general problems of the 2019 GMC Acadia - part 2

The contact owns a 2019 GMC Acadia. The contact stated while driving at an undisclosed speed, the vehicle hesitated to accelerate with the "steering assist reduced, drive with care" message displayed. Additionally, the temperature gauge remained on cold. The vehicle was taken to the dealer; however, no failure was found. The failure recurred, and the vehicle was taken back to the dealer, where it was determined that the thermostat needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 44,000. The VIN was not available.

While driving the temperature gauge shuts down completely to c - the check engine light comes on and a message appears on the dash saying "steering assist reduce drive with care". Any air conditioning goes from cold to hot and the fan under the hood goes to high automatically and wont shut off. We have been informed that this is a known error that has existed for a long time now, with no recalls to date. I cannot schedule my vehicle for repairs yet because I do not have the money to pay for the repairs. They are saying that the placement of the thermostat and sensor, which need to be replaced in order to fix this problem, are located in a very difficult spot to get to. Saying that it will take upwards of 4-5 hours to get everything fixed, which increases the amount of money to fix this issue. My 2019 GMC Acadia just started doing this about 2 months ago and I have 54000 miles.

Every time I go to turn off the engine it say shift to park and then I have to restart the truck and keep putting the shifter into park a couple of times for it to not happen.

I’ve had 2 issues with the thermostat going bad. The official part is called the water outlet assembly that includes the thermostat. I’ve also had several others tell me they have had this issue.

About five months ago, my GMC Acadia started displaying a warning when I would put the car in park, and try to turn it off. The engine would shut off, but the electrical portion of the car would stay on, and would not turn off, because the warning displaying said "shift to park". I have tried every conceivable way to try to get this to go off, but nothing works. My car has stay on for upwards of two and a half hours, to the point where my battery died in the car and left me stranded. There have been numerous accounts of this, as I had read them on forums, yet still no resolution has been published. I have tried taking it to be inspected, but nothing ever comes up. I have two very small children, and if I were to be in public and be stranded because my car wouldn't turn off. . . . I would be livid. . Also, because of this warning, it prevents the doors from being locked. That is another major concern for me, considering the day in age we're in.

My vehicle would not turn completely off, I would have to start it about ten times before the warning sounds and the yellow light on the ignition switch would go off. I took my Acadia to rod hatfield Chevrolet lexington, ky. I was told that there was an internal short with the transmission shifter, the shifter and harness would need to be replaced. Considering that I purchased this vehicle new, and it has 39,793 miles I feel like it should have been covered under the warranty however, it cost me $903. 3. I have an open case with GMC who suggested that I contact you to see if my vehicle identification number could be added to for recall.

My 2019 Acadia often will not turn off because it has a shift to park issue. Apparently it is caused by a faulty microswitch in the shifter assembly that fails to signal the body control module when in park, leading to a persistent warning message, inability to turn off the vehicle and battery drain. It has been going on for at least 4 years. It appears there is a recall for this problem but when I search my VIN number a recall does not come up. There are many posts that say "certain" models in years 2017-2019 but why not mine? it is definitely a safety issue because it does not turn off.

Car automatically shuts off when driving multiple occurrences of this happening.

I purchased my vehicle brand new off the truck in March of 2020 with zero miles on it. Feb 2021 in negative degree weather, the heat on my vehicle stopped working. I called my local gm dealership and they told me they needed to diagnosed the vehicle. They had kept my vehicle for two weeks trying to diagnose the vehicle. It turned out to be the thermostat. They replaced that part on my vehicle. Now Dec 2021 I again have experienced the same problem this time it was in a blizzard. Dealership told me it cant be the same problem, however it will be another two weeks before they can get my vehicle in for service and do not have a loaner vehicles for use. I purchased a new vehicle with warranty as I have two small children and am currently pregnant.

Thermostat is repeatedly going bad. Throws steering assist reduced. Had it replaced twice and it’s bad again.
