2009 Mazda CX-7 Engine Problems

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.

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

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

THE AIR COMPRESSOR WENT ON MY VEHICLE AND NEEDED TO HAVE IT TOTALLY REPLACED. THE AIR CONDITIONING NVER REALLY WORKED ALL THAT WELL ANYWAYS WITH THE CAR NEVER GETTING VERY COOL. *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 I WOULD HAVE TO PAY $4000 FOR THE REPAIR. AFTER DOING A LOT OF RESEARCH ON THE INTERNET, I'VE DISCOVERED THAT THIS PROBLEM IS CAUSED BY FAULTY PARTS USED BY MAZDA - AND NOT BY POTENTIAL NEGLECT FROM THE CONSUMER. THERE'S CASE AFTER CASE OF PEOPLE REPORTING SIMILAR PROBLEMS IN THEIR CX7, MAZDA REQUIRING OIL CHANGE HISTORY, AND SERVICE BEING DENIED REGARDLESS IF APPROPRIATE HISTORY IS PROVIDED. UPON FURTHER INSPECTION THE TECHNICIANS FIND "OIL SLUDGE" IN THE VEHICLE AND QUICKLY DETERMINE THAT IT'S THE FAULT OF THE CONSUMER. I'VE NOW BEEN ASKED TO BRING MY CAR BACK INTO THE DEALERSHIP FOR FUTHER DIAGNOSIS. I TOLD BOTH THE REPRESENTATIVE AT THE WARRANTY DESK AS WELL AS MY SERVICE MANAGER AT THE DEALERSHIP THAT BASED ON MY RESEARCH ONLINE, I ALREADY CAN PREDICT WHAT WILL BE FOUND AND WHAT WILL BE SAID TO ME. I NOTED THAT MAZDA RECENTLY ISSUED A LETTER OF JANUARY OF THIS YEAR EXTENDING THE WARRANTY OF THIS VERY PART BECAUSE OF THE ON GOING ISSUES. SO THIS ISN'T SOMETHING THEY'RE UNAWARE OF - IT'S JUST SOMETHING THEY ARE (WRONGLY) REFUSING TO COVER ON THEIR WARRANTY. SOMETHING NEEDS TO BE DONE ABOUT MAZDA'S NEGLECT!

WE LEASED A 2009 MAZDA CX-7 (GARAGED AND HIGHWAY DRIVEN ONLY). THERE WAS NEVER A PROBLEM. THE BATTERY DIED. WE CHANGED THE BATTERY. CAR STARTED AND THEN DIED. AFTER ONE MONTH, IT AGAIN HAD BEEN FLAT BEDDED BY MAZDA. THEY DID A CHECK AND TOLD ME THEY COULD NOT FIND ANYTHING WRONG WITH THE ELECTRICAL SYSTEM, BUT THEY FOUND SLUDGE IN THE ENGINE COMPARTMENT. THEY HAD A RECALL ON A VALVE WHICH I NEVER RECEIVED IN THE MAIL. THE CAR ONLY HAD 17,000 MILES ON IT. AFTER 3 YEARS, MAZDA CAME BACK AND SAID THEY WOULD COVER UNDER LEASE OR EXTENDED WARRANTY, WHICH I HAD. THEY SAID IT WOULD COST $9,500 TO REPLACE AN ENGINE WITH A 17,000-MILE LEASED CAR AND THEY WOULD NOT STAND BY THEIR PRODUCT. I WANT TO START A LAWSUIT ON THE CAR AS I HAVE HAD MANY LEASES WITHOUT THESE PROBLEMS EVER AND LEASED OVER 10 CARS IN THE LAST COUPLE OF YEARS WITH NO PROBLEM. *JS

