The failure pattern owners describe
Thirteen complaints describe a cluster of interconnected electrical problems. The most common issue: random, unannounced cluster language switches to Italian paired with factory resets of all settings, metric unit conversion, and function lockouts—paddle shifters and auto door locks stop working with no menu to restore them. Owners also report stuck forward collision warning lamps that remain illuminated even after sensor testing confirms the sensors themselves work fine; this disables the actual braking and warning function. Several complaints reference a STAR bulletin (MOPAR case S2108000249) and mention Stellantis over-the-air software updates as the trigger.
More serious: one owner describes an IPC module that failed repeatedly, causing the vehicle to shift into park while driving, lose power steering, and surge RPMs without throttle input. Another vehicle's entire dash cluster went blank while driving. A third experienced radio-induced battery drain severe enough to stall it at a traffic light with children on board. One push start button fell off into the engine bay with zero warning. Several owners paid $300+ diagnostic fees for dealer resets that worked temporarily, then the failures recurred. Dealerships acknowledge these as "known issues" but offer no fix; Stellantis tells owners to wait for software updates that haven't materialized over a year or more.

Failure modes owners describe
Instrument cluster language switch to Italian with cascading system resets
Instrument cluster, gauges, and displays randomly switch to Italian language. Coinciding changes include reversion of cluster and radio settings to factory defaults, units of measurement switch to metric, and numerous other settings reset unpredictably. Owners report this occurs randomly without warning and can happen multiple times over vehicle ownership. Language barrier prevents easy troubleshooting of menu settings.
When: Random occurrence; narratives indicate issues began after over-the-air software update approximately 1-2 years prior to complaints
Symptoms owners cite: Instrument cluster language changes to Italian; Units of measurement change to metric (speed, temperature); Cluster and radio display settings revert to factory defaults; Multiple vehicle settings reset unpredictably
Repairs/costs cited: Some dealers perform software reset for $300 diagnostic fee; issue recurs randomly. No permanent fix available. Owners report dealer says to wait for software update that has not materialized after 1+ year
Recalls/TSBs owners mention: Stellantis/Jeep dealers advise waiting for software update; some dealers charge $300 for temporary software reset. No recall issued. STAR bulletin referenced by owners but not formally named in narratives
Forward Collision Warning (FCW) off lamp stuck illuminated after software update
FCW off lamp turns on randomly, particularly following over-the-air software updates, and cannot be disabled through menu settings. Owners report the lamp remains illuminated even after attempting to reset all settings, and in some cases sensor recalibration testing shows sensors are functional but lamp persists. This disables the forward collision warning safety feature (sound and braking function).
When: Occurs randomly following over-the-air software updates; one narrative dated May 2025 and recurrence May 2, 2026
Symptoms owners cite: Forward Collision Warning off lamp illuminated on dash cluster; Cannot be disabled through vehicle menus; Forward collision warning safety feature (sound and braking) becomes inoperative; Persists even after sensor recalibration testing confirms sensors functional
Repairs/costs cited: Dealer software reset attempted; owners report lamp cannot be reset via menus. Sensor recalibration testing performed but does not resolve illuminated lamp
Recalls/TSBs owners mention: Dealers note STAR bulletin on invoice (case S2108000249 referenced in one narrative). MOPAR aware of issue per owner forums and STAR publication. No recall or warranty coverage offered
Paddle shifter inoperative with no menu to re-enable
Paddle shifters become inoperative when the instrument cluster language switches to Italian or following software updates. Owners report no menu option appears to re-enable the paddle shifters, even after attempting to reset all other settings manually.
When: Occurs during random Italian language switch events and after software updates
Symptoms owners cite: Paddle shifters become inoperative; No menu option available to re-enable paddle shifters
Repairs/costs cited: Owners unable to reset paddle shifter function through available menus
Pedestrian Emergency Braking (PEB) lamp illuminates without user control
Pedestrian Emergency Braking lamp turns on randomly and cannot be disabled through menu settings during cluster language switch events.
