2018 GMC ACADIA Complaints

My 2018 GMC Acadia has had the "Shift T Park" alarm and indicator going off after my car is turned off and in "PARK" It only happens intermittently, but frequently enough to be annoying. The dealer and GM told me because my VIN wasn't in their recall range, they would not honor the recall. This has been happening since I purchased the car in 2018.

Battery saver ignited comes on and and the entire dash flickers and turns off ! This happened in a middle of an intersection and I could move my car. We jumped it and went to the nearest auto zone replaced the battery . It was pulling 89 amps . The next day it popped up again and we replaced the alternator. Upon replacing this there was oil everywhere! And we don’t know where it is coming from . Now shift into part light comes on !

There is a current recall on the 2018 GMC Acadia for a "Shift to Park" issue. It clearly states that GMC is aware of this issue and my vehicle is having this issue but for whatever reason, I am being told we are not part of the recall. My VIN is not coming up with it either but we are having the same issue.

Component/System: Transmission selector / electrical system (“Shift to Park” defect) Yes, vehicle is available for inspection upon request. I own a 2018 GMC Acadia. Since I purchased the vehicle used in June 2019, the car has frequently displayed a “Shift to Park” message even when the vehicle is in park and the gear shifter is fully engaged. This message prevents the car from turning off completely, leaving electrical systems running, the ignition on, and draining the battery. This issue has persisted nearly daily for the past five years. I brought the vehicle to a GM dealership in September 2020, while it was still under factory warranty, but the problem was not diagnosed or repaired at the time. The dealership could not reproduce the issue, but it continued regularly afterward. I am now paying nearly $900 out of pocket to have it repaired. Safety Risks: The vehicle does not fully shut down, increasing risk of electrical malfunction or battery failure. I am often unsure whether the car is truly “off,” which could pose a fire hazard or lead to the car rolling unexpectedly if the system misreads the gear position. This defect has also caused me to get stuck in unsafe areas, repeatedly turning the car off and on, jiggling the shifter until the system registers park. The constant battery drain has left me stranded with a dead vehicle multiple times. Reproduction / Confirmation: The issue has been reproduced by an independent repair shop and will be fixed at my expense next week. A GM dealership inspected it in 2020 but failed to diagnose or confirm the issue at that time. Inspection: The vehicle has been inspected by a GM-authorized service center. Not inspected by police or insurance representatives. Warning Messages or Symptoms: The “Shift to Park” message appears on the dashboard even after the vehicle is correctly shifted into park. This began shortly after purchasing the vehicle in June 2019, worsened over time, & still has the inability to turn off properly.

The contact owns a 2018 GMC Acadia C1. The contact stated that his wife was parking in the driveway and upon shifting into the park gear, the vehicle sensor would not register that it was in park, therefore not allowing the engine to be shut off. The contact stated that his wife proceeded to turn the vehicle on and off while continuously shifting the gears until finally placing the shifter into park, and successfully turning the vehicle's engine off. The contact noted that his wife exited the vehicle; however that moments after a loud bang could be heard, and upon inspection, the contact noticed that the vehicle rolled into the garage with the entire front bumper. No property damage was reported. The vehicle came to a stop upon impact. The vehicle was going 3 MPH at the time of the crash. The vehicle did not need to be towed. No warning lights were illuminated however, the "Shift to Park" message will display on the instrument panel. A police report was not filed. The vehicle was not destroyed. The local dealer was contacted however, the vehicle was not diagnosed as the contact was advised that the vehicles VIN was not included in any open recalls. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 90,000.

Faulty shifter assembly (shift to park) car stays on while in park because of this issue

Shift To Park appears on the dash display also with a chime warning, when the car is physically in park and the engine is cut off. The shift to park display and the chime stays on causing a complete drain of the battery.

When placing the gearshift in park a warning on the dashboard says the vehicle is not in park and I get warning bells when shutting the engine off. This has been happening for almost a month.

When putting my GMC Acadia in Park and shutting off the push start ignition the alarm goes off saying it’s not in park when it is clearly in park so I have to continuously start the car and try to keep putting it in park and shut ignition off. I googled it and saw there was a recall so took it to dealership but my vin was not included. I feel my safety is at risk as my battery also went dead stranding me in another city with my young grandkids on February 23rd, and I had a large bill to get a jump as well, I believe due to this same electrical issue! We are waiting on estimate now to get it fixed which is ridiculous as it is the same issue that is covered on many other of the same model vehicles! You should really look into this and maybe other electrical safety concerns costing consumers thousands of dollars on all these GMC vehicles it doesn’t seem fair. Thank you.

"Shift to park" warning error when vehicle is in park. Although I have heard there was a recall, I am not seeing any when I've entered my vin #. The issue has happened multiple times over the last 6 months
