The engine is spewing oil from the sides of the engine. This is causing overheating and check engine light to come on. Mechanics cannot get an error read on it. There is no oil leak coming from under the engine.

What owners say
Vehicle keeps intermittently coming up with "Power Steering Reduced: Drive with Care," during this my steering is perfectly fine, however my A/C stops blowing cold air, the temperature gauge stops working and my engine fan is running constantly. This is obviously a well known issue since googling that warning and my vehicle it comes up with the issue and what the cause is. Which the cause is from the thermostat remaining open and allowing coolant to run through the system, even when the vehicle is not overheating. I just bought this vehicle used from my local dealership and am surprised that GM has not recognized this is an issue affecting numerous vehicle. This should at the very least be put as a warranty covered issue!
Thermostat of the 3.6L LGX engine of General Motors fails. This causes systems to run radiator fan full speed and GMC Certified Service Center said can cause the engine to over-heat and damage. GMC Service center said that entire Thermostat unit (box) needs replacement and due to its location in the engine, it will take 6 hours of labor. They also recommended to flush the coolant and refill. If I google for this issue, its reported numerous times on Acadia forums and seems like a very common issue.

Please have GM also cover costs of folks who have already fixed this issue with their own money, since the cost of fix is very very high. Thanks
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. the federal safety agency 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.

My 2017 had a shift to park issue. When parked and the car is in "park" the car will say "shift to park" which causes you not to be able to lock the car, or to make sure the car will not roll away. Took the car to the dealer and had all components replaced, however they information me that this will not fix the problem as the parts are made incorrectly, so unfortunately it will happen again at some point. My second issue with the acadia is when you are in cruse control, the car will automatically apply the breaks (abruptly and hard) for no reason. Gmc says that it could be when the sensors get dirty or overheat, however it makes you very uneasy knowing your breaks can mash on at anytime by themselves when you are using the cruise control system.
