Three problems related to brake light on have been reported for the 2000 GMC Sierra. The most recently reported issues are listed below.
While towing my boat I experienced brake failure. The pedal went to the floor with no pressure. Brake warning light did not come on. We were on a dirt road with no traffic and were able to stop without incident. After inspecting the brake lines a leak was found in one of the lines under the drivers side door before the line enters the brake modulator. All the lines are rusty and need to be replaced. I contacted the GMC dealer and although they have seen the problem before they are unaware of any safety problems with the brakes and that gm has no fix for the problem. They estimate the cost to replace the brake lines to be about $1200.
: the contact stated the brake light illuminated. The contact pulled the fuse to the abs to have braking power at low speeds of 15 mph. There is an NHTSA recall, 05v379000 concerning the service brakes, hydraulic: antilock, however the recall did not remedy the problem. The dealership cleaned the sensors; however the vehicle is still having the same problems as indicated in the recall. The dealership would not offer a second repair without charge under the recall.

About three years ago I took my 2000 Sierra truck to my GMC dealer after experiencing a few low speed abs activations and brake failures causing me to drift into oncoming traffic. Since tandom log trucks are frequent travelers on our local roads, I wanted to resolve the problem right away. My GMC service manager informed me that the only way to correct the problem was to replace the front hub assemblies containing the wheel speed sensors at a cost of $500 each for parts only. I decided against that idea and opted to remove the abs fuse under the dash board. I kept inquiring at the dealer about any gm sponsored repairs and finally read about the August 29, 2005 recall notice which involved cleaning, sanding, and lubricating the wheel speed sensors. The recall service work was done on 10/13/05, according to service bullitin #05068, but my truck continued to drift into traffic as before. This time I removed the abs fuse from under the hood so I could finally use the cruise control again. The service manager has since told me that there is no authorized follow up procedure other than to replace the hub assemblies or speed sensors, at my expense. The brakes function adequately without the abs fuse, but the red brake failure light on the instrument panel is on continually, as well as the amber abs light. If I go back to removing the interior abs fuse, the red light will go out and should be available to indicate any other cause for brake failure, but I sacrafice the cruise control. Gm has admitted that they designed a defective abs system that is prone to rust and corrosion in certain "rust belt" states and provinces of canada and they are aware that these vehicles have been unsafe to operate. The ineffective recall repairs to my truck cost general motors $46. 88 on the invoice and yet they expect me to pay about $1,200 to really repair and replace their defective parts. I don't think so.
