2020 Chevrolet Equinox: engine failure

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)

My son was driving the car the Service Brake Assist message popped up on the screen, and the brake pedal went stiff. He was coming to a red light and had to swerve to the right to avoid hitting the cars in front of him as he had no brakes at this point. We had the vehicle towed to our house, had the vehicle looked at by our mechanic. The Diagnosis was the brake vacuum pump, part number #12684050 exploded. It is available for inspection, at this point we don't know if the metal pieces have fallen into the engine compartments and we would rather not replace the engine as well. We had contacted the Local Chevy Service dept. who said we can pay $1500.00 to for them to take apart the top of the engine to look for broken pieces, but the best option is to trade it in as soon as possible.

My breaks stopped working while I was driving, they became hard to press and unable to function. The vacuum pump attached to the engine failed. The vacuum has broken pieces that are now inside of the engine. No warning indicator lights appeared before the incident. As far as I'm aware other similar models are having the same issue but my vin was not included in the recall.

While driving on the freeway at 75 mph my vacuum pump seized and shattered, causing me to loose all breaking power, damaging my engine beyond repair and endangering my life and numerous other drivers on the road. There is a current recall on the particular year, make and model for this issue but my VIN is not included so the dealership refuses to fix the issue.

Engine loss of power while on highway. When tried to excelerate engine sputtered, going up small incline it would not exceed 50mph. Took to auto shop and spark plug tip was broke and error for cylinder #1. They said take to dealer. Took to dealer and they said engine failed. Cyclinder #1 no combustion. Vehicle had 87,000 miles. Engine had to be replaced. $13,000. GM assist covered some but I paid $9072 to replace engine. Vehicle at approx 25000 miles had same issue. I took to dealer and they said a spark plug was cracked and had to replace. I took my vehicle in every 7k miles for oil change and inspection to local Conrad’s total car care. I was originally quoted verbally $9900 for engine repair. I called GM to file a complaint and they said engine “GM cost assist” program called me. When they got involved they offered $4100 towards repairs and dealer - Serpentini Westlake, oh increased their quote to $13k so I still pair $9072. Dealer got an extra $3k for me calling GM to complain and I “saved” or got $800 benefit from GM cost assist. What a scam.dealer refused to give me paperwork showing the details of repairs or breakdown of cost. I received a receipt that stated engine replacement $9072. They wanted me to sign the receipt but would not let me read or view any of the attached paperwork. I refused to sign the receipt and they reminded how much of a favor they did for me by giving me a loaner for approx 10 days while replacing my engine. They additionally said they aren’t required to provide me with any details regarding the GM cost assist or pricing.
