Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

The blower motor resistor and the wiring is broken for the third time. This time there were burn marks on the wires which worries me about a possible fire in my dashboard. This occurs while the vehicle is on. This overheating/burning of the resistor and wires causes the blower motor to not blow air which in phoenix, AZ is a must due to severe hot weather.

A/C & heater controls not working. 1st time took pick-up in and was fixed under warranty at hudiburg cheverolet in Oklahoma city, ok. The same thing was happening again around 1 1/2 years later took back to hudiburgs again and they refused to fix it because it was out of warranty. A couple of weeks later it began to work for a little while then stopped working altogether.

The ac fan only works on high (4). The ac fan switch has a known defect in the resistor switch for the fan. This can cause the wiring to overheat and start a fire. GM has already recalled the Hummer H3 for the same problem. The recall should be extended to the 1st generation Chevy Colorado because it has the same fan switch resistor.

Driving down the road, all the sudden started to get a burn smell. Had to pull over and have the truck being towed to the shop. The problem is the harness connector to the A/C- heating blower was burning. Luckily I had discover the problem on time. This problem could be a dangerous fire. We need this problem to be addressed and fixed since all the owners of this vehicle have been having the same issue.

No speed required. The A/C & heater not working. It was fixed while under warranty and it worked for a series of months and then it began acting up again took the vehicle in and it had just gone out of warranty. It was obvious that the issue was exactly the same problem and they refused to complete their work. In the winter or during damp weather it's impossible to drive due to windshield fogging up. It presents a very unsafe condition.

The brake light switch installed by Chevrolet to replace the brake light switch that they had recalled, had also failed to work. It stopped working shortly after they had installed the new one, but I hadn't realized because I thought my brake lights just kept going out. I wasn't even aware that there was a recall on the brake light switch and that they had replaced it when I had taken it in for another recall issue. I even told my mechanic and he just replaced the brake lights. It wasn't until much later that I realized my lights were actually fine but that the brake light switch was not activating them. I reported this to GMC and they said that they would not fix it unless I paid for it out of pocket ($137 for a diagnostic test, $64 for the actual replacement).

Vehicle stalled while driving. Was able to restart but would only stay running for a few seconds. After several attempts it restarted and stayed running. Since that time the vehicle intermittently stalls immediately after starting and requires several attempts to restart and keep running. Security system light is on. Dealer said it could be the key, or the key switch, or the body control module (BCM), or all three. Research online indicates that numerous Chevy Colorado owners have the exact same problem and have been told similar things by dealers. In fact numerous owners of Chevy with the passlock security system have the same problem. It feels unsafe to drive a vehicle that stalls and won't restart.

When I slow down my vehicle begins to spudder and sometimes turns off. At first I thought it might be the fuel filter which was changed but problem persists. The vehicle has shut down on the highway when I slowed down for traffic. I place it in neutral while still in motion and turn it on again then immediately put the vehicle in drive to avoid getting hit. I first thought it was just my vehicle until I came on her today and found other people with similar problems.

2005 Chevrolet Colorado 102,000 miles. Vehicle flashes "reduced power" on information display then shuts down engine. Luckily I was able to coast in to a parking lot out of traffic. Engine refuses to start for a couple of minutes then fires up. Has done this a number of times since. Engine code given is P0601 "check sum error", ie computer glitch. This is an unsafe condition, instead of reducing the engine so that one might get out of thraffic, the fact that it kills the engine is a major safeyt risk. Poor programming to say the least.

The conduit or wire cover from the cab of the truck to the extended cabs rear driver side door cuts wires in half after repeated door use. This prevents speaker from working and makes an airbag problem light display on the vehicle control panel.

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.
