Warnings problems of the 2022 Jeep Grand Cherokee

Issue 1: after several recalls - the battery issue still remains. Often not kicking in and leaving a power deficit (loss of motive power). The gap is short, but when low speed on battery and you push the accellerator to merge/turn, etc. And there is a delay - it can cause an accident. Issue 2: the investigation of alerts of pedestrians - happens intermittently. There has never been a fix. Issue 3: the tire pressure monitoring system fails to read intermittently - a warning on the dash indicates it is not working and to get it checked. Dealership has noted problem, but never fixed. Still occurs 3+ years. Issue 4: radio/infotainment system blanks out or becomes unresponsive. When relying on this device for navigation, that becomes a problem.

Known software glich known as "the italian bug" car switches to italian and disables fcw, paddle shifting and changes many features to metric, farenheit to celsius, psi to kpa, mph to kilometers, many features can be reset but not fcw and paddle shifting. It's unknown what other features get disabled but this all causes significant driver distraction trying to reset everything while driving as they are encountered. Jeep has multiple tsbs on this with no known permanent fix.

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 forward collision warning light came on again after switching to italian. Dealership says the warranty just ran out but this multiple times this happens and clearly it has not been fixed. Fcw issue.

This happened 4 tines before 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. I am available for any needs. " information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Randomly, & without warning, the instrument cluster & uconnect display will glitch and flicker off then on but switch into language I do not speak or understand (italian). Coinciding with language switch, instrument cluster & radio display settings revert back to default settings, paddle shifter becomes inoperative (with no menu option to enable), forward collision warning (fcw) lamp turns on with no way to disable, units of measurement including speed, temperature, etc. All change & menu option to switch units back to fahrenheit gone, auto tilting mirrors in reverse off . ***this is clearly a dangerous situation because of all the functions &gauges that change while driving & the fact it is difficult if not impossible to recover from this due to the language of the setting menus, & the complexity of finding & navigating menus to try to wade through all the settings menus &change setting back, some items cannot be reset (like the fca off lamp and temp units). 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. . Read more...

Instrument panel switches to italian, forward collision off light gets stuck on and my seat moved abruptly while I was driving down the road. I have taken my Jeep into the dealership last year for this problem, it was “fixed” but has come back. Noticed the light stuck on last week. Today while I was driving the panel changed to italian and my seat moved abruptly. Many people on online forums express experiencing the same problem.

I have code b273c-00 digital crash input on my Jeep. This is the code dealerships were informed if they see this code the vehicles have to be grounded. At this time, there is no remedy for the Grand Cherokees. The dealership can't release my Jeep back due to safety reasons, and it's been with them for over an month and counting.

Without warning or being given an option to reject the update, my vehicle was updated to settings that no longer offer paddle shifting or the ability to enable or disable the pedestrian emergency braking (peb) system. The latter results in being unable to turn off the forward collision off light on the dashboard. The update also wiped out most of my settings and changed units of measure to the metric system.

Earlier this spring, when we started our 2022 Jeep Grand Cherokee, the language had changed itself to italian, the units were metric, the ‘forward collision’ off icon was stuck on the dashboard. Also the paddle shifters did not work. In may, 2025, we paid $204. 41 to gary mathews motors in clarksville, TN to ‘diagnose’ and ‘fix’ the issue. Fast forward to this month, and the issue happened again! they didn’t ‘fix’ anything. See forum where hundreds of other owners are experiencing the same exact issues: [xxx] also see star bulletin regarding this issue: [xxx] from what I can see in the forums, there is no permanent fix for this issue. Despite this, Jeep/stellantis keeps charging customers to ‘diagnose’ and ‘fix’ the issue which is a scam/fraud since they know there is no permanent fix. I have reached out to Jeep, and been promised follow-up from one of their specialists that never comes. I have all transcripts and promised timelines to expect follow up that never happen. I will attach photos where they admit they haven’t met the timeline for follow up that was communicated, and as of now, despite additional promises of communication/follow up I still have not heard from them. Having a forward collision system that does not function properly puts myself and others at risk. Also having a dash in units/language you do not understand is also a safety issue. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving the vehicle(speed does not matter as this has occurred while standing at a stop light) all safety warning lights illuminate on the dash and render all of my safety features inoperative. This includes: abs, forward collision avoidance, rear collision avoidance, and park assist. Once this happens the vehicle becomes extremely difficult to operate and to stop. The remedy is to pull over, turn the vehicle off and open the drivers side door to shut off the rac (retained accessory control), let the vehicle sit for a minute or two, then restart the vehicle. All light will remain off and the car will function normally. This issue occurs at least 2-3 times per week and is extremely frustrating. I've taken the vehicle to the dealership several times for what they have determined to be a "software issue". Several trips have been for recalls, others have been for this issue and my infotainment system going black. The infotainment system going black is the second major issue with this vehicle. The dealership was able to get the system operating again with an additional software update, however it has not completely remedied the problem. The infotainment system will still black out, but for only a quick second, then it comes back on. When it does this, I loose all settings including profiles and siriusxm programmed stations. I've done a master reset on the infotainment system and have had it back to the dealership, but it still has not been 100% resolved. This is a safety risk when it blacks out as I loose navigation, audio, and bluetooth connectivity. Now my attention is not on the road but on the failed system. Dates and timeframe for service: Dec 18, 2024. Returned Dec 19, 2024: electrical work Dec 6, 2024. Returned Dec 17, 2024: electrical work Nov 11, 2024. Returned Nov 14, 2024: electrical work sept 7, 2024. Returned sept 7, 2024: warranty recall\oil change & tire rotation July 12, 2022. Returned July 12, 2022: electrical work-software.

