general problems of the 2009 Mazda CX-7

The Mazda has multiple issues with turbo booster functioning and malfunctioning causing air pollution issues with billowing white smoke fr tailpipe, Mazda does not warranty this by ongoing issues with some repairs having to be done as early as 60000 miles,. My car is less than 100000 miles with extensive repair required to resolve issue, repairs as expensive as 3000 dollars. The smoke is so thick is impairs the vision of cars that maybe behind vehicles with this problem. This issue needs to be reviewed and resolved, car owners should be made aware when purchasing these Mazda of this heavily unreliable important part of the vehicle to make the decision beforehand if they will be responsible for these expensive repairs should they occur.

Turbo leak causing lack of power. This problem said to cost 2300 dollars and still making payments. The mechanic said it can cause a fire. It is all over internet that this is a problem for most owners. Why. I recall?.

Starting hearing a noise initially--not sure where it was coming from but thought it was internal to the engine. Took it to the dealer for inspection and they verified that the front of the engine would have to be removed to replace the defective part. I can not remember the part name but it was clear from the dealer rep that my car was one of many they have replaced. I spent $1244. 00 in repairs on my vehicle that the Mazda dealership acknowledged was a factory defect on my car and many others. Just not right.

Apparently the design of the turbo and the engine creates hot spots in the engine, especially in the turbo. These hot spot create sludge build up which eventually effects the performance and reliability of the engine. Research on the internet shows this to be a problem for a considerable amount of owners of this vehicle. Mazda has refused to correct these problems under their warranty. Also lacking by Mazda, since it is apparently a major cause of large build-ups of sludge, is the necessity to idle the engine for three minutes prior to turning off. This was never explained to us when the vehicle was purchased.

As I pulled out of my parking lot at work I lost power so I drove the car to the dealer. They called and told me the turbo was bad due to being clogged with sludge. And, that due to that sludge the entire engine would have to be replaced at a cost of $8,900. I've only owned the car 9 months, have receipts for multiple oil changes, and had an extended warranty - however, the extended warranty company (ameriplus) states that because the problem was caused by sludge, I'm not covered. I've researched and discovered that this is a huge problem with this vehicle, please help me!.

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.

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 rouined 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 delaler told me that the warranty is void due to neglence 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.

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.
