I own a Mazda 2008 CX7 sport - purchased new on 11/28/2007. I have 62,500 miles on the vehicle. It was towed to the dealer on 6/22/2010 with loud whining noise and loss of power. Dealer said the turbo is malfunctioned. Over the next week the extended service company for Mazda requested maintenance records. I had the oil changed outside of the dealer some of the time. They looked at this and declined the warranty repairs. I kept calling and they agreed to send out an independent adjuster. He noted a "sludge" build up on the oil return hose bolt to the turbo. They declined my warranty coverage. I am having to pay $2500 to repair. I have been doing research online and this vehicle is having numerous issues with sludge buildup. This comes from the engine running to hot and breaking the oil down to create blockages that ultimately affect the turbo or other internal engine parts. If you look on edmunds website you can see their are others with the same issue. Mazda will not make the recall or assist the consumers. We follow their recommendations on oil change and are getting no assistance. I am afraid that I will have additional issues once this is repaired and they will decline future service. Hat can you do to help? I actually have the dealers printed copy of where they repaired the timing belt tensioner in April at 57K miles. According to the supervisor for customer service at the extended warranty office his computer records show they repaired the serpentine belt for less money that the dealer records I have in hand. What is going on this just does not seem honest. I need help and there are others with the same situation over the last year - some having to spend $7500 + out of pocket to repair their CX7. Please call me for help.
