CarComplaints.com Notes: The 2008 Mazda CX-7 has numerous reports filed with the NHTSA about engine & A/C problems, continuing these defect trends from the 2007 model year.

Owners report problems with the 2008 CX-7's Variable Valve Timing (VVT) & timing chain failing, causing major damage to the engine — Mazda uses an interference design so typically the valves are bent & the entire engine needs to be replaced. Mazda dealers typically quote $9,000 for an engine replacement.

There is also a trend of the turbo failing at low mileage.

Finally for the 2008 CX-7 there is a clear pattern of A/C compressor failure at relatively low mileage. Owners report smoke & occasionally the serpentine belt catches fire when the A/C compressor clutch seizes while driving. Mazda extended the A/C warranty to 60,000 miles, however many owners report their A/C compressor failed very soon after the 60k mark.

In 2011, Mazda began a "Special Service Program" that extended the warranty to 7 years/70,000 miles covering turbocharger oil leaks & excessive timing chain noise — an early sign of timing chain failure. However coverage under the program requires perfect documentation of all required maintenance with other stipulations. Buyer beware.

There was blue smoke in 2013 and the engine oil had been burned to nearly empty. It was fixed with my own pocket but in happen again. Fyi, the first time it happened at almost 40,000 miles and right now is 62000miles. Right now there is a problem of the power steering pump which may out of control when it makes turn. I read anticle say that Mazda will recall cx 7 including year 2008. When I call them today they said no such kind of recall. I read a lots of article complaining Mazda Cx-7 regarding of these two issue. Hope your department can follow up to protect consumer. Also when the car runs in highway of fast enough there's no smoke but when it runs slow the smoke come out tremendously. Thanks.

Took car to Mazda for airbag recall, replaced airbag but Mazda tells me the actual sensor that tells the airbag to deploy does not work and its my responsibility to fix it. Prior to the recall the sensor did not come up on the dash after the recall I now have a light on my dash and Mazda is telling me its $700 to replace fix and part and labor. Electrical car shorts out all the time, windows, engine, lights work one day not the next when doors open. Car stalls out when driving and system reboots. Other issue is I have spent 7 thousand dollars in repairs on this car. I have black smoke coming out of the tail pipes, ive replaced thousands of dollars in parts. Engine light wont go off. I took it finally to auto zone for a free engine diagnosis to get a print out and now the emissions valves are showing faulty. Its burning 2 quarts of oil about every couple of weeks/monthly basis. Ive replaced motor mounts, coolant/oil parts, air compressor, headlights, bumber, wiper blades, electrical control panels, rocker arms, spoilers that have cracked with weather, the car still needs another motor mount, I now have a knock in the engine like its the lifters and I still have another year on this 5 year loan on this car. I have to keep rolling payments to the back of the loan to keep up with the repairs. Its very frustrating. Ive never had this many problems with any car I have purchased ever!!! even the parts department at Mazda has said what do you expect you purchased a plastic car on wheels. Is there any other people experiencing problems besides myself?

After bringing to Mazda for takata inflator recall, and lower rocker arms recall, I was told my timing chain should be replaced at a cost of $1300 plus tax!!! a Mazda tech. Said he knew for sure that was the issue just from listening to the noise. My how knowledgeable for a guess. I started researching this, and see that a class action suit was filed in 2012 regarding this issue, and it went no further. I would like to know if I can get further information regarding this issue and if Mazda will pick up this bill. I see a huge amount of folks have complained about this issue and the vvt also, and Mazda has done nothing. I would like to pursue this issue further. Can you help, or direct me on how to do so" I have taken very good care of this vehicle that I have had from new and now all of a sudden it needs a $1300 plus repair" I am dissapionted in Mazda after reading the complaints, the danger this issue could cause, and the fact they dont care.

There are several recalls on this vehicle including air bags. We have made several attempts over the years to get any of these done with zero success. The dealership just keeps telling us to come back. Our air bag light comes on and goes out all the time. The lights fill with water after washing or if it rain causing the headlights to short out and blow the bulbs. The engine rattles everytime you crank the car and then goes away. We have changed the oil regularly and it still does it.

Mazda Cx-7 recall 9716H. Rcvd recall notice in 10/2016 but no further notices & told in notice that parts were not available to correct the dangerous recall. Had no idea how disastrous this problem could be. Driving my Cx-7 on old willets path, smithtown, NY on 2/3/17 @ approx. 6:30pm with my 4 children in the car, traveling less than 35 mph when the right wheel came off the axle of the car. The wheel was the right side passenger side of car. The car then began to turn into oncoming traffic as a result of losing control of the car. Cars had to move out of my way as it was almost out of control. I feared for the life of myself and my 4 kids in the car. Thankfully I was able to luckily gain control of the car due to my 30+ yrs experience as a driver and force the car onto the shoulder of the right side of the road, sliding into dirt. The car skidded approx 75 feet on pavement. (photos attached) the cause of the accident was diagnosed by my mechanic as the ball joint and lower control arm of the car completely snapping/ breaking caused by erosion/corrosion, which is exactly what the recall is for. Car was towed as was not drivable. The tire cause damage to the axle wheel, and other parts of the car and engine as described by smith haven Mazda, where car is currently being repaired. Had I been traveling at a higher rate of speed, this could have been a deadly matter and myself and 4 children could have been killed. I am so upset that Mazda did not immediately notify their customers to completely stop using these cars due to the dangerous risk of death/crash. I no longer want to be an owner of this Mazda and want to ditch this car for fear of what could have happened to my family; unacceptable safety notification by Mazda. Had myself or children been killed or hurt, I would be suing Mazda. Will Mazda consider offering me any compensation on trading/selling this car?

