2021 Chevrolet Silverado 2500 UNKNOWN OR OTHER

Unable to remove key from ignition for a period of time ie. 30 sec. to a minute or more. After driving the vehicle for a either a long or short period of time and you park it, you can't turn the ignition lock all the way off.

Originally Chevrolet offered a 2 phase approach for this recall. First phase was to install monitoring software in the ECU and TCU to monitor for early transmission control valve premature wear. Second phase was to actually replace the suspect valve. I've just received a second correspondence from Chevrolet for this recall, now only offering Phase 1, TCU and ECU monitoring software installation. So if the monitoring software detects premature valve failure, the vehicle will be limited to 5th gear. I don't think limiting a vehicle to 5 our of 10 gears is a safe solution. If I'm on the freeway, towing 10,000 lbs, and my vehicle is limited to 5th gear, I may have to travel a very long time at way below posted speed limits before I can get to a dealer for repair. As we all know, travelling on the freeway at lower than posted speed limits can be just as dangerous as travelling above posted speed limits. And in fact, here in Idaho, if you're travelling below posted speed limits you can be fined just as if you were exceeding speed limits. I feel Chevrolet's original solution is the best. Replace the suspect valve proactively instead of actually waiting for it to fail which can possibly cause an unsafe condition.

When putting the truck back into park it will say shift to park even though it is already in park. It causes the truck not to shut off

Tailgate is opening and closing and opening and closing all on its own. This is safety hazard when towing or cargo could fall out onto the highway.
