Summary Verdict

The 2005 GMC Canyon, particularly with the 3.5L engine, can experience issues with its timing chain and intake manifold. The automatic transmission is also a point of concern, with reports of slipping gears and torque converter problems. Suspension components like ball joints and leaf springs may require attention over time. Electrical gremlins, often related to the BCM, and rust on the body and frame are also noted concerns. While not plagued by widespread catastrophic failures, potential buyers should be aware of these common repair areas and factor them into ownership costs.
