2007 MAZDA CX-7 Engine Problems

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 SHAFT AND OIL CONTROL CALVE. AT WORST, ALL TIMING CHAIN REPLACEMENTS SHOULD REQUIRE A FUEL PUMP CHANGE IN ORDER TO PREVENT THE SEQUENCE OF EVENTS THAT HAPPENED TO MY CAR AND THOUSANDS OF OTHERS. *JS

MAZDA EXTENDED THE WARRANTY ON AC COMPRESSORS, WELL, MY ORIGINAL COMPRESSOR FAILED AND WAS REPLACED UNDER THAT ORIGINAL WARRANTY. EXACTLY 30,000 MILES LATER THE REPLACEMENT COMPRESSOR FAILED ALMOST 3 YEARS TO THE DATE OF THE ORIGINAL FAILURE. MAZDA IS REFUSING ANY RESPONSIBILITY FOR THIS SINCE NOW MY CAR IS OUT OF WARRANTY. EVENTHOUGH THE REPLACED PART ITSELF IS ONLY 30,000 OLD. THIS VEHICLE IS ALSO EXPERIENCING TIMING BELT ISSUES AND EXTREMELY LOUD ENGINE NOISE. THIS PARTICULAR MODEL YEAR JUST SEEMS TO BE A LEMON ALL AROUND. EVEN THE REPLACEMENT PARTS ARE FAILING. AND THE COMPANY IS NOT HOLDING THEMSELVES RESPONSIBLE AT ALL. I'VE RESEARCH THIS PARTICULAR YEAR AND FOUND MORE THAN ADEQUATE EVIDENCE THAT THESE VEHICLES ARE LEMONS. THE SAME ISSUES ARE BEING REPORTED ACROSS THE WORLD! AND MAZDA IS DOING NOTHING. THE HAZARDS THEY ARE CAUSING ARE TREMENDOUS! SOME FAILURES HAVE RESULTED IN FIRES, QUICK LOSS OF ENGINE POWER...

I WAS STOPPED AT A TRAFFIC LIGHT WITH MY 10 YR OLD IN THE CAR, AND AS SOON AS I PULLED OUT FORM THE TRAFFIC LIGHT WE NOTICED SMOKE AND PEOPLE HONKING THEIR CAR HORNS AT US. I LOOKED IN THE REAR VIEW MIRROR AND THERE WAS A "PUDDLE" OF FIRE ON THE ROAD THAT WAS NOT THERE WHEN I PULLED UP TO THE STOP LIGHT SO I ASSUME IT LEAKED DOWN FROM MY ENGINE. AFTER NOTICING THE FIRE I QUICKLY PULLED OVER (NOT EVEN THROUGH THE INTERSECTION YET) AND INSTRUCTED MY SON TO GET OUT OF THE CAR. I SHUT OFF THE IGNITION OF THE VEHICLE, AND EXITED AS WELL TO CALL 911. BY THE TIME THE FIRE DEPARTMENT ARRIVED, THE CAR WAS TOO FAR GONE TO BE SALVAGED. THE CAR WAS COMPLETELY BURNED, ALL AIRBAGS DISCHARGED FROM THE HEAT OF THE FIRE, AND THE FRONT TWO WHEELS WHERE...

MY GAS LIGHT WAS ON. I WAS GOING TO GET GAS. THE CAR WAS DRIVING FINE THEN I FELT A PULL LIKE A CHUG I DID NOT WANT TO RUN OUT OF GAS. I TURNED AROUND TO GO HOME A FEW BLOCKS AWAY I WOULD RATHER CALL THE AUTOMOBILE CLUB TO BRING GAS TO ME THAN GET STUCK ON EMPTY. THE CAR STARTED PULLING AND CHUGGING AS I STARTED TO GO UP A HILL.I PULLED TO THE RIGHT SIDE OF THE ROAD ROLLED TO A STOP. AAA TOWED ME HOME. I HAD A MASTER MECHANIC COME OUT TO LOOK AT IT. HE TOLD ME MY ENGINE WAS FROZEN RINGS WERE DONE AND I NEEDED A NEW CAR AND IT WASN'T WORTH 5,000.00 TO FIX. SO NOW I HAVE A BEAUTIFUL CAR NOT WORTH ANYTHING. OH YEAH! I'M VERY UPSET! *TR

JUST BOUGHT A USED 2007 MAZDA CX7 ABOUT 2 MONTHS AGO AND THE CAR STARTING PRODUCING SMOKE OUT OF THE TAILPIPE. TOOK THE CAR IN AS IT IS STILL UNDER WARRANTY, AND THE DEALER CLAIMS THAT THE TURBO CHARGER IS GOING OUT IN THE CAR! I ASKED THE DEALER IF THIS IS COVERED UNDER THE WARRANTY AND THEIR RESPONSE WAS THAT IT WAS NOT. THAT IS ABSURD! I WISH I WOULD HAVE READ ALL OF THE COMPLAINTS ABOUT THIS CAR WITH PEOPLE HAVING TO GO THROUGH THE ORDEAL WITH CRAPPY SERVICE FROM THE DEALER BEFORE BUYING IT! THIS OUGHT TO BE INCLUDED IN A RECALL CONSIDERING THE AMOUNT OF TIMES THIS HAS HAPPENED TO BUYERS OF THE CX7. I FEEL TERRIBLE AS THIS WAS PURCHASED FOR MY MOM TO DRIVE WHO IS ON A FIXED INCOME AND CANNOT AFFORD TO HAVE MAJOR REPAIRS DONE ON A CAR THAT WAS PURCHASED...

