2021 Nissan Murano Check Engine Light Reset

Resetting the check engine light on a 2021 Nissan Murano can be as simple as clearing a resolved code, but an unverified reset can mask a persistent issue and lead to larger failures. At Larry H. Miller Nissan Mesa we reset codes only after a full diagnostic and necessary repairs, ensuring the root cause is fixed. Our process includes scanning for stored and pending codes, performing recommended repairs with OEM parts, verifying warranty status, and confirming the repair with a final test drive and re-scan. This transparent approach protects your vehicle’s longevity and maintains factory coverage — remember that warranty repairs must be done at a certified dealership to remain valid. We also make it easy to budget for service with financing options and highlight current service specials on repairs. For reliable service and a verified reset that won’t return, schedule appointment at Larry H. Miller Nissan Mesa and trust our factory-trained technicians to keep your Murano running at peak performance.

2021 Nissan Murano Check Engine Light Codes

Common check engine light codes for a 2021 Nissan Murano include P0420 (catalyst system efficiency), P0171/P0174 (fuel trim issues), P0300 (random/multiple cylinder misfire), and oxygen sensor or EVAP system codes. In Mesa, AZ, owners trust Larry H. Miller Nissan Mesa to interpret these codes accurately and present clear repair options. Ignoring each of these can lead to escalating costs: for example, an unresolved P0420 can require catalytic converter replacement, significantly more expensive than timely sensor or exhaust repairs. A P0300 misfire left untreated can damage the catalytic converter and engine internals, increasing both immediate and life-cycle maintenance costs. Our dealership offers rapid diagnostics, OEM parts, and factory-trained technicians who prioritize repairs that preserve fuel economy and vehicle longevity. We provide transparent estimates, highlight long-term savings, and promote available service specials. To minimize expense and downtime, schedule service with our team — we’ll diagnose codes, review warranty coverage, and recommend the most reliable, cost-effective path to keep your Murano safe and efficient.
