2007 MAZDA CX-7 Engine And Engine Cooling Problems

TIMING CHAIN BROKE. *TR

I STARTED TO ACCELERATE AFTER COMING OFF OF AN EXIT RAMP WHEN I HEARD A NOISE FROM THE ENGINE THEN I STARTED TO LOSE POWER. IMMEDIATELY AFTER THAT WHEN I DEPRESSED THE GAS PEDAL TO ACCELERATE, A GRINDING NOISE OCCURRED. I WAS ABLE TO GET THE VEHICLE TO A PARKING LOT. I HAD THE CAR TOWED TO MAZDA DEALERSHIP WHO INFORMED ME THAT THE TURBO HAD FAILED. THEY WANT ALL MAINTENANCE RECORDS FOR THE TIME I HAVE OWNED THE CAR IN ORDER TO MAKE A DETERMINATION OF WHETHER IT WILL BE COVERED UNDER WARRANTY. I PURCHASED AN EXTENDED POWERTRAIN WARRANTY WHICH COVERS THE ENGINE AND TURBO TO 100,000. BUT IT APPEARS THEY ARE STATING IT IS DUE TO IMPROPER MAINTENANCE AS I CANNOT PRODUCE ALL MY OIL CHANGE RECEIPTS. *TR

TL* THE CONTACT OWNS A 2007 MAZDA CX-7. THE CONTACT STATED THAT THERE WAS AN ABNORMAL KNOCKING COULD BE HEARD HEAR FROM THE ENGINE WHEN FIRST STARTING THE VEHICLE. LATER, THE VEHICLE STALLED WHILE DRIVING AND WAS TAKEN TO A LOCAL MECHANIC. THE MECHANIC ADVISED THAT THE TIME BELT WAS FRACTURED AND THE ENGINE NEEDED TO BE REPLACED. THE CONTACT DID NOT CALL THE MANUFACTURER. THE FAILURE MILEAGE WAS 100,000.

THE AIR CONDITIONING COMPRESSOR ON THE VEHICLE SEIZED WITH NO WARNING & CAUSED THE SERPENTINE BELT TO CATCH ON FIRE. THIS APPEARS TO BE A KNOWN ISSUE WITH THIS VEHICLE, BASED ON MANY POSTINGS ON THE INTERNET. ADDITIONALLY, THE SERVICE MANAGER AT THE DEALER I TAKE MY VEHICLE TO FOR SERVICE SAID A NOISE GETTING PROGRESSIVELY LOUDER IN THE ENGINE IS THE TIMING CHAIN ADJUSTER THAT WILL REQUIRE REPLACEMENT VERY SOON. HE SAID THIS IS A KNOWN ISSUE WITH THIS PARTICULAR VEHICLE, AND THE MANY POSTINGS ON THE INTERNET ABOUT THE SAME ISSUE SEEM TO CONFIRM HIS STATEMENT. COMBINED, REPAIRS FOR BOTH WILL BE IN THE $3500 TO $5000 RANGE. *TR

THERE ARE TWO COMPLAINTS FOR THIS VEHICLE. 1. TIMING BELT...FAILURE AFTER 68,000 MILES CHANGED AFTER A DISPUTE WITH DEALERSHIP, WE STILL HAD TO PAY FOR 2 HRS OF LABOR. 2. TURBO UNIT...FAILURE AFTER 70,000 MILES STILL AT DEALERSHIP...NO OPTION BUT TO PAY $3083 TO GET FIXED. TURBO FAILURE HAPPENED ON HIGHWAY, VEHICLE PERFORMED ERRATIC AND LIMPED TO OFF RAMP USING SHOULDER. *TR

CAR SUDDENLY STALLED 3 HOURS AWAY FROM HOME; NO NOTICEABLE PERFORMANCE ISSUES / NOISE PRIOR. TOWED TO MECHANIC WHO DETERMINED TIMING BELT BROKE CAUSING SOME VALVES TO BEND AND OTHER DAMAGE THEREFORE REPLACEMENT OF ENGINE REQUIRED. WAS ON , OTHER CAR BLOG SITES ALONG WITH RESEARCHING THIS SITE AND FOUND THAT MANY, MANY OTHERS WHO HAVE ENCOUNTERED THE SAME ISSUE AROUND THE 60K MILES MARK (OR LESS IN SOME CASES). SPOKE TO MAZDA AND THEY ARE NOT TAKING ANY OWNERSHIP OR RESPONSIBILITY EVEN THOUGH MANY INCIDENCES OF THE SAME MECHANICAL PROBLEM. OIL CHANGES WERE MADE REGULARLY AND CAR WAS LAST INTO MAZDA FOR A NOISE LESS THAN A YEAR AGO WHICH THEY SAID WAS DUE TO MY BRAKES. HAVE OWNED MANY CARS BEFORE (NOT MAZDAS) AND THIS CAR IS A HUGE DISAPPOINTMENT AS IS MY EXPERIENCE WITH MAZDA. I HOPE THIS ISSUE WILL BE OR IS BEING PURSUED WITH MAZDA....

