The contact owns a 2017 GMC Acadia. The contact stated that on various occasions after shifting into park(P), it was not recognized and the "Attention Required, Shift to park(P)" message was displayed. The contact stated that multiple attempts at shifting the gear into neutral(N) or reverse(R) were needed for the park(P) to be recognized and for the contact to be able to turn off the vehicle. The contact also stated that while driving at various speeds, the transmission was slipping. The vehicle was taken to an independent mechanic, where it was diagnosed that the transmission needed to be replaced. The manufacturer was made aware of the failure. The approximate failure mileage was 150,000.

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.

The vehicle was taken to a dealer where the shifter assembly was replaced; however, the failure recurred. The manufacturer was made aware of the failure.

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.
