2009 MAZDA CX-7 Engine Problems

TL* THE CONTACT OWNS A 2009 MAZDA CX-7. THE CONTACT STATED THAT THE FRONT DRIVER SIDE WINDOW AND BOTH REAR WINDOWS FAILED TO OPERATE AS INTENDED GOING UP AND DOWN. THE TIRE PRESSURE MONITOR LIGHT ILLUMINATED AND REMAINED DESPITE HAVING THE TIRES CHECKED FOR PROPER TIRE PRESSURE AND FOLLOWING THE INSTRUCTIONS PROVIDED TO RESET THE TIRE PRESSURE LIGHT. ADDITIONALLY, THE CHECK ENGINE WARNING LIGHT WAS ILLUMINATED. THE CHECK ENGINE WARNING LIGHT WAS RESET BY AN INDEPENDENT MECHANIC. THE CONTACT STATED THAT WHILE DRIVING AT 55 MPH THE VEHICLE DECELERATED TO 20 MPH AND STALLED. THE VEHICLE WAS TAKEN TO THE INDEPENDENT MECHANIC AND WAS INFORMED THAT THE MASS AIRFLOW SENSOR AND OXYGEN SENSOR NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURES. THE APPROXIMATE FAILURE MILEAGE WAS 98,800.

THE MAZDA HAS MULTIPLE ISSUES WITH TURBO BOOSTER FUNCTIONING AND MALFUNCTIONING CAUSING AIR POLLUTION ISSUES WITH BILLOWING WHITE SMOKE FR TAILPIPE, MAZDA DOES NOT WARRANTY THIS BY ONGOING ISSUES WITH SOME REPAIRS HAVING TO BE DONE AS EARLY AS 60000 MILES,. MY CAR IS LESS THAN 100000 MILES WITH EXTENSIVE REPAIR REQUIRED TO RESOLVE ISSUE, REPAIRS AS EXPENSIVE AS 3000 DOLLARS. THE SMOKE IS SO THICK IS IMPAIRS THE VISION OF CARS THAT MAYBE BEHIND VEHICLES WITH THIS PROBLEM. THIS ISSUE NEEDS TO BE REVIEWED AND RESOLVED, CAR OWNERS SHOULD BE MADE AWARE WHEN PURCHASING THESE MAZDA OF THIS HEAVILY UNRELIABLE IMPORTANT PART OF THE VEHICLE TO MAKE THE DECISION BEFOREHAND IF THEY WILL BE RESPONSIBLE FOR THESE EXPENSIVE REPAIRS SHOULD THEY OCCUR.

THE EXHAUST FROM THIS CAR IS HORRIBLE. CAUSING BREATHING ISSUES

TURBO LEAK CAUSING LACK OF POWER. THIS PROBLEM SAID TO COST 2300 DOLLARS AND STILL MAKING PAYMENTS. THE MECHANIC SAID IT CAN CAUSE A FIRE. IT IS ALL OVER INTERNET THAT THIS IS A PROBLEM FOR MOST OWNERS. WHY. I RECALL?

I TOOK MY 2009 MAZDA CX-7 (108,000 MILES) IN TO THE DEALERSHIP FOR AN OIL CHANGE AND TO SEE WHY THE CHECK ENGINE LIGHT HAD COME ON. I WAS INFORMED THE TURBO NEEDED TO BE REPLACED AND WAS ADVISED THAT THE CAR WAS UNSAFE TO DRIVE AND THAT I NEEDED TO GET A NEW CAR IMMEDIATELY. THE DEALERSHIP WAS HESITANT TO LET ME LEAVE IN THE CAR AS IT COULD STOP WORKING AT ANY TIME AND BECAUSE I DO A SIGNIFICANT AMOUNT OF HIGHWAY DRIVING THIS IS PARTICULARLY ALARMING. NO REMEDY WAS OFFERED AND I WAS TOLD IT WASN'T WORTH REPAIRING. THIS IS A KNOWN ISSUE WITH THE CX-7 AND A DANGER TO THE DRIVER AND OTHER DRIVERS AROUND WHEN THE CARS STOP WORKING DUE TO THE ISSUES WITH THE TURBO. A RECALL NEEDS TO BE ISSUED IF SO MANY PEOPLE ARE HAVING THIS ISSUE WITH SERIOUS SAFETY CONCERNS.

WHILE DRIVING DOWN THE INTERSTATE, VEHICLE LOST MUCH OF IT'S ACCELERATION, AND BEGAN MAKING A LOUD WHINING NOISE. PULLED OFF THE HIGHWAY AND INVESTIGATED THE NOISE. IT WAS A LOUD WHINING THAT ONLY OCCURRED IN NEUTRAL AND PARK OVER 2500 RPM AND WITH ANY ACCELERATION WHILE IN GEAR. ALSO NOTED YELLOW FOAMY OIL ON THE DIPSTICK WHICH WAS 4.5 QUARTS LOW BEING VERY CLOSE TO TIME TO GET A CHANGE. TOWED TO THE SHOP TO DISCOVER THAT THE VEHICLE IS BURNING OIL AND THE TURBO HAD GONE BAD. MECHANIC SUSPECTS THAT THE TURBO GOING BAD IS WHAT WAS MOST LIKELY BURNING OIL AND RETAINING WATER IN THE CRANKCASE. *TR

