Coming Soon

Cadillac XT5 1st Generation

20172024 · C1XX · suv

First-generation XT5 on GM's C1XX platform (sibling to Chevy Traverse 2nd gen, GMC Acadia 2nd gen). 3.6L LGX V6 (310 hp) standard; 2.0L LSY turbo I4 (235 hp) added on later builds. 8-speed 8L45 / 8L90 automatic. FWD or AWD. Replaced the SRX as Cadillac's volume crossover. North American production ended 2024.

Watch out: 8-speed 8L45/8L90 transmission shudder on early builds is the dominant complaint — TSB and revised valve-body parts address most cases. 3.6L LGX direct-injection intake-valve carbon buildup at high mileage is expected.

Full clubhouse — owner Garage Lineage, common problems, year-by-year notes, and product picks — is on the build list.
