While driving, my 2020 Chevrolet Equinox suddenly lost power and shut off without warning while I was pulling into traffic. The vehicle would buzz not crank afterward but would not restart. This created a safety hazard because the unexpected engine shutdown occurred while the vehicle was in motion. This is the second brake vacuum pump failure I have experienced with this vehicle. In 2022, the brake vacuum pump failed and was found shattered internally. At that time, the engine continued running, and the pump was replaced. During this most recent incident, the brake vacuum pump failed again, and the internal end of the pump broke apart. I replaced the vacuum pump and removed the broken pieces I could access, but the vehicle remains in a crank/no-start condition. The vehicle has not yet been inspected by a dealership or independent repair facility. However, after seeing the shattered pump components, a couple of mechanics I know expressed concern that the broken pieces may have affected the engine timing. That has not been confirmed. The failed pump and replacement parts are available for inspection.

I bought the 2020 equinox May the 9th 2026 the dealership concealed a lot of things going on this vehicle and I complain to them two days after purchase he told me I was stuck with it in the meanwhile as I drive the vehicle I have had repairs done but it's something going on with the acceleration it accelerates on its own sometimes and slow to pick up speed. The steering seems to get away from me at times that makes me feel like I'm going to lose control when driving. I have almost had a couple of accidents since then so what really worries me is the steering problems which I just had a little alignment done today July 15th 2026 and the accelerating from time to time went backing up or pulling off. I do feel like the safety of others can be at risk for should I say my safety is that risk at times so I am extremely cautious when I'm driving. No I have not had really anyone to look at I have been having a car looked at for many issues but that issue I am still trying to get in to see a mechanic that I'm used to dealing with but he's been backed up. No there are no lights of any such but when I purchased it the sensors in the tires and I've had that replaced and I've noticed this situation with the acceleration when I bought the vehicle and the slow speed pick up when driving.

As I was coming to a stop at light my brakes became very difficult to push the pedal down to stop. It took everything in me to get the vehicle to stop before entering the intersection and oncoming traffic. I was able to get the vehicle parked safely in a nearby parking lot but then the engine wouldn't start it just kept trying to turn over. The brake assist error popped up, and then the check engine light came on. I was able to get it started again about 20 minutes later, all the same warnings and lights. I white knuckled the drive back to my house... Once I got home the engine was smoking, smelled like it was burning, and oil was spilling out all over the place underneath, impossible to see where a leak was as it was coming from the entire engine. There was ZERO warning with the vehicle, no issues up to this point, and suddenly the equinox is now useless in my driveway unable to start with oil still leaking in multiple spots. An oil pan under the main leaking area, but there are still multiple areas of oil spilling even a week later. Oddly enough my onstar report for the month came to email a few days later reporting perfect engine health and zero issues - even thought the vehicle can't start now.

The contact owns a 2020 Chevrolet Equinox. The contact stated that while driving approximately 5 MPH and approaching a stop sign, the brake pedal was depressed and there was a thumping sound coming from the brake pedal, with the message “Service Brake Assist” was displayed. The vehicle was taken to the residence and parked. The contact stated that the next day while driving approximately 63 MPH, the message "Reduced Engine Power" was displayed. The contact exited the highway, and while attempting to depress the brake pedal, the pedal was firm, and the vehicle failed to slow as intended. The contact continued to depress the brake pedal with force, and the check engine warning light was illuminated. The vehicle slowed down eventually. The vehicle was taken to an Auto Parts Store and a handheld diagnostic machine to diagnose the vehicle. The contact stated that the vehicle was turned off and failed to restart. The vehicle was restarted after three attempts. The vehicle was taken to the residence and the following day, the vehicle was towed to an independent mechanic where it was diagnosed and determined that the vacuum pump, camshaft, and timing belt needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 111,000.

December 2025 I was at a complete stop and the car clunked and the brake pedal got hard hard to push and then a couple months later a brake sensor light came on and when I plugged the code reader into it, it said give me a brake sensor code, and then it started slamming on the brakes all by itself when I went to takeoff hard like give you whiplash hard and it didn’t just do it once it did it a few times and then it wouldn’t go into reverse and then it wouldn’t go in neutral, and then it started smoking. My safety was affected by it, slamming on the brakes that could make someone hit me. It could hurt my back and neck. Yes, I have proof. Yes, I notified the dealer. Yes the vehicle has been inspected and I got an estimate by two different Car Lot the one I bought it from Ken valor motors, and Matt Mazzoni’s I have. Plus I have diagnose diagnostics printouts from OnStar and this is a 2020 vehicle. It should not be having these problems and now I’m stuck paying for a vehicle that I can’t even drive.!!

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.

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.

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?

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 bought the equinox with 30,000 miles on it. It's at 67,000 now and I maintain the vehicle regularly. So why have I replaced the throttle body already because it gets dirty fast? And now I'm getting a check engine light for P2099 TurboCharger Underboost. When the vehicle is not old it's 5 years old, hasn't been driven hard. So why are you using a crap 1.5L engine with a turbo that is notorious for these issues??? And what's worse the engineering is horse s$*t, because the air inlet hose is only one time use. But the part is underneath it where you can't reach. Why has this not been recalled yet????????? It's not but a scam to make you take it to a dealership. I'll continue to write complaints this is not right. And I'll never buy one again.

While driving, my engine light came on. After taking it in, it turned out that I had water/oil freezing in the intercooler. This could have been very dangerous when I was driving. I have had the GM Wrap put on it. I am hoping that this will not be a problem again.

I would like to formally file a safety complaint regarding my Chevrolet vehicle and to express concern over Chevrolet’s handling of a known defect. On January 22, while driving to work in cold weather conditions, my vehicle experienced a sudden and dangerous malfunction. The engine unexpectedly revved to approximately 4,500 RPM, the check engine light illuminated, and the dashboard displayed an “Engine Power Reduced” message. Despite removing my foot from the accelerator, the vehicle did not slow down as expected. I was able to pull over to the side of the road and bring the vehicle to a stop. I immediately contacted my local Chevrolet service department and was advised to bring the vehicle in six days later, the following Friday. Due to the safety risk, we did not use the vehicle during this time out of concern for a potential accident. When the vehicle was inspected by the Chevrolet dealership, we were informed that Chevrolet had identified this issue as being related to cold weather operation and that a custom shield had been designed to address the problem. We were also told that Chevrolet vehicles were not adequately designed for cold weather conditions, which led to this failure. Despite this acknowledgment and the fact that Chevrolet has engineered a corrective part, we were informed that the repair—costing approximately $1,600—is not covered under our extended warranty, as the shield was not installed on the vehicle at the time of purchase. The vehicle remains unsafe to drive. When accelerating, engine RPMs surge from approximately 2,500 to 4,000 RPM, and the vehicle can suddenly decelerate, creating a serious risk of rear-end collisions if a following driver is forced to brake abruptly. This issue represents a significant safety hazard. Chevrolet has acknowledged the defect by creating a corrective part, yet is declining to cover the repair cost, leaving the responsibility with the customer for a known design issue. Please let me know my next step
