Why is the check engine light on in my Chevy Traverse?

The check engine light in your Chevy Traverse can come on for various reasons. Here are some common causes:
1. Aftermarket parts or accessories: If your vehicle has aftermarket parts or accessories that are not installed correctly, they can cause issues and trigger the check engine light. These parts can affect the battery, trigger the light, or even prevent the vehicle from starting.
2. Loose gas cap: A loose or improperly tightened gas cap can cause the check engine light to come on. If this is the case, tightening the gas cap should resolve the issue. The light will turn off on its own after a few driving cycles.
