My 2007 Mazda Cx-7 starting making a popping noise and began losing power on April 13, 2012. I drove my car to the dealership and was told that the timing chain and turbo charger are bad and need to be replaced. My car has 80,477 miles on it and therefore, nothing is covered under warranty and I cannot produce all oil change receipts. Thus, it is going to costs me $3,000 to get fixed. I am very disappointed in Mazda for not fixing a defect that they are clearly aware of, regardless of the mileage! I never received a recall letter and I have been a loyal Mazda customer, purchasing 5 Mazda's over the last 12 years! I travel with my job so I do put a lot of miles on a vehicle (averaging 2,000 miles per month) but I find it utterly ridiculous that a car has major defects at 80,000 miles! please help and stop Mazda from taking advantage of consumers!

After short duration idol "5-10" minutes car blew heavy white and black smoke out of exhaust followed with a clanking/rattling sound from the rear of car. Three time this happened in a short 4-7 mile drive home. Took it to the dealer and at first the said they could not duplicate the problem but updated the engine and transmission computer program. Then they let the car idol for some time and it blew the smoke and heard the sound. So they decided after calling and reporting the event to the regional manager to replace the turbo. I have looked on-line about these problems and have come across owners that have had their turbos replaced a few times and the problem still exists. When the parts are in and they replace the turbo, I will see if this is a fix. I have very little faith that this will fix the problems this vehicle has. And it has many.
