STEERING
"Steering Assist Is Reduced – Drive With Care" warning appeared while the vehicle is in motion. This may require increased steering effort and could affect a driver's ability to respond to changing traffic conditions. Any steering-related warning that appears unexpectedly while driving deserves serious attention. P0128 code was shown. The cause was a faulty thermostat housing assembly and needed to be repaired. This is an extremely common issue in this vehicle across many years and needs to be investigated.

STEERING
Steering assist reduced is the warning. The AC will no longer work and the fan runs constantly. From what I’ve read, it is a popular problem for Acadia owners and the thermostat and sensor has to be replaced. We have not been able to replace ours yet because of the cost.

STEERING
When I’m driving on the highway, I get a message on my dashboard saying steering assist reduced, drive with care. I have taken to the GMC dealership and they will not cover this repair even though it would be covered for 2021 GMC. When this happens, my car makes a loud noise and my steering wheel does not feel right. I do not feel safe.

POWER TRAIN
Gear shifter is not registering that the vehicle is in park. Because of this issue I have to sit in the vehicle for up to 15 mins trying to get it to register that it is in fact in park and can turn off. If I didn't take the time to do this, it would kill my battery. Unfortunately with the heat index, the vehicle gets hot very quickly and im now worried about getting hot stroke trying to get it to register it is park. This is a known issue with the vehicle that has an active recall for other vin numbers with the same issue.

TRANSMISSION BEGAN HESITATING AROUND 1800RPM WITH ONLY 92,000 MILES SHOWING ON THE ODOMETER. IT FEELS LIKE A FLUTTER AS THE TRANSMISSION SHIFTS INTO THE NEXT GEAR. I HAVE HEARD THE 2016 YEAR GROUP HAS HAD TRANSMISSION PROBLEMS. BELIEVE A RECALL IS JUSTIFIED.

ENGINE
Shortly after purchasing my 2019 GMC Acadia with approximately 52,000 miles, the vehicle displayed a "Steering Assist is Reduced. Drive with Care." warning message and illuminated the check engine light with diagnostic code P0128 00 (Engine Coolant Temperature Below Thermostat Regulating Temperature). I disconnected and reconnected the battery, after which both the warning message and check engine light disappeared. However, the engine coolant temperature gauge then began behaving erratically. On multiple cold starts, the gauge would immediately indicate that the engine was already at normal operating temperature even though the engine had been sitting long enough to be completely cold. This led to a diagnosis of a thermostat and/or engine coolant temperature sensor failure. After researching the issue, I found many other owners reporting the same thermostat and engine coolant temperature sensor failures. I believe this is a widespread defect that should be investigated because incorrect coolant temperature readings can prevent the driver from knowing the true engine temperature and may result in improper engine temperature regulation, overheating, and possible engine damage.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Shortly after purchasing my 2019 GMC Acadia with 52,000 miles on it, my wife parked the vehicle in our driveway and shifted the transmission into Park. When she pressed the push button to shut the vehicle off, the instrument cluster displayed a "Shift to Park" message even though the shifter was already in the Park position. Because the vehicle did not recognize that it was in Park, it would not shut off completely. The radio remained on, and the doors could not be locked. The only way to get the vehicle to shut off was to repeatedly shift from Drive to Park until it finally recognized Park. This occurred multiple times. After researching the problem, I discovered that many other GM owners have experienced the same "Shift to Park" failure. I believe this is a widespread defect that should be investigated because it can prevent a vehicle from shutting off properly, leave electrical accessories powered on, drain the battery, and prevent the vehicle from being secured when parked.

ELECTRICAL SYSTEM, POWER TRAIN
Problem 1: I got the car 2 years ago, and it keeps telling me to "Shift to Park" even though its in park. That's been happening for the whole time I've had it. It does throw a code for it on the scanner machine. I have to shift it back and forth sometimes 3 times and sometimes 17 times. It just keeps beeping over and over and won't shut off. I am having a mechanic look at it Tuesday but hoping it doesn't cost a lot. But no recalls on my car. Problem 2: For the last 4 months or so it keeps saying steering assist is reduced drive with car. It's being looked at Tuesday as well. I have 109K on my car, and got it at 86K.

I believe my car should be included in this recall. I've had the dealer check and they say it's nothing wrong with my car. 2020 GMC Acadia Fuel Pump Recall GMC has announced that 2781 vehicles have been affected by a Fuel Pump recall. General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT5, Cadillac XT6, Chevrolet Traverse, and GMC Acadia vehicles.

Thermostat and cooling sensor went out on my car. GMC issued a special coverage bulletin for 2021 Acadia since it's a widespread issue but not the 2020 (mine) which is also a widespread issue looking online. The repair is over $1000 and should be covered!

At low speeds the brakes squeal horrendously. We have taken the vehicle to the dealer multiple times and each time they state that the brakes are fine. A vehicle with this low of miles should not have squealing brakes since new.
