NHTSA Complaint #11489147 — 2017 GMC ACADIA

I own a 2017 Acadia Denali (purchased 10-4-17) We started having trouble with the vehicle in that a message appeared saying to shift the car into park. It would shut off but the lights and radio would stay on and you couldn't lock the vehicle. I took it to Ferman GMC in Wesley Chapel on May 28th of 2019. Supposedly they could not replicate the issue. The problem continued and we took it in again on May 31st of 2022. Again, they couldn't replicate what we were encountering. Now it's getting worse, happens almost every time we use the vehicle. So back to Ferman yet again (Oct 12th 2022). Now they are aware of said problem (code is b000a park switch circuit open). At this time they installed an SL-N-SWITCH and N-HARNESS at a cost of $63.13. Then labor, shop fees and taxes brought the total to $760.91, out of my pocket for a known problem. We have also come across a class action suit identifying this as a problem. And a TSB is also out there titled 'Vehicle displays shift to park message on DIC when in park. Vehicle may not shut off when put in park or may not start". There is a NHTSA ID number for this issue: 11353147
