Report: Check Engine Light Due to Gas Cap Issue
Buick Rendezvous Problem
Average Mileage: 103,400 mi (58,000 mi - 147,000 mi)
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
I had the service engine soon diagnosed by Autozone and they said to replace the gas cap and add fuel injector cleaner. So far it worked.
