ENGINE

I RECENTLY PURCHASED A '03 MAZDA PROTEGE5. WHILE DRIVING DOWN THE ROAD YESTERDAY AT 65 MPH, I HEARD A LOUD BANG AND HEARD SOMETHING HIT THE BOTTOM OF THE CAR. THE CAR EXHAUST SUDDENLY BECAME MUCH LOUDER. I IMMEDIATELY PULLED OFF THE ROAD. I LOOKED UNDER THE CAR, AND THE EXHAUST HAD COME APART. THE PIECE OF THE EXHAUST AFTER THE CAT WAS HANGING ABOUT 1 INCH FROM THE GROUND. THIS PIECE IS AFTER THE CATALYTIC CONVERTER, NEAR ONE OF THE HANGING POINTS OF THE EXHAUST SYSTEM. TWO BOLTS, WHICH HOLD THIS PIECE TOGETHER, AND THE EXHAUST GASKET WERE MISSING. LUCKILY, THERE WAS NO DAMAGE WHATSOEVER. THIS PROBLEM COULD HAVE ENDED TRAGICALLY.

ENGINE

ON AT LEAST 3-5 OCCASIONS THIS 2.0L ENGINE HAS SUFFERED THE EXACT SAME FATE AS NHTSA ID# 10422484. CHECK ENGINE LIGHT ON, MISFIRING, ASSOCIATED NOISE SOUNDING LIKE A BOLT / SCREW BOUNCING AROUND IN THE ENGINE FOR MAYBE 15 SECONDS, THEN WOULD RETURN TO NORMAL. EACH TIME THERE HAS BEEN A DIFFERENT CYLINDER MISFIRE, UPON SPARK PLUG REMOVAL IT WAS FOUND THE GAP WAS CLOSED CAUSING NO SPARK. EACH TIME, A NEW PLUG WAS INSTALLED AND CORRECTED THE IMMEDIATE PROBLEM. AFTER SEEING THESE COMPLAINTS AND A RECALL REGARDING THIS ISSUE I REALIZED I'VE HAD THE SAME ISSUE. DON'T KNOW IF MY VIN # IS IN THE EFFECTED RANGE OR NOT. CAR NOW HAS 123105 MILES. WOULD HOPE THAT MAZDA WOULD COVER ANY VEHICLE WITH THIS PROBLEM.

ENGINE AND ENGINE COOLING

MY 03 PROTEGE HAS VICS SCREWS FALLING OUT AND ALL ISSUES THAT COMES WITH IT. MY CAR HAS BEEN PARKED IN THE DRIVEWAY UNTOUCHED BECAUSE I CANNOT AFFORD TO PAY FOR THE REPAIRS DUE TO HOW MANY TIMES MY CAR HAS HAD ISSUES AND CANNOT PASS EMISSIONS. SO I HAVE TO TURN MY TAGS IN WITHIN THE MONTH BECAUSE MAZDA WONT RECOGNIZE THE ISSUE BEING THEIR RECALL SINCE MY VIN IS OUT OF THEIR WINDOW FOR CARS BEING DEFECTIVE. I DON'T UNDERSTAND WHY IF SO MANY PEOPLE ARE HAVING THE SAME PROBLEM; WHY THOSE MONTHS WHEN WE HAVE THE SAME PARTS? MAZDA CLAIMS ITS THE TORQUE BUT OBVIOUSLY ITS THE SCREWS FALLING OUT INCLUDING THE BUTTERFLIES. WHY WAS THE TORQUE DIFFERENT THOSE 3 MONTHS? IF MAZDA IS SAYING THE RECALL IS DUE TO THE TORQUE BEING WRONG AND THE SCREWS ARE FALLING OUT THEN WHY ARE SO MANY VEHICLES THAT ARE IN AND OUT OF THE VIN NUMBER NEEDED TO BE REQUIRED FOR FREE REPAIR? WHY ARE SO MANY VEHICLES BEING CHECKED AND MECHANICS FINDING SCREWS AND BUTTERFLIES IN OTHER AREAS OTHER THAN WHERE THEY SHOULD BE? IF THE RECALL IS DUE TO TORQUE, THEN WHY ARE YOU REPLACING THE ORIGINAL SCREWS? IF TORQUE IS THE CASE WHY NOT JUST USE THE CORRECT TORQUE USAGE, YOU KNOW THE TORQUE THAT'S IN MY CAR! WHY ARE PROTEGES WITH THE VINS OUT OF THE RECALL WINDOW HAVING THE SAME CORRECTIVE ACTION WHEN THEY GO TO GET THE REPAIR AND GET THE SAME PARTS WHEN THEY HAD THE CORRECT TORQUE IN THE FIRST PLACE! ITS CLEAR THIS RECALL ISN'T ABOUT TORQUE, THIS IS ABOUT IT THE RECALL PART BEING FAULTY NO MATTER WHAT TORQUE WAS USED. WOULDN'T IT HAVE BEEN MORE COST EFFECTIVE AND EASIER FOR YOU JUST TO USE THE REQUIRED TORQUE RATHER THAN NEW PARTS SINCE YOU SAY. MAZDA DOESN'T TAKE THIS SERIOUSLY AND FIX THEIR FAULTY PART. WE NEED HELP!

