Summary Verdict

The 2008 Cadillac SRX, particularly with the 3.6L V6 engine, shows some common reliability concerns related to its timing chain and intake manifold. The more powerful 2.8L Turbo V6 variant presents additional risks with turbocharger and coolant system issues. Transmission problems, such as harsh shifting and torque converter issues, are also noted. Suspension components like control arm bushings and struts can wear out, leading to noise and handling degradation. Electrical issues, primarily with power windows and the infotainment system, are also reported. While the exterior and interior generally hold up well, potential buyers should be aware of these mechanical and electrical vulnerabilities, especially when considering higher mileage examples.
