I was driving down the road and my engine stopped. It stopped so suddenly that I did not have time to get out of the road and my safety was put at risk. When I took it to a certified Chevrolet dealership, they told me that the vacuum pump failure caused extensive damage to the motor and I needed to have my entire motor replaced. When I asked them what I could have done to prevent such catastrophic failure, they stated that there was nothing to prevent it. I did not have any warning on my dash at the time of the incident. This was at least the 2nd vacuum pump failure on this vehicle since I've owned it. I got it replaced at a certified Chevrolet dealership in 05/2022 when my brakes went out. In 05/22, the brakes went out but I was in a driveway and I did not feel my safety was a concern at that time. Now it's not even been 3 years and the vacuum pump failure risked my safety and caused catastrophic damage to engine to be replaced.

I was driving on the freeway way and during rush hour at 65 miles per hour the brakes completely stoppped working the peddle wouldn-??t press I had to swerve to avoid an accident and slowly exited the freeway when it was safe to coast over from the number one lane to the exit. The vacuum pump failed which exploded inside my engine which in turn makes the engine stop functioning and destroys the whole engine with out warning

The vehicle vacuum system and the power brake booster has caused the vehicle brake to fail in motion the second incident was almost fatal

- Acworth, GA, USA

The brake vacuum booster failed, causing the brake assist system to malfunction. Yes, the component is available for inspection upon request. While merging onto the highway, the brake pedal became extremely tight, making it difficult to slow down or stop, creating a hazardous situation. Yes, the issue was confirmed by a service center, and the brake vacuum booster is being repaired. No, the vehicle and component have not been inspected by these parties, but the service center is addressing the repair. Yes, a -??Service Brake Assist-?? warning appeared immediately before the brake pedal tightened. Afterward, the check engine light came on.

I was driving down a driveway with a slight incline. I pressed the brakes and they were very hard to press and vehicle would not stop until I collided with a wall. This is the fourth time that this has happened in the last two years. Each time it has been the brake booster vacuum pump which my mechanics have said is a common problem with this vehicle. One of the previous times my daughter was driving on the highway when the brakes failed and she ended up in a ditch off the shoulder. This is very dangerous and someone is going to get killed if it hasn't happened already.

My wife started noticing issues with our 2019 Equinox. We got several error mesaages: service brakes, service sylteering, enigine light and abs. I did some digging online and found similar issues with other Equinox owners. The fix is to replace the battery. We did and after leaving the shop the car won't move. It will go into differnt gears but wont move and is currently at home in our driveway.

originally system warning message to service brake system. had system checked by mechanic. nothing found. after a few weeks as i was merging on a highway i felt my engine start to stall. I immediately tried to make my way to the side of highway. brakes were very hard to press and car stalled with engine light immuninating, and no power steering. code P0017. engine will crank and sputter but will not start also has blowby present. cam and crankshaft sensors/actuator solenoids were replaced, then the vacuum pump cover was opened and found broken parts inside. upon removal of pump it was found broken. suspect broken parts are blocking crankshaft or either of the cams to not be able to rotate properly. this issue possibly has cause timing chain issues as well. parts in the vacuum caused it to seize. exhaust cam continued to spin shattering the end connected on the pump. I have done research and found that others have had the same thing occur with the warning for brake system and then weeks later the brakes do not work, which is due to the pump providing pressure for the brake boost system.

I was traveling at expressway speeds (70 mph) when traffic in front of me hit the brakes quickly to avoid an object in the road. At this time, I hit my brakes relatively hard and fast in what I would describe as a panic brake. I avoided incident here. About a mile further up the road, traffic in front of me hit the brakes once again. At this time, I also hit my brakes, but I could not. My brake pedal was hard as a rock, and it would push down only about 2 or 3 inches with little to no effect. I was afraid I might break the pedal arm. I was able to maintain my lane until about 40 mph at which time I was forced to hit the shoulder to avoid colliding with the cars in front of me which were now stopped. I pressed the brake pedal hard and coasted along the shoulder of the expressway for about 40 or 50 yards, rolling past the stopped traffic. A few minutes after my car came to a complete stop, the information panel on my dashboard read "service brake assist". My car was towed to a GM dealership local to where I came to a stop. The documentation from the dealership, as well as what I was verbally told, indicates that there was an internal failure of the vacuum pump. According to the service manager, there was nothing I could have done to prevent this. Obviously, I was extremely lucky. If this would have happened in two-lane city traffic, or approaching a stop light I would have been forced to veer into oncoming traffic or simply barrel into those in front of me. I know this, because for the last month, as I'm driving, I constantly analyze what would happen if my brakes were to go out like that at various points along my drive. Often times, my only option would be to brace for a major accident or land my car in the front yard of a business. This catastrophic failure could have easily killed me, and/or other drivers on the road. Other people will not be so lucky, and I know this. For that reason, it's time for NHTSA to finally take action on this matter.

