2007 Mazda CX-7 Fuel system Problems

THE TIMING CHAIN TENSIONERS & BEARINGS THAT KEEP THE CHAIN TIGHT WEAR OUT WAY BEFORE THEIR LIFE SHOULD BE UP. I TOOK THE CAR TO THE MAZDA DEALERSHIP TO HAVE IT LOOKED AT & THE SHOP TECHNICIANS SAID THEY GET THIS PROBLEM WITH THESE CARS ALL THE TIME. ALL THEY HAD TO DO WAS LISTEN WHEN THE CAR WAS STARTED & THEY KNEW EXACTLY WHAT THE PROBLEM WAS. EVEN BEFORE GOING IN I CALLED & SPOKE TO A SERVICE TECH. AS SOON AS I SAID "MY CAR SOUNDS LIKE A DIESEL VEHICLE HE SAID OVER THE PHONE THAT THE PROBLEM WAS WITH THE TIMING CHAIN TENSIONERS AND SUCH. HE ALSO SAID MANY OF THE SAME CARS COME IN WITH THE SAME PROBLEM & HE COULDN'T UNDERSTAND WHY THERE WASN'T A RECALL ON THIS. THAT IS WHY I AM WRITING TO YOU. THE SOUND OCCURS WHEN THE ENGINE IS RUNNING REGARDLESS OF IF WE'RE IN MOTION OR NOT. IF YOU PUT MAZDA CX-7 SOUNDS LIKE A DIESEL IN A BROWSER SEARCH YOU WILL GET MANY RESULTS REGARDING THE TIMING CHAIN ISSUE.

TIMING CHAIN STRETCHED AND VARIABLE VALVE TIMING, AND THROTTLE WENT OUT. THIS IS THE 2ND TIME THAT THE TIMING CHAIN HAS BEEN STRETCHED OUT ON THIS VEHICLE. THE FIRST INCIDENT WAS AT AROUND 64000 MILES. THE 2ND INCIDENT WAS AT 124966 MILES. MAZDA EXTENDED THE WARRANTY ON THE TIMING TO 70,000 MILES ON JANUARY 12. HOWEVER, I DID NOT GET THAT LETTER AND IT HAPPENED AFTER I HAD ALREADY GOTTEN THE PROBLEM REPAIRED UNDER A SEPARATE WARRANTY. *TR

AIR BAG LIGHT COMES ON AND OFF RANDOMLY WITH OR WITHOUT PASSENGER IN SEAT. HAVE HAD SO MANY ISSUES WITH THIS 2007 CX-7 FROM 2 DIFFERENT COMPLETE A/C SYSTEM REBUILDS IN FIRST 2 YEARS, BELT TENSIONER PULLEY, EGR VALVE CODES (HAD TO GET EGR VALVE CLEANED), COOLANT TEMP CODES (REPLACED THERMOSTAT & TEMP SENSOR) AND NOW AIR BAG RANDOM LIGHT. I AM ON A MAZDA FORUM AND HONESTLY THERE SHOULD BE MORE RECALLS ON THIS VEHICLE DUE TO THE VOLUME OF COMPLAINTS IN SEVERAL CATEGORIES... MAZDA RESPONSES TO JUST ABOUT EVERYTHING IS TO REPLACE SOMETHING FOR A MINIMUM $500 UP TO THOUSANDS... I AM TIRED OF HAVING TO DEAL WITH MAZDA AND WILL NEVER BUY ANOTHER... TRADED IN A 2001 CHEVY TAHOE FOR CX-7 WITH 250,000 MI AND ONLY HAD NORMAL MAINTENANCE. THE CX-7 WAS A BAD INVESTMENT FOR ME... *TR

