EXTERIOR LIGHTING
Rear driver's side brake light/turn signal is out. This is the second time in under a year. Local GMC dealer is not able to replace it within a reasonable amount of time causing a safety issue. This is a well known issue to GMC which is why the part is on back order. No other dealers in my area have the part in stock.

FUEL/PROPULSION SYSTEM
The Fuel Pump Control Module failed. It happened when the car was parked. The car would crank, but would not start. We were stranded far from where we live. It was hot and we had to be towed to a GM Dealership. This part could have failed on the hi-way with awful results. The Dealership verified the defective part. We have the old part as needed. Lots of lights flashed and went out. The Engine Light stayed on. The Gas Gauge was not reporting the correct amount of gas in the tank, but seemed to correct itself before the part failed..

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, STEERING, SERVICE BRAKES
Car driven off the lot 06/14/2025 On Sunday 07/06/25 (21 days from purchase) while driving home from a 30 minutes away from home trip with 3 young children with me, the car gave multiple alerts and service warnings. "Service Brake Assist" and "Service ECS" Lights / Symbols related to the following were also displayed: Traction Control System (TCS)/ Electronic Control Stability Light, Anti-lock Brakey System (ABS); Brake System Warning Light, Forward Collision Alert and BREAK light I stopped the car immediately and pulled to the side of the road. After restarting vehicle, lights were still displayed and service alerts still on. Power steering was very diminished and the breaks were struggle to break. Acceleration was also impacted and every time I breaked it appeared as though the car was trying to accelerate. I was able to drive the car home slowly following back roads. On Monday 07/07/25 I called the dealership and arranged a tow to their facility. On Tuesday 07/08/25 after multiple "unavailable to take your calls" I was finally able to connect with a service technician who indicated the break master cylinder needed to be replaced. I was not given an ETA on the completion of this repair. I have owned the car for 21 days. It has 1073 miles on it!!! I have 3 young children! The original route home was via a very heavy interstate! What if the brakes failed me while driving an interstate! I praise God I was able to get home safely with my children

STRUCTURE
The contact owns a 2023 GMC Acadia. The contact stated that after purchasing the vehicle, it was discovered that there was water and condensation inside the rear middle brake light assembly. The contact later discovered that during rainstorms, rainwater had leaked into the rear seating and hatch area of the vehicle. The vehicle was taken to the local dealer who determined that the failure was due to a manufacturing structural error and the vehicle needed body work to be performed to correct the failure. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 5,200.

EXTERIOR LIGHTING
My 2025 Acadia Denali's Main tablet sized screen is impossible to view in bright daylight. This screen has controls for most of the vehicle's settings. If I want to change something such as the temperature setting, I can't see the proper button. This is clearly a safety issue as taking eyes off the road for an extended period just to make a simple setting change is a recipe for disaster. My dealer claims there is no solution as they are all like that.

POWER TRAIN
Driving out of state. My 2021 Acadia with 41,172 miles. When pushing the gas to go there is slippage when trying to accelerate. MY car went automatically into neutral saying transmission and then not start. After a rest period it would start then repeat the same issue. In bumper to bumper traffic on I75. The most Terrifying & UNSAFE place to be at 75 to 80 mph. We happened to be driving up on construction and slow down traffic. When the car stalled. Towed it to a transmission place because of code. They replaced the DTR1 PCM.

FUEL/PROPULSION SYSTEM
Driving on rt 95n in Ga. Going 70 mph and vehicle just bucked and shut off. At the time I was in the middle lane and almost got hit by a tractor trailer while I was trying to get to the right side of the road. Called general motors roadside assistance and they supplied a tow company to tow me to a dealer in Ga. About 35 miles away unfortunately it was Sunday dealer was closed and I had to get a taxi to take me to a hotel with all my luggage. On Monday morning when the service dept. Opened they advised me the fuel pump module had failed and would be replaced. Luckily most times when vehicles shut off with push button electronically shifted transmissions you can't put the vehicle in neutral to move or tow but after many tries it went to neutral(according to the tow driver) also after researching my vehicles failure I found this is a wide spread problem among many gm suvs and trucks! Hopefully a recall is in the future before someone gets killed!!

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
After having my 2025 GMC Acadia Elevation for 2 weeks, I turned it on and six lights on the dash lit up. ESC, ABS, Tractions Control and more. I was leaving a store at the time this happened and drove home. Also, my cruise control would no longer work. Took my Acadia to the dealership the following business day to be serviced, only to be told a week later that the master brake cylinder needed replaced. This part of course was on back order. My new part arrived two weeks later, only to discover that two additional one-time parts (seal and reservoir) are now needed. These parts are also on back order with an estimated ship date of mid to late July.

UNKNOWN OR OTHER
My 2022 Acadia does not go into park at times even though the control button shows that it is in park. On May 15, 2025, I pulled under my carport and put the car in park. As I reached for my purse in the passenger seat, the car started moving forward even though it was in park. It ran through my privacy fence and injured my daughter who happened to be on the other side of the fence. She had some pretty severe bruising and scrapes on her hip, thigh, and upper body. The pain is bad enough, but her arm and shoulder was injured. It continually feels like something running up and down her arm. This is three weeks later and she still has the problem. The horrifying fact is the reality that I could have killed her through no fault of my own. I had the car towed to the dealership because I was afraid to drive it. Of course, the service department said they ran a test through the electrical system and found no problem with it. They brought my car to the front and told me there was nothing wrong with it. In fact they said they had not heard of that kind of problem. When I have to park I find a parking spot that would be least likely to have someone walk in front of it. If I have to park facing anything I will not pull up fully into the parking space so if my possessed car decided to go for a joy ride while in park again, at least someone would have a running chance to stay alive. I consulted the internet trying to find a fix to the problem. What I found was that GM has had the problem for years and has no idea how to fix it, yet they are allowed to continue to sell vehicles that are a potential safety hazard to society. My vehicle is a safety hazard to me and to society. Also learned that if you take you car to the repair shop you are appeased thinking they repaired the problem and yet it continues. When your warranty runs out, GM expects you to pay for any further visits to the shop. As far as I'm concerned selling GM products could be considered A FRAUDULENT ACTIVITY!

ELECTRICAL SYSTEM
The Radio in my 2021 GMC Acadia had to be replaced due to an UPDATE Failure. I had to pay $221.32 for diagnostic and $1,580.18 for a new Radio. My Husband and I are the original owners of the 2021 GMC Acadia. My Dissatisfaction is why are some GMC products under recall for this issue but my 2021 GMC Acadia not part of the recall. The Hands free calling was not working, the GPS and also affected the back up Camera. all of these . a response is requested
