Total transmission and radiator failure. a dealership "fixed" the coolant contamination problem when nissan offered the warrantied coverage for what's known as SMOD. all the dealership did was flush the transmission and radiator. they did not repair or replace any components even after being berated by my husband to do so and to do it under the covered warranty.($5k for tranny replacement that we couldn't afford) they claimed the flush had fixed the xterra. less than 3,000 miles later I was driving on the highway with my 2 children in the car and the vehicle just shut off. no warning lights or behaviors just shut off at 70+mph on the highway. while sitting broke down [pulled off highway edge as far as I could after vehicle died and before it coasted to a complete stop] we were then rear-ended and my 2 kids spent 2 days being monitored in a children's hospital. 1 of which had a concussion. although the xterra only needed a new rear hatch and bumper and etc insurance didn't consider it totalled so it was cosmetically repaired. after reaching out to nissan about the incident they refused to even offer us any sort of discounted repair costs on tranny replacement[car was still under extended coverage warranty] nor would they offer any kind of anything regarding a discount on a replacement vehicle. so here we were still paying on a car loan for a car that was still under warranty, but could not be drove. or even starred for that matter. it ended up wrecking us financially. the car
