Absolutely loved my Xterra, kept it maintained and planned to keep it a very long time. Then the problems started after I hit 60,000 miles. Fuel sensor, several batteries, belts (that had screeched since 1 year old and dealer couldn't figure out), then the tensioners, timing chain. After that $1,000+ repair, saw online all the radiator leaks into the transmission being reported and decided to cut my losses and traded it in. Received notification of an extended warranty on the radiator/tranny failure to 80,000 miles the week after I traded it. Had 70,000 on it anyway and would not have been willing to take a chance on needing that $5,000 repair. Depressing.
4 wheel drive. Powerful engine until break downs. Easy to clean inside. Great for dogs.
