Owners of certain Jeep Wrangler and Jeep Gladiator vehicles should be aware of a significant safety defect affecting more than one million vehicles across North America. Chrysler (FCA US LLC) has announced Recall 21D (NHTSA Campaign Number 26V-363) involving certain 2021-2025 Jeep Wrangler and Jeep Gladiator models due to a defect in the electric hydraulic power steering pump (EHPSP) wiring system that could potentially lead to a vehicle fire.

What Is the Problem?

According to FCA US, under certain conditions, high-resistance electrical activity can occur at the connection point of the Electric Hydraulic Power Steering Pump (EHPSP). This increased electrical resistance can generate excessive heat, causing nearby combustible materials to overheat and potentially ignite.  What makes this defect particularly concerning is that a fire could occur even when the vehicle is parked and the ignition is turned off.

The issue originates from the electrical connection between the EHPSP and its wiring harness. Investigators discovered that some EHPSP components were manufactured outside specified tolerances, which could result in poor electrical contact. Over time, this can create excessive resistance, heat buildup, melting of the connector, and in rare cases, a vehicle fire.

Warning Signs Drivers May Notice

Before a failure occurs, some owners may experience symptoms related to the power steering system, including:

• Loss of power steering assist
• A “Service Power Steering” warning message
• Diagnostic Trouble Codes (DTCs) related to the steering system

However, FCA notes that some incidents occurred without prior warning, which is one reason the recall was issued.

How the Investigation Unfolded

The road to this recall began in May 2023 when FCA US launched an investigation into reports of engine compartment fires in Jeep Wrangler and Gladiator vehicles. After reviewing available data through April 2024, the company initially closed the investigation, determining that the occurrence rate was low and did not represent an unreasonable safety risk.

That assessment changed in August 2024 when FCA began receiving an increased number of reports involving fires originating near the EHPSP electrical connection.  Shortly afterward, on September 6, 2024, the National Highway Traffic Safety Administration (NHTSA) opened a formal investigation, designated PE24-024, into engine compartment fires involving 2021-2023 Jeep Wrangler and Gladiator vehicles.

Over the next 18 months, FCA and NHTSA worked extensively to determine the cause of the fires. Engineers analyzed field reports, inspected returned parts, conducted vehicle buybacks, performed CT scans and X-ray analysis, tested materials, and carried out extensive laboratory and vehicle testing.

In spring 2025, investigators identified manufacturing tolerance issues in the EHPSP connector assembly. These issues could cause excessive insertion forces during assembly, resulting in spread terminals, incomplete electrical connections, and elevated electrical resistance. FCA also identified a separate “terminal push-out” condition that could contribute to poor electrical contact.

Although engineers initially struggled to duplicate the exact failure mode, FCA confirmed in April 2026 that a loose EHPSP electrical connection could generate enough heat to melt the connector and potentially ignite surrounding materials.

By May 2026, FCA was aware of:

• 72 field reports related to the issue
• 63 customer assistance records
• 12 additional service records potentially related to the defect
• 1 reported injury potentially associated with the condition

No accidents related to the defect had been reported.  

Based on the findings of the investigation, FCA’s Vehicle Regulations Committee formally determined on May 28, 2026, that a safety defect exists in affected vehicles.

What Should Owners Do?

FCA US is advising owners of affected vehicles to park their vehicle outside and away from structures, garages, and other vehicles until the recall repair has been completed.  This recommendation reflects the possibility that an electrical overheating event could occur even when the vehicle is parked and turned off.

Dealers will inspect the EHPSP connection and replace affected components as necessary at no cost to vehicle owners.

Owner notification letters are expected to begin mailing on July 9, 2026.

Recall Information

• FCA Recall Number: 21D.
• NHTSA Campaign Number: 26V-363.
• Vehicles Affected: Approximately 1,076,999.
• Defect: EHPSP electrical connection overheating.
• Risk: Potential vehicle fire, including while parked.
• Remedy: Inspection and replacement of affected parts as necessary.

If you own a 2021-2025 Jeep Wrangler or Jeep Gladiator, it is important to monitor recall announcements and schedule the repair as soon as it becomes available. While the number of reported incidents remains relatively small compared to the number of vehicles on the road, the potential consequences of an under-hood fire make this a recall that should not be ignored.