I HAVE HAD MY 2007 MAZDA CX-7 FOR LESS THAN ONE YEAR. I STOPPED AT A RED LIGHT AFTER EXITING THE HIGHWAY AND MY CAR ENGULFED IN THICK WHITE SMOKE. I HAD THE CAR TOWED TO A LOCAL SHOP PER MY INSURANCE COMPANY TO HAVE IT CHECKED OUT. THE REPAIR SHOP AT FIRST CALLED TO TELL ME IT WAS THE STARTER, AND THAT IT WOULD COST 600 TO FIX IT. COME TO FIND OUT THAT NOT ONLY THE STARTER BLEW, BUT IT ALSO RUINED THE ALTERNATOR AS WELL AS THE FUSES ON THE BATTERY. I WAS TOLD BY MAZDA THAT THIS IS NOT A COMMON OCCURRENCE. THE TOTAL OF THE REPAIRS IS NOW OVER 1200. THE VEHICLE HAS BEEN METICULOUSLY MAINTAINED THROUGHOUT ITS LIFESPAN AND IS AT 92,000 MILES. *TR

AFTER DRIVING DOWN THE EXPRESSWAY THE AIR CONDITIONER STOPPED WORKING. I BROUGHT IT TO THE MECHANIC AND WAS TOLD THE AIR COMPRESSOR KIT WENT OUT AND IT IS $2,300 TO FIX. *TR

TL* THE CONTACT OWNS A 2007 MAZDA CX-7. THE CONTACT STATED THAT THE ENGINE WAS STARTED AND A RATTLING NOISE WAS HEARD FROM THE ENGINE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE DEALER CONFIRMED THAT THE VARIABLE VALVE TIMING ACTUATOR FAILED AND WOULD NEED REPLACING. THE MANUFACTURER WAS NOT CONTACTED AND THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 69,000. THE TIMING CHAIN AND BELT WAS REPLACED. UPDATED 11/10/2011 *LN

2007 MAZDA CX7 - TURBO BROKE WHILE DRIVING CAUSING TREMENDOUS SQUEALING SOUND AND LOSS OF POWER. ABLE TO DRIVE HOME AND HAD TOWED TO MAZDA DEALERSHIP. SERVICE MGR CALLED ME SAYING THEY CHECKED CAR OVER AND COULD NOT FIND ANYTHING WRONG WITH IT AND ASKED IF I WANTED AN OIL CHANGE. I SAID GO AHEAD WITH AN OIL CHANGE BUT THERE IS DEFINITELY SOMETHING WRONG WITH CAR AND TO CHECK AGAIN. MGR CALLED BACK LATER SAYING A SCREW IN THE TURBO HAD COME LOOSE, TURBO WAS BROKEN, I NEEDED A WHOLE NEW ENGINE AND IT WOULD COST $9,000. CAR HAD 34,000 MILES AND STILL UNDER WARRANTY. I FAX'D COPIES OF OIL CHANGE RECEIPTS. MAZDA NORTH AMERICA DENIED WARRANTY CLAIM SAYING MY OIL RECEIPTS WERE UNVERIFIABLE. MNA TOLD ME THEY WOULD NOT VERIFY MY RECEIPTS. THEY CLAIMED THERE WAS "SLUDGE" AND THAT CAUSED IT TO BREAK AND I HADN'T TAKEN CARE...

TIMING CHAIN AND VARIABLE VALVE TIMING MODULE FAILURE ON 2007 MAZDA CX-7. *TR

TL* THE CONTACT OWNS A 2007 MAZDA CX-7. THE CONTACT STATED WHEN TRYING TO START THE VEHICLE IT FAILED TO START ON AN INTERMITTENT BASIS. THE VEHICLE WAS TAKEN TO A DEALER WHO ADVISED HIM THAT THEY WERE UNABLE TO DIAGNOSE THE FAILURE OR DUPLICATE IT. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED AND OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS UNKNOWN AND THE CURRENT MILEAGE WAS APPROXIMATELY 26,000.

7/6/10(25,000 MILES) DRIVING "PIECE OF CRAP" FROM W-PA TO PHILA AFTER 1 1/2 HOURS IN CAR AIRCONDITIONING GETS HOT & LOUD NOISE STARTS. ABLE TO PULL OFF MAIN HIGHWAY &FIND A SEARS AUTO SHOP THEY SAY AIR COMPRESSOR IN MY PICE OF CRAP (2007 CX7) HAS FALLEN APART - THEY DON'T DO THIS WORK-I NEEDED A MAZDA DEALERSHIP-THEY WOULDN'T RECOMMEND ME DRIVING HOME! IT'S A HOLIDAY (JULY 4TH CELEBRATED THIS DAY) I HAVE NO IDEA WHERE A DEALERSHIP IS-I AM OVER 200 MILES FROM HOME - EVERYTHING ELSE IS CLOSED. FOUND A HOTEL TO STAY OVERNT & SEARCH FOR A DEALERSHIP. FOUND 1 ABT 20 MILES AWAY. NEXT DAY (PRAYING THE WHOLE 20 MILES) THAT PIECE OF CRAP WOULD MAKE IT TO THE SHOP. IT DID I EXPLAIN SITUATION TO A NON-CARING, WON'T LOOK ME IN THE FACE MECHANIC WHO FINALLY STATES (AFTER 3 HOUR WAIT) MY WARRANTY EXPIRED 5...

DRIVING ON THE FREEWAY 65 MILES PER HOUR, ENGINE SHUT OFF... PULLED TO SIDE OF ROAD. CAR TOWED TO MECHANIC. DIAGNOSTIC WITH TWO QUOTES TIMING CHAIN SNAPPED BENT VALVE, NEED TO REPLACE THE ENGINE. I HAVE BEEN REVIEWING FORUMS AND HAVE FOUND THIS IS AN ISSUE WITH HUNDREDS OF MAZDA CX7 2007 MODELS. MY CAR IS AT THE 61,000 MILES MARK. IF SO MANY PEOPLE ARE HAVING THE EXACT SAME ISSUE ITS NO COINCIDENCE, THANKFULLY ON THE DAY MY ENGINE SHUT DOWN WAS IN THE FAR LANE THAT I COULD PULL OVER. SOMEONE ELSE WITH THIS CAR MIGHT NOT BE SO LUCKY. MAZDA NEEDS TO RECALL AND START DOING SOMETHING. *TR

