THE OIL HAS BEEN CHANGED BUT I WILL DRIVE IT 10 TO 15 MILES AND STOP. THE OIL LIGHT AND THE DINGER COME ON. I RESET THE BUTTON AND THEN COME TO THE NEXT STOP AND THE LIGHT COMES ON AND THE DINGER GOES OFF. THE ONLY WAY IT STOPS IS SHUTTING OFF VEHICLE AND LET IT SET OVERNIGHT. I CHECK THE OIL WHEN IT DOES THIS AND THE DIP STICK IS FINE. IS THIS AN OIL SENSOR PROBLEM AND IS THIS UNDER WARRANTY OR A RECALL? *TR

ENGINE LIGHT CAME ON DURING EMISSION TESTING, WHICH CAUSED THE VEHICLE TO FAIL. JUST HAD THE THERMOSTAT AND EVAPORATOR VALVE REPLACED THE WEEK BEFORE. THE EMISSIONS DEPARTMENT STATED THAT IT WAS A CODE P0300, MISFIRE IN CYLINDER 1. I TOOK THE VEHICLE FOR DIAGNOSTICS AND AFTER A COIL TEST AND COMPRESSION TEST (FAILED), THEY STATED THAT IS WAS A CYLINDER VALVE LEAKAGE. THEY ALSO STATED THAT THERE WAS A BULLETIN OUT ON 2006 H3 FOR THIS ISSUE. WHEN I CONTACTED GM CUSTOMER SERVICE, I WAS TOLD THAT THE VEHICLE'S VIN WAS NOT A PART OF THIS BULLETIN AND THAT THE MILEAGE WAS PAST THE WARRANTY. THE ONLY THING THEY COULD SUGGEST TO ME IS TO TAKE IT TO A GM CERTIFIED REPAIR FACILITY AND I WOULD HAVE TO PAY FOR THE COMPLETE REPAIR MYSELF. *TR

THE CHECK ENGINE LIGHT GOES OFF AND ON INTERMITTENTLY. THE VEHICLE WAS TAKEN TO A MECHANIC WHO PERFORMED A DIAGNOSTIC THAT LOCATED THE FAILURE AT THE ENGINE HEAD CYLINDER. 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....

DEFECTIVE CYLINDER HEAD FROM GMC - THEY KNOW ABOUT THIS PROBLEM BUT WON'T ASSIST WITH COST TO REPAIR, MY H3 AT 50,000 MILES NOW HAS CRACKED CYLINDER HEAD FOR NO APPARENT REASON AND OF COURSE SINCE MY WARRANTY IS NO LONGER IN EFFECT I HAVE NO RECOURSE. IS THERE NOTHING THAT CAN BE DONE ABOUT THIS? *JS

I OWN A HUMMER H3 THE OTHER DAY THE AIRCONDITION STOP WORKING I LOOK AT THE HEATER BLOWER THE LINKS TO THE AIR CONDITIONER THE WIRES AND RESISTOR WERE FRAYED AND EXTREME HOT.

I RECENTLY PURCHASED A 2006 H3. FROM THE DAY I BOUGHT THE CAR I HAVE NOTICED A WEIRD IDLE WHEN THE VEHICLE IS WARMING UP. UNTIL RECENTLY I THOUGHT IT WAS THE WAY THE VEHICLE RAN NORMALLY. I DECIDED TO HAVE THE VEHICLE INSPECTED BY A MECHANIC. AFTER BEING INSPECTED THE MECHANIC NOTICED THE VEHICLE'S VALVES WERE NOT SEEDED RIGHT FROM THE FACTORY, WHICH HAS CAUSED THE MISFIRE, WHICH CAUSES THE WEIRD IDLE. I NOW AM IN THE PROCESS OF CONTACTING HUMMER TO SEE IF THERE IS A SOLUTION TO THE PROBLEM. THE VEHICLE HAS ONLY 61870 MILES ON IT AND I DON'T FEEL THIS SHOULD HAVE HAPPENED THIS SOON IN THE VEHICLES LIFE. SERVICE BULLETINS HAVE BEEN WARRANTED AND I WOULD LIKE TO FIND A REASONABLE SOLUTION TO THE PROBLEM. *TR