ENGINE AND ENGINE COOLING:ENGINE

WHILE DRIVING ON HIGHWAY AT ABOUT 60 MPH FOR 40 MINUTES, THE CAR BEGAN SPUTTERING, JERKING, MAKING NOISES, LOSING ACCELERATION AND THE CHECK ENGINE LIGHT CAME ON. IT INITIALLY FELT LIKE SOMEONE WAS TAKING THEIR FOOT ON AND OFF THE GAS. WE PULLED OFF ROAD AND WERE TOWED TO OUR GARAGE. MECHANIC FOUND THAT THE SPARK PLUG FOR CYLINDER 4 WAS SMASHED SHUT, HE REPLACED IT AND TOLD US TO TAKE IT TO THE DEALER SINCE THIS WAS THE 3RD TIME WE HAD THIS PROBLEM. IN DEC OF 2009 THE SPARK PLUG FOR CYLINDER 1 HAD SAME PROBLEM THEN AGAIN IN FEB 2010 IT WAS THE PLUGS FOR 1 & 4. EACH TIME WE WERE DRIVING AT 55 MPH OR HIGHER WHEN CAR BEGAN TO SPUTTER THEN CHECK ENGINE LIGHT CAME ON. MAZDA IS TELLING US NOTHING IS IN THE ENGINE, THE COMPRESSION IS FINE AND THEY HAVE NO IDEA WHY SPARK PLUGS ARE GETTING SMASHED. THE FIRST TIME IT HAPPENED OUR MECHANIC THOUGHT IT WAS BAD SPARK PLUG AND REPLACED IT FREE OF CHARGE, THE SECOND TIME WE TOOK IT TO THE DEALER WHO COULD FIND NOTHING. IT IS NOW AT THE DEALER AGAIN AND THEY ARE SAYING THE ONLY THING THEY COULD DO IS TAKE THE ENGINE APART AND LOOK BUT HAVE NO GUARANTEE OF FINDING ANYTHING AND IT COULD COST $1500. THEY REMOVED SPARK PLUG, CHECKED FOR DEBRIS AND TESTED THE COMPRESSION. THEY ALSO USED A MAGNET TO SEARCH FOR FOREIGN BODY IN CYLINDER AND FOUND NOTHING.

ENGINE AND ENGINE COOLING:ENGINE

MY 2002 PROTEGE 5 (BUILT DECEMBER 2002) HAD A CATASTROPHIC ENGINE FAILURE, DUE TO LOOSE VICS SCREWS FROM THE INTAKE MANIFOLD COMING LOOSE AND BEING SUCKED INTO THE COMBUSTION CHAMBER. THESE SCREWS SHEARED OFF THE TOP OF MY SPARK PLUG, AND DESTROYED MY PISTON AND VALVES. THE OUTWARD SYMPTOMS WAS A LOUD 'COIN IN THE WASHING MACHINE' SOUND COMING FROM MY ENGINE, FOLLOWED BY A SUDDEN LOSS OF POWER AND STALLING. AFTER THE ENGINE WAS OPENED, 3 OF 8 VICS SCREWS WERE OFF COMPLETELY, AND THE REMAINING 5 WERE LOOSE. THIS IS CLEARLY THE IDENTICAL DEFECT TO A RECALL FOR PROTEGE 5'S BUILT SHORTLY AFTER MY VEHICLE (EMISSIONS RECALL 3005C), BUT MY VEHICLE WAS NOT COVERED IN THE RECALL. READING ONLINE BOARDS FOR PROTEGE OWNERS, IT IS CLEAR THAT THIS IS A FREQUENT DEFECT EFFECTING BOTH OWNERS IN AND OUT OF RECALL RANGE, AND THAT THIS VICS RECALL SHOULD BE WIDENED TO INCLUDE ADDITIONAL OWNERS. QUOTES FROM MAZDA FOR REPAIR ARE ~$5000 FOR A NEW INTAKE MANIFOLD, VALVES AND PISTONS, AND LABOR TO REPAIR.

