2020 Chevrolet Equinox brakes problems

Filed Nov 5, 2026 · Brakes, Electrical · IN

2020 Chevrolet Equinox, approximately 84,453 miles. On XXX, the vehicle experienced a catastrophic braking/mechanical failure. The brake system lost power assist. Following physical inspection, the insurance adjuster documented that an internal brake booster/vacuum-related failure caused loss of brakes and excessive vacuum on the engine, resulting in internal engine failure requiring engine replacement. I subsequently learned of pending federal litigation, [XXX] et al. v. General Motors LLC, Case No. XXX concerning an alleged brake vacuum-pump system defect in 2018-2022 Chevrolet Equinox vehicles. I am reporting my vehicle because the failure involved loss of braking assistance and catastrophic engine damage and appears potentially consistent with the failure pattern alleged for these vehicles.

There were no warning lights prior. We were driving on the highway and the brake pedal all of a sudden became hard as a rock, and we could barely stop the car. Stoping distance was extremely long and dangerous, we were very lucky there was no one in front of us and that we were almost the the exit we needed to be at. Managed to slowly pull the car into a lot and arrnage for a tow to the nearest Chevrolet dealer (Open Road Chevrolet, Union NJ). They inspected it and said the vacuum pump was missing. Also said the notify the customer that tehre may be damage to the camshaft but they did not elaborate and they replaced the vacuum pump and verified their work and said no further repairs required at this time. Crazy dangerous situation to be in. Nothing warned us aboutt he issue at all. Just happened and we were very lucky.

Vacuum pump, I was driving 75mph and needed to slow down due to traffic and my break pedal was hard and wouldn’t stop me, I almost hit a car in front of me. I also had my children with me. No the problem hasn’t been inspected, I bought the part to repair it myself. There was no fair warning. I ALMOST wrecked with my children in the car! I was over a hour and half from my house.

The contact owns a 2020 Chevrolet Equinox. The contact stated that while driving approximately 20 - 25 MPH and depressing the brake pedal, the brakes locked up. The contact turned into a nearby parking lot and coasted to a stop and shifted into park(P). The contact waited a while for a co-worker, and the co-worker drove the vehicle to the residence. A certified mechanic arrived and inspected the vehicle. The mechanic informed the contact that the brake booster had failed and there was a recall for the failure. The manufacturer was informed of the issue and confirmed that the VIN was not included in the recall. The manufacturer referred the contact to the federal safety agency Hotline to report the failure.

While operating my vehicle, I experienced a sudden, catastrophic failure of the power-assisted braking system. The brake pedal completely lost hydraulic pressure, plunging effortlessly all the way to the floorboard. The vehicle failed to respond to normal foot-pedal application. Emergency stopping power was only achieved by pushing the pedal into the absolute floorboard, which engaged an emergency mechanical override and forced the Anti-lock Braking System (ABS) pump into a violent stutter/pulsation to halt the vehicle. No dashboard warning lights, diagnostic trouble codes (DTCs), or fluid level sensors illuminated prior to or during the braking failure. A certified automotive repair facility diagnosed the root cause as a total internal seizure and mechanical failure of the engine-driven brake booster vacuum pump. Because the vacuum pump is driven directly by the engine, its sudden lockup sheared and severely damaged the drive slots on the exhaust camshaft, necessitating an intensive engine teardown, camshaft replacement, and secondary component repair totaling $2,390. This design poses an extreme, life-threatening safety risk. The total loss of braking assist occurs without warning, and the mechanical failure simultaneously compromises internal engine timing components while moving at speed.

The contact owns a 2020 Chevrolet Equinox. The contact stated that while driving 80 MPH, the message “Service Brake Assist” warning light illuminated twice. The contact stated that while attempting to depress the brake pedal, the vehicle failed to respond as needed, causing the contact to engage the parking brake and manually shift the gear shifter to a lower gear to get the vehicle to come to a complete stop. A dealer was contacted. The contact stated that the check engine warning light was illuminated. The contact stated that the failure had occurred twice. The vehicle was taken to the dealer, where it was diagnosed and determined that the brake booster pump needed to be replaced. The brake booster pump was replaced, and the vehicle was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 94,000.

While driving, my 2020 Chevrolet Equinox suddenly lost power and shut off without warning while I was pulling into traffic. The vehicle would buzz not crank afterward but would not restart. This created a safety hazard because the unexpected engine shutdown occurred while the vehicle was in motion. This is the second brake vacuum pump failure I have experienced with this vehicle. In 2022, the brake vacuum pump failed and was found shattered internally. At that time, the engine continued running, and the pump was replaced. During this most recent incident, the brake vacuum pump failed again, and the internal end of the pump broke apart. I replaced the vacuum pump and removed the broken pieces I could access, but the vehicle remains in a crank/no-start condition. The vehicle has not yet been inspected by a dealership or independent repair facility. However, after seeing the shattered pump components, a couple of mechanics I know expressed concern that the broken pieces may have affected the engine timing. That has not been confirmed. The failed pump and replacement parts are available for inspection.
