Summary

The 2006 Cadillac SRX, while offering luxury and performance, is prone to several common issues. Engine-related problems, particularly timing chain wear in the 3.6L V6 and oil leaks in the 4.6L V8, can be expensive to address. Transmission issues, suspension problems with the air ride system, and electrical glitches contribute to the ownership costs. HVAC actuator failures are a common interior complaint. Overall, potential buyers should be aware of these potential problems and factor in the costs of repair and maintenance when considering this vehicle. While no recalls specifically address these issues, a thorough pre-purchase inspection is highly recommended. The severity of the issues ranges from minor inconveniences to major mechanical failures, and the cost of repairs can vary significantly depending on the specific problem and the mechanic performing the work.
