2006 Hummer H3

FIRST OF ALL, THE DATE OF THE INCIDENT IS VERY VAGUE CONSIDERING IT'S BEEN HAPPENING MOST OF THE LIFE SPAN OF THE VEHICLE. EVER SINCE THE VEHICLE REACHED 30,000 MILES THE CHECK ENGINE LIGHT HAS BEEN GOING ON AND OFF PERIODICALLY. NOW THERE IS AROUND 85,000 MILES AND I CAN HONESTLY SAY THE CHECK ENGINE LIGHT HAS BEEN ON FOR MOST OF THE LIFE OF THE CAR. THE CODE IS ALWAYS P0300. THIS IS DUE TO A RANDOM MISFIRE IN THE CYLINDER HEADS. I HAVE HAD THIS CAR LONG ENOUGH TO SAY THIS TYPICALLY HAPPENS DURING IDLE. THIS CAR HAS ALWAYS HAD A ROUGH IDLE. I WOULD SAY TEN PERCENT OF THE TIME IT'S A SMOOTH IDLE. I ALWAYS USE GOOD GAS, CLEAN OIL AND UP TO DATE MAINTENANCE ON THIS VEHICLE AND I NEVER STRESS THE ENGINE DUE TO IT'S FEELING OF IT BEING SO FRAGILE. GOING ONLINE I AM ASTONISHED TO FIND SO MANY WITH THE SAME EXACT PROBLEM. GM HAD THE SAME RECALL ON THE INLINE 5 CYLINDER CANYON CYLINDER HEADS. THIS IS THE SAME PROBLEM WE ARE HAVING WITH OUR INLINE 5 CYLINDER ENGINE HEADS. GM NEEDS TO PUT THIS ON RECALL. FIX THEIR MISTAKE AND KEEP THIS CHECK ENGINE LIGHT FROM GOING ON EVERY TIME I PARK MY CAR, START MY CAR OR SIMPLY IDLE. MANY WOULD BE GRATEFUL IF THIS WAS RECALLED. *TR

TL* THE CONTACT OWNS A 2006 HUMMER H3. THE CONTACT STATED THAT THE VEHICLE WOULD NOT ACCELERATE OVER 50 MPH. IN ADDITION, THE VEHICLE WOULD SPORADICALLY STALL WITH THE ILLUMINATION OF THE CHECK ENGINE WARNING LIGHT ILLUMINATED. ALSO, THE VEHICLE WOULD OVERHEAT WHEN THE FAILURE OCCURRED. THE VEHICLE WAS TAKEN TO A MECHANIC WHERE A DIAGNOSTIC WAS PERFORMED. THE DEALER ADVISED THAT THE CATALYTIC CONVERTER, AIR SENSOR, COIL SPRINGS, AND THE SPARK PLUGS NEEDED REPLACING. THE VEHICLE WAS REPAIRED BUT THE FAILURE PERSISTED. THE FAILURE MILEAGE WAS 80,000 AND THE CURRENT MILEAGE WAS 87,000.

THE CHECK ENGINE CAME ON AND I TOOK IT TO MY DEALERSHIP TO HAVE IT CHECKED OUT.THEY PERFORMED A DIAGNOSTIC THAT LOCATED THE FAILURE AT THE ENGINE HEAD CYLINDER (ENGINE MISSFIRE). THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND DENIED ASSISTANCE WITH THE REPAIR BECAUSE THE VEHICLE WARRANTY WAS EXPIRED. THE MECHANIC STATED IT WAS DUE TO AN INFERIOR SOFT METAL USED TO MANUFACTURE THE HEADS WHICH CAUSED A LOSS OF COMBUSTION WHEN THE ENGINE WAS IDLING. THE BLOWBACK AT IDLE WAS WHAT WAS CAUSING THE ENGINE LIGHT TO ILLUMINATE. MECHANIC ALSO STATED THIS PROBLEM WAS A RECURRING PROBLEM IN THIS 5CYL ENGINE WHICH IS THE SAME ENGINE THAT IS IN THE COLORADO PICKUPS AND IS COVERED UNDER A GM RECALL IN THE PICKUPS BUT NOT THE HUMMER. THE MECHANIC STATED THAT THE ISSUE WILL ONLY GET WORST. PLEASE HELP AS I WAS GIVEN A PRICE TO REPAIR OF APPROX. $3183 IF I WAS GOING TO PAY FOR THE REPAIRS MYSELF AT THE DEALERSHIP. WHAT CAN A PERSON DO WHEN THIS IS A KNOWN MFG DEFECT, MANY COMPLAINTS ABOUT THIS ISSUE WITH NO RECOURSE. *TT

