While I was getting off the freeway, my vehicle displayed the “Service Brake Assist” warning. When I attempted to brake, the brake pedal became extremely hard and would not respond normally. The vehicle would not stop normally when I pressed the brake pedal. I was almost involved in a crash because I could not brake as expected. I had to use the emergency parking brake to help bring the vehicle to a stop and avoid a collision. Component/system: The exact failed component is UNKNOWN. Based on the “Service Brake Assist” warning and the extremely hard brake pedal, I am concerned there may be a problem with the brake-assist system, vacuum system/vacuum pump, brake booster, or related components. The vehicle is available for inspection upon request. Safety risk: This created a serious safety hazard because I temporarily could not stop the vehicle normally while exiting a freeway. I was almost involved in a crash and had to use the emergency parking brake to help stop the vehicle. Dealer/service confirmation: UNKNOWN at this time. The problem has not yet been confirmed by a dealer or independent repair facility. Manufacturer/police/insurance inspection: UNKNOWN/No inspection has been performed by the manufacturer, police, or insurance representative at this time. Warning/message: The vehicle displayed “Service Brake Assist.” The warning appeared before/during the braking problem. At the same time, the brake pedal became extremely hard and difficult to press normally. I am requesting that NHTSA investigate this incident along with other complaints involving 2018 Chevrolet Equinox vehicles experiencing “Service Brake Assist,” hard brake pedals, loss of brake assistance, and suspected vacuum-pump/brake-assist failures. I am concerned that this may be a safety-related defect that could cause a loss of braking assistance and increase the risk of a crash. I request that NHTSA determine whether further investigation or a safety recall is warranted.

Hard brake pedal and Service Assist message. This issue was recalled for trucks and larger SUVs but not the Equinox. This is a known safety issue to Chevrolet, making my vehicle undrivable until I can come up with the $1,500 to have it towed and repaired.
NHTSA complaint #11757499 — an unverified report by a vehicle owner.
My 2025 Chevrolet Equinox RS is experiencing critical active safety and electronic malfunctions. While reversing out of my driveway, the vehicle unexpectedly executed an aggressive "phantom braking" event, violently slamming on the brakes with no actual physical hazards or cross-traffic behind the vehicle. The Reverse Automatic Braking (RAB) and Rear Cross-Traffic Braking systems are hypersensitive and falsely triggering mechanical emergency stops, creating an immediate physical hazard and whiplash risk. Additionally, the Google Built-in infotainment system constantly suffers from communication freezes with Apple CarPlay and media apps like Pandora. Commands to select or play audio tracks freeze and fail to execute on the 11.3-inch screen, indicating a systemic software architecture defect affecting the vehicle's dashboard modules. The vehicle has previously been out of service for an extended duration (30+ days)due to a broken telematics module causing parasitic battery drain down to 3 volts, along with multiple dashboard error messages. The manufacturer has been unable to permanently resolve these electronic and active safety failures.

In May 2026 while driving home from her job in downtown St. Louis, my daughter was driving my equinox. While traveling on the highway at the speed limit of 55 miles an hour her brakes failed and she came within a few feet of rear ending a full gas tanker truck. She was able to maneuver to the shoulder of the highway and avoid an accident. After a few moments of the engine, idling the engine completely stopped working and shut down. After having the car towed to my local mechanic at a Midas shop, they began the diagnosis. I began similar research online to find cases of similar things happening. What was diagnosed is that the vacuum pump on the brake line was faulty and broke. Pieces of this pump made their way into my engine and ruined two of the cylinders in my engine. The car is now not drivable and needs a replacement engine. Chevy knew about this faulty, vacuum pump part and they did issue recalls on other vehicles using the same part. They have also issued technical bulletins to their technicians for a diagnosing this failed vacuum pump. I have tried to contact Chevy and they have offered me no assistance. I know a class action suit has been filed for this very same issue. Chevy is aware of this issue. Chevy‘s choice to use a part they knew was faulty. Almost led to the death of my daughter.

I own a 2018 Chevrolet Equinox. While driving at highway speed, the brake pedal suddenly became completely rigid and could not be depressed. The engine continued running normally, there were no warning lights, and I had to coast into a parking lot because I was unable to brake normally. The vehicle was towed to a Chevrolet dealership. The dealership diagnosed a failed vacuum brake booster and replaced the brake booster at my expense. After the repair, the exact same safety issue occurred again while I was driving at approximately 25 mph. The engine was running normally, there were again no warning lights, and the brake pedal instantly became rock hard and would not depress. The repair did not resolve the condition, and I no longer believe the vehicle is safe to operate. I am reporting this because the same loss of brake assist occurred before and after the dealership’s repair.

My granddaughter was driving the vehicle and experienced a catastrophic engine failure while driving down the road. Warning messages and audible sounds began and said to turn off the vehicle immediately. The brakes completely stopped working at that point. She pulled over immediately and called to ask what she should do. She was approximately 1/2 mile from home and she drove approximately 10mph to her driveway, pumping the brakes helped get the vehicle to her driveway. The vehicle was then towed to the dealership.

The contact owns a 2020 Chevrolet Equinox. The contact stated that while driving 80 MPH, the message “Service Brake Assist” warning light illuminated twice. The contact stated that while attempting to depress the brake pedal, the vehicle failed to respond as needed, causing the contact to engage the parking brake and manually shift the gear shifter to a lower gear to get the vehicle to come to a complete stop. A dealer was contacted. The contact stated that the check engine warning light was illuminated. The contact stated that the failure had occurred twice. The vehicle was taken to the dealer, where it was diagnosed and determined that the brake booster pump needed to be replaced. The brake booster pump was replaced, and the vehicle was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 94,000.

