2026 Acura MDX Service and Repair Manual

Following last year's refresh, the 2026 MDX is a carryover of the restyled body, 12.3-inch touchscreen and upgraded driver aids, with a new Double Apex Blue Pearl paint as the headline change. The same six trims return, from the Base through Technology, A-Spec, Advance and A-Spec Advance to the Type S Advance, with the 3.5L V6 in most models and the turbocharged 3.0L V6 in the Type S. Keeping the right year matters for software levels and parts supersessions, so this service and repair manual covers the 2026 MDX with its procedures, specifications, torque values, wiring diagrams, diagnostics and maintenance schedules.

Known issues on the 2026 MDX. One recall is on federal record: the front passenger seat weight sensor may crack and short circuit, which can cause the air bags to deploy unintentionally in a crash, and dealers replace the seat weight sensors. No owner complaints have been filed so far. This service and repair manual includes the seat and occupant classification sensor procedures, wiring diagrams and fastener torques behind that repair.