DRIVING TO WORK ON INTERSTATE TRUCK LOST POWER AND HAD TO ROLL TO SIDE OF THE ROAD UNTIL IT FINALLY STOPPED ROLLING. HAD TRUCK TOWED TO LOCAL MAZDA DEALER, SERVICE MANAGER STATED THE TIMING CHAIN BROKE AND WOULD NEED TO BE REPLACED. ADVISED MANAGER TO FIX THE TIMING CHAIN AT A COST 1700.00, NOTIFIED TWO DAYS LATER TIMING CHAIN WAS FIXED HOWEVER WHEN THE TIMING CHAIN BROKE A PIECE WENT INTO THE ENGINE AND "BROKE' IT. I WAS ADVISED COULD HAVE REPAIRED FOR 8,000.00. COULD NOT AFFORD IT, HAD TRUCK TOWED HOME AND IT HAS REMAINED PARKED FOR 4 YEARS, AND YES I STILL OWED ON IT. HAVE RESEARCHED ONLINE AND SEE THE THOUSANDS AND THOUSANDS OF COMPLAINTS ABOUT THE TRUCK SAME YEAR MAKE AND MODEL AND SAME ISSUE. PLEASE LOOK INTO THIS MATTER. PLEASE PLEASE PLEASE..MAZDA CX7 ARE UNSAFE, I COULD HAVE BEEN KILLED IF THE TRUCK CUT OFF...

DRIVING ON MY WAY TO TENNESSEE, THE CAR HAD A MAJOR POWER LOSS AND SCREECHING NOISE FROM INSIDE THE ENGINE BAY. THE CAR WAS TAKEN TO THE CLOSEST MAZDA DEALERSHIP AND WAS TOLD THAT THE TURBO HAD TO BE REPLACED DUE TO ENGINE SLUDGE. THE CAR HAD REGULAR OIL CHANGES USING THE PROPER AMOUNT AND OIL WEIGHT. MAZDA HAD A RECALL INVOLVING THE TURBO AND THEY DID NOT HONOR IT BECAUSE I WAS ABOUT 1000 MILES OVER THE EXTENDED WARRANTY. *TR

CAR STARTED TO MAKE A TICKING NOISE FROM THE RIGHT SIDE OF THE ENGINE COMPARTMENT. TOOK IT TO A MECHANIC AND WAS DIAGNOSED AS A TIMING CHAIN RELATED ISSUE. WILL COST ABOUT $1500 IN PARTS AND LABOR TO REPLACE TIMING CHAIN, VVT VALVE, AND SPROCKETS. *TR

TL* THE CONTACT OWNS A 2007 MAZDA CX-7. THE CONTACT STATED THAT THE VEHICLE WOULD CONTINUOUSLY EXHIBIT A TICKING NOISE FROM THE ENGINE COMPARTMENT. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO STATED THAT THE NOISE WAS NORMAL BUT THEY WERE UNABLE TO DETERMINE WHAT WAS CAUSING THE NOISE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 49,000 AND THE CURRENT MILEAGE WAS 49,500.

TL* THE CONTACT OWNS A 2007 MAZDA CX-7. THE CONTACT STATED THAT WHILE DRIVING 65 MPH, THE VEHICLE STALLED AS ALL OF THE WARNING LAMPS ILLUMINATED. THE VEHICLE WAS TOWED TO THE DEALER WHERE THE TECHNICIAN DIAGNOSED THAT THE TIMING CHAIN WAS FRACTURED AND CAUSING IRREVERSIBLE DAMAGE TO THE ENGINE. AS A RESULT, THE ENGINE AND THE TIMING CHAIN WOULD NEED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 100,000.

I PURCHASED A BRAND NEW 2007 MAZDA CX-7 IN APRIL 2007, THE VEHICLE STARTED EXPERIENCING ENGINE PROBLEMS IN SEPTEMBER 2007, I WAS TOLD IT MAY HAVE SOMETHING TO DO WITH THE VVT (VARIABLE VALVE TIMING) AND TIMING CHAIN. THE VVT WAS REPLACED BY THE DEALERSHIP A SHORT TIME LATER; HOWEVER, NOT THE TIMING CHAIN. AFTER THE VVT WAS REPLACED MY VEHICLE STARTING TO EXPERIENCE THICK WHITE SMOKE COMING OUT OF THE TAIL PIPES. MY DEALERSHIP TECHNICIAN ADVISED THIS WAS DUE TO A TURBO ISSUE WITH THE ENGINE. ALL OF THIS OCCURRED WITHIN THE FIRST COUPLE YEARS OF MY OWNERSHIP. I HAVE HAD THE TURBO REPAIRED (OUT OF POCKET EXPENSE), AS WELL AS THE VVT (2 TIMES) AND THE TIMING CHAIN IT ALL SEEMS TO NO AVAIL. THE CAR IS REVVING VERY HIGH ON COLD START UPS AND IS NOW EXPERIENCING A CODE AS OF THE LAST COUPLE OF DAYS THAT...

TL- THE CONTACT OWNS A 2007 MAZDA CX-7. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE STARTED TO MAKE A WHINNYING NOISE BEFORE THE CHECK ENGINE LAMP ILLUMINATED. THE CONTACT MENTIONED THAT WHITE SMOKE STARTED TO EMITTED FROM THE EXHAUST. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN DIAGNOSED THAT THE TURBO CHARGER WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 62,839. PM

I DID ALL MY MAZDA CX7 MAINTENANCE SCHEDULE, I PAID A LOT FOR IT. THEN MY CAR STARTED MAKING NOISES, I TOOK IT TO THE DEALER SO MANY TIMES AND THEY SAID THAT THE NOSE WAS NORMAL BECAUSE ITS A TURBO CAR. ONE DAY, RUNNING AT APROX 40 M/H MY CAR LOWER THE SPEED AT NO MORE THAT 20 M/H, IT WAS SUNDAY AFTERNOON SO I TOOK IT TO AN INDEPENDENT MECHANIC (MY CAR WAS OUT OF WARRANTY) AROUND 68 K MILES. THE PROBLEM WAS THE TIMING CH. AFTER WAS SOME FIXED, I TOOK IT TO THE DEALER AND THEY STAYED WITH THE CAR 21 DAYS ( I PAID FOR THE RENT A CAR) THEY TOLD ME THAT WAS ABOUT SOMETHING DIFFERENT AND THEY NEEDED TO WAIT FOR THE PART, SO THEY CHANGED IT BUT IT WASN'T THAT PART, SO THEY PUT EVERYTHING BACK AND SAID THAT WAS THE ENGINE....

