Water Pump Leak

CarComplaints.com Seal Of This Might Hurt

CarComplaints.com Notes: The only area of real concern for 2012 Mazda CX-9 owners is the brake booster.

In 2014, Mazda extended the warranty on the 2007-2013 CX-9 brake booster to 7 years / 90,000 miles. However this extended warranty has expired for most CX-9 owners, so buyer beware.

This Mazda CX-9 brake booster failure isn't terrible in terms of repair cost — it "only" costs $550 average to fix. However it is a safety issue when the brake booster fails as it increases stopping distance. Owners have reported having to stomp on the brake pedal, & crashes/injuries have been reported due to this CX-9 brake booster defect.

CX-9 3.7L

  • Automatic transmission
  • 94,500 miles

At only 94,500 miles, I took CX-9 into the dealer for a recall job and they found early indication of a coolant leak at the water pump. To replace this $30 part requires engine REMOVAL. Found many people with the same failure between 90,000 and 110,000 miles.
