2023 Chevrolet Colorado
WT / LT / Z71 / Trail Boss / ZR2 (4th gen ZH2, 2023–present)
Low Risk

The 4th-gen Colorado is a complete redesign from the 3rd gen — new 2.7T engine, significantly improved interior, and the Bison/ZR2 off-road variants. The 2.7T is a capable engine with no established failure modes. No AFM/cylinder deactivation concerns. Young enough that no widespread issues have emerged. ZR2 is particularly capable off-road.

What the VIN tells you

4th-gen Colorado (2023+) is single-displacement: every trim runs the 2.7L turbo I4, so the 8th VIN digit distinguishes output tune, not a different engine. K = L3B (237 hp Turbo / 310 hp Turbo Plus), C = L2R (310 hp High-Output on ZR2/Trail Boss). Both pair with the 8-speed (8LXX) automatic; there is no V6 or diesel in this generation. 10th digit P = 2023 (R = 2024). Confirm the RPO at vpic.nhtsa.dot.gov.
