The large Uconnect touchscreen is command central in your 2023 Grand Cherokee. When it freezes, you lose access to climate controls, navigation, and vehicle settings. These modern screens are essentially tablets, and like any computer, they can hang.
Types of Screen Issues
- Complete freeze - Screen locked, unresponsive to touch
- Partial freeze - Some functions work, others don't
- Slow response - Significant lag in touch response
- Black screen - Display won't turn on
- Reboot loop - Keeps restarting
Quick Fixes to Try
- Soft reset - Hold power and volume down for 10+ seconds
- Hard reset - With vehicle off, disconnect 12V battery for 5 minutes
- Wait it out - Some freezes resolve after a few minutes
- Turn off and restart vehicle - Simple power cycle
Common Causes
- Software glitch - Memory overflow or process hang
- Outdated software - Needs system update
- Corrupt data - App or setting causing crash
- Overheating - Screen too hot in sun
- Hardware failure - Screen or processor failure
Software Updates
Stellantis (Jeep's parent company) regularly releases Uconnect updates. These can be installed:

- Via USB drive from Mopar website
- At the dealership
When It's Hardware
If resets and updates don't help, and freezing is frequent, the screen or its control module may have failed. Warranty should cover this on a 2023 model.
