Brakes failed "completely", with no warning. No "warning light" on the instrument panel while driving on a public road in the county. All of a sudden absolutely no brakes. Had recently hauled a car on a trailer from emporia, kansas. Was preparing to haul calves to the sale barn. Now that would have been a total disaster. Upon inspection, the brake lines are so rusted, that pinching off the line resulted in a rupture in another location. I was trying to get some braking action, so I could drive it to a repair shop. I'll have to haul it.

What 2006 GMC Sierra 2500 owners say
Most recent owner complaints, unedited.
Brake lines busted. This is a very serious problem because I was hauling a load and got extremely extremely lucky that it busted as I was pulling in driveway. I was pulling a loaded trailer with no brakes. This is a very common issue with the 2005 and 2006 2500 trucks. I can name 6 vehicles I know of in the past 6 months that this has happened too. Mechanic says it's a very serious and common issue that gm should be recalling. If I would have been at a stoplight it would have been bad. Cheap materials is the problem with these brake lines. 2006 year model is mine.
Tl* the contact owns a 2006 gmc sierra 2500. The contact stated that the brakes were ineffective and excessive pressure had to be applied to the brake pedal to fully stop the vehicle. There were no warning indicators illuminated. The vehicle was taken to sullivan automotive group (2406 n section st, sullivan, in 47882, 812‑268‑4321), but was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 0. *bf
In the city stopping for a stoplight the brakes failed. The vehicle luckily was able to turn into a parking lot. All fluid was lost because the brake lines failed due to rust. No brakes whatsoever except emergency brake. My state even requires a safety inspection yearly. If the consumer is not going to be notified of this serious problem at least let the safety inspectors know.
Total brake failure while trying to stop on a residential street. Vehicle towed to dealership & was told brakes had rusted out. Cost of repairs was around $2000.00
Vehicle in motion. Brake line failure (burst) while driving on crowded city street - 30mph. Pedal sank to floor. Total loss of brakes. Used emergency brake and gear in park to stop. Near collision with bicyclist.
Brake line to rear brakes rusted out.
Brake failure caused by corroded brake lines.
Brake line ruptured due to corrosion which was not visible during safety inspections. After applying brakes to stop at an intersection, brake line broke, causing a complete loss of brakes and loss of vehicle control. I had to use the transmission and the emergency brake to stop the truck. Several local mechanics commented that they are seeing an increase in the number of this type of failure on similar model years. With no failover system to stop the truck, this should be listed as a safety issue.
While driving I noticed smoke coming from under the hood and a fluid dripping onto the floor of the truck. Then there was absolutely no brakes. Pedal to the floor. I was able to get it into a parking lot and coasted in neutral til it stopped on a parking curb. The brake line had rusted through and ruptured, and the fluid was spraying into a hole in the firewall and into the cab of the truck. This is the third brake line that has ruptured in such a manner. No warning at all, and then sudden loss of braking. The warning light did not come on until the truck had been sitting for over an hour while I was waiting for a tow, and a large amount of fluid had leaked out. I'm just glad this had happened at a low speed and not on an exit ramp from the freeway. The ruptures are occurring where the lines run flat across a support. This is a poor design.
