2025 Chevrolet Equinox: sudden loss of power

Filed May 27, 2026 · Acceleration, Engine · CT

While driving my 2025 Chevrolet Equinox, the vehicle experienced a sudden power and drivability issue. The vehicle began to decelerate on its own while in motion, even though I was actively driving. A warning notification appeared on the driver dashboard, and shortly after, the vehicle power shut off. This creates a serious safety concern because the vehicle can unexpectedly lose speed and/or power while driving in traffic. The issue appears to involve the transmission, powertrain, or vehicle electrical/power management system. The loss of acceleration and sudden deceleration could increase the risk of a crash, especially at highway speeds or in heavy traffic. This incident occurred while the vehicle was being driven, not while parked. The warning message appeared on the dash before or during the power loss. I am reporting this because the vehicle’s sudden deceleration and power shutdown while driving could be a safety defect. I am requesting that the federal safety agency review whether this issue is related to a known defect, recall, transmission issue, powertrain control issue, or electrical system failure affecting the 2025 Chevrolet Equinox.

The vehicle is currently at the dealership for inspection, The vehicle completely shut down while I was driving on Florida’s Turnpike, creating an extremely dangerous situation on a high-speed highway. There was no warning prior to the shutdown, and I am currently pregnant, which made the situation especially traumatic and heightened the risk to both myself and my unborn child, as well as other drivers on the road.

I drive 20+ miles each way to work every day. Much of this drive is on highways, and currently the bridge connecting Ohio and Kentucky is down to three lanes with no berm. On a windy road with low visibility and a steep hill near my home, the car completely lost power and acceleration without any warning. I wasn't able to drive it completely off the road before it came to a stop and due to the loss of power was unable to move into neutral to push it and the hazards would not work. Thank God that this didn't take place on the bridge or with my family in the car. I made the decision to exit the car while it was still on the road and find a safe area in the grass where I could call for help. When I exited the vehicle, it locked me out and the only way to get in was through the driver's side door, which would put me back on the road in traffic and at risk. The electrical failure prevented me from opening the other doors. The car's complete system failure put my safety/life at risk and could jeopardize the lives of others if it wasn't investigated. To make matters worse when the tow truck came via OnStar they weren't equipped to move a car stuck in park or drive due to the electronic gear shift so they drug it with the tires locked onto the bed. After several days of testing the electrical system, the dealership found a loose wire and informed me that it had been fixed. I picked up the car and after a mile or so, the check engine light came on. I contacted the dealership to come pick it up and that's where it stands at the moment. My intention was to pass this on to my boys when they start driving, but this experience will alter that plan.
