“My 2009 CX-7 has a major oil leak at the oil cooler. Upon learning this I turned to my mechanic and the internet only to find out this seems to be a very common issue. This defect is something that is on every Mazda forum and should be made a recall and fixed. This is a very well maintained vehicle that should not have this type of issue at this mileage.”

NHTSA complaint #10553094, filed 2013-11, 78,120 miles

“Around the end of april 2012 I noticed that my Mazda started making a loud noise - comparable to a semi or diesel truck. The noise was constant, regardless of speed, and maintained at the same level as long as the car was on. I took the car to Mazda on may 12th to determine the cause of the noise. Within a few hours of dropping the car off, the dealership called me back and advised that it was the vvt system that was causing the noise and it needed to be fixed. All they needed was my oil change receipts to cover this repair under warranty. …”

“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. …”

“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!”

NHTSA complaint #10482007, filed 2012-10, 60,000 miles

“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. …”
