2005 Chevrolet Colorado SERVICE BRAKES, HYDRAULIC

I HAVE HAD NUMEROUS BRAKING PROBLEMS SINE THE THIRD YEAR OF OWNERSHIP. ABS LIGHT AND STOPPING PROBLEMS TO MANY TO MENTION! WAS TOLD BY DEALERSHIP AFTER $500.00 THAT CALIPERS WERE FROZEN FROM RUST! ALSO I HAVE BEEN GETTING ABS FAILURES ALSO. PLEASE HAVE GM MAKE THIS DANGEROUS SITUATION RIGHT. DOES SOMEONE NEED TO DIE BEFORE ACTION IS TAKEN? *TR

PROBLEM WITH MY CHEVY COLORADO. THERE IS A GRINDING SOUND EVERY TIME I BRAKE. IT EVEN DOES IT WHEN I GO FIVE MILES AN HOUR. IT DOES IT EVERY TIME THAT I TAKE A TURN IN THE STREETS EVEN IF I DO NOT USE THE BRAKES. THIS FAULT IN THE ABS SYSTEM WORRIES ME A LOT, BECAUSE I THINK IT'S A SERIOUS SAFETY ISSUE. *TR

ABS WARNING LIGHT WILL COME ON IN DRY WEATHER AND ABS WILL ENGAGE DIMINISHING BRAKING. THIS IS A KNOWN PROBLEM WITH CHEVROLET AND GMC 2004 - 2006 COLORADO AND CANYONS. GMC WILL REFUSE TO DO ANYTHING ABOUT IT. MY PERSONAL CASE IS THAT THEY TOLD ME THAT THEY CLOSED MY COMPLAINT UNTIL I SPEND $100. TO HAVE DIAGNOSTICS RUN FOR THE ERROR CODES. ALL ONE HAS TO DO IS GO TO EDMUNDS.COM AND LOOK AT THE HUNDREDS OF COMPLAINTS OUT THERE FOR THIS VERY PROBLEM, OR ANY OTHER VEHICLE FORUM FOR THAT MATTER. EVEN THE ERROR CODES ARE SHOWN. I FINALLY RELINQUISHED AND TOOK VEHICLE TO DEALER TO HAVE CODES READ. JUST LIKE THE FORUMS STATE THE ERROR CODES CAME BACK, C0035, LEFT FRONT SENSOR AND C00220, LEFT FRONT IN RELEASE TOO LONG. SENSOR AND NEW HUB IS ESTIMATED BY DEALER TO BE $762.00!!!!DEALER ALSO STATED GM IS AWARE OF THIS PROBLEM AND IT IS DUE TO POOR/FLAWED DESIGN. MY VEHICLE, EVEN THOUGH IT IS A 2005, IS IN SHOWROOM CONDITION. I SEVERELY BABY THIS TRUCK, EVEN TO THE POINT I PAINT THE UNDERCARRIAGE 3 - 4 TIME A YEAR. THIS IS A TRUE SAFETY HAZARD AND WILL CAUSE AN ACCIDENT DUE TO THE ABS ENGAGING UNEXPECTEDLY IN COMPLETELY DRY WEATHER AND THE BRAKE PEDAL BEGINS TO THUMP AND BRAKING IS SEVERELY REDUCED. *TR

I HAVE A Z71 CREW CAB 4X4 MODEL. THE ABS SYSTEM ENGAGES AT LOW SPEED ON DRY PAVEMENT WITH ZERO WHEEL SLIPPAGE. THIS IS USUALLY FOLLOWED BY THE ABS FAILURE LIGHT ILLUMINATING. THE SYSTEM RESETS WHEN THE VEHICLE IS TURNED OFF AND THE PROBLEM RECURS THE NEXT DAY IN AN ENDLESS CYCLE. THERE ARE NUMEROUS COMPLAINTS OF EXACTLY THE SAME PROBLEM ON SEVERAL WEB FORUMS. ABS BRAKES HAVE BEEN AROUND A LONG TIME AND OTHER MANUFACTURERS DO NOT HAVE THE RECURRING PROBLEMS THAT HAVE BEEN EXPERIENCED WITH THIS VEHICLE. THE TIME IS LONG PAST TO MAKE CHEVY DO A RECALL. *TR

ABS FAULT WARNING AND BRAKE LIGHT CAME ON. DEALER FIXED LEFT SIDE WHEEL ASSEMBLY AND SENSOR FOR $600 . LATER SAME THING HAPPENED. BRAKE LIGHT AND ABS FAULT WARNING STAY ON CONSTANTLY. BRAKES FAILED ONCE MOMENTARILY WITHOUT WARNING. THIS HAS HAPPENED ONCE, BUT COULD HAPPEN AGAIN AT ANYTIME. *TR