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 was turning at a green light while following behind a truck pulling a trailer. All of the sudden, the car did the automatic emergency braking. It slammed on the brakes in the middle of an intersection while I was going ~15mph, and gave me whiplash. I am not sure if the car got confused by the trailer in front of me, but this is the first time this has happened in my first few weeks of owning this car. I've read that many others have had this issue with the Chevrolet Equinox EV, and this poses a serious safety issue for drivers of this car and others on the road.

The brake vacuum pump has gone out four times now. While driving the brakes suddenly become hard as a rock to push. Of the four times two of them have been close calls to having a serious collision. This is a known issue with these vehicles so it blows my mind there isn't a recall for this.

This has happened 5 times since purchasing this 2026 Chevy Equinox RS. While driving, all of a sudden, without any notice, the dashboard lights up with warnings about "BRAKES"...Not exactly sure what is said because it doesn't stay on the screen very long. Next it says, STEERING ASSIST IS REDUCED..DRIVE WITH CARE....and a small area under, "Mileage till empty" says....BRAKE...in red, while still being in DRIVE. When pressing on the brakes to slow down to pull over, there ARE NO BRAKES.!!! The brake pedal goes to the floor and Equinox very slowly comes to a stop, so I can pull off the road and stop. Now if I turn off the engine, turn it back on, it seems to reset itself and I start driving again, not knowing when I might die because of the brakes going out again when someone pulls out in front of me. HOW CAN A VEHICLE THAT SPORADICALLY LOSES THE BRAKES, BE ALLOWED TO BE SOLD ON THE MARKET ??? This vehicle now has 13,147 miles on it and had very few when it first happened. We are now at 5 times, not knowing if the 6th time there will be death for my family to deal with. My dealer said they would let us know as soon as they learn about this issue, as they know nothing the 1st time..Several cases have been reported and our dealer failed to notify us about anything...Do I drive the Equinox until someone is killed or do I demand my dealership to furnish me a SAFE Equinox to drive until they fix mine. ? It's obvious that I will eventually be injured or killed in this Chevy Equinox caused by General Motors' incompetence..I am going to demand my dealer to furnish me with an equivalent vehicle.

To Whom It May Concern, I am submitting this formal complaint regarding my 2019 Chevrolet Equinox and the repeated failure of its brake vacuum pump. This is not an isolated repair issue. I have had the brake vacuum pump replaced or repaired three separate times, and each failure has placed my safety, and the safety of others, at serious risk. The first failure was the most terrifying. While driving approximately 65 miles per hour on my way to work, I suddenly applied the brakes and discovered that I had almost no braking assistance. The brake pedal became extremely hard, and the vehicle failed to slow down as expected. I was fortunate that traffic conditions allowed me to avoid a catastrophic accident. Had another vehicle stopped suddenly in front of me, or had a pedestrian entered the roadway, the outcome could have been fatal. Unfortunately, this was not an isolated event. The brake vacuum pump has failed two additional times, resulting in similar symptoms, including the sudden loss of brake assist and an extremely hard brake pedal. Each occurrence has left me questioning whether my vehicle is safe to operate. I recently learned that General Motors is facing a proposed nationwide class action lawsuit alleging that certain Chevrolet Equinox vehicles suffer from a defective brake vacuum pump that can fail without warning. According to the lawsuit, this defect causes a sudden loss of power brake assist, significantly increasing stopping distances and creating a serious safety hazard. The lawsuit also alleges that GM was aware of brake vacuum pump issues through technical service bulletins and customer complaints dating back several years. My personal experience mirrors these allegations exactly. The failures on my vehicle occurred without warning and created an immediate safety emergency. The fact that I have experienced this same dangerous failure three separate times strongly suggests that replacing the component alone has not corrected the underlying defect.

NHTSA complaint #11750550 — an unverified report by a vehicle owner.
No warning messages or check engine lights. However, I am concerned for my safety as my 2026 equinox I bought last year in may of 2025 from motion chevy in hackettstown NJ with 21k miles (as of now, bought it brand new last year) has a windshield distortion that when looking to the passenger side of the windshield, it’s very wavy and distorted and I already had a Chevy dealership named Mcguire’s Chevy in newton dismiss it saying others on the lot had the same issue (which they did as I saw but still unacceptable!!) I also noticed many other owners of my vehicle have the same complaint via online forums and even after several replacements from GM the issue persists which is unacceptable. The next issue are the rotors. They most likely are warped as when I step on the brakes the steering wheel vibrates slightly and the car shakes slightly which is not safe. Again, McGuire Chevy in newton dismissed it saying normal. And lastly, the front end of the car shakes when starting vehicle with or without the air conditioner on. It shakes for 10-30 seconds and you can feel it strongly in the brake pedal area as well as rest of the front end of vehicle before going away which seems unsafe, yet the first dealer Mcguire’s said it’s normal. I am having these issues looked at by a local GMC dealer and hope they rectify the issue or else GM may need to do a buyback if they can’t fix the issues and keep saying it’s “normal”. They opened a case with GM for the shaking so far not the other issues yet so we will see. Honorable mention is the blend door actuator making a noise (another known issue) on this car via online forums making a noise every time you go from hot to cold and vice versa. Mine is affected to just not severely but enough to where it’s very irritating and it’s had this issue since new and the McGuire dealer said it’s normal….. at this point GM needs to issue recalls instead of dismissing customers.

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.

The vacuum pump failed and my brakes went out pedal became extremely hard to push. I was driving on the highway at the time and was lucky I had a shoulder to slow down on and finally stop. I took the car to my usually mechanic who confirmed the vacuum pump failure but referred me to the Chevy dealer because this is a known issue. The dealer confirmed the pump had blown apart( their words to me) and that there are most likely debris now in the engine. No warning lights or alerts of any kind came on. Total suprise.