MY 2007 CX-7 STARTED MAKING A LOUD BANGING NOISE WHEN I STARTED IT (MAY 7,2012). I BROUGHT IT TO THE DEALERSHIP TO HAVE IT CHECKED OUT AND THEY SAID IT WAS MY TIMING CHAIN & ACTUATOR (VVT) AND IT WOULD TAKE $1350 TO REPAIR. I PAID THE MONEY AND IT WAS FIXED IN A COUPLE OF DAYS. ON JUNE 7TH,2012 I STARTED TO REALIZE THAT MY AC WAS NOT WORKING, BUT HAD DECIDED TO WAIT A LITTLE BIT TO HAVE IT FIXED BECAUSE I WAS STILL HURTING FINANCIALLY FROM THE LAST FIX A MONTH AGO. THAN ON JUNE 9TH, 2012, I WENT TO START MY VEHICLE AND IT SOUNDED LIKE IT WAS ABOUT TO EXPLODE. I LIVE IN THE COUNTRY AND THE CLOSEST DEALERSHIP IS AT LEAST 50 MILES AWAY. SO I BROUGHT IT TO MY LOCAL REPAIR SHOP AND THEY TOLD ME MY TURBO IS BLOWN. THE MAZDA DEALERSHIP WANTS $80 TO DIAGNOSE IT AND $5000 TO FIX IT (THAT DOESN'T INCLUDE MY TOWING FEES AND THE COST OF FIXING THE AC). I'VE READ ALL OF THE COMPLAINTS ONLINE AND EVERYONE IS SAYING SLUDGE BUILD UP AND MAZDA WANTS THE RECEIPTS FOR ALL OF THEIR OIL CHANGES. I HAVE ALL MY RECEIPTS FOR THE SYNTHETIC OIL CHANGES THAT I HAVE HAD DONE TO THE VEHICLE ON TIME (NOT TO MENTION ONLY FILLING THE CAR WITH PREMIUM GAS). UNFORTUNATELY, MY CAR IS UP TO 100,000 MILES AND THEY ONLY EXTENDED THE WARRANTY TO WHAT...70K? SO BASICALLY I HAVE A CAR THAT I PAID $16K FOR AND IS COMPLETELY USELESS TO ME ONLY AFTER 100K MILES. FROM WHAT I'VE RESEARCHED VVT'S ARE NOT SUPPOSED TO GO OUT UNTIL WHAT 250K-300K MILES? AND IT SEEMS A BIT RIDICULOUS FOR THE TURBO TO GO OUT AFTER 100K MILES.... *TR

THIS VEHICLE HAS CAUSED ME NOTHING BUT PROBLEMS! I HAVE HAD IT FOR 3 YEARS AND IT HAS BEEN IN THE SHOP 4 TIMES AND THIS LAST TIME IS THE TRANSMISSION AT 70,000 MILES! THIS IS RIDICULOUS...MAZDA NEEDS TO CLEAN UP IT'S ACT. CUSTOMERS SHOULD NOT HAVE CHARGES LIKE THIS EARLY ON IN THE LIFE OF A VEHICLE. THE VEHICLE IS GORGEOUS BUT PERHAPS THEY SHOULD HAVE SPENT A LITTLE MORE TIME PUTTING IT TOGETHER AS IT DOESN'T MATTER FOR EYE APPEALING IT IS WHEN IT DOESN'T RUN! *TR

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

FOR QUITE AWHILE I HAD BEEN HEARING A "TICKING" NOISE WITH MY 2007 MAZDA CX-7..BROUGHT IT TO THE DEALERSHIP IN LAFAYETTE, LA. TO HAVE IT CHECKED OUT. THEY CHECKED IT OUT, UPDATED RECALLS IN AFFECT, STATED THEY FOUND NOTHING. CONTINUED TO HEAR IT OFF AND ON, HAD MY OIL CHANGED REGULARLY. ON JULY 10, 2010 MY CAR BROKE DOWN (4 YRS OLD, 33,000 MILES) HAD IT TOWED TO DEALER IN BEAUMONT, CLOSE TO WHERE IT HAD BROKEN DOWN. THE SERVICE DEPT. ASKED FOR MY SERVICE RECORDS AFTER IT WAS DETERMINED THAT PROBLEM WAS WITH THE ENGINE.. DID NOT HAVE EVERY RECEIPT DUE TO DEALER IN AREA CLOSING WITH NO RECORDS THERE, BUT PROVIDE THE LAST FEW.. AFTER TAKING AN "IMAGE" AND SENDING IT TO MAZDA, IT WAS DETERMINED THEY WOULD NOT HONOR THE WARRANTY BECAUSE I HAD EXCESSIVE "SLUDGE" AND WANTED ME TO PAY FULL COST OF A NEW ENGINE/MOTOR. NO ONE WANTED TO LISTEN TO ME..I DO REMEMBER THAT WHEN MY OIL WAS CHANGED, THE MECHANIC HAD TOLD ME IN THE PAST THAT IT SEEMED TO HAVE "SLUDGE", BUT THAT WAS ONLY BETWEEN 3,000 MILES. I HAD TAKEN CARE OF MY CAR, AND THEY WERE TELLING THAT IT HAD "POOR MAINTENANCE" AND WOULD NOT HONOR THE WARRANTY! *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 SOMETHING WRONG AND DECIDED THEY WERE NOW NOT GOING TO HELP AT ALL. THAT IS JUST POOR CUSTOMER SERVICE BEHIND A VEHICLE THAT WAS NOT READY TO BE PUT ON OUR US ROADWAYS. IN MY OPINION, THIS CAR SHOULD BE RECALLED. AFTER REVIEWING SOME OF THE FORUMS, MANY OTHERS AGREE WITH MY DISPLEASURE IN THE PROBLEMS WITH THE MAZDA CX-7--CHECK THIS LINKHTTP://TOWNHALL-TALK.EDMUNDS.COM/DIRECT/VIEW/.F0E5B59/110. THANK YOU. *JB
