The Brake Investigation

The Brake Investigation
The Brake Investigation

The National Highway Traffic Safety Administration (NHTSA) launched an investigation into the braking system of 62,000 the model year 2010-2011 CX-9 vehicles. Upon further inspection, Mazda identified a materials issue in the brake booster diaphragms, causing noise, degraded performance, and spongy response from the pedal when initially pressed. The problem was caused by wear of the mold used during its formation, resulting in tears near the outer seal that allowed leakage from one side to another. To resolve this issue, Mazda extended their warranty with details as follows:

  1. Coverage for parts and labor necessary to replace defective components;
  2. A “lifetime” repair option if drivers choose to keep their vehicle;
  3. An enhanced reimbursement policy if drivers had already paid out-of-pocket expenses related to repairs and
  4. Reimbursement on rental cars while repairs are being made or if customers prefer not to drive their vehicles until they can be fixed properly.

FAQs About Mazda Cx-9 Brake Booster Recall

What does a failed brake booster do?

With a failing brake booster, force amplification from one’s foot diminishes. This results in increased effort required to engage the brake pedal. Due to this decreased force on the master cylinder, hydraulic pressure in the brake fluid decreases as well, ultimately making it more challenging to apply brakes effectively.

What is the recall on the Mazda CX 9 2013?

The CX-9 vehicles, manufactured by Mazda North American Operations between October 24, 2006, and December 28, 2013, are being recalled due to potential corrosion of front suspension ball joints caused by water infiltration into the fitting.

Does a Mazda 3 have a brake booster?

The Mazda 3’s power brake booster is integral to the vehicle’s braking system, working in tandem with the brake master cylinder. Utilizing engine vacuum amplifies the force applied when engaging the brakes, resulting in a smoother and more effortless stopping experience for drivers. This innovative feature reduces the effort required to fully depress the brake pedal, allowing maximum braking pressure to be achieved effortlessly. It is a vital element that enhances both safety and efficiency on the road for Mazda 3 owners.
