2024 Chevrolet Equinox Powertrain (other) Problems

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 transmission lurches and shakes violently when under pressure such as times when trying to accelerate onto a highway. I recently was traveling and had to enter numerous highways and each time the transmission was extremely jerky and I felt it may fall out of the car at some points. Once I was trying to get on to the highway and a tractor trailer was coming up behind me and I literally have to pull off to the right because the car would not accelerate and was jerking violently. I've had it to Chevrolet service three times and each time they tell me it's normal which I know is absolutely not true.

My 2024 Equinox was returned to the dealership on approximately October 1, 2025, due to a check engine light related to the torque converter. I required a rental vehicle during this time. I picked up my vehicle on October 10, 2025, and all repairs were covered under my extended warranty. I was informed that my rental reimbursement would be issued once I submitted the required paperwork. My safety and the safety of my grandchildren were put at risk loss of power and control-stalling, in ability to accelerate in traffic, gear slippage and over heating Given the known history of torque converter issues in the Equinox—dating back as early as 2005—it is disheartening that GM continues to sell vehicles at premium prices while failing to properly support the customers who purchase them.

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.

To Whom It May Concern, I am writing to formally report a serious and recurring safety issue with my 2024 Chevrolet Equinox, and to request immediate investigation and resolution. The vehicle has, on multiple occasions, unexpectedly gone into “reduced power” mode (also referred to as “limp mode”), drastically limiting acceleration while driving at full speed in traffic. This most recently occurred while my teenage daughter was behind the wheel, causing the car to completely shut off in the middle of the street. The first time this happened, I was traveling at approximately 55 mph on Highway 74 when the vehicle suddenly decelerated to about 35 mph without warning, despite my attempts to accelerate. The check engine light appeared only after the power loss. We narrowly avoided a serious crash. We had to engage hazard lights, swerve through traffic, and coast the vehicle home. The dealership was unable to replicate the issue during follow-up visits, and the issue stopped temporarily—but has now returned. This is more than an inconvenience; it is a critical safety risk to myself, my family, and others on the road. Details: Vehicle: 2024 Chevrolet Equinox Issue: Sudden power loss while driving; engine enters limp mode without warning Occurrences: Multiple (including full vehicle shutdown) over the course of ownership Dealership Response: "No issues found" – despite multiple visits Diagnostic Error: Dashboard reads “Engine Power is Reduced” Concern: Loss of power at high speed, dangerous stalling in traffic

The biggest issue is last year while driving on 74 in busy traffic, the car automatically went into a "low power" mode and limited the power without warning. So now in traffic driving 55 mph, the car drastically slowed to about 35 without warning. It would not go faster no matter what I did. Then the check engine light came on afterwards. Thankfully I made it home safely after turning on my hazards and swerving through heavy traffic. I took it to the dealership and they didn't find any issues... of course. It did it again I took it back. They didn't find anything and then it stopped. Now fast forward today... my daughter drove to the store and the car cut off in the middle of the street. The way she explained it to me it was similar to what happened before. Except it cut all the way off this time. Same error on dash something like, "switched to low power." So I'm panicking. My husband and I go down and I try to start, it wouldn't start a few times. But eventually it did then cut off. Then it cut on when I kept slightly on the gas like I know to do with an older car. So... long story long... I got us home but with limited power and hazard lights. I'm glad we made it home safely and my daughter was shook up but she's safe. I'm terrified to let anyone else in the car let alone drive it. It could've been deadly.

Traveling on the highway with a speed limit of 70 mph. Vehicle would not accelerate above 35 mph resulting in the potential to be rear ended and cause an accident. After three attempts by the GM dealership to repair the vehicle this condition still exists. I have decided due to safety concerns to not operate this vehicle.
