2005 Chevrolet Colorado Powertrain & Transmission Problems

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE CONTACT STATED WHILE DRIVING 40 MPH, THE VEHICLE HESITATED WHENEVER THE ACCELERATOR PEDAL WAS DEPRESSED. THE CONTACT STATED NO WARNING LIGHT WAS ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED WITH THE CHASSIS NEEDING TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER HAD BEEN INFORMED OF THE FAILURE AND REFERRED THE CONTACT TO A LOCAL DEALER. THE FAILURE MILEAGE WAS APPROXIMATELY 169,000.

THE INITIAL CONDITION THAT CAUSED CONCERN: HARD SHIFTING. TO MOVE THE SHIFTER BETWEEN ANY TWO POSITIONS REQUIRED HIGHER THAN NORMAL FORCE. THIS CONDITION ALLEVIATED INSTANTLY AFTER APPROXIMATELY ONE MONTH. THE FORCE REQUIRED TO MOVE THE SHIFTER BECAME NORMAL AGAIN. NO SOUNDS OR OTHER UNUSUAL THINGS WERE OBSERVED. THE ONLY DIFFERENCES FROM BEFORE THE CONDITION UNTIL THE CURRENT CONDITION IS THE TRANSMISSION WILL NOT GO INTO PARK, AND WILL ONLY START IN NEUTRAL. CURRENT CONDITION: THE TRUCK WILL NOT SHIFT INTO PARK. WHEN ATTEMPTING TO PUT THE VEHICLE INTO PARK, THE SHIFTER WILL MOVE ENOUGH TO ALLOW REMOVAL OF THE KEY, HOWEVER, THE TRANSMISSION WILL NOT ENGAGE PARK. BECAUSE OF THIS, THE VEHICLE IS ALWAYS FREE TO ROLL. THE ONLY WAY TO KEEP THE VEHICLE FROM MOVING WHILE ATTEMPTING TO PARK IS TO USE THE EMERGENCY BRAKE. THIS VEHICLE IS CURRENTLY BOTH HIGHLY INCONVENIENT TO DRIVE AND HIGHLY UNSAFE. ITEMS: - I HAVE FOUND BLOGS REFERENCING THIS ISSUE BACK TO 2004. I KNOW THIS EXPERIENCE IS NOT UNIQUE TO THIS VEHICLE. - I HAVE FOUND AN ARTICLE THAT SAYS A RECALL WAS ISSUED IN 2011 FOR EXACTLY THIS ISSUE: HTTP://TRUCKS.ABOUT.COM/OD/CARSAFETY/A/GM-RECALLING-COLORADO-AND-CANYON-TRUCKS.HTM BUT I CANNOT FIND ANY DOCUMENTATION FOR THIS ITEM ON YOUR WEBSITE. PLEASE PROVIDE FEEDBACK ON WHAT I AM MISSING. - THIS SERIOUS SAFETY ISSUE APPEARS CLEARLY TO BE A MANUFACTURERS DEFECT. CAN YOU FACILITATE DISCUSSION WITH THE OEM TO FIX THIS ISSUE PROMPTLY AT THE MANUFACTURERS COST.

TWO TIMES THE FRONT DIFFERENTIAL LOCKED INTO 4X4 BY ITSELF. THE TRUCK APPEARED TO SLIP INTO NEUTRAL AND ENGAGE INTO 4X4. THE 2 H LIGHT WAS ON, NOT 4 HI. I STOPPED, PUSHED 4HI, HEARD ACTUATOR ENGAGE, PUSHED 2HI AND 4HI DISENGAGED. THIS IS A SERIOUS SHOCK TO THE WHOLE FRONT RUNNING GEAR, UNIVERSAL S, RING AND PINION, AND TRANSMISSION. *TR

WHILE DRIVING AT ANY SPEED OR SITTING IDLE REDUCE POWER LIGHT COMES ON AND VEHICLE SLOWS DOWN. THIS IS VERY DANGEROUS AND FRUSTRATING. I'VE BEEN TO THREE DEALERS,AND THE DEALER IS THERE TO DEAL IN OTHER WORDS MAKE MONEY EVEN IF THEY DON'T FIX THE PROBLEMS. NOT TO MENTION TRYING THERE BEST TO GET YOU TO TRADE YOUR PROBLEM CAR IN AND BUY A NEW CAR. *TR

