PCV Valve froze due to poor design and crankcase couldn't vent which blew out the rear main seal. Obvious design flaw

Transmission will not go into drive or reverse. This also happens when car is in drive going down the road it will all of a sudden lose power and not go when pressing gas pedal. Vehicle has to completely shut off several times before it will go back into gear. No warning before it started. This can be dangerous when it happens in traffic and I can’t move car out of the road. It has not been inspected yet. Also blind spot warning does not always says it needs serviced.