DECEMBER 2012 (AT ABOUT 64,000 MILES) DEALER REPLACED TIMING CHAIN UNDER EXTENDED WARRANTY BUT DIDN'T DO ANYTHING TO CORRECT INTERMITTENT POWER LOSS AND ENGINE HESITATION THAT I HAD COMPLAINED TO THEM AT THE TIME. NOVEMBER 2013 (AT ABOUT 78,000 MILES), THE CAR EXPERIENCED SEVERE LOSS OF POWER, STALLING AND HEAVY WHITE SMOKE FROM THE TAILPIPE. DEALER CLAIMED "OIL SLUDGE" CAUSED ENGINE AND TURBO FAILURE AND REFUSED TO BEAR ANY RESPONSIBILITY OR COST TO FIX. MAZDA USA ALSO REFUSED, CLAIMING THE PROBLEMS WERE DUE TO INSUFFICIENT OIL CHANGE BY THE CUSTOMER. SINCE WE CHANGE OIL REGULARLY, WE DON'T BUY MAZDA'S CLAIMS, ESPECIALLY WHEN THEY JUST OPENED UP THE ENGINE LESS THAN A YEAR AGO TO CHANGE THE TIMING CHAIN, AND AT THAT TIME DIDN'T CLAIM THERE WAS ANY "SLUDGE" INSIDE. SEEING MANY SIMILAR CUSTOMER COMPLAINTS ON THE INTERNET, IT SEEMS MAZDA HAS BEEN TRYING TO HIDE A SERIOIUS DESIGN AND/OR MANUFACTURING...

IN SEPTEMBER 2013 MY CAR SUDDENLY STOPPED ACCELERATING WHILE DRIVING IT... HEARD A LOUD, GRINDING, SCREECHING NOTICE.. AND SUDDENLY MY "CHECK ENGINE" LIGHT CAME ON. BROUGHT MY CAR TO MAZDA.. 4 DAYS LATER THEY TELL ME THAT MY TURBOCHARGER BLEW.. AND THAT I HAVE DAMAGE TO MY ENGINE. TOLD THEM I PURCHASED AN EXTENDED WARRANTY IN 2010 WHEN I BOUGHT THE CAR.. WARRANTY CO WAS NOTIFIED... THEY SENT THEIR OWN INSPECTOR TO LOOK AT MY CAR.. A WEEK LATER THEY TELL ME THAT THEY WILL NOT COVER THE DAMAGE DUE TO EXCESSIVE SLUDGE IN MY ENGINE. AND.... THAT I MUST PRODUCE EVERY OIL CHANGE RECEIPT FROM 2010-2013 TO SHOW PROOF OF MAINTENANCE. I GAVE THEM ALL THE RECEIPTS I COULD GET... AND DECIDED TO DO A LITTLE RESEARCH MYSELF ON THE ISSUE. ALL I HAVE TO SAY IS.. WOW. APPARENTLY, THERE IS A MAJOR DEFAULT IN HOW THE TURBOCHARGER IN...

TIMING CHAIN REPLACED ON 2007 MAZDA CX7, JULY 2013. VEHICLE OVER EXTENDED WARRANTY ISSUED BY MAZDA, REPAIR WAS OUT OF POCKET, EVEN THOUGH THIS IS VERY COMMON PROBLEM WITH THIS YEAR MAZDA. NOW 5 MONTHS LATER, SECOND TIMING CHAIN HAS GONE BAD AND MAZDA IS REFUSING TO ACCEPT RESPONSIBILITY STATING THAT THE NEW TIMING CHAIN FAILURE WAS DUE TO LOW OIL IN VEHICLE. I HAVE SERVICE RECEIPTS TO PROVE THAT ALL OIL CHANGES HAD BEEN DONE, AND THAT THIS WAS NOT THE CAUSE OF THE SECOND TIMING CHAIN FAILING, BUT MORE OF CONTINUANCE OF FAULTY, DEFECTIVE MAZDA PARTS. THIS IS A HUGE PROBLEM WITH THIS COMPANY WITH AN OUTSTANDING NUMBER OF CONSUMER COMPLAINTS. THEY DO NOT WANT TO ACCEPT ANY RESPONSIBILITY FOR THEIR OWN PROBLEM, INSTEAD PUTTING IT ALL BACK ON THE CONSUMER. PLEASE, GET INVOLVED AND PUT A STOP TO THIS BEFORE THESE DEFECTIVE PARTS CAUSE SOMEONE TO LOSE...

DRIVING ON THE HIGHWAY, TURNED ON THE A/C AND A BURNING SMELL STARTED EMITTING INTO THE CAR. OPEN UP THE WINDOWS AND THE ODOR WAS COMING FROM THE ENGINE. VERY AFRAID TO DRIVE CAR AND AFTER READING NUMEROUS REPORTS OF SIMILAR INCIDENTS HERE: HTTP://WWW.ARFC.ORG/COMPLAINTS/2007/MAZDA/CX-7/ENGINE/PROBLEM.ASPX I'M AFRAID MY CAR IS SUFFERING FROM THE SAME DEAL. *TR

I PURCHASED A USED 2007 MAZDA CX 7 AUGUST 2012 WITH 60K MILES. RECENTLY TOOK CAR FOR OIL CHANGE AT THE DEALERSHIP RECOMMEND TO NEEDING TIMING CHAIN REPLACEMENT, REPLACEMENT OF ENGINE COOLANT AND OIL LEAKING AROUND THE ENGINE. THE ENGINE IS MAKES A LOUD TAPPING SOUND LIKE THE ENGINE ROD IS GOING OUT. *TR

