“’Do not drive’ recalls are much more rare, but much more dangerous than other recalls,” explained Em Nguyen of CARFAX. She emphasizes that a “do not drive recall” is not a recommendation. CARFAX estimates some 725,000 vehicles on U.S. roads right now are under a “do not drive” recall. “And with that comes more chances of something going wrong.”In Utah, CARFAX estimates there are about 5,800 cars and trucks under “do not drive recalls” that are still being driven.
