Automatic Emergency Braking problems of the 2026 Chevrolet Equinox

While pulling forward out of a parking lot at a low speed, the vehicle's automatic emergency braking (aeb) system suddenly and aggressively engaged without warning. There were no vehicles, pedestrians, or obstacles whatsoever in the vehicle's path. The deceleration was extremely severe and violent, mimicking the sensation of hitting a brick wall. This unprompted, false-positive system activation subjected my body to intense, sudden forces, resulting in a painful back injury that requires medical attention. The system completely failed to accurately evaluate the path of travel, creating an immediate and unexpected hazard to my physical safety and that of anyone following behind me.

On xxx, at approximately 5pm est, my wife stopped our 2026 Chevrolet Equinox ev 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, continued onto neighboring property, and continued through grass. 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 at this point and was able to help stop the vehicle, entered it and apply the brakes. My wife also tried to enter the vehicle and stop it during these events which ended in 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. Two Chevrolet ev concierge agents separately were unable to retrieve remote diagnostic information. The vehicle is currently at my house and has only been driven to secure it in the garage since the incident. Opened a case with gm ev concierge and they escalated it to "the executive team". It should be towed to a dealer today. Police report submitted but I do not current know the report number. Information redacted pursuant to the freedom of information act (foia), 5.

Three times over the past month, this car has slammed the automatic emergency brakes, thinking there was an obstacle in the road. Each time, it has caused whiplash to everyone in the car, feeling like we were slammed by another car. It is related to the collision avoidance and is triggered by either a shadow on the road or a glare. If I turn off the feature, I have to do it every single time I get in my car. If I forget to turn off this dangerous feature, it could trigger again. I'm beginning to get nervous driving it, thinking it could engage at any second. Eventually, someone will crash into me because it's so sudden, the car behind won't be able to stop. This is apparently a major problem with others I've seen online with no remedy.

I feel compelled to report this issue after 3rd incident and also after raising with the dealer service. I think this is a very very serious issue which should be investigated and dealt with promptly before it results in serious death or debilitating injuries. Let me describe the latest incident that happened yesterday with me in [xxx] between on xxx between 10:30 - 10:45 am pt. I was in a parking lot looking for a parking spot possibly driving at about 10-20 mph. A vehicle approached from the opposite side and it suddenly it slammed emergency braking. I and my family were shaken and felt a crushing jerk. This has also happened at least twice before - one time when I was pulling out of my driveway and another time on highway 1 in [xxx] near [xxx]. The highway incident could be very dangerous but possibly the slow traffic saved us. Driver behind me who is a friend called me immediately asking why I braked unsafely which I told him I did not. I have also 2 prior issues before the latest to the dealer who listened to me and documented it but I was told they don’t know anyone reporting this issue. Internet forum talks about this issue but oem is possibly ignoring it. The dealer says they updated some camera software but that’s about it. This 3rd incidence has shaken me and I thought of reporting to you. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

At around 7k miles while driving the brakes and steering suddenly stopped working and all warning lights came on including check engine light. The dealership said it was the main brain and the fixed it. Then last Thursday night while driving on the highway my brakes stopped working suddenly and all warning lights came on again. It is at the dealership now and they are now saying the problem is the bcm. I’m honestly scared to drive on the highway now. I’m really scared someone will get hurt or killed from this vehicle if it happens again.

The vehicle cannot be shifted into neutral if the vehicle runs out of gas. There is no way to shift to neutral and roll it to the side of the road. The vehicle ran out of gas on the interstate, automatically braked and could not be moved out of the middle of the interstate. To make matters worse, this was in a construction zone.

I was driving down my neighborhood road about 20mph there were no other cars around on the road at all only mailboxes and cars parked in driveways. The car suddenly slams the brakes hard enough the tires were squealing and threw us forward thankfully me and my child had our seat belts on. It scared the heck out of us cause there was no warning and definitely not expected.

The inability to permanently turn on the warning only option for front and rear emergency braking after the latest ota update. Phantom braking conditions still exist for this model and occur at unexpected times causing potential rear end collisions with following vehicles.

The contact owns a 2026 Chevrolet Equinox. The contact stated that while driving at an undisclosed speed, the forward collision avoidance automatic emergency braking engaged, with the forward collision avoidance warning light illuminated. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure due to an ongoing lemon law case against the manufacturer. The approximate failure mileage was 17,280.

