Driving in the freeway at 70 miles per hour with adaptive cruise control on car went crazy with emergency lights and braking the vehicle In middle of freeway No accident Also lane Asíst is not working

The contact owns a 2026 Chevrolet Equinox EV. The contact stated that the vehicle had experienced phantom braking on two separate occasions. The contact stated that while slowly reversing out of the garage, the vehicle experienced phantom braking and suddenly stopped. Additionally, while driving approximately 60 MPH, the vehicle experienced phantom braking and decelerated abruptly, causing the contact to sustain a mild neck injury. No medical assistance was required. The cause of the failures was not yet determined. The local dealer was notified of the failure, and a service appointment was scheduled. The manufacturer was not yet contacted. The contact stated that she had previously experienced the same failure with a company vehicle of the same make and model. The failure mileage was 7,861.

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 Equinox EV has rear Automatic Emergency Braking. On multiple occasions while backing up the vehicle's AEB has activated by slamming on the parking brake. A check of the rear camera and sensor system shows the vehicle detected nothing. A visual check also shows nothing behind the vehicle that's outside the sensor system's.

On February 23, 2026, while driving my 2026 Chevrolet Equinox EV home from Folsom Chevrolet following a prior repair visit, the “Service Park Assist System” warning illuminated, first intermittently, then after a few miles, continuously for the remainder of the 11-mile drive home. During the same drive, while reversing with no objects present behind or around the vehicle, the automatic emergency braking system activated and applied the brakes with significant force without cause. The vehicle was returned to Folsom Chevrolet (Repair Order #559378, opened February 23, 2026). Diagnostic code U1126 was found — indicating the left rear short range radar sensor had lost communication on CAN Bus 8. The sensor module was on national backorder, keeping the vehicle out of service for approximately two weeks. The module was replaced and programmed on March 7, 2026. Safety concern: Unexpected activation of automatic emergency braking with no objects present creates a serious collision risk from following traffic. This failure occurred on public roads during normal driving. Additionally, the U1126 CAN bus communication fault is the same vehicle communication architecture implicated in the battery/electrical failure documented in Repair Orders #558923 and #559167, suggesting these failures share a common root cause in the vehicle’s electrical communication network rather than representing isolated component failures.
