What Happened
The system that powers your 2021-2023 Jeep Wrangler 4xe is a complex one, with a 2.0L engine that combines gasoline and electric power. A problem with the communication between these parts could cause the engine to shut down while you're driving.
Risk if Unfixed
If the engine shuts down unexpectedly, you'll lose power and could struggle to control your vehicle, especially on the road or uphill. This increases the risk of a crash.
Free Fix
Your dealer will update the software in the key computer systems of your Wrangler, so they'll recognize the engine shutdown as a safety feature and help you limp home safely – all at no cost to you. You should schedule the update as soon as possible, and you can contact FCA US, LLC for more information.
