Problems with 2007 Mazda CX-7 ENGINE AND ENGINE COOLING

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

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! *tr

The a/c compressor on my 2007 mazda cx7 has locked up and needed replacing twice, once at 25k miles and again at 50k miles. *tr

Tl* the contact owns a 2007 mazda cx-7. the contact stated when trying to start the vehicle it failed to start on an intermittent basis. the vehicle was taken to a dealer who advised him that they were unable to diagnose the failure or duplicate it. the vehicle was not repaired. the manufacturer was notified and offered no assistance. the failure mileage was unknown and the current mileage was approximately 26,000.

The air conditioning compressor pulley bearing seized but was able to turn long enough to get to a nearby relative. the dealer said the compressor and belt would be replaced under warranty, but the part would be difficult to get and estimated at least a week or more. he supplied a loaner and said the car would not be safe to drive, as the pulley could seize completely at any time. i am still waiting for the replacement part. *tr

7/17 i brought my mazda cx-7 (2007) to the dealer for repair due to air conditioning not working and making a loud noise coming out of the engine and a bad odor. here is a list of problems found with the car: 1. bad compressor cost to repair $1100 2. front transfer steering case seal leaking cost to repair $1500 3. motor oil seal leak cost to repair $875 4. oxygen sensor melted to the chassis cost of repair $240 5. water pump leak cost of repair $275 the total cost of repair is $3,935 before taxes. this is ridiculous for a 2 year old car. *tr
