MAZDA STATES THIS PART DOES NOT FALL UNDER EMISSIONS WARRANTY. AFTER DOING SOME RESEARCH, THIS APPEARS TO BE A COMMON PROBLEM WITH MAZDA'S AND I DON'T FEEL I SHOULD BE PAYING $1200.00 TO FIX A VEHICLE THAT IS ONLY TWO YEARS OLD. MAZDA H…

THE CHECK ENGINE LIGHT CAME ON SO I TOOK IT TO THE DEALERSHIP. TURNS OUT THE TIMING CHAIN, GASKETS, LOCK, AND BOLT, OIL PAN GASKET, AND EGR VALVE NEED TO BE REPLACED. THE CAR ONLY HAS 37,437 MILES ON IT. TO HAVE MAJOR ENGINE PROBLEMS IS RIDICULOUSLY UNSAFE. MAZDA HAS MANY CASES WITH THESE SAME ISSUES AND YET HAS NOT ISSUED A RECALL. EVEN WITH THE WARRANTY COVERING ENGINE PARTS/LABOR IT'S ABSU…
Common questions
How serious is the engine problem on the 2008 Mazda CX-7?
It's a meaningful issue. 68 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $3,100.
At what mileage does the engine typically fail?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to engine?
