2020 Chevrolet Equinox engine 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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

A large work pickup truck pulled out in front of our vehicle and into the oncoming lane. The larger pickup truck's driver miscalculated their turn by turning too widely, side-swiping a smaller pickup truck, ricocheting off of the smaller pickup, and lastly, impacting us on the front drivers-side wheel offset.(front-left wheel offset) Our vehicle's front axle and wheels are now inclined to the right. Only the front two airbags were deployed, even though the impact was distributed slightly to the driver's door.

"Brake vacuum pump seized and shattered, sending metal debris into engine via camshaft. Vehicle lost power and would not restart – towed to dealer. Dealer found metal debris in oil fill (photo available) and quoted $2,101 for camshaft/vacuum pump and $9,480 for engine assembly – total $12,493.83. This is identical failure to class action Thieme et al v. GM for 2018-2022 Equinox 1.5L. Safety risk – loss of power brake assist and sudden stall. RO 449922 Dave White Chevrolet Sylvania OH since 10/2/26. Known defect not under recall."

I've spent $1000 on repairs to my turbo and now have to replace the whole thing. While looking online I've seen many people are having the same issue with the 2020 model. Almost every car has to replace the turbo between 60,000-80,000 miles which seems ridiculous.

The contact owns a 2020 Chevrolet Equinox. The contact stated that the vehicle failed to start, but initially the vehicle restarted. The contact was able to drive to the residence, but the vehicle failed to restart. An independent mechanic arrived at the residence and identified a failure with the fuel pump module, Part Number: 13565338, as the cause of the failure. General Motors was contacted by phone and informed that the vehicle was not under recall. The failure mileage was approximately 51,000

Vehicle began sputtering suddenly while driving 40mph. "Reduced Engine Power" warning appeared on dash. While trying to limp it home, the vehicle died in the middle of a turning lane. Pushed vehicle to the side of the road and had it towed to a shop. Their notes attached below. Technician Notes: Customer concern verified with DTCs P0014 (Exhaust Camshaft Position System Performance) and P0017 (Exhaust Camshaft Position Not Plausible). Upon removing the exhaust cam position sensor, metal buildup was found. The vacuum pump failed, breaking the keyed driveshaft on the cam and causing the metal buildup. Recommendation: Replace the vacuum pump and exhaust camshaft with timing chains, or consider replacing the engine. Same catastrophic failure as many others have reported due to the vacuum pump seizing up. Metal shavings throughout motor now, likely ruining the whole motor.

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.
