I have had my 2007 Mazda Cx-7 for less than one year. I stopped at a red light after exiting the highway and my car engulfed in thick white smoke. I had the car towed to a local shop per my insurance company to have it checked out. The repair shop at first called to tell me it was the starter, and that it would cost 600 to fix it. Come to find out that not only the starter blew, but it also ruined the alternator as well as the fuses on the battery. I was told by Mazda that this is not a common occurrence. The total of the repairs is now over 1200. The vehicle has been meticulously maintained throughout its lifespan and is at 92,000 miles.

An excess of white smoke emitted from exhaust upon acceleration after a brief period of idle. It was determined that a faulty turbo charger was to blame. So the car was in the shop for 7 days while they replaced the turbo. Several months later the car wouldn't start after sitting in a heated garage overnight. It sounded as though the cylinders weren't firing properly. Car was towed to mechanic who identified issue as fouled cylinder heads from prior failure of turbo. This time the entire engine was replaced. Again the car was in the shop for approximately seven days. Some months later an oppressive amount of road noise appeared at all speeds on all road surfaces. We were directed that the tires were to blame. After replacing all 4 tires at a cost of nearly $800 the sound persisted. Upon further inspection the technician found that the wheel speed sensors on the rear wheels had failed allowing water to seep in and rust rear wheel bearings. All four wheel bearings where replaced. Today the vehicle is again in for engine repair to replace the oxygen sensor and a dead battery. After owning the car for 18 months it is has been in the shop for a total of approximately 4 weeks.

I have my 2007 Mazda for a year and it has been at the dealership for 1/2 the time I've owned it. It is the worst vehicle that Mazda could have made it needs to be recalled because of numerous problem someone is going to lose there life. I have had so many things done to my vehicle actuator 2 oil on the engine, turbo went out, timing belt, tie rod broke and tire came off and hit a truck, air conditioning went out, the list can go on and on just got it back after being repaired and it has to go back to the shop on Friday this is the worst car in the world it is a lemon Mazda should be shame of themselves for selling this piece of crap.

I have a 2007 Mazda Cx-7. it is a very beautiful car but also has tons of problems. At 15000 miles it was leaking oil and they replace the engine gaskets. Then later was also leaking oil. Was told by the dealer that it was not. Took it to someone else who said it was leaking from the timing chain. Mazda resealed it. Since then my car doesn't shift properly going up and down hills. My air conditioner is hot and makes a funny sound. My car has loss of power and sound like a diesel. Overall I think that Mazda needs to step up and take care of the problems or they will not get many returning customers! something needs to be done! it was a 35000 dollar car!

I got into a Mazda forum where many costumers are having problems with the air conditioning clutch failure (seized) loosing power steering while driving. Turbo failure, causing engine overheating. Timing belt failure. I can not find any recalls about these failures.
