Summary
The 2011 Cadillac CTS has a range of potential issues, from relatively minor electrical problems to more serious engine and transmission concerns. The timing chain issues on the 3.0L and 3.6L V6 engines are a significant concern due to the high cost of repair. The CTS-V’s supercharger intercooler pump failure is also a common issue that can impact performance. Overall, potential buyers should be aware of these issues and have a pre-purchase inspection performed by a qualified mechanic to assess the vehicle’s condition. The cost to repair these issues can range from a few hundred dollars to several thousand, depending on the specific problem and the severity of the damage.
