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.

Our 2007 Cx-7 Mazda developed noise. We received letter from dealership regarding possible need to fix ac compressor. About 10 days later on Sept.5 2010 we took a trip and did not turn on the ac but a loud noise developed and we lost acceleration ability. No warning light ever came on. Our car has about 40,000 miles on it. Towed it to Mazda dealershilp. They said they couldn't tell what was wrong. Several days later they said the turbo had failed and the engine is ruined and would need replacing. They said that the engine had no oil (remember, no warning light) and they found sludge, indicating neglect. We have had oil changes as required. They have not agreed to fix it. We have found numerous other owners of same model and year online on edmunds.com. It seems to be a problem for this particular model and year and the dealers response is to deny honoring warranty due to "sludge". our next move is to take it to the dealership we purchased it from out of town.
I have a 2007 Mazda Cx-7. it is a very beautiful car but also has tons of problems. At 15000 miles it was leaking oil and they replace the engine gaskets. Then later was also leaking oil. Was told by the dealer that it was not. Took it to someone else who said it was leaking from the timing chain. Mazda resealed it. Since then my car doesn't shift properly going up and down hills. My air conditioner is hot and makes a funny sound. My car has loss of power and sound like a diesel. Overall I think that Mazda needs to step up and take care of the problems or they will not get many returning customers! something needs to be done! it was a 35000 dollar car!
My 2007 Cx-7 had been making a noise for a couple of weeks so I had it checked out by two different places and was told by both that the timing chain is about to break. It has 66K miles which seems low to be having this kind of problem. I will be taking it to the Mazda dealership but since I'm over the 60K my warranty has expired.
Mazda 2007 Cx-7 engine seized. Heard a clicking sound for a few seconds at the start-up of the vehicle intermittently and would go away. This went on for a few weeks, but did not occur everytime the car started. Car seized at a traffic light and failed to operate normally, loud clanging noise followed by decrease in speed, could not get the vehicle past 15 mph. Car has 30,000 miles, called dealer since vehicle is still under warranty. Dealer indicates that engine and turbo need to be replaced and has contacted Mazda for warranty verification. No oil in car, and mechanic reports sludge in oil pan. Dealer requested receipts for all oil changes and parts since I performed all maintenance. I have no receipts. From reading the horror stories from similar individuals online with same problem, Mazda will more than likely decline my warranty and claim that I the owner did not properly maintain the vehicle. I have had several past problems with my vehicle since its purchase and have had warranty service work performed on numerous occasions. With all the times that my vehicle was in service, I was not notified of a Mazda service bulletin #01-002/08, which addresses certain VIN # 2007 Cx-7's (mine qualifies) to have a variable valve timing replaced due to numerous engine failures coinciding with the problem that I have experienced. The bulletin indicates that only customers who complain of engine noise will be treated with warranty replacement service. Since I had no inclining of the ongoing issues with the 2007 Cx-7, I am being penalized for having to pay for the engineering defects with the Mazda 2007 Cx-7.
Like tons of other reports online, my 2007 Cx-7 is having a timing chain/vvt actuator failure at around 40000miles. Luckily, after reading the reports online, I told my Mazda dealership about this problem and they are in the process of repairing while timing chain was at its breaking point (that would have resulted in a blown up engine while driving).

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.
