Check Engine Light Flashing

When the check engine light on a 2024 Toyota Highlander Hybrid is flashing, it signals a potentially severe problem that requires immediate attention. A flashing light often indicates a misfire, which can damage the catalytic converter and lead to expensive repairs if ignored. Hybrid-specific systems may also be affected, increasing risk to both the gasoline engine and electric drive components. At Herb Chambers Toyota of Boston our technicians are trained to triage flashing-light situations quickly: we pull codes, evaluate ignition and fuel systems, and inspect hybrid components with Toyota-approved diagnostic tools. Addressing a flashing light promptly preserves fuel economy, reduces long-term repair costs, and keeps emissions systems functioning correctly. We frequently offer targeted service specials to make urgent repairs more affordable, and our service financing helps you get the work done now and pay over time. If you see a flashing check engine light, do not drive extensively—contact us to schedule service right away and protect your Highlander Hybrid.

Resetting the check engine light on a 2024 Toyota Highlander Hybrid can be straightforward, but a simple reset without proper diagnosis risks masking underlying issues.

Our process combines precise code reading with root-cause testing so resets are followed by correct repairs using OEM parts and factory procedures. We provide clear, itemized estimates and discuss warranty coverage—reminding customers that warranty repairs must be done at a certified dealership. Choosing our dealership means transparent pricing, fast turnaround, and the confidence of Toyota-trained technicians. Take advantage of current service specials or apply for service financing to manage cost—then schedule a service appointment with us for a reliable, lasting fix rather than a temporary reset.
