2005 Chevrolet Colorado Engine

MOTOR COMPRESSION,

I HAVE A 2005 CHEVY COLORADO STANDARD CAB 2.8 LITER AFTER 3 YEARS I NOTICED ENGINE INTERNAL NOISE START IT UP NOW IT SOUNDS LIKE A DIESEL A LOT OF STUFF IS KNOCKING AROUND INSIDE THE MOTOR I HEARD IT WAS SOME TYPE OF RECALL ON THAT BUT I'M NOT SURE I DO REMEMBER I HAD PROBLEMS WITH THROTTLE BODY HAVE BEEN REPLACED TWICE AFTER THIS REPLACEMENT FROM A CERTIFIED TECHNICIAN THAT'S WHEN THE PROBLEM OF REDUCED POWER FAILURE EMITTING FROM MY DASH COULD NOT GO OVER 40 MILES AN HOUR CHECK ENGINE LIGHT WOULD COME ON SO I WAS TOLD TO DISCONNECT BATTERY FOR ABOUT AN HOUR TO LET COMPUTER REBOOT AND THE PROBLEM WOULD GO AWAY JUST FOR A LITTLE WHILE WHEN THE MOTOR IS COLD THERE'S NO NOISE IT SOUNDS LIKE IT'S NEW BUT WHEN IT HEATS UP THAT'S WHEN ALL THE NOISES BEGIN I ALWAYS CHANGE MY OIL OUT EVERY 3000 MILES OR 3 MONTHS I USED CASTLES 70,000 MI PLUS BECAUSE I HAVE 110000 MI ON THE VEHICLE I DON'T KNOW IF ANYONE WHO'S HAD THE SAME PROBLEM AS FAR AS THE KNOCKING IN THE MOTOR BUT I DO KNOW THAT PEOPLE HAVE HAD PROBLEMS WITH THEIR THROTTLE BODIES MALFUNCTIONING AND CAUSING THE TRUCK TO RUN ROUGH AND SLOW AND SLUGGISH NOW I DON'T DRIVE IT VERY FAR BECAUSE I'M AFRAID THAT POWER REDUCTION LIGHT WILL COME ON IN MY DASH THEREFORE I CAN'T GO OVER 40 MILES AN HOUR WHICH I'VE MENTIONED THIS BEFORE ALL I CAN SAY IS AFTER THIS WITH THE THROTTLE BODY MOTOR HAS BEEN GIVING ME PROBLEMS VEHICLE WAS IN MOTION

MULTI CYLINDER COMPRESSION FAILURE

IN FEBRUARY 2015 MY CHECK ENGINE LIGHT CAME ON. AFTER SEVERAL REPAIRS WITH MY LOCAL MECHANIC HE WAS UNABLE TO FIND THE PROBLEM. I WENT TO GREENWOOD CHEVROLET IN HUBBARD, OH, AND THEY RESET MY COMPUTER. HOWEVER, BEFORE I GOT OUT OF THE AUTO LOT, THE CHECK ENGINE LIGHT REAPPEARED. I RETURNED TO THE SERVICE DEPARTMENT AND THEY THEN DIAGNOSED A BAD CYLINDER HEAD AND VALVES. THE SERVICE MANAGER REPORTED THIS HAS BEEN A PROBLEM WITH THIS PARTICULAR ENGINE AND MY ONLINE RESEARCH REVEALED THAT CHEVROLET RECOGNIZED THIS PROBLEM AND EXTENDED THE WARRANTY COVERAGE TO 7 YEARS AND 100,000 MILES. MY VEHICLE ONLY HAD 87335 MILES, BUT HAD BEEN IN SERVICE FOR 9 YEARS, 7 MONTHS. I FELT CHEVROLET SHOULD HAVE COVERED MY REPAIRS UNDER THE 100,000 MILES EXTENSION EVEN THOUGH I WAS OVER THE 7 YEARS. MY REASONING IS THAT CHEVROLET WAS AWARE OF THIS PROBLEM WITH THIS PARTICULAR ENGINE AS EVIDENCED BY CHEVROLET'S SERVICE BULLETIN #07123A. I CONTACTED THE PRESIDENT AND CEO OF GENERAL MOTORS AND PROVIDED THEM WITH ALL MY SERVICE RECORDS TO OFFER PROOF OF MAINTENANCE DURING MY OWNERSHIP. I HEARD NOTHING FROM THEM. I AM FILING THIS COMPLAINT BECAUSE I FELT GM SHOULD HAVE COVERED THE REPAIRS BECAUSE OF THE MILEAGE OF MY VEHICLE AND THE CARE I HAD DONE TO IT. IT COST ME OVER $2000 TO HAVE THIS VEHICLE REPAIRED.

