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.

I was at a stop light, the light turned green and I proceeded to lift my foot off of the break giving the vehicle a moment to autostart, I pressed the accelerator, and the car started to make a sputtering sound and tremble terribly. The vehicle's engine shut down in the middle of traffic, no warning lights appeared on my dash board. The power of the vehicle was still on. I placed the car in park, then I turned the power off. I tried to restart the vehicle this time the vehicle continued to shake and sputter but it did not move when I placed the gear in Drive. I had to be pushed put of the road by the Police and then towed to the dealer. The service engineer at the Chevy Dealership was able to start the engine and take it for a test drive, the vehicle also shut done on him but also left him with no ability to use the breaks. He was unable to stop. Thankfully no one was in front of him or behind him he was able to have the vehicle towed back to the service bay. I was told that the break vacuum pump disintegrated and went into the engine cam shaft. That caused the engine to completely shut down. I believe this is a safety issue as no sensor or engine codes ever displayed and the dealership took 2weeks to diagnose what was wrong because they were not getting any codes displayed on their diagnostic equipment. There was no way for me to know this break vacuum pump was failing to be able to proactively replace it to prevent this serious malfunction from occurring. I could have been seriously injured and cause a horrible accident as I was headed to the highway that morning. I would like to be contacted in regard to this.

2019 Equinox LT. 1.5 litre Vacuum pump clogged and exploded internally. Almost killed my wife and I when brakes failed. There appears to be TSB-??s dating as far back as 2015. Chevy has been aware of this issue yet continued to produce vehicles with this defective and dangerous design. It sounds as if piston rings are prem The pump connects to and is powered by intake cam. Dumb. Micheal Bates dealership say I-??m responsible for the parts and repairs, because is no warranty, which are about the car used repairs, all internal damage to engine.

The vacuum pump failed, which left me without power brakes while slowing down on an interstate exit ramp. There were no warnings or indications of failure in advance. The brakes were fine as I got on the interstate, then I became aware of the problem as I exited about 30 minutes later. I nearly rear-ended the car in front of me as we approached the stoplight. Without power brakes, much more force than usual was necessary to come to a stop safely. This is a very dangerous situation as elderly or physically disabled drivers may find it very challenging to apply enough force to come to a stop, especially when slowing down from 70+ MPH interstate speeds. Metal pieces broke off from the vacuum pump and caused damage to the cam shaft. While reviewing some YouTube videos on the topic, I discovered I'm not the only Equinox owner to experience this type of failure around 5x, xxx to 6x, xxx miles for the 2019 or similar model years. Here is the link to one representative video, and the comments indicate there are others who have experienced something similar... 2018 Chevy Equinox Vacuum Pump Catostrophic Failure!

There was a recall back in 2019 for this same issue the charge air cooler is still disconnecting from the throttle body. I bought this car in 2021 supposedly the issue was fixed back in 2020 after the recall was issued. The same thing is happening. When I accelerate the air hose connecting to throttle body is disconnecting from and causing the engine warning of reduced engine power to show up. This is very concerning because when driving on the freeway with my family this is happening and this could get someone killed. The fixes back in 2020 are not up to standard or the replacement parts are faulty or the repair was not completed successfully. This has been happening since last year summer

This vehicle has started to lose power was taken to firsteam Norfolk Va where purchased took for oil change and tire rotation also loss of engine power at speeds of 20-32 mph and 50-62 mph. Dealership at Norfolk Va sent to firstteam Hampton VA Chevrolet for diagnosis and came back no engine light and small misfire 3/4 sparkplugs needed changed $177. After plugs were changed still had misfire then they felt it was number 4 injector $500 but never did work. I took it to national shop for recommended injector and when plugs were pulled mechanic found no new plugs. Injector was replaced with gm part and still misfiring. Norfolk firstteam towed vehicle back to Hampton Va firstteam and they are now giving me the run around. They want a blank check to replace parts till they find the problem. Unexceptable to even ask. Service writer has been very disrespectful and hung up on national shop and myself. When asked questions regarding work done service writer would just talk over us and speak to us disrespectful and then hung up. We have requested service manager at Hampton firstteam Chevrolet contact us and we were told she would tell him later. I have contacted Aston Lewis Jr owner of all firstteam dealerships here in Va requesting help three times and still no response. We need this reported so someone can fix the misfire and power loss the dealership does not know how to fix. Car is under power train warranty. Any help would be nice.

