2023 Volkswagen Atlas fuel system problems

At approximately 8500 miles the car started randomly stalling, maybe once or twice a week. Now at 9600 miles it stalls every time we drive the car. This is not the Start/Stop system as we deactivate that when we get in the car. Typically, the car is warm, the AC is on, we have idled with the car in park then place the car in gear to drive and it dies. The dealer claims they cannot duplicate the problem. Also, the throttle is very non-linear.

The contact owns a 2023 Volkswagen Atlas. The contact stated that on the first day the vehicle was purchased, while driving at an undisclosed speed, the vehicle failed to accelerate as intended while depressing the accelerator pedal. No warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the carbon canister and evaporative (EVAP) canister had failed. The vehicle was repaired. The contact stated that the failure persisted. The vehicle was taken back to the dealer.
