The ABS light comes on and brakes go to the floor with minimum to no stopping power. When this happens the brakes wine. After this happens brakes return to normal but the ABS light comes on and stays on until the vehicle is cycled on/off. Once the computer sees that there is no issues with the ABS, the light goes off. This leaves you to believe that there was a "bug" in the electronics. Then without warning or a duration of time the problem comes back. And then this process starts all over again. Whats happens when I need the brakes to prevent a accident? after researching online this is a very common issue with this vehicle.

Fire fire fire an air conditioning resistor pack overheats and catches fire in the air conditioning plenum. This is the fan speed control resistor. I found mine to be melted down and the socket that it plugs into was also severely damaged. The only recommendation that the dealership offered was that I pay them to replace those components. I purchased those components and installed them myself. The same thing happened again. I determined that the ground used for several components in the cabin was insufficient and poorly connected. I replaced the factory installed ground with a heavier gauge wire and attached it to the tubular framing behind the stereo. This was a sufficient fix and I believe it is in GM's best interest to remedy this issue before a GM vehicle catches on fire in a carport or with children on board.

My 2005 Chevrolet Colorado will activate the ABS system during braking on warm dry pavement and the vehicle will not stop. During these events the ABS failure warning light was not illuminated. The brakes have failed at 4 mph and at 25 mph. Other times, the ABS failure warning light is illuminated and the brakes work fine. No consistency and will not repeat for mechanic.

On Saturday morning my truck would not start. I went to jump it, and with no keys in the ignition and not jumped yet the windshield wipers and interior light went on. This went on for over an hour. I replaced basically a new battery. The radio did not work and dash lights did not either. On Tuesday, April 17 after I picked up my son from school, the car started to make a loud scrunch noise and started to stall off and on. When I pulled into my drive way and shut off the engine I smelled something burning. I went to open the door and it would not open. I tried to open the windows and they would not go down. It was smelling really bad like something was on fire. About 25 seconds later, with no key in the ignition the interior lights went on. I put the key in the ignition but did not start it and tried the windows again and my drivers side went down and I got my son out through the window. It had to be towed to the dealership. They said it was my alternator which is getting fixed. Reading all the complaints I agree, why has this not been recalled. It's around 50K miles and the electrical goes. Luckily me and my son got out.

  • 60,000 miles
Blower motor fan speeds work intermittently. Fault was found in blower motor wiring harness where harness runs adjacent to glove box. Jostle the harness manually below the glove box and the blower motor speeds will go from off to only a few speeds to normal. This could definitely be a fire hazard.

The HVAC fan motor resistor & connector melted around one of the prong connections and wire. The resistor and wire harness are located just under and behind the glovebox on the passenger side. The result of the burning of these parts is that the blower speeds of 1-3 do not work but 4 still functions normally. This problem is more than an annoyance of the fan setting because the cause is melting wires and burning connections near the passenger's feet. Hopefully this connection can be recalled and redesigned before something serious happens. This appears to be a very common issue as evidence from this blog.

The wiring harness and the resistor pack for the HVAC burns and is melted and could possibly cause a fire. This is not just an electrical HVAC problem. It is a grounding problem, and causes all kinds of problems. The hazard lights, blinkers, and stop lights all stopped working on my truck. Most of the dash would go out intermitly. The aux plugs stopped working. I had replaced the battery, wiring harness and resistor pack twice. General Motors knows about this problem. It also affects the GMC canyon, and the Isuzu I-280 pick-up trucks. There should be a recall to correct this problem before someone is killed. No brake lights, no turn signals, fire/smoke in the cab, etc.

Faulty wiring harness that burns under the dashboard/glovebox on the passenger side (feet area). The harness controls the blower motor fan speeds 1,2,3 setting and has a resistor. The wiring harness/loop begins to melt and subsequently burn. My passenger brought it to my attention after it singed his shin; I unplugged the wiring loop prior to catching on fire. There are many online complaints at Chevy Colorado forums I.e. edmunds etc. Thank you.

The relay for the brake lights under the dash has failed 4 times on my Chevy Colorado. The last two failures occurred after the part was replaced with the supposedly redesigned part from the recall. When this happens the brake lights fail to operate and no indication is given to the driver.

  • 95,000 miles
The contact owns a 2005 Chevrolet Colorado. While driving various speeds, the contact noticed that the ABS and traction controls would illuminate without applying pressure to the brakes. The air conditioner switch would shut on and off while driving over a pot hole. The dealer was unable to duplicate the failure and advised the contact that there were no recalls. The contact did not inform the manufacturer nor was the vehicle repaired. A local mechanic inspected the vehicle and advised the contact that the electrical system needed to be repaired; however, it was non repairable. The current mileage was approximately 96,000 and the failure mileage was 95,000.

2005 Chevy Colorado HVAC fan/diode connector for blower motor. The blower motor has been malfunctioning for the past 12 months. The A/C fan speed finally has stopped working in all speeds except high(4). After searching on line I have found many consumers reporting the same issue. I have searched for listed recalls and have not found any and I feel this issues should be addressed because of the fire risk it poses.

Colorado 5-cyl

  • 45,142 miles
Several times over the past six months I have been left stranded temporarily by my Colorado not cranking. There seems to be no rhyme or reason to it. Some days it cranks fine. Others, it may take as long as 45 minutes and several attempts to get it to start. I have found many fellow Colorado owners have had this same issue and it seems to be caused by a faulty pass code switch/sensor in the ignition. I believe that this should be a recall issue due to numerous owners having the same problem.
