The fuel pump quit while driving, fortunately we were not on as interstate highway. I was able to coast to the side of the road and call for tow. If this occurred on an interstate highway it could have been very dangerous. The dealer repaired the vehicle under a warranty. The fuel pump and control module were replaced.

Earlier that morning the cluster displayed "Service Power Steering - Drive With Care" at 12,925 miles. I photographed it at a traffic light. The vehicle drove normally on that leg, steering assist was not lost, and I dismissed the notification, which cleared. I parked. On restarting a short time later, the vehicle went into failure mode. While driving on surface streets it lost power steering assistance three separate times in about eight minutes. The first was mid-turn: the wheel became substantially harder to turn and required significantly increased force to complete the corner. The second was on a main road. The third was as I turned into a dealership lot. Between those events, on two separate occasions, the vehicle continued propelling itself forward with my foot off the accelerator. It did not coast or decelerate as normal when I lifted off. Multiple warnings illuminated across the cluster and stayed lit. I photographed and recorded video showing "Service High Voltage System" and "Service ESC" at 12,942 miles. I judged the vehicle unsafe and drove directly to the nearest dealership, about eight minutes away, and surrendered it. I was on surface streets with traffic, cyclists and pedestrians. Loss of steering mid-turn plus a vehicle that would not stop propelling itself put me and others at risk. At highway speed, or with passengers, I do not believe I could have maintained control. The dealership confirmed the failure and reported an initial diagnosis of a burned out drive motor power distribution control module. Teardown is pending. The vehicle remains out of service and is available for inspection. The three losses of steering assistance remain unexplained. My understanding is that electric power steering is separate from the failed propulsion module, and the steering warning appeared before the module failure. UNKNOWN whether these were related or separate concurrent failures. Manufacturer has not inspected. No crash, no injuries, no police report.

Wheat attempting to enter 40mph traffic from a side street stop sign the Equinox did not accelerate and the engine stopped. There was no warning of a problem. The car would not start and I received a message the a p129f error was detected and it was a critical error. It also said !fuel management system schedule service now. I also received a text that said "Diagnostic alert: Service the engine and transmission system in your 2024 Equinox immediately." I waited 3 hours for a tow and the car was taken to the local Chevrolet dealership where it was serviced. My grandson was with me at the time. I felt fortunate this did not happen while on the highway, or while pulling into the traffic. The fuel module was replaced. I was assured it was replaced with the newest module and computer updates. I am very concerned this will happen again based on what I have read. The car milage was 17,537 when the failure occurred and was covered under warranty.

My car broke down on me in the middle of a highway on my way to work yesterday with no warning it just died and I had to roll in between the island of the road, but I was blocking off traffic and my side of the car was still in the way of people coming up behind me. It wouldn’t start over. It was extremely hot outside and trucks tractor trailers and cars were flying up behind me, the speed limit on that road is 50 but people go between 65 70 miles an hour on that road so it was extremely scary and I was shaken up and was trying to think of how to fix the situation cause I had to call Work and tell them that I was down the road, broken down and two firetrucks stopped because they saw me and thankfully pushed me out of the way, and then my boss came for me to sit in the air conditioner while I figured out getting a tow I had it towed to the dealership I bought it from. ironically that morning I had a diagnostic email sent to me and everything was perfectly fine on it. onstar all of a sudden when the car shut down on me, it gave me a code of p129f. I also received an email at that time from OnStar that my fuel system was down. I called the dealership and told them that the car was coming to them. They ended up calling me back and telling me that it was the fuel pump and that it’s known for breaking down because GM apparently knows that there was something wrong with the fuel pumps in these cars. When I bought the car brand new after driving it, I had mentioned to the car dealership that it felt like it was lagging, and when they looked at it, they said it was fine. There was nothing wrong with it. I feel like this was kept for me that this could’ve been an issue and that I should’ve been sent a letter from GM knowing that I have the year making model of these cars that tend to have these issues that my fuel pump should’ve been replaced or looked at because I was putting a very extremely dangerous situation yesterday .

Subject vehicle has 11919 miles. The vehicle is less than three years old and covered under factory warranty. While driving 35MPH, engine suddenly did not respond to throttle. This engine stopped. Driver was able to coast to roadside. After OnStar analysis, engine control computer logged code 'P129F - An issue has been detected in the Fuel Management System used to maintain, control and monitor fuel consumption'. After towing to dealer, part number 13554821 was replaced. There were no prior warnings. The engine just stopped and would not restart. This is a major safety concern. This incident occurred 10 minutes after exiting the highway (65MPH). Having your engine stop unannounced at any speed in traffic is not safe, especially in high traffic and high speed situations. Dealer service nevertheless indicated this particular problem and part is well known but not considered a safety issue by the manufacturer. We disagree.