(MARCH/2011) LIGHT CAME ON AROUND 65K MILES. TOOK IT INTO DEALERSHIP AND THEY SAID OIL WAS LOW AND YVT NEEDED REPLACING. COST WAS AROUND 2500. NO REASON WHY OIL WAS LOW AND LAST CHANGED BY MAZDA LESS THAN 7500 MILES BEFORE. ALSO FULL SERVICE WAS DONE AT THAT TIME. (JUNE/2011)WHILE ON HIGHWAY AT HIGH SPEEDS THE CAR LOST ACCELERATION, EMITTED HIGH PITCH WHIRRING. AND BECAME DIFFICULT TO CONTROL. TOWED TO DEALERSHIP AND IT IS BEING BLAMED ON BAD TURBO. NO REASONING BEHIND FAILURE OTHER THAN SAYING OIL CHANGE ISSUES. THE PROBLEM IS THAT MAZDA IS THE ONLY ENTITY THAT HAS EVER WORKED ON THIS CAR AT LEAST TWICE PER YEAR FOR CHECK UPS. THERE ALSO APPEARS TO BE OTHERS WITH SAME REPORTED PROBLEMS TO BOTH TURBO AND YVT. *TR

2007 MAZDA CX-7 AWD GRAND TOURING WITH 39K MILES. CAR WAS BEING DRIVEN HAD SUDDEN LOSS OF POWER WHILE TRAVELING DOWN ROAD. IN TRAFFIC CAR SUDDENLY SLOWED TO CRAWL AT 20MPH ONCE CAR WAS NAVIGATED TO SHOULDER AND STOPPED IT WOULD NOT RESTART. THE VEHICLE WAS TOWED TO DEALERSHIP WHERE THEY HAVE STATED THAT THE TIMING CHAIN OR VVT HAS FAILED RESULTING IN TIMING CHAIN FAILURE THUS TOTAL ENGINE FAILURE. KNOWN PROBLEM REPORTED NUMEROUS TIMES AND YET MAZDA DEALERSHIP HAS INFORMED ME THAT WITH THE MAINTENANCE RECORDS PROVIDED THEY ARE REFUSING REPAIR. THESE TIMING CHAINS ARE FAILING ON CARS WITH 19K-60K MILES, NOT WITHIN NORMAL MAINTENANCE. *TR

2007 GRAND TOURING MAZDA CX-7 HAS WELL KNOWN VVT ISSUE CAUSING OIL TO BURN, IN SPITE OF REGULAR OIL CHANGES AND ALL RECOMMENDED MAINTENANCE. WE ARE ORIGINAL OWNERS AND KNOW HOW CAR WAS MAINTAINED . TIMING CHAIN WENT AT 62K MILES, JUST OUT OF WARRANTY. AFTER THAT SERVICE, DROVE 1K MORE MILES AND NOTICED LOSS OF ACCELERATION. TOOK CAR BACK TO DEALER, AND THEY ADVISED WE NEEDED A WHOLE NEW ENGINE, WHICH THEY WOULD NOT COVER, ASIDE FROM A 20% GOODWILL OFFSET. SPOUSE WON'T LET ME OPERATE CAR ANY LONGER IN FEAR IT WILL BREAK DOWN CAUSING ACCIDENT. UNSAFE VEHICLE.

A/C COMPRESSOR DIED. *TR

TL* THE CONTACT OWNS A 2007 MAZDA CX7. THE CONTACT STATED WAS DRIVING 55 MPH WHEN THE ENGINE OIL SHIELD COVER SEPARATED FROM THE VEHICLE. THE CONTACT STATED THAT THE VEHICLE WITH THE DEALER ONE DAY PRIOR TO THE FAILURE FOR ROUTINE OIL CHANGE. THE VEHICLE WAS TAKEN BACK TO THE DEALER WHO PERFORMED A DIAGNOSTIC AND LOCATED THE FAILURE AT THE ENGINE OIL PLASTIC SHIELD COVER. THE DEALER ADVISED THAT THERE WAS A POSSIBILITY THAT THE SCREWS MAY NOT HAVE BEEN PLACED BACK CORRECTLY. THE DEALER REPLACED THE OIL COVER SHIELD WITH THE SAME DEFECTED PLASTIC AND THERE WERE NO FURTHER REPAIRS. THE FAILURE AND THE CURRENT MILEAGE WAS 70,000.

I OWN A 2007 MAZDA CX7. SINCE I BOUGHT THE CAR, AT 29K MILES I HAD TO HAVE THE FUEL TANK REPLACED. AT AROUND 34K HAD TO HAVE THE TURBO LOOKED AT BECAUSE OF BLACK SMOKE BLOWING ON MY BUMPER, MAZDA REPLACED THE PIPES. MY PIPES WERE STILL SMOKING, HAD TO TAKE OFF WORK, TAKE CAR IN AGAIN BECAUSE OF BLACK SMOKE, MAZDA TRIED REPLACING RINGS IN TURBO, STILL BLOWIN BLUISH WHITE SMOKE, NOW GETTING TURBO REPLACED. I HAD THE AIR COMPRESSOR REPLACED A ABOUT A MONTH AGO. NOW I HAVE A TICKING NOISE COMING FROM ENGINE AND I'M SCARED THE TIMING CHAIN WILL BREAK SOON. MAZDA NEEDS TO REPLACE THE TIMING CHAINS ON THESE MODELS. I THINK MAZDA SHOULD DO THE RIGHT THING AN RECALL THIS MODEL, YR BEFORE SOMEONE GETS HURT OR BREAKS DOWN IN THE MIDDLE OF NOWHERE WITH KIDS IN THE CAR. *TR

