2024 GMC Acadia Problems

What owners report

Owners of the 2024 GMC Acadia report brake concerns most frequently, spanning both chronic squealing and complete pedal failure. Automatic emergency braking activating without an obstacle while reversing is the second most common theme. Engine oil pressure loss at low mileage and coolant leaks from the radiator hose are also recurring concerns across complaints.

   Brake squealing and premature pad wear

   • 15 complaints (25%)
   • median 7,000 mi at 1.0 yrs old (3 state mileage, few)
   • filed 2025–2026

   Owners report persistent squealing from the brakes starting at low mileage, with some complaints describing brake dust visible on the wheels and pads wearing far more quickly than expected. Dealers have inspected the brakes on multiple visits and typically advise that the pads are still within acceptable limits or attribute the noise to brake pad material composition. According to several complaints, dealers acknowledge the issue but describe it as normal, and some owners report being told a fix exists for newer model years but not for theirs. A brake pad wear sensor warning appearing while pads still show significant life remaining is also noted in complaints. Complaints describe the squealing beginning as early as a few hundred miles and persisting through roughly 25,000 miles, with many reports coming from vehicles under 20,000 miles.

   What to check: Ask whether the brakes have been inspected and whether the pad wear sensor has triggered any warnings; check for brake dust accumulation on the front wheels, which several owners report as a visible sign of accelerated wear.

   “Since we purchased this vehicle, we have continually had issues with our brakes to include dragging of the front brakes and brakes squealing when they are in use. We have brought the vehicle multiple times to the GMC dealership who is able to replicate the issue, but states that this is normal. I have filed a complaint with the GMC and they said that this is normal even though they admitted to fixing the problem in 2025 models. …”

   “My vehicle only has 12,000 miles and it’s a 2024 and the brakes are constantly squeaking. I’ve reported this multiple times at my dealership and they are stating “this is normal and because of the new heavier materials there is not a fix for this.” I’m really concerned about this as it’s a safety issue. This car is also too new to be having this type of issue. I’m also apart of a owners forum and several owners are having the same issue. …”

   Brake pedal going to floor / complete brake loss

   • 6 complaints (10%)
   • typically at 2.0 yrs old
   • 2 mention a crash, fire or injury
   • filed 2024–2026

   A number of complaints describe the brake pedal traveling all the way to the floor with little or no resistance, leaving the vehicle with severely limited stopping ability. In several accounts this occurred alongside a full dashboard blackout or multiple warning lights illuminating simultaneously. Dealers have performed software updates in some cases, though complaints note the failure recurred after the update. At least two owners report the vehicle continued moving forward at low speed and contacted another object before stopping. Complaints describe these events occurring across a range of mileages, including on vehicles with under 10,000 miles, and in some cases on vehicles used for only a short time after purchase.

   What to check: Ask the dealer whether any brake system software updates have been applied and whether the brake hydraulic system has been inspected; if the brake pedal has ever felt soft or traveled unusually far, have the system pressure-tested before purchase.

   “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. …”

   NHTSA complaint #11627973, filed 2024-11

   “When backing into my driveway the brakes failed. I was nosing the car across the street towards the neighbors driveway so I could put the car in reverse and back it into the driveway. I applied the brakes while traveling at about 3-4mph when the brakes had little resistance and went straight to the floor and the vehicle continued moving forward. Attempted to apply brakes again and the same result. Ended up hitting the neighbors parked car in their driveway. Luckily it was a very low rate of speed so there was minimal damage and nobody was hurt. …”

   Automatic emergency braking activating in reverse with no

   Mentioned in 7 of 59 sampled complaints

   Owners describe the automatic emergency braking system engaging abruptly while reversing, even when nothing is behind the vehicle, sometimes activating repeatedly every couple of feet during a single backing maneuver. Complaints note this occurs most often in rainy conditions but also in dry weather. Dealers have been able to reproduce the behavior in some cases but report that no fix is available from the manufacturer. Several owners say they have resorted to disabling the feature entirely because of the unpredictability. Complaints indicate this behavior begins early in ownership, with several owners reporting it from the first week, and it continues as a persistent issue rather than one that resolves over time.

