' takata recall' it seems after having my car for 4 months I ran into issues. I was driving on a residential street when my car started making a strange whining noise and small plumes or white smoke began to come from the hood, near the pulley systems. I drove home approximately 4 miles away . I went to start it the next day and it won't start it seems to be the alternator.

Was driving and all of a sudden lost power and a howling noise no check engine light came on. Pulled over to see what it was and nothing visible no leaks nothing. Had my wife hit the has and no noise. Stared driving and noise came back and white smoke. Just had an oil change done and next oil change due in about 1000 miles. Drove about 20 MPH to get home check oil and it was ok. The white smoke makes me think the turbo went on my car. I just purchased this car in october of 2015. It's been back to the shop for electric problems with the key and radio that still not resolved. Radio shuts off and beeps that key is not in car.

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.

While on a freeway off-ramp car started to idle irregularly accompanied by white smoke and a loud whining noise. Identified problem as A/C compressor. Turned off air conditioning; smoke and whining seemed to stop, and I was able to drive it the 15 miles to my mechanic.

On 8/31/14 I noticed a rattling noise when I accelerated as well as a whining noise. The noise was intermittent and did not occur all the time, but was a distinct noise coming from underneath the vehicle. I had not had any check engine lights illuminated or any other warning lights. I brought my vehicle into my local mazda dealership and they advised it was the turbo and in order access appropriately they would need to tear down the engine. After reading online there are numerous documented issues with turbos, vvt timing chains and engine issues with mazda cx7. The shop called me back 2 days after I dropped it off and said I would need to replace the turbo & I need a new engine. They also stated since there was oil sludge present that I would be responsible for $9000 costs. I provided the dealership my oil change receipts including the last oil change that was done in june. My car was still within 3000 miles and was not due a oil change, however the owners manual stipulates recommended changes every 7000 miles!! The dealership advised that when I brought it in no oil was in the dipstick and because there was sludge mazda is denying my powertrain warranty (which is still active) due to not maintaining the vehicle. This is absurd, I have maintained my vehicle and mazda is using this as an excuse to not be responsible for a obvious defect in their vehicle!!! There are many documented instances about this same scenario happening with others all over the internet, this issue is a result of a defective turbo and not due to lack of maintenance. Mazda extended turbos and vvt timing chain issues to 7 years because of this same scenario for 2007-2010 mazda cx7s but when I asked about ssp 86 im being told my vehicle does not qualify. I would like to know why mazda can get away with not abiding to their warranty and request this be investigated. Thank you

Vehicle started making a loud whining noise while driving at 55mph. White smoke started pouring out of rear end. We thought the car was on fire. It then wouldn't get over 20mph. Pulled over and called a tow truck.

This mazda cx-7 has been driven by my disabled finance and used for in city driving it's whole life and one day a high pitched whining sound developed and the car was delivered to capitol mazda for an inspection. Upon getting the results we were told that the car had not had regular servicing at the dealer. I agreed as I am an engineer and do most servicing of my families vehicles. They said I had not done the oil changes, but I had done them every 5,000 miles. Every vehicle I have ever owned had more than 200,000 mile on them when I sold them. The current toyota truck I am driving has 205,000 and I have done all of the servicing myself. Mazda wants over $8,000.00 to repair it back to driving condition. This is an outrage. And it doesn't seem to fix the problem. Several forums about this particular vehicle issue show some owners have had more than one turbo installed and then the issue came back. Online I have found literally hundreds of stories just like mine. The turbo in the cx family of vehicles is an issue. Since mazda doesn't want to take responsibility, the government may have to look into a fine and also a recall of all of these potentially dangerous vehicles on our roads.

There was a knocking almost as if the car was a diesel, brought the car to milford mazda in milford ct after purchasing the vehicle a month earlier at bobs in milford ct. The mazda dealer replaced the vvt december 2012 the service engine light goes on and I take it to the local garage and they get a code for camshaft, I bring the car to mazda who tells me upon arrival with out even looking at the vehicle that I need a new engine and it wouldn't be covered under my extended warranty because they are sure there is sludge in the engine, yea same story everyone else gets. I faithfully had my oil changed every 5,0000 miles max as this was drilled in my head growing up from my dad. Approximately some time in march I was driving to work I get this loud whining sound coming from the engine and the car loses all power the turbo went. I have a new turbo installed and still supposedly need another vvt just 2 years after they replaced this part and now there is a humming/whining noise coming from the rear of the car not to mention (2) tie rods are bad. This car is no doubt a piece of crap that I still owe 13k on and mazda corporate will not even return my call. There has to be something that can be done with all the same complaints.
