I was driving down highway and saw a wall of cars and brake lights in the distance, so naturally my foot tried to push the brakes. The pedal was hard, and I panicked because my tahoe was not stopping at all! I continued to stomp on brake pedal all the way until my car actually hit 3 vehicles and then the guardrail! My brakes did not work , because if they did then I would have easily prevented this accident!!

Purchased the car new for a local dealer in Surprise, Arizona. Over time the brake pedal has become spongy, soft and pulsating. This happens mostly at slow speeds like backing out of the driveway or garage. Did a search of the federal safety agency web site and see that there was a recall on my model year vehicle to replace or reprogram the vacuum pump. However I never received a recall notice. I am now afraid to drive the car because I am concerned over a complete brake failure. I do know that during one of my normal service maintenance appointments I was approached by the service advisor about his concern over a suspected brake issue. He wanted to replace my entire brake system, master cylinder, vacuum pump, etc for a cost of about $1,500 as I recall. I declined the repair as I was not aware of that the problem I was experiencing was including in the recall. Again I never received any notice of a recall of the vacuum pump for the brakes but clearly I am experiencing the symptoms as was described in the recall notice on your website.

Brakes failed to work at low speed. Traveling in stop and go traffic on I-40 and the brake pedal became hard as a rock and was pulsing. Had to pull over and coast to a stop. Performed a test on the median of the highway and again the brakes failed to work. We were towed to the repair shop. Awaiting the repair diagnosis and cost.

On january 29, 2021, my 2016 tahoe lt, with 69,676 miles, experienced a "brake vacuum assist pump failure". The vehicle was on a flat surface (driveway), in reverse, moving very slowly backward, when I engaged the foot brake pedal it was hard and would not stop the vehicle immediately, the vehicle eventually stopped after an abnormal distance (without warning the brakes failed to engage). Once I stopped, I turned off the ignition, waited a few minutes, then started the ignition and no warning sensors/ lights were displayed. I then placed the vehicle in drive to check the brakes. I moved forward slowly, when I pushed the foot brake pedal it was once again hard causing me to pump the brakes which caused the brake pedal to become fluttering and the pedal was pushed to the floor, the vehicle eventually stopped after an abnormal distance (without warning the brakes failed to engage). Because of the severe safety risk, I had no choice but to replace the 'brake vacuum assist pump' on february 2, 2022, at my cost.

As I approached a red light the brake pedal depressed nearly to the floor and with no warning a popping noise sounded from the vehicle followed by the brake pedal suddenly depressing completely into the floor. I was able to safely pull the vehicle to the side of the road and get the vehicle to a safe location given the lack of braking abilities. This is a several ton vehicle and I expect the brakes to work at all times. This is unacceptable. I brought the vehicle to the dealer once before to remedy this recall but it was clearly not fixed. The loss of braking ability was followed by a message on the dash stating "service braking system immediately", followed by "service brake assist". A light illuminated on the dash as well and I am unsure of the specific meaning of this light. A second light showing "ABS" was flashing to also catch my attention to the current issue at hand.

When driving at slow speeds, particularly to park, the brakes did not work. You can put the pedal to the floor and the vehicle keeps going. This only occurs when at a slower speed, in both drive and reverse. I have taken it to a mechanic and the vacuum pump has to be replaced. This is very dangerous and could have caused an accident, as I almost hit another car because I couldn't stop.
