5/5 Overall
NHTSA 5-Star Safety Rating
The dominant pattern in 2023 GMC Acadia complaints centers on the powertrain and engine. Owners frequently report stalling events, particularly at highway speeds, where the engine loses power unexpectedly, sometimes allowing a restart, sometimes not. A failed fuel pump control module comes up as a contributing factor in some of these no-start situations, and in at least one case the transmission could not be shifted to neutral, leaving the vehicle stranded in traffic until a tow arrived. Several owners also describe a clunking or thudding noise during low-speed gear changes, though technicians haven't always been able to confirm a fault. On the electrical side, the infotainment system draws repeated mentions, owners describe the touchscreen freezing, the display shaking, and Bluetooth or Android Auto connections dropping inconsistently.

With Injuries
By System
The 2023 GMC Acadia has 5 recalls, the most serious involving the transmission's half-shaft, which can disengage and cause a sudden loss of drive power or allow the vehicle to roll away when parked.
Two separate recalls address this half-shaft issue, both pointing to the same real-world danger: the driver-side or right-front half-shaft can pull free from the transmission, leaving the vehicle without power or, if parked, able to roll unexpectedly on any incline. Prior repair attempts did not fully resolve the problem, which is why it appears under more than one filing.
The next concern involves the windshield, which on some vehicles was installed without adequate urethane sealant bonding it to the body. A windshield that is not properly secured can work loose over time, sometimes showing up as wind noise or a water leak, and can detach in a crash, increasing the risk of injury to occupants.
The final recall is a compliance issue: the certification label on the driver-side door pillar may have tire size information printed in a way that is too faint or small to read clearly. If a shop or owner cannot read the label, the wrong size tires could be installed, which affects handling and braking.
