Frequently Asked Questions About Engine Diagnostics

How long does an initial engine evaluation take? Initial scans typically take about an hour. If further testing is needed to pinpoint the exact issue, additional time may be required depending on the situation.
Should I continue driving if the check engine light is flashing? A flashing light usually indicates a more serious issue. It is safest to stop driving and have the vehicle inspected as soon as possible to avoid further damage.
Do you offer loaner cars if my engine requires extended testing? Loaner vehicles may be available for longer diagnostic or repair situations. It is a good idea to request one when scheduling your appointment.
Can I wait at the dealership during the diagnostic process? You are welcome to stay during the initial evaluation. For more complex issues that require extended testing, dropping the vehicle off may be more convenient.
