The evidence of engine and power transfer evidently progressed over of days and regressed within a matter of hours, then minutes to the point where engine would barely start and obviously barely propel the truck over 10 mph w/engine dying out regardless of throttle or automatic shift position. I limped the vehicle to the nearest respected and qualified tech bob wells -total car care. This is the second time Nissan's lack of "due diligence" left customer down, all within a year or so. A frustrating,time consuming,and costly experience.
