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.

The brake lines are so corroded there are holes in them and now I have to replace them. I am lucky that no one got injured.

I applied the brakes on my vehicle in the driveway and felt a pop and the brake pedal went to the floor. I pumped the pedal a few times and it went to the floor each time. I looked around the vehicle and there was a puddle of brake fluid under the drivers side rear door. I felt around the frame where the leak was and felt a very corroded brake line. I searched online and found that many GM truck owners have had this problem and there is an NHTSA investigation and engineering analysis. I'd like to know if GM is going to recall these trucks for this issue.

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.

Total failure of steel brake line (front to rear) while pulling out of a parking lot after a doctor visit I was shocked to feel my brake pedal go to the floor, luckily the split system allowed me to stop before entering a busy highway. Car was towed to a local dealer for repair the owner says this happens alot after paying a $250 bill I was on my way considering risks envolved I feel manufacturers should be made to by law to use stainless material for all brake components. They must now be using a low grade steel (no doubt to cut manufacturing costs).

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 National Highway Traffic Safety Administration 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.

I lost braking on my 2001 GMC Yukon 4 wd twice during the last month, first time I had 3 brake lines replaced that had failed due to corroston, then a week later another brake line failed while I was towing a boat. I had to down shift to prevent a crash. I have spend over $1500 replacing ABS sensors, brake lines, rotors and emergency brake parts, all failed from corrision. Nothing but brake problems with this Yukon with only 36K miles.in the repair shop now.

While performing regular maintenance on my 2001 GMC Yukon 4WD 5.3 ltr, I observed severe corrosion of brake lines at both front and rear of vehicle. Corrosion is so severe that perforation is likely to occur at any time, potentially resulting in complete brake loss.

Recalled' anti lock brakes 2001 GMC Yukon

- Howell, MI, USA

Checking for ABS and brake light on. Replaced electronic brake traction control module.

- Kingston, OK, USA

I have a 2001 GMC Yukon SUV. The ABS controller module went out at 22, K miles and cost $1900 to replace. At a GMC dealer and was not covered under warranty although the car was still in warranty. This week at ~45K miles it went out again and cost $1750 at a local garage. Some thing is definitely wrong when two such modules fail in such a short time. There is a very definite safety issue here. I am a very conservative safe driver but have learned on the internet that such failures are common. A recall should be required of General Motors!

I would like to report the catastrophic failure of the brake lines on my SUV. While driving home from work, the brake light on the dash illuminated, the breaks felt a little soft upon braking. Took it in to the shop for evaluation and was told that the brake lines from the ABS to the rear breaks had ruptured. This occurred at 54,444 miles on Aug 16, 2007. Approximately 8 months later, the same situation happened, brake warning light came on and brakes felt spongy. Took it into the shop and was told that the brake lines from the ABS to the front brakes had ruptured this time. This happened on 3/28/08 and 58,921 miles. All lines were fabricated and replaced. I have had no additional problems since the repair.

The brakes were replaced at the dealer about a year ago. There is an ongoing investigation, the number is PE05020.
