Notes: The 2010 Mazda CX-7 appears to share the same engine defects as the three previous model years: VVT/timing chain failure & turbo failure. The timing chain failure is especially bad with many cars requiring an engine replacement ($9,000+).

In 2011, Mazda began a "Special Service Program" that extended the warranty to 7 years/70,000 miles covering excessive timing chain noise — an early sign of timing chain failure. However coverage under the program requires perfect documentation of all required maintenance with other stipulations. Buyer beware.

problem #3

  • 42,700 miles


On 4/21/2016 around 1:15pm, I was heading East on I-694 at about 65 mph. Suddenly, the tire low pressure indicator light up on the dashboard with three warning chimes. I travelled for another 5-6 miles and the tire noise became much more noticeable in the back. I was in the left lane of the 3 lane interstate and two more lanes on the right to exit mn highway 252. With no easy access to the right shoulder and heavy traffic, I pulled off onto the left shoulder, put on the emergency hazard flashers. Upon exiting the car, I noticed my left rear tire has blown out, with a one foot gash on its sidewall, totally flat, smoke came off from the inside, and the TPMS was missing from the wheel opening. Waited for 45 minutes for aaa to arrive and put on the emergency spare tire. Subsequently, limbed my way for 2 more miles to exit at hwy 65 and took local streets home. The local repair shop diagnosed the tire blowout as a TPMS hex nut failure due to corrosion. Also found out that the front left TPMS hex nut has split in halves due to corrosion as well. It could have been a real tragic accident with injuries or even fatalities. Sudden failures of TPMS units, especially at high speed driving, are significant safety risks that should be remedied through recalls and awareness training to the public.

In March 2016, two of the nuts securing the tire pressure sensors cracked. One sensor loosened causing the tire to lose air and go completely flat. Upon inspection of the remaining three sensors, mechanics found another cracked nut on a pressure sensor. It was not possible to replace the nut. Corrosion on the tire pressure sensors corroded to much to allow nuts to be replaced. In the end, two tire pressure sensors needed to be replaced for corrosion on the exposed threads and corroded/cracked nuts.

While on interstate the tire pressure sensor illuminated. Husband checked all tires and discovered that one of the valve stems was broken. The outside was corroded. The slightest pressure on it was releasing air at a rapid rate. We had only just purchased the car a week before. How this was not caught by the service department at the dealership is beyond me. The dealership replaced the stem, but we were told that this is a common problem. Really" then why aren't there any recalls on this" after reading the other numerous complaints about our model, I am becoming increasingly nervous over our hasty purchase. Research is key in choosing a vehicle.
