NHTSA Complaint #11487622 — 2011 MAZDA CX-9

Braking trouble recent in weeks in 2011 Mazda CX-9 vehicle. Had mechanic (Euro Motorsports in Chagrin Falls OH) check it out. Turned out to be a faulty Brake Booster. Mechanic test drove car; braking failed and he almost rear-ended another vehicle. He found on line a Mazda service notice dating from April 4, 2014 called SSP93. Mazda issued an extended warranty of 7 years or 90,000 miles, whichever came first, to have defective part replaced by an improved part. But we were never informed by Mazda of Bedford, where we bought the vehicle. Currently, our vehicle has about 83,000 miles. Never knew there was a problem until recent trouble with the braking. There are thousands of CX-5, Cx-7, and Cx-9 vehicles in operation in U.S. right now; probably many owners have no idea there is a brake defect in their vehicles that could cause a serious accident, potentially fatal. Mazda should have done a recall in 2014, not an extended warranty. Although Brake Boosters are supposedly good for at least 150,000 miles of driving, our brake failure at around 83,000 miles proves otherwise. NHTSA should order Mazda to recall all vehicles with the defective brake part and replace them at Mazda's expense, probably hundreds of dollars each time. We do not want to have our brake booster replaced by our regular Euro Motosports mechanics because a recall must typically be repaired by the dealer. We already filed a complaint with State of Ohio Attorney General's office, but their people say the complaint must first go through BBB. No urgency on their part at all, even when informed potentially fatal flaw in the brakes. To avoid dangerous accidents, NHTSA should act more swiftly. Thanks.
