My 2019 Blazer won't shut off the electrical system because of a "shift to park" error. This causes a drain to the battery and could leave me stranded. The problem is simple electrical switch that is not making the connection to tell the car to shut off. This is a well documented problem with chevy vehicles in the late 2010s and includes multiple models. I have not had the problem verified by a Chevrolet dealer. I've reviewed multipe youtube videos that has had 10s of thousands of views which demonstrates the problem is very wide spread. Why is this not being recalled?

When I am shifting my vehicle to park (gear shift in console area) and turn my vehicle off I will get an error code in my dashboard that I need to shift to park. My gear shift in the console is lite up P and my dashboard electronic system says P; but when I try to turn my car off it won't turn off and stays on again giving me the error code that need to shift to park. I then have to turn my car back on to then try and turn it off with the same error code coming on. I can try pushing the gear shift further with no success, shift to different gears back to park, and try waiting a few minutes after shifting to park before turning it off and still no success. This is a safety issue that my car is not really in park and will take off if I take my foot off the brake when this is all occurring. I at one point had to turn my vehicle on and back off with no success at least 5 times before I can finally get it to turn off. This problem has been confirmed by multiple Chevrolet dealerships with all of them saying they have seen many vehicles (same make and model with other models included) with this issue. Manufacturer knows about it.

When I stop and put my vehicle in park the panel lights up and says put car in park and it is in park. I am not able to shut off my car when this does that. There have been recalls on the 2019 blazers for this specific reason. Mine did not make the cut. I had to pay $400.00 to get this fixed from the Chevrolet dealership and it's the same thing that has been happening for the other 2019 Blazers that had recalls. I would like to be reimbursed. Thank you

Receiving shift to park error when attempting to shut off my vehicle. In December 2021 I had the parts replaced at the dealership, and as of a week ago the issue has started back. I am concerned that I will be stucked somewhere unable to shut off my vehicle or worst-case it doesn't actually stay in park.

This is a safety issue in that the shifter wire harness malfunctions and will not let the electrical system to confirm that the car is in park and won’t let it cut off. I have had this repaired once, and it is now beginning to show the same thing. 1) you can’t cut the car off. 2). Letting it run until the automatic cut-off kicks in can run the battery down. 3)you can shut it off in neutral, but the key alarm sounds the entire time and if the parking brake does not hold, it can roll. Leaving a car unlocked can lead to theft, but it also can lead to someone getting into your car for other reasons.
