The a/c evaporator tank condensation drain clogs. Ours has clogged twice and the first time the water in the tank would slosh around and hear it when making a left turn. Eventually it ruined the blower motor to the a/c, which had to be replaced. Now 19 months later, we heard the water again and took it in right away and it was clogged again and the blower motor has to be replaced again. This is a design defect. There should be a better drain system. Clearly this is an issue with the Mazda cx-9 model in several years because there are videos of how to unclog the a/c drain.
Takata inflators recall? no incident to report.
Breakbooster when we asked our mechanic to check it and end up after calling Mazda fremont that it is covered by the extended warranty for this. While drivig I thought I loss my break and was not fully working. Was scared . Mazda fremont assisted us and provided us a temporary car to use.
Front lower control arms safety recall 8515g / NHTSA campaign no. 15v-451 :: July 19 2016 went to team Mazda Subaru (6218 cleveland blvd. Nampa id) for recall replacements and was told it would take 2 weeks for parts to be ordered & delivered. August 8th, I called team Mazda after not receiving any call/ notification and was told I would receive a call back. Still no call back (August 9th; three weeks later).
When pressing the brakes at any speed there was a hissing sound and the brakes were hard to press. Regardless of the amount of pressure I applied to the brakes they did not react and it took the vehicle longer to slow down even at very low speeds (5-10 mph) or faster. This came on suddenly and caused me to bring the vehicle into the service department of the the dealership where I purchased it. The Mazda technician inspected the vehicles and completed a diagnostics of the vehicle and discovered that the master cylinder and brake booster have failed and need to be replaced.
The Mazda 2011 cx-9 crossover SUV seems to have a defect in the power transfer unit (ptu). Mazda north american operations issued a letter to Mazda owners informing about a special service program to extend the warranty coverage for the repair of the power transfer unit (ptu) on "certain 2010-2011 cx-9 all-wheel drive vehicles produced from July 28, 2009 through December 2, 2013. " I quote the letter. On March 18, 2015, I began to experience a problem whereby my 2011 cx-9 made a grinding and snapping sound when in reverse mode. This behaviour was followed by a pungent odor in the cabin. I contacted the nearest dealership and tried to get an immediate appointment to examine the vehicle. However the dealership could not accommodate me nor expressed any awareness of the symptoms. Yet, the letter was published since last year. I contacted a local mechanic and had them inspect the vehicle and they diagnosed the problem exactly as described in the letter from Mazda. In fact, the mechanic is aware of this problem with Mazda and Lincoln brand vehicles. Currently, I am having trouble getting immediate assistance from the dealership or Mazda north american operations. I called several times to the dealership and they were unresponsive. Is NHTSA aware of this ptu defect and what was necessary to require a recall/replacement of the ptu 'prior' to inevitable failure as we experienced? thank you.
