Is there a fix? Manufacturer service bulletins

The failure pattern owners describe
These fifteen 2023 Grand Cherokee L owners describe an electrical system in serious disrepair. The infotainment display blacks out, pixelates, or restarts without warning while driving—disabling the rearview camera, locking out navigation mid-trip, and sometimes forcing the transmission into manual mode. Five owners report the display resetting to Italian on every startup, with no available software fix.
Starting and key recognition is unreliable: one owner could not start the vehicle without the fob touching the ignition; another experienced complete battery drain despite a new battery installed at purchase, accompanied by chirping sounds before shutdown. The dealership diagnosed a door switch rather than the electrical drain.
Door locks fail catastrophically. One child was locked inside a running vehicle with inoperative remote entry—fire department had to break the window. Another owner reports four doors locking independently while a passenger was exiting.
Safety systems malfunction: owners describe sudden, violent automatic braking with no collision present; unintended acceleration with non-responsive brakes (resulting in a parking lot collision); and spurious warning lights for collision detection and lane management that cannot be disabled.
One owner reports the vehicle caught fire in the engine compartment on startup, with the problem recurring after a dealership attempted repair with a sensor replacement.
Across these narratives, dealerships consistently claim they cannot reproduce failures or find diagnostic codes. Jeep issued a technical service bulletin but no recalls.

Since I bought the vehicle in February 2025 I have reported the infotainment screen failure/ going black while driving.

Bought vehicle and reviewing safety features the next day I realized the Forward Collision Warning light was on because it was malfunctioning and not just turned off. Same with the AEB light.
