Manifold/header/muffler/tail Pipe problems of the 2008 Mazda CX-7

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. 00 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?.

The contact owns a 2008 Mazda Cx-7. The contact stated that white smoke emitted from the tail pipe. The vehicle was taken to the dealer who stated that the failure was due to poor maintenance and that the turbo needed to be replaced. The contact also mentioned that the failure was previously experienced. The technician also stated that there was a blown head gasket. The vehicle was not repaired. The manufacturer was contacted about the failure. The failure mileage was approximately 81,000. Updated 12/31/cn the dealer informed the consumer the turbo failed due lack of maintenance and not enough oil changes.

I purchased the 2008 Mazda cx7 about 2 weeks ago and already replaced the compressor I first had white smoke coming out the tail pipe well I didn't think anything of it until someone told me that is not normal so a week later I started hearing noises like a diesel truck and a knocking noise so the next day I went to the dealership that sold me the vehicle and we drove the vehicle and he stated it was fine he then drove again and the vehicle locked up and they told me the compressor locked up now I'm hearing a ticking noise from the engine and they stated it was normal but it still concerns me cause reading other statement have me worried that the engine vavle will be next and I don't have money to repair a vehicle I'm a single parent of 4 kids.

Purchased my 2008 Mazda cx7 brand new 12/08/2008. Started noticing white smoke coming out of the tail pipes while idling and I lived in south florida at the time. Dealership stated that the car was leaking oil and they wanted to fix the problem by putting in oil that would cost over $100 per oil change. After putting in the oil the problem continued. Took the car to the dealership again and they then stated that the only fix would be to replace the turbo and that I had to contact corporate to get it fixed. After speaking with corporate the turbo was replaced, but I am now having white smoke coming from the back of the car again and I am at 45,500 miles. This is a problem that I see listed often on this site and with some cars starting on fire. I hope that would not happen, but if Mazda has changed the turbo due to this problem in newer models a recall should be looked at to keep the problem from occurring.
