ENGINE, FUEL/PROPULSION SYSTEM
May 2023 we took the car to the GM dealership for a electronic recall. We reported a rattling noise at that point in time. Whatever repair was done that the car ran w/o any noise for nearly a year. April 2024 the catalytic converter failed at just 61K miles on this vehicle. The mechanic at the same dealership noted a broken mounting bracket and replaced the catalytic converter. October 24 2024 at 76K miles the car started making the same noise. The mechanic at the same dealership noted a loose mounting bracket due to an excessively vibrating catalytic converter, a crack on the cat converter, a leak and sequentially damaged front pipe. They noted they made all of those repairs. They noted they test drove the vehicle and verified the car was repaired. October 26, 2024 after those final repairs the car made a loud revving noise and emitted a smell of sulfur. The next day the car died on the road while driving. Every system of he vehicle shut down and I narrowly avoided getting hit from behind. On 11/2/24 We had the car towed to the dealership again. The mechanic noted the recent replacement on the cat converter & oil had leaked intermixing. That caused the motor to seize and the car to stop working while I was on the road driving. I can't imagine what could've happened to me had it stop on the highway at 65mph.

UNKNOWN OR OTHER, FUEL/PROPULSION SYSTEM, ENGINE
I am experiencing a recurring P04FB diagnostic trouble code on my 2023 GMC Acadia, related to the crankcase pressure sensor. GM issued Bulletin No. PIP5841C, which attributes the issue to moisture buildup freezing inside the sensor. Their recommended fix is to remove the sensor, blow out any moisture, and reinstall it. However, this is not a permanent solution—the code returns within days, suggesting an inherent design flaw in the PCV system. Additionally, the replacement sensor (Part #12718935) is on national backorder, making it impossible to obtain. Many owners across multiple GM models using this engine (such as the Chevrolet Blazer and Cadillac XT4) are experiencing the same problem, yet GM has not provided a real solution. A properly designed PCV system should not allow excessive moisture to accumulate in the sensor. Instead of addressing the root cause, GM’s bulletin merely delays the issue by temporarily clearing the moisture. This approach does not prevent the problem from recurring, and it does not fix the underlying defect. If the sensor fails or provides inaccurate readings, it can affect emissions and engine performance. The fact that the replacement part is unavailable suggests GM may be restricting access to it, possibly because they know it is defective. This raises concerns that GM is quietly managing a widespread issue rather than issuing a formal recall or warranty extension. I am requesting that the NHTSA investigate this issue, as GM's current approach does not resolve the problem. Owners should not be forced to repeatedly clear moisture from a sensor that is failing due to a design flaw. If GM has internally identified a better solution, it should be made available to affected owners instead of delaying action with ineffective temporary fixes.

ENGINE
My vehicle is 3 months old with 4650 miles. I was driving on the turnpike and without notice a warning on the dash advised that there was no oil pressure and to pull over. I had the vehicle towed to a dealer out of state since we were 3 hours from home. The dealer called today to advised the car needed a new engine. I asked what was the route cause and they advise the GM did not require the engine to be stripped to find one.

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.

POWER TRAIN
12/13/2024: While pulling onto the highway, the vehicle suddenly not accelerate past about 18 mph and would not shift gears, only rev the engine louder. Once button was pressed to engage shifting gears manually, the gear number was not shown on the dash as usual, only the letter L. We were able to drive slowly to the next exit ramp to get safely off the road. Notification about engine/transmission popped up on dash and on myGMC app. On star emailed report. Vehicle was towed to local GM dealer and assessed. Have been told that transmission needs completely rebuilt, but no description of actual issue. As of today, 2/5/2025, still waiting on parts to complete transmission rebuild.

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.

FUEL/PROPULSION SYSTEM
While driving, the vehicle shut off without warning. It was in-traffic when this occurred and subsequently blocked traffic. I tried to restart the vehicle many times. It would start and then die within a few seconds. Since the vehicle would not remain running, it was impossible to shift out of the "park" position. Since it was in "park", the vehicle could not be readily moved out of traffic. This failure is a safety hazard! The vehicle was towed from the scene. The dealer diagnosed the problem as the "Powertrain control module lost communication the the fuel pump driver module causing no fueling to engine from low pressure fuel pump U18A..." The fuel pump control module had internal communication circuit failure. GMC module 13554820 was replaced.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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. I don't know what to do. can you all help us (Please). Thank you all so very much.

VISIBILITY/WIPER
Whenever the vehicle's windshield washer is used the smell of the fluid enters the vehicle. This is particularly acute when the HVAC system is used at the same time. Since the label on the washer fluid container says the fluid is poisonous and the vapors are harmful and cannot be made nonpoisonous, I feel I should report this. I have had 4 GMC representatives confirm this is indeed happening. One rep was the Field Engineer Supervisor. All of this is documented as I have had this examined 4 times at the request of the GM customer service representative.

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!

FUEL/PROPULSION SYSTEM
While deiving in three lanes of traffic in rainy weather. The vehicle began to buck as though the engine was cutting on and off. No warming lights or abnormal noises preceded the event. The vehicle lost traction several times, but recovered. As quickly as it happened it stopped and normal driving resumed. It occurred 2 more times after approximately 1 mile of travel. I was able to limp the vehicle home, but once I shut it off it would not start again. I had it towed to the dealership and the service consultant informed me that it was the Fuel Pump Control Module that had failed and it was covered under warranty.

UNKNOWN OR OTHER
Since late 2023/early 2024, I started to notice that my liftgate was open, while the Acadia, a lease with less than 15K miles, was parked in the driveway, off. At first, I thought it was a mistake on our part, that we had accidentally hit the button on the remote to open it or had forgotten it open. As time went on, the incidences continued and I realized it was happening on its own, while the car was off! When the Acadia was at the dealership this fall for a warrant repair (a pump that GM knew was problematic but only has alerts out about for now), I mentioned the liftgate. Thankfully, the problem happened at the dealership too so workers could witness it. It's a major safety issue and a public safety issue. When the pump repair was occurring, I got a text from the dealership that the problem with the liftgate was my fault, that how I clean the inside of the car had affected the mechanics and that I would be on the hook for over $300 in repairs. I had no way to prove otherwise and opted to instead disable the open function using the dial on the driver door set to off and it has not opened. Fast forward to last week and GM has a recall on GMC and other pickups where this kind of issue appears to happening to tailgates and it instantly felt similar. I believe GMC Acadia's have the same faulty wiring and I should not be on the hook for this repair but GM should fix the problem.

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.

ELECTRICAL SYSTEM
While driving down the interstate at 70mph+, the instrument panel went black and restarted multiple times. The car continued to stay at a sustained speed, but I was unable to control anything or see how fast I was going. It appears as if the car has shut off, but it isn't. It also affects the lights. It has happened multiple times with no known cause. When I brought this up at the dealership, they said that it would be an $80 diagnostic fee and unless they can replicate the problem they can't do anything about it because it doesn't throw any error codes. There was another women in the dealership the same time as me with the exact same issue. No fix offered. Looking online and talking to others this seems like a common issue that GMC is ignoring.

ENGINE
Engine exhaust makes vibrating noise similar to a leaf blower under acceleration. TSB issued due to common issue and GM refuses to recall or fix. Broken baffle/weld inside of front muffler/resonator on exhaust system under front passenger compartment. Issue getting worse. $2500 at local dealership to fix, with GM offering “assistance” to fix issue in the amount of $742 leaving the consumer with balance. At what point will the rest of the defective part deteriorate and cause clogging issues and more damage?

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.