The vehicle in September of 2024 after a software update randomly changed the settings. The forward collision off warning light remains on (in settings the forward collision is "on", the language changed to italian, the paddle shifters stopped working, the units changed, and the grid for the backup camera was turned off). I had it serviced at Jeep. They reset the vehicle which temporarily fixed the issue, however, 3 weeks later it happened again. There is a known mopar/star case number s2108000249. This is also reported in Jeep forum. My safety is at risk due to the failure of the forward collision warning light/software malfunction. I feel that I am at risk for a forward collision. Also the paddle shifters don't work.

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.

The contact owns a 2022 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, the forward warning collision light illuminated. The vehicle was taken to the dealer, who determined that a system reset was needed following an over the air software update. The vehicle was repaired but the failure reoccurred. The manufacturer was notified of the failure but provided no assistance instead advising the the contact to take the vehicle back to the dealer. The failure mileage was 41,000.

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.

Driving down a road at 50mph during daylight hours. It was sprinkling and vehicle was in electric mode. There were no cars in front of me, or behind me at the time. While my foot was on the accelerator, there was a loss of power then collision warning engaged out of nowhere with the audible beeps, flashing on the instrument cluster, and sharp braking. The incident was brief, but certainly a safety hazard as there were no indications the automated emergency braking was going to occur.

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.

On Jan 17, 2024, at 5:39 pm, I was driving the vehicle in electric save mode, where the temperature was around -19 degree on that day and I was heading for car wash, during that time, the vehicle in front of me applied a break. I was at safe distance I applied the break as the distance was close even the anti-breaking system did not work on hitting the vehicle at that time, and then it bummed three times. I was in shock at the vehicle's behavior and lost confidence in it. So the police office impounded the vehicle. To make the road safe. None of the air bags were deployed. I am having trouble picturing what would happen if this were on the freeway.

My car just put on the emergency brakes/forward collision warning while I was driving down the road out of nowhere and slammed on the brakes.

While I was driving with my family on a highway, I deployed the drive assist function that controls the speed of the car and keeps car in lane, out of a sudden the car itself deployed a sudden quick brake without any immenant risk in fron of me ( there was no car in front of my car for at least more than half a mile) this caused a very close threat from being hit by the cars behind me amd all of my family members to be scared and worried and even my wife blamed me for slamming the brakes without any reason. I have scheduled an appointment with the dealer in the coming weeks to have it looked at and fix a recent recall as well as look into another weird noise/sounds that I was complaining to the dealer about in the past but was unable to fix or replicate.

The forward collision warning light comes on display cluster during start indicating it is turned off. Adaptive cruise control does not appear to be working because it doesn't give warning upon closing in on the vehicle in front of my vehicle and I have had to react by tapping brake to turn the cruise off. Parking collision warning works intermittently. These problems showed up after a software update done at dealership. When I took it in recently was told they could not find any problems.

Upon starting the vehicle, multiple dashboard lights came on alerting total loss of power steering system (eps). This also triggered lights related to forward collision warning, lane departure warning, and lane keeping assistance. Vehicle was nearly impossible to steer out of driveway.

Lane keeping assistance, lane departure warning, and forward collision warning-not working, it had message to service and exclamation in red.

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 7 times, 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 two years. 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. .

Power steering unavailable service required messages pops up steering becomes very tough to turn.

June 30, 2022 purchase receipt of vehicle. Did not begin using active lane management until August, approximately 800 miles on odometer. These problems came up repeatedly. 1. Yellow warning light came electronic stability control 2. Yellow warning light came electronic stability control off 3. Yellow warning light came service forward collision 4. Yellow warning light came active lane management 5. Instrument display text = active lane management (alm) unavailable service required 6. Active lane management is now intermittent 7. Instrument display text = blind spot alert off 8. When driving early morning before sunrise and going under multiple underpasses the driver instrument cluster camera came on and showed a red spot warning of obstacle under the underpass – however no obstacle was there warning lights and alarms continue to happen for the above. Fort collins Jeep service technician claims the root problem is a crushed cable part number 68510744ae located in engine compartment. Dealer has my vehicle, waiting for new cable. I don't know if this is the root cause or if other things are wrong. . Read more...

I was driving down the road doing about 35 mph and suddenly I lost power steering and car jerked to the right. Power steering light, forward collision control, lane assistance, traction control and blind spot warning lights all came on, and a message appeared on my dashboard to have them all serviced. I took my Jeep to the dealership I purchased it at in April and they are inspecting the cause of the problem. This is the second time my lane assistance and forward collision have had issues, and the dealership was unable to find the cause the first time. This is first time for power steering, blindspot and traction control.

1. In normal driving condition suddenly apply the breakes full,putting yourself at risk if you have another vehicle that comes behind you, it will definitely hit you 2. On many occasions the anti-collision system is deactivated for no apparent reason, it is almost always in specific areas, I understand that it has to do with some WI-fi signal.

While traveling on a 2 lane road with no one around the fcw system went off and emergency braked the car. No cars were anywhere to be seen. If someone had been behind me, I don't think they could have stopped.
