What should’ve been a routine software update has turned into a nightmare for Jeep Wrangler owners. The latest over-the-air UConnect update has caused some Wranglers to enter limp mode or fail completely, leaving drivers stranded on highways. The remote update malfunction seems to have primarily affected Wrangler 4xe plug-in hybrid models.
Jeep’s software update failure highlights the reality of software-defined vehicles, with risks that no one seems prepared to handle. While the update targeted the UConnect infotainment system, it somehow triggered powertrain failures, showing how catastrophically modern connected vehicles can fail when software goes wrong.
When Over-The-Air Updates Go WrongÂ
Several owners reported their Jeeps suddenly losing power while driving at highway speeds, with dashboard warning lights illuminating across the instrument cluster. One owner documented the whole update process on video, even showing the aftermath of his vehicle coming to a halt mid-drive with every warning light activated.
Stellantis has identified the issue as a telematics module box update and cancelled the software rollout the same day. However, the damage was already done. The company’s social engagement team advised 4xe owners who hadn’t installed the update to ignore the pop-up notification, while those who had already updated were told to avoid using hybrid or electric modes entirely. This response highlights the severity of the OTA update problems, effectively rendering expensive plug-in hybrids into compromised gasoline-only vehicles.
Instructions circulated suggesting parking vehicles in areas with good cell service, turning them on for ten minutes, and allowing the car to download a silent automatic fix. Some owners confirmed this Jeep UConnect update workaround succeeded, though Stellantis hasn’t officially verified the procedure.

The Software-Defined Vehicle Gamble
This incident isn’t isolated. Rivian pushed an update in 2023 that failed at 90% installation. Lucid owners reported updates that completely bricked their vehicles. The pattern reveals a disturbing trend where automotive manufacturers treat vehicles like smartphones, pushing inadequately tested updates that can disable tons of metal, some traveling at highway speeds.
Jeep’s Wrangler update woes prove that automotive software requires far more rigorous validation than it currently receives. When an infotainment update can disable your powertrain mid-drive, the entire premise of software-defined vehicles deserves serious reconsideration.
