“Brakes prematurely failed after feeling numb and squishy. Upon diagnostic by a local mechanic, it was determined that the brake master cylinder had a leak. In addition, the ABS, traction control and emergency brake lights came on when the symptoms were present. Estimated cost of repair $1250.”
NHTSA complaint #10763179, filed 2015-09, 52,000 miles“We own a 2011 Mazda cx7 and a 2012 Mazda cx9, the motors in the drivers and passenger side windows of both cars when out within a 6 month period of time. The warrant on the cars were out at 36k miles and in 2014. The motors both stopped working past this period time but have read this has happened on these same vehicles. The windows go down but start making a loud clicking sound and will not go back up with out holding you hand on it, creating a very dangerous situation with small children.”
