2008 Chevrolet Colorado Electrical Problems

All of your brake lights have stopped working and no longer turn on when you press the brake pedal, including the high-mounted brake light above the rear window. This is a known issue covered by recall 09V310000, but that recall is only available in certain states—not in New Jersey where your truck is registered. You're bringing it to a Chevy dealer for diagnosis, but you're concerned about the safety risk since other drivers won't see your brakes being applied. The fix will likely involve replacing the brake light switch or addressing the underlying electrical issue identified in the recall.

Your airbag deployed unexpectedly while the truck was parked and unoccupied, with keys only on the passenger seat. After that incident, you experienced a battery failure, followed by a complete loss of power to the dashboard even though other electrical systems still worked. The dealer replaced the body control module, but the problem persists—you suspect these electrical issues are all connected to the initial airbag deployment. The fix will likely involve diagnosing the electrical system connections between the airbag module and the body control module to identify what triggered the deployment and is causing the cascading electrical failures.

Your truck's electronic ignition system is taking about 10 minutes to start, which is preventing the engine from turning over normally. This appears to be a widespread issue affecting multiple trucks of the same model. The ignition system may need to be diagnosed and repaired or replaced to restore normal starting performance.

Your truck's PassLock security system is preventing the engine from starting, and this problem keeps coming back even after multiple repair attempts at different shops. You were left stranded again when it happened recently. The recurring issue suggests a deeper electrical problem that may require professional diagnosis to identify the root cause.

Your heater blower motor stopped working on the low, medium, and high fan settings. The blower motor resistor and its connector were burnt, which created a potential fire hazard.

Your truck's anti-theft system (Passlock) is activating on its own without you doing anything, which prevents the engine from starting. This has happened 4 times since you bought the vehicle 3 weeks ago, sometimes multiple times in a single day. The fix likely involves diagnosing the anti-theft system sensor or module and replacing it if it's malfunctioning.

A WELL KNOWN, RESEARCHED PROBLEM EXIST WITH MY MODEL TRUCK AND SEVERAL OTHER GM CARS WITH THE SECURITY PASSCODE WHICH CAUSES THE IGNITION TO FAIL THEREBY FORCING A WAIT TIME OF 10 MINUTES TO START THE CAR. THIS IS EXTREMELY DANGEROUS FOR ANYONE STUCK ON A RAILROAD CROSSING OR IF A FLOOD IS ABOUND OR SHOULD FOR EXAMPLE A RAGING LUNATIC HAPPENS TO BE IN CHASE WITH A WEAPON. SHOULD ANY OF THESE HAPPEN GM WOULD BE LOOKING AT MULTI MILLIONS PAYOUT TO VICTIMS. I CALLED AND EXPLAINED THIS TO THEM BUT TO MY AMAZEMENT, THERE IS NO RECALL. THIS IS KNOW FOR COLORADO, CANYON, HUMMER, IMPALA, HHR, COLBALT VEHICLES. THIS FAILURE TO START HAPPENS REPEATEDLY ALBEIT INTERMITTENTLY.

83000 MILES ON VEHICLE. AIR CONDITIONING SYSTEM ON. SMOKE AND PUNGENT ODOR STARTED EMANATING FROM PASSENGER SIDE WITH AIR BLOWER MOTOR ON, FOLLOWED BY BLOWER MOTOR STOP WORKING. INVESTIGATION SHOWED CONNECTOR ON BLOWER MOTOR WAS MELTED RESULTING IN A BAD CONNECTION TO THE MOTOR. REPLACED THE HARNESS AND AFTER 2000 MILES, AGAIN BLOWER MOTOR CONNECTOR MELTED.