THE CAM ACTUATOR FIRST FAILED AT 57,000 MILES IN 2009. IT NOW HAS FAILED AGAIN AT 94,000 MILES IN MARCH 2013, THE COST TO REPAIR THIS IS APPROX $900.00 EACH TIME. I CAN GET MILAGE FROM MY TIRES AT A LOWER COST. THIS IS AN ITEM THAT SHOULD NOT A NORMAL MAINTENANCE ITEM. THIS TRUCK HAS BEEN A LEMON FROM DAY ONE. *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. WHILE DRIVING APPROXIMATELY 40 MPH, THE CONTACT NOTICED SMOKE EMITTING FROM THE REAR END OF THE VEHICLE. THE VEHICLE WAS TOWED TO THE CONTACT'S HOME. THE CONTACT INSPECTED THE VEHICLE AND NOTICED THAT THE TRANSMISSION LINE HAD DETACHED FROM THE TRANSMISSION FITTING, CAUSING THE TRANSMISSION FLUID TO LEAK. THE CONTACT REPLACED THE FITTING AND A CLIP IN ORDER TO ATTACH THE TRANSMISSION LINE BACK TO THE TRANSMISSION. THE VEHICLE WAS REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 124,000.

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE CONTACT STATED THAT THE VEHICLE HESITATED WHILE ATTEMPTING TO REVERSE. SHE APPLIED EXTREME PRESSURE TO THE ACCELERATOR BEFORE THE VEHICLE WOULD ENGAGE. IN ADDITION, THE VEHICLE WOULD INDEPENDENTLY SWITCH TO LOW FOUR WHEEL DRIVE GEAR WHILE THE VEHICLE WAS IN MOTION AT VARIOUS SPEEDS. THIS WOULD CAUSE THE REAR DRIVER'S SIDE WHEEL TO FEEL AS IF IT WAS DRAGGING AND THE STEERING WHEEL WOULD BECOME EXTREMELY TIGHT. THE MANUFACTURER ADVISED THERE WERE NO SIMILAR COMPLAINTS TO THE CONTACT'S AND DID NOT PROVIDE ANY ASSISTANCE. THE DEALER WAS UNABLE TO DUPLICATE THE FAILURE. A DIAGNOSTIC TEST WAS PERFORMED BUT DID NOT GENERATE ANY FAILURE CODES. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE APPROXIMATELY 27,000.

2005 CHEVROLET COLORADO I4 ENGINE 5 SPEED MANUAL TRANSMISSION. CANNOT ENGAGE REVERSE 70% OF THE TIME. I UNDERSTAND OTHERS HAVE EXPERIENCED THE PROBLEM BUT CHEVROLET HAS A TSB (#611) SAYING CONDITION IS NORMAL. I BELIEVE THIS IS A SAFETY ISSUE IF REVERSE CANNOT BE ENGAGED. PROBLEM HAS NOT BEEN RESOLVED. *TR

FOUR WHEEL DRIVE WILL NOT ENGAGE. THE LIGHTS ON THE DASH JUST FLASH AND EVENTUALLY RETURN TO 2HI. NOTHING WORKS - SHIFTING TO NEUTRAL, SLOW ROLL, DEAD STOP. NOTHING. I CYCLE THE 4WD ONCE A WEEK. WORKED LAST WEEK AND NOT THIS WEEK. LAST TIME 4WD WAS ACTUALLY USED WAS IN JANUARY 2009.*TR

INPUT HOUSING SHAFT SPLINES IN TORQUE CONVERTER WAS WORN OUT AFTER 44,000 MILES, WAS REPLACED AND WAS WORN OUT AGAIN AT 79,000 MILES. AFTER 35,000 MILE, I BELIEVE THIS IS A MANUFACTURER DEFECT OR THEY ARE USING A METAL THAT SHOULD NOT BE USED FOR TENSION. *TR

