What Happened
The engine control system in your Jeep Wrangler 4xe is the brain that tells your engine what to do. In some 2021-2023 models, this system might lose contact with the engine, causing it to suddenly shut down.
Risk if Unfixed
If the engine shuts down while driving, you'll lose power and may not be able to control your vehicle, increasing the risk of a crash.
Free Fix
Your Jeep dealer will update the software that controls your engine and transmission, so it will limp home safely if a shutdown happens. This update is free, and you should schedule it as soon as you get the recall notice.