I HAVE A 2006 HUMMER H3 WITH A LITTLE OVER 15,000 MILES ON IT. THERE IS AN ISSUE OF "BAD CYLINDER HEADS" IN THESE 3.5L I5 ENGINES AND GM HAS NOT STEPPED UP TO THE PLATE FOR A RECALL. ANOTHER CYLINDER HEAD HAS BEEN ORDERED FOR MY VEHICLE AND WILL BE FIXED UNDER WARRANTY. WHAT HAPPENS WHEN MY WARRANTY RUNS OUT A YEAR FROM NOW. I AM NOT CRAZY ABOUT A DEALER TEARING DOWN MY ENGINE AT THIS POINT. IT HAS NOT BEEN BROKEN IN YET. I THINK THE WHOLE ENGINE SHOULD BE REPLACED. I FEEL GM KNEW OF THIS ALL ALONG AND BUILT THESE SUV'S ANYWAY WITH THE HOPES THAT THE MOTORS WILL LAST UNTIL THE WARRANTY HAS EXPIRED. *TR

PURCHASED A 2006 HUMMER H3 FROM THE SELLER IN THIS COMPLAINT. I PAID EXACTLY $23,250 ALL CASH FOR THIS VEHICLE. HE ACTUALLY DROVE THE VEHICLE TO NEW JERSEY FROM MASS. TO MY RESIDENCE. THE VEHICLE APPEARED TO BE IN EXCELLENT CONDITION, AS IT ONLY HAD 14K MILES WHEN I BOUGHT IT ONLY 3-MONTH'S AGO. ONE WOULD HARDLY THINK OF "HIDDEN" ISSUES AT THAT MILEAGE. IN ANY EVENT, I HAVE HAD REPAIRS TO THE REAR AND FRONT DIFFERENTIAL, AS IT HAD A LEAK AND THE FRONT END WAS OUT OF ALIGNMENT. THE MOST DISTURBING THING WAS THIS SELLER LIED TO ME AND MISREPRESENTED THE "TRUE" OR ACTUAL CONDITION OF THE VEHICLE. UNFORTUNATELY WHICH WOULD SURFACE AFTER HE LEFT WITH MY $23,250 IN CASH! I WOULD E-MAIL THE SELLER AND TOLD HIM HE MISREPRESENTED HIMSELF AND THE CONDITION OF THE VEHICLE AND HOW HE APPARENTLY ABUSED IT. MORE IMPORTANTLY, I DISCOVERED "EXCESSIVE"...

A ROUGH IDLE, CHUGGING / RUNNING CONCERN MAY BE ENCOUNTERED WITH A P0014 DTC. POSSIBLE CLOGGED FUEL INJECTORS. *TR

DT*: THE CONTACT STATED WHILE DRIVING 40 MPH ON CITY STREETS, THE VEHICLE RAN AND IDLED ROUGH. THE VEHICLE WAS EVENTUALLY DRIVEN TO THE DEALER WHO DETERMINED THE CYLINDER HEAD AND VALVES NEEDED TO BE REPLACED.

VEHICLE HAD AN ENGINE MISS FIRE THAT REQUIRED REPLACEMENT OF THE HEAD. MISS. RETURNED SHORTLY AFTER REPAIRS. DEALER SAID THERE WAS NO MISS. VEHICLE FILLED UP WITH WATER DURING A RAINSTORM. ALL INTERIOR HAD TO BE REMOVED AND DRIED OUT. ELECTRICAL PROBLEMS OCCURRED THAT REQUIRED FOUR BATTERIES OVER 12 MONTHS. DEALER STATED IT WAS MY PROBLEM, BECAUSE I HAD A SMALL INVERTER FOR COMPUTER. SOLD THE VEHICLE TO THE HUMMER DEALER AT A LOSS OF $15,000. HUMMER REFUSED ANY ASSISTANCE AFTER FIRST STATING THEY WOULD. *JB

DT*: THE CONTACT STATED THE ENGINE WAS MISFIRING CAUSING THE VEHICLE TO LOSE POWER WHILE DRIVING AT ANY SPEED. AFTER LOSING POWER, THE ENGINE RAN ROUGH AT THE DECELERATED SPEED. THE VEHICLE WAS TAKEN TO THE DEALERSHIP FOUR TIMES FOR THIS ISSUE. THE FIRST TIME THE DEALERSHIP CORRECTED CIRCUIT #239. THE SECOND TIME THERE WAS A LOSE TERMINAL. THE THIRD TIME THE #1 CYLINDER COIL WAS REPLACED AND THE FOURTH TIME THERE WAS A LOSE WIRE. THE VEHICLE IS RUNNING ON ONLY FOUR CYLINDERS. THE PROBLEM RECURRED AGAIN SHORTLY AFTER PICKING THE VEHICLE UP FROM THE DEALERSHIP.
