Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2023 Toyota RAV4 Prime?

• Check that the gas cap is tightened securely — a loose cap is a common, simple cause that can trigger the light.
• Look for obvious issues: low fluid levels, oil leaks, smoke, or unusual noises; these can indicate urgent problems.
• Note any dashboard messages or changes in performance (stumbling, loss of power) and whether the light is steady or flashing.
• If the light is flashing, avoid driving and get the vehicle to Nalley Toyota Stonecrest right away to prevent catalytic converter or engine damage.
• Document mileage and recent fuel or service changes to help our technicians diagnose quickly and accurately.