When: Random occurrence coinciding with Italian language switch events
Symptoms owners cite: Pedestrian Emergency Braking lamp illuminates; Cannot be disabled through vehicle menus
IPC (Instrument Panel Cluster) module failure with vehicle putting itself into park while driving
IPC module fails and remains faulty, causing vehicle to shift into park while driving multiple times during vehicle ownership. Additional symptoms include power steering loss, engine not shutting off after shift to park, blank dash display, RPM surging, and vehicle accelerating without throttle input. Owner reports dealership knew of issue but concealed service history and did not acknowledge failures on multiple service visits.
When: Over 2+ years of vehicle ownership; multiple occurrences
Symptoms owners cite: Vehicle shifts into park while driving; Power steering loss; Engine does not shut off after shift to park; Dash display goes out or blank; RPMs shoot up unexpectedly; Vehicle accelerates without throttle input; Multiple modules not updated or faulty
Repairs/costs cited: Second dealership found IPC module keeps failing, most vehicle modules not updated, and some modules faulty. Still working with Stellantis to troubleshoot; vehicle cannot be returned to owner while IPC module faulty due to safety hazard. Original dealership (Matt Bowers Jeep, Baton Rouge) returned vehicle multiple times without repair or acknowledgment of issues
Recalls/TSBs owners mention: Stellantis involved in troubleshooting but no resolution provided. MOPAR made aware but has not returned messages per owner
Instrument cluster display goes blank while driving
Dash cluster display becomes completely blank, eliminating ability to see speed and other critical safety information from instrument cluster.
When: Occurs during normal driving
Symptoms owners cite: Instrument cluster display completely blank; Speed and other gauge information not visible
Recalls/TSBs owners mention: Similar issue addressed in recall for 2021 Jeep Wrangler and Gladiator per owner research
Battery drain caused by radio/electrical system
Vehicle experiences repeated battery drain leading to dead battery. Dealership identified radio as cause of battery drain affecting both vehicle batteries. Owner jumped vehicle to reset diagnostic code but vehicle died at traffic light with three children in vehicle, requiring police assistance and towing.
When: Multiple occurrences; incident occurred during stop at red light
Symptoms owners cite: Battery dies unexpectedly; Battery drain traced to radio causing dual battery depletion; Vehicle stalls unexpectedly while driving
Repairs/costs cited: Dealership identified radio as cause of battery drain; repair not detailed in narrative
Push start button falls off into engine bay
Push start button becomes loose and falls off into engine bay with no warning signs or dealer notification during routine maintenance. Owner notes this creates emergency safety risk as there would be no way to turn vehicle on or off in emergency situation.
When: Occurred during normal vehicle operation; owner discovered button missing when attempting to start vehicle
Symptoms owners cite: Push start button falls off; No warning signs of wear or looseness
Auto door locks inoperative during cluster language switch events
Auto door lock function becomes inoperative when instrument cluster switches to Italian language. No menu option available to re-enable the function.
When: Occurs during random Italian language switch events
Symptoms owners cite: Auto door locks become inoperative; No menu option to re-enable auto door locks
Screens glitch during driving with inconsistent vehicle operation
Vehicle screens glitch while driving. Auto stop-start system fails to function. Rear hatch will not close sporadically. Multiple dealerships acknowledge these are 'known issues.' Electrical system issues cause vehicle to drive inconsistently. Batteries have been replaced without resolving issues.
When: Multiple occurrences; ongoing electrical issues
Symptoms owners cite: Screen glitching while driving; Auto stop-start system malfunction; Rear hatch fails to close sporadically; Vehicle drives inconsistently; Persistent after battery replacement
Repairs/costs cited: Battery replaced; issues persist. Dealership acknowledges these are 'known issues' but does not provide permanent fix
Recalls/TSBs owners mention: Dealership acknowledges 'known issues'
