NHTSA Complaint #11021175 — 2007 MAZDA CX-7

THE TIMING CHAIN TENSIONERS & BEARINGS THAT KEEP THE CHAIN TIGHT WEAR OUT WAY BEFORE THEIR LIFE SHOULD BE UP. I TOOK THE CAR TO THE MAZDA DEALERSHIP TO HAVE IT LOOKED AT & THE SHOP TECHNICIANS SAID THEY GET THIS PROBLEM WITH THESE CARS ALL THE TIME. ALL THEY HAD TO DO WAS LISTEN WHEN THE CAR WAS STARTED & THEY KNEW EXACTLY WHAT THE PROBLEM WAS. EVEN BEFORE GOING IN I CALLED & SPOKE TO A SERVICE TECH. AS SOON AS I SAID "MY CAR SOUNDS LIKE A DIESEL VEHICLE HE SAID OVER THE PHONE THAT THE PROBLEM WAS WITH THE TIMING CHAIN TENSIONERS AND SUCH. HE ALSO SAID MANY OF THE SAME CARS COME IN WITH THE SAME PROBLEM & HE COULDN'T UNDERSTAND WHY THERE WASN'T A RECALL ON THIS. THAT IS WHY I AM WRITING TO YOU. THE SOUND OCCURS WHEN THE ENGINE IS RUNNING REGARDLESS OF IF WE'RE IN MOTION OR NOT. IF YOU PUT MAZDA CX-7 SOUNDS LIKE A DIESEL IN A BROWSER SEARCH YOU WILL GET MANY RESULTS REGARDING THE TIMING CHAIN ISSUE.
