I have brought my 2018 Buick Lacrosse to two different Buick dealerships who say that even though a special instruction letter was recognized and a recall was observed, because my check light went out and the codes on the car where cleared, they will not fix either recall.

HOWEVER, THIS IS NOT A RECALL AND I SHOULD NOT SEEK A REPAIR UNTIL I HAVE EVIDENCE THAT MY VEHICLE HAS THIS PROBLEM. THIS SOUNDS LIKE A SERIOUS SAFETY RISK TO ME.