WHILE DRIVING TO WORK MY CAR BEGAN TO SHUDDER AND HICCUP. THEN THE ENGINE LIGHT CAM ON SO I PULLED OFF THE HIGHWAY. I STARTED IT BACK UP AND THE CAR HAD A MORE SERIOUS SHUDDER. I GOT IT TO A LOCAL SERVICE STATION AND THEY RAN A COMPUTER DIAGNOSTIC AND SAID IT WAS A MISFIRE IN THE #4 CYLINDER. THE SPARKPLUG WAS SMASHED. NOTHING WAS FOUND IN THE CYLINDER SO THE SPARKPLUG WAS REPLACED AND TEMPORARILY FIXED THE PROBLEM. TWO WEEKS LATER THE SAME SHUDDER PROBLEM AND AGAIN THE ENGINE LIGHT CAME ON.

PURCHASED A PRE OWNED 2003 MAZDA PROTEGE WITH APPROXIMATELY 50,000 MILES ON IT. I DROVE THE VEHICLE FOR ABOUT 4000 MILES BEFORE THERE WAS AN ENGINE FAILURE.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL

WHILE DRIVING NORMALLY TO MY HOME AFTER WORK THE CAR STALLED AT A STOP LIGHT. )WHEN RESTARTED THERE WAS A LOUD CLANKING/HAMMERING NOISE FROM THE ENGINE FOR ABOUT 15 SECONDS THEN THE SOUND WENT AWAY, THE CELL LIT UP AND THE ENGINE STARTED SHAKING. WHEN CHECKED FOR CODES A MISFIRE ON CYLINDER -4 WAS FOUND. (THE SPARK PLUG ON CYLINDER 4 HAD BEEN SMASHED FLAT BY A FOREIGN OBJECT THAT CAUSED THE HAMMERING NOISE, NOTHING WAS FOUND INSIDE THE CYLINDER , USING A MAGNET. THE SPARK PLUG WAS REPLACED AND THE CAR WORKED AS NORMAL. UPON INVESTIGATION ON THE INTERNET I FOUND RECALL 3005C FOR THE VEHICLE THAT DESCRIBES MY PROBLEM AND IF NOT FIXED CAN CAUSE ENGINE FAILURE. WHEN CONTACTING MAZDA CUSTOMER ASSISTANCE THEY SAID MY VIN WAS NOT IN RANGE FOR THIS RECALL AND THAT I WOULD HAVE TO PAY FOR ANY REPAIRS BECAUSE MY CAR HAS 61000 MILES AND EVEN THOUGH THE EMISSIONS WARRANTY IS STILL ACTIVE, THE REGULAR WARRANTY IS OVER.

ENGINE AND ENGINE COOLING:ENGINE

I PURCHASED VEHICLE NEW IN JAN 04. WHILE EXITING THE FREEWAY, I FELT A "HICCUP" IN THE ENGINE AT WHICH TIME IT RAN VERY POORLY AND CHECK ENGINE LIGHT CAME. THE SERPENTINE BELT HAD ALSO JUMPED ABOUT 25% OFF DRIVE PULLEYS. I WAS TRAVELING OUT OF TOWN AT THIS TIME AND TOOK IT TO A LOCAL SERVICE STATION. TECHNICIAN IDENTIFIED PROBLEM AS AN ENGINE MISFIRE AND INSTALLED A NEW BELT. I DECIDED NOT TO HAVE SERVICE STATION PERFORM ANY ADDITIONAL DIAGNOSIS PREFERRING TAKE VEHICLE TO DEALERSHIP INSTEAD. DEALERSHIP DETERMINED THAT A SPARK PLUG HAD FAILED AND CAME APART. DEALERSHIP THEN REPLACED ALL SPARK PLUGS. VEHICLE RAN FINE. APPX 1 MONTH LATER, EXACT SYMPTOMS OCCURRED - ENGINE HICCUP, ROUGH IDLE, CHECK ENGINE LIGHT. AGAIN I TOOK TO DEALERSHIP. MASTER TECH WAS ASSIGNED TO MY VEHICLE THIS TIME AND DETERMINED CAUSE TO BE SHUTTER VALVE SCREWS HAD COME LOOSE FROM THE INTAKE MANIFOLD AND ENTERED ENGINE CAUSING DAMAGE TO SPARK PLUG. TECHNICIAN INFORMED ME OF RECALL # 3005C THAT HAD BEEN ISSUED AND THAT HE WOULD CONTACT HIS REGIONAL SERVICE MANAGER TO REQUEST THE REPAIR BE COVERED BY MAZDA. REGIONAL SVC MGR DECLINED TO COVER COSTS STATING MY SPECIFIC VIN WAS NOT IN THE EFFECTED RANGE AND THAT MY MILEAGE WAS TOO HIGH. I LOOKED UP THE RECALL AND DETERMINED THE RECALL ISSUE DATE TO BE 6/1/05. AT THAT TIME MY MILEAGE WOULD HAVE BEEN 40,000 TO 50,000 MILES. I THEN CONTACTED MAZDA USA CUSTOMER ASSISTANCE - REFERENCE NUMBER 112751060. I WAS TOLD THAT MAZDA WOULD NOT COVER THE EXPENSE BECAUSE MY VIN # WAS NOT IN THE RANGE OF EFFECTED VEHICLES. I WAS ALSO TOLD THAT VIN RANGE WAS DETERMINED BY THE NHTSA AND NOT BY MAZDA AND THAT IT WAS ILLEGAL FOR MAZDA TO PAY FOR THE REPAIR EXPENSE. I BELIEVE THIS TO BE A LIE ON THE PART OF MAZDA. I BELIEVE MAZDA IS NOT ACCEPTING ITS' RESPONSIBILITY TO THE CONSUMER BECAUSE THIS WOULD BE ADMITTING THE PROBLEM IS LARGER THAN THE ORIGINAL SCOPE AND WILL COST THE COMPANY A SUBSTANTIAL AMOUNT OF MONEY.

