2008 Mazda CX-7 engine and engine cooling problems

“I HAD SMOKE COMING FROM UNDER THE HOOD. AC COMPRESSOR WAS BURNING UP, AND ENTIRE AC SYSTEM NEEDED TO BE REPLACED, ONLY FOR THE AC TO STOP OUTPUTTING COOL AIR ON HOT DAYS UNLESS I'M DRIVING OVER 55 MPH. *TR”

“THE AC IN THIS VEHICLE HAS ALWAYS UNDER PERFORMED. IT DID NOT GET REALLY COLD AND HAD TO BE RUN ON THE HIGH SETTING CONSTANTLY. JUST LAST WEEK THE COMPRESSOR FAILED COMPLETELY. *TR”

“EGR VALVE FAILURE ON A 2008 MAZDA CX-7 WITH 47,500 MILES. I HAD NEVER HEARD OF A EGR VALVE BEFORE MY CHECK ENGINE LIGHT CAME ON AND I TOOK IT TO THE LOCAL AUTO PARTS STORE TO HAVE THEM TELL ME THE ERROR CODE. TOOK IT TO THE DEALERSHIP AND THEY TOLD ME THAT THE WARRANTY FOR THE PART WAS 60MONTHS/60,000 MILES. WHILE I WAS WAY UNDER ON THE MILES, I WAS 5 MONTHS OVER ON THE TIME. SINCE THIS WAS MY 3RD TRIP INTO THE DEALERSHIP OVER THE PAST 5 MONTHS DEALING WITH PROBLEMS/MAINTENANCE WITH MY CX-7, I ASKED WHY THIS PARTICULAR PART FAILED. I WAS TOLD THAT IT WAS DUE TO THE NEGATIVE EFFECTS OF ETHANOL. AFTER SOME QUICK RESEARCH, IT IS CLEAR THAT 2007-2008 MAZDA CX-7 HAS SERIOUS PROBLEMS WITH THE EGR VALVE. IT WILL COST ME $650 TO FIX. MAZDA SHOULD HAVE BEEN FORCED TO RECALL THIS PART SINCE IT LOOKS LIKE IT WAS DEFECTIVE FROM THE START. WAS TOLD THAT A NEW REPLACEMENT PART FOR THE EGR VALVE WOULD BE PUT INTO THE VEHICLE WHICH WILL NOT BREAK DUE TO PRESENCE OF ETHANOL IN GAS. *TR”

“HAD TO REPLACE THE A/C COMPRESSOR THAT WENT BAD, WAS A RECALL ON THEM BUT MY WARRANTY WAS OUT. THEN NOW 11/8/13 I AM BEING TOLD THAT MY EGR VALVE IS BAD AND NEEDS TO BE REPLACED AND IT SO HAPPENS GUESS WHAT THE EMISSIONS WARRANTY HAS RAN OUT. I HAVE SEEN A LOT OF COMPLAINTS ON LINE ABOUT THE A/C COMPRESSOR AND NOW THE EGR VALVE. *TR”

“I WAS DRIVING AT ABOUT 25MPH WHEN I NOTICED A BURNING SMELL. I PULLED OVER AND POPPED THE HOOD AND SAW SMOKE COMING FROM THE AC COMPRESSOR. IT TURNS OUT THAT THIS IS COMMON FOR THIS MODEL. MAZDA EXTENDED THE WARRANTY BUT OF COURSE MINE EXPIRED THIS YEAR. IT'S JUST A SHAME THAT MY CAR HAS LESS THEN 40K MILES AND MAZDA HAS ACKNOWLEDGED THIS IS AN INFERIOR PART, BUT WONT HELP COVER THE COST. THERE ARE HUNDREDS OF REPORTS OF THIS PART FAILING AND BREAKING THE SERPENTINE BELT CAUSING THE CAR TO LOSE ALL POWER. THIS SHOULD ABSOLUTELY BE A RECALL. IMAGINE THIS HAPPENING WHILE ON A HIGHWAY OR TURNING AT AN INTERSECTION. *TR”

“AIR CONDITIONING BEGAN BLOWING HOT AIR. MANY COMPLAINTS LOGGED ONLINE FOR THIS YEAR VEHICLE HAVING THE SAME ISSUE. CONTACTED THE DEALERSHIP TO FIND THE WARRANTY HAS EXPIRED 3 WEEKS PRIOR TO THIS ISSUE. RECOMMENDATION WAS TO CONTACT MAZDA CUSTOMER SATISFACTION. THEY PROVIDED A FILE NUMBER AND INFORMED I NEEDED TO HAVE THE DEALERSHIP CONFIRM THE ISSUE WAS THE COMPRESSOR. THE DEALERSHIP DID CONFIRM THE COMPRESSOR AND BELT NEED REPLACED. CONTACTED THE CUSTOMER SATISFACTION NUMBER BACK AND THE APPEAL/COMPLAIN PROCESS BEGAN TO SEE IF THEY WOULD PROVIDE FINANCIAL ASSISTANCE IN REPLACING THE COMPRESSOR AND BELT SINCE THE WARRANTY HAD JUST EXPIRED AND ONLY HAS 28,000 MILES. WAS INFORMED 2 DAYS LATER THAT THE DECISION WAS THAT THEY WOULD NOT PROVIDE ANY ASSISTANCE SINCE IT IS OUT OF THE WARRANTY PERIOD. VERY DISCOURAGED THAT A CORPORATION WOULD NOT STAND BEHIND THEY VEHICLE UNDER THESE CIRCUMSTANCES AND THE FACT THAT THEY KNOW THIS VEHICLE HAS THESE ISSUES. I COULD UNDERSTAND IF THE VEHICLE HAD 60,000 MILES BUT THIS IS VERY DISAPPOINTING. *TR”
