• The light indicates the vehicle’s onboard computer detected an issue: anything from a loose gas cap to emissions-system faults or engine misfires.
• Some issues are minor and resolvable quickly; others, like misfires or catalytic converter problems, can cause drivability or emissions failures if ignored.
• Our technicians perform a full scan and explain the code, cause, and recommended repair so you understand immediate needs and long-term implications.
• Using our dealership preserves warranty coverage and delivers certified repairs that often save you more over time compared with fragmented independent fixes.

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

• Start with simple checks: ensure the fuel cap is tightened properly—an EVAP leak from a loose cap is a common, inexpensive fix.
• If tightening the cap doesn’t help, bring the vehicle in for a professional scan; our factory-level scanners read pending and stored codes to pinpoint cause.
• Never clear the light without diagnosis—clearing codes can hide intermittent faults and negate warranty documentation; certified diagnostics protect your coverage.
• We provide clear next steps and cost estimates, emphasizing immediate savings and avoidance of costly downstream damage by addressing issues correctly the first time.

What is the most common reason for check engine light on a 2017 Toyota RAV4 Hybrid?

• Some causes are simple and low-cost to repair, while ignored sensor or misfire problems can escalate to expensive catalytic damage.
• At Nalley Toyota of Roswell, our inspections identify root causes and recommend repairs that maximize reliability and minimize long-term expense.
• Remember: warranty-covered repairs must be performed at a certified dealership to remain valid; we process warranty work efficiently and accurately.

• If repairs are required, completion time varies with part availability; we stock common sensors and parts to minimize downtime and offer timely appointments.
