 2010 cx7 grand touring was purchased with 5,844 miles from dealer. we changed the oil & filter every 6,000 miles using recommended oil as shown in the owners manual (5w20). manual recommendation is to change oil every 7,500 miles with normal driving conditions which is the case as my wife drove to and from work. at 37,000 miles, vehicle was started in 20deg f. temps, warmed up for and experienced loud engine knock. once driven, vehicle had no power and had troubles getting to hwy speed. drove the vehicle to the dealer where we purchased it the next day and was informed the engine had excessive engine oil sludge under the oil filler cap. service dept. called me the next day and said they would need to pull the valve cover to investigate further to see if mazda national would cover under warranty. we agreed since we properly maintained the vehicle and had nothing to hide. two days later we received a call from the dealer and were informed there was excessive sludge and they would need to see receipts from where we changed our oil. we performed our own oil changes and did not keep receipts from the auto parts store where we purchased the oil. dealer said without the receipts we would not get warranty work done and charged us $260 to do the investigation to better their case. i called national mazda and all they did was read the notes from the dealer and were not willing to budge. the rep from mazda ([xxx]) was extremely rude and could care less we were experiencing major issues with a car within the warranty. there are numerous claims similar to ours all over the internet. it appears mazda has their standard excessive engine sludge pitch down as this is the common theme in all cx7 engine problems. we had the engine rebuilt at a local shop (paid $6,100) and now are told the turbo is shot as well which is estimated at another $2,000 to replace. *tr

 On october 4 2012 i was told by the mazda dealer service dept that my timing chain and turbo charger on my 2010 mazda cx7 went bad and needed to be replaced. my vehicle only has 39400 miles on it and should be covered under mazdas power train warranty. i was told by mazda warranty department that they would not pay for anything based on sludge build up in the engine. i sent them copies of oil change maintenace as they requested which were done at aprox every 3400 miles as apposed to the required 7500miles. i was told then that they would cover only the timing chain replacement because it was on a recall and that the turbo charger would not be covered at all. they came to this conclusion due to the turbo going bad due to an outside influence what is that i asked and they had no answer. the answer i was givenm is it will not be covered under warranty and that is that and i have basically no recourse.there is clearly a problem with these cx7 as there are so many similar complaints all over the internet and yet mazda refuses to pay on these part that should be covered under the powertrain warranty 6yrs/60,000 miles. the car gets too hot and burns the oil and that is what causes the sludge a manufactures defect not negelcet on oil change and filter maintenance. other mazda owner have the same result wether they oil changed at 3000, 4000, or the required 7500 how can we all have sludge in the engine. obviously there is a manufaturers defect regarding this entire turbo system. mazda needs to own up to the defects regarding the cx7 models and honor the customers warrenty work. the car has so many problems that they are presently not making it anymore. i do not have the money to layout and wait to be rembursed possibly by mazda in the future this is a disgrace. i will never drive another mazda vehicle again and i will not ever reccomend them to any one.

 The turbo made a loud whining noise when the accelerator was pushed and you could not accelerate. alot of white smoke was flowing from the exhaust. we immediately pulled over on our way home from out of town and called aaa to tow the car back to the service dealer in parkersburg wv. the vehicle only has approx. 19,000 miles on it with service records showing proper oil changes. the vehicle is under warranty and mazda sounds like they dont want to cover this problem.
