CarComplaints.com Notes: The 2009 Mazda CX-7 appears to share the same engine & A/C defects as the two previous model years: VVT/timing chain failure, turbo failure, & the A/C compressor clutch seizing. 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 turbocharger oil leaks & 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.

My complaint; in 3/18/2010 at 2:00pm while I was driving the radio display blanked out and the radio stopped working all together. Traction control system (tcs) was blinking and the electronic stability control stayed on. Gauge needles were bouncing. I stopped the vehicle and turned it on and off three times then everything came back on. Then later in the day 3/18/2010 at 7:00 pm the radio display and the radio stopped working all together. This time I just kept pressing the on and off button a couple times this did not work but then the radio just came on by itself while I was driving. I took the car to the dealer on 3/19/2010 the results as the dealer notice says: Unable to duplicate. Could not find any poor connections to have caused the problem. During test drive. Normal operation observed. Pulled codes, two were found for high voltage. No freeze data available. Called tech-line and no known issues for these symptoms or codes. Suggest inspection of PCM/BCM/fuse block connections and alternator. Inspect alternator, normal output, at 14V. All connections good. No corrosion found. No leaks found in the driver kick panel, or loose connections. Normal operation and condition at this time.
