2022 Jeep Grand Cherokee: false forward collision warnings

Filed Aug 1, 2026 · Driver assistance, Electrical · IN

My vehicle has multiple software and electrical issues that Jeep has been unable to diagnose or repair, and there is currently no recall addressing these problems. One of the most serious issues is that the vehicle will randomly switch the display language from English to Italian while I am driving. When this happens, the speedometer changes from miles per hour (MPH) to kilometers per hour (KPH), making it difficult to know my speed without pulling over and manually changing the language back to English. This creates an unnecessary safety concern. Additionally, the automatic door lock feature no longer functions properly. Although the dealership has repaired it in the past, the problem has returned. I also continue to receive a dashboard warning indicating that the Forward Collision Warning system is disabled, even though the feature is clearly enabled in the vehicle's settings. This inconsistency raises concerns about whether the safety system is functioning as intended. Another ongoing issue is that the vehicle randomly drains its battery. Both AutoZone and the dealership have tested the main battery and the auxiliary battery, and both have been found to be in normal working condition. Despite this, the battery drain continues to occur without explanation randomly. These recurring software and electrical problems have become unacceptable. Jeep has been unable to provide a permanent solution, and I believe the company should stand behind its product by acknowledging and resolving these issues.

The Forward Collision Warning (FCW) and Automatic Emergency Braking (AEB) systems on my 2022 Jeep Grand Cherokee are consistently failing to operate as intended, creating a significant safety hazard Symptoms include: System Inactivity: The FCW fails to alert or provide braking assistance during clear, high-risk frontal collision scenarios. Persistent Warning Lights: The 'FCW OFF' indicator illuminates on the instrument cluster and cannot be cleared by toggling settings in the Uconnect 5 system. Software Defaults: Following Over-the-Air (OTA) updates, the FCW and Pedestrian Emergency Braking (PEB) systems default to 'OFF' and often remain disabled despite user attempts to re-engage them. Hardware Misalignment/Blinding: Frequent 'ACC/FCW Limited Functionality' messages occur even in clear weather with clean sensors, indicating a potential calibration or module communication failure. I am referencing XXX and Manufacturer Communication XXX regarding these specific software/hardware faults. Despite these known issues, the dealership Ziegler Chrisler Doodge Jeep Ram in Schaumburg, IL has been unable to provide a permanent resolution. This failure leaves the vehicle without critical, advertised safety protections during operation

I own a 2022 Jeep Grand Cherokee that is experiencing unintended automatic braking while driving. The crash detection/forward collision warning system shows a constant warning light on the dashboard. While driving under normal conditions with no obstacles present, the vehicle will suddenly brake on its own. This has occurred multiple times and now happens almost daily. The problem first occurred on November 26, 2024, the same day I purchased the vehicle used with approximately 34,158 miles. The issue has continued as the mileage has increased to approximately 51,500 miles. This creates a serious safety risk because the vehicle can suddenly brake in the middle of traffic without warning, which could cause another vehicle to collide with the rear of my vehicle. I am concerned about the risk of a crash or injury. The problem has been reported to the dealership multiple times since purchase. The vehicle has been in the shop for repair attempts, but the issue has not been permanently corrected. The warning light remains on and the unintended braking continues to occur during normal driving. The vehicle is currently available for inspection.

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. 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). I have had this to the dealership 4 times to be fixed without success. Because this is dangerous (for settings/gauges/units to no longer be useful while driving), and it occurs randomly.

Issue has occurred at least 4 times: upon start, vehicle infotainment system appears in Italian language (difficult to revert to English as menu controls are now in a foreign language). Forward Collision OFF warning light illuminates on dash. Vehicle settings show all forward collision warning systems are ON. Servicing dealership has not identified any Diagnostic Trouble Codes with forward collision warning systems. Only way to reset system is dealer service via propriety manufacturer software.

Screens switches to Italian, also screens freeze or go blank, Front Collision Warning (FCW) light illuminates and can't be turned off. Bluetooth randomly disconnects, Auto door locks don't engage; paddle shifters for manual gear selection cease functioning, pedestrian avoidance, automatic emergency braking, and high-beam assist stop working; memory seats unexpectedly adjust while driving. I have to bring the car to the dealer to fix this, this happens every 14 days or so.

The system has many errors, The primary issue is the forward collision warning indicator light is on showing that the service is off. But it isn't, you can go into the system settings and turn the service on and off without issue. The light stays on. It does work as far as I can tell also. It seems to be causing the paddle shifting to be disabled. I can't downshift going down a steep grade and am being required to use by brakes. Which can be very dangerous. It is causing another issue that I cannot recall at the moment. There is another issue with the settings of the vehicle randomly changing to Euro type metric settings. The clock changing to 24 hour, tire pressure changing to kpa? mph changing to kph, all the different unit of measurements changing over. Randomly, not at the same time but consistently every few weeks. At first it seemed like it was connected to a monthly software update, but now its random. The vehicle has been taken to a Jeep dealership in Sherman, tx about the issue of the Forward collision system and they fixed it. Then the problem reappeared a month afterward. I've called and they confirm that the correct US software is installed. I am the only driver of the vehicle, so no one else is changing the settings. I work a full time 9-5 job and do not work close to a dealership, which has become an issue for these matters. All the issues I have had with the vehicle seem to be related to them updating the software without my approval. Currently my vehicle has 71k miles on it and won't be covered by the 50k warranty. The warning light issue started after 50k miles.

I have taken it to the dealer for diagnostic, they found no error codes but found service bulletin S210800193 and S2108000221 performed IPC Customer programmable features Configuration to temporarily correct the issue, but it happened again 3 weeks later. I had to pay $254 for this service, and the issue isn't fixed. Here is an example forum discussion, indicating many if not all vehicles are affected: https://www.jeepgarage.org/threads/forward-collision-warning-off-light-is-stuck-on.250301/#replies 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 https://dot.report/bulletins/11006236 Because this is dangerous and very distracting while driving (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.