STARTING HEARING A NOISE INITIALLY--NOT SURE WHERE IT WAS COMING FROM BUT THOUGHT IT WAS INTERNAL TO THE ENGINE. TOOK IT TO THE DEALER FOR INSPECTION AND THEY VERIFIED THAT THE FRONT OF THE ENGINE WOULD HAVE TO BE REMOVED TO REPLACE THE DEFECTIVE PART. I CAN NOT REMEMBER THE PART NAME BUT IT WAS CLEAR FROM THE DEALER REP THAT MY CAR WAS ONE OF MANY THEY HAVE REPLACED. I SPENT $1244.00 IN REPAIRS ON MY VEHICLE THAT THE MAZDA DEALERSHIP ACKNOWLEDGED WAS A FACTORY DEFECT ON MY CAR AND MANY OTHERS. JUST NOT RIGHT *JS

MY 2009 CX-7 HAS A MAJOR OIL LEAK AT THE OIL COOLER. UPON LEARNING THIS I TURNED TO MY MECHANIC AND THE INTERNET ONLY TO FIND OUT THIS SEEMS TO BE A VERY COMMON ISSUE. THIS DEFECT IS SOMETHING THAT IS ON EVERY MAZDA FORUM AND SHOULD BE MADE A RECALL AND FIXED. THIS IS A VERY WELL MAINTAINED VEHICLE THAT SHOULD NOT HAVE THIS TYPE OF ISSUE AT THIS MILEAGE. *TR

I WAS DRIVING ON A HIGHWAY. I HEARD A HIGH PITCHED SQUEALING SOUND THEN SMOKE STARTED BLOWING OUT OF MY CAR. I COULD NOT SEE, AND THE OTHER DRIVERS BEHIND ME LOST VISABILITY TOO. IN THE MIDDLE OF THIS BLINDING SMOKE, SURROUNDED BY HUGE TRUCKS, I LOST ACELERATION. MY INSTRUMENTATION PANEL DID NOT HAVE ANY WARNING LIGHTS ON. I WAS DRIVING BLIND. I PULLED OFF THE HIGHWAY AS QUICKLY AS POSSIBLE, AND HAD MY CAR TOWED TO A DEALERSHIP. THE DEALERSHIP SAID MY TURBO BLEW OUT, (WHICH I GUESS SUCKED ALL THE OIL OUT OF THE CAR) I NEED A VVT VALVE AND THE TIMING CHAIN IS STRETCHED. ON A CAR WITH 57,000 MILES! IN CHECKING ON LINE, I FOUND THIS HAS BEEN A PROBLEM WITH THE CX-7 FOR 6 YEARS AND THEY ARE NO LONGER MAKING THIS MODEL. I SEE THAT MAZDA DEALS WITH THESE PROBLEMS BY STATING THE...

APPARENTLY THE DESIGN OF THE TURBO AND THE ENGINE CREATES HOT SPOTS IN THE ENGINE, ESPECIALLY IN THE TURBO. THESE HOT SPOT CREATE SLUDGE BUILD UP WHICH EVENTUALLY EFFECTS THE PERFORMANCE AND RELIABILITY OF THE ENGINE. RESEARCH ON THE INTERNET SHOWS THIS TO BE A PROBLEM FOR A CONSIDERABLE AMOUNT OF OWNERS OF THIS VEHICLE. MAZDA HAS REFUSED TO CORRECT THESE PROBLEMS UNDER THEIR WARRANTY. ALSO LACKING BY MAZDA, SINCE IT IS APPARENTLY A MAJOR CAUSE OF LARGE BUILD-UPS OF SLUDGE, IS THE NECESSITY TO IDLE THE ENGINE FOR THREE MINUTES PRIOR TO TURNING OFF. THIS WAS NEVER EXPLAINED TO US WHEN THE VEHICLE WAS PURCHASED. *TR

AS I PULLED OUT OF MY PARKING LOT AT WORK I LOST POWER SO I DROVE THE CAR TO THE DEALER. THEY CALLED AND TOLD ME THE TURBO WAS BAD DUE TO BEING CLOGGED WITH SLUDGE. AND, THAT DUE TO THAT SLUDGE THE ENTIRE ENGINE WOULD HAVE TO BE REPLACED AT A COST OF $8,900. I'VE ONLY OWNED THE CAR 9 MONTHS, HAVE RECEIPTS FOR MULTIPLE OIL CHANGES, AND HAD AN EXTENDED WARRANTY - HOWEVER, THE EXTENDED WARRANTY COMPANY (AMERIPLUS) STATES THAT BECAUSE THE PROBLEM WAS CAUSED BY SLUDGE, I'M NOT COVERED. I'VE RESEARCHED AND DISCOVERED THAT THIS IS A HUGE PROBLEM WITH THIS VEHICLE, PLEASE HELP ME! *TR

AROUND THE END OF APRIL 2012 I NOTICED THAT MY MAZDA STARTED MAKING A LOUD NOISE - COMPARABLE TO A SEMI OR DIESEL TRUCK. THE NOISE WAS CONSTANT, REGARDLESS OF SPEED, AND MAINTAINED AT THE SAME LEVEL AS LONG AS THE CAR WAS ON. I TOOK THE CAR TO MAZDA ON MAY 12TH TO DETERMINE THE CAUSE OF THE NOISE. WITHIN A FEW HOURS OF DROPPING THE CAR OFF, THE DEALERSHIP CALLED ME BACK AND ADVISED THAT IT WAS THE VVT SYSTEM THAT WAS CAUSING THE NOISE AND IT NEEDED TO BE FIXED. ALL THEY NEEDED WAS MY OIL CHANGE RECEIPTS TO COVER THIS REPAIR UNDER WARRANTY. I ADVISED THEM THAT I DON'T KEEP ALL OF MY OIL CHANGE RECEIPTS; THAT I GO TO VARIOUS BUSINESSES EACH TIME I GET AN OIL CHANGE BASED ON WHO HAS A SPECIAL, COUPONS, NEAREST LOCATION ETC. I WAS THEN TOLD WITHOUT THE RECEIPTS...
