First problem sounds like a sticking heater control valve, or possibly a electrical issue like a relay.
Second problem sounds like like your neutral safety switch or misalignment of shifter mechanism.
It's under warranty, take it in and have it fixed.

There's no heater control valve in these trucks and the no start problem is much more likely to be a WIN module failure than a transmission range sensor.

So what is used to activate the heater? Is water always running through it? I am just wondering.

If no heater control valve then pretty sure it uses a door to control amount of air passing thru heater core.

Yes, water is always flowing through the heater core and the system uses electronic doors to regulate temperature, mode and and recirculation doors.

Sure does its a Heater Blend Door Actuator. I guess it will be real easy to find a leaky heater core in these trucks
