When braking and vehicle is slowing to a stop engine speeds up just before stopping and vehicle surges forward necessitating increased pressure on brake pedal. Happens every time vehicle is coming to a stop. Extremely disconcerting proceeding down a steep hill.

Brake peddle pushed back at me when trying to stop. Truck failed to slow down resulting in an accident. * (recall related incident)

- Phoenix, AZ, USA

Vehicle was in for a recall 1 week prior to recalibrate a possible error in the vacuum assist pump to brake system. This week, stopped at a stop sign on a highway, posted speed 45 and the brake disengaged and vehicle lurched forward. Called dealer, service tech says known issue, GM has issued an extended warranty to this model to repair/replace the part known to be faulty. Tech said GM should have mailed a letter saying that if, and only if the brakes failed or became hard to press, bring vehicle in. If there had been a pedestrian or vehicle close, I would have hit them. Bringing vehicle in after the fact would be too late. My vehicle qualified for the free repair so it is being repaired now.

2017 chev. Silverado 1500 ltz.. 21,240K miles.. I pulled into my church parking lot. And at low speed, I pulled forward stopped and started backing in to the space, I then pulled forward to straighten out and when I went to stop this time the pedal was hard. I was barley rolling and had both feet pushing on the pedal and stopped just in time to not hit a parked car. Then I backed into the space and again a hard pedal with virtually no brakes.

I was towing my travel trailer and the brakes failed, I totaled the camper in front of me.the notification letter from GM said even in the hard pedal situation the brakes are still in safety specs, not with a 7,000 lb trailer behind the truck.I feel GM should cover the costs of damage and update the latest notification letter to include letting the people who tow know they aren't going to stop in time. Also GM pulled the data from my truck, the airbags did not deploy, and didn't inspect the vacuum pump or the hood, bumper, grill or fenders all were thrown away. The investigator that pulled the data said it was incomplete yet GM says it's not their problem there were no codes present at the time of the accident.

Power brake failure pedal is difficult to push takes longer to stop vehicle brake pedal seems higher have to break with 2 feet

Going from 40 to 5mph breaks feel like is locking for couple of second and back to normal, any speed before stops truck has a little hesitation before breaking.

Manufacturer recall numbern192268490 NHTSA recall number19V645 on August 14, 2014, I was driving the 2017 Chevy Silverado 4X4 work truck on a rural state route in holmes county, Ohio. I had pulled off on the side of the road to pick up my traffic counting equipment. Once I was finished, I pulled into a driveway to turn around. I began to back out of the drive when the brake pedal went rock hard, I lost all pedal and had no brakes. I hit the guardrail that was directly behind me when I couldn't stop. No damage to the guardrail, but plenty of damage to my truck. Obviously, I didn't think this was right so the very next day I took the truck to progressive Chevrolet. After techs had a chance to look over the vehicle, they said the vacuum pump was defective and it was replaced at no cost to me. That's all well and good, but had the vacuum pump not failed, I would not have hit the guardrail.

I was parking my travel trailer on a camp site and readjusting. I pulled ahead down a slight incline and the brake pedal went to the floor in the truck. I pushed the pedal as hard as I could and stopped just before hitting another camper. Put the truck in park and tried the brakes again and the pedal pressure was back. I was then able to finish adjusting and it did not have the brake issue again. It was very scary with kids around etc.

Fuel injector or fuel pump does not work properly. On two (2) different occasions, months apart, my engine has lost power and the vehicle stalled. Both times at low speeds 10 - 15 mph and low rpms. This has nearly caused me to crash into one vehicle and for another to almost hit me from behind as my car died while making a right hand turn off a busy road. I have had the vehicle towed in twice, but the dealership and GM both say unless they can duplicate the issue they will not fix or replace anything. This vehicle is unsafe and needs to be recalled/reviewed. On top of this, they had to replace the vacuum pump for the brakes and do a software patch update because the backup camera was dangerously bright, especially at night. The camera issue took 2 visits to 2 different dealerships to get resolved. GM is playing the numbers game of hoping for a fine instead of paying to replace any parts. Especially since they are dealing with a pr battle about making cars outside of the usa. They took the bailout money and screwed americans.

I was in an accident on Thursday, August 22 where I slammed into the back of another vehicle on the road. I had at least 40 feet to stop and I literally stood on teh brakes and truck barely slowed down and before colliding with the other vehicle. I received a letter from GM a few months ago saying the brake assist pump may be faulty and that I could get it replaced even though if it were to fail the truck would still brake within "standard". I didnt think anything of it since it wasn't described as an emergency and I thought I would have ti taken care of the next time I took the truck in for service. My wife had commented on my brakes feeling spongy. After the wreck I was so disturbed by how poorly the truck responded to forcibly depressing the brakes pedal that I started researching and I found where NHTSA was investigating this very issue in the 2014-16 Silverado and I feel strongly that my issue should be included in this investigation. The truck should have stopped and I think a recall should be issued. The brakes do no operate within "standard" when the brake assist pump stops working.

At low engine RPM the brake force becomes extremely excessive. While backing down a long boat ramp last week this occurred and my wife could not press hard enough to stop the vehicle resulting in a collision to avoid the vehicle going into the water. I contacted Chevrolet and was told there was no recall on this vehicle.

- Onalaska, WI, USA

The vehicle in motion, at low speeds (under 10 mph), the brakes fail to slow or stop the vehicle until the brake pedal is fully depressed which unexpectedly requires more effort than braking under normal conditions. Even with the pedal fully depressed, it still does not stop the vehicle within the expected stopping range.

- Wheeling, WV, USA

Backing up my truck, at slow speed down a boat ramp, my brake pedal authority went to zero. I had no brakes during backing my boat in gulf of Mexico. I had to stand on pedal with all of my weight just to slow it long enough so I could put on parking brake. I called dealer to inquire if this was a problem, and they said I had to wait two weeks to even get it in there to look at it. Unacceptable. Loss of braking can kill occupants in these vehicles. In my case, I would have been under water and possibly drowned.

- Carrollton, GA, USA

No brakes at low speed and a hard pedal. Possibly vacuum pump failure.
