#352 of 379 ABS Fault in 2005 Colorado Z71 Crew cab
Aug 08, 2012 (8:17 am)
WOW! I just found this site because I was looking up my ABS headaches with my Colorado and see all of the posts that describe EXACTLY what is happening with me. It is heartbreaking because I bought what I thought was a perfect truck for me two years ago. A 2005 Colorado crew cab Z71 with only 30k miles! I began having the ABS problem after about 4 months and it has been going on since. My mechanic thought that it might be caused by the excessive rust (that the dealer also had concealed very well with undercoat paint) in the area of the ABS sensors. But after reading all of these posts, I don't think that is it. My symptoms are the slight noise first, then (usually at slow speed stops), the ABS activate, the warning bell sounds, and on comes the light and fault message. It can stay on for minutes, hours, or days at a time, and then can stay off for the same. Also heartbreaking to know that Chevy isn't doing anything to help us out. I pride myself in buying American, but this doesn't help to bolster my reasons for doing so. I guess I'll watch for updates on this site from now on. Thanks.

Have you had this looked into by one of our GM dealerships in addition to your mechanic? I understand if this isn't a viable option, just wanted to let you know we'd be willing to follow up on any diagnoses performed with us.

Pequea, Please ignore any answers from "GM Custsvcs" on this site. They have no genuine intention of getting your problem fixed. If you go back through the pages here, you'll see what I mean.
Now, as for your ABS fault problem: I've experienced the same things with my 2005 Colorado for several years now, and have learned to live with it. The ABS Fault indication always goes away when I shut the ignition off and start up again. Until the vehicle becomes totally inoperable because of this, I'm gonna keep on driving it. I really do like my truck and have had no other problems in 7 years other than an oxygen sensor replaced. It really causes no safety concerns for me as long as the brakes work, especially when I read here about folks who've paid thousands of $$ to have the ABS system "fixed" and are still getting the fault code. You ought to consider the same thing. Good luck.
#355 of 379 GM Tactics
Aug 09, 2012 (7:00 am)
brewerguy and pequea,
Listen to all of the Colorado owners who have tried to be honest and fair with GM. The GM Serv Reps and GM don't do anything but use delay tactics. 'Tactics, then, are isolated actions or events that take advantage of opportunities offered by the gaps within a given strategic system.' Their strategy is to wear you down with delays, expensive diagnostics at the dealer, and multiple statements or comments of "I'm sorry" followed by a explanation of why GM (Chevy) Will Not do anything with the design and manufacturing flaw that they continued to create and manufacture for several years and that still exsists with the Colorado ABS Failure issues.
Chevy Runs Deep!?? How about: Chevy runs away! or Chevy runs deep into your pocket!

The last post is not only an angry Colorado owner, but also someone who is not afraid to tell the truth about a situation with a greedy, self serving and profit-only motivated bureaucratic corporation. Could their lack of customer focus and loyalty be the reason why they almost went Bankrupt. What goes around, comes around. You sew what you reap.
#357 of 379 Fix your own ABS!
Aug 09, 2012 (7:54 am)
Since GM will not do anything to resolve the ABS problems on their vehicles I suggest to everyone here that you either fix your own or find a competent independent mechanic to repair your ABS. I bought both bearing hubs with sensors, brake rotors, pads, and calipers all for around $600 and did the entire job myself in about 6 hours. On a scale of 1 to 10 I would say the job has a difficulty of 5 or 6. If your mechanical skills are lacking you should be able to have your mechanic install the parts for about 6 hours labor charge. If your brakes are newer you will not need pads and calipers but I would suggest replacing the rotors if they haven't been replaced while it's apart.....your mechanic should know this.
I shopped the best deals on parts both on the internet and local parts stores. With all these parts replaced the ABS works as designed and the brakes haven't given me any trouble in 30k miles. Anyone suggesting you drive your Colorado with the ABS light on is suggesting you risk your life. The ABS system DOES NOT WORK with the light on and, as noted by many people on this forum, malfunctioning ABS can cause dangerous situations.
For those of you waiting for GM to do something about your ABS problem, Good Luck with that!

