NHTSA Complaint #11593082 — 2021 VOLKSWAGEN ATLAS

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. I have also noticed when i park my car and my gas is close to the empty line it shoots back up just a bit next time i turn on my vehicle. Now I am monitoring my gas gauge as this may be faulty and what caused all the safety issues I was experiencing. I drive my car very scared these days not knowing when it will randomly turn off on me while driving.
