2025 Honda Ridgeline Service and Repair Manual

Standard all-wheel drive and a 280-hp 3.5L SOHC V6 remain at the heart of the 2025 Ridgeline, which pairs that engine with a nine-speed automatic in every one of its four trims: Sport, RTL, TrailSport and Black Edition. The unibody pickup's in-bed trunk, dual-action tailgate and torque-vectoring AWD each bring service details a generic truck reference will not cover. This factory service and repair manual is built for the 2025 crew cab, with its specifications, torque values, wiring diagrams, maintenance schedules and diagnostic procedures matched to this model year.

Known issues on the 2025 Ridgeline. Two recalls are on federal record: the rearview camera tailgate wire harness can fatigue and break, leaving the camera display blank, and the front passenger seat weight sensor may crack and short circuit, which can affect air bag deployment in a crash. Owners have filed 89 complaints with NHTSA, citing exterior lighting, the electrical system and the engine among other areas. For tailgate harness replacement and occupant sensor diagnosis, this manual gives the factory wiring diagrams and procedures.
