 I am concerned and Nissan should be too. This is a serious safety issue. This issue has happened three times since I purchased this truck less than 3 weeks ago. In the middle of driving I suddenly lose power as if I let off the gas pedal, only I don't. It just starts coasting and wont respond to me pushing down on the accelerator. All the electrical power stays intact. The RPMs stay around 1 no matter how far down I push the gas pedal. The most serious incident occurred a day ago. I pulled out from a stop sign. As I turned right I accelerated to 10 mph then nothing. No response to me pushing the gas pedal.  I floored it, nothing. I eased into it, nothing. It slowed to 5 mph and crept until I could pull off on a side street.  I put it in park and back in drive and it seemed to do the trick. If I had been crossing traffic I would have stalled and been hit by an oncoming car. The first time this incident happened I was cruising along at 40 mph when it just died on me. It slowed to 15 mph as I pushed to accelerator. It happened over 3-5 seconds. All of a sudden it came back to life and leaped up in RPMs. I emailed Nissan a week ago when it first happened. No response. I emailed them this time. No response. I called them and they have instructed I take it in to a dealer, which I will. It is 2016 certified pre-owned. Its a nice truck but of course not worth risking someone's life/health. Needless to say I'm a regretful owner.
