Check Engine Light Flashing

A flashing check engine light on a 2016 Toyota RAV4 signals a severe misfire or condition that can cause catalytic converter damage and immediate performance loss. When the light flashes, the engine control module detects that combustion isn’t occurring correctly in one or more cylinders, which can rapidly overheat the catalytic converter and lead to costly repairs if ignored. At Stevinson Toyota East in Colorado we treat a flashing light as an urgent priority: our technicians perform a complete inspection using OEM diagnostic equipment to identify ignition, fuel, or sensor failures. We explain the condition in plain language, present options that prioritize safety and long-term value, and recommend OEM parts and factory procedures to restore proper operation. We often provide same-day repair windows for critical issues and clearly list any available discounts through our service specials. If the repair is covered under warranty, we handle the claim and complete the work at our certified facility to preserve coverage. Don’t wait — a flashing light can escalate costs quickly. To protect your vehicle and avoid downstream damage, schedule service with our team immediately; our service financing options make urgent repairs affordable so you can drive safe today and pay over time.
