There was a recall for gmc premature timing chain engine recall. This recall was complete in 2011 but it did not fix the problem. The timing chain keeps breaking off the cam shaft sensor and needs to be replaced.

AIR BAGS
Received a safety recall and called Greg Lair GMC to schedule repair. Service guy told me the part is backorder. Called first of June and dealer still says part backorder. Letter said the parts were available. Is the dealership just not wanting to comply with this recall?

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.

The contact owns a 2017 GMC Acadia. The contact stated that while driving approximately 10-15 MPH, the vehicle made an abnormally loud blower motor sound while accelerating, before the vehicle lost motive power. The transmission was shifted to neutral(N) and pushed to the side of the roadway. The TPMS warning light was illuminated. The vehicle was towed to an independent mechanic who determined that the transmission clutch had failed, and the transmission needed to be rebuilt or replaced. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed there was no recall coverage or warranty coverage on the VIN for the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 132,000.

Shift to park issue. This 2019 Acadia Denali has been serviced twice for a shift to park issue:(It’s a known problem that occurs when Acadia vehicles fail to recognize that the gear shifter is in the park position). The first time was under warranty in 2022 and it has just been serviced again for the same problem. The system is the same as the older GM recall for this problem and the recall should also include this model as well but unfortunately it does not.

ENGINE
My coolant thermostat went out, causing my AC and steering assist to stop working. I have spoke to multiple other people who have had this same issue with their GMC Acadia and I believe this should be a recall. It’s going to cost me $1200 to have this issue resolved.

UNKNOWN OR OTHER
Shifting car into park and the car does not register that it is in park. Display reads "shift to park" and lights do not shut off. Car will sit for 15 or more minutes before the car registers it is actually in park. I try to start it, shut it off, of start it, put in gear and then switch back to park and shut it off but still reads "shift to park". Battery is going to die if this keeps happening. GMC should be responsible for doing a complete recall on this, especially since they are aware of the problem. I have been stranded in parking lots waiting for this car to correct itself. this has been going on for over 4 years.