MY 2007 MAZDA CX-7 AIR CONDITIONER COMPRESSOR LOCKED UP CAUSING MINOR ACCIDENT FROM UNDRIVEABILITY.*TR

IN APRIL 2009 THE AIR CONDITIONER COMPRESSOR FAILED ON MY 2007 MAZDA CX-7. THERE WAS APPROXIMATELY 49,000 MILES ON THE CAR WHEN THIS HAPPENED. WE REPLACED THE COMPRESSOR WITH AN AFTERMARKET COMPRESSOR BECAUSE THE DEALER INDICATED IT WAS NOT IN WARRANTY. SOME TIME LATER WE RECEIVED A LETTER FROM MAZDA EXTENDING THE WARRANTY ON THE COMPRESSOR TO 60,000 MILES. IN THE LETTER MAZDA EXPLAINED THAT IF THE COMPRESSOR HAD ALREADY BEEN CHANGED THEY WOULD REIMBURSE US FOR THE CHARGES. THE PAPERWORK HAD BEEN MISPLACED AT THE TIME SO WE DID NOT CONTACT MAZDA FOR REIMBURSEMENT. IN DECEMBER 2010 MY DAUGHTER WAS DRIVING THE CAR IN DALLAS TEXAS WHEN SHE HEARD A NOISE COMING FROM UNDER THE HOOD. A BURNING SMELL STARTED COMING THROUGH THE VENTS, THEN SMOKE STARTED COMING INTO THE CAR, SHE HAD TO CROSS THREE LANES OF TRAFFIC TO GET OFF OF THE ROAD. THE CAR STOPPED RUNNING...

COMPLETE ENGINE FAILURE WITHOUT WARNING WHILE TRAVELING 70 M.P.H DOWN 40 EAST XMAS EVE EVENING. I PRAYED MY CHILD AND I WOULDN'T END UP DEAD WHILE TRYING TO CUT ACROSS TWO LANES TO GET OFF THE ROAD IN MY VEHICLE WITHOUT ENGINE POWER. *TR

AN EXCESS OF WHITE SMOKE EMITTED FROM EXHAUST UPON ACCELERATION AFTER A BRIEF PERIOD OF IDLE. IT WAS DETERMINED THAT A FAULTY TURBO CHARGER WAS TO BLAME. SO THE CAR WAS IN THE SHOP FOR 7 DAYS WHILE THEY REPLACED THE TURBO. SEVERAL MONTHS LATER THE CAR WOULDN'T START AFTER SITTING IN A HEATED GARAGE OVERNIGHT. IT SOUNDED AS THOUGH THE CYLINDERS WEREN'T FIRING PROPERLY. CAR WAS TOWED TO MECHANIC WHO IDENTIFIED ISSUE AS FOULED CYLINDER HEADS FROM PRIOR FAILURE OF TURBO. THIS TIME THE ENTIRE ENGINE WAS REPLACED. AGAIN THE CAR WAS IN THE SHOP FOR APPROXIMATELY SEVEN DAYS. SOME MONTHS LATER AN OPPRESSIVE AMOUNT OF ROAD NOISE APPEARED AT ALL SPEEDS ON ALL ROAD SURFACES. WE WERE DIRECTED THAT THE TIRES WERE TO BLAME. AFTER REPLACING ALL 4 TIRES AT A COST OF NEARLY $800 THE SOUND PERSISTED. UPON FURTHER INSPECTION THE TECHNICIAN FOUND THAT THE WHEEL SPEED...

MY WIFE'S 2007 CX7 WAS IN A PARKING LOT. MY WIFE STARTED IT UP, CAME TO A STOP SIGN AND THE CAR DIED WITHOUT WARNING. IT HAD 65,000 MILES ON IT (5000 OVER THE WARRANTY) AND WASN'T EVEN 3 YEARS OLD. WE HAD ALWAYS GOTTEN REGULAR OIL CHANGES AND HAD JUST HAD ONE THE WEEK BEFORE. WE HAD IT TOWED TO THE NEAREST MAZDA DEALER. THE FIRST TIME I TALKED TO A SERVICE TECH HE MENTIONED THE TIMING CHAIN BREAKING. LATER, THEY EXPLAINED IT AS A VALVE (VARIABLE VALVE TIMING ACTUATOR?) FAILING AND CAUSING OIL CHAIN FAILURE (JUMPING THE GEARING). MY BILL ($7500 - NEW ENGINE) ONLY STATES INTERNAL PARTS FAILURE. THEY TRIED TO INDICATE THE OIL WAS DIRTY EVEN THOUGHT THE OIL WAS CHANGED LESS THAN A WEEK PRIOR. AFTER READING THROUGH MANY CX7 FORUMS ONLINE IT SEEMS THEY WERE TRYING TO BUILD A CASE FOR ENGINE SLUDGE TO...

FILE # 132495780. MAZDA REPRESENTATIVE ASKED TO TOW THE CAR TO A MAZDA DEALER FOR DIAGNOSTICS, AND MAZDA WILL SEND A FIELD MANAGER TO DETERMINE IF THE ENGINE FAILURE IS DUE TO MANUFACTURER DEFECT OR NOT. MAZDA MAY BE WILLING TO OFFER AFTER WARRANTY ASSISTANCE IN THE COST OF THE REPAIR OR EVEN COVER THE ENTIRE COST. CAR WAS TOWED TO A MAZDA DEALER ON 10/28/10 AM. AT 5 PM SAME DAY, DEALER CALLED MY WIFE AND SAID THAT THE CAR NEEDS A NEW ENGINE AND IT WILL COST $8000 + TO FIX IT, AND THE MAZDA CORP FIELD MANAGER SAID THAT BASED ON THE MAINTENANCE RECORD AND MILEAGE, MAZDA CORP WILL NOT OFFER ANY ASSISTANCE. I WAS...

