2022 JEEP GRAND CHEROKEE L Electrical System Problems

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.

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...

On Friday, January 16, 2026, I was involved in a head-on collision. During the accident, the airbags did not deploy, and the seatbelt failed to lock, which resulted in me not being properly restrained. As a result, I suffered a mild concussion along with significant bruising. In addition to this serious safety concern, we have made numerous complaints regarding ongoing electrical issues with the vehicle. These include the screens frequently changing languages and measurement units, blacking out entirely, or becoming unresponsive. The paddle shifters have also never functioned properly, despite the vehicle being serviced multiple times for this issue. What is especially concerning is that these same problems are widely reported by other Jeep owners online, yet they continue to go uninvestigated and unresolved. Given the safety implications, these issues warrant immediate attention.

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....

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.

What component or system failed or malfunctioned? Electrical system: infotainment display module, BCM, passive entry antenna, ignition/start system, and electronic power steering. Vehicle available for inspection. How was safety put at risk? The vehicle locked my children inside and would not start, requiring assistance to open it. The power steering failed for several hours, leaving the car unsafe to drive. Ongoing electrical instability creates unpredictable loss of critical functions. Has the problem been reproduced or confirmed by a dealer? Some issues were confirmed by the dealer (screen blanking, key fob failure, antenna fault, software issues). Others, including the power steering failure and lock-in incident, were not reproduced but were documented and acknowledged. Has the vehicle or component been inspected? Yes. The Jeep dealership has inspected the vehicle multiple times, performed software updates, antenna replacement, PCM updates, and a steering update. They provided history and advised contacting Jeep Cares. Warning lamps,...

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

Passenger lumbar support bladder bags blow up in their own causing seat leather to stretch and seat back to pop off. Took to dealership, the whole fuse and/or electrical panel related to passenger seat controls is faulty. This is the second time this has happened to my jeep.

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...

June 2, 2023 power steering went out while driving, lights on dash came on, mileage on vehicle 15,869. Was out of town, stopped vehicle for about an hour, lights on dash no longer visible, power steering returned. Vehicle brought into dealership on June 22, 2023, EPS was updated. March 17, 2025 same thing happened, mileage 31,966. This time it happened when vehicle was turned on. Turned vehicle off several times, power steering returned, but engine light remained on for a day. March 19, 2023 brought vehicle into dealership and codes were cleared according to work order. It is next to impossible to turn or control vehicle when this happens. The wiper hose has disconnected twice since purchase of vehicle and has been reconnected at dealership both times.

Battery is being completely depleted by unknown source. Vehicle will not start or any functions do not work. A one day old new battery was completely drained and depleted in a 24 hour period.

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.
