Summary

The 2012 Cadillac CTS presents a mixed bag of potential issues. The timing chain problems on the V6 engines are perhaps the most serious, potentially leading to significant engine damage and costly repairs. The supercharger isolator failure on the CTS-V is also a moderately expensive repair. Electrical issues such as the CUE system problems are common and can be frustrating. Suspension issues related to the Magnetic Ride Control can become expensive if multiple shocks need replacement. Overall, while the CTS offers a compelling blend of luxury and performance, potential buyers should be aware of these common issues and factor potential repair costs into their purchase decision. Addressing any of these issues can range from a few hundred dollars to several thousand.
