GMC Acadia 2nd Generation

2017–2023 · C1XX · suv

Second-generation Acadia on the C1XX platform (sibling to Cadillac XT5 / XT6, Chevy Traverse 2nd gen). Downsized from 200.8 to 193.6 inches long. 2.5L LCV I4 (193 hp) base, 3.6L LGX V6 (310 hp) optional. 2.0L LTG turbo I4 briefly offered. 6-speed (2.5L), 9-speed 9T65 (3.6L). FWD or AWD. AT4 off-road trim added 2020.

Watch out: 9-speed 9T65 automatic shudder/harsh shifting on early 3.6L builds is the dominant complaint — software reflash + revised valve-body components are the standard fix. 2.5L LCV timing-chain stretch on high-mileage examples is the secondary concern.