The vehicle is operating on reduced power and shuts of almost immediately. After plugging a scan tool in and reading the codes, it said the crankshaft timing was over advanced and the sensor needed to be changed. I've changed all four sensors (both crank and cam sensors). The engine shows no codes, but when I crank it, it immediately reduces power, shuts off, then shows the same codes. After trying a few times, it says the ECM, MAP sensor, and heat sensors are bad. When I disconnect, then reconnect the battery, it only shows the crank sensor code. The check engine light goes off, but comes on again right before the engine shuts off each time. As a result, the vehicle has been sitting since 10/4/22 due to it shutting off suddenly in traffic. I've had to change the battery twice during this time due to the battery completely dying and a jump start doesn't work.

I've taken my car to the Springfield chevy dealership at 840 Baltimore Pike, Springfield, PA 19064 several time. The time the replaced mass airflow sensor had to be replaced or the oxygen sensor last year. I received a message from Onstar An issue with the emissions system in your 2019 Chevrolet Equinox has been detected. Please service your vehicle within 7 days. Which was the same message for berfore, ?Wayne the techn stated it the battery which is incorrect I informed him of the Onstar message and told him how the car would shut-off and wouldn't start. I had two battery test perform and was told the battery, starter and charging system all passed. He stated we have to change the battery as a starting point and work from there which is ridiculous. I stated if this is so why wasn't this mention in the Onstar Diagnostic Alert. My car was there for six hour and no one call I had to contact them around 4pm and they close at 4:30pm no customer service.

Winter 2021, vehicle went into reduced engine mode as I was going up a hill. There was no one behind me and I made it 100 ft to a driveway. I was able to turn around and get car home. Towed to Sonju, dealer where it was leased from. Fixed by them and returned to regular use. 06/28/22, while driving on a Hwy 53, 45 mph zone, with no notice, engine went into reduced power mode. I was almost hit due to the proximity of the car behind me and the sudden loss in power. I managed to hit my hazards, pull into middle turn lane until traffic passed. I then was able to get into a business parking lot. I shut car off. I made some phone calls. Turned car back on, all was fine. Back on the road. No call to dealer. 07/08/22, engine in reduced power mode while I was only.5 miles from my house. Made it to a turnaround point where I was able to turn vehicle off. Called dealer to make appt for service. Limped vehicle home. Vehicle towed to Sonju for fix. 07/18/22, after fixed at dealership, it was picked up. We made it 22 miles. I was in a urban part of Duluth, MN-speed limit 30, heavy traffic. As I turned to go up hill, engine again went into reduced power mode. There is no shoulder for me to go to and I'm almost hit from behind as the car jerked and slowed. I was able to pull off. Shut car off. When I started it up, it was still in reduced power mode. As it had been 30 mins, traffic had subsided, I went another mile to my work, where car would be safe to sit. Made arrangements for tow back to dealer. 07/19/22-towed to dealer after hours. When I moved it for better position for tow truck, the check engine light was on, but engine reduced power mode message never came on. 07/22/22-Per dealer, there is no explanation and thus far they can't figure it out. They continue to drive it to recreate the issue, but no end in sight of when I will get this vehicle back. 07/26/22-no word from dealer-vehicle is still there. I stopped bugging them!

The Charge Ari Cooler Duct Disconnected from the Throttle Body. When this happens my car immediately goes into lower power mode. This is a safety concern, when going 70 MPH, it will immediately drop down to 50 MPH. This sudden decrease in speed can cause other drivers to wreck into me and my family. This problem has been confirmed by a dealer. This has not been inspected directly by the manufacturer, however it was inspected by a dealer. There were no warning signs prior to failure, only a warning after the incident occurs. The check engine light comes on.
