Today, with just over 19,000 miles on my 2008 Xterra, I had to replace my front brake pads and rotors. Both rotors were badly grooved especially on the inside surface and the inside pads were nearly completely worn. I had just had the vehicle inspected 2 months ago at my Nissan dealership and they reported no problems. It makes me wonder how my inspection was really done and also the quality of the parts that Nissan is using in it cars, as I have owned several cars and have never had to replace break pads much less rotors under 20,000 miles. I also experienced the difficulties with the tire pressure sensors. Two of them had to be replaced due to leaking air. I also had readings of low pressure when the tires had just been inflated to the proper setting and the light refused to turn off. After several days I took it to the dealership and they said my tires were just under inflated. I did not believe their explanation.

The 4 tire pressure monitoring system valves (TPMS) failed on the same day according to the dealer. The dealer stated the failure of the TPMS valves is a known problem with 2008 Nissan Xterras. The failure of the TPMS valve poses a significant safety issue either by misleading someone to believe a tire is going flat or by not alerting the driver a tire is going flat.
