" steering assistant reduced, drive care" " power steering ,drive with care". My car has been properly maintained, and has no issues, but this messages that keep coming up out of nowhere. And when it comes out my steering wheel gets very hard and stiff, causing me to almost get in accident in highway. This is definitely a factory defect that needs to be recalled and taken care of.
I purchased this car in May 2024 and it has done this since the day I bought it. When I shift into park and turn the car off it alerts me that I need to shift into park but it already is, I have to squeeze/jiggle the button on the shifter to make it stop. I feel this could cause some serious problems
On July 26, 2024, I was driving my 2018 Acadia, with my cruise control set to 48 in a 45 MHP zone. Nearing a bad curve, I sneezed. When this happened, I tapped the brakes to disengage the cruise control, my passengers side tires exited the road and with both hands on the wheel I tried to slowly bring my tires back to the road.

On July 26, 2024, I was driving my 2018 Acadia, with my cruise control set to 48 in a 45 MHP zone. Nearing a bad curve, I sneezed. When this happened, I tapped the brakes to disengage the cruise control, my passengers side tires exited the road and with both hands on the wheel I tried to slowly bring my tires back to the road. However, I was unable to gain control and totaled the vehicle. A witness stated that she heard a loud pop coming from the vehicle before the wreck happened. I later learned from my insurance that the vehicle had a Recall 17V516000 on it and I was never made aware of it. I believe that this was a factor in me not being able to control the vehicle.
Seemingly at random a warning will pop up on the driver dashboard “Steering assist is reduced at this time”. This will lead to a engine coolant temp reading of 0 degrees, no a/c and reduced steering functionality. Through further investigation the OBD code P0128 tells us it’s a faulty Thermostat or Thermostat sensor. Even if y…

Seemingly at random a warning will pop up on the driver dashboard “Steering assist is reduced at this time”. This will lead to a engine coolant temp reading of 0 degrees, no a/c and reduced steering functionality. Through further investigation the OBD code P0128 tells us it’s a faulty Thermostat or Thermostat sensor. Even if you get these parts replaced, the issue still comes back. I’ve seen these exact complaints at least a thousand times across multiple years of this model/make 2016,2017,2018,2019. This is clearly a manufacturers fault and needs a recall before people get hurt.
The “steering assist reduced. Drive with care” A/C turns off and fan kicks on high. Transmission temp flatlines. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Power steering reduces and the temperature gage wont work and the fan is extremely loud so it decreases the steering and increases the fan so it can cool down the engine. Others have submitted a recall form for this same problem
While driving I got the alert in my cluster that “power steering assist reduced”. I also noticed there were many other individuals in gmc forums that have had the same issue.

Numerous occurences especially recently of shift vehicle to park when vehicle has been parked, turned off and already shifted into park position. Several occurrences where almost every time within 24 hours I use my cruise control and air conditioner at the same time my check engine light will come on as well as the stability trac indicator which then causes my air conditioner not to work and inability to start the vehicle due to having a check engine light on.
I have numerous warnings, shift to park, steering, cross traffic, this endangers myself and anyone else around me, i have read several class action suits involving these problems and it could cause my vehicle to pose a danger, I have taken my vehicle in to a certified dealer and they state there is no known recalls associated wi…

I have numerous warnings, shift to park, steering, cross traffic, this endangers myself and anyone else around me, i have read several class action suits involving these problems and it could cause my vehicle to pose a danger, I have taken my vehicle in to a certified dealer and they state there is no known recalls associated with my vehicle which is strange because GMC knows that there are thousands of vehicles having the same problem, did I buy a lemon? These problems are clearly manufacture related and in no way normal wear and tare. I should not have to compensate these issues when I paid near 40,000 for it
