2020 Chevrolet Equinox Brakes

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.

The power brake booster failed suddenly causing the brake petal to become hard. Almost caused an accident as I suddenly lost the ability to brake. There was no warning prior to the failure. After the failure a service warning for brake assist appeared. The vehicle was been inspected by an auto service provider.

With the vehicle around 73,000 and while driving on the highway, the brake system failed to fully function. Using extreme pressure to compress the brakes the vehicle finally slowed and came to a stop with out injury or vehicle accident. After getting the vehicle moved to an independent service center, and further inspection it was found that the vacuum pump exploded. After researching it appears the problem is consistent with other reports but no resolution has been made until it's too late. The component is not currently being inspected by the manufacturer and has only been inspected by independent service center. No warning lights or other symptoms displayed prior to the failure and the only time it first appeared was on the highway at high speeds.

Brake vacuum pump has failed. my brake pedal I had to put my full weight on to stop my car. I almost crashed into the person in front of me. It was my full weight and all the way to the ground in my car wasn’t stopping.

The vacuum pump seized and broke and sent debris into the camshaft

Getting off the highway and brake pedal is just hard can barely push it. It stopped but barely.

I purchased this vehicle as a Certified Pre-Owned vehicle from George Moore Chevrolet in Jacksonville, Florida, in October 2023. At the time of purchase, the vehicle had approximately 35,000 miles, and it now has approximately 60,000 miles. I have maintained all recommended service intervals and oil changes as required. On June 14, 2025, while stopped at a traffic signal with my foot on the brake pedal, the pedal suddenly sank to the floor, causing the vehicle to roll forward into traffic unexpectedly. I was able to place the vehicle in neutral and then park to prevent a collision. After turning the vehicle off and restarting it when the light changed, the brakes continued to fail. I carefully maneuvered to a nearby area behind a warehouse and allowed the vehicle to come to a complete stop by shifting into neutral. I contacted a tow truck through my State Farm roadside assistance program and had the vehicle transported to my local mechanic. Upon inspection on June 16, 2025, the technician determined that the brake lines were corroded and leaking. Initially, he suspected the master brake cylinder, but it was confirmed not to be leaking. He noted that the metal-braided portion of the brake line had completely deteriorated on one side and was severely compromised on the other. Both brake lines were replaced to restore braking function. Fortunately, I was able to avoid an accident, but this was an alarming experience that I have never encountered in any vehicle I have owned. My mechanic expressed concern about the extent of corrosion on such a relatively new vehicle and indicated this could represent a broader safety issue. I respectfully request that this matter be documented and investigated to ensure that other drivers are not placed at similar risk.

I was driving just got off the freeway and went to hit the brakes and the brake pedal was hard as a rock I had to use force to slow down to safely get over from the left lane to the right lane to get into a parking lot was a pretty scary experience, called AAA had it towed to the dealer they said the vacuum pump failed which I suspected because of the other complaints regarding the same thing, there was no recalls on my car dealer fixed it under warranty and they said there was no damage to the camshaft. The dealer was amazing and would reccamend them, I also had to pay 100 deductible. As others have stated theres a recall on the vacuum pumps but certain Vin #s are not included. Gm needs to included all Vin #s for the equinox in the recall whats it gonna take somebody to get killed!

I am filing a safety complaint regarding a failure of the vacuum pump in my 2020 Chevrolet Equinox. The failure occurred without warning and severely impacted the vehicle’s braking performance, posing a serious safety risk while driving. When the vacuum pump failed, I experienced a hard brake pedal and a significant loss of braking power, which made it difficult to stop the vehicle safely. Thankfully, I was not in heavy traffic or approaching a stoplight at high speed when it happened—otherwise, it could have resulted in a serious accident. After researching this issue, I discovered that vacuum pump failures appear to be a recurring problem in other GM vehicles of similar model years. It is extremely concerning that such a critical component could fail prematurely and without adequate warning. I believe this issue should be investigated for a potential defect and safety recall. I urge the NHTSA to look into this matter to ensure the safety of other drivers who may be at risk due to this defect. Thank you for your time and attention.

This past weekend, while driving my 2020 Chevrolet Equinox, I experienced a sudden and complete brake failure. I was turning into a residential neighborhood at approximately 20-30mph when the brakes locked up without warning. Despite pressing the brake pedal, the car would not stop. I attempted to shift into park, but the vehicle continued to roll forward. I had to engage the emergency brake, which caused the car to come to an immediate stop. Thankfully, there were no cars in front of me, but I came dangerously close to hitting a cement wall head-on. This created a serious risk to my safety and potentially to others had the situation occurred in traffic or near pedestrians. There were no warning lights, noises, or prior symptoms indicating an issue with the braking system. The vehicle has since been towed to the dealership and is currently awaiting inspection. I've learned that there are existing recalls on other VINS for the 2020 Equinox related to an incorrect lubricant used in the manufacturing process of the rear brake calipers. This defect can cause the calipers to swell, leading to excessive brake drag. Over time, this drag may result in overheating and possible brake lockup, which aligns with what I experienced. The component appears to be the braking system, specifically involving the calipers or pads. At the time of writing, the failure has not yet been confirmed by the dealer. This issue is extremely dangerous and could have resulted in a severe crash. I am reporting this in hopes that it contributes to a broader investigation, especially if this problem extends beyond currently recalled VINs.

