SERVICE BRAKES
When pressing brakes to start the car the pedal goes all the way to the floor with little or no resistance. It has happened three times in 3 months. Took it to GM dealer after the first two incidents and they did a software update. Took it in again after the third incident and they did nothing.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
While using the super cruise system I am experiencing unexpected braking of the car as it thinks it is about to rear end the vehicle in the right lane it is passing in the left lane. This happened multiple times on a recent highway drive. I am worried I am going to be rear ended by cars following me or the victim of road rage as it appears to other drivers I am brake checking them while in the passing lane. Additionally the adaptive cruise control and super cruise seem to fail to detect the vehicle immediately in front of me and fails to slow down with adaptive cruise control or attempt to change lanes when using super cruise. In both instances I have to manually brake and or change lanes to avoid a rear end collision. While manually driving the vehicle I am also receiving collision alerts when overtaking cars in the right lane while I am passing them in the left. The super cruise was able to identify cars entering the highway from on ramps multiple times and would auto lane change correctly. This leads me to believe the sensors are working but software may not be utilizing correct distance analysis when slamming on brakes as it passes a vehicle. I am scheduling a dealer service call, but feel like they will tell me there are no computer errors. There are no recalls on file. The on-star monitoring is reporting no errors. Seems like a design flaw, logic error that will require a software update.

This 2024 GMC Acadia will not back up safely on a rainy day. when moving backward, when it raining the emergency braking continually engage, approximately every two feet. I took it to GM dealer service center, it did the same with them. However, they can't correct the problem and GM does not have a fix. Also others vehicle like this one are experiencing the same problem. This has been an ongoing problem since July 5, 2024 in rainy weather. I called GM customer service and have gotten no result.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When the vehicle is in reverse and you are backing the emergency brake suddenly comes on practically giving you whiplash. This happens randomly and without any obstruction or reason for the emergency brake to come on. It has happened many times. This morning it slammed the emergency brake on 4 times in a row I didn't think I was going to be able to back up as it kept kicking the emergency brake on. Based on what I have seen on the internet many 2024 GMC Acadia owners are having similar problems. GM needs to fix this!

ELECTRICAL SYSTEM, WHEELS
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.

POWER TRAIN
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.

SERVICE BRAKES, ELECTRICAL SYSTEM
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.

BACK OVER PREVENTION: AUTOMATIC SYSTEM BRAKING
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.

AIR BAGS
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.

EXTERIOR LIGHTING
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.

SUSPENSION, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.