A FRIEND OF OURS WAS DRIVING TO PICK US UP FROM THE AIRPORT (OUR CAR HADN'T BEEN STARTED FOR A COUPLE OF WEEKS) AND, ABOUT 15 MILES INTO THE TRIP, THE AC QUIT WORKING. WHEN HE GOT TO THE AIRPORT, THE CAR ENGINE WAS SMOKING, THERE WAS A BURNING SMELL COMING FROM THE ENGINE, AND IT SOUNDED LIKE A BEARING WAS OUT OF WHACK. WE DROVE IT HOME (APPROXIMATELY 45 MILES), AND THE NOISE GOT LOUDER AND THE ENGINE STARTED RATTLING LOUDER AND LOUDER THE CLOSER WE GOT TO HOME. WE TOOK IT TO A MAZDA DEALERSHIP THIS MORNING, AND THEY INFORMED US THAT THE AC COMPRESSOR HAD SEIZED AND IT, ALONG WITH THE BELT (IN ADDITION TO ANY OTHER PARTS THAT MAY HAVE BEEN DAMAGED) NEEDED TO BE COMPLETELY REPLACED AND THE REFRIGERANT FLUSHED/REFILLED. I DID RESEARCH AND FOUND OUT THAT THIS IS A VERY COMMON, KNOWN ISSUE IN...

TURNING INTO A WALMART PARKING LOT MY CAR SHUT DOWN FOR NO REASON. ALMOST GOT HIT BY ANOTHER CAR THAT WAS PASSING BY SINCE I WAS NOT ABLE TO TURN. TURNING INTO MY APARTMENT COMPLEX THE CAR TURNED OFF AGAIN. STARTED TO RESEARCH ISSUES WITH THIS CAR AND I RAN INTO MANY SIMILAR COMPLAINTS. CAR TURNED OFF ANOTHER 4 TIMES. CAR SHAKES WHEN I TURN AC ON.AND WHEN I PLACE IT ON REVERSE. ALSO HAD THE CLICKING NOISE BUT IT SEEMED TO GO AWAY. THERE SEEMS TO BE SOME SENSOR ISSUES. I TOOK MY CX7 TO MAZDA SO THAT THEY CAN SEE WHAT IS GOING ON. THEY RAN TESTS. CAME BACK AND SAID IT WOULD COST ME ABOUT $3500. IT WAS A LIST OF THINGS THAT COULD BE WRONG THEY SAID, THEY WERE NOT SO SURE WHAT TO SAY. MECHANIC THEN STATED THAT SINCE HE WORKS AT MAZDA HE PROBABLY...

WHILE DRIVING DOWN ROAD TIMING CHAIN JUMPED CAUSING SEVERE INTERNAL ENGINE DAMAGE ... (BENT ALL VALVES) APPROXIMATELY $8000. TO REPAIR! *TR

AS I WAS DRIVING, THE TIMING CHAIN BROKE AND IMPLODED INTO THE ENGINE, DAMAGING THE ENGINE WHICH NOW NEEDS REPLACEMENT. THIS APPEARS TO BE A COMMON OCCURRENCE WITH THIS VEHICLE. *TR

WHILE DRIVING ON THE HIGHWAY I HEARD A TICKING NOISE AFTER A FEW SECONDS LATER THE CAR LOST POWER AND SMOKE CAME OUT OF THE EXHAUST. WHEN I PULLED OVER I TOOK THE COVER OFF FROM THE ENGINE AND NOTICED THAT THERE WAS OIL COMING OUT FROM WHERE THE TOP OF THE OIL GOES.THE OIL PRESSURE ON THE BLOCK WAS COMPROMISED DUE TO FAILURE OF THE TURBO. WHEN TAKEN TO THE ROGER BEASLEY MAZDA DEALERSHIP AND THE CAR WAS CRANKED THE DIP STICK SHOT OUT FROM THE ENGINE. THE DEALERSHIP INDICATED THAT THERE WAS CARBON BUILD UP BUT COULD NOT EXPLAIN WHY. THE CAR WAS TOWED TO ANOTHER ACS CERTIFIED MECHANIC AND CONFIRMED THAT THE ENGINE FAILURE WAS DUE TO THE FAILURE OF THE TURBO. BEFORE TAKING THE TRIP ON 4-18-2013 I TOOK MY CAR THE MAZDA OF MESQUITE DEALERSHIP BECAUSE I HEARD A TICKING NOISE AND THE TECHNICIAN INDICATED...

MY CHECK ENGINE LIGHT CAME ON AS I WAS DRIVING AT 40 MILES PER HOUR. I DID NOT NOTICE A DIFFERENCE IN THE WAY THE CAR WAS HANDLING, HOWEVER I TOOK MY CAR INTO MY LOCAL MAZDA DEALER TO HAVE IT CHECKED. THEY INFORMED ME THE CARS TIMING BELT NEEDED TO BE REPLACED AND THERE WAS SLUDGE ON THE ENGINE. IRONICALLY I HAD JUST HAD MY OIL CHANGED AND MY ENGINE CLEANED OF SLUDGE LESS THAN 2 WEEKS PRIOR. WE SUBMITTED THE CLAIM THROUGH MY EXTENDED WARRANTY AND AFTER A WEEK GOT IT APPROVED. THE MORNING I WAS SLATED TO PICK UP THE CAR I WAS TOLD BY THE DEALER THAT THERE WAS STILL AN ISSUE THAT THEY NEEDED THE CAR LATER. A FEW DAYS LATER THEY TOLD ME I NEEDED MY ENGINE REPLACED. THE EXTENDED WARRANTY DENIED THE ORIGINAL CLAIM NOW AND THE CLAIM FOR A NEW ENGINE DUE...

