I took my 2009 mazda cx-7 (108,000 miles) in to the dealership for an oil change and to see why the check engine light had come on. I was informed the turbo needed to be replaced and was advised that the car was unsafe to drive and that I needed to get a new car immediately. The dealership was hesitant to let me leave in the car as it could stop working at any time and because I do a significant amount of highway driving this is particularly alarming. No remedy was offered and I was told it wasn't worth repairing. This is a known issue with the cx-7 and a danger to the driver and other drivers around when the cars stop working due to the issues with the turbo. A recall needs to be issued if so many people are having this issue with serious safety concerns.

While driving down the interstate, vehicle lost much of it's acceleration, and began making a loud whining noise. Pulled off the highway and investigated the noise. It was a loud whining that only occurred in neutral and park over 2500 RPM and with any acceleration while in gear. Also noted yellow foamy oil on the dipstick which was 4.5 quarts low being very close to time to get a change. Towed to the shop to discover that the vehicle is burning oil and the turbo had gone bad. Mechanic suspects that the turbo going bad is what was most likely burning oil and retaining water in the crankcase.

Starting hearing a noise initially--not sure where it was coming from but thought it was internal to the engine. Took it to the dealer for inspection and they verified that the front of the engine would have to be removed to replace the defective part. I can not remember the part name but it was clear from the dealer rep that my car was one of many they have replaced. I spent $1244.00 in repairs on my vehicle that the mazda dealership acknowledged was a factory defect on my car and many others. Just not right

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.

While I was driving in town hwy the A/C system quick working , smoking coming from the hood and I totally lost the power steering on the car.. Finally after pulling over on a safe place on the side of the hwy I realized the A/C compressor locked and the clutch fell off and the serpentine belt for the steering was broken as well.. What a mess and dangerous situation.. Now de dealer says my car A/C compressor repair isn't covered under the warranty with only 39000 miles on it.. This is ridiculous and dangerous for all the mazda cx-7 owners .. Please take an action and recall the A/C system on those car before someone get hurt or die buy..

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.
