2025 Chevrolet Equinox

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 NHTSA 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 contact owns a 2025 Chevrolet Equinox. The contact stated while driving at an undisclosed speed, the transmission independently shifted into neutral. No warning light illuminated. The vehicle lost motive power. The contact stated that the vehicle stopped in the middle of a busy road. The contact stated that while attempting to start the vehicle, the vehicle started. In addition, the contact stated that the failure was persistent. In addition, the contact stated that later the check engine warning light illuminated. The vehicle was taken to the dealer, however the vehicle had not been inspected. The manufacturer was not made aware of the failure. The failure mileage was approximately 24,000.

While in a parking lot going about 10mph or less, a car pulled out from a parking space on the left. I did a full brake and despite being dry, warm pavement, the car activated abs and released some brake pressure and allowed the car to continue to move. This ment that my braking distance increased by about 5-10 feet more than you'd expect. I have had this happen 3 times, each time a car was pulling out perpendicular on the left. I tried to replicate this in an open parking lot and it never repeated therefore I think it has something to do with the car approaching on the left and the active braking system.

This vehicle makes a noise that sounds like your driving over rumble strips. The front end shakes and there is a hard vibration. I purchased this vehicle used on 5/5/26 and it’s been in the dealership twice already. The Onstar module is defective and now this noise and vibration. The shaking starts upon accelerating. The dealership, Central GMC/Buick of Jonesboro, AR. told me that GM knew about the problems and that their Engineers did know the fix yet. They say it’s not a safety issue but This is an unsafe vehicle and GM knows it’s unsafe. I’m afraid to drive it.

My vehicle OnStar telematic module has shorted out the complete electrical system. This module is backordered. No time frame was told it could be months. Many GM vehicle have the same problem. The vehicle can stop while sitting or driving. This vehicle is unsafe to drive i traded it to the dealership. They will hold on to it until(if & when) they get the part.

The contact owns a 2025 Chevrolet Equinox. The contact stated that the vehicle's GPS monitoring system had failed to operate as needed. The vehicle was taken to the dealer on multiple occasions where the contact was informed that a software update was performed on the vehicle; however, each software update failed to correct the failure. The dealer was notified of the continued failure and informed the contact that the part to repair the vehicle was on backorder with no certain timeframe as to when the part may become available. The contact stated that he and his wife are elderly and rely on the GPS monitoring system for both traveling and unexpected medical emergencies. The manufacturer was also notified of the failure where they gave the contact the same information as the dealer and was given a case number. The vehicle was not repaired. The failure mileage was approximately 22,000.
