GM Built the Same Deadly SUV Twice. The Trailblazer Killed 2,473 People.
Let's talk about what happens in the first 150 milliseconds — specifically, what happens when a body-on-frame SUV designed in 2001 meets the laws of physics at highway speed. The Chevrolet Trailblazer has a fatality rate of 2.83 deaths per 100 million vehicle miles traveled. That makes it nearly twice as deadly as the Ford Explorer (1.54) and deadlier per mile than the much larger Tahoe (2.49).
But here's what makes the Trailblazer story a platform story, not just a vehicle story. GM sold the exact same bones under two badges. The GMC Envoy — mechanically identical, slightly different sheet metal — clocked 2.26 deaths per 100M VMT and 988 fatalities from a smaller 350,000-unit fleet. Add the Trailblazer and Envoy together and you're looking at 3,461 deaths from a single engineering decision.
The GMT360 platform was GM's mid-size SUV architecture from 2002 to 2009. Body-on-frame construction. High center of gravity. A short wheelbase that made it rollover-prone. And crucially, it entered the market before electronic stability control was mandated in 2012. The platform's structural rigidity meant that in side impacts, the occupant compartment absorbed energy that modern unibody designs would redirect around the cabin.
Compare across the class. The Ford Explorer — which had its own rollover problems in the 2000s — still managed a rate of 1.54 with a much larger fleet of 1.97 million. The Dodge Durango sits at a remarkable 0.54, nearly 5× safer per mile than the Trailblazer. Even the Jeep Liberty, not exactly a safety paragon, comes in at 1.22. The Trailblazer isn't just worse than its competitors. It's in a different category of danger.
The toxicology data offers no comfort. At 22.1% impairment (688 of 3,108 drivers in fatal crashes), the Trailblazer sits right at the class average. These weren't drunk drivers at unusual rates. This is a vehicle that killed its occupants through design, not behavior.
GM killed the Trailblazer nameplate in 2009, then resurrected it in 2021 as something completely different — a small unibody crossover built on the same platform as the Buick Encore GX. The new Trailblazer shares nothing with its predecessor except the name, which is probably intentional. When your old platform generated 3,461 combined deaths across two brands, you don't carry the engineering forward. You carry the name forward and hope nobody checks the archives.
We checked.