ENGINE AND ENGINE COOLING:ENGINE

FOR OVER TWO AND A HALF YRS, MY CAR HAS HAD A ROUGH IDLING NOISE AND THE ENGINE OFTEN HESITATES AND WANTS TO TURN OFF. ON SEVERAL OCCASIONS THE ENGINE HAS HESITATED AND SHUT THE CAR OFF. VERY RECENTLY A LOUD NOISE WAS COMING FROM MY ENGINE. (YOU COULD HEAR A RATTLING NOISE) IT SOUNDED LIKE A PIECE OF METAL RATTLING AROUND IN THE ENGINE. A YEAR AGO I TOOK MY CAR INTO THE DEALERSHIP BECAUSE OF A RECALL (RECALL 3005C) TO GET IT CHECKED OUT (THIS IS WHAT THE LETTER FROM MAZDA ASKED ME TO DO) MY CAR WAS THERE ONLY TWO HOURS AND ONLY LOOKED AT MAYBE ABOUT THIRTY MINUTES. I RECEIVED AN OIL CHANGE AND THEN THEY WERE TO INSPECT IT DUE TO THE RECALL. WHEN I RETRIEVED MY CAR THEY GAVE ME A CERTIFICATE OF CORRECTION, BUT INFORMED ME THAT NOTHING HAD BEEN FIXED AND THAT THEY WERE ONLY AUTHORIZED TO INSPECT. THAT IF THE PART BROKE THAT I WOULD BE RESPONSIBLE FOR IT EVEN THOUGH IT WAS A RECALL. HERE I AM ONE YEAR LATER AND I HAD MY CAR LOOKED AT AND IT APPEARS THAT TWO OF THE SCREWS MUST HAVE COME LOOSE DUE TO THE RECALL. (THEY WERE FOUND IN MY EXHAUST) I GOT NO HELP FROM THE DEALER. I FOUND THE RECALL INSTRUCTIONS ONLINE FROM MAZDA TO THE DEALER WHICH INSTRUCTS THE DEALER TO REPLACE THE PARTS IF THEY HAVE NOT BEEN REPLACED ON ANY PREVIOUS OCCASION (WHICH WAS PROCEDURE B). AND IF IT HAS BEEN PREVIOUSLY WORKED ON THEY ARE TO PROCEED WITH PROCEDURE A WHICH INSTRUCTS THEM TO DO AN AIR COMPRESSION INSPECTION FOR INTERNAL DAMAGE AND GIVE A CERTIFICATE OF CORRECTION. THEY DID THE WRONG PROCEDURE ON MY CAR AND NEVER ACTUALLY DID WHAT NEEDED TO BE REPLACED FOR MY CAR TO BE LEGAL AND OK TO DRIVE. THEY ARE NOW AVOIDING MY CALLS AND NOT RETURNING NUMEROUS E-MAILS OR VOICE MAILS. I HAVE BEEN TRYING THE DEALER AND MAZDA THEMSELVES. ON TUES .I RECEIVED NOTHING BUT RUDE MOCKING FROM EACH PLACE TELLING ME THAT IT WAS MY PROBLEM. I HAVE BEEN TRYING EVERYDAY SINCE AND I HAVE RECEIVED NO RESPONSE. *NM UPDATED 2/23/2007 - INTAKE MANIFOLD SHUTTER AND VARIABLE TUMBLE CONTROL VALVES.

