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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2004 Chevrolet Colorado Owner Comments

problem #2

Nov 012012

Colorado 4x4, Z71

  • Automatic transmission
  • 106,000 miles


I have a 2004 chevy colorado and when I engage the 4x4 it flashes and sounds like its in 4x4, but it is not.

Sometimes the 4x4 lights on the dash flash and then it goes back to 2 hi. I had the same problem last year, and I brought it to three different dearlerships and no-one could figure it out. I replaced the transfercase, and it worked fine. (Out of pocket of course) Until this winter when I went to use it again. The same problem again. No 4x4!!! Any help would be greatly appreciated... Thank you..

Colorado 4x4, Z71

  • Automatic transmission
  • 107,000 miles

When I put my truck into 4lo or 4 hi, the lights just flash and it sounds like its in 4 lo or 4 hi but it isnt. I have had it in 3 dealerships and they couldnt figure it out. They told me it was a transfer case, so I put one in a year ago, and now its doing the same thing... I spoke with GM customer service and they told me its not under warranty. (Like I didnt know that already) And they also told me its not recalled either.... So no-one knows what the problem is, and Im supposed to keep buying transfer cases and or putting my truck in the shop and wasting money and time?!?!? This is rediculious and so is this Chevy Truck... And so is Chevy's customer service... Maybe I'll better luck with a Toyota???
