while driving on the highway i heard a ticking noise after a few seconds later the car lost power and smoke came out of the exhaust. when i pulled over i took the cover off from the engine and noticed that there was oil coming out from where the top of the oil goes.the oil pressure on the block was compromised due to failure of the turbo. when taken to the roger beasley mazda dealership and the car was cranked the dip stick shot out from the engine. the dealership indicated that there was carbon build up but could not explain why. the car was towed to another acs certified mechanic and confirmed that the engine failure was due to the failure of the turbo. before taking the trip on 4-18-2013 i took my car the mazda of mesquite dealership because i heard a ticking noise and the technician indicated that the noise was normal. also the technician performed msp 36 reflashed pcm with updated software and cleared all fault codes since there was a recall. three weeks later the engine goes out. the manufacture warranty expired, but have a in service warranty. the in service warranty agency denied the claim indicating that it was not normal wear and tear of the engine failure. i contacted the dealership and also emailed the manufacture to express my concern and both agencies directed me back to the in service warranty. both the dealership and in service warranty are not willing to assist in the cost being that the cx7 model is a lemon in my opinion. there have been many claims against this model by other consumers in which was confirmed by the employees at the georgetown roger beasley mazda dealership. the employees indicated that the cx7 model has a lot of problems that is why the cx5 replaced the cx7 model. since the claim was denied i have spent over 1000 which does not include any repairs, on a side note i was 300 miles away from home. *tr
check engine light due to the egr valve = exhaust gas recirculation valve being stuck in the open position with 51k miles. the dealership replaced the valve (part number l3k9-20-300a) and the gasket (part number lf6t-20-305) for $882.63 being that it was not covered under my certified pre owned warranty or my extended warranty since it is part of the emissions package i paid, in full, out of pocket. i have checked several online forums and have seen this is a common occurrence for 2007 cx7 between 25k and 55k miles. i think this is a much larger problem than regular wear and tear requiring an investigation. *tr
dt*: the contact stated upon acceleration, the vehicle hesitated. it was driven to the dealer who determined the control module computer in the power train needed to be reprogrammed. the vehicle was a 2007 mazda cx-7. *ak updated 10/31/2006 - right front window failed. the dealer replaced the left front switch. *nm

i bought a brand new mazda cx-7 in july 2007. i took it to the service department on august 9th because of a loud noise from the rear interior. the dealer service department informed me that the noise was from the rear mid seat belt that retracts into the roof. they informed me that the seat belt had not been fitted correctly at the assembly plant and that the seat belt was inoperative. they ordered a new seat belt and replaced the original belt. before taking the vehicle back to the dealer i had been driving my young children in the rear seat on the assumption that the seat belt worked and my child was safe. i am concerned that if the assembly plant can fit a seat belt that is inoperative once and it passes all the plant quality checks, they can do it many more times. how many mazda vehicles have been fitted with rear seat belts that are inoperative? *jb
mazda cx7 (fwd) exhibits abnormal tire wear(cupping,feathering) on all (4) tires after less than 1000 miles. brought the car into the purchasing dealer who re-balanced and realigned. tires continued to exhibit the same wear after 2000 miles and ride at highway speeds had some vibration and rough feel at lower speeds. dealer once again realigned vehicle and increased the psi on all 4 tires to 36psi. at just over 5000 miles vehicle was brought into dealer again, still continuing to show abnormal wear and poor ride at highway speeds (vibration & rough). dealer realigned and re-balanced all wheels and once again increased tire inflation to 36psi. i later contacted the service mgr and told him that i did not like the fact that he increased the tire pressure over the manufacturers recommended settings and that this would cause the tire to wear down the center quickly. *jb

after short duration idol "5-10" minutes car blew heavy white and black smoke out of exhaust followed with a clanking/rattling sound from the rear of car. three time this happened in a short 4-7 mile drive home. took it to the dealer and at first the said they could not duplicate the problem but updated the engine and transmission computer program. then they let the car idol for some time and it blew the smoke and heard the sound. so they decided after calling and reporting the event to the regional manager to replace the turbo. i have looked on-line about these problems and have come across owners that have had their turbos replaced a few times and the problem still exists. when the parts are in and they replace the turbo, i will see if this is a fix. i have very little faith that this will fix the problems this vehicle has. and it has many. *tr
