In aug 2005, the ABS light on our 2001 gmc yukon with 51k miles came on and there was a grinding noise (the pump) underneath the driver's side which remains on when the vehicle is turned off. The ABS fuse must be removed to shut off the pump. Our local gmc dealership repaired it for $1100 ($870 for the ABS module). In sep 2009, the ABS failed again at 91k miles. Our gmc dealership helped cover the cost of repair by covering the cost of the module. We had to wait 2 months (nov 2009) before the vehicle could be repaired because we were told that the module was being redesigned to fix these problems. In oct 2014, the ABS failed again at 138k miles. Our gmc dealership put us in contact with gmc customer service with the hope that gmc could assist in covering the cost of repair. After several frustrating phone calls with supervisors, we were told that the vehicle was too old and therefore gmc would not assist. During these phone calls gmc stated that there was a recall for the vehicle in "salt-belt" states but not california. Obviously the ABS module is defective as a relative with a similar vehicle (chevy tahoe) had the same issue with the ABS module. In searching the internet, we found a company that states that they can repair the module for under $100 and guarantees the repair for life. If they can do this, why can't gm make the necessary changes to the ABS module and give customers the peace of mind that the vehicle will be safe. Hopefully the federal safety agency will use this and similar complaints and force gm to issue a recall on the ABS module.

I was driving my yukon in rush hour traffic when I found it necessary to attempt a panic stop. I pressed on the brake pedal and felt somthing give way and the pedal went to the floor. I attempted applying the brakes again and again the brake pedal went to the floor. I nursed the vehicle to a parking lot and looked underneath and found brake fluid dripping from the frame on the drivers side just before the rear wheel. I inspected the brake lines and found them to be very corroded and the one line leading to the rear brakes was split open. I have since replaced the brake line from the ABS unit under the drivers seat to the junction near the spare wheel. I have inspected the other brake lines and found they are corroded also.

Abs system activates during braking, making the vehicle almost unable to completely stop. When calling gmc, I was told that it was not covered under any recalls.

Abs light came on when backing out of driveway. Drove 3 miles to a meeting. When ignition turned off the light went out but I could hear a hum. Unable to locate source of hum. Spent 5 hours in meeting and hum was still present. Car started ok but ABS light came back on. Late in day so I took to local firestone service. They determined it was the ABS pump. It was so hot it blistered my finger when I touched it. Tapped on pump housing to get it to go off but no success. Only way to stop pump was to remove fuse from fuseblock under hood. I am glad I discovered this. If it had been my wife the car most likely would have been put back in our garage without notice of the hum. May have caught fire. Are there any examples of this model, or other models having same or similar ABS pump and ABS computer, catching fire? There is something wrong with the circuit logic. It should "fail safe", I.e. Detect this malfunction and disconnect power. The part has not been removed; it has just been disabled by removing fuse.

Slow speed stop approaching a locked gate. Brake pedal was applied. Pedal dropped to the floor with complete loss of brake pressure. Brake pedal was pumped twice with the final application locking one rear wheel. The above vehicle stopped within 2 feet of striking a metal security gate. Brake fluid was observed dripping from under the drivers side compartment on to the ground. Vehicle was towed to my mechanic. Mechanic found that there was excessive rust on all metal brake tubing. One of the metal brake lines from the master cylinder to the ABS pump completely rusted through causing loss of all brake pressure and brake failure. All metal brake lines had to be replaced. Before and after the incident there were no warning indicator lights that were activated on the dash.

I own a 2001 gmc yukon and this is the second time the ABS module has failed on it. After it fails, the motor continues to run. Not only do you not have ABS, but the motor heats up. If you don't notice it right away, it will drain your battery, leave you stranded, or worse.

Recurrence of antilock-brake problem which was cause of an earlier gm recall of this same vehicle. Earlier recall resulted in a 1.5 hour task to remove, clean and re-install ABS sensor with a rust-preventative applied. The same problem is recurring now and gm customer support refuses to re-address the problem on my vehicle. Background: in april 2005, the federal safety agency opened an investigation of more than 1.2 million gm pickups and suvs in 20 states because of questions over the antilock brakes. In 2005, gm spokesman alan adler said road grime can wedge its way into a plastic piece that covers the ABS sensor near the wheel hub, resulting in salt corrosion. The corrosion leads the sensors to activate the ABS system at speeds of 3.7 miles per hour to 10 MPH, requiring a longer stopping distance. Gm said there have been 228 crashes reported through the end of may 2005, including 10 minor injuries. The company recalled about 150,000 pickups in eastern canada in november 2004 from the same model years because of the condition in the antilock brakes. Adler said the company decided to issue the 2005 recall in 14 states based upon incident rates. Gm and the government have received more than 700 complaints about the problem.

We have a problem with the ABS system on our yukon and the dealer insists that it is an isolated case but I have found multiple complaints online for the same problem. This problem is extremely dangerous since the vehicle has been designed to brake with much reliance on the ABS system. By this I mean that the 2001 gmc yukon does not have a brake proportioning valve that will redirect braking force towards the front brakes as the vehicle mass shifts forward under braking loads. This in turn causes the rear brakes to lock up prematurely under moderate to heavy brake application. It has nearly caused our SUV to roll-over on one occasion and frankly, we're afraid to simply sell it and pass the life threatening problem onto someone else. I am deeply disappointed with gmc for not addressing this deadly problem in the western states and only claiming that "snow belt" state vehicles are affected. Please help us and others that have been through the ringer with multiple gmc dealership service centers that refuse to admit that there is a glaring problem. Thank you.
