Hello all. I have had an issue with my 2014 maxima SV that has happened twice while at a full stop with the car in drive. The first time I was stopped at the light and noticed the RPM fluctuating right before the engine fully shut off and all the dash lights turned on and the power steering turned off. I immediately put the car in park and then back in drive and got home fine by inching forward at stops and lights (to keep the RPM up as that was my guess). The second time was pretty much an identical situation where I was stopped in drive. I took the car to get diagnosed at a dealership and they couldn't find anything wrong with the hard code or duplicate my issue. I am now planning on just driving the car until the issue arises again, but I'm concerned that it wont just go away. There are currently no warning lights on and the oil had been changed prior to these events.

If anyone has experienced a similar issue or has any idea what the problem might be, you would be of more use than the crappy dealership I just took it to. Thanks in advance!
