THE AC ON MY 2007 MAZDA CX-7 STOPPED WORKING WHILE DRIVING ON FREEWAY ABOUT 14 MONTHS AFTER I BOUGHT IT. I HAD AN APPOINTMENT WITHIN A COUPLE DAYS TO BRING IT IN FOR AN OIL CHANGE SO I DIDN'T DO ANYTHING IMMEDIATELY. THE NEXT DAY, WHILE DRIVING LOCALLY I SAW SMOKE COMING FROM THE REAR OF THE CAR AND THEN THE POWER STEERING STOPPED WORKING. I FORCED THE CAR OVER TO THE SIDE AND GOT IT TOWED TO THE NEAREST MAZDA DEALER. AFTER 2 WEEKS WITHOUT THE CAR, THEY FINALLY FIXED IT SAYING THAT THE BELT TENSIONER HAD "FROZEN UP" AND THE BELT HAD MELTED …

WHILE ON A TRIP, OUR A/C STOPPED WORKING ON OUR 2007 MAZDA CX-7. THIS CAR WAS 1 YEAR AND 1 MONTH OLD WE WENT TO THE NEAREST MAZDA DEALERSHIP. PARTS WERE NOT AVAILABLE, AND THE SERVICE TECH TOLD US THAT WE COULD CONTINUE TO DRIVE THE CAR WITHOUT A/C. 200 MILES LATER, THE ENGINE STARTED MAKING SOUNDS AND THE CAR STALLED IN THE MIDDLE OF A BUSY ROAD. WE WERE ABLE TO GET THE CAR RESTARTED AND ATTEMPTED TO GET THE CAR OFF THE ROAD, AND COULDN'T FIND ANY PLACE TO PULL OVER, AND THEN BLACK SMOKE ENGULFED THE CAR. THE CAR "DIED" IN THE MIDDLE OF A B…

AC COMPRESSOR WENT OUT ON MY MAZDA CX7 AFTER ONLY 19K. WHILE I WAS DRIVING ON THE INTERSTATE, THE COMPRESSOR LOCKED AND THE A/C BELT POPPED CUTTING WIRES AND CAUSING SMOKE AND THE SMELL OF AN ELECTRICAL FIRE. I WAS LUCKY ENOUGH TO BE ABLE TO GET OFF THE ROAD BEFORE THE SMOKE TURNED INTO A FIRE. AFTER GETTING ON THE INTERNET, I FOUND OUT THIS IS A POPULAR PROBLEM WITH CX7S ALONG WITH SHOTTY TIRES THAT HAS TO BE REPLACE BETWEEN 10K TO 18K MILES. *TR

TIMING CHAIN REPLACEMENT RESULTED IN A CATASTROPHIC FAILURE OF THE HIGH PRESSURE FUEL PUMP AND ITS HOUSING. REPLACING THE TIMING CHAIN RETURNED THE ENGINE TO PRODUCTION LINE SPECS, THAT WERE TOO MUCH FOR A WORN FUEL PUMP TO HANDLE. THE INCREASED PRESSURE TO THE FUEL PUMP SHATTERED IT INTO NUMEROUS PIECES LESS THAN 100 MILES AFTER THE TIMING CHAIN WAS REPLACED. SAID PIECES BECAME LODGED INSIDE THE CAM SHAFT AND ENDED UP BENDING ALL OF THE VALVES. THE NECESSITATED A COMPLETE VALVE JOB, REMOVING AND REPLACING THE CYLINDER HEAD, FUEL PUMP, CAM …
