SOURCE: Timing chain broke on a 2007 cx7 w 65K miles
you need to take it to your local dealer and raise a big fuss because this is a known problem and if you yell loud enough you should be able to get this fixed under warranty.

We just had the same problem in Dec 2010. Purchased ours new Feb 2008. Mazda is aware of the issue. They will not fix it if it is out of warranty, but we have been going to the same dealer for service so they offered to pay for the part (EGR @ $450) if we payed for the labor @ $350. We had several problems with the vehicle, from the turbo failing to motor mounts failing to scraping brakes to rattles that would not go away. The problem is the turbo engine is not burning the fuel well enough so the carbon is coming back into the system past the EGR and clogging the system up. Not sure if it's an ethenol fuel related issue or octane issue. Too much unreliable technology. We sold ours the day after we fixed the EGR issue (w/ 50k miles). It was fixed and running fine, so we didn't feel guilty about passing it on. Just kept reading about needing to save for a new engine around 80k miles b/c of clogged engine valves. We went back to Honda...
