2007 Mazda Mazda5 Engine Problems

I was driving my Mazda 5 2007 in traffic when suddenly it burst into flames on the passenger side underneath the hood

CAR STOPS RUNNING WITH NO FAULT APPEARING. HAPPENED AT ABOUT 17000 MILES. COMPUTER (PCM) REPLACED. HAPPENED AGAIN AT 70000 MILES. PCM REPLACED. DID NOT CORRECT PROBLEM. DEALER HAS HAD CAR OVER 5 WEEKS. CAN NOT DETERMINE FAULT. CAR IS DANGEROUS TO DRIVE. EACH EVENT HAPPENS REPEATEDLY ON HIGHWAY. VERY DANGEROUS. COULD EASILY RESULT IN FATAL ACCIDENT

CHECK ENGINE LIGHT CAME ON THE NIGHT BEFORE. THE NEXT MORNING MY WIFE WENT TO RUN AN ERRAND BEFORE GOING TO CHECK THE CAR OUT AT THE DEALERSHIP, BUT SHE ONLY GOT ABOUT 13 MILES WHEN THE ENGINE BLEW OUT AND STARTED SMOKING. THE VEHICLE HAD APPROX 56K MILES AND THE ENGINE SHOULD HAVE BEEN COVERED UNDER WARRANTY, BUT THE DEALERSHIP STATES THAT IT WAS NOT COVERED ANYMORE BECAUSE WE RAN THE VEHICLE THAT MORNING WITH THE CHECK ENGINE LIGHT ON. THE DEALERSHIP STATED THAT THE ENGINE WAS COMPLETELY BLOWN AND THAT IT OVERHEATED. THEY STATE THAT THERE WAS NO COOLANT IN IT. THERE WAS NO PRIOR LEAK IN THE COOLANT, AND THE COOLANT WAS CHECKED AND REFILLED ONLY 2 WEEKS PRIOR. WE WOULD HAVE NOTICED A COOLANT LEAK ON OUR DRIVEWAY. *TR

WE PURCHASED OUR 2007, MAZDA 5 NEW IN JAN. 2007 FROM A LOCAL DEALERSHIP. AT A LITTLE OVER 9,000 MILES THE CAR BEGAN TO HESITATE AND WE RETURNED TO THE DEALERSHIP FOR THE FIRST SERVICE TO "FIX" THE PROBLEM. TO FAST FORWARD, HERE WE ARE DEC. 31ST, 2011 AND NOW WE ARE DEALING WITH NOT ONLY HESITATION AND STALLING, BUT NOW THE CAR ACTUALLY "BUCKS" WHILE DRIVING IT ONLY ADDING TO THE DANGERS OF DRIVING IT. THIS IS A WELL DOCUMENTED PROBLEM AS WE HAVE CONTINUED TO RETURN IT THE SAME DEALERSHIP EACH TIME ONLY TO BE TOLD IT WAS "FIXED". THIS HAS BECOME A SAFETY CONCERN, AND A FINANCIAL WOE. WHY THE LACK OF CONCERN BY MAZDA AND OTHER AGENCIES THAT KNOW OF THIS PROBLEM BUT HAVE NOT MADE MAZDA ADMIT THE PROBLEM AND RECALL THESE CARS BEFORE SOMEONE IS KILLED. NOT EVERYONE IS IN THE POSITION TO JUST BUY ANOTHER CAR IF THEY SEEM TO HAVE A "LEMON". I WOULD REALLY LIKE TO KNOW MY RECOURSE IN ALL OF THIS....TO DRIVE A UNSAFE CAR?, TO HOPE I OR A FAMILY MEMBER WON'T BE HURT OF KILLED IN IT UNTIL SUCH TIME I CAN TRADE IT IN? AND THEN FEEL GUILTY THAT SOME OTHER PERSON IS PURCHASING MY UNSAFE CAR? I HOPE THAT THERE IS "SOME HOPE" BY CONTACTING YOUR AGENCY. IF NOTHING ELSE IF YOU WON'T HELP ME, MAYBE I CAN WARN SOMEONE ELSE ABOUT THIS CAR. *KB

I PURCHASED A 2007 MAZDA 5. THIS IS A DECENT CAR BUT AT COLDER TEMPERATURES THE VEHICLE WILL STALL AND SHUTTER ABOUT 1-3 MINUTES AFTER START UP. THE COLDER IT GETS AND THE MORE MILES THAT THE CAR GETS ON IT THE MORE OFTEN THIS OCCURS. THE DEALERSHIP TOLD ME THAT THIS IS A COMMON ISSUE AND THAT MAZDA HAS TOLD THEM TO FLASH AGAIN THE COMPUTER. THAT WAS DONE AND DID NOT FIX THE ISSUE. IT IS VERY DANGEROUS IF I PULL OUT IN TRAFFIC AND THIS VEHICLE FAILS I AM HAULING MYSELF AND MY HUSBAND AND 4 KIDS THAT IS GOING TO BE SOMETHING THAT IS MAZDA'S FAULT FOR NOT REMEDYING THE SITUATION. THIS NOW OCCURS AFTER DRIVING AND COMING TO A SLOW OR A STOP. ALSO WHEN THE TEMPERATURES ARE FROM 35-40 DEGREES THE FRONT RIGHT WHEEL MAKES AN AWFUL NOISE SOMETIMES SQUEAKING AND THEN SOMETIMES A GRINDING NOISE. THE DEALERSHIP INFORMED ME THAT IT IS "HEAVY, AND EXCESSIVE GREASE IN THE BALL JOINT". NOW THAT THE TEMPERATURE IS WARMER YOU CANNOT HEAR THIS ANYMORE. THE VEHICLE HAS 13,000 MILES AND WHILE DRIVING ON THE INTERSTATE AT 60-65 MPH AND YOU PUT ON THE BRAKES THE STEERING WHEEL SHAKES AND ACTS AS IF THE BRAKES ARE WARPED. WHEN THE TEMPERATURE IS HOT OUTSIDE THE A/C WORKS POORLY WITH A TEMP OUT OF THE VENTS AT 47 DEGREES. WHEN STOPPING AT A DRIVE THROUGH RESTURANT OR AT THE BANK THE SMELL OF BURNING ANTIFREEZE IS VERY NOTICABLE. THERE IS NO VISABLE LEAKS BUT THE SMELL OF ANTIFREEZE IS EVIDENT. THIS IS A POOR DESIGNED, OVERPRICED, NOT ADVERTISED VEHICLE THAT MAZDA SHOULD WORK OUT THE BUGS IN, OR GIVE THE MONEY BACK TO THE CUSTOMERS. THIS CAR HAS BEEN IN THE SHOP 7 TIMES SINCE NEW FOR THESE ISSUES THAT MAZDA SAID THEY DONT KNOW HOW TO FIX YET. I HAVE GIVEN THEM TIME AND THE OPPORTUNITY NOW MY LEMON LAW WILL BE RUNNING OUT AND I DONT WANT STUCK WITH A LEMON. *AK
