Owners of more than one million Jeep Wranglers and Gladiators now face a stark warning from federal regulators: park outside and away from structures until Stellantis can fix a defect that may cause fires even while the vehicles sit idle. The National Highway Traffic Safety Administration has issued guidance tied to the recall, which covers an electric power steering fault linked to fire risk in parked vehicles. This is not the first time NHTSA has told Jeep owners to keep their vehicles away from garages. A separate, earlier set of recalls targeting Jeep Wrangler and Grand Cherokee plug-in hybrid models carried the same “park outside” directive, raising pointed questions about whether Stellantis has a broader electrical problem running through multiple Jeep platforms.
Repeated “park outside” warnings across Jeep models
The recall covering more than one million Wranglers and Gladiators centers on an electric hydraulic power steering (EHPS) issue that can trigger fires without any driver input. NHTSA has used unusually direct language for this campaign, telling owners to keep affected vehicles outdoors until a remedy is in place. That language is not new for the agency when it comes to Jeep products. NHTSA previously issued an expanded recall for Jeep Wrangler and Grand Cherokee plug-in hybrid electric vehicles over a separate fire risk. The agency confirmed that the PHEV recall and the million-plus Wrangler and Gladiator campaign are distinct actions, meaning two different defect populations within the Jeep brand have independently warranted the same extreme parking precaution.
Before the expanded PHEV recall, NHTSA had already published a consumer alert directing owners of Jeep Grand Cherokee and Jeep Wrangler PHEVs to park outside due to fire risk. That earlier alert, too, was identified as separate from the EHPS-related Wrangler and Gladiator recall. The result is at least three distinct regulatory actions, each involving Jeep vehicles and each carrying the same core safety instruction. For consumers, the practical effect is a growing list of Jeep nameplates flagged for the possibility of catching fire while unattended.
The repetition of “park outside” language across both internal-combustion-adjacent and plug-in hybrid Jeep models is significant. NHTSA does not issue that directive casually. The instruction typically signals that the agency believes the fire risk is high enough to endanger nearby property and people, not just the vehicle itself. When the same warning applies to powertrains as different as a traditional Wrangler and a Grand Cherokee PHEV, it suggests the problem is not confined to a single battery chemistry or engine type.
For Stellantis, the cumulative effect of these actions is reputational as well as technical. Wrangler and Grand Cherokee are among Jeep’s most visible products, and repeated fire-related warnings can erode owner confidence even among drivers whose vehicles are not directly affected. For dealers, the overlapping campaigns create a communication challenge: they must explain that different recalls involve different hardware, even as customers hear the same blunt message to leave their Jeeps outside.
What NHTSA investigation records show about the defect trail
NHTSA’s Office of Defects Investigation maintains a public repository of recall reports, investigation resumes, and supporting chronologies in its document archive. Documents referenced under the designation PE24024 appear in the agency’s investigation materials tied to these Jeep fire-risk campaigns. Those records form the backbone of the regulatory paper trail connecting the EHPS steering defect in Wranglers and Gladiators to the agency’s formal enforcement actions.
The PHEV recalls and the EHPS recall share a common thread in how NHTSA has escalated its response. In each case, the agency moved from initial investigation to public consumer alerts and then to formal recall announcements with explicit parking instructions. That escalation pattern indicates the agency gathered enough field evidence, whether from owner complaints, fire reports, or manufacturer data, to conclude that the vehicles posed an active hazard even when turned off.
What the public record does not yet contain is a detailed root-cause analysis from Stellantis explaining why multiple Jeep platforms are producing fire risks in parked conditions. The PHEV fire hazard and the EHPS fire hazard involve different vehicle systems: one relates to high-voltage battery and charging architecture, while the other involves a steering-assist component and its electrical connections. On the surface, these are unrelated failure modes. But the fact that both can produce fires in stationary, unoccupied vehicles points to potential weaknesses in how Stellantis designs or sources electrical components and wiring for the Jeep lineup.
A shared supplier for wiring harnesses, connectors, or control modules could explain why fire risks have appeared across powertrains that otherwise have little in common. Alternatively, a software or circuit-protection gap in Stellantis’ vehicle electrical architecture could allow faults to generate enough heat to start fires even when the ignition is off. Neither explanation has been confirmed publicly by Stellantis or NHTSA, and the available investigation documents do not name a single root cause spanning all affected models.
Without a unifying explanation, owners are left to interpret a series of technical bulletins and recall notices that can appear fragmented. The EHPS campaign, for example, focuses on a hydraulic power steering unit that can overheat and ignite. The PHEV actions focus on high-voltage components that may short or fail internally. Each notice stands alone, but together they sketch a pattern of electrical vulnerabilities that emerge only after vehicles have been in service and accumulating miles.
Unresolved questions for Jeep owners and Stellantis
Several gaps in the public record leave Jeep owners without clear answers. Stellantis has not disclosed a detailed repair timeline for the million-plus Wrangler and Gladiator vehicles covered by the EHPS recall, beyond assurances that a remedy will be provided at no cost. Owners may face weeks or months of altered routines, parking outside in all weather and weighing whether to continue daily use of their vehicles while they wait for parts and dealer appointments.
It is also unclear how Stellantis plans to prevent similar defects from surfacing in future Jeep models. The company has not publicly committed to a brand-wide electrical audit or redesign effort aimed at addressing common failure points. Absent that kind of forward-looking plan, regulators and safety advocates may continue to scrutinize Jeep products for emerging fire trends, especially as more electrified variants enter the lineup.
For now, the most concrete guidance comes from NHTSA’s own language. Owners of affected Wranglers, Gladiators, and PHEV models are told to park outside and away from structures, monitor recall notices, and schedule repairs as soon as dealers can perform them. That advice is straightforward, but it does not resolve the underlying anxiety that comes with owning a vehicle that federal regulators say could ignite while sitting still.
The broader industry implications are still taking shape. Automakers across the market are layering complex electrical systems onto long-standing platforms, and the Jeep recalls highlight how failures in those systems can create risks that are difficult for drivers to detect in advance. As more investigation documents and technical explanations become public, they may reveal whether Jeep’s experience is an outlier or an early warning about how legacy designs and modern electrification can clash.
Until then, the recurring “park outside” warnings serve as a blunt reminder that the line between acceptable risk and urgent hazard is drawn not in engineering labs, but in the real-world data flowing into NHTSA’s files. For Jeep owners, that line now runs directly through their driveways.
