Nissan recalls nearly one million vehicles for airbag problem

Nissan is recalling nearly one million vehicles for a problem with the airbags. The occupant classification system (OCS) may incorrectly think that the passenger seat is empty when it is occupied by an adult, failing to activate the airbag in a collision. Cars affected include the 2013-2014 Leaf, Altima, Pathfinder and Sentra, as well as the 2013 NV200, 2013 JX35, 2014 QX60 and the 2014 Q50.

Video: Track-day fun in the Lexus LFA

As promised, the third installment in our supercar video extravaganza--after the Chevrolet Corvette Z06 and the Porsche GT2 RS--gives you the lowdown on the hyperexotic Lexus LFA and its insane 552-hp V10 powerplant.

Check out the walk-around and some on-track fun, then come back for the VBox lap on Friday.