THE CONTACT STATED THAT THE TEMPERATURE GAUGE HAD INCREASED SEVERAL TIMES AND WHEN HE INSPECTED THE VEHICLE, HE FOUND RADIATOR COOLANT LEAKING FROM THE RADIATOR TOP SEAL. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE HE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 83,000.

I WENT IN TO DEALER FOR WHAT I CALLED A FLUTTERING PERIODIC IDLE. THEY TOOK A LOOK $200.00 LATER TOLD ME I HAD MISFIRE IN #2 AND #5 AND NEEDED NEW HEAD. YOU CAN IMAGINE MY COMMENTS AND HE SAID IT IS COMMON HE JUST DID ONE LAST WEEK ON THE SAME YEAR AND TYPE H3! WELL I WAS IN TOUCH WITH GM - THE CAR IS OUT OF WARRANTY BUT LOW MILEAGE. THEY DID COVER A PORTION AND I WAS RESPONSIBLE FOR THE REST. WELL I PICK UP WEEK LATER. WAS TOLD IT WAS TEST DRIVEN AND RUNS GREAT. I TOLD THEM IT RAN GREAT BEFORE JUST THE FLUTTERING IDLE WHEN I STOPPED AT A LIGHT. THEY SAID YOU ARE ALL SET.. MANY BAD WORDS ESCAPED MY MOUTH WHEN I DROVE HOME AND IT WAS NOT FIXED. THE VEHICLE STILL DROVE THE SAME WAY IT DID BEFORE AND THE FLUTTER WAS STILL THERE,. SO NOW I HAVE TO BRING IT BACK AGAIN AND I MADE THE TECH GET IN THE VEHICLE SO HE KNEW WHAT I WAS TALKING ABOUT AND HE SAID WELL IT WAS BROUGHT IN FOR A MISFIRE. UHHH NO IT WAS NOT. WHY HAS GM NOT DONE ANY TYPE OF RECALL ON THIS IF IT IS KNOWN PROBLEM. FEEL LIKE THEY DON'T CARE SINCE THE VEHICLE IS NOT MADE ANYMORE WHAT DOES IT MATTER TO THEM. I COULD CONTINUE BUT AM LIMITED TO CHARACTERS. *TR

THE CHECK ENGINE LIGHT WENT ON AND OFF. THE VEHICLE WAS TAKEN TO A MECHANIC WHO DIAGNOSTIC AS CYLINDER #1 MISFIRE. COMPRESSION TEST FAILED DUE TO CYLINDER LEAKAGE. THE MAIN PROBLEM WAS TO AT THE TIME OF MANUFACTURING THE ENGINE SOFT METALS WERE USED WITH THE HEADS. I WAS TOLD I NEED TO REPLACE CYLINDER HEAD AND RELATED PARTS. CONTACTED GM HUMMER DIVISION INFORMED THEM OF MY PROBLEM WITH MY 3.5L, 5 CYLINDER ENGINE AND ASK THEM FOR ASSISTANCE SINCE THEY DID A SPECIAL EXTENDED WARRANTY FOR THE 2006 COLORADO AND CANYONS WITH THE SAME ENGINE PROBLEMS. THEY REFUSED TO HELP. *TR
