The worst model year for it is 2018.
On approximately 09/04/2026, while driving my vehicle and slowing to a stop, I applied the brake pedal and it suddenly became extremely hard to depress. At approximately the same time, the steering became very stiff and difficult to turn. I believed I had lost normal braking ability and had difficulty controlling the vehicle while attempting to stop. The engine then shut off on its own. After the vehicle stopped, attempts to restart it were unsuccessful. The engine would crank/attempt to start but would not complete the ignition cycle and remain running. A ticking noise was also present. The vehicle remains available for inspection and is being towed to a local GM dealership for diagnosis. The specific component responsible for the failure is currently UNKNOWN. The vehicle previously generated diagnostic code P050F in January 2026. Following the 09/04/2026 failure, diagnostic code P0017 was identified. I did not receive P0017 prior to this incident. I did not observe an overheating warning or temperature-gauge indication showing that the engine was overheating before the vehicle shut down. The incident created a safety risk because the brake pedal became extremely hard to depress and the steering became difficult to operate while the vehicle was in motion, significantly affecting my ability to slow and control the vehicle. There was no collision or injury. As of the date of this complaint, the cause has not yet been confirmed by a dealer, independent service center, manufacturer, police, or insurance representative. The vehicle is being taken to a GM dealership for diagnostic inspection. I can provide the vehicle and subsequent diagnostic/repair documentation for inspection upon request.
NHTSA complaint #11763908 — an unverified report by a vehicle owner.
While operating my vehicle, I experienced a sudden, catastrophic failure of the power-assisted braking system. The brake pedal completely lost hydraulic pressure, plunging effortlessly all the way to the floorboard. The vehicle failed to respond to normal foot-pedal application. Emergency stopping power was only achieved by pushing the pedal into the absolute floorboard, which engaged an emergency mechanical override and forced the Anti-lock Braking System (ABS) pump into a violent stutter/pulsation to halt the vehicle. No dashboard warning lights, diagnostic trouble codes (DTCs), or fluid level sensors illuminated prior to or during the braking failure. A certified automotive repair facility diagnosed the root cause as a total internal seizure and mechanical failure of the engine-driven brake booster vacuum pump. Because the vacuum pump is driven directly by the engine, its sudden lockup sheared and severely damaged the drive slots on the exhaust camshaft, necessitating an intensive engine teardown, camshaft replacement, and secondary component repair totaling $2,390. This design poses an extreme, life-threatening safety risk. The total loss of braking assist occurs without warning, and the mechanical failure simultaneously compromises internal engine timing components while moving at speed.
NHTSA complaint #11763379 — an unverified report by a vehicle owner.
At approximately 5pm EST, my wife stopped the EV vehicle after backing out of the garage and put the vehicle in park. After exiting the driver's seat, she was outside the open driver's door, had both feet on the ground and cleared the door enough that she was preparing to close it, when the vehicle began moving with no one in the driver's seat. The vehicle traveled down our inclined driveway, across the street and striking my neighbor's house. A [XXX] neighboring child was in the vehicle's path. My wife believed the vehicle would strike the child and screamed for her to move. The child moved clear before the vehicle reached her, and no contact occurred. The vehicle stopped when it hit the left side of the neighbor’s garage causing damage to the stone siding and framing of the garage. The vehicle then started to move forward over the lawn and into the street. At some point after it started moving forward the neighbor, an adult male, was attempted to stop the vehicle physically but was unable to. I came out of the house and saw what was going on and was able to help stop the vehicle, entered it and apply the brakes. My wife also tried to enter the vehicle to stop it during these events causing her to get ran over, substantial scraps, bruising and other injuries. We are reporting unintended movement after driver exit and request investigation of park engagement, the shift-by-wire system, electric parking brake, Automatic Vehicle Hold/driver-exit functions, reverse automatic braking and propulsion/brake controls. 2 GM EV Concierge agents separately were unable to retrieve remote diagnostic information. The vehicle was towed to [XXX] in [XXX] with very specific instructions. I opened a case with GM EV Concierge and they escalated it to "the executive team". Despite multiple calls and emails the executive team has not reached out. The case was even closed once and I had it reopened. I opened ticket # XXX but can't find it so I'm opening this one.

On 3 occasions, the last happening today (XXX) traveling north on XXX toward [XXX] at approximately 14:05, the vehicle has stopped abruptly and hard, and will then release. Today, it took it longer to release. When it occurred this time, it braked just as hard but longer, so I had to cross two lanes so the cars behind me would not hit me. The cars swerved around me and the car eventually let go and I was able to accelerate from that dangerous position on the side of the highway. The first time it happened, someone was pretty close behind me. The car stopped hard, real hard, but let go quickly enough to accelerate before a collision. The second time, there was no one in front or behind us, and we were safe. It hadn’t happened in a while, today. We’ve downloaded 2 or 3 software update, and I was hoping it fixed the issue. It did not. Today the car stumbled and the rpm’s jumped. I feel like the car momentarily braked while I was accelerating.

NHTSA complaint #11759717 — an unverified report by a vehicle owner.
In my chevy equinox 2018 my vacuum pump and brake booster failed when I was driving and I could not brake. I slid into the gravel side of the road on the 138, luckily there were not alot of traffic at the time cause I would have caused a major accident. Never had any braking issue till now. Now this is a major financial hardship on me to fix this issue that should have not happened if it got recalled to fix this issue on this certain model. No lights, no indicator lights or anything came on either which was scary. And I have no problems or any other issues with the equinox. It just failed all of a sudden.

NHTSA complaint #11759542 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11756326 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11755541 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11753062 — an unverified report by a vehicle owner.
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.
