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.

About These NHTSA Complaints:
This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Timing chain stretched and variable valve timing, and throttle went out. This is the 2nd time that the timing chain has been stretched out on this vehicle. The first incident was at around 64000 miles. The 2nd incident was at 124966 miles. Mazda extended the warranty on the timing to 70,000 miles on January 12. However, I did not get that letter and it happened after I had already gotten the problem repaired under a separate warranty.
This vehicle has caused me nothing but problems! I have had it for 3 years and it has been in the shop 4 times and this last time is the transmission at 70,000 miles! this is ridiculous...Mazda needs to clean up it's act. Customers should not have charges like this early on in the life of a vehicle. The vehicle is gorgeous but perhaps they should have spent a little more time putting it together as it doesn't matter for eye appealing it is when it doesn't run!
I own a 2007 Mazda CX7. Since I bought the car, at 29K miles I had to have the fuel tank replaced. At around 34K had to have the turbo looked at because of black smoke blowing on my bumper, Mazda replaced the pipes. My pipes were still smoking, had to take off work, take car in again because of black smoke, Mazda tried replacing rings in turbo, still blowin bluish white smoke, now getting turbo replaced. I had the air compressor replaced a about a month ago. Now I have a ticking noise coming from engine and I'm scared the timing chain will break soon. Mazda needs to replace the timing chains on these models. I think Mazda should do the right thing an recall this model, yr before someone gets hurt or breaks down in the middle of nowhere with kids in the car.
For quite awhile I had been hearing a "ticking" noise with my 2007 Mazda Cx-7..brought it to the dealership in lafayette, la. To have it checked out. They checked it out, updated recalls in affect, stated they found nothing. Continued to hear it off and on, had my oil changed regularly. On July 10, 2010 my car broke down (4 yrs old, 33,000 miles) had it towed to dealer in beaumont, close to where it had broken down. The service dept. Asked for my service records after it was determined that problem was with the engine.. did not have every receipt due to dealer in area closing with no records there, but provide the last few.. after taking an "image" and sending it to Mazda, it was determined they would not honor the warranty because I had excessive "sludge" and wanted me to pay full cost of a new engine/motor. No one wanted to listen to me..I do remember that when my oil was changed, the mechanic had told me in the past that it seemed to have "sludge", but that was only between 3,000 miles. I had taken care of my car, and they were telling that it had "poor maintenance" and would not honor the warranty!
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.
