2022 Jeep Grand Cherokee L: false forward collision warnings

Filed Aug 5, 2026 · Driver assistance, Electrical · IA

Forward Collision Warning has been disabled since a forced OTA software update in August of 2024. Jeep has issued a STAR report to their dealers (S248A000013). Jeep acknowledges it is an issue, but fails to cover the remedy. Dealer wants $200+ to diagnose plus the cost of the software refresh. The system forces you to take the software update, removes a key safety feature, and then Jeep wants you to pay to restore it. This is a major issue with this model covered in the forums and should be addressed via recall. [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The initial safety issue began with the rear-view camera going blank and the Uconnect 5 screen freezing while the vehicle was operating in reverse. My vehicle's service record indicates that Safety Recall 24V‑436 / FCA Campaign 79B was marked as "Completed" in the FCA system on June 19, 2024—even though the official recall was not initiated until around June 25, 2024, and no physical software update was performed at that time. To resolve the recall, I took my 2022 Jeep Grand Cherokee L to Performance Chrysler Dodge Jeep Ram in Delaware, Ohio, where technicians updated the software to version FCA-MY24.U33.43-PROD. Immediately following this dealer update, several core vehicle and safety functions failed: Forward Collision Warning (FCW): The FCW system automatically turned off, and the option to re-enable it completely disappeared from the vehicle settings menu. Vehicle Safety & Operational Controls: Automatic speed-sensitive door locking and paddle shifter functionality were completely disabled. I returned the vehicle to the dealer, where technicians reflashed the software to restore the user configuration options and re-enable FCW. However, the Uconnect system remains dangerously buggy: Active Safety Alerts: The amber FCW OFF light illuminates continuously and gets stuck on. While ADAS features appear partially operational, the constant amber warning obscures real-time system failure notifications. Backup Camera & System Latency: The Uconnect system routinely freezes, introducing a dangerous delay in the rear-view camera feed during reversing maneuvers. System Instability: The Uconnect software randomly resets to the Italian language, resets rear-camera display settings, disables automatic door locking, disables paddle shifters, and causes seat auto-adjustment malfunctions. Stellantis has since issued TSB 08-221-26 (Software Version U41.10), which explicitly acknowledges that these exact software bugs—including the persistent FCW OFF light, screen freezes,

Randomly, and without warning, the instruments, gauges, and displays will switch into a language I do not speak or understand (Italian). Coinciding with the switch to Italian language, cluster and radio display settings revert back to default settings, auto door locks and paddle shifter becomes inoperative (with no menu to enable), pedestrian emergency brake (peb) lamp or forward collision warning (fcw) lamp turns on with no way to disable, units of measurement including speed, temperature, etc. all change, and many other random settings change as well. ***This is clearly a dangerous situation because of all the functions and gauges that change, and the fact it is difficult if not impossible to recover from this due to the language of the setting menus, and the complexity of discovering and navigating through all these changes. I have taken it to the dealer twice, and they say there is nothing they can do and to wait for a possible software update, but none has come and it has been over a year. When this happens, even if one is able to wade through all the settings menus and change setting back, some items cannot be reset (like the FCA off lamp). According to various Jeep owner forums, some dealers have been able to reset something and temporarily correct the issue, but they charge for this service, and the issue returns randomly again. Here is an example forum discussion, indicating many if not all vehicles are affected: [XXX] Many people on the forum believe this issue did not start until a software update a year or so ago. This is a well known and widespread problem, and there is even a DOT Bulletin on the issue: dot.report Bulletins Because this is dangerous (for settings/gauges/units to no longer be useful while driving), and it occurs randomly, I strongly believe this issue should be a manufacturer recall.

My 2022 Jeep Grand Cherokee L experienced a sudden, simultaneous failure of multiple electrical, safety, and driver-assistance systems. Without warning, the instrument cluster illuminated a yellow warning light indicating that the Forward Collision Warning (FCW) system was disabled and unavailable. Concurrently, the steering wheel paddle shifters completely stopped functioning, and the vehicle randomly reset its primary language setting to Italian reverted its system units to Metric and Celsius. Furthermore, critical user customization options in the Uconnect 5 infotainment system—specifically the auto-folding side mirrors option, automatic door locking preferences, and passenger seat controls—completely disappeared from the settings menus.

There is a continual problem with this car. Randomly, about every 1-2 weeks, my entire infotainment center, customer settings, and seat preferences will reset to Italian and the metric system. When this happens, the front collision warning system turns off. The radio screen also begins to flash on and off, where I cannot use the backup camera and audio cuts out. I have had it to my local Jeep dealership about 6 times now, and they are able to reset the system but the problem comes back. I had it there earlier in the week and the technician told me that there is no permanent fix, and that I will be coming back routinely because I am not the only one with this issue.

Forward collision warning system not working. Light on dashboard says system disabled. Paddle shifters also disabled. Temperature readings in metrics and language keeps changing. This is available for inspection if needed. We bought this car because of the collision warning and braking system safety features and none of them work. This puts our safety at risk. The dealer has updated the system but unfortunately it was only a temporary fix. The jeep dealer confirmed the issue and states there is no permanent fix for the issues. It first appeared in July and has been ongoing.

In November 2024, Jeep applied an over-the-air software update to my Jeep Grand Cherokee L without my request. Immediately after the update, the forward collision warning system malfunctioned and warning indicators appeared. At the same time, multiple electronic body control and safety-related functions changed or stopped working, including the automatic door locks and several vehicle settings resetting (language, units, and driver-assist preferences). The affected systems are electronic safety and body control components and are available for inspection. The malfunction of the forward collision warning system puts vehicle occupants and others at risk because the vehicle may fail to provide collision alerts intended to help prevent or reduce the severity of a crash. There was no crash, damage, or hardware failure before or after the update. The vehicle operated normally prior to the software update. These problems have continued without interruption for more than 13 months and have not corrected themselves. The issue has not been confirmed by a dealer because Jeep Customer Care has required a paid dealership diagnosis before escalating or correcting a problem caused by its own software update. The vehicle has not been inspected by the manufacturer or any third party. Warning lights and messages related to the forward collision warning system first appeared immediately following the November 2024 update. Jeep/Stellantis has acknowledged similar over-the-air software-related issues in internal technical documentation (STAR Publication Case Number S2108000249, Revision C). This is a safety-related software defect affecting forward collision warning and driver-assist systems.
