2006 Chevrolet Colorado

CHECK ENGINE LIGHT CAME ON INTERMITTENTLY. ENGINE HEATED UP AND TRANSMISSION WOULD NOT SHIFT INTO OVERDRIVE ON FREEWAY. TRANSMISSION SHIFTS HARD NOW AND THEN. CHECKED WEBSITE FOR ANY RECALLS ON ENGINE, TOOK TO DEALERSHIP, STILL UNDER WARRANTY. THEY KEEP THE TRUCK FOR 2 WEEKS, DID MACHINE WORK ON CYLINDER HEAD, COMPUTER SAID ALL CYLINDERS MIS-FIRING. PRINT OUT FROM CHEVROLET SAID 'HEAD REPLACEMENT', WHICH WAS NOT DONE. NOTIFIED GMC CUSTOMER SERVICE AND OPENED FILE. BACK TO DEALERSHIP SECOND TIME FOR DROP IN IDLE AND MISFIRE DURING DRIVING. COULD NOT FIND ANYTHING WRONG. DEALERSHIP SAID TO BRING BACK IF SAID CONDITION GETS WORSE. *TR

2006 CHEVY COLORADO PROBLEMS WITH AIRBAGS AND ENGINE STUTTERING. CONSUMER STATES THAT AIRBAGS SENSOR CAN NOT TELL WHEN HIS WIFE OR DAUGHTER ARE IN THE PASSENGER SEAT. HE STATES THAT THE ENGINE STUTTERS WHEN THE TEMPERATURE IS DECREASED. *KB THE CONSUMER STATED THE AIR BAG LIGHT DID NOT TURN ON WHEN THE SEAT WAS OCCUPIED AND SOMETIMES THE AIR BAG INDICATOR WOULD SUDDENLY SHOW THE PASSENGER AIR BAG WAS OFF. THE CONSUMER ALSO STATED ON ONE OCCASION, THE VEHICLE DID NOT WANT TO MOVE; IT WENT A VERY SLOW PACE NO MATTER HOW HARD THE ACCELERATOR WAS APPLIED. THE CHECK ENGINE LIGHT ILLUMINATED. THE DEALER STATED THEY FOUND A FUEL INJECTOR LEAKING. *JB

AFTER SEVERAL WEEKS OF CHECK ENGINE LIGHT GOING ON AND OFF I DECIDED TO HAVE THE TRUCK CHECKED OUT. AFTER DEALER RAN HISTORY, STATED THAT I NEEDED TO BRING TRUCK IN FOR A HEAD ISSUE. AFTER HAVING THE TRUCK FOR THREE DAYS, DEALER NOTIFIED ME THAT THEY PUT ENGINE BACK TOGETHER AND GOT IT FIRED BUT WAS LOSING COMPRESSION ON THE #1 CYLINDER. THEN THE ENGINE WAS MAKING VERY LOUD NOISES. AFTER TEARING ENGINE BACK DOWN, THEN NOTICED THE EXHAUST VALVE WAS STUCK IN THE DOWN POSITION, WHILE THE PISTON WAS GOING IN THE UP POSITION, IT BROKE THE PISTON IN PIECES AND BROKE THE VALVE. THE DEALER CONTACTED GM AS TO WHAT TO DO. GM IS SENDING A NEW ENGINE TO REPLACE THE BLOWN ENGINE. THERE IS ONLY 25,000 MILES ON THE TRUCK. *TR

VEHICLE EXPERIENCES ENGINE MISS FIRE CODE THAT CAUSES CHECK ENGINE LIGHT TO COME ON. SYMPTOMS STARTED AT 45,000 MILES. DEALER RESET COMPUTER FIRST TIME WITH NO REPAIRS NEEDED. COMPUTER SHOWED MULTIPLE MISS FIRES THE SECOND TIME. DEALER STATED THIS IS COMMON WITH HIGH MILEAGE COLORADOS DUE TO CARBON BUILD UP ON VALVES. DEALER DID CHECK TO ENSURE THERE WAS NOT A BAD COIL. SUGGESTED USING LUCAS FUEL TREATMENT. DID HELP ROUGH IDLE AND POWER. I WAS TOLD NEXT STEP WILL BE TO REPLACE THE HEAD. *TR

TRUCK MISFIRING ON ALL CYLINDERS SINCE AROUND JUNE 2007. CHECK ENGINE LIGHT ON SOME, OFF SOME. JUNE 19 DEALER SAID MISFIRING ON ALL CYLINDERS AND THEY WERE STUMPED. THEY FIRST GUESSED BAD GASOLINE THEN SAID COMPUTER NEEDED RECONFIGURING. STILL MISFIRING WHEN I LEFT SHOP. ON JULY 19 RETURNED TO DEALER. THEY SAID IT WAS A GM PROBLEM THAT GM WAS AWARE OF...POSSIBLY CRANKSHAFT SENSOR AND FOR ME TO COME BACK IN TWO WEEKS. ON AUG 18 I TOOK TRUCK BACK TO DEALER AFTER ENGINE QUIT IN A ROLLING TURN IN MIDDLE OF INTERSECTION. DEALER REPLACED FUEL PUMP AND SPARK PLUGS AND SAID THEY THOUGHT WATER WAS IN FUEL. DON'T GO BACK TO SAME GAS STATIONS THEY SAID. I HAVEN'T. TRUCK STILL WAS MISFIRING WHEN I LEFT. ON 9-26 I WENT BACK TO DEALER. TRUCK ENGINE SHUT OFF WHILE I WAS DOING 70MPH DOWN BUSY INTERSTATE. MADE IT TO SIDE OF ROAD, RESTARTED AND CONTINUED ON MY WAY. DEALER SAID IT WAS COMPUTER LOOSING COMMUNICATIONS INTERNALLY AND HAD CLOGGED FUEL INJECTORS. LEFT DEALER AND TRUCK STILL MISFIRING. DROVE IT FOR A DAY OR TWO AND WHEN FRIEND WHO WENT TO LUNCH WITH ME WONDERED IF WE WERE GOING TO MAKE IT BACK FROM LUNCH I DECIDED TO CALL DEALER. CALLED DEALER AND WAS TOLD IT WAS A SOFTWARE PROBLEM AND THAT GM IS WORKING ON IT. GROAN! TRUCK IS ALMOST OUT OF WARRANTY AND I AM WONDERING WHEN NEXT TIME ENGINE WILL QUIT RUNNING AND UNDER WHAT DRIVING CONDITIONS. THANKS....ROGER DOWDY *TR

DT*: THE CONTACT STATED WHILE DRIVING THE ENGINE REVS AT ALL SPEEDS. THE VEHICLE HAS BEEN TO THE DEALERSHIP TWICE FOR REPAIRS TO THE ENGINE. THEY REPLACED THE ACCELERATOR PEDAL AND THROTTLE BODY, BUT THE PROBLEM STILL EXISTS. ADDITIONALLY, THE PASSENGER SIDE AIRBAG LIGHT ILLUMINATED. ALTHOUGH THE DEALER WAS ALERTED NO APPOINTMENT FOR INSPECTION WAS MADE.
