NHTSA Complaint #11490067 — 2022 NISSAN FRONTIER

I am unsure which components, but have had more than 1 issue with this vehicle. First, was the scariest. Iwas backing out of driveway onto the roadway, and the back up alarm went of and brakes locked up as the onward traffic was coming towards me. I was barely able to move in time. There was no cars or pedestrians near the back of truck to even set it off. Still scared to back it up for fear of not being lucky enough the next time it happens. Computer system issue?? While driving, seatbelt alarm goes off 60% of time while I am wearing mine and only one in vehicle. I tried getting video of this issue since it does not happen consistently. The other issue, while driving, all the lights on dash came on and it flashed 2 different messages about the system failure. This truck is 3 months old and I am scared to drive it!! Just want to see if there have been any other people with similar experience in their Nissan.
