2016 Chevrolet Equinox electrical system problems

My 2016 Chevrolet Equinox caught on fire about 10 minutes after my accident. I rear ended a pickup truck going about 5-10 miles an hour. Although nobody was hurt, I don't think SUVs should catch on fire. I'm unaware if this problem is frequent in 2016 Chevrolet Equinox, but there wasn't any warning of the sudden fire that appeared from the engine, i.e. sirens, sounds from within the car. I'm unaware if Chevrolet, law enforcement or the insurance company has inspected the vehicle after the accident?

Initially the rear main seal was leaking or broken; all the oil drained from the vehicle. After spending $992.60 I was advised that the timing change and guides needed to be replaced. I've had the vvt celanide replaced as well as the crank and cam shaft sensors; the vvt gears and an oil pump rebuild...$2017.60 later, my truck drove for approximately 3 miles where it died on the side of the road. I have not driven my car (aside from the 3 miles) in nearly 2 months.
