection and the car would not restart. The engine light will come on and I’ll get a “start/stop” error even when I shut off that feature. The diagnostic code is related to the emissions system. I’ve had the car in the shop three times for this issue. The purge valve was changed, and the software was updated. I picked up my car two days ago after a three week stint at the dealership, and the car stalled already in the drive-thru. This vehicle isn’t safe to drive due to it stalling and sputtering unexpectedly in traffic.

While driving and coming to a stop or slowing down the cars engine will shut off. This is extremely dangerous when in traffic and you have to come to a complete stop and put it in park to manually restart the car. The dealer cannot seem to reproduce the issue but the same day I picked it up from having it looked at it died on me twice in the same day. The vehicle has not been inspected by anyone other than the dealership as far as I know as we are the second owner. There was no warning when this started happening. It gives no warning when it will or will not die. However, a week after it started the check engine light came on and that’s when I took it into the dealership. They were able to replace the sensor but did not find a reason for the car to spontaneously die.

Engine light keeps popping on due to supposedly the evaporative canister and valve are faulty. While driving my car acts as if the start/stop function is turned on (I turn it off because I don’t like it) and starts to turn off my engine while I am creeping in traffic (major traffic). This was June 2023. February 2024 same issue occurred and canister and valve needed replaced (not even a year later). A few days later the start/stop error popped up again and my car is starting to turn off while driving or creeping in traffic, with that function being turned off.

Start/stop error occurred on dashboard and a day later the check engine came on. I took it in to get diagnosed & was told the software was recalled and needed updated. A few days later the start/stop error came back on, engine light came on, car was jerking and my engine would shut off as I am driving and would tell me to start my engine manually. I was then told the evap purge valve and evap canister needed replaced. These 2 items were the first 2 line items on the diagnosis they first ran & did not check.

The car has auto on/off when idling at a stop. It will often just power down completely and not power back up when idling. Because of this at intersections i have almost been hit twice but it has happened 7 times in 1 year. The car also shows a constant seatbelt not connected symbol and loud warning when the belt is connected and nothing is in the passenger seat. This comes and goes with no prompting. The dash board will occasionally show check engine codes but nothing is wrong. One day after the car had overheated from no coolant after having just bought it a few moths prior no engine lights ever came on. The car just overheated and began to smoke and shut down on the side of the road. Today Travelers insurance was running a scan on the black box after a no fault small impact accident occurred and they used 3 forms of equipment to get a "event code" but the code would not show. The agent was perplexed and said he'd never seen this on any other vehicle but VW before. VW keeps just saying we'll do a software update but will not fix the issue.

It started with just the check engine light on but was driving fine. I alerted VW and an appointment was made for over a month out. Said it was safe to drive unless it was blinking or not acting right. After a few days, the light went off. About a week later, the check engine light came back on. Anytime I got below 2 mph it would turn on all my alerts about engine running, no lane assist, no cruise and after a complete stop it would act like the emergency parking brake was on. Sometimes when restarting the car the parking brake light was actually activated without pushing it. The driver's side windows would also randomly roll down. I immediately called the dealership and they fit me in prior to my previously scheduled appt. I was told it was the door wiring harness and it would be several months before a fix. It has been in the dealership since 04/13/2022. I do have a rental through the dealership. However, the dealership is not communicating with me even though I've left messages.

I own a 2021 Atlus Cross-Sport and the last month I have had several electrical issues with it. It first started with my driver's windows would automatically roll down, then my radio would tune in/out, my check engine light comes on and then the passenger side air bag would turn off. I then would have my parking break come on when I rolled into a stop which included consistent beeping and alarms going off. Being a concern, I brought it into Volkswagen and was told that there was a recall on a faulty wiring harness. They agreed to place me into a rental car but had none available and gave me no other choices but to continue to drive the vehicle until the back-ordered parts came in. Two days later on May 1st I was driving the Atlus down the highway when my parking break automatically turned on and my car then sieved up on me. I returned my vehicle in Volkswagen the next day because I do not feel safe in that vehicle. So now I wait, with no ETA of parts to repair my vehicle that I am still paying a note and insurance on.

Car stalled at red light before getting on the highway. As I was merging on the ramp to 295, the car started stuttering, and steering wheel was vibrating severely. EPC and Engine light popped on. Had to pull over and was almost hit by a truck. Turned on ok. A minute into the drive the EPC and Engine light popped on again and car started stuttering again. Was on major highway so had to pull off at next exit and pulled into a parking lot. Customer Care sent a tow truck, and the SUV was towed to Salem County VW in Monroeville, NJ. Called Salem County VW to let them know the SUV was in tow. Stated they would try to look at it, but to make a formal request online. Made a formal request online for an appointment at 8:45 a.m. on 9/13. Car was in shop for 10 days with a bad fuel injector.

Started with the driver door sensor not unlocking. Happened once before, errors and lights came on. Next day everything was fine. Yesterday, the driver door sensor would not unlock. All other doors unlocked, so I unlocked the driver door from the inside. Error messages started showing up such as, "Error: Start/Stop," "Attention: The engine is running," which i happened to get pictures of. The check engine light and the triangle with exclamation light came on. A door error message and brake message showed up as well. The windows will not go down. When I come to a complete stop at a red light or stop it puts the Park Brake on immediately.
