2007 Mazda CX-9 Owner Comments

problem #3

  • 99,500 miles


Back in 2011 (my Mazda Cx-9 was only 4 yo), I was driving down the turnpike at 65 mph when my car began to stutter, it would not accelerate and it came to an idle. Thankfully I was near the shoulder of the road so I was able to pull over. South motors Mazda dealership stated the computer (PCM) was fried. It was replaced under warranty. Current day: 2016. My car began having the same symptoms last week when driving 15 mph in a residential area. My car currently has approximately 99,500 miles. Had my car towed to dealership. Ocean Mazda stated the PCM and 3 coils are fried again. Upon reading consumer reviews on 2007 Mazda Cx-9, it seems this is a common issue. I am livid that this issue has not been addressed as a recall as there is obviously a defect in either the coils misfiring or Mazda's pcms are defective. I will be discussing this issue with my dealership today in attempt to not pay over $1900 parts and labor as quoted by ocean Mazda.

Was driving on interstate at night. Engine light came on and car immediately drove as if it were not operating on all cylinders. Took it to dealership and it had multiple misfire codes, 301, 351, 352, 354. I researched and found multiple complaints filed on-line regarding the exact misfire codes I experienced and PCM issues in this particular year, make and model. This problem is way too expensive to fix on a personal level. If Mazda is aware that this has been an issue, they need to remedy it. I do not believe I need to personally pay for a PCM when this appears to be a common problem in this make and model. I believe Mazda is very aware of this problem, and they need to remedy it and replace the PCM.

While driving on the williamsburg bridge there was a slight incline during this time the vehicle was trying to accelerate and that's when it started loosing power and started misfiring. Fortunately, this happened very early in the morning and there were no vehicles except mine. When I got to the other side of the bridge I got off the expressway immediately.
