While traveling to work my vehicles check engine light came on and the reduced power warning came on at which time I had complete loss of acceleration, complete loss of braking, and complete loss of steering power. I then had to coast to a stop and attempted to restart the vehicle 6 times before I was able to get the reduced power warning to go off and was able to drive although the check engine light stayed on. This is the 2nd time this has happened to me in 2 days with the loss of power. I have had the reduced power warning on numerous occasions years past but never have I lost total / absolute power to control the vehicle, this is a total death trap for anyone who has had this experience, especially on the freeway or highways at high speeds. I have read numerous accounts of this same issue affecting other gmc owners and have seen no resolutions or any recalls from gmc. I have already replaced the throttle housing and harness components, acceleration pedal sensor and yet the issue continues, someone is going to ( die ) because of gmc's lack of concern and responsibility to owners of their products. I will never ever own another gmc associated product.

I was traveling on saturday morning, in my dads 2004 yukon luckily it was early enough not much traffic at the time, it was raining and I was not driving very fast normal speed on the highway is 40 miles per hour on us11 because of congestion and traffic lights, I was traveling between 30 and 35 MPH because of rain, anyways a light changed and I had time to stop, but the vehicle did not stop the pedal went almost to the floor and the light came on stating brake failure, from that point I slowed down as slow as I could and tried to test the brakes, it would stop, but needed plenty of distance, so I slowed for a turn off, and when I got home, started to brake before entering the driveway so that I would not hit the garage or anything else, in fact I stopped the vehicle at the end of the driveway near the road.

In december 2012 we were traveling when my husband went to hit the brakes, they completely gave way and stuck on the bottom of the floor. In panic he tried every maneuver possible as we were coming up on an l curve that quickly LED to a stop sign entering a major intersection. As we made the l curve, two motorcyclists were at the light and we were coming straight at them at 40 miles an hour. Making a massive turn and risking flipping the car over, he hooked the truck to the right unto the embankment of the major road barely avoiding killing these two motorcyclist. We drove on the embankment until the car came to a stop. We called a tow truck and he towed us to a md repair shop. We then received a call from the repair man that the brakes lines were completely rusted out and that we blew the brakes line and instantaneous lost all oil. No brakes left whatsoever. He told me to call the dealer and push for a recall since that much rust was a sign of an issue when the car was made. There was no seal on the under carriage. I did and the gentleman at boyle buick said not to tow it in to their shop as it would not be covered under warranty as they see it all the time but that gm has never paid for these to be fixed on a car out of warranty and despite this being a constant issue they see- it did not have a recall on it. He even gave us the name of a company that makes stainless steel aftermarket brake lines already bended as that is where they buy them- they see it so often. This company sprung up because so many people had this exact same issue they could make substantial money pre-fabbing these lines. I kept my receipt for these brakes line ($1,235.00) as I had to believe that someone would eventually hold gm liable for not coating the underside and putting thousands of lives at risk.

Traveling on bqe 3 lane crowded highway in brooklyn when attempted to brake for exit and brake pedal went to floor - no brakes - I luckily was able to stop the vehicle on level road and avoided accident. I could have been killed. It was not my day to die but I thought it was.....then I saw the federal safety agency investigation ea 11001 and read the internet posts on this gm problem and can't believe there has been no recall....how many people need to die?

Approaching a traffic light at 35 MPH, without warning the brake pedal went to the floor. I could not slow the car down very much and went through a very yellow light. Fortunately the car waiting at the light had not entered the intersection. The a brake line routed above the frame blew apart losing brake fluid every time I pumped the brakes. No pressure to operate the rear brakes. The break occurred at a rusted location.

Brake hose in engine compartment developed pinhole leak due to heavy rust. Brake pedal went to the floor. Brake bleeder screws rusted solid- can't bleed lines after repairs. It appears that inferior quality metal brake lines were used that rust easily. This is a very low mileage vehicle. This is a very common problem with these trucks and gm needs to held accountable, and a recall should be issued as very serious crashes may occur.
