- Evaluating Reliability: Frequent check engine light activations may suggest underlying reliability issues that could affect your ownership experience.

- Request Maintenance Records: Ask the seller for maintenance records to see any repairs related to the check engine light.
- Perform an OBD-II Scan: Use an OBD-II scanner to check for any current or past trouble codes that could indicate issues.
