One of the other key tests to merit the Top Safety Pick+ award is headlight performance. In this case, each gets a "Good" rating to earn the award, but there's a caveat. Only high-end versions of each vehicle have highly rated lights. On the Subaru Ascent, the "Good" headlights are LED units on the Limited and Touring trims, and the Hyundai's are LED units that come with the Limited and Ultimate trims. The lower trim levels of both vehicles come with halogen headlights. The Ascent's halogens were rated "Poor" for not providing enough illumination while also causing glare for oncoming drivers, while the Santa Fe's lights were rated "Marginal," the next highest rating from bottom, for simply not illuminating enough, but they didn't cause glare.
While this doesn't apply to a Top Safety Pick+ rating, the Subaru Ascent has one additional commendation. The IIHS also evaluates how easy it is to access LATCH anchors for mounting child seats in a car, as well as how many there are. In this case, the three-row, family-friendly Subaru received the "Good" rating and a "+" for having extra anchors for more placement flexibility. The two-row Santa Fe just received an "Acceptable" rating in this regard, the second highest rating from IIHS.
