Engine Oil Leaking problems of the 2008 Mazda CX-7

Car had severe oil leak found during an oil change with no oil left in the car; however there was never oil on the ground - I park in the garage. I took the car to the dealer for a diagnostic test, they did the dye test and found the leak near the oil cooler from the seal/gasket. This is a very expensive part and it appears to be very common after 80k miles from my searches online. Please investigate as this is very unsafe and needs to be addressed.

The oil cooler on my 2008 Mazda Cx-7 began leaking around the rubber o-ring a few weeks ago. My mechanic called ferman Mazda in brandon, FL to get a replacement and was advised by the service department that the old style oil cooler had problems and Mazda re-designed a new one, and now Mazda owners have to spend over $400 to buy a new one because the rubber gasket and oil cooler are not manufactured anymore. Oil has covered my engine and the plastic engine cover underneath the vehicle. The heat from the engine can cause a fire if it sprays up near the plugs/starter. There is an obvious problem with the oil cooler, however ferman Mazda does nothing to fix the problem for their customers.

The gasket on the oil coolers on these cars are defective. I have an oil leak from this gasket that puts me at risk for an engine blowout. I will have to replace the entire oil cooler at a cost of $500+ because the gasket can't be purchased separately. Mazda needs to take responsibility for this before people get stranded on the road. If you search this oil leak online, you find dozens of posts about this happening to other Cx-7 owners. This is a crossover SUV geared towards families. I drive my kids around in it and now am very concerned about the safety of this car.

The vehicle was taken to an authorized dealer for diagnosis. The engine oil cooler and engine cover were both repaired. The manufacturer was notified of the problem. The failure mileage was unavailable. . . . Updated 04-22-14 the consumer stated the timing chain and vvt actuator was a recall item. The vehicle had not been repaired. Updated 04/28/2014.

I bought the car at 30k miles in November of 2011. I have since driven 15k miles on it. I noticed a click in the engine. I took it to the dealership where they proceeded to tell me that everything was fine and I needed to get a 45k mile maintenance on it. I told them the clicking was bothering me. They said that was fine. I got the car back and the noise appeared to have gone. . . But reappeared after a few days. I went back to the dealership and told them that a car under 5 years old with less than 50k miles on it shouldn't make that noise. They finally admitted there was a problem with the timing chain, causing a leak in the oil which put sludge in the engine. They told me it was my fault etc. I proceeded to look online and there were thousands of other people with the same problem. From the research I have done, they aren't even making the car anymore and I'm sure it's due to these same engine problems. My dealership told me it was my fault. . . Read more...

Mazda using the wrong oil. Recently had the oil changed in my 2008 Mazda Cx-7. When I drove it off the lot the car smoked like crazy. They said they were using the wrong oil so they replaced it with 5w-30 instead of 5w-20. Then car continued to smoke. So next day they put 5w-40 in it. The oil is leaking into the turbo creating a fire hazard.
