Buick Encore engine light intermittently on, possible gas cap issue on Buick Encore

Some Buick Encore owners report experiencing intermittent check engine lights that may be caused by gas cap issues. A common reason for the check engine light to illuminate is a loose or faulty gas cap, which can often be easily resolved by simply tightening it. If the gas cap is not properly secured or needs replacement, owners may find that the check engine light continues to turn on. While some may attempt to reset the light by disconnecting the negative battery terminal, this does not address the underlying issue, such as a gas cap problem. Therefore, checking the gas cap is recommended for those experiencing this issue, as it could potentially resolve the intermittent check engine light.
