NHTSA Complaint #11534382 — 2019 HONDA CR-V

I bought a Honda CR-V 2019 with 30,695 miles on 7/22/2022 from an authorized dealer. Vehicle had 1 previous owner and a clean record. At around 50,000 miles the car started to have some computer glitches. Interior lights and radio turning on and off. Interior screen changing randomly and rapidly between functions. Nothing to where I was too concerned. I would turn the car on and off and it would fix itself. I am now at 56,000 miles and on 7/23/23 and my car had every light on the dashboard light up. It had the engine light, brake system, traction, steering ACC and was showing warnings for: Adaptive cruise control, Automatic Emergency Braking, Blind spot warning, Forward collision warning, Lane departures warning, Lane keeping assistance, Parking collision warning, Rear cross traffic warning. I just received a call from the Honda Mechanic, and they informed me it was the fuel injectors and possible spark plugs. It will cost $1,730.00. They are also going to do a computer update and reset. Why is this problem not under warranty? This car is not that old and I make sure all my maintenance is done.
