Jeep is telling more than one million Wrangler and Gladiator owners to park outside, but it has nothing to do with off-roading and enjoying the outdoors. This advisory comes as part of a safety recall, affecting 1.1 million vehicles that could catch on fire. Here's what you need to know. Bad Electrical Connection Can Lead To Heat And Fire JeepNHTSA recall 26V363 applies to Wranglers and Gladiators from 2021 through 2025. A connector in the electric hydraulic power steering pump (EHPSP) is getting the blame. The electrical connection is "susceptible to high resistance." As Jeep describes it, "In some circumstances, high resistance electrical activity may take place in the area of the EHPSP connection causing overheating of combustible materials."High resistance means high heat. High heat in the connector can result in melting insulation and a possible fire. As the NHTSA recall documents so helpfully put it, "a fire can result in increased risk of occupant injury and injury to persons outside the vehicle." At least that much is clear.Taking a closer look at the recall, it applies to 787,887 Jeep Wranglers from model years 2021-2025, with all gas and diesel engines affected, including 4xe plug-in hybrid models. As for Gladiator, it covers 289,112 pickups of the same model years, also including all models.This isn't corrosion in a connector or a fluid leak, both of which we've seen result in safety recalls in other vehicles. Here, affected connectors with no visible damage are at risk of a fire.In the recall documents, Jeep states the issue is that the pump's electrical header was built out of spec. That leads to insertion forces "which exceed the specification." Having to jam the connectors together can spread the terminals apart and that means a poor connection between the pump connector and header. Poor electrical connections can lead to higher resistance and extra heat, and that can cause a fire... hence the recall. Owners Advised To Park Outside And Away From Vehicles Jeep According to NHTSA recall documents, Jeep first learned of a potential issue in May 2023. Jeep's parent company Stellantis investigated fires in Wrangler and Gladiator models that started at the connection between May 2023 and April 2024. The investigation was closed because the fires didn't happen often enough, so "therefore did not pose an unreasonable risk to motor vehicle safety."It was reopened later that year, and the NHTSA began its own investigation in September 2024. Stellantis and the NHTSA learned of the manufacturing issue in early 2025, and continued to test and investigate.As of May 2026, Stellantis said it is aware of 63 customer assistance records and 72 field reports, with 35 of those reports confirmed to have started with the connector. It is not aware of any crashes but is aware of one injury that could be related.Jeep is "advising" owners of affected models to park outside and away from structures or other vehicles until they get their recall fix completed. That fix is dealer inspection of the connectors and replacement or repair if needed.Letters to owners will go out in July, but Jeep owners will be able to search the NHTSA's recall database starting June 11 to learn if their vehicle is affected. Jeep said that some owners could experience a loss of power steering assist or a Service Power Steering check engine alert as a warning.
