In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sierra Limited are reminded to check the back seat if they opened the rear door before starting out. The Tundra doesn’t offer a back seat reminder.
Full-time four-wheel drive is optional on the Sierra Limited. Full-time four-wheel drive gives added traction for safety in all conditions, not just off-road, like the only system available on the Tundra.
When descending a steep, off-road slope, the Sierra Limited’s optional Hill Descent Control allows you to creep down safely. The Tundra doesn’t offer Hill Descent Control.
The Sierra Limited SLT/AT4/Denali offers an optional Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Tundra only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the Sierra Limited and the Tundra have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the GMC Sierra Limited Crew Cab is safer than the Tundra Double Cab:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Sierra Limited is .7% to 1.9% less likely to roll over than the Tundra.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Sierra Limited the rating of “Top Pick” for 2017, a rating granted to only 212 vehicles tested by the IIHS. The Tundra was not even a “Top Pick” for 2016.