THERE ARE SEVERAL FORUM ONLINE EACH PRETTY MUCH EXPRESSING THE SAME PROBLEM. AT THE 100,000 MILE MARK THE CHECK ENGINE LIGHT COMES ONE INDICATING THE #2 COIL IS BAD. THIS DOESN'T SEEM TO BE THE PROBLEM NOR IS IT IN THE INJECTORS. IT SEEMS WITH THE ONLINE FORUMS THAT ARE OUT THERE INDICATES THERE WAS A PROBLEM WITH THE HEAD ON THE 2005 COLORADO BUT CHEVROLET OR GM IS NOT INVESTIGATING OR TALKING ABOUT IT. *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE VEHICLE FAILED TO ACCELERATE AND STALLED WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. IN ADDITION, THE CHECK ENGINE LIGHT ILLUMINATED. THE VEHICLE WAS ABLE TO RESTART. THE DEALER DIAGNOSED THAT THE INTAKE MANIFOLD VALVE NEEDED TO BE REPLACED. THE VEHICLE HAD NOT BEEN REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 67,000.

ENGINE IDLE SPEED. WHEN DECELERATING TO STOP, THE ENGINE IDLES SO LOW THAT IT QUITS AND HAS TO BE RESTARTED. *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE CONTACT STATED THE VEHICLE WAS LEAKING OIL. THE VEHICLE WAS TAKEN TO THE DEALER WHO REPLACED A VALVE COVER ROCKER AND GASKET HOSE. THE DEALER CONFIRMED THAT THERE WAS EXCESSIVE OIL CONSUMPTION IN THE ENGINE. THE MANUFACTURER WAS CONTACTED, BUT THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 45,000 AND THE CURRENT MILEAGE WAS 60,000.

MY SISTER HAS A 2005 CHEVY COLORADO SHE BOUGHT NEW. THE CAM SENSOR KEEPS GOING OUT ON IT. MY BROTHER-IN-LAW IS RECOVERING FROM STAGE 4 CANCER AND THIS IS THEIR ONLY VEHICLE AND IT NEEDS TO BE FIXED AND AT NO COST TO THEM. THE PART IS POORLY DESIGNED IN REGARDS TO THE CONDENSATION THAT BUILDS UP. SOME PEOPLE DON'T HAVE GARAGES OR CAR PORTS AND IF THE SENSOR GETS WET IT BURNS OUT. I WILL NEVER BUY A CHEVY PRODUCT, THEY DON'T STAND BEHIND THEIR VEHICLES. *TR

FAULTY CAM ACTUATOR SOLENOID CAUSES LOSS OF POWER AND ROUGH IDLING. COMMON TO 2005-2006 CHEVY COLORADO/GMC CANYONS. THIS FAULT ALSO RELEASES DEBRIS INTO THE ENGINE THAT CAUSES POTENTIAL FOR FURTHER DAMAGE. OCCURRED AT 70K MILES ON MY VEHICLE WITHOUT PRIOR WARNING AND ALL REGULARLY SCHEDULED MAINTENANCE HAS BEEN PERFORMED. REPLACEMENT OF THE SOLENOID AND AN OIL CHANGE IS NECESSARY TO CORRECT THE ISSUE (THAT GM IS AWARE OF SINCE THEY'VE REDESIGNED THE SOLENOID SINCE THIS EDITION). *TR

COLORADO, 5-CYLINDER ENGINE PROBLEMS, STALLING AND ROUGH IDLING. STALLS AND RUNS POORLY. WHY HAS DEALER NOT ISSUED RECALL FOR ALL OF THESE FOR CYLINDER HEAD WORK? DEALER WANTS ME TO PAY FOR IT. *TR

