Notes: The 2007 Mazda CX-7 has numerous reports filed with the NHTSA about engine & A/C problems.

Owners report problems with the 2007 CX-7's Variable Valve Timing (VVT) & timing chain failing, causing major damage to the engine — Mazda uses an interference design so typically the valves are bent & the entire engine needs to be replaced. Mazda dealers typically quote $9,000 for an engine replacement.

There is also a trend of the turbo failing at low mileage.

Finally for the 2007 CX-7 there is a clear pattern of A/C compressor failure at relatively low mileage. Owners report smoke & occasionally the serpentine belt catches fire when the A/C compressor clutch seizes while driving. Mazda extended the A/C warranty to 60,000 miles, however many owners report their A/C compressor failed very soon after the 60k mark.

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.

Air bag light comes on and off randomly with or without passenger in seat. Have had so many issues with this 2007 Cx-7 from 2 different complete A/C system rebuilds in first 2 years, belt tensioner pulley, egr valve codes (had to get egr valve cleaned), coolant temp codes (replaced thermostat & temp sensor) and now air bag random light. I am on a Mazda forum and honestly there should be more recalls on this vehicle due to the volume of complaints in several categories... Mazda responses to just about everything is to replace something for a minimum $500 up to thousands... I am tired of having to deal with Mazda and will never buy another... traded in a 2001 Chevy Tahoe for Cx-7 with 250,000 mi and only had normal maintenance. The Cx-7 was a bad investment for me...

CX-7 4-cyl

  • 101,000 miles
My 2007 Cx-7 started making a loud banging noise when I started it (May 7,2012). I brought it to the dealership to have it checked out and they said it was my timing chain & actuator (vvt) and it would take $1350 to repair. I paid the money and it was fixed in a couple of days. On June 7th,2012 I started to realize that my ac was not working, but had decided to wait a little bit to have it fixed because I was still hurting financially from the last fix a month ago. Than on June 9th, 2012, I went to start my vehicle and it sounded like it was about to explode. I live in the country and the closest dealership is at least 50 miles away. So I brought it to my local repair shop and they told me my turbo is blown. The Mazda dealership wants $80 to diagnose it and $5000 to fix it (that doesn't include my towing fees and the cost of fixing the ac). I've read all of the complaints online and everyone is saying sludge build up and Mazda wants the receipts for all of their oil changes. I have all my receipts for the synthetic oil changes that I have had done to the vehicle on time (not to mention only filling the car with premium gas). Unfortunately, my car is up to 100,000 miles and they only extended the warranty to what...70K" so basically I have a car that I paid $16K for and is completely useless to me only after 100K miles. From what I've researched vvt's are not supposed to go out until what 250K-300K miles" and it seems a bit ridiculous for the turbo to go out after 100K miles....
