Filed Mar 24, 2026 · Electrical · IA

Seeing the intermittent shift to park messages when the vehicle has been shifted into park and the ignition is turned to the off position. Shifter wire harness jumper & transmission controls A malfunctioning shifter raises fears of potential rollaway accidents, even if such cases remain rare. For anyone who has to park on a slope, this fear can cause serious worry. Yes, there is a service bulletin (19-NA-206) No, this is 1 of the only problems I have had with this. The other issues I have had is the clear coating on the rims are peeling

GMC customer care representative & local GMC service department supervisor unable to help. 2017 Acadia Shift to Park message. It’s Difficult to turn the car off. The vehicle refuses to acknowledge the park position. Potential rollaway hazard. You may inspect. Took it to GMC service & confirmed it is a prevalent issue: Transmission control 13534320 = gearshift assembly & Jumper harness 84733196. This problem has been recurring for several years and I have problem solved how to shut the car off. GMC customer care rep said it’s an issue with all 2017 Acadias and tried to help. The system deemed it complicated case & escalated it to a Supervisor. She read a “customer care” script. After talking, she admitted that realistically GMC would not help. Yesterday, she advised me to file a complaint with the federal safety agency. I read that 2 other states Ohio & Tennessee won class action lawsuits because of the hazardous shift to park issue. If GMC issued recalls for 2017 Acadia shift to park then my 2017 GMC Acadia should have been included. I have been waiting for the recall for several years. GMC admits the problem is prevalent in 2017 GMC Acadias. Would you please issue a recall associated with this issue and link it to my VIN. Thank you.

Shift to park message on the info panel and car did not go into park and began rolling away. Had to turn car back on to shift into park. On occasion, it requires multiple start/stops. This is safety issue in that if you think you're in park the vehicle can roll and potentially hurt someone because it's not actually in park. The car was stationary when the problem occurred.

With vehicle stationary, I attempted to place the transmission in "park" and turn off the vehicle. The dashboard information screen displayed the message "shift to park" and would not allow the vehicle to fully shut down (headlights remained on) even though the shift knob was in "park" as well as "p" displayed on the dashboard screen. The electronic emergency brake was inoperable and the vehicle seemed to be at risk of rolling away. This left me stranded with the vehicle and unable to remove myself from it.

When car is placed in park, the dashboard display says that the car must be shifted to park, although it is has been put in park. The car must be restarted, and reshifted to park, multiple times. (as many as a dozen times.) when the error message appears the electrical components do not shut down. The car cannot be locked. Unsure whether car is/ is not actually in park, or whether there is a danger of car rolling away.
