GM Equinox Terrain Fuel Pump Lawsuit: What Every Owner Needs to Know
If you own a 2020-2024 Chevrolet Equinox or GMC Terrain, your vehicle may have a defective fuel pump that could cause sudden stalling, loss of power, and dangerous driving conditions—and General Motors has been accused of knowing about the problem for years without providing a permanent fix.
A class action lawsuit filed in May 2024 alleges that GM knowingly sold these SUVs with faulty fuel pumps or fuel pump power control modules that fail prematurely, often before 100,000 miles, even though these components are designed to last between 150,000 and 200,000 miles. The lawsuit, officially titled Kerr et al. v. General Motors LLC, represents thousands of affected owners across the United States and claims that GM has concealed the defect, issued ineffective recalls, and left drivers to bear the cost of repeated repairs.
1. What the Lawsuit Alleges Against GM
The class action lawsuit, filed in the U.S. District Court for the District of Delaware, makes several serious claims against General Motors:
GM knew about the defect since at least 2019. According to court documents, the automaker was aware of the fuel pump problems before many of these vehicles were even sold to customers. Despite this knowledge, GM continued to market the Equinox and Terrain as "safe, durable and reliable" vehicles, allegedly concealing the defect from consumers.
The fuel pump recall didn't fix the problem. In February 2023, GM issued recall campaign 23V013 (GM number N222372310) covering approximately 23,000 model year 2021-2022 Chevrolet Equinox and 2022 GMC Terrain vehicles. Dealers were instructed to replace the defective ACDelco fuel pump modules at no charge. However, plaintiffs allege that GM simply replaced faulty parts with identical, equally defective components, leaving owners waiting for their "fixed" vehicles to break down again.
The recall didn't cover all affected vehicles. The lawsuit claims that the recall should have included 2020-2024 model years, not just the 2021-2022 models that GM acknowledged. This means thousands of owners with defective fuel pumps were left without any free repair option.
GM has no permanent solution. The lawsuit states that "GM knows there is no permanent repair for the Defect, yet GM continues to direct its authorized dealerships merely to replace certain components with equally defective replacement components while informing consumers that their vehicles are fixed". This creates an endless loop of failures and repair costs.
2. Common Symptoms of the Fuel Pump Defect
If you own a 2020-2024 Chevrolet Equinox or GMC Terrain, watch for these warning signs that indicate a failing fuel pump or fuel pump control module:
Audible ticking noises coming from the rear of the vehicle, near the fuel tank. This is often one of the earliest indicators of a problem.
Engine hesitation and sputtering during acceleration, especially when you need power to merge onto highways or pass other vehicles.
Sudden stalling while driving, which can happen without warning and at any speed. This is the most dangerous symptom because it can lead to loss of motive power and increase the risk of a crash.
Difficulty starting the engine or complete inability to restart after the engine has been running. Some owners report that their vehicles simply refuse to start, leaving them stranded.
Decreased engine performance and worsened fuel economy. When the fuel pump cannot deliver consistent pressure, the engine struggles to perform efficiently.
Dashboard warning lights may illuminate, and diagnostic trouble codes such as P0089 (fuel pressure not at specification), P0191 (abnormality in fuel pressure readings), P0300 (random misfire), P228C (fuel pressure too low), and P2635 (fuel pump flow performance) may be set.
3. Real Stories from Affected Owners
The lawsuit was brought forward by three plaintiffs whose experiences illustrate the frustration and danger that Equinox and Terrain owners face:
Greg and Twila Kerr purchased a pre-owned 2021 Chevrolet Equinox in October 2022 with approximately 32,000 miles. They properly maintained the vehicle according to GM's recommended schedule. When the Equinox reached 40,000 miles around March 2023, they noticed it had trouble starting. Greg Kerr contacted his dealership but was told "there was nothing the dealership could do until the vehicle died completely". When they contacted another dealership for a replacement pump, they were told replacement parts were out of stock. The dealership confirmed that GM had recurring issues with fuel pumps. The Kerrs ultimately had to buy a replacement pump from an independent supplier and repair the car themselves.
Robert Knowles purchased a new 2023 GMC Terrain in May 2023. Within just three months and only 5,500 miles, the Terrain began experiencing engine hesitation, stalling, and unusual noises. Knowles brought the vehicle to a dealership, where technicians claimed to have repaired it. By October, the problems returned. He brought it back again, and the dealership purported to repair it once more, but the issues remained. In March 2024, with 44,000 miles on the odometer, the dealership confirmed the fuel pump was the cause but still did not repair the vehicle. As of the lawsuit filing, Knowles was still waiting for GM to provide a permanent fix.
4. The Cost of Fuel Pump Repairs
Replacing a defective fuel pump or fuel pump control module is not cheap. According to the lawsuit, out-of-warranty replacement costs range from $1,200 to $2,000. This is a significant expense for any vehicle owner, especially when the replacement part is likely to fail again.
The lawsuit argues that GM has effectively shifted the cost of repairs from the manufacturer to unsuspecting consumers. By concealing the defect and failing to provide a permanent solution, GM forces owners to pay for repeated repairs out of their own pockets.
Additionally, the lawsuit claims that the defect reduces the resale value of affected vehicles. Because GM has no real repair solution, potential buyers are wary of purchasing used Equinox or Terrain models, and owners who try to sell their vehicles face lower offers.
5. How the Fuel Pump System Works and Why It Fails
To understand why this defect is so problematic, it helps to know how the fuel system operates in these SUVs:
The fuel pump, manufactured by GM subsidiary ACDelco, is located inside the fuel tank. It draws fuel from the tank and sends it under pressure to the engine through fuel lines.