IN JANUARY 2012, I RECEIVED A LETTER FROM MAZDA INC THAT THE COMPANY WAS EXTENDING THE WARRANTY ON THE TIMING CHAIN TO 70,000 MILES. IN THE LETTER, IT STATED THAT A CERTIFIED MAZDA DEALER COULD INSPECT THE VEHICLE TO DETERMINE IF THE TIMING CHAIN HAS A PROBLEM. ON FEB 24 THE VEHICLE WAS INSPECTED BY A CERTIFIED MAZDA GARAGE AND WHEN MY HUSBAND WENT TO PICK IT UP, THEY SAID "IT HAS A SLIGHT NOISE BUT NOTHING BIG.THEN THEY ASKED FOR ALL THE RECEIPTS FROM THE OIL CHANGES. NOW, WE BOUGHT THE CAR IN MARCH 2009, THEREFORE WE WOULD HAVE NO RECEIPTS FOR THE PAST YEAR AND A HALF THE CAR WAS WITH ANOTHER OWNER. WE ONLY HAD 3 RECEIPTS B/C MY HUSBAND ROUTINELY CHANGE THE OIL . NOW, THE OTHER THING WAS IN EARLY FEBRUARY, THE VEHICLE BEGAN TO NOT START ALL THE TIME. IT WAS TAKEN TO OUR LOCAL GARAGE AND THE REPAIR MAN SAID IT COULD BE A NUMBER OF THINGS, BUT SINCE IT HAS THE TIMING CHAIN ISSUE...THAT COULD BE ONE OF THE PROBLEMS THAT CAUSES A CAR NOT TO START. IT LEFT ME STRANDED ON 3 OCCASIONS. SO,FROM FEBRUARY UNTIL MARCH 30, MY HUSBAND ARGUED WITH MAZDA AND THE DEALERSHIP THAT FIRST INSPECTED THE VEHICLE. THE DEAL WAS MAZDA WAS NOT GOING TO PAY FOR A NEW TIMING CHAIN B/C WE COULDN'T PRODUCE OIL CHANGE RECEIPTS AND IF THERE WAS SLUDGE IN THE MOTOR "THIS COULD BE WHY". SO ON MARCH 30, THE MAZDA DEALERSHIP CALLED AND SAID FOR $180 THE GASKETS COULD BE PULLED TO SEE IF THERE WAS SLUDGE. WHICH IN ALL THE REPORTS THAT I READ ON THIS WEBSITE, MAJORITY OF ENGINES HAD SLUDGE B/C THE MOTOR BURNS THE OIL TOO HOT. THE OTHER REPAIRS THAT VEHICLE HAD: 2010 -AIR CONDITIONER COMPRESSOR (IT WAS RECALLED) ($900), A NEW STARTER ($300), DEC 2011- RT REAR WHEEL BEARING ($600), FEB '12- NEW BATTERY ($100) WHICH DIDN'T NEED TO BE REPLACED B/C IT WAS PART OF THE TIMING CHAIN PROBLEM.SO ON APRIL 4, WE TRADED THE VEHICLE AND BOUGHT A 2009 HONDA CR-V. MY HUSBAND AND I WILL NEVER BY A MAZDA AGAIN.

I BOUGHT THIS USED AROUND JUNE 2010 WITH APPROX. 16000 MILE. I HAD OIL CHANGE AT THE LOCAL GARAGE STATION. THEY TOLD ME THAT THE OIL WAS VERY THICK. SO I HAD IT CHANGED AGAIN WITHIN THREE MONTH. IT WAS RUNNING FINE WITHOUT ANY INDICATION AND ALL OF A SUDDEN I LOST THE POWER AND ENGINE QUIT. I HAD IT TOWED TO GARAGE AND THEY TOLD ME THAT IT IS BETTER WE HAVE IT CHECKED BY DEALER AS THIS HAS WARRANTY. MAZDA DEALER LOOKED IN TO THIS AND TOLD ME THAT THE TURBO ENGINE IS RUINED DUE TO GUNK IN THE OIL. THEY ASKED ME FOR OIL CHANGE RECORD. I ONLY HAD SINCE I HAD IT . I COULD NOT GET ANY PREVIOUS RECORD. MAZDA AND DEALER TOLD ME THAT THE WARRANTY IS VOID DUE TO NEGLIGENCE TO MAINTAIN. THEY WILL NOT COVER UNDER WARRANTY. I CAN NOT BELIEVE THIS. THIS CAR HAS ONLY 35K MILE AND NO INDICATION AND MAZDA DO NOT PROVIDE ANY KIND OF WARRANTY ASSISTANCE. ANYONE ELSE HAD THE SAME ISSUE WITH MAZDA CX-7? I THINK THIS IS SOMETHING TO DO WITH TURBO. *TR