TL*THE CONTACT OWNS A 2007 MAZDA CX7. THE CONTACT STATED THAT THE VEHICLE WAS TAKEN TO THE DEALER FOR ANOTHER REPAIR AND ALSO INFORMED THE DEALER THAT IT WAS MAKING A NOISE. THE DEALER REPLACED THE VVT ACTUATOR AT THAT TIME. THE VEHICLE WAS TAKEN BACK TO THE DEALER BECAUSE THE CONTACT NOTICED THAT THE FAILURE CONTINUED. THE DEALER STATED THAT THE AIR CONDITIONER COMPRESSOR WAS THE CAUSE OF THE FAILURE. AFTER TWO DAYS, WHILE DRIVING THE CONTACT NOTICED THE NOISE AGAIN SO THE VEHICLE WAS TAKEN BACK TO THE DEALER; THE DEALER REPLACED THE SERPENTINE BELT AND PULLEY SYSTEM. THE FAILURE CONTINUED, THE NOISE WORSENED AND THE VEHICLE LOST MOMENTUM WHILE SHE WAS DRIVING; THE DEALER THEN STATED THAT SHE NEEDED A NEW ENGINE, NEW TURBO, NEW PULLEY AND VVT ACTUATOR. THE VEHICLE HAD NOT BEEN REPAIRED. THE CONTACT CALLED THE MANUFACTURER WHO ASKED THAT SHE SUBMIT MAINTENANCE RECORDS...

I OWN A 2007 MAZDA CX7 AND IT WAS BEEN AT THE DEALER EVERY MONTH THIS SUMMER AND I'M ON MY SECOND LONER CAR. THE TROUBLE STARTED LAST SUMMER WITH PINGING AND TURBO LAG. THAT SEEMED TO STOP AND THE DEALER SAID THAT IT WAS A SOFTWARE ISSUE. BUT THIS SUMMER WE HAVE HAD THREE SEPARATE ISSUES. 1. TRANSFER CASE LEAK. FIXED. 2. ENGINE STABILIZER LEAK. FIXED. 3. VARIABLE VALVE TIMING ACTUATOR VVTA. CURRENTLY IN SHOP. CAR LOUDLY "GROWLS" TO LIFE, SQUEAKY BELT, DIFFICULTY STARTING, TOLD BY DEALER THAT WILL EVENTUALLY CAUSE ENGINE TROUBLE IF NOT FIXED. THIS HAS ALL BEEN SINCE JULY!!! WE ARE JUST SHY OF 30K AND THE WARRANTY EXPIRES NEXT MONTH. I AM VERY AFRAID THAT SOMETHING ELSE WILL GO WRONG AND WE WILL END UP PAYING FOR IT. UPON READING A FEW CX7 WEB SITES AND BLOGS, IT HAS BECOME CLEAR THAT THIS VVTA ISSUE...

THE TIMING CHAIN IS MESSED UP ON MY 2007 MAZDA CX-7 IT ONLY HAS 85K MILES ON IT. *TR

OUR 2007 CX-7 MAZDA DEVELOPED NOISE. WE RECEIVED LETTER FROM DEALERSHIP REGARDING POSSIBLE NEED TO FIX AC COMPRESSOR. ABOUT 10 DAYS LATER ON SEPT.5 2010 WE TOOK A TRIP AND DID NOT TURN ON THE AC BUT A LOUD NOISE DEVELOPED AND WE LOST ACCELERATION ABILITY. NO WARNING LIGHT EVER CAME ON. OUR CAR HAS ABOUT 40,000 MILES ON IT. TOWED IT TO MAZDA DEALERSHILP. THEY SAID THEY COULDN'T TELL WHAT WAS WRONG. SEVERAL DAYS LATER THEY SAID THE TURBO HAD FAILED AND THE ENGINE IS RUINED AND WOULD NEED REPLACING. THEY SAID THAT THE ENGINE HAD NO OIL (REMEMBER, NO WARNING LIGHT) AND THEY FOUND SLUDGE, INDICATING NEGLECT. WE HAVE HAD OIL CHANGES AS REQUIRED. THEY HAVE NOT AGREED TO FIX IT. WE HAVE FOUND NUMEROUS OTHER OWNERS OF SAME MODEL AND YEAR ONLINE ON EDMUNDS.COM. IT SEEMS TO BE A PROBLEM FOR THIS PARTICULAR MODEL AND YEAR AND...

2007 MAZDA CX-7 TIMING CHAIN ISSUE THAT NEEDS TO BE REPLACED FOR FREE. THE WARRANTY COMPANY IS TRYING TO NOT PAY THE CLAIM. I WAS DRIVING 20MPH AND MY CAR DIED. IT WAS TOWED TO THE DEALERSHIP. THEY SAID THIS NEVER HAPPENS. I HAVE GOTTEN ALL OF THE OIL CHANGED IN MY CAR WHEN IT NEEDED TO BE AND THEY ARE TRYING TO SAY THAT I DID SOMETHING TO THE VEHICLE. I'M 42 YEARS OLD AND PAID ALOT OF MONEY FOR THIS VEHICLE. I DO KNOW HOW TO TAKE CARE OF IT. *TR

WHILE NORMAL DRIVING, THE 2007 MAZDA CX-7 STOPPED RUNNING. IT WAS TOWED TO THE LOCAL MAZDA DEALERSHIP (SAN ANTONIO, TX). UPON FURTHER INVESTIGATION, THE CONSUMER WAS INFORMED THAT A NEW ENGINE WAS REQUIRED DUE TO EXCESSIVE SLUDGE BUILD-UP IN THE ENGINE. ADDITIONALLY, THE CONSUMER WAS TOLD THAT THIS REPAIR WOULD NOT BE COVERED BY THE WARRANTY DUE TO LACK OF REQUIRED MAINTENANCE RESULTING IN SLUDGE BUILD-UP. THE VEHICLE WAS MAINTAINED IN ACCORDANCE WITH THE OWNERS MANUAL, BUT THE CONSUMER WAS TOLD APPROX. $7000.00 FOR AN ENGINE REPLACEMENT. *TR

