At low speeds (less than 10 mph) brakes (ABS and power assist) have failed when in reverse on slight incline. Most recently (4/20/2021) the same issue occured when moving forward, at approximately 5-7 mph, while on approx 8% downhil grade. The road surface was non-paved, mixed dirt/gravel. This issue occured multiple times, however, during 2 of the occurances the vehicles would not come to a complete stop and was thought to have continued over the edge of road into canyo if not for an extreme choice forward path to navigate thurn. This "road" was the white rim road in canyon lands national park, Utah.

Even with the recall done the brakes do not stop the vehicle on the second brake application if you are at slow speeds. If you brake at slow speeds release the pedal and brake again you virtually lose all brake power.

Yesterday while driving at a low speed, slowing to a stop, the brakes felt very hard and difficult to press to stop. I continued to drive for the remainder of the day and it seemed to stop fine at higher speeds but slowing out of driveway or into parking lots it was very difficult to stop. Even at stop signs, I had to start hitting the breaks well ahead of the sign in hopes that it actually stopped by the time I got to sign. It seemed to get worse. Called dealer and left message. Called again and service department was closed for the weekend. Likely it will need to be towed to the dealer. I don't think it is safe to drive.

Braking systems not working properly. The vehicle failed to stop when applying the brake pedal. All brake pads are good; brake calipers are new; brake fluid is at max. I replaced everything I found online, but the issue is there on the vehicle.

At slow rate of speed, pulling into parking spot or in drive-thru lines, the brake pedal takes effort to push, ticking, clicking and grinding sound and the brake pedal begins to vibrate and very hard to push down to stop the vehicle. I see this has been recalled on other vehicles but not my particular Tahoe ltz VIN# this has been an ongoing issue since September 2019 after the car was purchased.

When trying to brake at low speeds the brakes lock up and feel like you or pushing through concrete. It is terrifying when you are coming down a hill, pulling a trailer, with your kids in the car. This happens frequently! I have had the brakes pads and rotors replaced with no changes. Pretty frustrating when you spend $50,000 on a vehicle and no one can tell you what the problem is.

I pulled into my driveway... the engine speed started increasing and simultaneously the brake pedal sunk into the floor and braking abilitywas lost. This happened about 4 feet from my garage door and this caused my truck into the garage door. I have a driveway video of me on the phone and then the car being accelerated through the garage door.

When driving at slow speeds (restaurant drive-thru, stop and go traffic) I often find myself having difficulty pushing the brake pedal, as it is extremely hard to push down the pedal and the car will not come to a stop for 2-3 feet. I feel a strong vibration during this and a low pitched crunching sound, and cannot push the brake down. I am afraid I will have a collision. I did the 2019 recall in which the dealer recalibrated something with the brakes. But it I continuing to have problems, I took it back to the dealership to test the vacuum pump, but they said the "testing was normal" and they were not willing to drive it long enough to replicate the problem I was having, saying that it was worn rotors and brake pads that were causing the issue. I know what the car feels like when the rotors/pads need changing, and I do have slight vibration when braking at high speeds, but never where I have increased brake effort. Only at slow speeds and if I am pressing the brake multiple times.

Brakes did not work. It felt like I was pushing through concrete. Had to swerve to avoid collision. Had to shift to M to slow vehicle down while pushing with both feet to come to a complete stop.

I was in a line for the car wash and my brake pedal got hard and I had to apply a lot of pressure in order to get the car to stop. I was able to get out of line and got back on the road and the car was breaking fine but as soon as I got in traffic and was at a slower speed the pedal would vibrate and again the pedal got hard and was difficult to stop. I made it back to my work which has a hill pulling in, going down the hill as I pressed the brake pedal it got hard and did the vibrating thing again. I had my 2015 Chevy Tahoe towed to a dealer where im currently awaiting a diagnostic.

I decided to take a day trip up to lake Tahoe- from folsom California. It's about 88 miles away. We made it to the top of the summit and on the way down my brakes stopped working. It was as hard as rock. I couldn't push down on the brake pedal at all!! it was so scary. As the people in front of me would brake I had to use my parking brake to slow is down. My only option was to crash into the person in front of me to stop us or use the guard rail and possibly go over the side of a cliff!! my car was loaded with 5 children and 2 adults. We were all terrified. I had no indication as the driver that anything was wrong with my brakes until that moment. There weren't any lights or warnings that something wasn't working properly. My hopes is to report this and not let it happen to anyone else.

When reversing my brakes stall to work. My truck will it stop and have a almost crashed. Moving forward thru a drive thru the truck doesn't stop either. Consumer stated when reversing, brakes stall to work and consumer almost got in a car accident. Consumer felt vehicle started failing when they took it in for a recall on the antilock brakes. Vehicle no longer under warranty, vehicle cannot be checked without paying upfront. In moving up slowly through the drive thru behind cars, the brakes seem to fail when consumer steps on the brakes and almost hits the cars in the rear bumper.

Unable to brake. While attempting to slow down my brakes are making my vehicle unable to stop properly. Took my Tahoe to Chevy dealership and they were able to fix is. This issue has been going on since then end of last year. So I?ve been very limited to being able to drive. On April 9th I went to do a curbside grocery pick up with my 1 year old and 3 year old while leaving the grocery store my brakes went out. I was able to pump my pedals turned hard making it U able to brake I forced my leg to push down enough to put it on park and turn my Tahoe off. I waited 10 min to attempt to leave to the grocery store and it happened again. I called my husband for help he arrived changed out the car seats and attempted to drive him slow. As we were arriving back home the brakes went out again inside the garage at our home. Tahoe is at the dealership getting the brakes fix so I hope everything is back to normal after it being fix.

I have a 2015 Tahoe that looses break pressure at idle RPM in drive, once you raise the rpms the brake pressure will come back. We have almost hit multiple vehicles when trying to stop in a parking spot or in line at drive thru's. the problem is the brake vacuum pump is failing and I will be purchasing a new one and replacing it, I have been quoted upwards of $1000 for parts and labor for this faulty part.

- Sumter, SC, USA

In a drive thru, pressed brake down and the pedal was rock hard. The Tahoe didn't stop for an extra 3', which almost caused me to run into a chik fil a worker! he walked to my window mad, and I told him the brakes aren't working and to move the cones so I could get out of the drive thru. He did. I pumped the brake peddle and they worked enough for me to limp it to a mechanic right near there. He diagnosed a vacuum pump and charged my employer, lbb associates Inc in columbia md $524 to repair
