Engine Failure problems of the 2008 Mazda CX-7

While traveling at 45mph, experienced sudden loss of power. Cel came on and trouble p3001 was the code display on handheld reader. Car is out of warranty, dealer states several components within engine have failed and Mazda has no responsibility over failures since I do not have an extended warranty. I have researched the problem production years 2007 and 2008 are plagued with premature engine failure.

On September 22, 2011 our 2008 Mazda Cx-7 experienced a complete engine failure. This failure occurred without any warning while driving on a freeway: the engine had not previously experienced any problems or made any unusual noises, no indicator lights had signaled a problem, and we had made oil and oil filter changes in accordance with the maintenance schedule. The failure created an extremely dangerous situation, as the car lost power and this meant that several critical functions, most notably, the steering, were severely compromised; the driver only just managed to bring the car to a safe stop. The Mazda service center examined the engine of the car on September 26 and reported that the piston in the number 2 cylinder had failed damaging the engine beyond repair. The service manager verified our maintenance records and indicated that the engine was free of sludge or other build up.

I purchased a Mazda Cx-7 new in 2008. I recently experience total engine failure while riding on the highway with my daughter. The Mazda dealer looked at the vehicle and contacted the warranty company and Mazda on this issue, Mazda stated there was "sludge" in the engine and that was not covered by the warranty. They stated this must've been caused by owner maintenance, however, I have maintained the car as stated in the manual. The company stated we need to produce copies of all of our oil changes since purchase of the vehicle and the dates/mileage at the oil change. We did not have this information, however many complainants who have produced the oil change history are still denied warranty claims. This issue of sludge is not only causes by the owner, but also caused by manufactured defects as in the Toyota case. Many other Mazda owners and mechanics have stated the turbo charging in the new Mazda Cx-7 has started to "cook" the oil too fast and this causes the sludge in the engine, however Mazda will not own up to this defect and honor the warranty and this vehicle. There have also been sited issues of the timing chain causing engine failure however Mazda would not look at any other issues. My vehicle is still under the 60,000 mile warranty and a defect of the engine going out should be covered. Mazda is illegally making the allegation about the owners of the vehicle causing the engine failure in a car only two years old, only to not be responsible for a problem it has caused. Please help me and other Mazda owners correct this issue. There are currently multiple complaints against Mazda and many vehicle owners such as myself are without a vehicle while in litigation with this issue. The repairs would cost over $7000. I have also copied and pasted the forum in which over 100 people have discussed this exact trend in their vehicles and Mazda being less than willing to further assist with this issue. . Read more...