I want to implore you to make Mazda recall this make/model, with them knowing they have a faulty vvt/timing chain issue, that has affected hundreds, if not thousands of car owners, putting their safety at risk. I have not myself, had the issues yet, that are well documented, but unfortunately I did purchase this car, and it is unbelievable that Mazda will not fix this problem.

Car had severe oil leak found during an oil change with no oil left in the car; however there was never oil on the ground - I park in the garage. I took the car to the dealer for a diagnostic test, they did the dye test and found the leak near the oil cooler from the seal/gasket. This is a very expensive part and it appears to be very common after 80K miles from my searches online. Please investigate as this is very unsafe and needs to be addressed.

* engine issues when the A/C compressor locked up. This is a known issue in this make and model. This happened around 36K miles while I was driving on a freeway. We had to coast into the next exit. * engine knocking issues. They still persist and started around 50K miles. * engine resistance. Alongside the knocking there seems to be a good amount of resistance when taking your foot off of the pedal for acceleration. * they added a factory extension to the radio for the ipod. Ever since they installed this, the rest of the electrical components have been overloaded. - headlights go out frequently. This concerns me as my wife drives the car and I wouldn't want both to go out at the same time. - the battery won't hold a charge if not driven for a few days. The dealership acknowledged that the radio has a 'parasitic draw' on the battery causing these issues, but refuses to take responsibility for their installation. Their solution is to charge $800+ for a new head unit, which is outrageous since I never did anything to the factory head unit.

My Mazda CX7 - 2008 has only 44,000 miles and the engine light went one and after bringing it to a mechanic and checking the codes with a computer, it came up that the egr valve needs to be replaced. All the mechanics that I talked with were really surprise and asked me if the Mazda CX7 - 2008 has a recall on the egv valve because it is not normal that with that little miles the egr valve need to be replaced. I have checked on the internet and I'm seeing many other owners that are having the same issue. I think there is a factory defect with the egr valve for this model.

I have white smoke coming out of my tailpipe when it idles. I also have a burning oil smell in my car. I have to roll down the windows when I get into my car. I have a 2 1/2 year old and I cant imagine its safe for her to breath this in. I took it to green Mazda in springfield il to be repaired, this is a known issue with this vehicle. They installed a ventilation kit. That did not solve the problem. I took it back and now they say there is no problem. So they saw a problem and installed a ventilation kit but now that is doing the same thing there is not a problem. The next step is to replace the turbo, which they will not do. This should be a safety recall.

On Sunday, January 4, 2015, I was driving my 2008 Mazda Cx-7 and I stopped at a stoplight. When I tried to take off when the light turned green, my car hesitated and when I pressed on the gas peddle a little more, it still hesitated then finally took off. All of a sudden, I heard an extremely loud popping noise, and then thick, heavy white smoke started to come out of the tailpipe. The white smoke then started flowing out from under the hood, and it started to come into the car through the air vents. When I tried to pull over and put the car in park, it wouldn't shift into gear, so I pushed the parking break, and it finally stopped. I got out of the car and when I went to grab my purse, I saw fire coming through the bottom air vents ( the ones that blow air on your feet) so I grabbed my purse as quickly as I could, and ran away from the car. Then, I saw part of the engine fall out of the bottom of the car, on fire, and burn into the street. About 5 seconds later, the whole entire car burst into flames. All of the doors were closed, but the intensity of the fire blew both of the passenger side doors open, and blew out all of the windows (including the sunroof, which was closed at the time). When the firefighters finally put the fire out, the car was still smoldering and everything inside was melted. The steering wheel, the seats, the door handles, the mirrors, everything. The fire was so strong that it blew the hood back onto the windshield. All that is left of the car, is just the metal frame, and the engine. The car has a 4 cylinder engine with a turbo feature on it. I believe that is what caused the fire and made the loud popping sound initially.

I write to express my disappointment at the quality of vehicles Mazda is putting out, and the lack of response Mazda's customer service department offers its customers. In 2008 I bought a 2008 Mazda CX7 and this car has given me nothing but problems. From the faulty wiring that always blows out the headlights, to the power windows which sometimes turn off and turn on, to the exhaust fumes that can be smelt inside the car, I've complained about all of it and spent countless resources and time trying to fix it all. The last straw came about a month ago when I was informed that my vvt adjuster and chain were out, the turbo was out and the engine was failing and it would cost me close to $4,000 to repair it. We're talking about a car with only 75,000 miles. According to my mechanic and according to edmunds.com reviews these are all common Cx-7 problems and Mazda just won't own up to them.

The oil cooler on my 2008 Mazda Cx-7 began leaking around the rubber O-ring a few weeks ago. My mechanic called ferman Mazda in brandon, fl to get a replacement and was advised by the service department that the old style oil cooler had problems and Mazda re-designed a new one, and now Mazda owners have to spend over $400 to buy a new one because the rubber gasket and oil cooler are not manufactured anymore. Oil has covered my engine and the plastic engine cover underneath the vehicle. The heat from the engine can cause a fire if it sprays up near the plugs/starter. There is an obvious problem with the oil cooler, however ferman Mazda does nothing to fix the problem for their customers.