A/C COMPRESSOR LOCKED UP. *TR

TL* THE CONTACT OWNS A 2007 MAZDA CX7. THE CONTACT STATED THAT WHILE DRIVING 60 MPH, THE VEHICLE STALLED WITHOUT WARNING WHILE ALL OF THE INSTRUMENT PANEL LIGHTS ILLUMINATED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC FOR DIAGNOSIS WHERE IT WAS ADVISED TO THE CONTACT THAT THE ENGINE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 82,000. *TR

2007 MAZDA CX-7: TIMING CHAIN AND VVT HUB STARTED TO FAIL PREMATURELY, LEADING THE CAR TO NOT BE DRIVEN AND POSSIBLE ENGINE FAILURE AT SPEED. MAZDA IS AWARE OF THIS DESIGN FLAW AND POSSIBLE HAZARDOUS SITUATION, BUT IS RELUCTANT TO REPAIR AT THEIR COST. ENGINE MOUNT #3 HAS ALSO BROKEN CREATING UNSAFE SITUATION. *TR

65MPH CAR DROPPED OUT OF 6TH AND POWERED DOWN. TURBO KILLED THE ENGINE. *TR

I WAS ACCELERATING TO MERGE INTO EXPRESSWAY TRAFFIC WHEN I HEARD A LOUD WHINE/SQUEAL FROM UNDER THE HOOD AND THE CAR LOST A SIGNIFICANT AMOUNT OF POWER. THE NOISE WAS SO UNEXPECTED AND UNRECOGNIZABLE THAT THE SHOCK I EXPERIENCED WHEN I HEARD IT CAUSED ME TO TENSE UP AND VEER OFF TO THE RIGHT. FORTUNATELY AS I WAS ON A RAMP THERE WERE NO VEHICLES TO THE RIGHT OF ME TO HIT. I WAS ABLE TO GET UP TO HIGHWAY SPEED BY GRADUALLY ACCELERATING ON THE SHOULDER BEFORE MERGING AND THEN EXITED AT THE NEXT EXIT. THE VEHICLE IS NOW AT A MAZDA DEALERSHIP AND I'VE BEEN TOLD IT WAS A TURBO CHARGER FAILURE. MY RESEARCH INTO THIS ISSUE ON THIS MAKE, MODEL AND YEAR, HAS PROVEN THAT THIS IS A KNOWN ISSUE FOR MAZDA AND THEY HAVE EXTENDED THEIR STANDARD WARRANTY COVERAGE TO OWNERS FOR ADDITIONAL MONTHS AND/OR MILES....

TL* THE CONTACT OWNS A 2007 MAZDA CX-7. THE CONTACT STATED THAT THE VARIABLE VALVE TIMING (VVT) BURNED OUT AND CAUSED SMOKE TO EMIT FROM THE EXHAUST PIPES. THE CONTACT TOOK THE VEHICLE TO A DEALER FOR A DIAGNOSTIC TEST. THE DEALER STATED THAT THE VVT VALVE TIMING CHAIN WAS DEFECTIVE AND REPLACED THE VVT VALVE TIMING CHAIN. THE CONTACT STATED THAT THE VVT VALVE TIMING CHAIN WAS REPLACED FOUR TIMES PRIOR TO THE RECENT FAILURE. THE FAILURE MILEAGE WAS 70,000.

TL* THE CONTACT OWNS A 2007 MAZDA CX-7. THE CONTACT STATED THAT WHILE DRIVING 65 MPH, THE VEHICLE OVERHEATED AND THE TURBO SYSTEM MALFUNCTIONED, CAUSING THE ENGINE TO SLUDGE AND THE VEHICLE TO STALL. THE VEHICLE WAS TAKEN TO THE DEALER, WHO CONFIRMED THAT THERE WAS SLUDGE IN THE ENGINE AND ADVISED THAT THE ENGINE WOULD NEED REPLACING. THE ENGINE WAS NOT REPLACED. THE FAILURE MILEAGE WAS 93,000.

I WAS EXPERIENCING A SHAKE IN THE STEERING WHEEL AT HIGH SPEEDS, WHICH WE ATTRIBUTED TO A TIRE/WHEEL/ALIGNMENT ISSUE. I MADE AN APPOINTMENT WHEN THE CHECK ENGINE LIGHT CAME ON. THE DEALERSHIP TOLD ME I NEEDED THE TIMING CHAIN (AND ASSORTED PERIPHERALS) REPLACED...FOR THE SECOND TIME IN TWO YEARS. THE FIRST TIME WAS COVERED BY WARRANTY, BUT ONLY AFTER I PRODUCED THE RECORDS TO SHOW THE OIL HAD BEEN CHANGED REGULARLY. THE SECOND TIME WAS NOT COVERED UNDER WARRANTY. IT COST $1500 TO REPLACE THE ENTIRE ASSEMBLY THAT WAS LESS THAN TWO YEARS OLD. THE DEALERSHIP HAS RECOMMENDED IGNORING THE MANUAL ON OIL CHANGES (EVERY 7500 MILES) AND CHANGING IT EVERY 3000 TO HOPEFULLY CATCH ANY FURTHER ISSUES. THEY SAID BECAUSE THE TURBO RUNS VERY HOT, IT BURNS UP THE OIL QUICKLY. MY CAR WAS VERY LOW WHEN I TOOK IT IN. THEY ALSO SAID THE CHECK ENGINE LIGHT WILL...

