2017 GMC Acadia

The contact owns a 2017 GMC Acadia. The contact stated that after the vehicle was parked and the gear shifter was shifted to park(P), the vehicle failed to turn off as intended. The message "Shift to Park" was displayed on the instrument panel. The contact stated that the vehicle was parked, and the gear shifter was shifted to park(P), however the vehicle failed to recognize that the gear shifter was in park(P). The contact jiggled the gear shifter button several times and was able to turn off the vehicle. The failure was intermittent. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired, and the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 50,000.

While driving get notice lane departure not working and thermostat registered zero, when code scanned, states low thermostat temp and able to reset with code reader. Will reoccur in minters to days later. This is an electrical issue to to the ability to reset with a code scan tool, but also a safety issue since it also effects the electrical safety ability associated with the sensor.

When I’m driving a warning comes on my DIC screen that says “ACTION REQUIRED STEERING ASSIST IS REDUCED DRIVE WITH CARE”. The AC does not work and the temp gauge goes to cold with the radiator fan blowing at full speed. My car has done this since I purchased it used in 2019 and when I call dealer they say there is no recall and $1200-1800 to replace a sensor and thermostate. I have not had the issue fixed yet.

There is a continuing issue with the shifter causing a "Shift to Park" message that is resulting in the vehicle electrical system not turning off. This is causing the vehicle to drain the battery and not able to lock the vehicle while the "Shift to Park" message is displayed on the instrument panel. Concerned not only what is mentioned above but mainly concerned in not knowing if the vehicle is truly in park that may cause the vehicle to roll.

The contact's boyfriend owns a 2017 GMC Acadia. The contact stated that while driving at various speeds, the vehicle jerked abnormally while depressing the accelerator pedal. There was no warning light illuminated. The vehicle was taken to an independent mechanic who was unable to determine the cause of the failure; however, the mechanic stated that the failure was related to the transmission. The contact called two local dealers about the failure, and both stated that the vehicle could not be serviced in the near future. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 106,000.

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 NHTSA. 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.

The middle row passenger side bucket seat seems to have a seat buckle failure. We have had a booster seat professionally installed for over a year. I check daily before my son gets in the seat that the seat is properly secured, but this morning it was loose. The shoulder belt that you have to pull all the way out to ratchet. It in place was completely un ratcheted and free to move. The buckle was still buckled completely, and the only way the shoulder belt should have been able to be loose like that would’ve been completely unbuckling and letting it retract all the way. The seat buckle was never unbuckled whatsoever. It seems like that ratcheting mechanism somehow failed and released the lock on the shoulder belt which was supposed to be holding the car seat in place. To properly resecure the car seat, I needed to unbuckle and allow the seat buckle to completely retract back into its normal position before pulling it back out to route through the car seat and re-ratcheting it tightly. The locking mechanism appears to be working now, but I am concerned that without unbuckling the seat buckle it just randomly Unlocked on its own.
