Frequently Asked Questions

What is the most common reason for check engine light on a 2022 Lexus RC F?

• Frequent causes include misfires (ignition or fuel system), oxygen sensor failures, and EVAP leaks—each can trigger a fault code and reduce performance.
• Ignoring these issues can worsen fuel economy and damage catalytic converters, creating higher repair bills down the road.
• Our dealership often costs less than independent shops over time because we diagnose correctly the first time, use factory parts, and prevent repeat repairs.
• Warranty-covered repairs must be performed at a certified dealership to preserve coverage and ensure genuine parts and trained technicians handle the repair.

What does it mean when the check engine light comes on in a 2022 Lexus RC F?

• An illuminated check engine light indicates the vehicle’s onboard diagnostics detected a problem with emissions, engine performance, or related systems.
• It can range from a loose gas cap to an engine misfire or sensor failure; each issue produces an OBD-II code that guides repair.
• At Nalley Lexus Smyrna, our inspections use factory-grade scanners to read codes and provide a clear estimate before any work begins.
• Performing covered repairs at a certified dealership preserves warranty benefits and often results in lower immediate and long-term ownership costs.

How long does a check engine light service take?

• Identification with a diagnostic scan typically takes 30–60 minutes; repairs depend on the issue and can range from a quick fix to multi-hour jobs.
• Simple repairs like replacing a gas cap or resetting a sensor may be completed same day; more extensive repairs (e.g., catalytic converter or engine work) require scheduling.
• We prioritize efficient scheduling and transparent timelines, and our factory-trained technicians use OEM parts to reduce the risk of follow-up visits.
• For warranty-covered work, repairs must be performed at a certified dealership—this protects your coverage and can save on future costs.

What is the first thing to check when the check engine light comes on?

• Check the gas cap—an improperly sealed cap is a common, inexpensive cause that can trigger an EVAP code.
• If the cap is secure and the light remains, schedule a diagnostic so our technicians can read codes and test related systems properly.
• Attempting DIY fixes without proper tools can mask symptoms and lead to larger repairs; dealership diagnostics ensure an accurate, lasting solution.
• Remember: warranty-covered repairs must be done at a certified dealership to maintain coverage and provide long-term savings through genuine parts and trained service staff.
