2020 Chevrolet Equinox electrical 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.

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.

My car is a 2020 Chevy Equinox with only 31852 miles. While driving today, all of a sudden the car started shuddering badly and stalled in the middle of the highway. Talk about a very scary situation. I pushed the car to the side of the road, and had it towed to a local shop. They found that the Fuel Pump Control Module had failed (P129F code). Upon doing some research, I found out that the 2021 Equinox had recalls issued for this same exact issue. I also found that the 2020 and 2021 Equinox both used the same part number Fuel Pump Control Module (13565638). Because of this, the recall should be extended to the 2020 Chevy Equinox so that owners pay get the major possible safety issue fixed. Luckily, I did not get into an accident when this occured and honestly Chevrolet should be reimbursing me for the repair as this should have included in the safety recall for 2021 Equinox using the same part. I appreciate your attention to this matter and look forward to hopefully seeing the right thing done here.

The sunroof opens and closes without driver input. It initially occurred at startup but now also while driving (safety/security risk) . The sunroof switch has currently been unresponsive since 2025 . The issue is intermittent and has occurred multiple times. I have a pending diagnostic appointment and an open chevrolet customer assistance case. **My 2020 Equinox has approximately 55,000 - 60,000 miles on it and I'm also not certain if I have any warranty left that will cover the cost for this issue. Thank you in advance for your assistance with this matter.

The contact stated that water was leaking into the cabin of the vehicle from the moon roof, and the rear wheel well was filled with water, and there was water moving around inside the vehicle, and the floor mats were extremely wet. Due to water entering the vehicle, the moon roof and the radio were inoperable. The contact stated that the check engine and TPMS warning lights were illuminated.

Infotainment center is not operable. Had a diagnostic test completed by certified dealership and it is found that the infotainment center and radio is not operable. Contacted General motors corporate office. $47 was offered to go towards the $950 to fix it It. They did not offer any reimbursement for the $204 paid out of pocket for diagnostics fee that I they advised me to get after filing complaint. Due to the malfunction of the infotainment center and radio other safety issues have stopped working. Such as the onstar safety feature, the phone In case of emergency, the turn signals and also the safety features on the rear and side view mirrors, car length warning, and back up camera. Was advised from the dealership that all of these functions have ceased working due to the failure of the infotainment center and the radio. Unable to hear any warnings. Made a complaint with Ohio Attorney General's office and General motors' response was only to provide me 5%, which is the $47 towards the dealership invoice. There reason was that due to the mileage they cannot assist further than that. Its not about entertainment of the radio. I feel this is a safety hazard on so many levels, and it is not caused by simple wear and tear or any fault of the driver. This is a safety issue that I want addressed. This should not be a financial burden that the consumer should carry by themselves.
