Emission Control problems of the 1999 Nissan Pathfinder

Emissions control solenoids/valve failure have plagued the vehicle for the past 4,000 miles. As testimony to precision manufacturing skill, they all fail at the same time, I. E. , not long after the federal warranty on emissions parts expires. The vacuum cut-valve bypass valve (a solenoid), the emissions canister cut-valve, and the emissions canister vent all failed at a cost of $300 in parts alone.

My "service engine soon" light came on after I filled it up with gas. Was told it was an oxygen sensor problem and then the code was cleared. Light came on again and it can't be seen at dealer for another week. A few months ago I had to get the transmission replaced and the rear and front shocks replaced and the car is only 3 years old. The company says that that happens sometimes.

Thank you for looking into this matter. While this is not life threatening, it is indee an expensive nuisance that the dealer feels I should keep paying for. My truck is not old enough to have to replace an oxygen sensor 3 times in 2 years.
