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.

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 issue was identified in January 2026, at which time the vehicle was taken to the dealership.

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.