MAZDA CX-7 WITH LESS THAN 90,000 HAS ENGINE LIGHT ON DUE TO BAD VARIABLE ACTUATOR FOR THE ENGINE AND BAD OIL CONTROL VALVE. I HAVE HAD REGULAR OIL CHANGES AND MAINTENANCE. THE COST OF REPAIR IS $1700. LAST YEAR I SPENT $3000.00 DUE TO AIR CONDITIONER AND OTHER PROBLEMS WITH THE CAR WITH LESS THAN 60,000. *TR

MY MAZDA 2007 CX7 STALLED ON ME AND THEN DIED ON THE SIDE OF THE ROAD. I HAD IT TOWED TO THE DEALERSHIP AND ON MONDAY THEY TOLD ME THE OIL WAS LOW AND I NEEDED A NEW ENGINE. I MAINTAIN MY CAR AS REQUIRED AND THERE WERE NO SIGNALS INDICATING MY OIL OR ANYTHING ELSE WAS NOT WORKING PROPERLY. I BOUGHT THIS CAR BRAND NEW IN 2007 AND THIS IS THE FIRST MAJOR INCIDENT I HAVE EVER HAD. THE DEALERSHIP DID NOT GIVE ANY OTHER OPTIONS BUT TO BUY A NEW ENGINE FOR 6,400.00. I WAS TOLD THAT MY WARRANTY EXPIRED AT 60,000 MILES. *TR

I RECENTLY BOUGHT A USED MAZDA CX-7 GRAND TOURING EDITION VEHICLE. I BOUGHT IT ON NOVEMBER 8, 2008 WITH 18,000 MILES ON IT. AFTER OWNING IT FOR A YEAR AND A HALF I WAS DRIVING TO WORK ONE MORNING WHEN I HEARD A POP AND CLANKING SOUND. I CONTINUED TO DRIVE UNTIL MY CAR STARTED LOSING POWER HOWEVER I MANAGED TO MAKE IT TO WORK. NO LIGHTS CAME ON, NOTHING. MY HUSBAND CAME THAT MORNING TO DRIVE THE CAR TO THE MECHANIC AND WITHIN 2 MILES ALL THE DASH LIGHTS CAME ON AND THE CAR LOST ALL POWER. IT WAS TOWED TO GRAPPONE MAZDA IN CONCORD NH FOR WHAT I THOUGHT WOULD BE WARRANTY WORK SINCE WE WERE STILL UNDER THE WARRANTY. WE WERE TOLD TO PRODUCE ALL SERVICE RECORDS WHICH WE DID, AND THEY FOUND SOME GAPS, HOWEVER, NEVER OVER THE RECOMMENDED 7500 MILES THAT THEY RECOMMEND FOR AN...

DRIVING HOME FROM WORK DURING RUSH HOUR. SMOKE BEGAN POURING OUT OF ENGINE COMPARTMENT OUTSIDE VEHICLE AND INTO THE CABIN. FEARING AN ENGINE FIRE, PULLED OFF TO LEFT SHOULDER OF HIGHWAY AND SHUT OFF ENGINE. OPENED HOOD (WITH MUCH TREPIDATION) TO OBSERVE PROBLEM. SMOKE CONTINUED TO EMANATE FROM PASSENGER SIDE OF ENGINE COMPARTMENT NEAR SERPENTINE BELTS - NO OBVIOUS FIRE. LET VEHICLE SIT FOR 5 MINUTES AND RESTARTED - SAME PROBLEM. SHUT OFF A/C, AND SMOKE AND NOISE DISCONTINUED. IDLED FOR 5 MINUTES - NO MORE APPARENT PROBLEMS WITH A/C OFF. PULLED BACK ON TO HIGHWAY AND CONTINUED TRIP HOME. DID SOME ONLINE INVESTIGATION AND DEDUCED THAT A/C COMPRESSOR HAD SEIZED. ANECDOTAL EVIDENCE OF WIDESPREAD PROBLEM, INCLUDING CATASTROPHIC FAILURES FOR OTHER MAZDA CX7 OWNERS. ANECDOTAL EVIDENCE OF A COMPLETE COMPONENT REDESIGN FOR 2008 MODEL YEAR. BROUGHT CAR TO DEALER FOLLOWING MONDAY - A/C COMPRESSOR HAD SEIZED AND REQUIRED REPLACEMENT TO...

2007 MAZDA CX-7 GRAND TOURING. (FAMILY CAR)! 43,636 MILES(OUT OF WARRANTY) FIRST OFF, MY WIFE AND I HAVE A HAD OUR CAR SERVICED AND OIL CHANGED EVERY 3000 MILES! AND WE HAVE TAKEN THE CAR IN NUMEROUS TIMES FOR THE A/C NOT WORKING IN OVER 90 DEGREES TEMPERATURES. AND HAVE BEEN TOLD BY 2 DEALERSHIPS THAT THE CX-7'S A/C DOESN'T WORK WELL OVER 90 DEGREES. LIVING IN SOUTHERN CALIFORNIA ITS OVER 90 DEGREES FOR ALMOST 6 MONTHS OF THE YEAR. A COUPLE DAYS AGO, MY WIFE, YOUNG DAUGHTERS AND I WERE DRIVING OUR CAR TO A DESTINATION ONLY 3 MILES FROM HOME. (THE CAR HAD BEEN SITTING ALL DAY, IN THE GARAGE.) WE HAD THE A/C ON HALF WAY(85 DEGREES OUT). ABOUT READY TO GET OFF THE FREEWAY AND ONLY GOING 60 MPH. THE AIR BLOWING OUT OF THE A/C STARTED BLOWING HOT, EASILY OVER 100 DEGREES. THE A/C STARTED...

