2006 Chevrolet Colorado Engine

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

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

WHILE DRIVING OUR 2006 COLORADO TRUCK, THE ENGINE QUIT RUNNING PLACING US IN DANGER FROM THE VEHICLES NEAR US. THIS HAS HAPPENED THREE TIMES. WE WERE ABLE TO NAVIGATE TO A SAFE ZONE. THE ENGINE STARTED AND WE CONTINUED OUR TRIP. WE ARE CONCERNED THAT WE MAY BE INJURED OR KILLED. WE ARE NOT DRIVING THE TRUCK UNTIL IT IS FIXED. *TR

ENGINE LOSES POWER OVER 55MPH AND MISFIRES ON CYLINDER ONE. ENGINE LIGHT COMES ON. DEALER REFUSES TO FIX AFTER LOOKING AT IT AND SAYING NOTHING HAS COMPLETELY FAILED YET. THEY ARE WAITING FOR ME TO BE STRANDED ON THE SIDE OF THE ROAD I GUESS. *TR

TL*THE CONTACT OWNS A 2006 CHEVROLET COLORADO. WHEN IDLING OR DRIVING 20 MPH, THE ENGINE RPM'S INCREASE. THE DEALER STATED THAT THE VEHICLE WAS DESIGNED THAT WAY FOR BETTER EMISSION. THE MANUFACTURER STATED THAT THE IDLING COULD NOT BE CORRECTED. THE CURRENT MILEAGE WAS 4,000 AND THE FAILURE MILEAGE WAS UNKNOWN.

POWER REDUCED WARNING AND ENGINE LIGHT COMES ON, CAN'T ACCELERATE ABOVE 50 MPH. DEALER IS CURRENTLY WORKING ON PROBLEM FOR THE FOURTH TIME. UNABLE TO CORRECTLY REPAIR OR FIND PROBLEM. VERY RUDE TREATMENT FROM DEALER. *TR UPDATED 09/18/07 *TR
