2026 Nissan Murano Check Engine Light Reset

The check engine light reset on a 2026 Nissan Murano should only be done after diagnostics confirm the root cause. Clearing codes without repairs can hide progressive damage, mask emissions issues, and risk voiding warranties. At Larry H. Miller Nissan Mesa in Mesa, AZ, our process begins with a full OEM-level scan that identifies stored and pending codes, freeze-frame data, and pending misfires. We discuss transparent options—repair now, monitor, or reset—so you understand immediate costs and long-term savings. Using OEM parts and factory procedures ensures durability and keeps your warranty intact; remember, warranty-covered repairs must be completed at a certified dealership to remain valid. If you prefer to finance the work, we offer service financing so you can get necessary repairs now and pay over time. Before any reset, ask about our current service specials and schedule service online—our certified technicians will walk you through the findings and recommended service steps to protect fuel economy and resale value.

2026 Nissan Murano Check Engine Light Codes

Common codes seen on a 2026 Nissan Murano at our Mesa service center include P0300 (random/multiple misfires), P0420 (catalytic converter efficiency), P0171/P0174 (lean fuel trim), P0128 (coolant thermostat), and P0442 (EVAP small leak). Each code carries different risk and cost profiles: untreated misfires can damage catalytic converters and lead to a $1,000+ replacement; unresolved oxygen sensor issues degrade fuel economy and emissions; EVAP leaks often start as inexpensive repairs but can lead to failed inspections if ignored. At Larry H. Miller Nissan Mesa, we prioritize fast, accurate diagnostics with factory tools to avoid unnecessary parts replacement and to reduce long-term costs. Our certified Nissan technicians provide upfront estimates, use OEM parts, and apply proven repair sequences to restore performance and maximize vehicle longevity. We often cost less than independent shops thanks to efficient diagnostics and targeted repairs, and service financing is available to ease immediate expenses.

Check Engine Light Flashing

A flashing check engine light on a 2026 Nissan Murano signals an active misfire or condition that can quickly damage the catalytic converter and other components. This is an urgent condition: continuing to drive may cause severe engine or emissions system damage and substantially higher repair costs. At Larry H. Miller Nissan Mesa we treat flashing lights as priority cases and will perform a prompt diagnostic to identify misfires, ignition or fuel delivery failures, and potential sensor faults. We recommend stopping driving and arranging a service visit; our team can advise towing to the dealership if needed. Take advantage of our transparent pricing, OEM parts, and certified technicians to minimize downtime and protect long-term value.
