When I try to stop the vehicle after going between 5-10 mph, the ABS system "activates" and makes a "grinding sound". it will do this after 3-4 stops and then the ABS fault light will come on and the problem stops. If I start the truck and drive faster (15 mph or faster ) then brake, it doesn't do it at the higher speeds.

I own a 2005 GMC Canyon. Three weeks out of warranty the ABS system began to malfunction. The ABS would kick in for no reason. Because it was according to GM out opf the guarantee period there was nothing they could do for me. My private garage told me that this was a common problem with the Canyon and used a work around to solve the problem by disabling the ABS system because of the high cost of replacing the sensors witch would probably be damaged again when replacing the brake pads.

ABS fault comes on intermittently and GM is not responding to our concerns.

2005 GMC Canyon, 4WD. Brakes lock up after sitting for a short period of time or when wet. ABS does activate, hear the noise, rear brakes lock. Went to some of the forums for these vehicles, find out it is common. Took vehicle back to dealer (bought it used as certified GM) as the parking brake stuck only a week after I had the vehicle. They replaced the cable, told me I was set. I took the truck home, brakes were very "touchy" brought it back to the dealer a few weeks later (thought maybe it was me) and they charged me $100 and said they adjusted the rear brakes, not under the warranty. I called them and had a blow out argument with the service manager to no avail as the brakes were still touchy. I have been living with them until today, when in the rain I had to make a panic stop on the highway. The brakes momentarily locked at 65 mph, truck stayed straight and I was able to let off fast enough. Luckily the guy behind me was not following too close, or he would have been under me. Situation is getting worse, I have been driving for 35+ years and never had a vehicle like this.

Rear brake shoes bad at 45,000. Replaced drums and shoes. New drums warped after 2 months and 2,000 miles. Replaced drums and shoes again, squeaks very loud, drums bad again. Replaced drums with GMC drums, brakes bad again after 1 month. Took to an independent mechanic after dealer would not fix issue. Independant replaced left rear hydraulic and new shoes. Stated the emergency brake must be defective. Brakes are now squeaking again after 1 month. Also slight locking up when backing up after rain, cold, moist weather.
