2024 GMC CANYON Fuelpropulsion System Problems

I've noticed an issue since I picked up my vehicle from its last service where the RPMs stay around 1,000 when I let off the gas and should be coasting. The vehicle will continue to accelerate at 11 to 13 mph, and I really have to mash the brake pedal to stop. There is an update notice that popped up starting yesterday, but it will not install. Looks like the update is for the issue I am having. The update was supposed to be installed already per the service bulletin. Update number is N242452130

Rack and Pinion assembly failure. Steering became “sticky”. Had to pull on the wheel to break it loose multiple times to make a full turn. This occurred while driving on the highway. No warning or lights. Confirmed by dealership. Truck has 2200 miles, under warranty. When I took the truck in they also informed me there was a recall on the fuel injection computer. I found that strange considering I was never alerted of this recall nor can I find it anywhere online with my vin number.