ABS FAULT LIGHT CONSTANTLY COMES ON/GOES OFF, AND IT IS APPARENT THAT THE SYSTEM IS FAILING. *TR

INTERMITTENT ABS FAILURE. CAUSES BRAKES TO APPLY UNEVENLY AND SOMETIMES WITHOUT WARNING. PROBLEM COMES AND GOES. *TR

THIS FAILURE STARTED WITHOUT CAUSE NOR WARNING. ABS PROBLEM. WHEN TRUCK STARTS AND IS DRIVEN ON DRY PAVEMENT, THE FIRST OR SECOND TIME THE BRAKE PEDAL IS PRESSED, THE ABS WILL ENGAGE, LIMITING MY BRAKING ABILITY. A MINUTE LATER "ABS FAULT" WILL APPEAR ON MY DASH. THE BRAKES WILL WORK FINE FOR THE REST OF MY DRIVE, EXCEPT NO ABS WILL BE AVAILABLE. THIS EVENT CAN HAPPEN SEVERAL TIMES DAILY, BUT USUALLY DURING THE FIRST MORNING START. NOTHING HAS BEEN DONE YET, STILL RESEARCHING. *TR

VEHICLE FOR NO APPARENT REASON WILL ENGAGE ABS WHERE BRAKES WILL PULSATE AND A TEMPORARY REDUCTION IN BRAKES WILL OCCUR. THIS WILL OCCUR WHEN THERE IS NO RAIN, STREETS ARE DRY AND SUNNY. IMMEDIATELY AFTER THIS OCCURRENCE THE ABS FAULT LIGHT WILL COME ON AND STAY ON UNTIL CAR IS STOPPED, TURNED OFF, AND RESTARTED. TOOK VEHICLE IN TO GM DEALERSHIP AND THEY SAID BRAKES WERE FINE. WHEN ABS ENGAGES, FOR NO APPARENT REASON, ONE WILL FEEL BRAKE PEDAL PULSATING AND A LOSS OF BRAKING WHICH CAUSES SOME IMMEDIATE ALARM FOR FEAR OF RUNNING INTO SOMEBODY OR POSSIBLY ALLOWING CAR TO GO TOO FAR INTO AN INTERSECTION WHEN TRYING TO STOP. MANY WEB SITES, FORUMS AND BLOGS, SUCH AS EDMONDS ARE LOADED WITH THESE COMPLAINTS ON 2004 - 2006 COLORADO'S, AS THIS IS NOT JUST A SINGLE OCCURRENCE IN A COUPLE OF VEHICLES. CONTACTED CHEVROLET BUT THEY ALWAYS POINT ME TO DEALERSHIP FOR THEM TO READ COMPUTER CODE FOR ERROR AT A COST OF $100 AND THEN WILL PRICE OUT THE COST FOR REPAIR. THIS IS A SAFETY HAZARD THAT GM IS VERY AWARE OF AND SELECTS NOT TO ADDRESS. *TR

THE DEALER ADVISED THE CONTACT THAT THE FAILURE WAS NOT COVERED UNDER WARRANTY AND OFFERED NO FURTHER ASSISTANCE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. NO REPAIRS WERE PERFORMED. THE CURRENT MILEAGE WAS 46,000. THE APPROXIMATE FAILURE MILEAGE WAS 30,000. THE VIN WAS UNAVAILABLE. UPDATED 10/07/2011 *LN *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE CONTACT STARTED THE VEHICLE AND THE ABS AND BRAKE WARNING INDICATORS WERE ILLUMINATED. THE CONTACT PROCEEDED TO DRIVE APPROXIMATELY 15 MPH WHEN THE BRAKE PEDAL WAS APPLIED WITH A DELAYED RESPONSE. THE BRAKE PEDAL ALSO EXTENDED TO THE FLOORBOARD. AFTER ENGAGING THE BRAKES NUMEROUS TIMES, THE VEHICLE CAME TO A STOP YET THE WARNING LIGHTS REMAINED ILLUMINATED UNTIL THE ENGINE WAS TURNED OFF. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO WAS UNABLE TO DIAGNOSE OR DUPLICATE THE FAILURE. THE VEHICLE WAS NOT REPAIRED AND THE FAILURE PERSISTED. THE FAILURE MILEAGE WAS 140,000.

ABS FAULT LIGHT STAYS ON. BRAKES DON'T WORK WELL. RESEARCHING THIS PROBLEM IT APPEARS THAT THERE ARE MANY 2005 CHEVROLET COLORADOS WITH SIMILAR ISSUES. I NO LONGER FEEL SAFE DRIVING MY TRUCK. GM SHOULD BE HELD ACCOUNTABLE FOR THIS. *TR

TL* THE CONTACT OWNS A 2005 CHEVROLET COLORADO. THE CONTACT STATED THAT WHILE HAVING THE OIL CHANGED BY AN AUTHORIZED DEALER, HE WAS INFORMED THAT ALL OF THE BRAKE FLUID NEEDED TO BE REPLACED. THE CONTACT WAS ALSO INFORMED THAT THE FAILURE WAS DUE TO BRAKE LINE CORROSION. THE FAILURE RECURRED ONCE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 62,000.

