I bought my Passport under the Certified Vehicle Program when it was 2 yrs old. I'm glad I did, because the warranty covered 2 of my 3 intake gasket replacements, plus a bunch of other continuous problems. The dealer told me the gasket problem was a defect in the production of this vehicle by ISUZU, and that they had a lot of Passports come through with the same problem. I loved the exterior look, the interior styling was sharp, and it had plenty of room. Too bad I couldn't go a year without taking it in for some sort of repair. I just sold it at 133,000 miles, and it now needs a EGR valve replacement.
Great at towing, lots of interior room, classy outer and interior.
Since it's already 9 years old, this won't matter much. Better Intake gasket design would be my number one priority.
