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.

The engine failed while driving on the highway on two separate occasions due a fuel pump issue. The first time it happened, it was just reduced power (could only drive maybe 40 miles an hour). I brought it to the dealership and they said that General Motors told them it needs a software update which they completed. However the second time it happened (4 months later) it was full engine shutdown in the left lane on a 65mph highway with my family (including my toddler) in the car. The first time it happened we were able to make it home by driving with the hazard lights on very slowly. But the second time we were doing the 65 mph speed limit in the left lane on a 3 lane highway. To avoid causing a pile up of cars or a deadly accident, we had to use the momentum of the speed we were going to try to safely drift across three lanes of congested traffic just to make it safely to the shoulder. We were then stuck on the side of the highway in the sun on an 80 degree day with a car with no power. I had to remove my two year old from the car so he didn't get heat exhaustion and stand on the side of the highway holding him in the little bit of shade we could find. The car then had to be towed back to my dealership over an hour away because it would not even turn on. The dealership was not able to replicate the issue the first time it happened, but did the software update that the manufacturer recommended. To my knowledge its only been inspected by the dealership. The only warning signs/messages/lights were the ones happening as the engine was failing/shutting down. There was no advanced warning. This care is less than two years old and its a leased vehicle from the dealership down repairs, I work from home there are less than 20k miles on i, this is not neglect on my part or over usage in anyway of the vehicle.

Vehicle Safety Complaint – 2024 Chevrolet Equinox I am reporting a safety defect involving unintended vehicle movement and improper shutdown behavior. While operating my 2024 Chevrolet Equinox, I was able to shut the vehicle off even though it was not in Park. After shutdown, the vehicle rolled forward on its own and struck a tree. At the time of the incident, the radio remained on despite the vehicle being turned off, indicating the vehicle may not have fully entered ignition-off state. This incident suggests a potential malfunction involving one or more of the following systems: gear position detection system transmission park engagement mechanism electronic shift control module ignition state logic or body control module The vehicle should not allow shutdown unless it is in Park, or it should provide clear warnings and prevent unintended movement. This behavior presents a serious safety risk of rollaway incidents. I am requesting a full diagnostic inspection and documentation of all stored fault codes, including history codes, prior to any resets. Please also check for software updates, technical service bulletins, or known defects related to shift position recognition or ignition state control. This issue resulted in unintended movement and property damage and poses a significant safety hazard.

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. Meanwhile I stood in the pouring rain in an unsafe neighborhood, leaning out into traffic to try and stop cars from running head on into my car for over 30 minutes waiting for police.

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. I did some research and found that GM has had this issue with 2019 - 2024 vehicles. Some customers reported that they were driving and almost got hit by other vehicles when theirs shut down. My car only had 18000 miles when this occurred. I no longer feel safe driving my car.
