Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2012-2014 Prius V vehicles manufactured August 22, 2011, to June 30, 2014.

The 2012 model has about half as many complaints as this one. The 2014 model has about 1.5 times as many complaints as this one. These figures reflect raw complaint counts, not failure rates. Higher-selling model years naturally receive more complaints.
