Chevy Colorado and GMC Canyon ABS Fault Issues

  • Simple reason: it's economics ... it's cheaper to pay minimum wage folks to say "I'm sorry" multiple times than it is to pay a good engineer to to design it right, or if the engineer did his job, then the parts buyer ignores the specs. and buys the cheapest brake parts possible from the Chinese who use the same raw materials in their brakes as they do in dog food; no wonder GM brakes howl and the pet food is poison!

    I'm up to $1100. Beariings and sensors have been replaced on both side of front. Still getting the ABS fault signel; this included new seals on the axles which was only a minor part of the cost because everything else needed to be removed anyway. I admit this problem has existed for a long time and as you have indicated appeared to be ambient temperature related. I experienced problems when the outdoor temperature raised to about 40 degrees. Sensor did not go off all winter. What is the fix?
    The signels are almost continuous at this point.

    The problem is almost always a clearance problem between the sensor and the part that it is sitting up against. The sensor a develops a very low voltage pulse as the steel teeth of the gear like part passes by it.

    Usually these failures can be fixed by simply tapping the back of the sensor in a bit with a plastic hammer. There was never a GM spec released for the sensor clearance because GM never intended to sell the sensor by itself.

    Occasionally this can also be attributed to rust on the gear like part that passes in front of the sensor. In that case the sensor needs to be removed, cleaned, and reinstalled again.

    It is rare that the sensor itself is really bad.

    Thank you n9cy! Can't believe it could be this simple. Will try this.

    You are talking about problems at warmer temps I have not seen anyone talk about the computer that controls the abs system some computer problems are affected by the temp and for both wheel sensors to act up at the same time it could be more of a computer controller problem than both wheel sensors Case in point I had a 2002 Gm that had an engine problem one fall and it would throw a code and I tested everything I could and then it went away all winter and when it started warming up in spring it started to recur again I then took a chance and replaced the ECM and problem went away The Colorado I was checking out tonight also had a code Y 1064 which involves the chassy controller which might be used to control the ABS that what I'm trying to find out now

    Why do you think that GM never tells the dealers to clean, adjust or tap the sensor? In stead they charge the owner $1100 (or more) to blindly replace both parts (as indicated by more than a few owners) and the problem seems to more often remain unsolved.
    Why would a manufacturer sell a vehicle to the public, after 75 years of making vehicles, that leaks water into the back window and then expects the owner to pay to have the faulty seal to be fixed. Is the faulty seal going to be replaced with another faulty seal that they make and will soon leak like the original part? I would like to know what GM is thinking about these lack of manufacturer quality parts. Do they just want to get us to keep paying them so the corporate executives can take bigger bonuses and get another "Bailout" to line their pockets?

    It is all about money.

    The repair decisions are being made by the mechanic (technician) at an independently owned business (the dealer). The mechanic is being paid by the book and not by the hour. He gets paid more when the work is billed outside (to the customer) rather than paid for my GM (warranty work). The dealer also makes the mark up on any parts used so the more parts used the better for the dealer. If it is warranty or recall work only one part may be used without specific permission of GM.

    If you complain to GM, they defer back to the Dealer to make the determination on whether you pay or send it back to GM and ask for them to pay.

    I bought the truck used, a year and a half ago. It now has 80K miles. I have been able to live with the drivers door speaker that is blown and works sometimes. I was OK with wet floors from the brake light leak that I have fixed. I am OK with the radio that is temperature sensitive and stops working at 65 degrees. The occasional non start due to anti theft system is tolerable. It has no oil leaks, does not smoke, but still consumes a quart of oil with every tank of gas. I got a faulty gas cap warning, bought a new cap and it went away. Still OK that I got a lemon, its a second car. I had brake pads put on right after I bought it. Last fall, I put new tires on it. They inspected the brakes since the wheels were off and all was OK. About a month ago I got the ABS light on the dash. The brakes worked fine and it is springtime so ABS was not needed while driving. The next time I drove it no ABS light or warning message. Then last Friday I picking up my kids from the babysitter. As I turned into the driveway, filled with cars and a yard full of little kids, (@ less than 5 mph) I applied the brakes. The pedal went straight to the floor with the chatter of ABS and the truck did not slow down. A quick application of the parking brake stopped the truck. Perplexed and embarrassed in front of a bunch of people I acted like I meant to do it. No ABS fault light on the dash. (?) I put my kids in the truck, started it back up. No ABS warning light. Drove down the road very cautiously, as I approached an intersection I went easy on the brakes. They work fine. With my confidence back, I resumed legal speeds. 1 minute later, I was attempting to slow down to make a left turn and the brake pedal went straight to the floor with the ABS chattering away. My first instinct was to pump the brakes. On the second firm pump, the steering wheel was ripped out of my hands as the truck shot to the right onto the curb barely missing a mailbox. Needless to say I did not make my turn and stopped the truck by downshifting and parking brake. Turned off the truck and restarted it. Magically the brakes returned and still no ABS warning. They worked fine the rest of the ride home. After reading these blogs I knew I needed a fault code for the dealer to analyze the problem. I cannot get it to show a code or go code less full failure. I am afraid to put one dime into hubs/sensors after reading about people replacing them and still have a problem. Any suggestions??? This thing is a death trap and spending 2 grand for my problem not being fixed does not appeal to me. Usually when things are broken they stay broken. This is a computer/electrical issue of some sort. I guess GM will ignore it until people die. I don't have the heart to sell it or trade it in so some sucker like me buys it and runs over his own kids in the driveway. I really don't know what to do next if this is a universal problem and GM won't recall them. Any advice is appreciated. Thanks.