   What to check: Ask whether the rear automatic braking system has been evaluated and whether a fix has been applied; test-drive the vehicle in reverse on a clear surface to check whether the system activates without an obstacle present.

   “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.”

   NHTSA complaint #11614570, filed 2024-09

   “We have experienced multiple recurring issues with our 2024 GMC Acadia that raise significant safety concerns and affect the vehicle’s reliability and overall operation. First, the brake system exhibits persistent squeaking, even at low speeds or light applications. The dealership has inspected the brakes but the noise continues, raising concerns about premature wear or improper brake function. More concerning is the behavior of the automatic braking system while reversing. …”

   Engine oil pressure loss and engine seizure at low mileage

   • 10 complaints (16%)
   • median 47,000 mi at 2.9 yrs old (1 states mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2024–2026

   Complaints describe the vehicle's instrument cluster issuing a no-oil-pressure warning and instructing the driver to stop immediately, typically while driving at highway speeds. In several cases the engine seized and required full replacement. Dealers have cited oil pump failure as the cause in some complaints, and service bulletins address oil pump gear and shaft assembly issues. One complaint notes dealers described this as a known issue affecting this model year. Owners report being stranded roadside while waiting for tow service. Complaints report this occurring at very low mileage, with multiple accounts describing failures between roughly 3,000 and 7,000 miles, typically while driving at highway speeds.

   2 related service bulletins

   What to check: Ask whether the engine has been inspected or replaced under warranty and whether the oil pump service bulletins have been addressed; check service records for any oil pressure-related repairs or diagnostic codes.

   “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.”

   NHTSA complaint #11643383, filed 2025-02

   “While 2 hours from home driving down the interstate with a full vehicle, the vehicle alarmed and the screen notified No Oil Pressure, Turn Car Off Now . I pulled over immediately and we had to sit on the edge of the interstate for 45 minutes - a safety hazard for us and the surrounding traffic. The vehicle was towed to the nearest GM dealer, where they assessed the vehicle and advised that this is a known issue for 2024 and 2025 GMC Acadias and Traverses. The vehicle failed to move oil and the engine was seized - a significant safety hazard. …”

   Radiator hose coolant leak and engine overheating warning

   • 6 complaints (10%)
   • typically at 2.2 yrs old
   • filed 2025–2026

   Several complaints describe coolant leaking from the upper radiator hose, leading to low coolant levels and an overheating or possible engine failure warning on the dashboard. Owners report being advised by mechanics that the radiator hose quick-connect fitting is the source of the leak. A service campaign covers this condition for five years or 60,000 miles according to its description. Some owners report difficulty obtaining the replacement part due to backorder delays at dealers. Complaints describe the issue appearing at varying mileages, with some owners reporting it on vehicles with under 10,000 miles and others on vehicles approaching 30,000 miles.

   1 related service bulletin

   What to check: Ask whether the radiator hose quick-connect service campaign (TSB 11035019) has been completed; inspect the coolant reservoir level and check underneath the vehicle for any signs of dried coolant residue near the front of the engine.

   “We purchased our 2024 Acadia in June 2025. Since we have had the vehicle, it has been in the shop going on 6 times. First the sunroof seal came off, then the antenna cover fell off, the driver side rear panel had to be replaced because it was coming off. Once all this was done then the vehicle started leaking transmission fluid, took it to the dealer to get fixed, once we get it back the coolant starts leaking from the radiator hose, took it in to get repaired, now there is knocking noise coming from the engine/hood. …”

Buying note. The 2024 Acadia has an unusually high volume of brake-related complaints for a low-mileage vehicle, and prospective buyers should verify that any brake concerns and the radiator hose service campaign have been addressed before purchase. Engine oil pump issues resulting in seizure at low mileage have also been reported, so a review of service records for any powertrain repairs is worthwhile.
