The check engine light on a 2014 Buick Encore can illuminate for various reasons. If the spark plugs need replacing, the light may turn on, but this is a straightforward and inexpensive fix, typically under $20. Another potential issue is a faulty ignition coil, leading to engine misfires or reduced power. In such cases, it's advisable to visit a mechanic or dealership for assistance. A clogged catalytic converter could also trigger the check engine light, requiring professional diagnosis and repair.
When your 2014 Buick Encore car is having issues like misfiring or a loose gas cap leading to an emissions leak, the "check engine light" will come on to alert you.