    Thanks for the link. I will file a complaint tomorrow. Its getting late and I am sick to my stomach seeing all of these issues posted all over the place and my truck has most of the issues. It was a scary ride when the brakes failed. Then it was more scary that the issue comes and goes. I have never had so many issues on one vehicle.

    marroe,

    I'm so sorry that your experiencing this potentially dangerous concern with your brakes! It looks like it is happening quite frequently at this point - for a dealer to diagnose, they need to be able to duplicate the problem if there aren't any codes. Let us know if you decide to go in! We're available to help in any way we can.

    Sarah,

    Thank you for reviewing and responding to my message. I am glad that a representative from General Motors is clearly aware of my situation, in the event of a serious incident. I am not able to duplicate the problem for the dealer to diagnose. If the problem comes up again and the code registers, I will take it to a dealer. Unfortunately I will have to select a dealer farther from home. The owner of the dealer closest to me is a close social acquaintance, and I am confident that the situation will not be a pleasant one. I do not want to harbor bad feelings about him, his family, or his business every time I go to a soccer game, the swim club, a school event, or even at church on Sunday, because of issues out of his control or the products that he sells. I will select a reputable dealer that I have no personal ties to so I can be objective in my decisions and actions during the process. I drove the truck all weekend and the brakes did not fail. Its like driving a ticking time bomb and having no idea how much time is left or when it might go off. Sounds dramatic, but thats how it feels. Sarah, you did mention that you would be available to help any way you can. In what ways do you feel that you can help in a situation like this?

    marroe,

    As you begin to work with a service department, we would set up a Service Request through our department which would allow us to interact with your dealership to follow the progress on the repair, and if there is not a satisfactory resolution to perhaps send the case to your district specialist for further assistance. Our primary goal is to get vehicle concerns remedied through this process.

    I hope this helps to clarify our role. If you have further questions or would like to start the Service Request process, you can reach us at socialmedia@gm.com

    Best,
    Sarah

    Hi Sarah,

    If I e-mailed you my VIN number, is it possible for you to obtain the list of dealer completed service work on my truck since it was new? I am curious to see what dealership service or warranty work work was done and if any of the work done is associated with the issues that I am experiencing. I see many other owners have issues at low miles and I am wondering if mine did too.

    Thank you for your time,

    marroe

    Good morning marroe,

    I'm sorry - I am unable to disclose that information. I would be able to check into any existing recalls that are open and associated to your vehicle, but would not be able to discuss past service history prior to your taking ownership of the vehicle.

    Regards,
    Sarah

  • Hi I'm Looking or Trying to get a hold of Mariah GM Customer Service or gmcustsvc is her name Id? I'm trying to ask her some questions about my 2004 Chevy Colorado abs sensor & well a list of other things or problems. Thanks
  • Hi I'm looking for help, info, ideas, problem solving ideas & anything else along those lines. Abs sensor, heater, rough idle etc. Please help thanks.

    I suggest that you go to one of the Colorado forums and ask for help. coloradofans.com is a good one.

    www.355nation.net is another.

    A quick comment on your listed problems. The heater fan is usually a burned connection on the resistor block or a bad ground wire connection on the right inner fender. If it is a 2004 an AC cooling problem there is a fix posted there for the temperature sensor on the evaporator. The rough idle is usually cured by cleaning the throttle body. It could be other things like a coil pack or a valve but clean the throttle body first. The ABS problem is usually cured by tapping on the back side of the failing sensor and re-seating it back where it belongs. You can get more detailed info on these common problems at the above sites.

    The only thing that GM Customer Service can do is monitor your repairs after you have taken it to a Chevrolet dealer for service. The dealer will charge you just for a diagnostic check. The forums can guide you through some of the simple fixes. They have helped me quite a bit. They have no simple answers for an electrical/computer problem which GM should be liable for. The ABS issue is quite scary. If the ABS stopped working, I can live with that. This issue give you no brakes at all. Good Luck.
