CarComplaints.com 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.

While driving, heard a noise coming from the passenger side, some smell coming from that direction as well. Lost power to the vehicle, turned off the road and notice that there was smoke coming from the A/C compressor.
Was returning to California from Arizona when car started making an awful noise. I suspected it was the A/C compressor as I had read about their failures online. I had just passed the 60,000 mile extended coverage period, however my Mazda dealer was able to get Mazda to cover 95% of the charges. I was not happy that I had to pay anything at all, but I feel fortunate that Mazda threw me a bone. Others have not been so lucky. Mazda should compensate them.

My wife and I purchased a 2007 Mazda Cx-7 a few years ago, and over the last three months it has been in the shop with multiple problems. From an oil leak, to a bad compressor, then the timing chain gone bad and now another problem with the egr. The car has a little over 38K miles and to me it seems very odd for a car being this young in miles, to have major problems such as these. After going back and forth with the Mazda corporate office, they first agreed to pay for the parts for my latest problems since I'm now out of warranty. I was fine with that until I found out the labor was over $500 to fix this problem. When I call the corporate office to try to discuss splitting the labor costs, their supervisor contacted me back with an attitude like I did something wrong and decided they were now not going to help at all. That is just poor customer service behind a vehicle that was not ready to be put on our us roadways. In my opinion, this car should be recalled. After reviewing some of the forums, many others agree with my displeasure in the problems with the Mazda Cx-7--check this linktownhall-talk.edmunds.com/direct/view/.F0E5B59/110. thank you.
I just got a Mazda cx 7 4 months ago. The A/C system is fried. The factory warranty was no good and I have to pay$1900. Please I am read these articles and do not buy.
I have a Mazda Cx-7 2007. In the last 6 months I had to replace ac condenser twice. It locked up and started smoking. And the car was undriveable. Now they have 300 back orders for this part before I can fix my car.
I am the owner of a 2007 Mazda Cx-7....... about 3 days ago the A/C stopped working and the car only has 40,000 miles on it..... I did a little research and apparently the A/C system in the 2007 Mazda Cx-7 is not exactly up to par because the following year the A/C system was completely re-done on all 2008 Mazda Cx-7..... now im stuck here in blazing hot Texas with a vehicle that is barely 2 years old and I cant afford a new A/C compressor...... also I am looking forward to my car breaking down due to the fact that the compressor has been known to snap belts...
March 09 for the "umpteenth" time the check engine light came on; took 2007 Mazda Cx-7 in to dealership to have the " code " checked; this time (as multiple items were repaired or replaced while still under the 36,000 mile warranty) the code read "oxygen sensor" & I reported that I would need my A/C checked because it sounded and smelled funny plus it didn't always cool; they deferred the A/C, "didn't need any repairs, seemed fine" according to dealership; they replaced the O2 sensor at the cost of >$500 (this is a "common problem" with 2007 CX7/ checked online after the repair and $$$ cost); now July 19, 2009/ had driven car roundtrip 25 miles approx./ noticed smoke coming from under hood (no dash panel light/ or other indicator as to a problem)/ opened hood and smelled something burning plus lots of thick smoke; right side of front quarter panel & hood extremely hot to the touch (leaned in against it to look under hood and got burned (like touching a hot lightbulb or pot of coffee); didn't see any flames, but continued to smell smoke; car is currently outside with hood open, plus windows and sunroof open to allow the smoke that came into the cabin out; researched problem online(after learning from expensive repair March 2009) & saw all the reports re: Smoke damage/ locked-up A/C compressor/ melted wiring to other engine parts/ paint damage; will be taking CX7 in to dealership for diagnostics in the am(from online complaints I get that the repair bill will probably be >$1200); why are almost all of the 2007 Mazda Cx-7 owners having the exact same problems and repairs & still no recall; my car "almost caught fire" because of a "known problem by Mazda" and still no recall; if I had driven any longer/farther my car probably would have caught fire; please do something now, before someone gets hurt or killed because of these "known" problems. Unknown property damage amount at this time (too be determined by dealership mechanics). Thanks for your assistance.

Mazda CX7 2007- 21,000 mile. Air conditioner seized there by shredding serpentine belt, loss of power steering, alternator. Repaired under warranty. Then 1 week later after about 900 miles the pulley off crankcase (harmonic balance) actually fell off ( found inside wheel well fender). Serpentine belt now not spinning, loss of power steering again and engine over heating again. Second repair in progress now(06-22-09).
The contact owns a 2007 Mazda Cx-7. the contact stated that the air conditioner does not work. The vehicle was taken to a dealer and they stated that the air pressure was burned out, which was an ongoing issue with this type of vehicle. The dealer will repair the vehicle at the contact's expense because the warranty was expired. The failure mileage was 36,900 and current mileage was 37,000.
I bought a brand new 2007 Mazda CX7. In Jan. Of 2008, my A/C stopped working and smoke was pouring out of the engine compartment. After having it towed to the Mazda dealership, we were told the A/C compressor was fried. It was still under warranty at that point with approx. 25,000 miles. Around this time we had to have all four tires replaced because they were bald. Now it is May 2009, and once again, the A/C stopped working, the car is no longer under warranty, we took it to the dealership, they told us it was the compressor again, that the part had to be ordered. They disconnected the compressor and said it was safe to drive. The next day while driving the car smoke was pouring out of the engine compartment, after pulling off of the road we tried to re start the car, that is when the belt snapped, and the car is no longer drivable. And the tires are bald again one year later.