TL*THE CONTACT OWNS A 2005 CHEVROLET COLORADO. WHILE DRIVING APPROXIMATELY 35 MPH, THE CONTACT SMELLED A STRONG BURNING ODOR AND HEARD A LOUD RATTLING NOISE. THE CHECK ENGINE LIGHT ILLUMINATED ON THE INSTRUMENT CONTROL PANEL. THE DEALER STATED THAT THE BOLTS THAT HOLD THE OIL LUBRICATION FOR THE 4 WHEEL DRIVE WERE TOO LARGE, WHICH CAUSED THE FLUID TO LEAK. AS A RESULT, THE FOUR WHEEL DRIVE NO LONGER WORKS. THE VEHICLE HAS NOT BEEN REPAIRED. THE CONTACT HAS COPIES OF ALL WRITTEN CORRESPONDENCE, OUTLINING THE CAUSE OF THE FAILURE. SHE ALSO NOTIFIED HER STATE ATTORNEY'S GENERAL OFFICE AND THE MANUFACTURER. THE FAILURE AND CURRENT MILEAGES WERE 57,000.

TL*- WHILE DRIVING THE 2005 CHEVROLET COLORADO AT 40 MPH THE PASSENGER, LOOKING FOR THE VENT, MUST HAVE ACCIDENTALLY PUSHED THE 4 WHEEL DRIVE BUTTON. THE SAME DAY, WHILE BACKING INTO DRIVEWAY, THE TIRES SQUEAKED. THE CONTACT WAS UNHAPPY WITH THE DESIGN OF THE VEHICLE . HE BELIEVES IT IS TOO EASY TO ENGAGE THE 4 WHEEL DRIVE FUNCTION INADVERTENTLY. THIS VEHICLE HAS PART TIME 4 WHEEL DRIVE.*AK UPDATED 2/22/2007 - *NM

PURCHASED NEW 2005 COLORADO LSCREW4X4 IN NOVEMBER 2005. I HAVE NOTICED LATELY THAT WHEN BACKING UP OR DRIVING FORWARD AT AN ANGLE OVER A CURB OR ON A SLIGHT GRADE HEARD A KNOCKING/POPPING SOUND FROM THE REAR AXLE. IF YOU TAKE THE SIDE OF THE BED AND FORCE IT SIDE TO SIDE YOU CAN HEAR THIS KNOCKING/POPPING SOUN SEVERLY. I CALLED COMMUNITY CHEROVELT IN BURBANK, AND WAS TOLD BY SERVICE DEPARTMENT THIS WAS NORMAL SOUND. IT DOES NOT MAKE SENSE THAT THIS SEVERE OF A SOUND IS NORMAL. I CALLED ANOTHER DEALER, AND WAS TOLD TO BRING IT IN TO CHECK IT. I HAVE YET TO DO THIS.*AK

DT*: THE CONTACT STATED WHILE DRIVING 65 MPH, THE VEHICLE SHIFTED FROM 2 WHEEL DRIVE TO 4 WHEEL DRIVE LOW ON ITS OWN. THE VEHICLE HAD AN AUTOMATIC TRANSMISSION AND DUE TO THE GEAR SHIFT, THE VEHICLE BROKE DOWN ON THREE SEPARATE OCCASIONS. THE SERVICE DEALER COULD NOT DUPLICATE THE PROBLEM. *AK UPDATED 01/19/07.*JB

DURING NORMAL DRIVING MY TRUCK WILL SHIFT INTO 4WD-HIGH. I CANNOT DETERMINE IF IT OCCURS AT HIGHWAY SPEEDS OR LOW SPEEDS (<30 MPH), I ONLY NOTICE IT WHEN I GO TO TURN. THE OCCURANCE IS INTERMITTEN SINCE I BOUGHT THE TRUCK NEW IN SEPTEMBER 2005. IT HAS ALMOST CAUSE ME TO HAVE A HEAD-ON COLLISION WITH AN ONCOMING CAR AND A BUILDING BECAUSE THE TURNING RADIUS IS AFFECTED WHEN IT SHIFTS INTO 4 WD. SINCE THE TRUCK HAS PUSH BUTTEN CONTROL TO CHANGE TO 4 WD, FOR SEVERAL MONTHS I THOUGHT I BUMPED OR PUSHED THE BUTTON BY ACCIDENT, BUT THAT IS NOT THE CASE. I HAVE BEEN TO THE DEALER 4 TIMES, THE 4WD CONTROL HEAD HAS BEEN CHANGED (FAULT INDICATED), TRANSFER CASE CONTROL MODULE HAS BEEN CHANGED (INTERNAL FAULT INDICATED), ALL ELECTICAL WIRE HARNESSES TO THE TRANSFER CASE MODULE-CONTROL HEAD WERE CHECKED FOR SHORTS. PROBLEM NOT IDENTIFIED OR SOLVED AND GM SERVICE TOLD DEALER TO QUIT TRYING DIFFERENT THINGS SINCE THE PROBLEM COULD NOT BE IDENTIFIED. THE VEHICIAL IS STILL UNDER NEW CAR WARRANTRY. IN ANOTHER DRIVE TRAIN ISSUE THAT MAY OR MAY NOT BE RELATED TO THE AUTOMATIC SHIFTING INTO 4WD IS A COMPLETE REBUILD OF THE AUTOMATIC TRANSMISSION AT 4200 MILES. THE TRANSMISSION HAD TO BE REBUILT BECAUSE NO NEW TRANSMISSION WAS AVAILABLE IN N. DAKOTA. I HAVE HAD NO OTHER PROBLEMS WITH THIS TRUCK. *NM

