It’s typically a yellow or orange light that looks like an engine with an exclamation point or the words “check engine” written underneath. When the light comes on, it’s important to take it seriously and get the problem diagnosed as soon as possible.

There are many potential causes for the check engine light to come on in your Buick. Some of the most common include:

If the check engine light comes on in your Buick, it’s important to take it seriously and address the problem as soon as possible. Here are some steps you can take:
