2020 Ram 1500 electrical system problems

The contact owned a 2020 Ram 1500. The contact stated while driving at approximately 45 MPH, the windshield wiper was operating erratically, the lights began flashing, the emergency lights would not work, and the lock was inoperable. The contact observed smoke coming from the vents and underneath the dashboard. The vehicle was maneuvered to the side of the road where the contact observed sparks and flames coming from the dashboard that were approximately 5 feet in height. The Fire Department extinguished the fire.

While stopped at light when I began to accelerate making a left turn the transmission wouldn't shift out of first gear. This is dangerous should you need to quickly move car out of way. Car went up to 5000 RPM before I release the gas and proceeded to side of road. Dealer couldn't duplicate, I asked them to flash the computer and they refused, saying any updates would be over the air. Which is not true. Truck is supposed to be equipped with tailgate ajar warning light, it is in manual and on my build sheet.
