Radiator failed leaking antifreeze into transmission thus causing transmission to slip while merging into traffic.
Nissan has acknowledged that a manufacturer defect in 2005-10 Frontier, pathfinder, and xterra vehicles equipped with automatic transmissions have an internal crack on the oil cooler tube may occur leading to internal leakage of engine coolant. This defect has destroyed my transmission and many other consumers' transmissions, as evidenced by the class action lawsuits which have been filed against Nissan. Nissan offered customers an extended warranty for the radiators for vehicles with less than 100,000 miles, but never addressed the transmission issues, which range from $4000-6000 to rebuild. I realized I had an issue with the transmission while making a left turn on hwy 98 in florida, where oncoming traffic is traveling at speeds of greater than 60 miles an hour. The transmission slipped while I was making the turn and was nearly t-boned by two oncoming vehicles. It is inconceivable that Nissan has not recalled these vehicles. Nissan is putting consumers lives in danger and costing hard-working americans substantial amounts of money by not recalling these vehicles.