I OWN A 2005 CHEVY COLORADO. IT HAS ONLY 86,000 MILES AND THE HEAD AND INTAKE VALVES AND CYLINDERS NEED TO BE REPLACED. I DID SOME RESEARCH AND MANY PEOPLE ARE COMPLAINING OF THE SAME THING FROM 2004-2005 MODELS. THE TOTAL COST FOR ME TO FIX THIS IS 1,600. GM KNOWS THEY MESSED UP WITH THE 2004-2005 INLIVE 5 ENGINES, THAT WHY IN 2006 THEY HAD DIFFERENT INTAKE VALVES INSTALLED. MY DEALER SAID THAT GM TOLD THEM TO FIX THE VALVES AND SEALS AND SPRINGS, BUT THAT IS NOT HELPING THE STATUS. SO THEN THEY WERE TOLD TO REPLACE THE HEAD WHICH COST AROUND $800. COULD SOME ONE PLEASE HELP ME WITH THIS? I DON'T SEE HOW A COMPANY CAN NOTICED THEY DID SOMETHING WRONG BUT NOT HELP TO FIX THE PROBLEM. I HAVE ALSO HEARD SEVERAL STORIES THAT THE INTAKE MANIFOLD CRACKS ON SOME TRUCKS, WHO HAS EVER HEARD OF THAT? I ASKED 2 PEOPLE WHO HAVE WORKED ON CARS FOR OVER 30 YEARS, THEY HAVE NEVER HEARD OF THAT HAPPENING. PLEASE ADVISE........... *TR

2005 CHEVY COLORADO WITH AROUND 84,000 MILES (BLOWN ENGINE)!!! BROKEN PISTON CONNECTING ROD; PUTTING TWO HOLES ON EACH SIDE OF THE CYLINDER WITH THE PISTON ROD STICKING COMPLETELY THROUGH THE OPPOSITE SIDE OF THE CYLINDER. OIL AND SMOKE THAT CAME FROM THE VEHICLE COULD HAVE CAUSED A TERRIBLE ACCIDENT, ESPECIALLY IF THERE HAD BEEN A MOTORCYCLE BEHIND ME. REPLACED ENGINE MYSELF DUE TO GM DOING NOTHING. FILED A CASE WITH THEM AND IT WAS DENIED. *TR

HEATER FAN QUIT WORKING ON 1 2 AND 3. BUT SOMETIMES WOULD COME BACK ON, WHEN ON 1 2 OR 3. AND WHEN IT WAS ON YOU COULD SMELL PLASTIC BURNING. AND WHEN CHECKED THE INTO IT FOUND THE PLUG ON THE WIRING HARNESS THAT PLUGGED INTO THE RESISTER ON THE FAN WAS LOOSE AND CAUSING THE WIRES TO MELT. THIS LOOSE PLUG WAS LOOSE FROM THE FACTORY, NO WAY COULD HAVE GOT TOO SMALL OVER THE YEARS. NEW PLUG AND NEW RESISTER PLACED CONCERN IF FIRE RESULTS COULD CAUSE DEATH INJURIES, GARAGE FIRE OR HOUSE FIRE IF VEHICLE PLACED IN GARAGE AT NIGHT. *TR

AS MY 2005 COLORADO REACHED APPROXIMATELY 49,000 MILES I NOTICED THAT IT BECAME MORE DIFFICULT TO START AND DIDN'T RUN AS SMOOTHLY AS IT HAD PREVIOUSLY. A COUPLE OF WEEKS LATER, AFTER THE CHECK ENGINE LIGHT CAME ON I HAD THE TRUCK SERVICED, AND WAS TOLD THAT THE CYLINDER HEAD AND RELATED COMPONENTS NEEDED TO BE REPLACED AT A COST OF $3500 TO $4000. LIKE MANY OTHERS, I HAVE NOW LEARNED THAT THIS WAS A COMMON OCCURRENCE . AND EVEN WORSE, IT SEEMED THAT IT MAY BE A RECURRING PROBLEM. I WAS TOLD BY THE DEALER THAT ALTHOUGH GM HAS ISSUED A TECHNICAL SERVICE ADVISORY AND THEY WERE VERY AWARE OF THE PROBLEM CHEVROLET WILL NOT ISSUE A RECALL OR TAKE CARE OF THE PROBLEM WHEN IT OCCURRED. *AK

I HAVE HAD PROBLEMS WITH MY TRUCK AND THE CHECK ENGINE LIGHT, WHEN SERVICED I FOUND THAT IT WAS THE CYLINDER HEAD THAT NEEDED TO BE REPLACED. THE SERVICE DEPARTMENT AT THE CHEVY DEALER SAID THAT IT IS A KNOWN AND COMMON OCCURRENCE IN THE 2005 5 CYLINDER COLORADO. AFTER DOING RESEARCH I FOUND THAT MANY OTHERS HAD THE SAME PROBLEM, SOME SAYING THAT EVER 15000 MILES THEY HAVE HAD TO REPLACE THE CYLINDER HEAD, AND ONE GUY EXPLAINED CHANGING IT FOR THE 3RD TIME WITHIN THE 2 YEARS THAT HE HAS OWNED HIS COLORADO. *JB

