  • 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
  • kpokpo Posts: 24
    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.

    What was your outcome from GM and any other source?

    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,

    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.
  • n9cvn9cv Posts: 30
    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.

    Good Afternoon Marroe,
    I seen your post and wanted to try to clarify my position and the ways I am able to assist you all. I'm part of a new department for General Motors that reaches out to customers via social media (including forums like this one, Facebook, and Twitter). In doing this, we're hoping to assist customers who otherwise might not contact us regarding a particular situation. In some ways, I acknowledge that my responses are perhaps limited in depth and scope. I am operating entirely from the GM-approved resources available to me, and when it comes to trouble shooting some problems an owner's manual is the only thing I can contribute from. Our approach to diagnosing concerns is that our dealerships are our eyes and ears, and that an in-person look at a vehicle is more accurate than a virtual one. We'd rather not have one representative of GM say one thing over the internet and another representative of GM say another in person at the dealership.
    Some things I can help assist with are:
    1) looking to see if there are any open safety recalls that you need to be alerted about
    2) inform you of your warranty parameters (exact date/time of expiration, special coverages, etc)
    3) investigate past service history in the event of a vehicle concern (an extensive service history record helps build a case towards GM assisting with the costs of a repair, but isn't the only determining factor)
    4) helps to build up our database so that the interactions I have with you virtually are recorded for "text-mining" of customer service records; this assists with GM issuing recalls or service programs for makes and models of cars

    I hope this helps to clarify our purposes for engaging with forum posts. Again, I appreciate this feedback. I am here to serve you all in the ways that I'm able to do so. If you have a question please feel free to address me on the forum or send me an email at SocialMedia@GM.com, and I will do my best to find the answer for you, or lead you in the appropriate direction.
    Sincerely,
    Christina

    Hi everyone,
    I purchased a 2006 Chevy Colorado about 4 years ago. About 2 years ago i first experienced the ABS fault issue. I touched the brake pedal to slow down and the vehicle veered off to the right, i corrected it in time but what had happened is the ABS activated for some reason but was only working on the right side of the vehicle. The ABS stayed activated for a few more seconds while i was trying to slow down, then it released and the ABS BRAKE FAULT message came up. I then had full control of the brakes. After shutting the truck off and restarting it the error message was gone. I took it to my local GM dealership (while i was under extended warranty) and they said that nothing was wrong. It happened a few more times over the next few months so i tried again, same result from the dealership. I then took it to Les Schwab, and they replaced about 1000 dollars worth of drums and pads. Also ever since i have had the truck there has been a pulse in the brake pedal. A few months later, same thing. So back to the dealership i went. When i purchased the truck in 2008 i bought a 5 year 100000 mile extended warranty. What i was not told in 2008 is that, that specific warranty starts with the vehicle manufactured date. So by this time my warranty was over (2 and half years and 40000 miles later). I threw a fit in the store and left never to go back, just decided i would live with the ABS FAULT problem. In the past week the problem has got very bad. Almost every time i stop it happens, this last weekend it happened at 75 mph and just about threw me off the interstate. Its been doing it daily, and is getting very annoying. Is there a solution to this Fault yet that anyone knows about, because we all know that GM will not man up and fix it. I'm sure there is no way that their design would ever have this many problems is the way they see things. Anyway long story short i hope that GM will fix this problem. But the way i was treated at the GM dealership in Twin Falls, ID i will most likely sale my truck and never buy a GM product again.

    Hi Strick~

    How scary that must have been having the ABS problems at 75mph! Thankfully I have only had problems at low speeds. I have been keeping a log book in my truck for every time it happens and today again coming off of the highway I could hear that sound coming from somewhere under my dash and then the ABS brakes kicked in with no fault lights on the dash. I frequently travel 300 miles on the highway to my destination and really getting worried about the safety issues and wondering when Chevrolet will realize the magnitude of our problems with this issue and do something to make it right. I refuse to pay 1000.00's of dollars to have something fixed that is not the problem or continue to have it diagnosed and pay for no readings. I have to travel this week and wondering if I should just pull the ABS fuse again?? Does anyone know if that will do the trick? I have done it before and didn't seem to have any problems but unsure if that was just coincidence. I put the fuse back in to pass inspection. I am going to attempt to call Chevrolet tomorrow and see what they have to say. So sorry that we all have to deal with this and for the dealerships not even standing behind us. Be careful!">
  • n9cvn9cv Posts: 30
    The ABS system works by comparing the wheel rotation speeds and when it finds an anomaly (meaning wheels spinning at different speeds) it engages the ABS (The pulsing you feel in the pedal) to stop what it thinks is a wheel sliding.

    There are several components that could cause your problem but the most common by far is the wheels sensors. Things like shoes, pads, drums, and rotors should not cause this problem.

    I would start looking for a maladjusted sensor (meaning the sensor clearance is off because it is not seated properly) causing an occasional loss of sensor pulses.

    If you also have traction control, an intermittent / weak sensor will also display an occasional traction fault without pressing on the brake. The traction control system uses the same sensors .

    Initially I would scan the ABS controller looking for errors (codes). The scan might tell you which sensor is failing. A solid sensor failure will set an ABS light after initially picking up speed past 10 mph without touching the brake. These are errors are easy to retrieve with a scan tool.

    If that does not work, with the same scanner I would drive the vehicle with the ABS scanner attached and look at the output of each wheel sensor. One should be different than the others.

