2004 Chevrolet Avalanche: ABS light or ABS activating

Filed Feb 29, 2016 · 130,000 miles · CA

My vehicle has a kelsey hayes ABS module that has already failed twice. First at about 75.000 miles and now at 130.000 miles, always while driving. The module was recalled in 2002 and the manufacturer was given a chance to redesign it, but it is still a bad part. The blogs are full of owners constantly complaining about this. I had to take gm to the mat to replace the first one since the truck was manufactured after the first recall. This time around I didn't have the time or patience to do so an went ahead an replaced it out of my own pocket. Ia m also stuck with this part as it is not replaceable with any other brand. This is a dangerous glitch that needs to be addressed before someone gets badly hurt. In addition to this problem, the location of the unit (outside the vehicle and exposed to all sort of inclement environments) is ridiculous! No clever designer would have chosen this placement.

I own a 2004 chevrolet avalanche. The ABS activates almost at every stop, even on dry pavement. In researching this problem I have found that there are many complaints on-line for the same problem. I also found that there is a recall for this problem for earlier model years but not for 2004. It seems apparent that the 2004 model year should be included. I have already paid a great deal of money to have the brakes, wheel bearings and speed sensors replaced. And the problem persists. I have to exercise extreme caution every time I stop for fear of rear ending the vehicle in front of me. Any help you can provide will certainly be appreciated by myself and all those affected.

A few weeks ago the ABS and brake service light came on while driving at low speeds. It stayed on for one day and then it happened again a week later. It has gradually happened more frequently and more randomly as well. The shop has not found any structural problems and suggested that the ABS module be changed. The problem is random within the same kind of drive. Sometimes, if I stop the truck and restart it, on the third attempt the ABS light doesn't come up. There have been recalls for the 2002 models but not this year. I believe the problem still exists with other models.

The brake pedal went all the way to the floor. Fortunately, the consumer was able to bring the vehicle to a slow and safe stop. An inspection revealed all the brake lines under the drivers side door were severely rusted and were leaking braking fluid. The dealership replaced the brake lines to the front brakes, the master cylinder, ABS control module as well as the rear backing plates and right rear caliper that were severely rusted.

My 2004 avalanche speedometer and tachometer read completely inaccurate. Example=shows me going 120mph and 3000m RPM with motor off. I bought the vehicle used from a chevy dealer and was told it had warranty remaining. When the problem began last year I was told it was not warranted. I lacked the money for the replacement and have been driving it broken. Now I am finding out through other avalanche owners that it has been being fixed by dealers at no charge as there have been so many problems. I feel this should be a recall. I know my vehicle now has 110,000 miles, but I can document by law enforcement notes on a ticket I received last year that I had the problem about 30,000 miles ago. I feel this should be repaired at no expense to me. They told me when I called that their parts dept had a long waiting list for the replacement panel so you know ?chevrolet knew they had a widespread problem. Thank you. I hope to hear back from you. Also at about the same time my ABS/brake light started coming on after I drive a few miles. I don't know if it is as common of a problem or related to the instrument panel problem or not.

When I slow down at low rates of speed, occasionally the brakes began to pulsate as if in the ABS mode. I was told that it was because of the corrosion on the ABS speed sensors, located within the wheel bearing assembly, formed by road salt. This problem just appeared without warning or provocation. When operating the vehicle and low speeds, stopping distances are lengthen by 10 to 30 percent. There has been a recall on this type of vehicle for several years in other states. For some inexplicable reason, it does not pertain to wisconsin. Even after all of these years, the part to repair my truck remains on backorder. The dealer/manufacturer can only provide them if I purchased the whole bearing assembly which is quadruple the price of the part that I need. Of course, I feel that this is unfair and while I wait for the appropriate part to repair my truck, I am putting my safety, as well as others, in jeopardy (this is sad to say but I am not using prudent decision-making skills). I believe that it is fair to say that if there were not others in the area having this exact same problem, the part would not be on backorder throughout the dealerships in wisconsin. I believe that this matter should be look into and addressed and refunds given to those who have paid the enormous price of this repair simply because it is a known defect and because this defect is a safety hazards.
