I was driving my 2015 chevrolet suburban with 7 family members at about 45 MPH as we were coming into a city. Two of us started to hear a slight squeal like when a belt slips. After that I shut off the A/C to see if it was that. It was not. About that time traffic started to slow down in front of me. When I stepped on the brake to slow down it was hard and at the bottom of the pedal stroke. I lifted the pedal with my foot and it just fell back down. I was able to get the suburban to stopped in time before hitting the car in front of me. I had to drive the vehicle cautiously for another mile or so to find a safe spot to pull off. I had the vehicle towed 90 miles to a dealer close to a relative as we live another 250 miles away. When I talked to the dealer, he said there was a service bulletin for this issue but I believe he aid it was only covered up to 69,000 miles. Our suburban has 108,000 miles on it as we live in a very rural location. It is 45 miles on way to the grocery store. I have owned gm products all my life and have never been as disappointed in their handling of their customers as I am now. This issue with the brake vacuum pump has been a known issue and they are not covering the repair of it.

I experienced break failure at low speeds, most significantly at low RPM. When I tried to apply the brakes the pedal locked and I heard a grinding/clicking sound and was not able to push the pedal down. I experience this most when on a surface with a decline. Also when I switch the car from park to drive the car jolted forward when I took the pressure off the break. The feeling was very similar to the feeling you get when you apply heavy pressure to the breaks and you kind of fly forward. Chevrolet confirmed a leak in the vacuum pump. The vehicle has 53,000 miles. It is no longer covered under warranty. It is a very scary feeling not to have breaks. I hope general motors issues a recall to protect consumers.

In late december 2018, the brakes began to exhibit signs that they needed to be replaced. Before we could get the car to the dealership for a brake inspection in early january 2019 due to the holidays, the brakes actually totally failed to operate at slower speeds (below 30 MPH). Even when "standing on the brake pedal" with both feet the vehicle would not stop. This happened several times especially at slow speeds while backing out of a driveway or going through a drive-thru. The "brake assist light" also came on during several of these events. Also, a "grinding" noise occurred. This may have been the anti-lock brake system activating. The vehicle is now at the chevrolet dealership in our area waiting on repairs that we are concerned will not correct the problem and prevent it from occurring again. This concern is due to the fact, through our research, that there are pending lawsuits against gm and gm itself has issued several "service bulletins" addressing this issue, but will not initiate a recall of the affected vehicles. They won't even offer any reasonable solution to truly prevent future brake failure even after their recommended repairs are completed and paid for.

My 2015 suburban with approx 80k miles, started having brake problems when I would drive in reverse. The brakes had a grinding noise and was getting hard to press. The brake pads were replaced around 46k miles as I bought the vehicle used from enterprise sales. The brakes eventually got worse and had the brake assist message on dash come up. If I had to use the brakes too many times at ine time like if I had to go over speed bumps in my neighborhood, then the brakes would be extremely hard and would lose all power brakes. If I kept the vacuum up with a little RPM's- one foot on the brake and one on the gas, then I could get the power brakes to work. Now it's just totally gone. No power brakes at all now and ordered the vacuum booster and will replace it myself. I called the main chevrolet hotline and they were totally worthless. I told them about all the numerous complaints popping up on the internet and with suburbans with much less miles than mine and tried to see if they had any recalls regarding the brakes. They said no. I said they should be concerned before it ends up killing someone.

While driving, the dash message alerted me that I needed to "service brake assist." I was not using the brakes, so I started to slow down and the brakes worked, but when I came to the light, it was like pressing a rock and the pedal would not push down. I had complete brake failure, but thankfully had slowed enough before coming to the light, that I could throw the car into park. I pulled into a parking lot and tapped the brakes several times, turned my car off, turned it back on, put the parking brake on and off. The brakes worked so I began driving very cautiously and stuck to back roads and stayed under 35 MPH. The brakes failed twice more at a stop sign and a red light, while I was driving at low speeds. I drove the car one more time a few hours later and had complete brake failure every time I tried to stop. I had to either throw the car into park, or drive into a parking lot to slow down. I had it towed to a service center at the chevy dealership. The vehicle is under 3 years old, has about 60,000 miles on it, has been kept in great condition, has on time oil changes, never been in an accident, and has new tires. The car had no squealing or grinding to show wear and tear, or any other indicator the brakes would fail. The dealership maintains that this is not covered because we are out of warranty, however, we have an extended warranty that we are using to fix this issue. It is unkown the exact cause, because it is at the shop awaiting diagnostics.

Bought a used 2015 suburban noticed a vibration you can hear and feel between 40-60 MPH. Tried to get it fixed but no one knows what is causing it on 4th visit to get it fixed right now have had it for 3 weeks tried to get dealer to take it back and they refused after fixing brake rotors. It is also having problems downshifting. Randomly. Will downshift while maintaining speeds of 50-55 MPH to 38 with no warning will make grinding noises and am unable to steer or break. Afraid my family is going to get rear ended while it's happening. Can't accelerate or do anything while it's happening. Do not feel safe driving my family in this car but it's what we have...
