The National Highway Traffic Safety Administration (NHTSA) has opened an investigation on the 2010-2011 Mazda CX-9 large crossover for a possible brake issue.
According to NHTSA, a preliminary evaluation into the CX-9 has begun after receiving seven consumer complaints of unexpected loss of power-assisted braking. The evaluation will be the first step in determining whether or not Mazda will have to issue out a recall to address a safety problem.
