2026 Hyundai Sonata Service and Repair Manual
Two trims change names on the 2026 Sonata: the SEL and SEL Convenience give way to a single SEL Sport, and a fuel-sipping Blue Hybrid returns beneath the SEL and Limited hybrids. The N Line continues with the 2.5L turbocharged four-cylinder, while the SE and SEL Sport use the 2.5L naturally aspirated engine and the hybrids pair a 2.0L four with an electric motor. Since the trim map moved, year-exact data matters. This service and repair manual supplies the 2026 procedures, torque values, wiring diagrams, diagnostic routines and maintenance schedules for each version of the sedan.

Known issues on the 2026 Sonata. One recall is on federal record for this model year: a software error may cause the instrument panel display to fail, leaving the speedometer and warning lights unavailable, and it is corrected by an over-the-air or dealer software update. The instrument cluster diagnostics and wiring diagrams behind that fix are included in this manual.
