2007 MAZDA CX-7 Engine And Engine Coolingengine Problems

I WAS DRIVING MY MAZDA CX-7 ON THE HIGHWAY AROUND 65 MPH WHEN MY CAR STARTING MAKING A LOUD NOISE FROM THE ENGINE AND HAD A SUDDEN LOSS IN POWER. SO I PULLED OVER IN THE NEXT TOWN AND STAYED IN A MOTEL FOR THE NIGHT. THE NEXT DAY I RENTED A TRAILER FROM UHAUL TO TOW THE CAR TO A MAZDA DEALER WHO STATED THAT MY ENGINE NEEDED TO BE OPENED TO PROPERLY DIAGNOSE THE ACTUAL PROBLEM. PER THE MAZDA TECHNICIAN THAT INSPECTED MY CAR, THE TIMING CHAIN (VVT) WAS MISSING A PIN AND CAUSED THE ENGINE TO BREAK. THEREFORE MY ENGINE NEEDED TO BE REPLACED. AT THE PRICE IT WAS TO REPLACE THE ENGINE, I OBTAINED A SECOND OPINION FROM A NON-MAZDA MECHANIC WHO STATED THAT MY ENGINE ALSO NEEDED TO BE REPLACED. I REPLACED MY ENGINE AT 72,127 MILES, FOR APPROXIMATELY $6K, WHICH IS SLIGHTLY OVER THE...

TIMING CHAIN WENT TAKING ENGINE AT 42K MILES AND WE WERE FIRST DENIED WARRANTY WORK DUE TO SLUDGE ENGINE WITH MAZDA STATING IT WAS OUR LACK OF MAINTENANCE. AFTER FILING FOR BBB ARBITRATION THE AGREED TO REPLACE ENGINE AND TURBO IF WE PAID THE $900 LABOR BILL. CAR CAME BACK AFTER A MONTH WITH A RATTLE AND PUTTING OUT WHITE SMOKE.

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...

I BOUGHT MY 2007 MAZDA CX-7 ON NOVEMBER 2, 2008 FROM TUSTIN MAZDA. FROM DAY ONE I HAVE EXPERIENCED AN INTERMITTENT METAL KNOCKING NOISE WHILE ACCELERATING. IT SOUNDS LIKE 3 OR 4 CLICKS AND I EXPERIENCE A SLIGHT LOSE OF POWER. I HAVE TAKEN THE VEHICLE BACK TO THE DEALER MORE THAN 4 TIMES. SOMETIMES THEY HAVE IT FOR DAYS; THE LAST TIME FOR TWO WEEKS. THE FIRST FEW TIME THEY SAID THEY COULD NOT REPLICATE THE PROBLEM. ABOUT A MONTH AGO THE DEALER SAID THEY FIXED IT. THEY ALSO SAID MY OIL WAS SLUDGY AND SUGGESTED A OIL FLUSH. I DID NOT OP FOR THE OIL FLUSH BECAUSE MY REGULAR MECHANIC SAID THEY ARE OVER-RATED AND A FEW OIL CHANGES SHOULD CLEAR IT UP AND THE OIL THE DEALER USED MAY BE PRONE TO SLUGGING UP. THE NOISE RETURNED ALMOST THE DAY I GOT THE CAR BACK. I RETURNED...

LUCKILY I WAS ABLE TO GET OVER THE 5 LANES OF TRAFFIC AND PULL THE CAR OFF TO THE SIDE. AFTER I TURNED MY CAR OFF, IT NEVER CRANKED AGAIN AFTER THAT.

I OWN A 2007 MAZDA CX-7 WHILE DRIVING DOWN THE ROAD A 60 MPH THE MOTOR SHUT DOWN AND LOST ALL POWER. THE CAR HAS 52,000 MILES ON IT, AND IS STILL UNDER MANUFACTURES WARRANTY. I TOOK IT TO A LOCAL MAZDA DEALER TO HAVE IT FIXED. AFTER 2 WEEKS OF WAITING THEY INFORMED ME THAT MAZDA CORP WOULD NOT COVER IT UNDER WARRANTY DUE TO ENGINE SLUDGE. THE OIL HAS BEEN CHANGED AT INTERVALS OF 3000 TO 3500 MILES. WHY WILL THEY NOT ADDRESS THIS PROBLEM IF SO MANY OTHER PEOPLE HAVE HAD THE SAME ISSUE WITH THIS YEAR, MAKE, AND MODEL? THIS IS A SERIOUS SAFETY ISSUE AND COULD CAUSE AN ACCIDENT OR FIRE. *TR

THIS HAPPENED SUDDENLY AT HIGHWAY SPEED AND IS CONSIDERED A SERIOUS SAFETY DEFECT. I SEARCHED THE NHTSA SITE AND FOUND MORE THAN 50+ OTHER SUCH COMPLAINTS. WHY THIS MODEL HAS NOT BEEN RECALLED IS A MYSTERY TO ME? *TR

I OWN A 2007 MAZDA CX7 THAT THE A/C COMPRESSOR SEIZED UP ON CAUSING A NEAR FIRE UNDER THE HOOD. I HEARD AN AWFUL NOISE AND SAW SMOKE BILLOWING UNDER THE HOOD. I SHUT IT DOWN IMMEDIATELY KNOWING THAT WHAT WAS ABOUT TO HAPPEN COULDN'T BE GOOD. I WENT ONLINE AND FOUND OUT THIS HAS HAPPENED TO MANY CX7S NOW THE DEALER IS TELLING ME THAT BECAUSE I'VE OWNED THIS FOR 37 MONTHS, (35,000 MILES) THAT IT ISN'T COVERED BY THE 60,000 MILE DRIVE TRAIN WARRANTY, (IF I CAN'T DRIVE IT, ITS A DRIVETRAIN PROBLEM TO ME)...THIS NEEDS TO BE A CLASS ACTION LAWSUIT..OR A RECALL YOU'RE CHOICE. *TR

MAZDA DEALERSHIP WHERE VEHICLE WAS PURCHASED WAS LESS THAN A HALF MILE FROM FAILURE LOCATION AND AFTER TRAFFIC HAD DIED DOWN I WAS ABLE TO LIMP VEHICLE TO DEALER WITH WIFE FOLLOWING ME AT 10 MPH. TURBOCHARGER FAILURE HAS BEEN BLAMED, AS USUAL MAZDA HAS DENIED WARRANTY WORK DUE TO ENGINE SLUDGE, EVEN THOUGH VEHICLE HAS BEEN MAINTAINED. AFTER THOROUGH RESEARCH FOR THE LAST MONTH, WHILE MY VEHICLE HAS SAT AT THE DEALERSHIP,...
