Jeep Halts Faulty Wrangler 4xe Over-the-Air Update After Power-Loss Reports, Pushes Fix

Stellantis says a parked download in strong cellular coverage restores the affected telematics software.

Overview

  • Owners reported warning lights, abrupt power loss, and some vehicles becoming inoperable after the October 10 update targeting Uconnect and the telematics module.
  • Jeep disabled the problematic download and a company forum representative identified the telematics box update as the source of the issue.
  • Stellantis is deploying a corrective over-the-air rollback, instructing owners to park with strong signal for roughly 10–20 minutes before restarting to clear the fault.
  • The company says it is assisting customers whose vehicles required towing to dealerships and will reimburse related costs.
  • Stellantis has opened an investigation and has not detailed the root cause, as some owners describe near-miss safety incidents and say they are considering legal action.