WE WERE DRIVING HOME ON CHRISTMAS EVE GOING ABOUT 65 MPH WHEN THE CARS ENGINE JUST DIED. WE LOST ALL POWER TO THE CAR INCLUDING THE POWER STEERING. THANKFULLY WE WERE ON A STRAIGHT STRETCH AND DUE TO TIME OF NIGHT THERE WERE NOT MANY OTHER CARS ON THE ROAD. WE WERE ABLE TO COAST TO THE SIDE OF THE ROAD SAFELY. THE CAR WAS TOWED TO A DEALERSHIP WHERE IT WAS DISCOVERED THE TIMING CHAIN BROKE AND DAMAGED THE ENGINE IN THE PROCESS. AFTER RESEARCHING THIS ONLINE I DISCOVERED HUNDREDS IF NOT THOUSANDS OF COMPLAINTS ABOUT A BROKEN TIMING CHAIN THAT REQUIRED REPLACEMENT OF THE ENGINE. SOME OF THESE COMPLAINTS WERE AS EARLY AS 30,000 MILES. THERE WAS EVEN DISCUSSION ABOUT A RECALL ON THE TIMING CHAIN FROM MAZDA SAYING THAT IT WAS DEFECTIVE BUT MAZDA WAS NOT ALWAYS HONORING THIS RECALL. OBVIOUSLY BASED ON THESE COMPLAINTS THERE IS...

I BOUGHT MY 2007 MAZDACX7 IN FEB 2012.IVE ONLY HAD THE CAR FOR 8 MTHS WHEN THE TURBO WENT OUT ALSO THE PISTON RINGS,FIRST THE DRIVER SIDE WINDOW CAME OFF THE TRACK COULD'NT LET WINDOW DOWN ANYMORE,THE THE DRIVERSIDE DOOR HANDLE BROKE,CALLED MAZDA THEY SAID THE HANDLE WOULD COST 200.00 TO REPLACE,COULD'NT AFFORD TO FIX IT STILL BROKEN,THEN IN 10/20121 THE TURBO WENT OUT,CALLED THE DEALER WHERE I BOUGHT THE CAR FROM AND HE TOLD ME TO TAKE THE CAR TO MAZDA DEALERSHIP,SO I DID MAZDA MECHANIC TOLD ME THAT IT WOULD COST OVER 2500.00 TO FIX THE TURBO NO COUNTING WHAT ELSE IS WRONG WITH THE CAR BECAUSE THE CAR STARTED SMOKING SOO BAD BEFORE I LEFT THE MAZDA DEALERSHIP THE MECHANIC AT MAZDA SAID IT DOESN'T MAKE SENSE TO FIX MY TRUCK BECAUSE WHO I BOUGT THE CAR FROM THEY SOLD ME A LEMON THAT I MIGHT AS...

TL* THE CONTACT OWNS A 2007 MAZDA CX7. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 20 MPH, THE VEHICLE SUDDENLY STALLED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHERE IT WAS FOUND THAT THE VVT TIMING CHAIN HAD FAILED AND NEEDED TO BE REPLACED. THE CONTACT WAS ALSO INFORMED THAT THE TURBO HAD FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 56,800.

CHECK ENGINE LIGHT DUE TO THE EGR VALVE = EXHAUST GAS RECIRCULATION VALVE BEING STUCK IN THE OPEN POSITION WITH 51K MILES. THE DEALERSHIP REPLACED THE VALVE (PART NUMBER L3K9-20-300A) AND THE GASKET (PART NUMBER LF6T-20-305) FOR $882.63 BEING THAT IT WAS NOT COVERED UNDER MY CERTIFIED PRE OWNED WARRANTY OR MY EXTENDED WARRANTY SINCE IT IS PART OF THE EMISSIONS PACKAGE I PAID, IN FULL, OUT OF POCKET. I HAVE CHECKED SEVERAL ONLINE FORUMS AND HAVE SEEN THIS IS A COMMON OCCURRENCE FOR 2007 CX7 BETWEEN 25K AND 55K MILES. I THINK THIS IS A MUCH LARGER PROBLEM THAN REGULAR WEAR AND TEAR REQUIRING AN INVESTIGATION. *TR

DRIVING EAST ACROSS THE BAY BRIDGE FROM SF, THE ENGINE MADE A WHEEZING NOISE. AFTER A MILE THE POWER DROPPED, AND THE CAR WOULD ONLY TRAVEL AT 30 MPH. NO ENGINE LIGHT CAME ON TO WARN OF THIS, EVEN DURING THE EVENT. AT THIS POINT IT WAS OBVIOUS THAT IT NEEDED REPAIR ATTENTION, AND WE FOUND A MAZDA DEALER/REPAIR SHOP RELATIVELY CLOSE BY TO DRIVE IT TO. ONCE THEY HAD A CHANCE TO DIAGNOSE THE PROBLEM, THEY REPORTED TO US THAT ENGINE 'SLUDGE' WAS TO BLAME. THE TIMING CHAIN HAD BEEN RUBBING, AND THE VVT ACTUATOR HAD BEEN COMPROMISED. TURBO GALLEYS WERE ALSO PLUGGED. IN JAN. OF THIS YEAR, MAZDA POSTED AN EXTENDED WARRANTY FOR CX-7'S TIMING CHAIN AND VVT. HOWEVER, THE DEALER INFORMED US AFTER CHECKING WITH MAZDA THAT WE WERE NOT ELIGIBLE FOR THE WARRANTY. GAPS IN OUR HISTORY OF REPAIR WAS THE GIVEN REASON. AFTER AN APPEAL,...

