The 2026 GMC Canyon AT4 scored only Marginal on the Insurance Institute for Highway Safety’s updated moderate overlap frontal crash test, with the SUV-grade pickup specifically falling short on protection for the passenger riding directly behind the driver. The results, released September 3, 2026, cost the Canyon any chance at a Top Safety Pick award this model year.

Key Points

• The 2026 GMC Canyon AT4 Crew Cab with four-wheel drive earned an overall Marginal rating on IIHS’s updated moderate overlap front test, one step below Good and Acceptable.
• The rear passenger’s head/neck injury measures came back Marginal, the weak point that dragged down the overall score, according to IIHS’s own published ratings.
• Front driver protection remained strong: the Canyon still earned Good ratings on the small overlap front test and the updated side test.
• The truck’s front crash prevention also drew a Poor rating in vehicle-to-vehicle testing, and it missed IIHS’s Top Safety Pick designation entirely for 2026.

What Failed, Specifically

IIHS updated its moderate overlap frontal test in recent years specifically to put more weight on how well a vehicle protects the person sitting behind the driver, using a dummy positioned to represent a small woman or 12-year-old child in the second row. In the Canyon’s test, that rear dummy’s head and neck injury measures landed in Marginal territory — the restraint system allowed forces on the head and neck to run higher than IIHS considers acceptable, even though the dummy’s chest measures came back Acceptable and thigh measures scored Good, according to test details reported by GM Authority.

That distinction matters because it shows the Canyon’s structure held up reasonably well in the crash itself; the shortfall is specifically about how the rear seatbelt and restraint geometry manage forces on a rear occupant’s head and neck during the impact, not a structural collapse of the cab. IIHS has flagged this same rear-seat weakness across a number of pickup trucks in recent testing cycles, arguing that automakers have historically focused restraint engineering on front-seat occupants at the expense of the back row.

What This Means for Buyers

The Marginal rating does not mean the 2026 Canyon AT4 is unsafe in an absolute sense — it still posted Good marks in two of the three IIHS crashworthiness categories. But it does mean GMC’s midsize off-road pickup enters the 2026 model year without a Top Safety Pick or Top Safety Pick+ award, at a time when rival midsize trucks are being held to the same tougher rear-occupant standard. Families who regularly carry passengers, especially children, in the Canyon’s rear seat should weigh that Marginal head/neck rating specifically, since it is the one area where IIHS found the truck’s occupant protection did not measure up to its front-seat performance. Shoppers can review the Canyon’s full test breakdown, along with comparable ratings for competing midsize trucks, directly on IIHS’s website before making a purchase decision.
