Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The brake became very stiff and made a hissing sound when applied while driving. I brought my car to an independent mechanic and back to the dealer where I brought the car and they both confirmed that I needed to replace the brake booster. That the hissing sound was leakage.”

NHTSA complaint #11349740, filed 2020-08, 66,000 miles

“My brake pedal became very hard to press down to stop my vehicle. A hissing sound was coming from the pedal. Even at low speeds 20-30 miles per hour I was not sure if my car would stop. I was pressing down on brake pedal has hard as I could. Took it in for repair 5/22 I was told it was the brake booster assembly this was known to be faulty in this model Mazda but to recall was incorporated. Repair cost was $760.00 put of my pocket.”

NHTSA complaint #11098510, filed 2018-05, 99,000 miles

“While driving my 2013 cx9 I noticed the brakes required extreme force to engage and I heard a hissing sound when I engaged my brakes. Since I had the same issue with the brakes on my 2010 model, I immediately contacted the dealership where they are currently repairing the brakes under warranty.”

NHTSA complaint #10595603, filed 2014-06, 21,000 miles

“Brakes pedal on my wife's car became hard when pressed on (regardless of speed) and noticed a hissing noise when applying brakes. The worst and scariest part is that the brakes didn't stop the car and felt as if I was applying the brakes on a car that was not turned on. Luckily we didn't get into any accident and stop driving the car. Had car towed to mechanic who informed me that the brake booster was bad and needed to be replaced. Checking online and this appears to have been an known issue with earlier cx9 cars.”

NHTSA complaint #11222325, filed 2019-06, 70,000 miles

“A truck swerved into my lane and I tried to brake. The pedal didn't immediately depress so I had to serve. Jumped a curb and hit a sign. More than $11,000 of damage. The brake is very difficult to depress quickly.”

NHTSA complaint #10885005, filed 2016-07, 96,000 miles