HAVE A 2007 CX7 WITH 34,000 MILES ON IT. IT WAS PURCHASED IN SEPT OF 09 AT A MAZDA DEALERSHIP USED. UPON EXITING THE INTERSTATE, AT THE BOTTOM OF THE RAMP THE CAR STALLED JUST AS THE LIGHT TURNED GREEN. THE CAR AND SEMI BEHIND ME ALMOST CRASHED INTO ME.. I PUT IT IN PARK AND IT STARTED UP. I GOT ABOUT 2 BLOCKS DOWN THE ROAD AND WAS SITTING AT THE LIGHT WHEN I NOTICED WHITE SMOKE COMING FROM THE PASSENGER ENGINE COMPARTMENT. ENGINE TEMPS WERE FINE BUT YOU COULD SMELL BURNT RUBBER. I PULLED INTO A GAS STATION AND LIFTED THE HOOD. I COULD TELL THE A\C COMPRESSOR WAS NOT TURNING SO I TURNED THE A\C OFF AND MADE IT TO MY DESTINATION ABOUT 3 MILES LATER.I TOOK THE CAR INTO MAZDA TODAY ONLY TO FIND OUT THE 36 MONTH TIME PERIOD HAD EXPIRED ON 2/20/2010. THE TECH...

WHILE DRIVING WITH FAMILY, AIR CONDITIONER SUDDENLY STARTED BLOWING WARM AIR. ALL ATTEMPTS FAILED TO ADJUST AIR CONDITIONING. THIS FAILURE HAS ONLY HAPPENED ONCE BUT IS STILL NOT OPERATING PROPERLY. WHEN THE VEHICLE WAS STARTED THE NEXT DAY IT BEGAN MAKING A GRINDING NOISE. THE SUSPECTED DEFECT IS THE A/C COMPRESSOR, IT HAS NOT BEEN REPAIRED OR REPLACED. *TR

DRIVING ON FREEWAY AND A/C BEGAN TO BLOW HOT. SMOKE AND BURNT RUBBER SMELL COMING FROM UNDER HOOD. LOST POWER STEERING ASSIST BUT WAS STILL ABLE TO BARELY STEER VEHICLE TO SIDE OF FREEWAY. HAD VEHICLE TOWED TO SHOP. A/C COMPRESSOR LOCKED UP AND DESTROYED DRIVE BELT. HAD COMPRESSOR REPLACED AND IT FAILED 20 MILES LATER, BEFORE I EVEN GOT HOME. HAVE TO REPLACE IT AGAIN. COMPRESSOR FAILURE IS A SAFETY HAZARD DUE TO THE LOSS OF POWER STEERING. *TR

2007 MAZDA CX-7 STARTED MAKING A GRINDING SOUND FROM UNDERNEATH THE HOOD, WITH SMOKE BELLOWING FROM THE ENGINE. COME TO FIND OUT THAT THE A/C PUMP AND OR COMPRESSOR HAS SUDDENLY SEIZED CAUSING MAJOR DAMAGE TO THE ENGINE AND VEHICLE ITSELF. *TR

MY WIFE AND I PURCHASED A 2007 MAZDA CX-7 A FEW YEARS AGO, AND OVER THE LAST THREE MONTHS IT HAS BEEN IN THE SHOP WITH MULTIPLE PROBLEMS. FROM AN OIL LEAK, TO A BAD COMPRESSOR, THEN THE TIMING CHAIN GONE BAD AND NOW ANOTHER PROBLEM WITH THE EGR. THE CAR HAS A LITTLE OVER 38K MILES AND TO ME IT SEEMS VERY ODD FOR A CAR BEING THIS YOUNG IN MILES, TO HAVE MAJOR PROBLEMS SUCH AS THESE. AFTER GOING BACK AND FORTH WITH THE MAZDA CORPORATE OFFICE, THEY FIRST AGREED TO PAY FOR THE PARTS FOR MY LATEST PROBLEMS SINCE I'M NOW OUT OF WARRANTY. I WAS FINE WITH THAT UNTIL I FOUND OUT THE LABOR WAS OVER $500 TO FIX THIS PROBLEM. WHEN I CALL THE CORPORATE OFFICE TO TRY TO DISCUSS SPLITTING THE LABOR COSTS, THEIR SUPERVISOR CONTACTED ME BACK WITH AN ATTITUDE LIKE I DID...

WHILE DRIVING AT NIGHT AT HIGHWAY SPEED, NOISE STARTED TO COME FROM ENGINE COMPARTMENT. SEEMED TO COME AND GO, BUT SUDDENLY SMELLED SMOKE AND LOST POWER STEERING. NEARLY HAD A HEAD ON COLLISION. THIS WAS A VERY SERIOUS NEAR MISS. MANAGED TO GET CAR TO NEIGHBORHOOD CAR REPAIR SHOP. AFTER INSPECTION, CAUSE WAS DETERMINED TO BE SEIZED A/C COMPRESSOR THAT LED TO CASCADING FAILURES. COST TO REPAIR ALL DAMAGE WAS $2250. I HAVE SINCE READ THAT THIS IS A COMMON FAILURE ON MAZDA CX-7 AND STILL NO RECALL? I WILL BE SENDING A CLAIM TO MAZDA USA AND WOULD ALSO BE INTERESTED IN JOINING ANY CLASS ACTION SUITE TO RECOUPE ALL MY COSTS AND TO FORCE MAZDA USA TO MAKE A RECALL. FAMILY'S LIVES ARE AT STAKE. *TR

