The shift to park in my 2018 GMC Acadia was faulty. On many occasions and randomly, the car would be in park but would not turn off, saying I needed to shift it to park in order to turn the car off. This has left me unable to turn my car off resulting in dead batteries and missed appointments and being late for work. This defect is well documented by GM in TSBs PIT5616A, 18-NA-297, and 19-NA-206, which describes the exact symptoms and repair that I had to have completed. This problem has been on going and as a teacher I cannot continue to be late for school because my car, though in park, would not turn off. Given GM’s prior acknowledgement of this defect, I believe reimbursement is warranted. I have never been notified of a recall on this.