THIS VEHICLE SEEMS TO HAVE A MIND OF ITS OWN. YOU GET IN THE VEHICLE TO GO SOMEWHERE AND IT WONT START. EVERYTHING COMES ON, LIGHTS, RADIO, A/C BUT IT WONT CRANK. LET IT SIT 10-20 MINUTES AND IT CRANKS RIGHT UP. AND IT DOESN'T DO IT ALL THE TIME. IT MAY HAPPEN 3 TIMES IN A WEEK THEN GO 2 MONTHS OR LONGER WITHOUT HAPPENING AGAIN. IT HAS CAUSED ME TO BE LATE FOR WORK, SITTING A THE GAS STATION MANY MANY TIMES!. I HAVE TRIED USING THE KEY FOB AND JUST USING THE KEY TO UNLOCK THE DOORS. IT DOESN'T MAKE A DIFFERENCE. PLEASE TELL ME HOW TO FIX THIS!

VEHICLE ACCELERATES ON ITS ON, VERY SCARY WHEN IN PARKING LOTS. STOPS WHILE CRUISE IS ON. ITS BEEN DOING THIS SINCE AUGUST 2016. WE HAVE TRIED CLEANING THROTTLE BODY. BUT SINCE IT DOESN'T DO IT WHILE THE CRUISE IS ON. WE HAVE TO ASSUME THEIR IS AN ELECTRICAL ISSUE.

TL* THE CONTACT OWNS A 2008 CHEVROLET COLORADO. WHILE DRIVING 65 MPH, THE CONTACT SMELLED A BURNING ODOR. THE CONTACT COASTED THE VEHICLE OVER TO THE SIDE OF THE ROAD AND NOTICED SMOKE APPEARING UNDER THE PASSENGER SIDE DASHBOARD. THE FAILURE RECURRED THREE TIMES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE HEATER FAN RELAY WAS BURNING AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 144,000.

IF YOU LEAVE IT SET FOR A DAY IT WILL NOT START NEW BATTERY AND ALTANATOR WAS TESTED IT WAS GOOD . AND AIRBAG LIGHT IS ON .

DRIVER SIDE BACK DOOR WIRING HARNESS BETWEEN DOOR AND FRAME. 3 WIRES ARE BROKEN INSIDE BOOT. THIS IS SECOND TIME THIS HAS HAPPENED. LASTED 3 YEARS. I HAVE PICTURES. PART NUMBER 15214393 JUNE 10 2012 AIR BAG LIGHT ON DASH. ONSTAR TOLD ME THAT SEAT BELT TENSIONER WAS NOT OPERATING, AND AIR BAG WILL NOT DEPLOY UNTIL IT IS CORRECTED. FOUND THAT DRIVER SIDE BACK DOOR THAT 2 WIRES WERE BROKEN IN THE HARNESS IN THE BETWEEN DOOR AND BODY IN BOOT. GM PART NUMBER 15214393. I HAVE PICTURES. THIS IS A PROBLEM AND STILL NO RECALL. NO AIR BAGS TILL FIXED.

THIS WAS THE FIRST TIME IT HAPPENED, AN IT IS STILL HAPPENING TO THIS DAY. WHILE YOU ARE DRIVING AT ANY SPEED THE VEHICLE GOES INTO REDUCED POWER MODE. THIS HAPPENS MOSTLY WHEN THE AIR IS COOL. AT IDLE THE RUM'S FLUCTUATE ABOUT 100 RPM ON DAYS IT HAPPENS MOST. THERE SHOULD BE A RECALL ON THE THROTTLE BODY'S SINCE YOU CAN'T JUST CHANGE THE TPS. *TR

TPMS FAILED AND FLASHES CONTINUALLY. CHEVROLET CAN'T FIX IT AND NEITHER CAN ANYONE ELSE. *TR

ELECTRICAL CONNECTOR FOR BLOWER MOTOR CAUGHT ON FIRE. *TR

THIS VEHICLE SEEMS TO HAVE A MIND OF ITS OWN. YOU GET IN THE VEHICLE TO GO SOMEWHERE AND IT WONT START. EVERYTHING COMES ON, LIGHTS, RADIO, A/C BUT IT WONT CRANK. LET IT SIT 10-20 MINUTES AND IT CRANKS RIGHT UP. AND IT DOESN'T DO IT ALL THE TIME. IT MAY HAPPEN 3 TIMES IN A WEEK THEN GO 2 MONTHS OR LONGER WITHOUT HAPPENING AGAIN. WE HAVE TAKEN IT TO 3 MECHANICS AND THEY CANT FIND ANYTHING WRONG. WE HAVE TAKEN IT TO THE DEALERSHIP AND THEY CANT FIND ANYTHING WRONG. THE SAME THING HAPPENS TO MY 2001 CHEVY SUBURBAN!

