For the first time since the Insurance Institute for Highway Safety began giving out Top Safety Pick awards two years ago, a truck, Toyota Tundra, has received the designation. But Consumer Reports points out that its electronic stability control system, a requirement for the award, does not work when four-wheel-drive is engaged. IIHS says that it was not aware of this when it tested the Tundra, but the truck has ESC and so the award stays.
Background
To win Top Safety Pick rating, vehicle must receive score of good in front, side, rear-impact tests
Beginning in 2006, ESC must be standard or available as option for vehicle to qualify as Top Safety Pick
