Driving my car today and had a huge issue with my brakes. When backing out of parking space and noticed someone walking behind me and hit the brakes, it was like they were stuck. After a couple of seconds they finally gave and stopped, so I just thought maybe it was a fluke. This happened while I was 2 hours away from home. Then on drive back home, I got stuck in bumper to bumper traffic because of an accident on the interstate. Traffic came to a complete stop, so I hit my brakes and same thing, they were stuck (would not move). After about 3 seconds of pushing them as hard as I could, they finally gave and just barely missed hitting the car in front of me. I finally searched the internet to see if anyone else had experienced this problem. I was very shocked to see this is a known problem! this is a huge security risk! I was almost in 2 separate accidents today because of a known problem! shouldn't someone be notifying Tahoe owners of this issue to keep the public safe?

I was driving straight in the parking lot at a slow speed (leas rhan 5 miles) preparing to stop for people crossing. The brake did not work and the car kept rolling almost hitting a person. I pulled into a spot towards the end of the parking lot and the brakes continued to not work even when pressing with 2 feet. Per Chevy dealarship I have to pay to have the brake vacuum pump fixed. Minimal explanation needed when I brought my car in, service guy knew exactly what I was talking about without asking any questions.

While backing up the vehicle into a parking lot noticed the breaks where not properly functioning and took a lot of effort and pumping to stop, continued to notice a great effort and distance to stop and breaks not properly functioning due to a faulty break pump provided by manufacturer's error that could potentially cause complete lost of breaks.

During slow movement, such as approaching a stop sign in traffic, the brake pedal will get hard and there will be no brakes. This has only occured during slow movement so far, but I'm now concerned that it could happen at highway speed. The dealer offered a repair for $691 but this is a manufactureres defect that should be under recall.

While going at slow speeds, the brake pedal becomes stiff and locks up resulting in the brakes not working at all. This has caused me to almost hit multiple people in heavy traffic, parking lots, and drive through restaurant lines as well as almost causing me to roll through red lights into oncoming traffic. This has happened randomly over the past year (2018) and has recently became more common.

I initially noticed difficulty with braking while backing out of a parking space at a very low rate of speed. The brake pedal became hard and the vehicle continued to roll backward, with full weight on the brake pedal. Approximately one month later I was in bumper-to-bumper, stop-and-go traffic and the brake pedal again hard and the vehicle continued to roll forward. This issue did not occur during normal driving conditions, only at low rates of speed and with frequent, repetive stopping. I took the vehicle to a local Chevrolet service department and they were unable to replicate the issue or identify the problem with diagnostic equipment. I was told by the service manager the problem was likely due to 'over use' of the brakes and the brake is designed to be 'pumped' rather than compressed for more than a few seconds. I took the vehehicle to a second Chevrolet dealership. The service department replaced the brake booster vacuum pump and this seems have resolved the issue. I was unable to drive my vehicle for approximately 2 months due to fear the brakes would fail. The vehicle has 54,000 miles and was purchased new from a dealership.

Having issues with braking. Occasionally at high speeds, but more often during lower speeds. The brake pedal becomes very hard to depress and meanwhile the vehicle is still moving, not allowing you to stop. Happens also going in reverse. Had a collision, hit the rear end of another vehicle yesterday morning during rush hour, 3/18/2019. I was slowing down to 15 mph, due to a red light, but brake pedal would not brake, becoming very stiff, making it impossible to brake, and stopped due to the collision. Luckily no one was hurt. Front body severe damage to my Tahoe. Police report has been filed. We bought this Tahoe in fall of 2017, and February 2017, took into the dealership due to the braking issues, nothing was found or done to the brake system. Tahoe is back at dealership as of today, and nothing has been found, according to Chevy techs