I was driving on the highway in traffic when the brake pedal became hard as a rock I was unable to stop causing a major safety concern for myself and baby. Turns out the vacuum pump was faulty causing my brakes to fail.

I have 2019 chevy equinox I purchase the car last year with 61 miles. On March 12, 2024 I was 5 minutes away from home after driving an hour from work, try to stop at the stop sign the car didn't stop I tried several time to stop finally put it in neutral for the car to slow down to be able to pull over to stop thank God I wasn't hurt. After taking it to the dealership to get look at now the telling me my camshaft broke to pieces which will cost with the vacuum booster $24000 with only 70 miles.

Our 2019 Chevrolet Equinox had a sudden Brake Vacuum Pump failure causing loss of braking power by about 80%. The only reason we did not have an accident is it was early morning and there was no traffic when we exited the highway. I was not happy to realize that GM has no recall on this. They apparently knew this was a problem and in more recent years have changed the design. The other flaw is this pump is attached to the wall of the engine and shrapnel can fall into the engine compartment and that debris could lead to total engine failure if it travels to the combustion area. This is not only dangerous but financially ruining.

Mechanic said it is this exactly like the other cars but yet my cars vin does not show recall for this [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving 70mph on the interstate with moderate traffic. Came up on a slow down and tried to brake but my brake pedal would not move. It took both feet pushing as hard as I could to stop my car. Luckily I didn't hit anyone. Had to trailer the car home. Had the code read at O'Reilly auto parts and it is the failure of the brake booster vacuum pump. My car has a little less than 70,000 miles on it. There were no warning lights, NO NOTHING up to this point. Luckily I leave plenty of room between me and other cars or this could have been a really bad turnout.

While driving my 2019 Chevy Equinox it was acting to me to have a flat tire shaking weirdly in what felt like the front right tire. I was going around 72 mph down the freeway slowed to exit to the nearest station no issues there my speed was around 37 mph exiting off the freeway and SUDDENLY THE BREAK PEDAL WAS TO HARD TO PRESS I FOUND MYSELF WITH NO BREAKS the break pedal was EXTENDED OR" It wouldn-??t press down at all and although I tried to pump them, I didn-??t want to break anything and it felt like if I pushed down it would break something! So I wheeled it into the gas station and put it in park to stop. I called right away to the dealership I bought it at and had it towed from the station! I was lucky! I KNOW I WAS LUCKY! I MIGHT NOT HAVE BEEN!! This came without warning other than thinking I had a flat from the shaking! There was no light or other symptoms to alert me! IMAGINE SUDDENLY THE CAR IS SHAKING AND YOU HAVE NO BREAKS!?! THE CAUSE I WAS TOLD IS A FAULTY BOOSTER! IF YOU CANT GUARANTEE THE BREAKS WHY SELL THE CAR! ITS A VITAL ASPECT OF SAFETY! NOW IM TERRIFIED! THIS IS NOT OKAY! ALL I GET IS EXCUSES AND RUNAROUNDS ABOUT IT! BE AWARE THESE CARS HAVE ISSUES! HOW CAN A CONSUMER FEEL SAFE DRIVING A VEHICLE NOT KNOWING IF THE BREAKS WILL WORK OR NOT"! The shaking was my warning I say looking back but NOT AN ACCEPTABLE ONE! I think it-??s what SAVED MY LIFE AND THOSE OF MY CHILDREN! Only the shaking!!!!!!!!!!!!! NOT OKAY GMC NOT AT ALL!!!!!

Vacuum pump failure resulted in greatly reduced braking ability

- Scandia, MN, USA

Failure of Brake Vacuum Pump. Oil intake screen of brake vacuum pump became clogged. (Have been diligent in regular oil changes) clogged intake caused pump to not receive lubrication, which resulting in it seizing. Pump is mechanically driven by exhaust cam shaft. Failure caused brakes to become almost impossible to engage. Even worse. The metal parts that were connected to the cam shaft were shattered, and the pieces ended up directly in the crankcase. This seems like a dangerous and potentially very expensive design flaw Pieces in picture had to be removed from crankcase..
