2008 Chevrolet Colorado

TL* THE CONTACT OWNS A 2008 CHEVROLET COLORADO. WHILE DRIVING 35 MPH, THE BRAKE PEDAL REQUIRED EXCESSIVE FORCE IN ORDER TO STOP THE VEHICLE. THE FAILURE OCCURRED ON NUMEROUS OCCASIONS. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO DIAGNOSED THAT THE REAR BRAKE DRUMS FAILED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 105,000.

MY VEHICLE ALMOST COMPLETELY LOST ALL OF IT'S BRAKES. UPON SHORT INSPECTION UNDER THE HOOD, I FOUND THE GROMMET THAT SEALS THE BRAKE SYSTEM CHECK VALVE TO THE POWER BOOSTER ALMOST COMPLETELY RIPPED INTO TWO PIECES. PRIOR TO THIS INCIDENT, NO MAINTENANCE OR ANY OTHER UNDER HOOD MAINTENANCE HAD BEEN PERFORMED ON THIS VEHICLE OTHER THAN REGULAR OIL CHANGES. THIS PART IS NOWHERE NEAR THE AREA REQUIRED ACCESS FOR AN OIL CHANGE SO THERE IS NO WAY THIS WAS CAUSED BY IMPROPER HANDLING OF THE PART.

THE BRAKES DRAG AND SQUEAL ALL OF THE TIME. THEY GRAB SOME OF THE TIME, AND HAVE TEMPORARILY LOCKED UP ON 6 OCCASIONS. BEING ABS; THEY DON'T ACTUALLY LOCK UP BUT DO GRAB HARD ENOUGH AND LONG ENOUGH TO MAKE THE TIRES "CHIRP". THE PROBLEMS ARE NOT NOTICEABLE AT HIGHWAY SPEED BUT THE LOWER THAN EXPECTED MPG AND HIGHER THAN EXPECTED VARIATION IN MPG MAKES ME THINK THEY OCCUR AT ALL SPEEDS. HAVING NO DOUBT THAT THE BRAKES ARE DEFECTIVE WORRIES ME. I'M ANXIOUS ABOUT WHEN THEY WILL FAIL AND AT WHAT SPEED. ON FOUR OF THE SIX "LOCK UP" OCCASIONS THE VEHICLE HAD SHIFTED ITSELF INTO HIGH RANGE 4WD. THAT MIGHT HAVE HAPPENED BUT WENT UNNOTICED THE OTHER TWO TIMES. EVERY TIME IT SHIFTED ITSELF INTO 4WD (AND TRIED TO LOCK THE BRAKES) WAS AFTER BACKING UP. WHEN THE VEHICLE IS SELF BRAKING; A TURN OF THE STEERING WHEEL MAKES THE VEHICLE BRAKE HARDER. A TURN OF MORE THAN 1/2 ROTATION RESULTS IN A "GRAB" AND A "CHIRP". IF STARTING FROM A STOP AND TURNING AT THE SAME TIME, THE REAR WHEELS MIGHT SPIN. I'VE BEEN DRIVING 4X4S FOR MANY YEARS. I KNOW THAT FRONT WHEELS "LURCH" DURING A TIGHT TURN. THAT IS NOT WHAT THIS VEHICLE IS DOING. IT WILL EXHIBIT THE SAME SYMPTOMS IN 2WD. I THINK IT'S AN ELECTRICAL PROBLEM. THIS COLORADO HAS BEEN TO THE SHOP FOR 8 ELECTRICAL FIXES ALREADY. THE NUMBER AND VARIETY OF ELECTRICAL PROBLEMS WITH THE COLORADO MODEL ARE STAGGERING. THEY SHOULD BE RECALLED AND MADE RELIABLE IN THE NAME OF SAFETY. UNFORTUNATELY, IT SEEMS LIKE A CERTAIN NUMBER OF INJURIES AND DEATHS MUST BE REACHED TO WARRANT A RECALL.

