 This is my second Pathfinder. They are nice looking vehicles and fun to drive. Poor mileage. My son has my 97 and still running great with 157K and using no oil.  I now have 123K on my 2001 and is running well except for ongoing check engine light problems that no one seems to be able to fix. The check engine light has been on continuously for 4 years now.  I've had O2 sensors, mass air flow sensors, cat converters, coils, etc.. This is frustrating!  With all the problems of this kind listed in these reviews, why has this not been a recall?