I SEE ON THESE POSTS THAT I AM NOT THE ONLY ONE THIS IS HAPPENING TO. PLEASE TELL ME HOW TO FIX THIS! *TR

I HAD THE STOP LAMPS FAIL ON MY 2008 CHEVROLET COLORADO, THERE WAS A RECALL ISSUED FOR THESE TRUCKS FROM 04-09 BUT MY TRUCK WAS NOT INCLUDED, I CALLED GM AND GOT NO WHERE WITH THEM AS FAR AS TAKING CARE OF THIS COMMON PROBLEM. THERE ARE OBVIOUSLY OTHER CHEVROLET COLORADO TRUCKS HAVING THE STOP LAMP PROBLEM THAT MAY NOT HAVE BEEN RECALLED AND SHOULD BE. *TR

SITTING STILL AFTER STARTING TRUCK, NOTICED "DOORS" LIGHT ON DASH. GOT OUT, CHECKED ALL PASSENGER DOORS AND GOT BACK IN DRIVERS SEAT AND CLOSED THE DOOR. DOOR AJAR CAUTION REMAINED LIT. RADIO WILL NOT TURN OFF WITH IGNITION OFF, KEY REMOVED AND DRIVERS DOOR OPENED. *TR

BATTERY KEEPS DYING GOT A NEW BATTERY AND IF I DON'T DRIVE IT ONE DAY AND GO OUT TO START IT ITS DEAD. AND ALSO THE AIRBAG LIGHT IS ON ,ROUGH IDLING. *TR

AIRBAG WARNING LIGHT CAME ON AND WONT SHUT OFF. TRIED A NEW FUSE BUT NOTHING WORKED. DON'T WANT TO SPEND 100 FOR TECH 2. *TR

TL* THE CONTACT OWNS A 2008 CHEVROLET COLORADO. THE CONTACT STATED THAT THE ENGINE FAILED TO OPERATE UPON STARTING THE IGNITION. THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALER FOR DIAGNOSIS. THE TECHNICIAN INFORMED THE CONTACT THAT THE MALFUNCTION WAS CONTRIBUTED TO THE FAULTY COMPUTERIZED SYSTEM CONTROL MODULE. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 26,700.

AC BLOWER MOTOR WORKS INTERMITTENTLY AND NOW DOES NOT WORK. OTHER PEOPLE ON THE WEB HAVE HAD SMALL FIRE MELTED WIRES. THIS HAS BEEN A PROBLEM WITH THE CHEVROLET COLORADOS. I HAD 2004 WITH THE SAME PROBLEM. SO AS YOU SEE IT IS A 4 YEAR OLD PROBLEM. WHEN ARE YOU FOLKS GOING TO ADDRESS IT WITH GM SINCE WE AS THE PEOPLE HAVE SOME MUCH INVESTED IN THEM. *TR

THERE IS AN ISSUE WITH THE DRIVER SIDE HEADLAMP, WHERE IT WILL NOT WORK UNDER NORMAL DRIVING CONDITIONS. I REPLACED THE HEADLAMPS TO HAVE THE SAME RESULT. ALSO REPLACED THE FUSE FOR THE LT HEADLAMP WITH SAME RESULT. THE LEFT HEADLAMP WILL WORK IN HIGH BEAM MODE BUT NOT IN NORMAL DRIVING CONDITIONS. I TRIED MANUALLY SWITCHING ON, SAME RESULT. *TR
