In November of 2022 I noticed that after I would fill my 2018 Cadillac with fuel that it was extremely difficult to start. This same issue I had over the previous 4 years with my 2012 Buick Lacrosse twice and each time it was a GM #12690512 Vapor canister Purge Valve each time at over $300.00 to correct the problem. I could leave the car running while fueling but that is not safe to do. I believe GM has a known issue with this item and is no longer using this part in their newer vehicles.
