2021 Chevrolet Trailblazer

My vehicle displayed a Shift to Park message even though I was already in Park. I could not turn off the engine, I could not lock my car. I had to go back into Drive and then Park mode and wiggle the shifter multiple times to get it to recognize Park and turn off the car. This is now happening almost every time I drive the car. I did an internet search to see how to rectify the problem only to find that this exact issue has plagued GM vehicles for a decade and they still have not chosen to rectify the faulty part. There have been multiple recalls and class action lawsuits for the SHIFT TO PARK fault but not for my vehicle year YET! There are many Trailblazer owners who are experiencing this exact issue (on online forums) and GM so far is refusing to take responsibility and issue a recall to fix the issue for owners and also to stop using this faulty system in their cars. I have reached out to GM about this multiple times the past few weeks and requested they pay for diagnostic and fix the problem because it is a common and known problem with GM vehicles but they want me to pay for it myself and the repair and then they may decide to help out - unacceptable in my opinion. To be honest there needs to be a recall NOW and GM needs to be forced to change the components in all new models to stop this happening in future models going forward. This problem can cause the car battery to drain, it can cause the vehicle to roll away if it’s not recognizing it’s in Park. Thankfully that hasn’t happened to me but others have had this happen. Not being able to shut the engine off or lock my car is a problem. This is a safety issue that needs addressing. I have lots of messages and communication from General Motors which I have attempted to attach the screenshots with the photo below but get an error message on the upload page.

I am unsure which component maybe failing, Vehicle has not been in altered in any way ,inspected yet, nor has any warning indicators. This 2021 Chevrolet Trailblazer uses a traditional key for ignition. On several occasions now, the key is becoming lodged/stuck in the ignition when attempting to shut down or turn off the engine and remove the key. Have made sure foot is on the brake, front steering tires are straight, Shifter is properly engaged in the park position, and even jiggled the key tumbler assembly. Have had to leave the stuck key in the ignition while grocery shopping, until returning home to ask my fiance for his help and assistance. When this problem happens it is not only an inconvenience, but leaving a key in the ignition to an unattended car, obviously is not good, and leaves opportunity for many not good possibilites to occur.

At 44 K miles, my car started giving me a message "Shift in to park" after I stopped my car and turned off the motor. I was unable to essentially shut my engine off and leave my vehicle. I called the GMC shop, where they diagnosed it as faulty wiring. It is not under warranty, therefore I will encure the cost which is not a normal item to go out on a vehicle. Also, our 22 Trailblazer is also giving us this same message.
