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.

While I was driving in town hwy the A/C system quick working, smoking coming from the hood and I totally lost the power steering on the car.. finally after pulling over on a safe place on the side of the hwy I realized the A/C compressor locked and the clutch fell off and the serpentine belt for the steering was broken as well.. what a mess and dangerous situation.. now de dealer says my car A/C compressor repair isn't covered under the warranty with only 39000 miles on it.. this is ridiculous and dangerous for all the Mazda Cx-7 owners.. please take an action and recall the A/C system on those car before someone get hurt or die buy..
The air compressor went on my vehicle and needed to have it totally replaced. The air conditioning nver really worked all that well anyways with the car never getting very cool.
In January 2012, I received a letter from Mazda Inc that the company was extending the warranty on the timing chain to 70,000 miles. In the letter, it stated that a certified Mazda dealer could inspect the vehicle to determine if the timing chain has a problem. On Feb 24 the vehicle was inspected by a certified Mazda garage and when my husband went to pick it up, they said "it has a slight noise but nothing big.then they asked for all the receipts from the oil changes. Now, we bought the car in March 2009, therefore we would have no receipts for the past year and a half the car was with another owner. We only had 3 receipts B/C my husband routinely change the oil. Now, the other thing was in early February, the vehicle began to not start all the time. It was taken to our local garage and the repair man said it could be a number of things, but since it has the timing chain issue...that could be one of the problems that causes a car not to start. It left me stranded on 3 occasions. So, from February until March 30, my husband argued with Mazda and the dealership that first inspected the vehicle. The deal was Mazda was not going to pay for a new timing chain B/C we couldn't produce oil change receipts and if there was sludge in the motor "this could be why". so on March 30, the Mazda dealership called and said for $180 the gaskets could be pulled to see if there was sludge. Which in all the reports that I read on this website, majority of engines had sludge B/C the motor burns the oil too hot. The other repairs that vehicle had: 2010 -air conditioner compressor (it was recalled) ($900), a new starter ($300), Dec 2011- rt rear wheel bearing ($600), Feb '12- new battery ($100) which didn't need to be replaced B/C it was part of the timing chain problem.so on April 4, we traded the vehicle and bought a 2009 Honda CR-V. my husband and I will never by a Mazda again.
We leased a 2009 Mazda Cx-7 (garaged and highway driven only). There was never a problem. The battery died. We changed the battery. Car started and then died. After one month, it again had been flat bedded by Mazda. They did a check and told me they could not find anything wrong with the electrical system, but they found sludge in the engine compartment. They had a recall on a valve which I never received in the mail. The car only had 17,000 miles on it. After 3 years, Mazda came back and said they would cover under lease or extended warranty, which I had. They said it would cost $9,500 to replace an engine with a 17,000-mile leased car and they would not stand by their product. I want to start a lawsuit on the car as I have had many leases without these problems ever and leased over 10 cars in the last couple of years with no problem.
I bought this used around June 2010 with approx. 16000 mile. I had oil change at the local garage station. They told me that the oil was very thick. So I had it changed again within three month. It was running fine without any indication and all of a sudden I lost the power and engine quit. I had it towed to garage and they told me that it is better we have it checked by dealer as this has warranty. Mazda dealer looked in to this and told me that the turbo engine is ruined due to gunk in the oil. They asked me for oil change record. I only had since I had it. I could not get any previous record. Mazda and dealer told me that the warranty is void due to negligence to maintain. They will not cover under warranty. I can not believe this. This car has only 35K mile and no indication and Mazda do not provide any kind of warranty assistance. Anyone else had the same issue with Mazda Cx-7? I think this is something to do with turbo.

I own a 2009 Mazda cx 7 turbo. The vehicle has had it's proper oil changes by a service garage not a "quick lube" place. The oil was castrol gtx 5W-30W, with from oil filter.the longest interval between oil changes was 6000 miles and the shortest 4000 miles. The vehicle now has 45,664 miles on it and the wife complained about a high pitched noise and lack of performance. Brought to the Mazda dealer, the dealer said the turbo went and that Mazda will not cover it under warranty (60,000 warranty on drive train and turbo) because of engine sludge !! are you kidding me...engine sludge, the proper oil viscosity was used at proper interval (Mazda says 7500 between oil changes). No signs of over heating, high engine temps, the vehicle is driven to work and back (4 miles away) 2X's per day 6 days a week. Sounds to me like engine oil is not getting up to temp. And this is causing the sludge, Mazda does not state this anywhere any time in their manual. I found this out only after researching on line....anyone else having issues with their Mazda "??" I've owned turbos before and never had issues. My vehicle gets it's oil change by the same station and this Nissan has 190,000 miles on it with no problems and no sludge !!!
My wife and I purchased a 2007 Mazda Cx-7 from lithia Mazda in fresno, ca. It was a brand new vehicle and within the first 26,000 miles, the air conditioning compressor went out. This was covered under the factory warranty and replaced. Now my the same vehicle has 65,000 miles on it and the compressor went out again. I have been told by the dealership that they will replace the unit (for $1,800) and warranty it for 3 years or 50,000 miles. I fail to comprehend why this is not already covered under the same warranty.