ABS ALARMS AT VARIOUS TIMES, WHICH DISABLES THE ABS SYSTEM. THERE IS A TECHNICAL SERVICE BULLETIN FOR THIS PROBLEM. SO FAR NO RECALL. THE LEFT FRONT WHEEL IS THE SOURCE OF THIS PROBLEM. IT APPEARS THAT CHEVY COLORADOS HAVE THIS CONDITION. *TR

MY 2005 COLORADO BRAKES WILL LOCK UP WHEN COLD. ESPECIALLY AFTER SOME MOISTURE. THIS IS VERY ANNOYING AND A SAFETY CONCERN SINCE, I HAVE GOOTEN CLOSE TO GETTIJNG REAR-ENDED WHEN THEY LOCK UP. *TR THIS PROBLEM SEEMS TO INVALIDATE MY ABS. THE TRUCK STARTED DOING IT AT ABOUT 30,000 MILES. I HAVE HAD THE BRAKES CHECKED, AND THEY ARE FINE. MY 1993 S-10 DID THE SAME EXACT THING. I EVENTUALLY GOT RID OF THE S-10, BUT NOW I HAVE THE VERY SAME PROBLEM WITH THIS COLORADO. AS FAR AS I AM CONCERNED THIS IS A VERY SERIOUS SAFETY ISSUE. HELP. HELOP. HELP. HELP.

I AM STATIONED OVERSEAS IN ENGLAND AND ROAD GET VERY SLIPPERY. THERE ARE DEALERSHIPS OVER HERE, BUT THEY DON'T MESS WITH AMERICAN TRUCKS. EVERYTIME I GET GOING, MY ABS KEEPS FAULTING OUT AND THERE IS NO ERROR CODE POPPING UP, BUT YET MY BRAKES KEEP GOING OUT AND I AM WONDERING WHAT'S GOING TO HAPPEN WHEN ALL THE BRAKES GO OUT AND I CAN'T STOP OR EVEN INJURE SOMEONE ELSE OR EVEN WORSE MY KIDS. *TR

2005 CHEVY COLORADO BRAKE LOCKS UP ON FRONT DRIVER SIDE LEADING TO HARD LEFT PULL ON VEHICLE TRAJECTORY AND SEVERE OVER HEATING AND SMOKE EMITTING FROM WHEEL WELL. I HAVE BEEN FORCED NUMEROUS TIMES TO PULL OVER TO ALLOW THE WHEEL TO COOL DOWN SO IT DOESN'T START A FIRE. USUALLY AFTER A COOL DOWN THE BRAKE SYSTEM RESPONDS FOR A WHILE. I HAVE HAD THE CHEVROLET DEALER REPAIR THE BRAKES AND WAS CHARGED FOR THE SERVICE. CHEVROLET DOESN'T CONSIDER THIS A WARRANTY ISSUE AND WILL DO NOTHING ABOUT IT EVEN THOUGH THERE HAVE BEEN MANY COMPLAINTS ABOUT THEIR BRAKE SYSTEMS ON THE COLORADO. I HAVE OWNED THE VEHICLE SINCE 2005 AND HAVE HAD CONTINUAL PROBLEMS WITH THE BRAKE SYSTEM AND THE ABS FAILURE WARNING LIGHTS AND AUDIBLE ALERTS. I RECENTLY HAD THE BRAKES INSPECTED AND CLEANED AND NEW PADS INSTALLED BY MONROE AND WAS INFORMED THAT THIS IS COMMON PROBLEM WITH THIS TYPE OF CHEVROLET ABS BRAKING SYSTEMS. *TR

I HAVE A 2005 COLORADO CREW CAB 4X4. ON SEVERAL DIFFERENT OCCASIONS THE BRAKE PEDAL HAD TO BE PUMPED TO STOP THE VEHICLE. ON WET ROADS IT IS LIKE DRIVING IN THE SNOW, IT WILL SLIDE IN WHAT EVER DIRECTION YOU ARE TRAVELING. I TOOK IT TO THE CHEVROLET DEALER AND THEY HAD TO REPLACE THE RIGHT HUB AND RIGHT SENSOR AND PUT ON NEW BRAKE PADS AND SHOES AND IT COST ME $1,181.80 AND I STILL HAVE NO IDEA WHAT CAUSED THE PROBLEM. WHEN THE BRAKES WORK THEY ARE VERY GOOD BUT WHEN THEY DON'T WORK IT PRESENTS A BIG PROBLEM FOR ME AND MY FAMILY. THE BRAKES HAVE ALWAYS SQUEAKED SINCE THE FIRST DAY I DROVE IT OFF THE DEALERS LOT AND THEY ARE STILL SQUEAKING TODAY. I WOULD TAKE IT BACK AND HAVE IT LOOKED AT AGAIN, BUT I CAN'T AFFORD IT !!!!!!! *TR
