NHTSA Complaint #11565803 — 2017 GMC ACADIA

I have a 2017 GMC Acadia with what I call a "Shift to Park" issue. This originally showed up with about 27,XXX miles on the car. It was repaired by the dealer on 9/25/2019. It worked perfectly until it started back up about six weeks or so ago with approximately 57,XXX miles on the car. I was told when it was originally fixed that they knew the issue and had an earnest fix. Not they want >$500 to fix a problem that they were supposed to fix the first time. Here is the issue. When you shift to park, and try to turn the car off, you get an error message that you need to "shift to park". I assume that the car is in park, but not sure with this warning message. You have to start it back up multiple times and play with the shifter. The other option is to let the warning keep flashing and wear the battery down. I have replied the battery on this car two times. When researching this issue on the internet, I see that there are several class action lawsuit for this issue so GM is well aware of the issue. They have apparently figured out the issue because it only affected the 2017 and 2018 Acadias from what I can tell. AS you can tell fro the mileage, this car has low annual miles and ha always been serviced by a GM dealer.
