The National Highway Safety and Transportation Authority has recalled all Mitsubishi cars from model years 2010 through 2014 due to a failure that can occur with the brake vacuum pump.
The cars in the recall were built between September, 2009 and March 25, 2014.
Mitsubishi will reprogram the software and/or replace the pump itself.