I was driving and slowed down to enter a small roundabout. Upon trying to enter the roundabout the cars emergency braking slammed on the brakes to a sudden hard stop. No other cars were in the roundabout, but I believe it may have seen the curb. In any case, I was extremely lucky that nobody was behind me, or coming around the roundabout, as it took a bit to get the car to let me go again.

My wife was driving home after picking up my daughter from a nearby school around 3:30pm on Thursday 1/22/2026. She was driving down a road maybe at 35mph and while her foot was on the accelerator the car did a hard brake though there's nothing in front of her nor is the adaptive cruise on. She didn't hit any button and was taken by surprise along with my daughter. Luckily the car behind her was far away and didn't hit them. We haven't yet informed the dealer. This has happened before and the car has about 3900 miles on it.

The brake system, specifically the master brake cylinder and/or associated brake system components, failed or malfunctioned. The defect results in a sudden loss of braking performance without warning. Yes, the vehicle is available for inspection upon request. It has remained in the continuous possession of the authorized Chevrolet dealership since January 13, 2026, and has not been returned to service. The defect involves the primary braking system, which is a critical safety component. Sudden and unexpected loss of braking ability significantly increases the risk of a collision, serious injury, or death to the driver, passengers, pedestrians, and other motorists. The vehicle was deemed unsafe to operate due to the risk of brake failure. The problem has been confirmed by the authorized Chevrolet dealership. The service department diagnosed the issue as a defective master brake cylinder and/or related brake system components. The dealer advised that the condition presents a safety risk and that the vehicle cannot be safely operated until the issue is addressed. The vehicle has been inspected by an authorized Chevrolet dealership acting as the manufacturer’s representative. The manufacturer has been made aware of the problem. No inspection by police or an insurance representative has occurred, as no crash took place. The vehicle remains unrepaired as of February 9 due to parts unavailability. There was no adequate warning that would have allowed the driver to anticipate the loss of braking performance. The defect results in sudden brake failure without sufficient advance warning, which is a significant safety concern. The issue was identified in January 2026, at which time the vehicle was taken to the dealership. On January 13, 2026, the vehicle was removed from service and has remained at the dealership continuously since that date. The vehicle remains out of service because the master brake cylinder is on backorder. There is no eta, and as a result, no repairs.

I was traveling about 45mph and the SUV emergency brake system activated, it scared me and my passengers, the guy behind me was even more scared. I had the front seat passenger immediately deactivate the emergency braking system.

Vehicle went into brake assist failure and would roll in neutral but no drivetrain power or brakes. Dealer took 3 months to find part. Acceleration jerky at stop or while driving. Pedal too sensitive. Constant traction loss from stop at lights and stop signs if not careful on dry pavement. Mode selection to rain/snow helps by restricting power, if it is remembered to be turned on. With rain and snow on the road it becomes challenging. Aggressive safety features that include the automatic braking and alerts. Brakes and alerts on double turn lanes and going forward near passing objects on the side.

Car info – 2026 Chevrolet Equinox purchased 9/25/25 stock# [xxx] VIN: [xxx] type: lt 4dr all-wheel drive on 1/8/26, I took my 2026 Equinox to northpointe Chevrolet because I had a warning light that came on every time I started my car. The warning light states, ‘service driver assist system’. The alert had been coming on for about a month but I had to cancel my previous two appointments due to bad weather. I explained to the man in service that I would like the automatic braking feature deactivated on my car as well as the alert light corrected. I told him that I was coming up to a red light and I was slowing down when my car automatically slammed on the brakes and gave me whiplash. The man in the service department asked me if I lived on a back road. I told him that I did and he told me that is why I am having this issue. He stated that the dirt and mud caused the wires on the sensor under the front bumper to corrode. He stated that the sensor was supposed to be waterproof/weatherproof but they are not. He showed me where the sensor was on my vehicle. He also stated that the automatic braking was not something that they could turn off because it was a safety feature. He also told me that the broken sensor causes the automatic braking system to operate. I am now afraid every time the red light comes on in my car that the brakes are going to slam on again so I slow way down. My neck has not fully healed from the first time. What would happen if I am driving down the interstate going much faster that I was the last time they automatically stopped the car suddenly. He then explained that the issue was not covered under my bumper-to-bumper warranty because the dirt caused the issue – apparently the waterproof sensor box had no bearing??? I have only made 2 payments so far on this brand-new car. I was charged $87. 34 for the diagnostic check and I will be charged another $558. 25 when the part comes in to repair my sensor.
