Tail Light Switch problem #1

I have been warned by other drivers at night that my tail lights were out. My clock and radio both are malfunctioning. I just took the car for the yearly inspection and there is a major oil leak from a gasket. The car only has 16,000 miles on it!.

Exterior Lighting problem #2

My car is experiencing extreme ghost screen. Also when this happens I get a lot of warning lights when nothing is truly experiencing fault. My screen will jump, change settings, reset settings,become dark on it own, not turn on at all, flip through the system causing major distractions. For instance I was driving in my car with quiet no noise then my screen jump and without warning blasted am and scared the living heck out of me while on the highway. It has called people and hung up on its own. Lights flicker and one side of my top lights don't work. My plugin have no electricity coming to them. There are times I have trouble connecting to bluetooth.

Headlights problem #3

Purchased brand new 2020 Mazda Cx-5 on sept 25, 2020. On sept. 29, 2020 with < 500mi: while traveling approximately 45 mph on county road, pressed brake pedal and the pedal did not move. Several malfunction lights flashed including "power steering malfunction", "Smart city brake support malfunction". Repeatedly slammed on the brake pedal and it did not move at all. Tried to swerve to avoid a vehicle but the steering was unresponsive. Impacted a vehicle at a red light. Mazda service said that there was no indication that the brake was engaged before the impact except for a "hard brake event" which based on the cdr data was probably the impact avoidance system braking the vehicle. As an engineer familiar with this type of system but not this particular system specifically, I suspected a low voltage event that knocked out the brake booster and power steering. Vehicle was returned from the repair shop today oct 28, 2020. Headlights began to flicker, again an indication of low voltage or faulty wiring. I have taken video of the flickering, I have obtained the cdr report Mazda refused to provide although I requested to see it, and the service report indicating mass airflow & vacuum codes, both caused by low voltage event.