WHILE DRIVING THE CAR THE AC COMPRESSOR MADE A NOISE AND CEASED TO WORK. I NOTICED A STRANGE SMELL COMING FROM THE CAR FOLLOWED BY SMOKE COMING FROM THE ENGINE COMPARTMENT. I PULLED OVER AND OPENED UP THE HOOD TO FIND SMOKE POURING OFF OF THE AC COMPRESSOR AND A LARGE AMOUNT OF SPARKS SHOOTING OFF OF IT. THIS INDECENT OCCURRED 4 MONTHS AFTER THE EXTENDED WARRANTY ON THE AC COMPRESSOR RAN OUT. I'M NOT SURE WHY THIS ISN'T AN ISSUE THAT IS SUBJECT TO A RECALL, AS THERE WAS A VERY REAL DANGER OF A FIRE BREAKING OUT. *TR

VEHICLE WAS TRAVELING NORTH BOUND WHEN CHECK ENGINE LIGHT CAME ON AS WELL AS AT ON THE DRIVER CONSOLE, THE CAR WOULD NOT ACCELERATE OR SHIFT FROM 3RD GEAR IN THE MIDDLE HIGHWAY CAUSING THE VEHICLE TO DECREASE IN SPEED. *TR

ON 7/11/12 MY WIFE WAS DRIVING ON THE ENTRANCE RAMP TO THE FL. TURNPIKE WHEN HER MAZDA CX7, 07 ENGINE TURNED OFF COMPLETELY WITHOUT WARNING. SHE WAS ON A ONE LANE ROAD WITH A BLIND SIDED CURVE WHEN THIS HAPPENED. A 18 WHEELER TRUCK WAS COMING UP BEHIND HER AND ALMOST REAR ENDED HER VEHICLE. FORTUNATELY THE DRIVER OF THE TRUCK WAS ABLE TO STOP BEFORE HITTING MY WIFE CAR. AFTER A INVESTIGATION OF THE ENGINE PROBLEM I FOUND OUT THAT IT WAS A BAD TIMING CHAIN THAT CAUSED THE VEHICLE TO SHUT OFF THE WAY IT DID. I CALLED THE MAZDA MANUFACTURE AND THEY TOLD ME THAT THEY WERE AWARE OF THE TIMING CHAIN PROBLEM AND THAT'S WHY THEY SENT OUT LETTERS FOR AN EXTENDED WARRANTY ON THE TIMING CHAIN PROBLEM. THE ALSO STATED THAT THE ONLY WAY THEY WOULD REPLACE THE PART IS IF I COULD SHOW RECORDS...

THE VEHICLE SUDDENLY STOPPED RUNNING WHILE TRAVELING AT 65 MPH ON INTERSTATE 95. THE VEHICLE WAS SAFELY MOVED TO THE SIDE OF THE ROAD WHERE IT WAS THEN TOWED TO THE DEALER WHERE IT WAS PURCHASED. THE SERVICE REPRESENTATIVE INDICATED THAT THE ENGINE WOULD HAVE TO BE OPENED AT A COST OF $500 TO DETERMINE THE CAUSE OF THE PROBLEM. THEY SUSPECTED THAT THE TIMING CHAIN HAD BROKEN. AFTER CONSULTING WITH MAZDA CUSTOMER SERVICE, I WAS ADVISED TO HAVE THE VEHICLE TOWED TO A MAZDA DEALER. THE VEHICLE WAS TOWED TO THOMPSON MAZDA IN BALTIMORE, MARYLAND WHERE IT WAS CONFIRMED THAT THE TIMING CHAIN HAD BROKEN AND THAT THE ENGINE WOULD HAVE TO BE REPLACED. MAZDA HAD PROVIDE AN EXTENDED WARRANTY ON THE TIMING CHAIN FOR 7 YEARS OR 70,000 MILES. THE WARRANTY INDICATED THAT IF THERE WAS A TIMING CHAIN NOISE TO BRING INTO A MAZDA DEALER TO HAVE...

FELT SLIGHT JOLT, AND IMMEDIATELY LESS POWER, THEN ENGINE JUST STOPPED. MY OPINION IS THAT THE TIMING CHAIN FIRST "JUMPED" A TOOTH, THEN FAILED ALTOGETHER. I WAS ABLE TO COAST SAFELY OFF TO THE SHOULDER, WHERE I CALLED FOR A TOW. CAR WAS FLATBEDDED BACK TO THE DEALER AT MY REQUEST, AS THEY HAVE DONE ALL WORK ON THE CAR SINCE DAY 1. DEALER STATED SEVERAL DAYS LATER THAT ENGINE HAD NO COMPRESSION IN TWO OF THE FOUR CYLINDERS, AND A REMANUFACTURED ENGINE WOULD BE REQUIRED AT A COST OF $6400.00. LATER, HAVING RESEARCHED THIS, IT IS A COMMON PROBLEM AND SERIOUSLY PREMATURE FOR THIS MILEAGE AND FOR A CAR DRIVEN MODERATELY AND ON WHICH ALL RECOMMENDED MAINTENANCE HAS BEEN PERFORMED (BY THIS DEALER). I STATED MAZDA SHOULD STAND BEHIND THIS AND CONTRIBUTE ALL OR PART OF THE REPAIR BILL. SEVERAL DAYS LATER, DEALER STATES MAZDA REFUSED. *TR

MY HUSBAND WAS DRIVING THE VEHICLE DOWN A BACKROAD HIGHWAY GOING 60 WHEN ALL OF A SUDDEN THE CAR STOPPED. THERE WAS NO NOTICE, NO NOISE NOTHING. THE POS WAS TOWED TO THE LOCAL MAZDA DEALERSHIP. THE LOOKED AT THE VEHICLE AND SAID "TIMING CHAIN..$3000". OK, NOT WHAT WE EXPECTED BUT FINE, FIX IT. 24 HOURS LATER, THEY CALLED TO ADVISE THAT THE ENGINE IS BLOWN $7000. I CONTACT THE MAZDA CUSTOMER SERVICE ( AKA PEOPLE WHO ARE TRAINED TO TELL YOU THAT YOU ARE SOL) TO SEE IF THERE WAS ANY RECALL OR ANY OTHER THINGS THAT MAY COVER THIS. NO, NOTHING BUT A EXTENSION WAS MAILED JAN 2012 TO ADVISE THAT THE TIMING CHAIN WAS EXTENDED FOR REPAIR. NO NOTICE WAS RECEIVED AND THE ADDRESS THEY HAD ON FILE WAS CORRECT. SO HERE WE SIT WITH A WORTHLESS POS THAT NOBODY WANTS TO TAKE RESPONSIBILITY FOR. I WOULD...

