2025 Chevrolet Equinox service brakes problems

“Multiple phantom braking events have occurred since we purchased this vehicle, but traveling forward and reverse. We have been forced to turn this automatic emergency braking off and set to alert only.”

“INCIDENT DESCRIPTION: On October 20, 2026, at approximately 11:15 AM, I was driving my Chevrolet Equinox EV and was stopped at a red traffic signal. When the light turned green, I began accelerating normally into the intersection. Suddenly and without warning, the vehicle experienced a severe "phantom braking" / false Automatic Emergency Braking (AEB) event. The vehicle’s emergency braking system engaged violently, bringing the car to an abrupt, full stop in the middle of the intersection. There were NO vehicles, pedestrians, or obstacles in front of my car or anywhere in my path. A vehicle traveling directly behind me was forced to slam on their brakes and narrowly avoided a rear-end collision. This unexpected hard deceleration caused severe panic and created an immediate, life-threatening traffic hazard. Had this sudden stopping occurred at highway speeds or above 25 MPH rather than starting from a green light, it would have resulted in a severe crash. CRUCIAL CONTEXT / RECENT SERVICE HISTORY: This life-threatening failure occurred directly after taking my vehicle to Coggin Chevrolet at the Avenues (Jacksonville, FL), where technicians performed software…”

“This car locks up sometimes while driving in normal traffic which is very dangerous, resulting in a whiplash for me the driver and almost causing rear end collisions to my car from the abrupt stop in moving traffic. All five abrupt stops happened with all the collision warning systems on. Three happened between 2/1/25 and 8/1/25. I called GM onstar to report two of them. After the third event I switched all braking systems to alert only from brake and alert. Two recent events happened between 10/8/26 and 10/13/26 after I had my car serviced for a GM safety recall N25252824 Brake System Control Module on 10/7/26. I switched all brake systems to brake and alert assuming that GM had fixed this issue. Both recent events were during light rain. I called Onstar to report the second event and brought my car back to the Chevy dealer on 10/15 for review. This issue is abrupt, with no warning. The car simply locks up no matter the speed. The issue is well documented and is all over the Equinox EV forum. I am speaking to a law firm as well about the issue. Thank you.”

“The braking system failed to communicate with the vehicles computer system. This communication failure occurred while driving and set off all kinds of alarms and codes inside the vehicle while driving and then I had to use both feet to apply the breaks in order to get the car to stop in the emergency lane on the road as we were driving. No other warning signs or messages prior to this happening everything happened all at once. Had Onstar run diagnostics on the vehicle and 2 codes came back a U1610 Communication code of the vehicles network. The network provides a link between the systems inside the vehicle and when interrupted a code can be established. Service within 7 days. Also code U1639 same description. I had the vehicle towed to the dealer and they advised there was a module that required a further update from when I had my vehicle in on 9/2 for an oil change”

“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.”

“On September 2, 2026, at approximately 3:19 PM, my 2025 Chevrolet Equinox EV unexpectedly applied hard automatic braking while I was proceeding through a green intersection. A white SUV ahead of me was moving to the left and clearing my travel path. There was no vehicle, pedestrian, bicycle, or other obstacle directly blocking my lane that required emergency braking. At the exact moment the vehicle applied the brakes, a Forward Collision Warning appeared on the driver display. Based on the warning and the braking response, I believe the Forward Collision Alert/Automatic Emergency Braking system falsely detected an imminent collision and activated unnecessarily. The unexpected braking created a risk that a vehicle behind me could rear-end my vehicle. My two children were passengers and were frightened by the sudden braking. No collision or injury occurred. There were no warning lamps, messages, or symptoms before this incident. The Forward Collision Warning appeared only when the unexpected braking occurred. The problem has not yet been reproduced or confirmed by a Chevrolet dealer. The vehicle has not yet been inspected by the dealer, manufacturer, police, or…”
