2020 Chevrolet Equinox

My engine started running rough and, as a result of a repeating PO301 code, the car was towed to Lester Glenn of Toms River. Their diagnostic scan report (codes DTC PO301 & DTC PO303) found the engine assembly has scored cylinder walls due to failed piston rings. The entire engine had to be replaced. The odometer reading was 19,000 miles. Piston rings are designed to last 150,000 plus miles. For them to be worn enough to score a cylinder wall at 19,000 miles is a textbook definition of a manufacturing defect. Piston failure represents a serious safety defect as it could have caused a total loss of power at highway speeds. This was a safety-related manufacturing flaw, and not a maintenance issue. GM refused to pay for the repair bill in full.

While driving, the vehicle experienced an almost total loss of braking capability. The pedal was very hard to press, and when pressing with all my weight, I could slow the vehicle to a stop, but it took a great distance. There was no warning or malfunction indicator until I pulled into a parking lot a few minutes later. At that point, a "Service Brake Assist" message appeared. Had I been in traffic, going faster, or in an area with pedestrian crossings, this could have caused a possibly deadly crash. I searched online and found that there is a vacuum pump that is known to fail on this vehicle, and can cause these symptoms. Upon replacing this vacuum pump, the issue was resolved. I still have the failed vacuum pump.

The contact owns a 2020 Chevrolet Equinox. The contact stated that while driving at approximately 60 MPH, the vehicle's brakes did not depressed, it maintained the same speed the warning indicator stating service brake assist illuminated and then the check engine light illuminated. The emergency brakes were engaged in order to allow the vehicle to slow down. The vehicle was towed to the dealer where it was diagnosed with a vacuum pump for brakes failure. Additionally, metal was in the engine due to the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was

I was driving to work, when I got off the exit I stopped at Sheetz. When I got back in the car my brake pedal was stiff as a rock, and there was oil on the ground. A friend of mine does mechanic work so I called him and he said it sounds like the vacuum pump. I had the car towed to his garage, the tow costed me $400 which was very cheap considering where I was located. When I got it to the garage he confirmed that it was the vacuum pump and we removed several pieces of metal from inside the engine. I now have my car at the Chevy dealership in Chippewa PA. They told me to be $180 a diagnose it, well they just called me a little bit ago and said it's going to be another $900 to take everything apart and to truly diagnose it. I'm finding out now that GM has known about the failing vacuum pumps and they kept producing them anyways. I see there's a class action lawsuit taking place, and I am not very happy. My life was put at risk. And now I'm expected to be stuck paying this huge bill?

I am submitting this on behalf of my daughter, [XXX] . On Friday, May 8, 2026, [XXX] was traveling southbound on Highway 89A approaching [XXX] . Highway 89A is a narrow, winding two-lane canyon road with limited shoulder and significant elevation changes. While still on the canyon road, her 2020 Chevrolet Equinox suddenly lost all power, including power assist to both steering and brakes. A sudden loss of power steering and brake assist on this road presented a serious risk of loss of vehicle control. Fortunately, she was able to get the car stopped off of the roadway. However, she was then unable to place the car into Park or shut off the ignition. Multiple warning lights were illuminated across the instrument cluster. Her roadside assistance plan towed the car to the nearest repair facility, where on Monday, technicians were unable to replicate the issue. A previously stored DTC P3055 was found in the diagnostic system. This code relates to a known and documented issue with Chevrolet Equinox vehicles, for which Chevrolet has issued multiple Technical Service Bulletins, including TSB 21-NA-139, which identifies the Multifunction Power Supply Converter (GM Part #13510484) as the known culprit for this failure mode.

On Saturday, April 18, 2026, I was driving home from a neurology appointment with my two daughters, including my child with special needs. I intentionally chose not to take the expressway and instead drove a lower-speed route home for safety reasons. While traveling approximately 35 mph, the vehicle suddenly displayed an “Engine Power is Reduced” warning. As I attempted to safely maneuver through traffic and pull over, the brake pedal became extremely stiff and difficult to depress, requiring significant physical force to slow and stop the vehicle. The sudden reduction in braking assist created a serious safety hazard for my family. Had this occurred at highway speeds on the expressway, the outcome could have been catastrophic. A post-incident inspection identified failure of the vacuum pump drive assembly and related timing/variable valve timing (VVT) components. Photographs taken during disassembly document the condition of the timing chain, camshaft, VVT actuator/phaser, vacuum pump assembly, and associated components at the time of repair. Diagnostic records also documented DTC Code P1101 following the incident. The vehicle is currently undergoing further inspection and diagnostic evaluation at a certified Chevrolet dealership to validate CPO warranty coverage and determine the full extent and cause of the failure. Based on the sudden loss of engine performance and reduction in brake assist, I believe this condition represents a significant safety risk to vehicle occupants and the public.

I am reporting a vehicle fire involving a 2020 Chevrolet Equinox [XXX] ). The fire originated in the engine compartment. The official fire report lists the causes as "undetermined", with the area of origin identified under the hood. There were no prior warning lights, mechanical issues, or indications that a fire risk was present. The vehicle was being used under normal conditions and was properly maintained to my knowledge. The vehicle was declared a total loss by my insurance company. Due to the undetermined cause and engine compartment origin, I am concerned there may have been a potential mechanical or electrical defect that was not identified. I am submitting this report in case similar incidents have occurred and to support an potential investigation int vehicle safety.

The contact owns a 2020 Chevrolet Equinox. The contact stated that while driving at various speeds and attempting to accelerate from a stop, the engine started choking. The vehicle lost automotive power, stalled, and shut off unexpectedly and stalled. The contact waited for a while, restarted the vehicle, and continued driving. The failure became persistent, and several attempts were needed to restart the vehicle. Recently, the failure reoccurred 4 times while attempting to drive to the residence. 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. The vehicle was inspected by a family member and was diagnosed with fuel injector failure. The vehicle was taken to the dealer, but was not diagnosed for the stalling failure. The dealer replaced the fractured fuel cap; however, the failures persisted. The manufacturer was not made aware of the failures. The failure mileage was approximately 68,000.
