The 2026 Lexus ES brings advanced onboard diagnostics that store specific trouble codes when something deviates from normal operation. In Frederick, CO, Stevinson Lexus of Frederick is equipped to read those codes immediately and provide an accurate plan for repair. Common codes for the 2026 Lexus ES include oxygen sensor or O2 faults, which if ignored can reduce fuel economy and damage the catalytic converter; EVAP system codes, often caused by a loose gas cap or failed purge valve; misfire codes that could signal ignition or fuel delivery issues; and battery/charging codes that indicate the need for battery replacement or alternator service.
