On 3 separate occasions, my brakes failed me causing me to almost crash. The first time, I was stopping at a stop sign from going less than 5mph (I was inching up after about 10 cars were in front of me). I had my foot on the brake the whole time and never accelerates and all of a sudden, the truck wouldn't stop. I was on about a very slight downhill (maybe 1 degree). It felt like the brakes became slippery and just sounded awful. I came within a few inches of the car in front of me and almost rear ended them. The next occasion, I was going downhill and to the left and has to stop. The truck did the same thing where the power brakes seemed to fail or the brakes just didn't want to work. This time I was going about 35mph and had to swerve into the wrong lane to avoid crashing. Thankfully nobody was coming otherwise I would have had to rear end the person in front of me. I was probably 5 or 6 car lengths behind him when we both hit the brakes at the same time. The 3rd time this happened was this morning in the same spot as the second incident. This time, I was testing the brakes. I'm very scared that something is going to happen because of this and would like to get this fixed asap. I bought this GM certified vehicle about 1 month ago and should be in good mechanical condition. These 3 incidents happened in a 10-14 day span and 2 times in the past 3 days.

While attempting to brake at low speeds the brake booster and pedal failed causing me to use excessive brake pressure to get the the vehicle to stop. Due to this I was almost involved in a crash the vehicle only has 50K miles.

I stopped to eat at a restaurant and my brakes got extremely hard and my truck did not stop I used both feet to jam the brake down as hard as I could to stop. There was a car in front of me but it was pulling out as I pulled in. My truck would have struck this vehicle if it weren't for them pulling out. I went directly to a nearby mechanic to see what is going on with my truck. They told me the vacuum pump is faulty and that GM has a bulletin about this issue. So GM is aware of the issue and knows their vehicles are dangerous to its customers and the public. But they have not ordered a recall to fix the faulty vacuum pump.

The brakes have failed to stop the vehicle in 2 separate occasions in speeds less than 5 mph. The has been reviewed by a certified Chevrolet mechanics and they since they cannot replicate the issue, they don't feel it is a major concern. I want to ensure that others are aware as I have stopped driving the vehicle due to the safety concern. I am currently working with Chevrolet to turn the vehicle back into them since I do not feel safe driving it.

Was going down a steep hill in Kentucky in stop and go traffic and without warning the brake pedal got really hard to push and the truck didn't want to stop. Also happened at a low RPM going down the approach of a driveway. I am able to duplicate it. Also at red lights if I pump the brakes they become really hard to push.

The brakes fail(periodically) at low RPM due to vacuum booster pump failure. Typically happens when moving slowly at idle - rolling down a driveway etc.
