Frequently Asked Questions

What does it mean when the check engine light comes on in a 2017 Toyota Prius Prime?

• It signals that the vehicle’s onboard diagnostics detected a fault—anything from a loose gas cap to a misfire or emissions control failure.
• Common causes include oxygen sensor issues, catalytic converter efficiency faults, evaporative emissions leaks, and ignition misfires.
• Ignoring the light can increase emissions, reduce fuel economy, and cause larger repairs later; immediate diagnostics help avoid long-term costs.
• Our dealership often costs less than independent shops while offering factory-trained technicians, OEM parts, and warranty protection for covered repairs.

How long does a check engine light service take?

• Basic diagnostic scans typically take 30–60 minutes to read codes, inspect related systems, and estimate repairs.
• Simple fixes—like replacing an O2 sensor or tightening a loose cap—can be completed the same day; complex repairs may require additional time for parts and testing.
• We prioritize clear timelines and immediate estimates so you understand immediate and long-term savings from proper service at our certified dealership.
• Warranty-covered repairs must be performed at a certified dealership to preserve coverage and ensure long-term protection.
