Owner complaint summary

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.

This is an owner complaint filed with NHTSA (ODI #11548946). It is not automatically an official recall, investigation outcome, or manufacturer admission unless the complaint text itself describes one.
