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 contact owns a 2017 GMC Acadia. The contact stated that while parking the vehicle, the shift to park warning light was illuminated. 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. The failure mileage was approximately 20,000.

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.

The contact owns a 2017 GMC Acadia. The contact stated while shifting the vehicle into park and attempting to turn off the vehicle, the vehicle failed to turn off due to the gear shifter not recognizing that the vehicle was in park(P). There was no warning light illuminated. The contact pushed the Start/Stop button several times and then was able to shift the vehicle into park(P) and turn off the vehicle. The dealer was contacted and stated that vehicle needed to be diagnosed. The manufacturer was contacted but offered no assistance because the vehicle was not under warranty or recall. The failure mileage was 20,000.

- Boulder City, NV, USA

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.

- Joplin, MO, USA

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.

- Edmond, OK, USA

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.

- Stanford, KY, USA

When the placed in park, the vehicle does not recognize and will not shut off as there is a message that the car in not in park, when it is. This happens frequently. I am unsure if, although I've placed in park, the car itself recognizes that. There are times where for several minutes I cannot turn my car off even after shifting in and out of park.

My 2017 keeps having transmission issues. At the dealership the transmission fluid is burnt. The 2017 GMC Acadia limited has the same issues with the engine as the standard 2017 GMC Acadia

- Camp Lejeune , NC, USA

This vehicle has twice had parts replaced for the "Shift to Park" issue detailed in GM TSB 19-NA-206. The first incident was in April 2019, and it was repaired under warranty at about 24,800 miles. The second incident was this past week at about 50,800 miles, and this repair cost almost $800 to fix. I contacted GM customer support and was told that I could not get any reimbursement because there was no special coverage or recall for this known problem. This is completely unacceptable, since the problem is clearly a defect in parts manufacturing or assembly, and it renders the vehicle completely unusable since it is impossible to turn the car off when the car does not recognize that the shifter is in park. This is a safety issue because the driver needs to be certain whether or not the vehicle is securely parked before leaving the vehicle.

I have experienced the same problem as a multitude of Acadia owners as is well publicized via the Internet and class action lawsuits, which are now beginning initiation. My dealership tells me they have a lot of customers with the same problem which usually starts when the vehicle has around 15K miles on the odometer. The problem is the Intermittent Shift to Park display on the Information Center. It tells me that the shifter is not in park position when I go to turn the engine off, but it really is in position. When it happens I cannot turn off the automobile without restarting it. Sometimes it will turn itself off after a few seconds without any intervention on my part, sometimes more, sometimes after I jiggle the shift lever, but many times I have to restart the engine one or more times to turn the vehicle off. If the system can't be sure if I'm truly in Park position, how can it be sure that the lever is really engaged which would enable the car to roll away. I have had it back for repair service twice during the bumper to bumper warranty period to resolve the issue based on GMC guidance. That service tends to resolve it for a while but it always comes back again after a period of time. The last time I was told a jumper was installed so I should never get the problem again but it has returned and have had quite a few occurrences over the past two months. There is absolutely no pattern to the problem. What is really frustrating me is that I recently took it back again (after my bumper to bumper warranty was over) and they tell me there is another service bulletin from GMC which says the original shifter cable is too short and they need to install a longer one. Now they want me to pay $375 to install the new cable which is WRONG WRONG WRONG in order to resolve a GMC safety issue which was the result of an original design issue by GMC. I refused as this must be covered by GMC and should be the subject of a government mandated safety recall.

Shortly after I purchased my Acadia in may of 2018, it started displaying a shift to park warning when I would put the car in park. I contacted the dealership and they said it was a known issue and they had to replace the shift assembly. Well about 3 weeks ago it started doing it again. Only this time it's worse. It takes several tries and tricks to get the car to recognize it's in park and allow me to shut the car off - when the warning pops up it won't allow the car to power off so all the electronics stay on. I called the dealership and they told me because my extended warranty expired at 79,000 miles and they had already replaced the shift assembly once that there is nothing they can do and I will have to pay out of pocket for this repair even though it's a well documented issue with these vehicles.
