2004 Nissan Quest pressure valve on various tires failed/leaked. The last 4 times occurred on the left front tire while driving. No accidents. Repaired twice by resealing and twice by replacing the rim and valve. The last dates were 7/19/2005; 2/28/2006; 3/20/2006; and 12/14/2006.

We purchased a 2004 Nissan Quest with the full warranty plan. In the last several months, the passenger rear has not stayed inflated. The representative at your cathedral city office claims this is a stem valve problem but they would have to charge me $200 for the part plus $100/hr for labor and because they do not know the exact problem, we could be charged for more than 1 hour of labor. We have been told by the aforementioned service department as well as Nissan headquarters (800-Nissan-1) that this is not covered under the extended warranty plan and that Nissan will not assist in this repair. In this instance, the Nissan salesman misled us with the purchase of the extended warranty plan, claiming it covered the same as the original warranty. We are mostly displeased with this because we are being asked to fill our tire with air several times a week if we continue to drive our Nissan Quest, or spend hundreds of dollars on the valve repair because it appears Nissan doesn't want to take responsibility of not having quality parts in their tires, intentionally or unintentionally.