    You could also have a bad ABS controller but those failures are rare.

    strick,

    I thought that I was reading my own post while reading yours. Talk to almost anyone that owns a colorado they can share the same issue. I was sick to my stomach to read all of the information on the internet about this problem. It seems that a lot of people replaced the hubs the sensors and everything but the truck and it still happens. If pulling the ABS fuse stops it, I may do that to mine. I would rather have no ABS than no brakes at all. Or having just one front wheel brake working and shooting you off the road. That happened to me too. Everyone just needs to report it. https://www-odi.nhtsa.dot.gov/ivoq/

    Be careful, it scared the hell out of me.

    I purchased a new 2006 Colorado with less than 30 miles on it and my experience with the truck and Chevy/ GM and their dealers have been the same as you and THOUSANDS of other owners. Simply a nightmare of total GREED. (I regretfully traded in a very reliable Acura.) The dealers don't deal and the manufacturer doesn't manufacture. They slash!
    You said, " After shutting the truck off and restarting it the error message was gone. I took it to my local GM dealership (while i was under extended warranty) and they said that nothing was wrong." Of course, what did you expect from a Chevy Dealer; they don't care and/or they don't know how; they just want your money and as much of it as possible.

    You said, " Is there a solution to this Fault yet that anyone knows about, because we all know that GM will not man up and fix it. I'm sure there is no way that their design would ever have this many problems is the way they see things. Anyway long story short i hope that GM will fix this problem."

    Don't hope, there is no hope with either the company or their dealers. The company was in financial difficulty, because they don't manufacture a quality product and then don't back them up like a reputable company should.

    Could you imagine if Boeing (The world's largest aerospace company and leading manufacturer of commercial jetliners and defense) built airplanes like GM built their vehicles? A GM type Boeing would say after their plane crashed, " Duh, I don't believe that there is a problem; take it to our hanger and have one of our janitor dealers look at it." Their dealer would say, "There is no problem." or "We can replace all the parts that are attached to the wing that failed, including the entire fuselage and horizontal stabilizer, 'maybe' that will solve your crashing problem. At your expense, of course"
    You, the airplane owner, could always contact their Customer Service Rep and they could string you along with false hope and empty promises and then later tell you, " Our GM type Boeing can't help you."
    BOTTOM LINE: A LOSER company like GM was in financial problems to the point of BANKRUPTCY and had to have the AMERICAN TAXPAYERS bail them out. What makes us think that we change a LOSER into a WINNER by just throwing Billions of dollars at them? Would you do that for a criminal? Can you change the spots on a leopard; can you change a hawk to a dove? The answer is simply, "NO"! If you love your country, don't buy GM (you will reward the greedy and punish the honest ones) ; go to a foreign car dealer and trade in your GM (Colorado or Canyon) in and a buy the foreign car (most are made in the USA); stick them with the loser GM product that they can't even give away. Tell your friends.

    The real issue was GM's lack of follow up on a few failure prone areas. You should expect to see a few things to make it through testing and into the production models. I have no idea what they did to simulate thousands of miles in various environments but a 2004 model might be expected still show up a few missed things and maybe even a 2005 model. After those years you should expect that GM would have made engineering changes to fix those failure prone areas. Unfortunately for us and also the future for the 355 (Colorado, Canyon, I 260, and Hummer H3) product line they chose to take the opposite route. You see a lot of lip service from the GM rep here but you never hear anyone come back and say "GM fixed my problem". Instead of fixing issues Gm chose to stonewall customers and say "we have never seen the problem before" even though it is listed here and on the Colorado forum sites hundreds of times.

    GM did address the issue of the soft valve seats on the I-4 and I-5 engines by extending the warranty to 100,000 miles. They did address the failing brake light with a $10.00 recall, but other than that on these other high failure items such as the wheel sensors, the heater fan resistor, the missing star washer on the right inner fender ground connection, and the evap vent solenoid you hear nothing from them other than "you are the only one who is having this problem". It will cost you $,$$$.$$ to fix our poor design.

    GM chose to make these design failures a revenue stream rather than an engineering issue. The product line is now dead. This is the last year for them and they are shutting down the US plant that makes them. You seldom see one on a dealer's lot and haven't for a few years. So there now is no incentive for GM to resolve your problem.

    Two weeks ago I bought my first foreign car. It was a used 2009 Honda. I needed to reset the anti-theft radio code because I had disconnected the battery. I called Honda and registered myself as the new owner. They helped me with the new code and then said "Sir, there is a recall on that Honda and one service bulletin that you should bring you car in to have done. Your nearest dealer is xxxxxx and I can transfer you there if you would like to make an appointment." I never asked for any of this. All I wanted was a radio reset code but they went out of their way to make sure I knew what additional "free" things should be done.

    I've always owned GM vehicles and GM was customer oriented is in the past like Honda is now, but Gm is not that way today. Good luck on resolving your issues. I now have 5 GM vehicles and one Honda in my family. You can bet that ratio will continue to change in the future until all of the GM vehicles are gone.

    Amen, you stated it exactly as I read this forum. You get no where here!
  • tammy72tammy72 Posts: 6
    Yes, I pulled the fuse and the problem is solved. I have to enjoy my truck with the abs and brake light on all the time, but it's better than the brakes not working. My truck was inspected this way at the GM dealership, because they are aware of the problem and that GM is doing nothing about it. It di!d pass inspection even though this is clearly a safety hazard!