I WAS DRIVING AND MY TRUCK WAS SHAKING AND SPITTING AND SPUTTERING AND WASN'T WANTING TO RUN RIGHT. WHEN IT WAS IDLING IT WAS CHOPPY THE CHECK ENGINE LIGHT CAME ON IT WAS ALMOST LIKE THE TRUCK WAS POSSESSED. I GOT TO MY FRIEND'S HOUSE AND I CHECKED TO MAKE SURE THAT IT WAS GETTING ENOUGH VOLTAGE FROM THE BATTERY LIKE MAYBE THE CABLES WERE LOOSE BUT THEY WEREN'T. I CRANKED THE TRUCK BACK UP AND IT WASN'T SHAKING AND GOING CRAZY BUT WHEN IT IDEALS IT DOESN'T SOUND RIGHT/ISN'T LIKE IT SHOULD BE. *JB

THE SALES PERSON PROMISSED ME A LOT OF THINGS AND NOW THEY DO NOT WANT TO FIX THE TRUCK . I AM HAVING A LOT OF ENGINE PROBLEMS WITH THIS TRUCK AND I WOULD LIKE TO GIVE IT BACK TO THE DEALER.*AK

CHECK ENGINE LIGHT CAME ON IN 90 DAY OLD VEHICLE - CHEVROLET WAS FULLY AWARE OF THE PROBLEM WHEN I TOOK IT TO THE DEALER AND FIXED IT. I HAD TO PULL OVER ON THE EXPRESSWAY TO READ MY OWNERS MANUAL TO DETERMINE IF I COULD PROCEED - VERY DANGEROUS. CHEVROLET SHOULD BE MADE TO FIX ALL COLORADOS BEFORE SOMEONE GETS KILLED ON THE HIGHWAY.

ATTEMPTED O TO START VEHICLE AND IT WILL NOT START. TOOK VEHICLE TO DEALER 5 TIMES, AND COULD NOT FIND ANYTHING WRONG WITH IT. WAITED ABOUT 10-15 MINUTES THEN WILL START. NO MATTER WHAT THE TEMPERATURE WAS OUTSIDE HAD THE SAME PROBLEM. *AK

I PURCHASED A NEW 2005 CHEVY COLORADO IN NOVEMBER, 2004. I DID MY FIRST OIL CHANGE AT ABOUT 500 MILES. MY SECOND OIL CHANGE WAS DONE ABOUT 2,000 MILES. AT THAT TIME I NOTICED OIL DRIPPING FROM THE REAR PORTION OF THE ENGINE. I PULLED OFF A RUBBER COVER ON THE BOTTOM OF THE TRANSMISSION AND NOTICED DRIPS COMING FROM THE REAR MAIN SEAL AREA. I CALLED THE DEAL AND THEY TOLD ME TO BRING IT IN, WHICH I DID. A COUPLE OF DAYS LATER I RECEIVED CALL TELLING ME THE REAR MAIN SEAL WAS LEAKING AND THEY WOULD NEED TO REPLACE IT, SAYING IT WAS A FACTORY ASSEMBLY ERROR. ABOUT 2 WEEKS LATER I CHANGED THE OIL AGAIN AT ABOUT 3,500 MILES AND NOTICED OIL LEAKING AGAIN FROM THE SAME AREA. I CALLED THE DEALER AGAIN AND WAS TOLD DOUBTFUL IT IS THE SEAL AGAIN, BUT TO BRING IT IN. AGAIN I GOT A CALL SAYING THE SEAL WAS IN FACT LEAKING AGAIN AND THEY WOULD AGAIN NEED TO REPLACE IT. NOW A FEW WEEKS LATER, I WENT TO CHANGE THE OIL AT ABOUT 4,800 MILES ON IT ( I DO CHANGE MY OIL FREQUENTLY) AND SURE ENOUGH, THERE WAS OIL DRIPPING FROM THE SAME AREA. THIS TIME I CALLED THE DEALER AND THEY SAID THEY NEED TO CONTACT CHEVY TECHNICAL SUPPORT FOR POSSIBLE ANSWERSS. I STILL HAVE AN OIL LEAK AT THE REAR MAIN SEAL... *NM
