ELECTRICAL SYSTEM, UNKNOWN OR OTHER
SHIFT TO PARK Warning comes on & you can't lock the vehicle nor will it shut off completely. I've had to start & reverse several times before it engages/recognizes that it is in park. OBVIOUSLY this is a KNOWN issue by reading all the other posts relating to this. Please issue a recall....

LANE DEPARTURE: BLIND SPOT DETECTION, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
Side Detection Malfunction Message on Dash. Blind spot and cross traffic alerts not working. Vehicle has a blind spot on the driver's side and without this alert, I have found that vehicles appear to not be there but actually which causes issues with merging traffic and lane changes leading to potential collisions. Dealer replaced the side detection modules under warranty and special policy because of water intrusion into the modules. This exact same symptoms and parts have occurred and replaced 5 times, and a 6th is currently needed. All work was performed exclusively at GMAC dealer and vehicle is accident free. GM issued a special policy that covered this specific repair, and the vehicle now needs to it done a 6th time and GM has refused to assist saying vehicle is out of special policy. I have requested that GM inspect the vehicle but no response. I contacted GM and they declined assistance. I currently have the feature turned off because it was providing an error message on the dash and false alerts. I don't believe that GM actually has a long-term fix for this safety issue.

SEAT BELTS
The contact owns a 2022 GMC Acadia. The contact stated that the rear passenger side seat belt and driver's side rear seat belt failed to fully extend smoothly while passengers were attempting to buckle the seat belt, or while attempting to secure a car seat inside the vehicle. The contact stated that while pulling the seat belt from the retracted position, the seat belt locked up. The contact had to release the seat belt and then attempt again to securely buckle the seat belt. The contact stated that the rear passenger’s seat belt retractor failed to lock in place while securing the car seat. The contact stated that the belt was very loose. The contact stated that the driver's side rear seat belt was also difficult to secure the car seat. The contact had taken the vehicle to a local dealer, where it was diagnosed, and determined that both seat belt units needed to be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was 42,745.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
1. The electrical system and driver-assistance/safety features malfunctioned, including intermittent power loss and dashboard system failures. The vehicle is available for inspection upon request. 2. The malfunction caused the vehicle to lose power to the braking system while driving, which created a risk of collision. Essential safety features such as power steering, brakes, and warning systems were impacted, putting both myself and other drivers at risk. 3. Yes. The issue has been reproduced and documented by the dealership during multiple service visits and reported to GM customer service. However, the safety claim was denied by GM and I have been advised to continue to drive this unsafe vehicle. 4. The vehicle has been inspected by the authorized dealership and GMC technicians. It has not been inspected by police or insurance representatives at this time. 5. Yes. Warning messages appeared on the dashboard, including system errors and power failure alerts. These issues first appeared around 20,000 miles, and have recurred intermittently since then. I have communicated with the dealership where the car was purchased and GM corporate requesting replacement with a safe and reliable vehicle. To date, I have not received a satisfactory resolution. I have researched and found that other 2024–2025 GMC Acadia owners are experiencing the same issue. This vehicle is unsafe to operate until GM identifies and resolves the defect. Losing control of the brakes constitutes a catastrophic safety failure that makes this vehicle unfit for road use. Immediate investigation and corrective action are necessary to prevent potential accidents or injuries.

SERVICE BRAKES
My vehicle only has 12,000 miles and it’s a 2024 and the brakes are constantly squeaking. I’ve reported this multiple times at my dealership and they are stating “this is normal and because of the new heavier materials there is not a fix for this.” I’m really concerned about this as it’s a safety issue. This car is also too new to be having this type of issue. I’m also apart of a owners forum and several owners are having the same issue. For the report today I’m putting the most recent date but as stated I have reported this several times with my local dealership Group 1 GMC here in Houston, Texas.

STEERING
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!

BACK OVER PREVENTION: WARNINGS, FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
Shift to Park light remains on after you’ve put the car in “park” which could potentially run the battery down. Car does not recognize when it is in “park”. Have to “jiggle” the gear a bit, in hopes that it turns off.

POWER TRAIN, FUEL/PROPULSION SYSTEM
Vehicle will shutter or buck at variable speeds like, 35-38 mph, 40-45 mph and so on. if I take my foot of the gas and reapply it will shutter buck again at almost any speed. I took it to a mechanic and there are no codes, no check engine light. Shop recommended changing the transmission fluid so we did. Car still responds the same way, shutters and bucks when reapplying fuel pedal or slow acceleration.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, POWER TRAIN
Shifting to park and vehicle stating the vehicle is not in park, won't let me turn the vehicle off. Transmission going out, brought to many shops letting me know that the transmission is not working properly but won't give an engine light if anything is wrong with vehicle, Wont show on readers what is wrong with vehicle. Electrical, Doors will automatically lock and unlock most times lock and locks me in the vehicle having me have to climb through the windows and having to leave my windows open or locks me out the vehicle and can only get in by climbing in the trunk. Testing has been done and brought to GM to figure out the issue, and they replace the computer in it but still has the problem. I have had shops tell me these are all huge issues that needs to have a recall because my vehicle is not the only GMC Acadia that does all this. How is any of this safe for me and my kids.

FUEL SYSTEM, GASOLINE
The contact owns a 2020 GMC Acadia. The contact stated that while driving at various speeds, the vehicle stalled. There was no warning light illuminated. The contact stated that while his wife was driving at an undisclosed speed at an intersection, the failure recurred, and the vehicle stopped in the middle of the intersection. The vehicle failed to restart, and the driver was unable to pull over to the side of the road. The vehicle was towed to an unknown dealer, but was not diagnosed because the contact declined to pay the diagnostic test cost. The vehicle was then towed to the dealer where it was purchased, and the fuel pump module was replaced; however, the failure recurred 2-3 months later. The contact stated that the vehicle had failed to start. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 104,000.

I have a 2021 GMC Acadia that keeps saying steering assist not available. But when it does this, the temperature gage stops working and so does the AC. After you turn the car off the fan still runs for at least 10 minutes.
