2022 JEEP GRAND CHEROKEE L Forward Collision Avoidance Problems

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.

First vehicle start of the day. Fcw off light on paddle shifters inop, all nomenclature on ipc and radio in Italian language ,all temp readings in celcius.Celsius. Happens on every vehicle key cycle.

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, 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. I am available for any needs." INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Recurring sudden loss of power steering assistance combined with simultaneous disablement of Electronic Stability Control (ESC), Automatic Emergency Braking (AEB), Active Lane Management, and Blind Spot Monitoring. Multiple separate occurrences with photographic/video evidence over the past few years, including total loss of power steering on November 9, 2025. Serious safety defect with children in the vehicle. Requesting immediate investigation. Vehicle is currently at dealership. Will provide photos of latest occurrence. Scan of vehicle system shows multiple stores codes of steering failure. More photos of previous occurrence are available upon request.

When powered up, the car's entertainment/control system switched to Italian and metric units. In addition, the Forward Collision Warning indicator lights up as disabled even though it's configured on. Unknown whether it's really on or off but if it's off, then this safety feature has become unavailable. This happened in April of this year and I had to take it to the dealership to get it reset for $250. The exact same thing has happened again--the unit has become unconfigured in Italian and metric mode and the forward collission warning disabled is again present.

On multiple occasions, vehicle screen just go blank, backup camera won’t work, do locks do not work, and forward collision detection not working for a year now after last forced over the air update for Uconnect system. Car has been to dealer multiple times and still no fix for it. Also 4wd system not working properly and vehicle pulls to side even tho alignment is set to factory specs. Also the driver seat module melted and dealer can’t figure out why and wasn’t covered under any type of warrenty

There is an issue with the sensors. While driving for no reason it will break. It’s done it multiple times. While turning left. The sensors have stopped me in front of oncoming traffic. And won’t allow me to proceed forward. There is also an issue while trying to back out of parking spots. There will be nothing behind me. But it will break and not allow me to leave. This is very concerning. I am afraid to drive my vehicle. I’ve taken it into the dealership and they weren’t able to fix it.

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.

The last forced OTA update we received on the vehicle has been a complete disaster. The build number is [XXX]. It has lit the FCW off light on the dash despite it being selected as on in the settings. It has also disabled the paddle shifters, randomly turns the language on our display to Italian, randomly locks up the UConnect system into an Android Command prompt and causes numerous issues with the radio. The update has also caused the driver's lumbar support to randomly inflate while driving the car. I've searched on many Jeep forums and this appears to be a common issue. My dealer says there is no "recall" yet from Jeep and wants to charge hundreds of dollars to reflash the software. All reports I have found online show that reflashing the software has not worked for others.

There are over a half a dozen features, including safety features that simply aren’t working: pedestrian avoidance, automatic braking, paddle shifters, high beam headlights, memory seats moving while driving, system and screens freezing or going blank while driving, Italian randomly being selected as the language, and the units of measure being switched to metric randomly among other things. I've paid the dealership $300 for a software update a year ago and now the same exact issue has happened again.

1) The 'Forward Collision Warning Off' light has continued to show on my dashboard, even though everything in the system indicates that it is on. 2) From time to time, usually when using the remote start, the system will change settings to Italian Language and also change temp to C rather than F. 3) On at least 3 occasions, when I start the car, all warning lights turn on, such as Service Power Steering, Lane Assist, Automatic emergency Braking, etc. I have to turn the car completely off, wait a few minutes, and turn back on to have thing behave as normal.

I purchased my vehicle in Sept. 2022. Issues began Nov. 2024. At first my radio screen was glitching and at the same time my car did a software update, it reset all my settings and my AEB system was disabled and would not turn back on regardless of how many times I turned it back on. The dealer did a manuel software update, replaced my screen (I paid the $100 warranty deductible) and it fixed the problem. A month and a half later it happened again without the update and my screen again was glitching. All my settings were changed and my AEB system was disabled. Dealer did a manual reset and another month and a half it happened again. At this appointment I asked them we need to do something else. This is not working. They saw that my alternate battery was not holding power well and not fully sending power to my module which controlled my radio/navigations systems also my safety features on the car. I replaced both batteries at $820. I needed 2 modules replaced. I had the module for the radio/navigation and safety features replaced and I am still currently waiting the other module that controls WiFi connections. It has been 3 weeks since I received my new module. After one week my radio screen was glitching. They said it was a lose wire and it needed to be replaced. As well as my auto start/stop button is being replaced because they most likely broke it due to them taking apart my radio so many times. Now at 3 weeks my car again reset my settings and my AEB is disabled. I have an appointment for them to look at it again but I have been to the dealer on an average once every 4-5 weeks since this issue began. Does not look like it’s going to fixed anytime soon.

Forward collision feature does not work. Does not detect possible collision and does not apply emergency braking. Dealerships told me I don’t have the forward collision warning plus unless I am using adaptive cruise control, which is false. These are two separate features.

A warning light popped up to tell me this system was disabled on my dashboard, at the same time the system switched to Italian and all of the units of measure switched to metric without warning. I took it in to the dealership and they reset everything, replaced the radio/computer, and assured me everything was working. Within a week, the same error occurred and the same issues. I took it back to the dealership and they acted like they had no idea why, but would look into it. While waiting I searched online and discovered a notice from Chrysler dated in 2024 saying this issue was occurring and dealerships should just reset the system. I also discovered a multitude of similar issues being reported by other owners of Jeep vehicles across various message boards. When I brought the "Star bulletin" to dealers attention, they admitted they were aware of the issue all along and had no idea when/if it would be fixed as it was an issue with the software in the vehicles themselves that Chrysler would need to fix. So, I was sent home with a vehicle that is not operating correctly. I have to assume the front collision and emergency braking is not working (along with quite a few other features I have discovered), and frankly I have no idea what safety features are or are not working as they could not (or would not) tell me what all was affected.

The forward collision warning turns off on it's own. Jeep did an upgrade and now the radio turns off and on by itself, changes in preference happens without warning and forward collision warning stays lit. Jeep has replaced the radio 3 times since and I've been to the dealership at least 15 times to address the issue but the issue has not been resolved. This has gone on since 2023. Jeep is aware of the issue because i read a memo addressing it at the dealership but they would not provide me a copy of it.

ABS , Traction Control, Power brake booster, AEB inoperative after routine brake pads/rotor service. Vehicle was put into service mode via touch screen radio, rear brake service performed. Upon initial brake pedal application, required to exit service mode for rear brakes, to return caliper piston contact to brake pad. The vehicle disables abs and supporting system and sets codes c0050 , c2227 . As a technician my opinion is the extra brake fluid required to take up open space after service is discharged via accumulator into the brake system with no resistance or pressure due to caliper pistons expanding to the brake pads. These faults render the power brake boost abs and multiple other safety systems inoperative until a dealer level scan tool can perform abs initialization, and a hydraulic prove out test, and clear all codes, even with all code cleared power brake boost was lack just at best on initial test drive after service. A basic routine service should not affect a vehicle as adversely as this. While dealers may know what's going on your independently run shops and DIYers may return unsafe vehicles to customers/owners. This is the 3rd vehicle I have personally experienced this with. I will up load separate reports with those vins accordingly.

The infotainment center went to error on Jeep with less than 60,000 miles. Owned from new 2 years. The infotainment center can not be accessed and it makes modifications on its own. Like choosing different language of Italian and using euro measurements. There is no way to change this. The biggest issue is that it turned off safety feature which I believe is the forward collision warning. There is no way to change safety setting with out infotainment system. It also believed to be causing battery to drain. Jeep will not assist.