ON OR AROUND MARCH 21, I WAS DRIVING MY 05 COLORADO TO WORK. WHEN I ALMOST ARRIVED I NOTICED THAT MY TRUCK WAS DRIVING VERY FORCEFUL AND JUMPY. WHEN I GOT BACK INTO MY TRUCK, IT WAS HAVING TROUBLE STARTING, BUT EVENTUALLY DID. THAT NIGHT I WAS DRIVING HOME AND WHEN I GOT ABOUT 2 MILES FROM MY HOUSE A MESSAGE CAME UP ON MY DASHBOARD THAT SAID POWER FAILURE AND IT STALLED OUT. THE NEXT DAY, IT STARTED OK ENOUGH FOR ME TO TAKE IT TO A NEARBY CHEVY DEALERSHIP. THEY TOLD ME THAT IT WAS THE SOLENOID VALVE AND THE CAMSHAFT POSITION ACTUATOR WAS REPLACED. IT DROVE FINE UNTIL A FEW WEEKS LATER ON APRIL 11TH WHEN MY TRUCK WOULD NOT START AT ALL. I HAD TO BE TOWED TO THE SAME DEALERSHIP, WHERE THEY FOUND THAT THE IGNITION SWITCH NEEDED TO BE REPLACED. I WAS WITHOUT MY TRUCK FOR 4 DAYS. *NM

I HAVE HAD THE VEHICLE INTO THE DEALER 7 TIMES BECAUSE IT SUDDENLY AND ON ITS OWN SHIFTS INTO 4H FROM 2H. ONCE, THIS HAPPENED AT 45 MPH AND THE VEHICLE'S SUDDEN SHIFTING INTO 4 WHEEL DRIVE THREW ME ONTO A ROCKY SHOULDER. DEALER REPEATEDLY SAYS HE CANNOT DO ANYTHING ABOUT IT,BECAUSE CHEVROLET DOESN'T KNOW WHAT TO DO ABOUT IT. INCIDENTS ARE BECOMING MORE FREQUENT. COMPUTERS HAVE BEEN REPROGRAMMED, WHICH DOES NOT SOLVE THE PROBLEM. LATEST INCIDENT DELINEATED BELOW. *NM

MANUAL TRANSMISSION HAS GRINDING NOISE WHEN SHIFTING INTO 1ST, 2ND, OR 3RD GEARS. *JB

THERE ARE 2 MAJOR SAFETY PROBLEMS ASSOCIATED WITH MY MANUAL TRANSMISSION. 1. WHEN COLD, IT IS PRETTY MUCH IMPOSSIBLE TO DOWNSHIFT INTO 1ST OR 2ND GEAR UNLESS I COME TO ALMOST A COMPLETE STOP. WHAT THIS MEANS IS I CANNOT GET INTO THESE GEARS TO SPEED UP QUICKLY IF I NEED TO AVOID AN ACCIDENT. CHEVROLET SAID THIS IS NORMAL! 2. IT IS DIFFICULT TO SHIFT INTO REVERSE SOME TIMES. CHEVROLET EVEN HAS A BULLETIN, BUT THEY SAID THIS IS NORMAL AS WELL! WHAT IF I NEED TO GO IN REVERSE REAL QUICK TO AVOID AN ACCIDENT OR A TRAIN? *TR

2005 CHEVROLET COLORADO 4 WD SHIFTS INTO 4WD LOW ALL BY ITSELF. *JB
