2020 Chevrolet Equinox

Multiple occasions of “engine reduced power” and vehicle stalling/jolting/jerking when trying to go over 45 mph. When trying to go to work Monday - on the interstate, it was jerking/jolting when trying to increase any speed and brakes were getting harder to press on, decided to try to reduce speed and get pulled over without the brakes, car was overheating completely. Now seeing multiple people have had this issue with the same car - I’m not sure whether it’s comforting that I’m not the only one or terrifying to know there’s multiple vehicles on the road experiencing this dangerous issue. Seeing a pending lawsuit did not surprise me one bit - I am not happy whatsoever about risking my own life and others on the roadway due to this not being a priority in the first place to correct before selling this vehicle to me, buying it with my hard earned money. Greedy greedy.

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.

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.

The brake booster vacuum pump, in the words of Meineke, massive failure. The pump locked up and exploded, there are parts of at least under the valve cover. The failure resulted in the ruining of the camshaft, as this pump is controlled by the camshaft. The end of my camshaft looks like a mushroom head. This failure is currently in the investigation part of a class action law suit in which I am adding my name to the hat. My wife was driving at the time and fortunately was not injured during this catastrophic failure with what seems like planned obsolescence. I am also glad the kids weren’t in the car when this happened. We had just crossed 100k miles.

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.

This issue has happened to me twice now. Dec 19th 2024 I Driving on a highway at about 60mph, traffic slowed, I tried to stop and instantly had no brakes at all. There was a light that came on as I was applying the brakes, "service brake assist". Had it towed to a mechanic and they replaced the brake vacuum pump. We ordered this part from a Chevrolet dealership so we knew it was the proper part. Most recent was two days ago, Nov 10th 2025, NOT even a full year later. Driving about 55mph, tried to stop and no brakes again with the same service message. It is currently at the shop being repaired. The part is under warranty but of course labor isnt. Both times this happened, I had to drive over on to the shoulder to avoid causing an accident. Prior to this, there was no warning that there was anything wrong with the brakes. The only place that can confirm this issue is the mechanic shop as they are the ones doing the work. Attached is a copy of the receipt from the first time.
