2013 Nissan Armada ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM

The instrument cluster starts giving wrong signals which causes the car to either shutdown or not start randomly. for now a tap on the dashboard would help it start sometimes. it is a great safety hazard as if it shuts down on a dangerous road or if it wont start in dangerous areas, which happened with me multiple times while my kids were on the car, it could cause disasters. My car stayed at the dealer for 3 weeks, they were able to reproduce the problem, but they could not resolve the issue. they contacted the engineers in Nissan and no luck. the best they were able to do was guess it was the ecm. that is after they claimed it was the fuel pump and talked me into changing it, although I had a new aftermarket pump installed a month prior, and charged me over $1200 but after a search online I came across a video of an identical issue with a person who posted a video a year ago. in his case, the engineers suggested changing the instrument cluster. the care worked since then. At the time I was watching the video I was setting in my car that wont start. I tapped on the dashboard. it worked! there will be no warning signs for the issue. no pattern either. it happens randomly. it does not shut the car down as often. but the almost daily one is not letting the car start.
