The check engine light flashing in a 2017 Chevrolet Impala indicates a serious condition — often an active misfire that can damage the catalytic converter and other engine components. When you see a flashing light, immediate action is important: reduce speed, avoid heavy loads, and arrange for inspection as soon as possible. At Larry H. Miller Casa Chevrolet in Albuquerque our technicians use factory-grade scanners and live-data tools to find root causes quickly.

Check our current service specials for savings, and remember that service financing is available so you can address urgent repairs without delay. To protect your vehicle and avoid costly damage, schedule service online now or contact our service team for immediate guidance.

2017 Chevrolet Impala Check Engine Light Reset

Resetting the check engine light on a 2017 Chevrolet Impala without resolving the underlying fault can mask problems and lead to more extensive damage. Our dealership recommends a dealer-performed reset after diagnostics and any necessary repairs are completed. At Larry H. Miller Casa Chevrolet in Albuquerque, resets are done alongside a full diagnostic report, OEM repairs, and warranty documentation so the issue won’t return unexpectedly. By choosing dealership service you benefit from certified technicians, genuine Chevrolet parts, and a documented service history that supports resale value.

2017 Chevrolet Impala Check Engine Light Codes

Common check engine light codes for a 2017 Chevrolet Impala include P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), P0171/P0174 (fuel trim or vacuum issues), and P0135 (oxygen sensor heater circuit). Left unaddressed, these can cause higher emissions, poor fuel economy, decreased performance, and expensive component failures. For example, ignoring a P0420 can lead to catalytic converter replacement costs far above the diagnostic fee. At Larry H. Miller Casa Chevrolet in Albuquerque we provide clear cost comparisons: a timely oxygen sensor replacement or targeted repair often prevents the much larger expense of downstream items. Our service center prides itself on quick turnarounds, factory-trained technicians, and transparent estimates that demonstrate immediate and long-term savings.