MY HUSBAND WAS DRIVING HOME WHEN HE SUDDENLY HEARD A LOUD WHINING NOISE THEN LOST POWER. ON THE WAY TO THE DEALER, HE NOTICED IT WAS SMOKING. *TR

WHILE DRIVING ON INTERSTATE HIGHWAY, LOUD TICKING AND WHIRRING SOUND CAME FROM ENGINE. BLACK SMOKE CAME FROM REAR TAILPIPES AND WHITE SMOKE FROM UNDER THE HOOD. VEHICLE LOST POWER AND STOPPED. *TR

MY MAZDA BEGAN MAKING A CLANGING SOUND AT IGNITION. I TOOK THE MAZDA TO SUSSMAN MAZDA IN ABINGTON, PA. I WAS TOLD THAT THOUGHT THE WARRANT 5 YRS/60,000 MILES HAD EXPIRED. HOWEVER, MAZDA HAD EXTENDED THE WARRANTY ON THE VVT ACTUATOR AND TIMING CHAIN DUE TO THIS BEING A KNOW PROBLEM. I WAS ASKED TO PRODUCE ALL MAINTENANCE RECORDS ON THE CAR. I DID NOT HAVE EVERY SINGLE SERVICE RECORD AND WAS DENIED REPAIR BY MAZDA. I CALLED THE MAZDA CORPORATE OFFICE AND SPOKE WITH A REPRESENTATIVE. THE REPRESENTATIVE TOLD ME THAT MY CLAIM WAS DENIED. I ASKED TO SPEAK WITH A SUPERVISOR BUT I WAS DENIED. I CALLED BACK AND WAS TOLD THAT A SUPERVISOR WOULD CALL ME BACK ON 08/30/12. IT IS 10PM AND NO ONE HAS CALLED ME BACK. IT APPEARS THAT MAZDA IS DOING EVERYTHING POSSIBLE NOT TO REPAIR A KNOWN DEFECT ON THE MAZDA CX7....

WHILE DRIVING HOME FROM WORK 8/23/12, MY HUSBAND NOTICED THAT THE A/C WAS NOT COOLING AND THAT THE ENGINE STARTED MAKING A SQUEALING NOISE. HE STATED THAT THE A/C COMPRESSOR WAS FAILING. FORTUNATELY FOR US, HE MADE IT HOME SAFELY. IF IT FAILED COMPLETELY WHILE DRIVING, THE CAR (OR HE) COULD HAVE DIED IN THE MIDDLE OF THE INTERSTATE.WE HAD RECEIVED THE EXTENDED WARRANTY NOTICE FOR THE A/C COMPRESSOR. SO, WE TOOK IT TO OUR LOCAL MAZDA DEALERSHIP/SERVICE DEPARTMENT FOR REPAIR. THE TECHNICIAN STATED THAT WE HAD JUST EXCEEDED OUR WARRANTY COVERAGE. OUR VEHICLE TURNED 5 YEARS OLD ON 6/30/12 AND HAS 60,598 MILES. HE STATED THAT WE WOULD HAVE TO CONTACT THE MAZDA CORPORATE OFFICE TO REQUEST ASSISTANCE. THE CORPORATE REPRESENTATIVE STATED THAT THEY WOULD CONTACT OUR DEALERSHIP AND TAKE THE MATTER UNDER REVIEW. SHE STATED THAT IF THEY DENIED THE CLAIM THERE WAS NO ONE ELSE AT MAZDA...

I DROVE 200 MILES STOPPED THE CAR TO GET SOMETHING TO EAT, WHEN I RESTARTED IT A LOUD WHISTLING NOISE CAME FROM ENGINE AND WOULDN'T STOP. CALLED ROADSIDE ASSISTANCE AND IT WAS TOWED 2 DAYS LATER BECAUSE IT HAPPENED ON A SATURDAY NIGHT. IT TOOK 3DAYS FOR IT TO BE FIXED AND I'M NOT SURE IT IS RUNNING PROPERLY. I ALSO HAD THE TIMING CHAIN REPLACED AT 60,000 MILES. I WILL NEVER BUY ANOTHER MAZDA. *TR

TL* THE CONTACT OWNS A 2007 MAZDA CX7. THE CONTACT STATED THAT WHEN DRIVING OVER 20 MPH, THERE WAS A LOUD NOISE COMING FROM THE ENGINE. THE VEHICLE WAS TAKEN TO THE DEALER WHO STATED THAT THERE WAS A FAULTY TURBO ENGINE CHARGER WHICH NEEDED TO BE REPLACED. THERE WERE NO RECALLS FOR THE VEHICLE. THE VEHICLE WAS NOT REPAIRED.

WHILE DRIVING WITH MY AC (AIR CONDITIONING) ON, IT SUDDENLY STARTED BLOWING WARM AIR. THE CAR FILLED UP WITH A BURNT TIRE LIKE SMELL AND I QUICKLY TURNED THE AIR CONDITIONING OFF. AFTER GIVING IT A FEW MINUTES AND PARKING MY CAR ON A SHOULDER LANE, I TURNED THE AIR CONDITIONING BACK ON TO SEE IF IT'S GOING TO START WORKING AGAIN (WHILE THE CAR WAS STILL RUNNING). MY AC WAS STILL BLOWING WARM AIR BUT NOW THERE WAS A LOUD NOISE WHAT APPEARED TO BE COMING FROM THE ENGINE ALONG WITH THE BURNT TIRE LIKE SMELL. I DECIDED TO RETURN HOME AND HAVE MY HUSBAND TAKE A LOOK AT IT BEFORE I CONTACT THE DEALERSHIP SERVICE TO FIX IT. AS MY HUSBAND OPEN THE HOOD OF THE CX7 AND I TURNED ON THE AC THERE APPEARED TO BE ALOT OF SPARKS COMING FROM THE AC AIR COMPRESSOR, RIGHT BESIDE...
