The third-generation GMC Acadia (Gen III) marks a major turning point for the model. After a second generation with reduced dimensions, the 2024+ Acadia returns to an imposing large three-row SUV size, moving closer to its cousin, the Chevrolet Traverse. It abandons the historic and reliable 3.6L V6 (LGX) in favor of a single engine option: an all-new turbocharged 2.5L 4-cylinder (LK0) developing 328 hp. This change aims to improve low-end torque and efficiency, although the long-term reliability of this block remains to be proven. The cabin makes a technological leap with the integration of Google Built-in and the availability of the Super Cruise semi-autonomous driving system. Overall rating: A spacious and modern family SUV, but whose mechanical youth requires caution.
The third-generation GMC Acadia (2024+) corrects its predecessor's main flaw by finally offering space worthy of the name for large families. However, the abandonment of the robust 3.6L V6 in favor of an unprecedented 2.5L Turbo 4-cylinder requires caution. Early reports suggest keeping a close eye on the AWD transfer case and the integrity of the head gasket on this new block. If buying new, an extended warranty covering the powertrain is highly recommended. For used buyers seeking absolute short-term reliability, a Gen II Acadia (2022-2023) equipped with the 3.6L V6 remains a safer and proven choice.