Service brake assist

My breaks stopped working while I was driving, they became hard to press and unable to function. The vacuum pump attached to the engine failed. The vacuum has broken pieces that are now inside of the engine. No warning indicator lights appeared before the incident. As far as I'm aware other similar models are having the same issue but my vin was not included in the recall.

The contact owns a 2020 Chevrolet Equinox. The contact stated while depressing the brake pedal, the brake pedal was hard while depressed, and the vehicle failed to immediately stop, causing the braking distance to become extended. During the failure the message "Brake Assist" was displayed. The vehicle was taken to the local mechanic who replaced the brake pads and brake rotors, but the failure persisted. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 71,000.

When first breaking on the exit ramp after a 2 hour ride on highway the rear breaks made a loud grinding sound & took longer to stop with 2 cars in front of mine. I put flashers on & pulled as far to side of road incase I was unable to stop at the bottom of the exit (down hill) to avoid collision with the 2 cars in front of me. Previously my vehicle shown no signs of any issues. There were no sounds coming from breaks, no issues slowing down or stopping, & no lights on dashboard to indicate an issue of any kind. I looked my Chevy Equinox up and saw that there was an isdue with the rear calipers and many had been reported and recalled. My VIN doesn't show my calipers have been recalled. However, the GM site states if there is an issue with the rear breaks/ calipers to report it and Chevy will repair the issue. Many Chevy Equinox owners have taken to the internet to report the same issue, there are also reports that only 166 were recalled. This is clearly a manufacturing error and not normal wear & tear. I bought my 2020 Equinox brand new in 2021, it was unsold in 2020. Please help myself & the other Chevy Equinox owners make Chevy take responsibility & fix this error before people are injured or killed because our breaks give out unexpectedly.

Brake assist fail

I was driving and the “service brake assist” light came on and I then the brake pedal became stiff and so hard to push! I was driving on the expressway and almost couldn’t stop my car. No warning at all. It happened as soon as the light came on.

In June of 2023 the brake booster vacuum pump failed, I took it to my regular repair shop and paid for it to be repaired. March 1, 2024 I was driving out of town and again the brakes failed, took it to Weimar Chevrolet in Cumberland MD to once again after less than 10,000 miles to be repaired again. Thankfully the dealership coordinated with the original repair shop and was able to do the repair this time at not cost to me (except I had to pay for a rental for 4 days)

[XXX] My wife received a warning light that the Brake fluid was low, upon the husband checking under the hood after cleaning the reservoir cap and opening the cap and looking inside of the reservoir I could see that there was no visible brake fluid in there. Using another car I purchased Prestone Dot 3 and filled the reservoir it, it took 8 oz out of 12 oz. The 2020 Equinox Premier only has 34,500 miles. On [XXX] I have an appointment to bring the vehicle to Midas via being towed because of this issue, it is not safe to drive there.

Hit my brakes and had nothing but a hard pedal NO BRAKES AT ALL! This almost caused a major accident being speed limit is 70 and I could not stop the car. There was no warning light until I shut it off and turned it back on then lights blinked and said brake assist failure then the warning disappeared once again. This is very scary and I cannot believe there were other reports and nothing has been recalled.

Brake control lost with no warning. Friend whom bought same car 2 days after me experienced same scenario around October 2023. I just dropped off my kid and I was coming off the highway! I could have killed others and if happened 20 mins prior my children! I'm a single mom and my kids only have me. There's no way this is coincidence on the same make, model, year! There has to be a faulty brake system that needs addressed before people do die!! I've been without my car for 3 days now and no one has answers!

Was driving (in July) through a parking lot when brakes became hard to push. After stopping car, it would not start and went into battery save mode. Car was towed to Chevy dealership in Paducah, Ky. Vacuum pump was replaced and damage to cam shaft and timing chain. Problem was fixed after about $5800 of repairs. Now 2 months later, was driving and noticed “service brake assist” light came on, and brakes were hard to press. Luckily was at a low speed and able to pull over on the side of the road. Car was towed to the local Chevy dealership in Hopkinsville, ky. It is currently waiting for diagnosis of probably the same issue. first incident happened in July, 2nd was at the end of august.

Faulty Brake Booster Vacuum code on after 60,000 miles

When I was driving my vehicle, I came up to a red light and my brake pedal was hard and I could not stop the vehicle. The brakes would not work when I tried to stop. With fast acting and thinking, I was able to pull over to avoid hitting the vehicle in front of me, luckily no other cars were around at that time. Mine and my child's safety were at risk when the vehicle would not stop and we could have been in an accident from the brakes not working. The vehicle is currently at the dealership getting diagnosed. No warning sings, warning lamps, messages or other signs happened before, during, or after the failure of the brakes. The brake pedal was so hard you could not push it down at all.

2020 Chevy equinox vacuum pump. Impossible to get the part, safety hazard, no accident yet, takes 2 feet to hold peddle down. No Chevy dealer will help me, i need to go to work.
