2024 GMC Acadia complaints

I bought a brand new GMC Acadia at Thompson GMC in Raleigh NC. From day 1 I have been having a issue with the tire pressure sensors disconnecting from the system. Thompson GMC was giving me attitude for bringing it back so many times so I brought it to Leith GMC in Wendell NC for diagnoses. Both shops referred to GM TSB (Technical Service Bulletin) PIT6188 which they both tried the reprogramming with no such luck. I was advised to wait for GM to come up with a fix and refused a loaner for the time unless I paid (GM customer care confirmed I would have to pay up front for a loaner). It is now 6 months later and I am still driving a vehicle where lights still come up on the dashboard and no fix. I get no where with the dealerships and GM customer care (case # 9-14086984106) advises me I have to keep bringing it to the dealership. No one can give me a update on when this will be fixed and I am constantly getting a run around. Please help.

On our drive home from Colorado back to Wyoming. Our 2024 GMC Acadia AT4 had 3,076 miles on the SUV. No problems leading up to this point. Has we crossed the Wyoming boarder emergency light comes off shut vehicle off immediately. Oil pressure low. I pulled over on the side of the road called OnStar for a tow truck. This all took place [XXX] on Sunday. Dealership says the oil pumped failed. GMC needs to issue out a recall for this. I see other people out there deal with the same issue online. It really sucks I put down nice down payment for our family vehicle. Then this happens. We are down a SUV now, I have to pay the taxes on the car $3,239.40 and still making a payment on a car that I can’t drive.

I was driving and making a left turn at a traffic light when all of a sudden, every light lit up on my dashboard. Then the dashboard turned completely black along with the radio screen. When the dashboard went black, I tried to stop by hitting the brakes to pull over. The brake pedal went all the way to the floor, and I had zero brakes. I was able to coast to a dirt shoulder where the vehicle stopped due to friction and gravity. The brakes never worked to aid in stopping the motion of my vehicle. I had my vehicle towed immediately to the dealership where I bought it.

THE SUPER CRUISE RANDOMLY KICKS OUT SOMETIMES IN THE MIDDLE OF A LANE CHANGE AND HAS EVEN KICKED OUT GOING OVER A HILL AND SENT THE CAR INTO THE OTHER LANE OF ON COMING TRAFFIC ITS HAS BEEN TO THE DEALER 3 TIMES IN THE FIRST 3 MONTHS OF OWNERSHIP FOR A TOTAL OF 18 DAYS IN THE SHOP GM SAYS THERE IS NO FIX AT THIS TIME. THIS HAS HAPPENED NUMEROUS TIMES

GMC told me I needed to contact you regarding my third row seats not going down flat. The headrest will not flip forward causing me not to be able to use my vehicle as intended.

The automatic braking system activates when there is no danger of collision or impact. During heavy rain, backing out of a parking space, with no hazard activating the emergency braking system near your vehicle, the emergency braking system will activate every 2-3 feet driven- sometimes occurring 6-8 times when trying to back out of space. This is a safety hazard because you’re left sitting in a roadway with no control over vehicle. Your chances of being hit by oncoming traffic, because your vehicle stops itself over and over, is high. Not only is the automatic braking jarring, you have to sit in oncoming traffic while the emergency parking brake releases. The emergency braking system will also activate without cause when backing down a hill, even on a sunny and clear day. This poses a danger when trying to parallel park, on a hill, in busy traffic. Have not reported to service center or manufacturer. Seems to be a system sensitivity issue that is a non serviceable issue. Problem occurred when vehicle under 1,000 miles and continues at 5,000 miles.

When lowering the 3rd row seats the headrests will not fold down, making it impossible to lower 3rd row seats fully

Safety Restraint System Service light alert comes on at start up. I purchased this vehicle july 20th and returned vehicle to dealer for service on sept.5. I was informed the steering wheel air bag and coil are faulty. The repair parts are on back order and would take at least 5-6 months to get. I contacted GM customer service and was told the air bag system should still function according to GM. I have had this vehicle @ 2months, I don't feel comfortable letting my wife drive this vehicle or transporting my grandkids in it.

While backing out of my driveway the auto braking went off 3 times and there is nothing behind me. i took the vehicle to the dealer and they just put all emergency braking systems on alert. my sales person took a gmc acadia up north and the same thing happened to her.

Left rear tail lamp failed after only 90 miles. It is available for inspection upon request. This tail lamp also contains the left turn signal, so when turning left, the signal flashes faster. The dealership has been notified of the issue and has inspected the issue in question. There were no warning lamps indicating the lamp was not functioning until I turned my left turn signal on. Now, there is a check left tail lamp indicator every time I use my left turn signal. I have been waiting on the replacement part for approximately 6 weeks with no ETA on a resolution, all while GM thinks its ok and safe that I drive my car without a left rear turn signal and brake lamp.

2024 brand new Acadia Denali trim with 1k miles was brought in to the dealership because of 'popping' and 'grinding' noise when turning, most loudest when turning to and from the right. It was also very much felt on the steering wheel. Dealer took apart the front right strut assembly and said that it was not 'installed' properly, causing the springs to hit the fender everytime the wheels turned. They inspected it said that nothing needed to be replaced, installed it properly, test drove it and determined that it was fixed. Driving home, I sped through potholes and bumps, especially during turns, to really test their repairs. Luckily, the sound was gone, steering was smooth. And I hope it stays that way. Out of curiosity, I took a picture of the strut assembly post Repair You can see the coil is bulging out of place from the strut. This is only in the right side. The pictures show the suspension with wheels fully turned to the right, left, and pointed straight. The picture even shows the part of the fender where the spring made contact with. I communicated in online groups of acadia owners and they said it’s also the same issue, wherein that they experienced the symptoms themselves or the struts look misaligned already. I believe this is a concern GMC should address the soonest as it could lead to road hazards for everyone involved.
