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.

While traveling on the turnpike at 70 mph at night my entire dash board, including speedometer, warning lights and temperature controls and head lights and back lights went blank and dark. Pulled off road and shut engine off. Was going to call road service, but turned engine on and everything came on. Drove another 15 minutes and the entire dashboard and head lights went out. Pulled off road and shut off engine and turned it on again and all was working again. Got home safely without more problems. Same problems with dashboard during daylight thereafter. Took car to dealer asap where all my service has been done since car bought new. Dealer had car 4 days and could not duplicate problem until the third day when one of the master technicians drove the car 30 miles to his home. This time I was told the entire dashboard went black at night. Was told by dealer that they think they fixed the problem by some computer adjustment to a sensor. Really got no details of what was wrong and will it happen again. All of these problems started a few days after dealer had car for the front lower control arms safety recall 851G and other routine service such as oil change, wheel alignment, multi point inspection and battery replacement to new battery. Also tire rotation. Overall a very dangerous situation that could have caused an accident with serious injuries or death.
The contact owns a 2012 Mazda CX9. The contact stated that the headlights would provide more than 15 feet of illumination unless the highbeams were turned on. The contact had taken the vehicle to the dealer twice and the contact was told there was nothing wrong with the headlights. The VIN was not available. The failure mileage was 10 and the current mileage was 8,100.
Both my tail lights form condensation. I contacted both the dealer and the corporation several times. The corporation maintains this is a normal occurrence that comes and goes depending on the weather conditions. Consequently they don't consider this a warranty issue, as a result they won't do anything to remedy the problem. The service manager from the dealership informed me that they use to replace the faulty unit until Mazda refused to reimburse them. Their excuse seems to be absurd considering the unit should be sealed.
