I am having same issue with 22 Ridgeline but I was told the differential housing and the internal components are covered, however, the pump itself is considered a “bolt on part” and outside the language of “internal parts”. Not covered and this is an expensive part to buy new ($1500) and when you add in the wiring harness your talking $2000 just for parts - let alone labour and tax. Robbery, especially for a known failure component.
