Raw complaint counts favor whichever nameplate has fewer vehicles on the road, so the cleaner lens is components: which specific part families concentrate each model's filings? For the GMC SIERRA 1500, the leading complaint category is engine (1475 filings), followed by service brakes and power train. For the TOYOTA SIENNA, it is structure:body (1123), ahead of structure:body:door and air bags. When the two vehicles cluster around the same component, the problem is likely a shared supplier or a shared federal standard under stress; when they diverge, each nameplate has its own defect signature independent of the other.

NHTSA's New Car Assessment Program gives the GMC SIERRA 1500 an average 4.4/5 crash-test rating versus 4.7/5 for the TOYOTA SIENNA, aggregated across all model years with published scores. Use the side-by-side table below as your scorecard, but do not treat it as a verdict. Recall counts tell you how many defects the manufacturer has already been compelled to remedy; complaint counts tell you what owners are still flagging today; and safety ratings tell you how the vehicle performs in standardized barrier tests — three different lenses on the same underlying question.
