2022 Jeep Grand Cherokee Driver Assist & ADAS Problems

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

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

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).almost caused crash twice!!!

After having my 22 Jeep Grand Cherokee at OBX Jeep in NC for over 10 months for electrical and camera issues it was shipped to Brown Daub Jeep in Easton, PA for overdue PA State Inspection due to the length of the repair in NC. Supposedly OBX Jeep said it was repaired but car immediately had electrical issues including FCW OFF dash light. The PA Jeep dealer corrected electrical issues following Jeep Star Publication and it was returned to me July 3, 2025. FCW OFF dash light has come back on on [XXX] and OBX Jeep is indicating I must again leave it with them to further diagnose the issue.

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.

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 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.

See attached document for complaint.

While passing through an intersection the AEB brought the vehicle to a full stop despite no forward traffic or obstructions. Warning system lights lights for other systems (traction control, airbags, etc.) lit up in the dash. A vehicle traveling behind nearly collided in light of the unwarranted braking. After coming to a complete stop the vehicle released the brake on its own and shut off the other system warning lights. Normal operation ensued.

A service was scheduled to repair the rear view camera visibility in which the dealership failed to complete. The recall repair performed did not fix the situation. The rear view camera still shows up as a blue screen as well as the parksense sensors not working at all. This is a huge safety issue as nothing is shown when backing up and no sensors work. This problem occurred randomly while starting the vehicle and has not worked since then.

While making a protected left turn at a traffic control signal, with oncoming traffic also turning left at the same time, the automatic emergency braking engaged. I was unable to override the AEB, and the vehicle came to a sudden, complete stop halfway through the turn. The vehicle behind almost impacted my vehicle due to the erroneous braking.

The contact owns a 2022 Jeep Grand Cherokee. The contact stated that the vehicle had experienced a brief intermittent display of the rearview camera image while reversing. The vehicle was taken to the dealer, where the radio software update was performed under NHTSA Campaign Number: 24V436000 (Back Over Prevention); however, the failure recurred. The vehicle was taken back to the dealer, where an unknown repair was performed; however, the failure recurred. The vehicle was taken back to the dealer, where the contact was advised that the vehicle needed to be retained for servicing. The vehicle remained at the dealer for 7 months. The dealer had replaced the two side cameras, the control module and had performed the software update with the assistance of a Jeep factory engineer; however, the failure persisted. The engineer determined that the camera wiring harness needed to be replaced; however, the part had been discontinued. The engineer determined that the wiring harness needed to be bypassed, and a patch cord needed to be installed. The dealer called the contact and informed the contact that the rearview camera was operating as intended after the installation of the cord patch. The contact declined the vehicle repair with a cord patch and inquired about buy-back assistance. The contact stated that the cord patch reduced the integrity of the vehicle. The manufacturer was notified of the failure. The failure mileage was approximately 28,000.

While driving on the highway with the adaptive cruise control set to 77mph, the forward collision alert went off and tapped the brakes while passing a vehicle towing a trailer in the lane to the right. looking back at video on my dash cam, there was nothing in the road that should have set off the warning and the other vehicle was within their lane the entire time. I have had several false warnings in the past but this was the first time it applied the brakes.

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.

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.

Had multiple close encounters with vehicles in front of us suddenly stopping and no response from system, Also front parking sensors do not indicate when approaching an object until almost in contact, might get a visual on dash cluster, then a the audible afterwards, long time in between Getting back in vehicle and starting ti leave, now sensors are both visual and beeping One more item, using the self parking feature, gad to apply brakes before feeling that our vehicle was going to hit vehicle behind us in spot

While traveling/driving with the ADAS on, the brakes slam on detecting a front end impact. The dash board disappears and the word BRAKE in all red capital lettering with a very loud beeping coming through the speakers happens. The first time it happened was in Oct of 2023 and has happened every time I travel using the ADAS. I have made an appt every time I’ve gotten back to town after traveling to have it looked at. #1 I’ve been told they can’t find a problem with it, #2 It’s been recalibrated 3 times and the service manager even asked for my permission to take my vehicle to his personal home for the weekend so that he could follow the FCA guidelines after it was recalibrated because it had to sit for a time period before it was drove. My Jeep App can show the history of its location. While traveling home the weekend of April 26, 2024 the brakes slammed on 3 times simultaneously causing all traffic behind me to lock up their brakes. Had I gotten hit I would’ve become a human pin ball across 3 lanes of Interstate 80/90. When I pulled off on the side of road so did the vehicle who almost hit me, I was so shook up I was in tears #3 I got told to not use the feature since I knew there was a problem, #4 I asked if there was something they could install to record what’s going on #5 they finally installed an “In flight recording module” the time before I drove home but upon return saying it recorded information but that they don’t know the reason why it’s doing it or how to fix it. I’ve never received a single invoice from the dealership when I’ve taken it in for this EVER!!!! I’ve only been told they have “Star cases” on it and that is enough to prove its a “buy back or lemon”, the last message I received from a Service Rep at the dealership was from Jul 25, 2024 about seeking a buy back. I sent a message today (Aug 25, 2024) asking for a plan or solution to this problem. I’ve heard nothing yet again from anyone!!!!!! I’m beyond frustrated!!!!!!!!!

The contact owns a 2022 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, the Forward Collision Avoidance system failed to alert as needed and failed to automatically stop the vehicle when another vehicle was ahead. The contact had to depress the brake pedal to stop the vehicle immediately. The vehicle was taken to the dealer; however, no error codes were retrieved. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 6,600.

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 on: Electronic Stability Control 2. Yellow warning light came on: Electronic Stability Control Off 3. Yellow warning light came on: Service Forward Collision 4. Yellow warning light came on: 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. I posted these found problems on the forum on https://www.jeepgarage.org Other Jeep Grand Cherokee Trailhawk owner also said all those problems are happening on his identical vehicle.
