I was driving with my cruise control set at 77 mph in the fast lane of a four-lane highway. There was no one in front of me for more than 3/4 of a mile. A car in the lane to my right apparently triggered the automatic breaking system to the point it slammed on my brakes, pushed me into the steering wheel, and slowed me all the way to 38 mph in the fast lane of the freeway. The result of this unrequested breaking caused four cars behind me to almost rear end me and pile up. The second event was going down the freeway with the cruise control set at 65 and nobody around me and the car again slammed the brakes on for no apparent reason. At this point i’m afraid to drive the car. I have zero confidence in this vehicle letting me operate the vehicle. I need help.
Transmission slips, shifts hard, and rpm gets high before shifting.
The car needs an pcm upgrade because it’s lit up a code in randomly situation. Causing the vehicle to lose the water temperature gage, power steering wheel assistance reduced and ac stop working, gmc is aware of the problem even issued a technical bulletin in 2018, but instead of inform the clients about the defective part, they want the client with this problem to pay to upgrade a defective pcm that came out from factory with problem. Note the power steering wheel assistance is part of the safety of the car. The problem always existed in the car, it toke me 2 years to find the problem.
The rear knuckles have a casting defect that does not allow the lower most forward control arm bolt to be tightened fully. This causes the bolt to be 1/8” from being fully tightened. After removing the casting defect you are able to tighten the bolt fully. The bolt broke off in the knuckle causing the tire to point away from the body at a 45 degree angle. If my wife was on the interstate doing 60 when this happened it could have been life threatening but she was only doing about 10 when it snapped.
Car stalls out suddenly after stopping. The engine oil was changed as required and there were no warning lights on the dash. Took the car to a mechanic and the mechanic said there was no oil and metal shavings in the engine, and that the engine would need to be replaced for $10,000. The car is out of its warranty and slightly over 100,000 miles.
I have this 2018 Acadia where all of a sudden, at random, the radiator fan runs on high constantly, the AC stops blowing cold air, the thermostat gauge on the dash drops to the C, and the Power Assist is reduced and pops up as a message on the dash as well. Sounds like this may be a common problem among Acadia's. It resets at random and everything appears to be normal for a while. In addition, there are no check engine lights and no codes to check. I have had this happening for over a year and had a dealership service the car but never said mentioned it as a problem. So now that it's out of warranty my and has more frequent occurrences now I''m more aware but now it's out of warranty. It comes up on an Acadia Forum as a common issue. https://www.acadiaforum.net/threads/2019-acadia-radiator-fan-runs-constantly-no-ac-power-assist-reduced-thermostat-gauge-to-cold.38774/

I bought a 2023 gmc terrian sle brand new 14 months ago. It has 30,000 miles on it. I was driving down i75 and the car turned off. No warning signs! Not to mention the car had no power! I couldn’t even put on my emergency flashers! Me and my 3 year old son luckily were able to make it through a lane of traffic and up the embankment to call for help! I had the car towed to the dealership and they can’t find anything wrong with it! The car is acting normal now but i don’t feel safe in it!
