If you own a Jeep Wrangler 4xe or Grand Cherokee 4xe, the Jeep 4xe battery lawsuit landscape now includes at least four federal class actions and a growing set of individual claims, all alleging that Stellantis sold plug-in hybrids with fire-prone Samsung SDI battery packs and then failed to fix the problem through repeated recalls. No class has been certified, no settlement has been announced, and no permanent repair is available. Roughly 320,000 vehicles are affected.
What the Lawsuits Allege
The complaints center on the high-voltage lithium-ion battery packs supplied by Samsung SDI, which use a 96-cell configuration with nickel-cobalt-manganese prismatic cells. A joint investigation by Stellantis and Samsung SDI found that certain cells contain “separator damage” — a compromised internal membrane that can trigger an internal short circuit, overheating, thermal runaway, and fire. Fires have occurred in parked vehicles, in vehicles that were turned off, and during charging, not only while driving.
Stellantis reported 19 battery-pack fires and one injury to the National Highway Traffic Safety Administration. Nine of those fires happened in vehicles that had already received an earlier recall software fix, which is the fact the plaintiffs keep returning to: the remedy did not work, and Stellantis eventually admitted as much.
In November 2025, Stellantis issued recall 25V-741, superseding an October 2024 recall after the company acknowledged the earlier software update “was ineffective in detecting certain abnormalities in the battery that can lead to a fire.” That November 2025 recall covers 320,065 vehicles. No remedy was available when the recall was issued, and none had been implemented as of mid-2026. NHTSA and Stellantis told owners to park outside, away from structures and other vehicles, and to stop charging.
The Class Actions
Four federal class actions are active. A fifth was reportedly filed in New York federal court on March 4, 2026, but details are not publicly available.
Frisch v. FCA US LLC (Eastern District of Michigan)
This is the class action focused squarely on the battery fire defect. It’s pending before Judge Brandy R. McMillion as Case No. 2:24-cv-10546. Lieff Cabraser filed a Second Amended Complaint on November 25, 2024, asserting a nationwide claim under the Magnuson-Moss Warranty Act along with breach of implied warranty, unjust enrichment, and consumer protection claims under the laws of roughly 20 states. Lieff Cabraser has said it is no longer accepting new plaintiffs in this case.
Humphreys v. FCA US LLC (District of Utah)
Lisa and Jaron Humphreys, owners of a 2023 Wrangler Unlimited Sahara, filed a proposed class action on January 21, 2026, as Case No. 2:26-cv-00053. The complaint alleges that the Samsung-made battery packs contain internal defects that create fire risk even in parked, powered-off vehicles, and that Stellantis concealed known defects while issuing recalls in 2023, 2024, and 2025 that never fixed the problem. The Humphreys seek to represent all affected 4xe owners and lessees nationwide. Head Law, PLLC and Janove PLLC represent them. The case is pending.
Detroit Federal Court Action
Sixteen named plaintiffs filed suit on behalf of a proposed class on April 24, 2026, in U.S. District Court in Detroit. The complaint alleges Stellantis “understated the nature of the defects” and was “unable or unwilling to remedy the fire risk defect,” and that prior recall remedies were ineffective. The plaintiffs seek financial damages and attorneys’ fees. Stellantis declined to comment.
Crowell v. FCA US LLC (District of Delaware)
The earliest case, Case No. 23-cv-00013, was filed in January 2023 and targets a different defect: the “Fuel and Oil Refresh Mode” cycle, which plaintiffs say engages too often and too long, particularly in cold weather, preventing electric-only operation. If your concern is the fire risk, Frisch, Humphreys, and the Detroit case are the ones tracking that issue. Judge Maryellen Noreika denied most of Stellantis’s motion to dismiss in September 2024, and Keller Rohrback represents the plaintiffs.
None of these proposed classes has been certified, and no settlement has been announced in any of them.
Individual Lemon Law and Product Liability Claims
Owners aren’t limited to waiting on a class. Individual lemon law and product liability claims are moving in parallel. The most visible is Phillips v. FCA US LLC, Case No. 1:23-cv-00251, filed in the District of Delaware by PJ and Carley Phillips of Monroe, Michigan. They leased a 2023 Grand Cherokee 4xe that allegedly needed hybrid-component repairs at 10 and 12 miles on the odometer, later developed glitches in navigation, backup cameras, crash detection, and steering, and lost power entirely at 70 mph on I-75 in May 2025.
The family went through two arbitrations. The first, in April 2024, sided with FCA. After the highway shutdown, a second arbitration ruled for the family, and a Michigan judge vacated the original arbitrator’s ruling, opening a path to a jury trial. The case was referred to mediation in late 2024 and moved into discovery in 2025. As of May 2026, no trial date has been set, and Stellantis’s motion to dismiss is still pending.
At least one owner has reported a garage fire caused by a 4xe battery failure, with insurance coverage denied and significant out-of-pocket costs. That risk to the home, not just the vehicle, is part of what individual claims are trying to reach.
Which Vehicles Are Covered
The November 2025 recall covers 2020–2025 Jeep Wrangler 4xe and 2022–2026 Jeep Grand Cherokee 4xe models, totaling 320,065 vehicles. Stellantis has discontinued the Wrangler 4xe, Grand Cherokee 4xe, and Chrysler Pacifica plug-in hybrid in North America, and a stop-sale order prevents dealers from selling remaining 4xe inventory. Selling a vehicle under the stop-sale carries a fine of up to $27,874 per unit.
What Owners Should Do Now
The safety guidance from Stellantis and NHTSA is direct: park outside, away from structures and other vehicles, and do not plug in to charge. Symptoms owners have reported short of fire include unexpected power loss while driving, charging failures, dashboard warning lights, and unusual noises from the battery area.
Stellantis had projected a repair remedy for the second quarter of 2026. As of mid-2026, no fix has been confirmed. If you want in on a class action, Frisch is not accepting new plaintiffs, but the Humphreys case in Utah and the Detroit case filed in April 2026 both seek nationwide classes and remain open. If your vehicle has already caused you specific losses — repeated failed repairs, a fire, denied insurance, loss of use — an individual lemon law or product liability claim runs on its own track and doesn’t depend on a class being certified.