I OWN A 2009 MAZDA CX 7 TURBO. THE VEHICLE HAS HAD IT'S PROPER OIL CHANGES BY A SERVICE GARAGE NOT A "QUICK LUBE" PLACE. THE OIL WAS CASTROL GTX 5W-30W, WITH FROM OIL FILTER.THE LONGEST INTERVAL BETWEEN OIL CHANGES WAS 6000 MILES AND THE SHORTEST 4000 MILES. THE VEHICLE NOW HAS 45,664 MILES ON IT AND THE WIFE COMPLAINED ABOUT A HIGH PITCHED NOISE AND LACK OF PERFORMANCE . BROUGHT TO THE MAZDA DEALER, THE DEALER SAID THE TURBO WENT AND THAT MAZDA WILL NOT COVER IT UNDER WARRANTY (60,000 WARRANTY ON DRIVE TRAIN AND TURBO) BECAUSE OF ENGINE SLUDGE !! ARE YOU KIDDING ME...ENGINE SLUDGE, THE PROPER OIL VISCOSITY WAS USED AT PROPER INTERVAL (MAZDA SAYS 7500 BETWEEN OIL CHANGES). NO SIGNS OF OVER HEATING, HIGH ENGINE TEMPS, THE VEHICLE IS DRIVEN TO WORK AND BACK (4 MILES AWAY) 2X'S PER DAY 6 DAYS A WEEK. SOUNDS TO ME LIKE ENGINE OIL IS NOT GETTING UP TO TEMP. AND THIS IS CAUSING THE SLUDGE, MAZDA DOES NOT STATE THIS ANYWHERE ANY TIME IN THEIR MANUAL. I FOUND THIS OUT ONLY AFTER RESEARCHING ON LINE....ANYONE ELSE HAVING ISSUES WITH THEIR MAZDA ???? I'VE OWNED TURBOS BEFORE AND NEVER HAD ISSUES. MY VEHICLE GETS IT'S OIL CHANGE BY THE SAME STATION AND THIS NISSAN HAS 190,000 MILES ON IT WITH NO PROBLEMS AND NO SLUDGE !!! *TR

I BOUGHT THE 2009 MAZDA CX7 IN MARCH OF 2009. ABOUT MID AUGUST TO EARLY SEPTEMBER 2009 THE CAR WOULD BEGIN TO JOLT BACKWARDS (WHEN PUT IN REVERSE) OR FORWARD (IN DRIVE) WHEN I WOULD BE READY TO LEAVE. SOON AFTER IT WOULD STALL TO GO UP HILLS OR TO PICK UP SPEED WHEN GETTING ON THE INTERSTATE. LATER I WOULD FUEL THE CAR TOA "FULL TANK" AND THE GASOLINE WOULD SPILL ALL BACK OUT. I CALLED AND FILED A COMPLAINT @ 2 DIFFERENT TIMES AT WHICH THE DEALERSHIP COULD NOT FIND ANYTHING. LATER CALLING ME BACK STATING THAT THE O2 WAS MESSED UP AND FIXED ABOUT (EARLY FEBRUARY 2010 IS WHEN IT WAS IN THE SHOP). I WAS WITHOUT A VEHICLE FOR 1 1/2 WEEKS. AFTER BEING LOOKED AT & FIXED, I LATER PUMPED GASOLINE AND IT REPEATED THE SAME INCIDENT, SPILLING ABOUT A GALLON OF FUEL! I CALLED AGAIN AND SAID IT WAS BAD FUEL? NOW, IN APRIL 2010 WITH THE WEATHER BEING WARM & WHEN I TURN ON THE VEHICLE THE EXHAUST PIPES BEGIN TO SMOKE AND YOU CAN FIND GUNK INSIDE THE EXHAUST PIPES. I WILL BE SOON BE CALLING GORMAN MCCRAKEN IN LONGVIEW, TX FOR THEM TO LOOK AT THE VEHICLE AGAIN AS IT IS REPEATING EVERY PROBLEM ONCE AGAIN. *TR

MY WIFE AND I PURCHASED A 2007 MAZDA CX-7 FROM LITHIA MAZDA IN FRESNO, CA. IT WAS A BRAND NEW VEHICLE AND WITHIN THE FIRST 26,000 MILES, THE AIR CONDITIONING COMPRESSOR WENT OUT. THIS WAS COVERED UNDER THE FACTORY WARRANTY AND REPLACED. NOW MY THE SAME VEHICLE HAS 65,000 MILES ON IT AND THE COMPRESSOR WENT OUT AGAIN. I HAVE BEEN TOLD BY THE DEALERSHIP THAT THEY WILL REPLACE THE UNIT (FOR $1,800) AND WARRANTY IT FOR 3 YEARS OR 50,000 MILES. I FAIL TO COMPREHEND WHY THIS IS NOT ALREADY COVERED UNDER THE SAME WARRANTY. *TR
