New member. Please let me know there's an error with my post. I've found two security issues on my 2019 Silverado and wondering if I'm missing something before contacting Chevy. 1. I can start the truck as usual with keys in the vehicle, then place the keys outside the vehicle and drive away, miles away, turn off the engine and restart the truck, repeatedly. It only presents a problem when you turn the truck off AND open the door. Then, it will not restart. 2. If you find the truck unlocked and you do not have your key fob, there is no way to lock the truck. You can press the lock button but it immediately unlocks. Any help is appreciated.