TL* THE CONTACT OWNS A 2008 CHEVROLET COLORADO. THE CONTACT STATED THERE WAS A SELF-ADJUSTING SPRING THAT WAS ACCUMULATING DIRT AND DEBRIS. AS A RESULT, THERE WAS A HOLE WORN IN THE BRAKE DRUM AND CAUSING THE BRAKES TO FAIL INTERMITTENTLY. THE DEALER ADVISED THAT THE FAILURE WAS AN ENVIRONMENTAL ISSUE. THE BRAKE DRUMS WERE REPLACED AT THE CONTACT'S EXPENSE BY THE DEALER. THE CONTACT BELIEVED THE FAILURE TO BE A DEFECT IN MANUFACTURING. THE FAILURE MILEAGE WAS 48,500 AND THE CURRENT MILEAGE WAS 50,000. UPDATED 11/19/2010 UPDATED 11/24/10. *JB

THE REAR BRAKE ADJUSTERS ARE FAULTY ON THE 2008 CHEVY COLORADOS. GM HAS ISSUED A TSB FOR THIS ISSUE #07-05-24-001B. THE SYMPTOMS ARE SQUEALING REAR BRAKES, HIGH REAR BRAKE WEAR, RUSTING ON DRUMS AND MORE. THE TSB IS ONLY GOOD UNTIL 36,000 MILES. MANY DEALERSHIPS WILL NOT PERFORM THE TSB REPAIR WHICH IS FREE. THEY WILL INSTEAD CHARGE THE CUSTOMER FOR A REAR BRAKE CLEAN AND ADJUST WHICH ONLY TEMPORARILY ELIMINATES THE SQUEAL UNTIL THE ADJUSTS FAIL TO ADJUST THE SHOES PROPERLY AGAIN. THIS ISSUE CAN CAUSE LOSS OF CONTROL UNDER BRAKING, ESPECIALLY ON WET ROADS. THIS IS AN ONGOING ISSUE WITH APPROXIMATELY 40 INSTANCES SEEN IN MY FLEET OF 92 COLORADOS-SO FAR . ISSUE OCCURS AT ANY MILEAGE. DOCUMENTED RANGES ARE FROM 10,000 TO END OF WARRANTY. VEHICLES HAVE SEVERAL OTHER ISSUES AS WELL. *TR

REAR BRAKE ISSUES NO PROBLEMS FOUND AT DEALER 2 TIMES I HAD TAKEN IT TO THEM. REAR BRAKE NOISE SCREECHING SQUEALING, LOCK UP WHEN MOISTURE IS PRESENT, AND IN AN EMERGENCY STOP THE PEDAL GETS REAL STIFF AND IS HARD TO STOP. I PUT IN A COMPLAINT TO CHEVROLET AND THEY SAID THERE IS NOTHING THEY CAN DO. I FEEL UNSAFE DRIVING THIS VEHICLE AFTER TWO CLOSE CALLS WITH EMERGENCY STOPPING. PLEASE HELP ME I DON'T KNOW WHAT TO DO I DON'T WANT TO GET INTO AN ACCIDENT. *TR

TL*THE CONTACT OWNS A 2008 CHEVROLET COLORADO. THE FRONT BRAKE PADS ARE EMITTING A FINE FIBER LIKE MATERIAL, WHICH IS GETTING ON THE FRONT WHEELS, THE FENDER, AND THE ROCKER PANEL. THE FIBER IS BLOWING IN THE AIR AND ENTERING INTO THE VENTILATION SYSTEM, WHICH THEN CAUSES THE BLACK FIBER TO ENTER THE PASSENGER CABIN. THE FIBER MATERIAL IS PRESENT THE MOST DURING CITY DRIVING. THE CONTACT MUST CLEAN THE WHEELS ONCE A WEEK. HE STATED THAT THERE WAS A TSB THAT MENTIONED THE FIBER WAS DAMAGING TO CHROME AND DYE CAST WHEELS. THE FAILURE MILEGE VIN, ENGINE SIZE, AND SPEED WERE UNKNOWN. THE CURRENT MILEAGE WAS 3,000.