Unfortunately everyone here has about the same story with the same experience with GM service. The Customer Service Rep that monitors this site appears only to be doing damage control for GM. I have never seen any posting here from anyone that came back and said that GM "fixed their problem for free" after contacting GM customer service for help. It is always take it to a GM dealer who charges $100 or so to read the Tech 2 scanner and tell you what you already know and that is the sensor(s) are failing. Then for another $500 or more per side we will fix it for you. I also monitor 2 other GM Colorado/Canyon forums. The story is the same over there.
A few years and 40,000 miles ago I "fixed" mine by re-seating the front sensors with a plastic hammer. Now it is starting to do it again. I have seen it twice this summer when the Outside Air Temperature was over 90 degrees F. Unfortunately during the second occurrence when I looked down at the Instrument Panel to see what the alarm was on the display, I missed seeing the traffic light changing to red in front of me. When I realized the light was red and tried to stop, I slid sideways into the intersection. Luckily the cross traffic had not started across the intersection yet so no damage was done other than maybe some flat spots on my tires. When you get the alarm, the ABS is shut off and that truck is very hard to keep headed straight in a panic stop without any ABS.
#359 of 379 2005 CHEVROLET COLORADO BRAKE SENSOR
Oct 26, 2012 (12:11 pm)
I HAVE BEEN HAVING PROBLEMS WITH MY LEFT FRONT BRAKE SENSOR FOR 2 YEARS, I HAD THE SENSOR REPLACED, BUT THE LIGHT STAYED ON SAYING I STILL HAD PROBLEMS WITH MY ABS.
I TOOK IT TO A MACHANIC HE COULD NOT FIND ANYTHING WRONG WITH IT. I FINALLY TOOK IT TO A CHEVROLET DEALER AND THEY FIXED THE PROBLEM, EVEN IF IT DID COST ME 900.00. IT WAS WORTH IT TO FINALLY HAVE IT FIXED. THEY HAD TO REPLACE THE HUB AND THE SENSOR,ROTOR AND I HAD TO HAVE BREAK PADS PUT ON. THEY FOUND OUT THE BEHIND THE SENSOR IN THE HUB , THERE WAS A PLASTIC BEARING (STUPID TO HAVE A PLASTIC ANYTHING AROUND THE BREAKS) THAT HAD MELTED AND WAS IN THE HUB AND THEY COULDN'T GET IT OUT, SO THE HUB HAD TO BE REPLACED. SO FAR EVERYTHING IS WOKING GOOD. HOPE THIS HELPS. I ALSO AM GOING TO CONTACT GENERAL MOTORS AND LET THEM KNOW WHAT I FINALLY FOUND OUT ABOUT THIS PROBLEM.

Welcome to the land of GM/ Chevy ineptness and design flaws. We (Colorado owners) have all had the same ABS problem(s) along with many other issues and problems that are examples of premature wear and / or design flaws. I am not surprised to hear that you found plastic parts in the brake assembly components. All GM wants to do is have the dealer replace the hub and sensor and call it a 'wear and tear' issue. The hub and sensor was re-designed in later years so you would have two separate parts, but dealers are still replacing BOTH parts sinc e they don't know what they are doing and simply want to make more money off of the owner/ consumer. Of course we will almost do anything to avoid the death defying episodes of BRAKE FAILURE due to this ABS issue. It will take a few deaths to get somone at GM to "own up".

We're glad to hear that the dealership helped you get to the bottom of the brake concern you had been having on your Colorado. Keep us posted if anything should come up as we're available to follow up on this with you and your dealership (we can be reached via email at socialmediagm.com and ask that you include your name and contact information, as well as a summary of the situation and the last 8 digits of your VIN).
