Should You Buy the 2012 Cadillac CTS?
The 2012 Cadillac CTS offers a compelling blend of luxury, performance, and style at an attractive used price point.

Elevated Risk Zone
This is where the infamous 3.6L timing chain issue often surfaces. A pre-purchase inspection by a Cadillac specialist is non-negotiable. Expect increased wear on major components and budget for potential higher-cost repairs.
High Risk Zone
Beyond this point, virtually all major components have a higher risk of failure. Engine, transmission, and differential are all potential liabilities. Only consider vehicles with impeccable service records, especially concerning the timi…
