I was returning home from shopping. As I approached a stop sign, I applied the brakes and the brake pedal went completely to the floor: Fortunately, I was able to stop before entering the intersection. I had the vehicle towed to a nearby Buick dealer to determine the cause of the brake failure. I was told the left front brake line had a hole in it causing total loss of brake fluid - cause unknown. There were no warning lamps or other symptoms of the problem prior to the brake failure. The brake line was replaced by the dealer at significant cost to me.

Driver front brake hose burst, mechanic placed back in packaging for me to keep for inspection. Fortunately it busted coming to a stop for traffic light while already slowing, then could slowly drive off roadway into a parking lot, brake pedal went to the floor due to loss of fluid and could have been catastrophic for my wife or other motorists. My mechanic replaced with factory GM hoses on both sides. My mechanic is a state of Maryland licensed inspection station and confirmed the failure. No prior warning, Onstar records will confirm, after the fact, of lights and warnings of brake failure.

Brakes failed while coming to a stop causing me to crash into the back of someone. Also all dash and radio and shifter lights went out and came back on at the same time brakes failed. Brake issue still not fixed by GM Buick.

Car keeps jolting forward on it-€™s. This almost caused me to slam into the back of someone-€™s car on the highway in bumper to bumper traffic. While trying to slow down the car forcefully slams forward. Other times I have been trying to accelerate from a stop and the car slams forward. When this happens everyone is thrown forward this started happening after repair at Jack Gimbalvo Buick body shop in York. Jack Giambalvo Buick dealership said they can-€™t duplicate the problem and there are no misfires. I will be calling corporate to make another complaint. I have already been in an accident in this car due to the brakes not working correctly and the whole dash malfunctioning.

The brakes went to the floor with very little stopping power. Took the car to the dealer and the left brake line failed. The dealership said they thought since there was minor damage to the left front of the car, that this was the cause of the failure. The brake line was replaced with an aftermarket part and brake lines flushed and replaced. We had another instance of brakes going to the floor with little stopping power. This time the right side brake line failed. The dealership noticed that there was no damage on the right side of the car to cause this failure. The dealership told me they sent an email to corporate and checked for a recall on the brake lines. If this car would have been on the highway when either of these failures took place, we might be having a different conversation. I have asked the dealership to find out the cost of replacing the rear brake lines. Dealership involved in repairs. Reed Buick GMC 9550 NW Prairie View Rd Kansas City MO 64153 Phone 816-436-6300

Left front brake hose failure.

- Eugene, OR, USA

Brakes did not engage when my husband pressed on them while he was driving. Brakes when straight to the floor. He noticed brake fluid on the ground and when he filled it back up and pressed on the brakes the fluid spewed out of the brake line. His safety and the safety of others was impacted because he was in traffic and a car started to slow and our Envisions brakes were not working. He had to swerve around multiple cars and go through a traffic light to avoid causing a wreck. This just happened on 7/31 so it has not ben reported but will be going to the dealership tomorrow on 8/1/2022. We did not notice any messages or warning lights on the dash. This appears to be an issue based on the other NHTSA report number 11398881,11396874,11467669,11465728,11454501 and 11406327

The brake fluid pooled on the floor in the garage. I'm not sure how long it may have leaked out the the brakes seemed mushy the last couple of trips to the store. The indicator lights said I need to service brakes. When I put more brake fluid in, it came right out. There was a split on the right front brake hose, in the rubber section just before the junction. See attached picture.

We own a 2017 Buick Envision with approximately 42,000 miles on it. While on her way home from work, my wife experienced brake failure that almost caused her to be in an accident. I checked the fluid and the brake fluid level was low. I added fluid and it leaked out as soon as the brake pedal was depressed, which to me points to a failed brake line.

Almost crashed my vehicle on highway. When to tap my brakes and brake assist came on then my brakes completely stopped working all together. Even when I attempted to push my brake pedal down it was hard as a rock barely made it into the shoulder with my hazards on. Attempted to pump the pedal nothing - shut the vehicle off and let it sit for 5 minutes to restart still no brakes or ability to stop vehicle. Scariest thing to happen. Have to get vehicle towed

Twice in the last month, I have been driving in motion less than 5 mph, and the car accelerated by itself. I had to slam on the brakes to stop it. The tires screeched. Very scary as it accelerated fast, lurching forward. Both times in a cat lot.

Brakes failed. Brake fluid leak out of a split brake line. I was driving car for multiple stops. No problems. Came to a stop light push down on brake. Found pressure and then it release and the pedal went straight to the floor. Added brake fluid. It immediately leaked out. Investigation found a split in the brake line.

Was going down my driveway (which is on a steep hill) and brakes totally gave out. Luckily no one was on the road and I was able to get the vehicles to a mechanic. Mechanic found a small pin hole in right front brake hose which he found unusual. All brake fluid leaded out. Near the hole was a spring that wraps around the rubber brake line. It was pretty obvious the placement of the spring caused the damage. The brake line developed a hole in it where the end of spring touches rubber brake line. The nigh before I was on the interstate. This could have been devastating.

On at least 5 different occasions the dash board lights and infotainment system have went completely black this is at varying speeds from 25 miles to 60 miles and even sitting at a stop light this has happened. When it does happen its only for couple seconds. This has also happen twice while my teenage son was driving and scared him quite a bit. Most recently while at a stop light I let my foot of the brake and push gas I get a message saying park brake released the doors unlock then lock. I try to move the steering wheel but its hard like it's locked I then get message saying power steering has been reduced drive carefully. Then a following message saying all wheel drive has been turned off. This has happened about 7 or 8 times randomly after coming to a stop for a red light in which light turns green I try to proceed than all this messages and wheel tightens and car feels like it stalls for a second.
