Brake Sensor problems of the 2001 GMC Yukon

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.

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.

Stepped on bakes in a panic stop. Blew out rusted brake line near front of car. One by one, all of the steel brake lines are failing due to rust. I just blew the steel brake line at the rear of the car near the differential. The abs sensors have been replaced twice due to corrosion and they abs pump has been rebuit. The parking brakes on this car have been replace 4 times and have never worked correctly.

Upon applying my brakes at low speeds (under 10mph) on my 2001 Yukon xl, there is shuddering from the front and at times the brakes seem to become ineffective. It is as if the abs is pumping the brakes, but it is occurring on dry pavement. I recently ((7/16/08) brought the vehicle in for service and was informed that one of the abs sensors needed to be replaced. After being informed of this, I checked the internet and found out there is a recall due to potential corrosion of the abs sensors but it is effective for only specific states. I live in northern virginia and have driven through the affected states numerous of times during winter where salt, etc. Is used on the roads. In the northern va area, salt is also heavily used. I believe that the recall should be expanded to those state that border the "salt belt" states. This occurrence began around April 2008 and the latest incident was today 7/16/08.

2001 GMC Yukon with brake problems. Consumer states that his dad was driving and stated that the brakes weren't working properly which caused him to rear end the vehicle in front of him. No one was injured in this incident. The consumer stated the accident happened due to a recall notification that was not received. The recall was about a brake sensor that could corrode over a period of time.

I have a 2001 GMC Yukon xl. Recently there was a recall for a failure of the abs brake sensors which caused the brakes to pump rapidly at low speeds due to the seals of the bearings going bad and allowing dirt and road salt to get to the sensors. Well in early July I had no problems with my vehicle. Sometime in late July I started getting the pulsing of the brakes. I was told to wait for the recall, and was able to have the abs disabled by loosening one of the sensors. I brought the vehicle in, the dealer replaced both sensors in the front wheel hubs, but then stated the bearings had gone bad and I needed a new wheel hub. Now the car still has no abs, and has a funny feel from that wheel hub. The truck has approx 53,000miles on it. How can the recall say it is based ona faulty seal of the wheel bearings going bad, and they are not responsible to replace the seal or the bearings if they go bad due to their defect? I have contacted gm customer service a number of times and all they say is "the recall covers the sensors only, the wheel hub is a wear and tear part" and do not show how their defect is not the cause.

Gm has recalled several of its suvs and pickups due to a bad anti-lock brake design. This has occurred in canada and 14 us states of which minnesota is not included. This past fall I was having the described problems of the anti-lock brakes coming on whenever I was braking at slow speeds. This usually occurred at stop signs. I didn't feel safe with the brakes and the impending winter and decided to take it in to get fixed. They replaced a sensor saying it was bad and I paid ~$230 for the fix. Prior to getting it fixed I had onstar run diagnostics to see if there was a problem. After getting it fixed and hearing of the recall in canada I spoke with gm who said that they wouldn't do anything for me. Now with these 14 other states I am furious. It seems like they should be covering the costs of my repairs since I had the exact same problems. To pick and choose the states while compromising safety is absurd. Any information or recourse you could share would be appreciated.

Consumer called and complained about brakes, intermittently at every 600 miles average, the abs system need to be replaced at consumer's expenses. Dealer indicated that consumer needed to clean the sensor and the bearing,. Also, they stated that GMC and NHTSA has a TSB on this issues.
