NHTSA Complaint #11577864 — 2017 GMC ACADIA

Vehicle frequently shows the error "Shift to Park" when I attempt to turn off the car after it is placed in park - which is confirmable via the instrument panel. The vehicle electronics will not turn off until the error is cleared. At times I cannot clear the error and I've had to set my parking brake and leave the car electronics running while I go into a store, which leaves car unsecured and drains the battery. The car has gone into my local GMC dealer for repairs. The first time I took it in (August 2020), I was 365 miles outside my warranty and GMC refused to pay for the repairs. The dealership felt certain a recall would be issued and suggested I have harness switched which they admitted was a band-aid fix and that it wouldn't fix the issue, but it would allow a period where the error disappears (which it did) - until a recall is issued. The Shift to Park error reappeared about 1.5 years later. I took my Acadia back to the dealership and was told they could not replicate the error and therefore there was nothing they could about it. The error is happening much more often and I've scheduled another repair appointment to address the problem.
