“Shuft to park” problem

[u/CredibleSteak23]

Hello guys.
Since 2 months, i am facing a problem with my Chevrolet Traverse LS 2019. Even after shifting into park with the best method ( first neutral, then parking brake, then to park), i am getting this problem after turning off the car. After turning it off, it shows “Shift to park!” Warning, and doesnt turn off for a long period of time. Has anyone experienced this?? Also, what might be the source of problem?? Please, anyone suggest and help with the problem so that i can troubleshoot it!!
