2020 Chevrolet Equinox electrical system problems

“The contact owns a 2020 Chevrolet Equinox. The contact stated that there were persistent electrical issues with both side-view mirrors independently adjusting after the vehicle was turned off. The driver was constantly manually readjusting the mirrors while operating the vehicle. The dealer performed a software reprogram, but the failure recurred the same day. The was intermittent at first but had become a constant failure. The manufacturer was notified of the failure but referred the contact back to the dealer for assistance. The failure mileage was approximately 25,000.”

“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…”

“The electrical system just stopped working it is throwing up false alerts of driving systems and brake assist, and then the air conditioning on/off button doesn’t respond defrost nothing lights up or comes on.”

“My cooling and heating sensor is reading negative 40 degrees outside but it has been 80 degrees and higher the past several weeks. This is not safe when you have children especially if they are under [XXX] old.”

“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. Sincerely, [XXX]”

“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.”