The fuel pump control module sets the pressure limit for the fuel and electronically controls the pump's operation. It communicates with the engine control module to deliver the appropriate amount of voltage so the pump can draw the right amount of fuel.
The engine control module tells the fuel pump control module when to start the pump and continuously communicates the engine's fuel flow needs.
When the fuel pump or control module fails, the flow of gasoline from the tank to the engine is interrupted. Without enough fuel, the engine cannot operate properly, leading to hesitation, stalling, loss of power, and potential engine damage.
One particularly concerning aspect of this defect involves GM's Stop/Start technology. When the vehicle idles at a stoplight, the system shuts off the engine to save fuel. The engine control module tells the fuel pump control module that fuel is not needed and turns off the pump. When the driver releases the brake, the system should restart the engine and the fuel pump. However, the defect puts these vehicles at risk of failing to restart, leaving drivers stranded at intersections.
6. GM's Response to the Lawsuit
General Motors has fought back against the class action, filing a motion to dismiss in 2025. The automaker argues several points:
No common defect. GM claims the plaintiffs fail to show that all 2020-2024 Equinox and Terrain vehicles share a common fuel pump problem. The company argues that simply defining the defect as "fuel pumps and/or fuel pump power control modules that fail or operate intermittently" is insufficient to demonstrate how GM could have known about or fixed the particular issues in each vehicle.
No nationwide class. GM contends that nationwide class action claims cannot proceed because state laws vary too widely. The automaker points out that different states have different standards for proving fraud—some require "reckless disregard" while others require "actual knowledge of falsity," and some require proof "by clear and convincing evidence" while others accept a "preponderance of the evidence".
Warranty issues. GM argues that the plaintiffs' warranty claims fail because they did not seek repairs during the 3-year, 36,000-mile warranty period. The Kerrs' Equinox had 40,000 miles when problems first appeared, and Knowles' Terrain was also outside the warranty window for some of its repairs.
Fraud claim challenges. In November 2025, GM filed a motion to dismiss the fraudulent inducement claim, arguing that the plaintiffs admit GM issued service bulletins and recall notices to fix fuel pump problems. GM states it never promised its vehicles would be defect-free, only that dealers would repair defects within the warranty period.
Despite these arguments, as of mid-2025, the case remained active with discovery ongoing and no settlement reached. The court had not yet ruled on class certification.
7. What This Means for Equinox and Terrain Owners
If you own a 2020-2024 Chevrolet Equinox or GMC Terrain, here is what you need to know:
Check if your vehicle is covered by the recall. You can visit NHTSA's website at www.nhtsa.gov/recalls and enter your Vehicle Identification Number (VIN) to see if your vehicle is part of the February 2023 recall. However, keep in mind that the recall only covers 2021-2022 Equinox and 2022 Terrain models—not the full 2020-2024 range that the lawsuit alleges is affected.
Document any problems you experience. If your vehicle shows symptoms of fuel pump failure, keep detailed records of when the issues occur, what symptoms you observe, and any diagnostic trouble codes that appear. Save all repair receipts and correspondence with dealerships.
Be aware that replacement parts may fail again. Even if you receive a free replacement under the recall, the lawsuit alleges that GM installs equally defective parts. Some owners report needing multiple repairs for the same issue.
Consider joining the class action. If you purchased or leased a 2020-2024 Chevrolet Equinox or GMC Terrain in the United States, you may be part of the proposed class. The lawsuit seeks compensation for out-of-pocket repair costs, diminished vehicle value, and other damages.
Contact a lemon law attorney. If your vehicle has been in the shop multiple times for the same issue, you may have lemon law protections depending on your state. Some owners have already pursued individual lemon law claims.
8. The Broader Context: GM's History with Fuel Pump Defects
This is not the first time GM has faced legal action over fuel pump problems. A separate settlement, known as the Chapman v. General Motors LLC case, reached final approval in May 2025 and involved defective CP4 fuel pumps in 2011-2016 Duramax diesel Chevrolet Silverado and GMC Sierra trucks. That settlement provided $50 million in compensation to affected owners in California, Florida, Illinois, Iowa, New York, Pennsylvania, and Texas.
The current Equinox and Terrain lawsuit involves a different fuel pump system, but the pattern is similar: GM allegedly knew about the defect, failed to disclose it, and provided inadequate repairs.
Additionally, GM has faced other recalls and lawsuits related to oil consumption defects in older Equinox and Terrain models (2010-2017), where low-tension oil rings caused excessive oil burning, engine knock, stalling, and engine failure. A 2019 settlement covered some of those models, but owners of 2014-2017 vehicles were left out and filed a separate lawsuit in 2023.
9. What to Do If Your Fuel Pump Fails
If you experience fuel pump failure in your Equinox or Terrain, here are practical steps to take:
1. First, confirm the diagnosis. Have a trusted mechanic or dealership run diagnostic tests. Common trouble codes include P0089, P0191, P0300, P228C, P228D, and P2635.
2. Check your warranty coverage. If your vehicle is still within the 3-year, 36,000-mile basic warranty, or if it's covered by an extended warranty or GM's powertrain warranty, you may be eligible for a free repair. However, be aware that even warranty repairs may only replace defective parts with equally defective ones.
3. Document everything. Keep records of all visits to the dealership, including dates, symptoms reported, work performed, and any diagnostic codes. Take photos or videos of warning lights and vehicle behavior if possible.
4. Report the issue to NHTSA. File a complaint with the National Highway Traffic Safety Administration at www.nhtsa.gov. This helps regulators track safety defects and may lead to expanded recalls.
5. Consider a high-quality aftermarket replacement. If you must pay for a repair out of pocket, choose a replacement fuel pump that offers better reliability than the OEM ACDelco part.
