Ever since I bought this vehicle 75% of the time I put the vehicle in park and turn the car off the -??shift to park-?? warning light comes on and I have to jiggle the gear shift until it goes off and allows the car to turn off. This can take up to 10 min or sometimes starting the car and turning it off works but that is less times than not. This has been ongoing since I have owned the car.

Shift to park error light comes on when you are parking your car--cannot lock the car and all lights stay on--takes 5 or six tries --happens every time you move the car

No incident yet. Although at 68,567 miles, it should not need J0780 Timing Cover Gasket replacement costing approximately $1847. Powertrain warranty was 5 year 65,000 miles. I purchased in April 2017, so April 2022 was 5 years. Unbelievable.

I started hearing noise coming from the front of my vehicle while driving. The noise would increase in volume with speed and decrease as I got slower. I had a mechanic look at it and he said my Front Right Drive shaft is going. I looked up recalls and this is an existing recall for my same vehicle but does not apply to the AWD versions. Please force the expansion of the recall, as a drive shaft should last the life of the vehicle.

At roughly 50,000 there is a transmission line leak in the vehicle. GM has already recalled 2018-2020 model-year GMC Acadia SUVs and other models for this problem due to risk of fire. Whether it is the same cause or not, such a problem leads to the same risk.

P0128 Apparently what happens when the temp sensor on the T-Stat housing goes bad it sends a signal to the ECM that the engine is overheating, causes the temp gauge to peg to "C", shuts down A/C Compressor Clutch engagement to not exacerbate the Overheat condition and super speeds the cooling fans. Of course it's a false flag warning and the engine isn't actually running hot. At the same time a signal to the ECM also tells the Power Steering Rack that it's Super Cold out and the lube in the steering system may freeze up causing loss of steering assist. NHTSA 17-NA-158 - MAY 2017 Needed to have Thermostat and Temperature sensor replaced. Was quoted by two dealers $1400-$1700. Very deceiving for GM to have SEVERAL "tech bulletins" advising their techs how to properly diagnose this common "error"... but it's not a recall so they won't foot the bill for what is clearly a defect. Car has only 59,400 / 2017 GMC Acadia All Terrain

My vehicle has serious issues that from my research seem to be a common problem/manufacturer defect experienced by other owners of this model. I believe the defect/issue is an electrical problem. While driving, the vehicle will often have problems using it's automatic transmission. It ranges from "rough" shifting (where the car jerks while shifting gears) to situation where the vehicle fails to shift gears completely leading to the RPMs shooting up. The cars power steering and traction control system also simultaneously fail. This leads to a dangerous situation when on highways etc This issue simultaneously causes all of the warning lights on the dashboard to light up while displaying the following messages on screen "Service stabilitrak" & "steering assist reduced -drive with care" & "service brake assist" & "service parking brake". The gauges also stop responding/reflecting accurate info when this happens. I have a video of what this all looks like. This has been on ongoing intermittent problem pretty much for the entire life of the vehicle. GMC informed me that they had never heard of this when I inquired about it a dealership but searching online makes it incredibly clear that this is an extremely widespread issue that they are aware of. I have also attached a file that has a list of all error codes detected by me for this vehicle.

When trying to place the vehicle in "PARK" the message is displayed to "SHIFT TO PARK". The shift lever is in the park position, but the vehicle CANNOT BE TURNED OFF while this message is displayed. The shift lever has to be moved back and forth multiple times, sometimes for several minutes before allowing you to safely shut down the vehicle and exit. This is a known issue for GMC vehicles, yet they tell me that my VIN doesn't show the vehicle is eligible for a recall for this exact issue.

After putting my Acadia in park the DIC shows that I need to shift to park and my internals won-??t shut off. I have to wiggle the gear shift, turn the car on/off and I have also had to change gear and put it back in park before it would register it was indeed in park. Something needs to be done. I can-??t leave my car in that condition without damage being done to my SUV. This happens ALL the time.

Shift to park issue; intermittent issue. Shows that car is not in park when gear shifter is in park position. Cannot shut off or lock vehicle while this is displayed. Must constantly put car in gear then in park, attempt to shut off, and retry multiple times.

Previous complaint of Shift to Park on 06/13/19 VOQ 11219862 at mileage 36270. On 12/5/21, approx miles 62099 same problem with Shift to Park. Was scheduled for service on 12/06/21 at Adams Buick GMC in Richmond, KY and mentioned the problem and previous complaint. Was told that it had been over a year ago but that they could fix it and charge me $152 for part & $315 for labor. It was less that 26000 miles driven since the last issue. After last complaint, the dealer contacted GMC and the part was replaced at no cost under bulletin for concern # 5 145420 and they replaced the transmission control assembly. This is an ongoing problem with GMC and I don't think that every 26000 miles I should have to pay to replace the same part when GMC knows it is a problem by the numerous complaints. In fact while I was getting my vehicle serviced, I spoke to another lady there who had the same problem with her vehicle. Had I not caught the message, I probably would have had to replace my battery or my vehicle could have rolled into the house. There were no warning lamps or messages prior. GMC needs to step up to the plate and issue a recall because they have numerous vehicles with the same problem. My vehicle has undergone this malfunction twice and I find it unacceptable and know that I can't afford to pay $467 every 26000 miles for an issue that GMC is clearly aware of but won't address because no one has been killed by the issue as of this date to my knowledge, but it's going to happen sooner or later if the issue is not addressed properly.
