general problems of the 2009 Mazda CX-7

This Mazda Cx-7 has been driven by my disabled fiance and used for in city driving it's whole life and one day a high pitched whining sound developed and the car was delivered to capitol Mazda for an inspection. Upon getting the results we were told that the car had not had regular servicing at the dealer. I agreed as I am an engineer and do most servicing of my families vehicles. They said I had not done the oil changes, but I had done them every 5,000 miles. Every vehicle I have ever owned had more than 200,000 mile on them when I sold them. The current Toyota truck I am driving has 205,000 and I have done all of the servicing myself. Mazda wants over $8,000. 00 to repair it back to driving condition. This is an outrage. And it doesn't seem to fix the problem. Several forums about this particular vehicle issue show some owners have had more than one turbo installed and then the issue came back. Online I have found literally hundreds of stories just like mine. The turbo in the cx family of vehicles is an issue. Since Mazda doesn't want to take responsibility, the government may have to look into a fine and also a recall of all of these potentially dangerous vehicles on our roads.

I was driving on a highway. I heard a high pitched squealing sound then smoke started blowing out of my car. I could not see, and the other drivers behind me lost visability too. In the middle of this blinding smoke, surrounded by huge trucks, I lost aceleration. My instrumentation panel did not have any warning lights on. I was driving blind. I pulled off the highway as quickly as possible, and had my car towed to a dealership. The dealership said my turbo blew out, (which I guess sucked all the oil out of the car) I need a vvt valve and the timing chain is stretched. On a car with 57,000 miles! in checking on line, I found this has been a problem with the Cx-7 for 6 years and they are no longer making this model. I see that Mazda deals with these problems by stating the owner did not maintain the car properly, when in actuality, there is a serious problem with the turbo system and how the oil cools it. There is also a problem with "sludge buildup". I believe Mazda has been successfully avoiding a recall. But these issues are a real safety concern. I am very lucky that there was no accident as a result of this incident. These issues can be dangerous. When everything blew on my car, no one could see the road.
