2019 Chevrolet Equinox

Poor quality Vacuum Pump failed, resulting in debris in crack shaft assembly and preventing brake functionality. Check engine displays and error message stated "Service Brake Assist" which does not indicate a vacuum pump failure, which is misleading in troubleshooting issue. Hard brake pedal is a symptom, which would lead a repair facility or consumer to replace Brake Power Booster, which does not resolve issue, but will temporarily resolve brake pedal symptom, leading to further damage to crank shaft.

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.

The vehicle is leaking oil from in between the engine and transmission I am some bit mechanical and im sure its the rear Maine seal leaking yes the vehicle is available for inspection im taking it to H&H chevrolet [XXX] for a inspection I talked to Christian brothers repair and I told them what it was doing and they told me alot about my vehicles problem and gave me some Estimates and also said they have 2 in there shop right now needing the same repair...How was my safety or the safety of others put at risk? well me and my family went out to get a few groceries and it was -25 outside and we almost didn't make it back home because the car was not wanting to drive.if it had died we would have been stuck in dangerously cold weather.no warning lights came on I only found it was leaking when I started to smell burning oil so I looked under it and there was a small puddle of oil. this happened Monday [XXX] and the car hasn't been drivable since it sounds fine but I don't know we haven't moved it since we got it home. this is really inconvenient this vehicle is my only means of transportation to work and I never thought on a car I purchased brand new it would ever blow a rear seal I have heard many other having these problems and I still can't understand why this isn't a recall this is a very expensive problem to just be put on people financially. i hoping GM can resolve this for me.

While driving, the vehicle went into Engine Power Reduced mode, check engine light went on, and the Brake Assist notification came on. I pulled over and turned off the vehicle; vehicle would not restart. Had the vehicle towed for diagnosis; told initial codes were timing issues. Vehicle has 83,000 miles and showed no evidence of any sort of failures - no warning lights, no brake issues, no hesitation, no unusual sounds, no rough idling or driving. Dealership stated the vacuum pump failed and broke apart into the camshaft and into the engine. Official diagnosis was new vacuum system and engine replacement for a cost of $14,000.

Vehicle runs with reduced engine power. Was initially told the turbo needed cleaned, and it continued to happen. Then was told it needed to be replaced. The final result is that the tube that connects to the turbo keeps falling off. Being told there is no fix, and no recall, we just need to keep putting it back on when it pops off.

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.

The contact owns a 2019 Chevrolet Equinox. The contact stated while driving 40 MPH, the engine made an abnormal ticking sound. Additionally, the contact stated that while depressing the brake pedal, the brake pedal felt firm and failed to respond as needed. The contact stated that upon depressing the brake pedal two feet, the brake pedal travelled down as needed, causing the braking distance to be extended by 222 ft. approximately. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the vacuum pump had seized and shredded to parts inside the engine. The mechanic determined that the vacuum pump needed to be replaced. The vehicle was repaired. The contact stated that two unknown dealers and the manufacturer were notified of the failure and informed the contact that the VIN was not under recall. The failure mileage was approximately 74,000.

The same issue has occurred on my vehicle but the dealership is stating my vehicle is not covered even thought it states it has all the issues stated in this bulletin. N192271200 Charge Air Cooler Disconnect at Throttle Body. The car blows off the hose at the throttle body even after I replace the retainer clip myself. I am now having the dealership repair the hose and clip as it needs both they said. It obviously is a flaw in more vehicles than what they have disclosed. Very unfortunate they do not cover this for all owners in the same year as this series of vehicles.

Vacuum pump exploded and ended up breaking the cam shaft. Brakes wouldn't work for a minute completely seizing up in rush hour traffic. It did eventually stop. Got it to the auto shop close by and they inspected the vehicle. They stated this shouldn't have happened. Also, in their experience they have never seen someone able to drive their car with this issue. It typically locks up the engine by sending broken pieces inside and blows it. They said I was very lucky it didn't cause an accident, catch fire due to the oil, or explode the engine from the broken pieces. The techs stated they have seen this a lot in the Chevy Malibus and some in the equinox's but that they run on the same engine so that would make sense. There was no warning prior to this happening. The vehicle was inspected by the auto shop techs and report sent to me with photos of all damages.

The contact owns a 2019 Chevrolet Equinox. The contact stated that while driving at 65 MPH, the "Service Brake Assist" message briefly flashed on the instrument panel. The vehicle then independently downshifted and decelerated to 30 MPH, with the brake pedal depressed to the floorboard. The contact was unable to stop the vehicle but was able to coast the vehicle to an independent mechanic. The contact was able to turn off the vehicle after the failure; however, the mechanic was unable to diagnose the vehicle. The vehicle was then towed to a dealer where a mechanic informed the contact that the vacuum pump had failed and sent debris through the camshaft. The contact was informed that the vacuum pump, timing chain, cam shaft, and pistons all needed to be replaced. The manufacturer was notified of the failure and the contact was given a reference number. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 100,000.
