GMC Sierra 2015 Fatality Profile

Background

The 2015 GMC Sierra fatality profile in this snapshot is built around 180 fatal crashes and 203 occupant fatalities. The data was computed at 2026-07-14 and carries a snapshot date of 2026-05-02.

Within that record, the profile points to several recurring crash circumstances: 90 single-vehicle crashes, 24 alcohol-involved crashes, 21 rollover crashes, and 5 fire crashes. These figures describe the fatal-crash population for this vehicle rather than all crashes involving the model.

Fatal crash picture

The broadest pattern in the file is the prominence of single-vehicle events. Of the 180 fatal crashes, 90 were single-vehicle crashes, listed here as 50.13%. Alcohol involvement appears in 24 fatal crashes, or 13.26%.

Rollover and fire are less common but still notable in a fatality review. The findings list 21 rollover crashes, equal to 11.62%, and 5 fire crashes, equal to 2.9%.

Fatal crash factor	Crashes	Share
Single-vehicle	90	50.13%
Alcohol-involved	24	13.26%
Rollover	21	11.62%
Fire	5	2.9%

Severity outcomes

The file records 203 occupant fatalities across 180 fatal crashes. It also lists deaths per crash at 1.13. In practical terms, the fatality burden in this profile is not confined to isolated incidents; the crash count and the occupant death count both remain substantial in the record.

That said, the findings do not break fatalities out by crash type. The document identifies how many fatal crashes involved rollover, fire, alcohol, or a single vehicle, but it does not say how many occupant fatalities occurred within each of those groups.

What stands out in the narrative

Two features define the profile most clearly. First, single-vehicle crashes account for 90 of the 180 fatal crashes, making them the largest named category in the findings. Second, alcohol involvement appears in 24 fatal crashes, while rollover appears in 21 and fire in 5.

This creates a picture in which the 2015 Sierra’s fatal-crash record is shaped more by roadway-departure or loss-of-control type events captured in the single-vehicle count than by fire-related outcomes. Fire is present in the data, but at 5 crashes and 2.9%, it is a comparatively small part of the fatality profile presented here.

Limitations

This snapshot is narrow by design. It reports fatal crashes and occupant fatalities for the 2015 GMC Sierra, but it does not provide exposure measures, non-fatal crash counts, mileage, trim differences, roadway type, speed, restraint use, or occupant demographics.

It also does not show overlap between categories. A crash could potentially be single-vehicle, alcohol-involved, and a rollover, but the findings do not quantify those intersections. For that reason, the figures are best read as separate descriptors of the same 180 fatal crashes.
