2018 Honda Odyssey Service and Repair Manual

This factory service and repair manual for the 2018 Honda Odyssey is built around the exact engine and trim combination Honda sold that year, including the 3.5L V6 (J35Y7), so every torque value, wiring diagram and diagnostic step matches what left the factory rather than a generic van-family reference.

Engines covered

• 3.5L V6 — SOHC, naturally aspirated, gasoline

Body styles covered

• 4-door mini passenger van

Trims covered

• Elite
• EX
• EX-L
• LX
• Touring

Known issues on the 2018 Odyssey. Sixteen recalls are on federal record for this model year, more than most vehicles on the road. Several center on the power sliding doors, where latch assemblies and, separately, water-damaged outer handle cables can let a door open while the van is moving. The rearview camera is covered twice, once for a coaxial connector fault and once for water intrusion, both of which can blank the reverse-view display; a related instrument-panel software issue can also drop the speedometer and gear-position readout. Braking and wheel-speed items include rear brake caliper pistons with insufficient coating that reduces stopping performance, and, on wheelchair-conversion units, a mis-routed rear wheel speed sensor harness that can keep the anti-lock system from engaging correctly. A damaged parking rod tied to a rebooting Transmission Control Unit can let the van roll when parked. Powertrain and fuel recalls cover a connecting rod bearing that can seize the engine and a fuel pump that can fail and stall it, plus a Braun-modified fuel tank prone to overfilling into the charcoal canister. Restraint-system recalls address a third-row seat belt tongue that may not latch, a front seat belt buckle channel that can block the release button, and two separate air bag issues, a software error that can deploy the side curtain bags unexpectedly and a front passenger weight sensor that can crack and short. A pinched wire harness at the third-row power outlet is also on record for the possible electrical short it creates. Owners have filed 969 complaints for the year. The factory diagnostic and repair procedures behind every one of those systems are in this manual.

From a sliding door that won't latch to a rearview camera that's gone dark, this manual keeps you on Honda's own procedure and torque spec for your specific 2018 Odyssey.