ENGINE AND ENGINE COOLING

MY ENGINE FAILED CAUSING A SUDDEN LOSS OF POWER. I WAS ABLE TO PULL OVER SAFELY. MY CAR REQUIRED ABOUT $1,000 WORTH OF REPAIRS, USING USED PARTS, AND I HAVE PERMANENT ENGINE DAMAGE THAT WILL ULTIMATELY SHORTEN THE LIFE OF MY ENGINE. THE ROOT CAUSE OF THE ENGINE FAILURE WAS DUE TO LOOSE SCREWS LOCATED IN THE AIR INTAKE MANIFOLD, THAT ALLOWED FOR A BAFFLE OR BUTTERFLY VALVE TO BREAK AND ENTER MY ENGINE. THIS VERY SAME PROBLEM WAS RECALLED BY MAZDA FOR VEHICLES MADE FROM MARCH OF 2003 TO JULY OF 2003, MINE WAS MANUFACTURED IN FEBRUARY OF 2003, AND THEREFORE WAS NOT RECALLED. I KNOW OF AT LEAST THREE OTHER PEOPLE WHO ALSO HAVE EXPERIENCED THIS VERY SAME ISSUE WHO HAVE NOT BEEN INCLUDED IN THE RECALL. I HAVE HAD TWO SEPARATE MAZDA SERVICE MANAGERS CONFIRM THIS WAS THE SAME PROBLEM AS THE RECALL - LOOSE SCREWS IN AIR INTAKE MANIFOLD. I NEED THIS INVESTIGATED TO DETERMINE IF MORE CARS SHOULD BE RECALLED.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

DT*: THE CONTACT STATED WHILE DRIVING 30MPH, THERE WAS A RATTLING NOISE FROM THE ENGINE COMPARTMENT FOLLOWED BY THE ENGINE STALLING. THE VEHICLE WAS TOWED TO AN INDEPENDENT REPAIR SHOP FOR INSPECTION. THE MECHANIC DETERMINED THE SCREWS USED FOR MOUNTING THE INTAKE MANIFOLD SHUTTER VALVE BROKE AND FELL INTO THE CATALYTIC CONVERTER AS WELL AS THE OIL PAN AND PISTONS. THE VEHICLE IS SCHEDULED FOR REPLACEMENT OF THOSE SCREWS. THERE IS AN EMISSION RECALL, #3005C, REGARDING THE EXHAUST SYSTEM. THE VEHICLE HAS THE SAME PROBLEMS AS INDICATED IN THE RECALL; HOWEVER IT IS NOT INCLUDED IN THE RECALL DUE TO THE VIN.

ENGINE AND ENGINE COOLING:ENGINE:GASOLINE

ONE OF THE BUTTERFLY VALVES ON THE INTAKE MANIFOLD FELL OFF COMPLETELY. THIS HAPPENED WHEN THE LAST OF THE TWO SCREWS HOLDING IT ON CAME LOOSE AND FELL-OFF AND WAS SUCKED INTO THE ENGINE. WHEN THE PART WAS DISMANTLED, THERE WERE ONLY FIVE OF THE ORIGINAL EIGHT SCREWS REMAINING. ONLY ONE OF THE FOUR VALVES WAS COMPLETELY CONNECTED WHEN THE UNIT WAS OPENED. I WAS DRIVING NORMALLY DOWN ROAD AND LUCKILY THIS HAPPENED AS I WAS PARKING MY CAR. THE EVENT HAPPENED ON 7/22/05 AND THE MAZDA DEALERSHIP STATED THAT ALTHOUGH THEY HAVE SEEN THIS OCCUR BEFORE, THERE IS NO TSB OR RECALL. I WILL NEED TO REPLACE THIS PART OF THE MANIFOLD AT A COST OF MORE THAT $1000 DOLLARS. ON A MAZDA ENTHUSIST WEBSITE THAT I FREQUENT, AT LEAST TEN OTHER MEMBERS HAVE HAD THE SAME PROBLEM WITH RESULTS VARYING FROM COMPLETE ENGINE REPLACEMENT, TO THE SAME SUPPOSED FIX AS I NEED. THAT INFORMATION CAN BE FOUND AT "WWW.PROTEGE5.COM" THE INFORMATION IS AVAILABLE IN NUMEROUS PLACES IF YOU SEARCH THERE FOR "ENGINE NOISE."
