I was on a road trip and halfway through my check engine light came on and notified me that engine power was reduced while on a 70mph highway. My car the slowed itself down to not exceed 45 then 25mph. I was in a remote area and very far away from a Chevy dealership. I was forced to drive for a long distance to make it to a Chevy dealership that was willing to work with me. Come to find out my fuel pump failed and the car is only 2 years old with only 58,000 miles. This same issue happened a few months ago and I was told by my dealership that it was just update codes required by Chevy that did not update correctly. I've had several other issues like this and have been told it's because the new cars are "basically giant computers". This car also got a new battery after one year because they stated a faulty or crappy manufacturer battery they put it went bad. …

As I was parked with the car running, my 2024 Equinox suddenly shut down and the check engine light came on. I tried to start it, but it didn't. Someone tried to jump the battery, thinking it was that, but it wasn't. I had it towed to the dealership and after 2 days they said the Fuel Pump Power Control Module needed to be replaced. Unfortunately, GM did not have the part, but the dealership found one in another state and we had to wait several days for it to be mailed to them. After a week, once the part was replaced, they tried to start the car and realized that the original issue fried the battery, so they had to replace that as well. I was told that they had seen several customers with the same issue and wouldn't be surprised if GM eventually issues a recall. They also said they couldn't be sure the replacement part wouldn't have the same issue. …

At 5 am in the morning the car suddenly failed and indicated it was an engine or transmission failure in the middle of a four lane major intersection in a downtown area. It was dangerous due to the darkness, and poor visibility. I had to abandon the vehicle as it was dangerous to stay with it while waiting for police. I could have been injured (as could others) due to its sudden failure in the intersection of a busy roadway. Chevrolet dealership states it is the fuel pump driver module. The car is currently at the dealership for repair. There were no warning lamps, messages or other symptoms of the problem prior to the failure until the car suddenly lost power. Once it lost power the engine light lit up and shortly after I had exited the vehicle, I began receiving messages from "On Star" telling me that there were engine or transmission problems. …

Started into traffic and vehicle quickly slowed way down and then started to move again. At next light power lost again. Do not remember if warning light came on but it was not there prior to the incident. Towed to dealer. Fuel pump replaced. One month later accelerating to exit in heavy traffic it lost power. Engine light came on saying something to the effect engine power lost. It Started back up quickly and I got safely where I was going. It was running ok so I finished another 400 miles of trip. Dealer service tech on phone said probably stabilizer did what it's suppose to do and probably avoided something serious. Not too much driving since then but I can tell I don't have the pick up I should have when accelerating. Afraid each time I give pressure to the pedal that it might stall again as it doesn't pick up speed as I've been used to. …

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. …

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. …

While the vehicle was in park and still running it started sputtering and idling erratically and the engine shut off. While trying to restart, the car was having a hard time starting, eventually starting with the same problem. While driving, the car was sputtering, had reduced engine power, and felt like it was going to shut down. The check engine light was on the entire duration of the incident. This has been a recurring intermittent problem that first occurred approximately three months ago. Car has been to the dealer before but the problem didn't occur and they were unable to diagnose the issue. When taking the car to the dealership on 09 March, the dealer confirmed the problem and said it was a faulty fuel pump that will cost over $800 to repair. …
