Vehicle would not go into park fortunately we were in a safe location to avoid a possible accident or injury. The vehicle has electronic transmission shifting. According to the dealership the park solenoid in the transmission valve body failed. This prevented us from putting the vehicle in park so it could safely be shut off. We were able to set electronic parking brake but ignition continued to remain on. Eventually had to disconnect the negative battery terminal. Had vehicle towed to dealership but could not release electric park bake or start vehicle with battery terminal reconnected. This is becoming a common problem with this transmission, so common that parts are on back order. This could be a very unsafe problem with this vehicle in the right circumstance. There should be a recall on this transmit that is used on multiple GM vehicles

After filling up fuel, vehicle runs rough, hesitates, and stalls at idle speeds. This occurs after every fill up. The check engine light comes on and states an issue with the anti-lock brake system. I-??ve had the vehicle checked by Buick 5 times and they have not been able to replicate the issue, so troubleshooting stopped. I know a recall came out this July for 2019 Buick Enclaves to replace the evaporative emissions purge valve due to not fully closing. This is the issue with my 2020 Buick Enclave and is a massive safety concern as the vehicle stalls while driving at slow speeds after fill up. Most recent event occurred on October 5th. I-??ve posted a picture from last year that captured the same issue.
