In May 2026 while driving home from her job in downtown St. Louis, my daughter was driving my equinox. While traveling on the highway at the speed limit of 55 miles an hour her brakes failed and she came within a few feet of rear ending a full gas tanker truck. She was able to maneuver to the shoulder of the highway and avoid an accident. After a few moments of the engine, idling the engine completely stopped working and shut down. After having the car towed to my local mechanic at a Midas shop, they began the diagnosis. I began similar research online to find cases of similar things happening. What was diagnosed is that the vacuum pump on the brake line was faulty and broke. Pieces of this pump made their way into my engine and ruined two of the cylinders in my engine. The car is now not drivable and needs a replacement engine. Chevy knew about this faulty, vacuum pump part and they did issue recalls on other vehicles using the same part. They have also issued technical bulletins to their technicians for a diagnosing this failed vacuum pump. I have tried to contact Chevy and they have offered me no assistance. I know a class action suit has been filed for this very same issue. Chevy is aware of this issue. Chevy‘s choice to use a part they knew was faulty. Almost led to the death of my daughter.

I was driving and the suv moved forward with a jump like that scared myself, this happened several times. I just had my oil changed at the dealership of which I been working with for 20 years. A few of my sensors went out at the same time. On June 19-26 my suv refused to change gears. I pulled over and tried again. Made it home and towed it to the dealership June 22. I noticed that there are two car factories having the same issue and had a repull, so I thought that my suv would be included. Well, Not, my suv is from another factory that has no recalls. Dealership wasn’t working with me until July 17th after I reported them to BBB-and General Consumer. I met with the dealership July 24, and offered me 11600.00 just for fixing the transmission. I can’t get an answer if anyone else from factory number three has had the same problem as myself and the other two factories. My SUV is seven years and 81,000. Dealership offered to buy my car for 500.00 as is.. and after the transmission only 1000.00. This is crazy!!! I bought new and they are the only dealership that has worked on my car. I only put premium gas. Why does it matter what factory if they all have the same problems. Thank you..

I was driving on the freeway at 64 MPH when my Brake Assist alert appeared on my dashboard. At that time I lost assisted braking capability. I was able to steer and stop my vehicle on the shoulder of the freeway. I turned the car off and was unable to start the car again. The car was towed to the dealership where they stated “ Hi Erika, the vacuum pump on your engine seized and broke the shaft and damaged the tone ring on the camshaft, there are quite a bit of metal pieced in the engine due that that failure. Unfortunately, the solution is a remanufactured engine at the cost of $11500.00 parts and labor plus tax. How would you like to proceed?” Currently we are opting to not replace the motor. It is apparent that this is a common issue with this year/make/model of vehicle.

Vacuum pump failed: On May 28th, 2025 the brake pedal on our 2019 Chevrolet Equinox became very hard along with check engine light, a "Reduced Power" notification, and "Brake Assist Failure" notification. After a mechanic inspected the engine, he found that the vacuum pump had shattered. The mechanic replaced the pump with an OEM replacement from GM. On May 11th, 2026 the same exact issue happened again. 1. The vehicle and/or part is available for inspection. 2. Anyone driving or riding in the vehicle is at risk due to the difficulty of braking. 3. The vehicle/component has not been inspected by the manufacturer since the 2nd incident.

I was trying to stop at a light and the brakes wouldn't work. I almost crashed into the car in front of me but I had to step on it really hard to stop. Then the brakes were stiff and it was hard to stop. I brought it to a Chevy dealer yesterday and they said the vacuum pump exploded and pieces were in the engine, and it messed up the cam shaft. This is 5l worth of damage. When I looked it up online it seems this has been an issue with GM cars and the equinox was left out of the recall which could have prevented this. I have 95k miles on this car and never had an issue until now. However it is not worth spending 5k on a car that is high in mileage.
