NHTSA Complaint #11421520 — 2017 CHEVROLET VOLT

When turning the car off a "shift to park" message appeared. The car wouldn't automatically lock because it thought it was still in drive. When I returned I tried to turn the car on while still in park, I shifted back to Drive and then back to park and the same message appeared when I tried to turn it on as if it still hadn't turned off. No AC, steering or the startup sound so I tried to wiggle it and then took my foot off the brake and then turned off, I then opened the door to cut power. I put my foot on the brake and the car started normally but this is the 4th time in less than a week. Heat outside at this time of year is 115 degrees+ so being stranded for a neutral safety switch or transmission gear sensor is unacceptable especially when my Wife and daughter primarily use it. We had this problem over a year ago and they replaced the whole gear selector assembly but it is showing signs of failure again.