WHILE DRIVING WE HEARD A NOISE FROM THE ENGINE, WE WERE ABOUT A MILE FROM OUR DESTINATION. WHEN WE PULLED INTO THE PARKING LOT WE SAW SMOKE COMING FROM THE ENGINE COMPARTMENT. WHEN MY HUSBAND OPENED THE HOOD, WE SAW FLAMES. WE IMMEDIATELY CALLED 911 AND RAN TO THE BUILDING TO PROCURE A FIRE EXTINGUSHER. WE WERE ABLE TO LOCATE ONE AND MY HUSBAND PUT OUT THE FIRE. WE WERE TOLD BY THE MAZDA DEALERSHIP THAT THE COMPRESSOR CLUTCH HAD FAILED, CAUSING THE FIRE. WE HAD PURCHASED AN EXTENDED WARRANTY ON THE VEHICLE, UNFORTUNATELY, IT ONLY COVERED TO 60,000 MILES AND THE VEHICLE HAD 61,000 MILES. THE SERVICE MANAGER SUGGESTED THAT WE SHOULD FILE A CLAIM ON OUR INSURANCE, BUT SINCE WE HAVEN'T BEEN ABLE TO GET A DETAILED ESTIMATE ON THE DAMAGES, WE HAVEN'T PROCEEDED THAT FAR YET. THEY HAVE HAD THE VEHICLE FOR THREE DAYS AND THERE IS...

CAR'S A/C STOPPED WORKING AND SMOKE CAME FROM THE ENGINE. THEN THE CAR STALLED AND THE CONTROL VIA POWER STEERING WENT NON-EXISTENT. *TR

I GOT INTO A MAZDA FORUM WHERE MANY COSTUMERS ARE HAVING PROBLEMS WITH THE AIR CONDITIONING CLUTCH FAILURE (SEIZED) LOOSING POWER STEERING WHILE DRIVING. TURBO FAILURE, CAUSING ENGINE OVERHEATING. TIMING BELT FAILURE. I CAN NOT FIND ANY RECALLS ABOUT THESE FAILURES. *TR

MY WIFE WAS DRIVING HER 2007 MAZDA CX-7 WHEN SHE HEARD A BANG AND SMOKE STARTED BILLOWING FROM UNDER THE HOOD. SHE PULLED OVER AND TURNED OFF THE CAR. AFTER INSPECTION, I DETERMINED IT WAS THE AC COMPRESSOR BECAUSE IT WOULDN'T SMOKE WHEN THE AC WAS TURNED OFF. WE TOOK THE CAR TO THE DEALER AND THEY CONFIRMED MY SUSPICION. THE AIR COMPRESSOR HAD LOCKED UP AND NEEDED TO BE REPLACED AS WELL AS THE BELT. THIS WAS GOING TO COST $1069 PLUS TAX. AFTER READING OVER 15 PAGES OF SIMILAR COMPLAINTS ON EDMUND'S FORUM, I AM FILING A COMPLAINT. IT APPEARS THAT MY WIFE ONLY HAD A MINOR INCIDENT WHILE OTHERS LOST POWER STEERING AND COMPLETE OPERATION OF THEIR VEHICLE. THIS ISSUE DEFINITELY NEEDS TO BE RECALLED AS THIS IS HAPPENING TO MANY VEHICLES AND MAY COST SOMEONE'S LIFE. *TR

WE OWN A 2007 MAZDA CX7. WE TOOK A VACATION TO FLORIDA FROM OHIO. ON THE WAY BACK, WE BEGAN TO SMELL BURNING RUBBER. I STOPPED TO CHECK IT OUT, BUT EVERYTHING LOOKED TO BE IN ORDER AND NOTHING WAS LEAKING. WE THEN LOST AIR CONDITIONING AND THE SMELL BECAME MORE PREVALENT. MINUTES LATER, THERE WAS A LOUD BANG FROM UNDER THE HOOD. THE CAR BASICALLY BEGAN SHUTTING DOWN. ALL CHECK ENGINE LIGHTS CAME ON. SMOKE FROM UNDER THE HOOK. NO POWER STEERING. THIS HAPPENED AT 1AM IN THE HILLS OF WEST VIRGINIA, AND WE WERE LUCKY TO COAST INTO A MOTEL. THIS LEFT US STRANDED AT THE MOTEL, AND UPON OPENING MY HOOD - THERE WAS COOLANT ALL OVER THE ENGINE BAY AND THERE WERE SHREDS OF RUBBER FROM THE BELTS THAT HAD SNAPPED OFF. THE SHREDDED BELTS WERE STILL SITTING INSIDE THE ENGINE BAY, AND EVERYTHING WAS STILL...

THE AC COMPRESSOR LOCKED UP AND CAUSED A LIST OF DAMAGE INCLUDING NEEDING A NEW MOTOR. STARTED SMOKING OUTSIDE AND INSIDE THE CAR AND THEN MAKING A HORRIBLE NOISE. REPLACED AC PUMP, BELTS, CRANK PULLEY, BELT TENSIONER, IDLER PULLEY AND BECAUSE THE TIMING BELT ALSO BROKE THIS CAUSED THE DAMAGE TO THE ENGINE. AFTER DOING RESEARCH, THIS SEEMS TO BE THE TREND FOR A 2007 MAZDA CX7. *TR

I WAS DRIVING DOWN THE ROAD WHEN ALL OF A SUDDEN I COULD SMELL SMOKE AND MY AC JUST STOPPED. I TOOK MY 2007 MAZDA CX-7 INTO 3 SHOPS. ONE WAS THE MAZDA DEALER WHERE I BOUGHT THE CAR. ALL 3 PLACES TOLD ME THAT MY AC COMPRESSOR CLUTCH HAD GONE OUT. THE PART AND LABOR IS COSTING ME $750 TO FIX. I HAVE BEEN READING ON SEVERAL ONLINE FORUMS THAT THIS IS A COMMON PROBLEM AND OFTEN LEADS TO THE S-BELT BREAKING AND THE ENTIRE CAR JUST STOPPING WHILE DRIVING. I EVEN HAD ONE OF THE MECHANICS TELL ME THAT IT COULD HAPPEN TO ME AT ANY TIME. *TR
