Automatic Emergency Braking Problems of Jeep Grand Cherokee - part 1

I have been having this error message appear intermittently in the car upon starting the vehicle since I purchased the vehicle in August 2024. See attached photo. The message appears seconds after starting up and will go away. Lane keep assist will turn off but I can turn it back on. Additionally, I have had a similar occurrence in multiple occasions while driving where these systems will turn off and present an orange light on the dashboard. I’m not able to turn the systems back on when this happens. It will reset itself after turning the car on and then off. I have had it in the dealer for this. The explanation was if the battery is below 80% charge this will happen. Seems like a weird response. You would think that if it happens once when the battery is allegedly under 80% charge, if you immediately turn off the car, and restart it ( not giving the car time to charge) it would happen again. I have tested that and it appears untrue. Appears to be some sort of software or sensor issues within the car. I have seen this issue online and the dealer seemed familiar with it on other cars.

Aeb system engaged emergency braking for no apparent reason when traveling at >35mph on a busy road with the flow of traffic. My face actually hit the steering wheel and a car traveling behind me barely stopped in time to avoid rear ending me. The aeb system has repeatedly displayed warning lights in the dash previously. For each occurrence, the vehicle was serviced at the dealership and reassurances were provided each time that the underlying issue was remedied with reprogramming and/or replacement of electrical control modules, however the recurrent nature of the issue (and many other issues surrounding the electrical system in my grand wagoneer) doesn't instill confidence in the "fix" they're providing. At this point in time, I don't feel safe driving my grand wagoneer, as I don't know when the vehicle will involuntarily slam on the brakes in traffic and cause an accident.

I am filing this complaint regarding my 2023 Jeep Grand Cherokee 4xe due to repeated and ongoing electrical system failures that present a serious safety hazard. Beginning in April 2025, the vehicle began displaying the warning “service hybrid electrical system. ” shortly after the warning appears, the vehicle will often shut down completely while in operation. I have taken the vehicle to an authorized Jeep dealership on multiple occasions. Each time, I was informed that Jeep is aware of the defect but that no repair is available, as a required software update has not yet been released. In June 2025, I escalated the issue directly to Jeep. During this time, I experienced an incident in which the vehicle lost all power and shut down on a highway, creating a significant risk of collision. Jeep representatives acknowledged the defect as a known safety concern but advised that there was no available fix. Because I cannot afford to park the vehicle indefinitely, I have been forced to continue driving it despite the dangers. Jeep has only provided one month’s car payment as a “goodwill” gesture, which in no way addresses the underlying safety hazard. In September 2025, after seeing a news report about a recall affecting this model, I contacted Jeep again. Initially, Jeep denied that a recall had been issued. Only after I provided them with the recall notice did they confirm that a recall was in effect. To date, no remedy or repair timeline has been provided. This issue has persisted for several months. Jeep has admitted that the defect is a safety concern, yet they have failed to provide a safe and operable vehicle. I, my children, and other motorists have been placed at extreme risk due to Jeep’s inaction. I respectfully request that NHTSA investigate Jeep’s handling of this defect, their delay in providing a remedy, and their failure to ensure that affected vehicles are safe to operate.

This issue happened 3 times in a matter of 2 months. All 3 happened in 3 different intersections. While turning left in the intersection (oncoming traffic also turning left) the vehicle jerks to a full stop in the middle of the intersection with a "crash detected" message flashing on the dashboard screen. The vehicle stayed in drive and continued to drive after full stop the first 2 incidents. On the 3rd incident, the vehicle stopped completely, and would not continue to drive. The vehicle had to be put into park (even though it said it was in drive but did not drive) and put into drive again to continue moving. Other vehicles driving behind the grand wagoneer were required to slam on brakes to prevent impact of the grand wagoneer and had to wait for the grand wagoneer to begin driving again. Unable to drive this vehicle due to safety issues. The vehicle is currently in the shop under investigation.

While driving, vehicle begins shifting down and jerking to stop. Emergency brake engages while driving.

The anti collision avoidance systems did not engage. Instead it seemed the vehicle sped up. It did not engage to stop a collision, I was at almost a stop. Vehicle seemed to speed up. Anti-collision systems did not engage at all. This system worked previously. It did not brake automatically nor avoid a collision. It caused an accident & there were minor injuries & totaling 2 vehicles mine (2014 Jeep Grand Cherokee overland) & the other party to accidents truck.

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 August 8, 2025 and obx Jeep is indicating I must again leave it with them to further diagnose the issue.

While driving my 2023 grand wagoneer the serv 4wd light and dash spelled out service four wheel drive, it lit up the anti collision light, ecs, tcs, and hold!. The parking brake also engaged automatically while driving at least 4 times. This is a serious safety concern to allow a vehicle to continue driving with the ability to automatically engage the parking brake while driving. The safety of my entire family was put at risk. I currently have the vehicle sitting at the dealership to be diagnosed and reproduced as the vehicle lost all power after this incident. Another serious safety concern is the total loss of power with no notice. This could easily have been while I was driving and caused a serious accident and possible fatalities.

Emergency electric brake system has set up a number of times on its own always when it was parked. I was towing the car behind a motorhome ,it is 2024 Grand Cherokee Jeep summit with approximately 6600 miles on it ,the electric emergency break system set up going down the road at 50 mile an hour behind the motorhome. The motorhome has 650 hp engine. I didn’t even feel the brakes set up on the car. I saw a lot of smoke behind the motorhome . I pulled over and it turned out the electric brake set and I couldn’t get it to release. I called the dealer where I bought it to see if they could tell me how to release it. They referred me to Jeep, I thought sure that they’d have someone but they referred me to a Jeep dealer in santa fe, new mexico the dealership had a tow CO haul it to the dealership and told me tow ins were 3 to 4 weeks out before they could get in and look at them . After a month and they had not looked at it I had it hauled to mike shaw Jeep where I bought it. My concern is that had I been driving that car on interstate highways in colorado 75 mph or states where it’s 85 miles an hour and the brake set up I’m going to be in the ditch or in the front of another vehicle killing my self and family or someone else family. This Jeep needs to be taken off the road before someone is killed. I refuse to drive it. Or let a family member drive it. Have had no satisfaction from Jeep dealers. I had to have a car to drive so I had to spend another $60,000 for a car. .

Was driving in a neighborhood and slowly turning at a 4 way stop, parking brake self engaged causing the car to slam to a stop and was unable to press gas. Had to put the car in park and restart (with shutoff for 30 seconds) before I could move and was stuck sitting in the middle of an intersection.

Hybrid system failure alert (red wrench)– the vehicle has shut down while driving, including on highways. When the light goes on – it has braked on its own without me touching the pedal. Dci- is the code the dealership says is coming up no fix for it.

The unit has been taken to Chrysler dealers in puerto rico three times. On each visit, we were charged $120. 00 for a total of $360. 00 for the computer scan. We were charged for an electrical module, part no. 68442478ab, worth $406. 59. The situation has not been resolved. The vehicle has abnormalities in the braking system, which consequently affects other functions and even drains the batteries. I would like to sell the unit, but it is not resalable due to the unresolved recall. I need Chrysler to offer me options such as a refund or another unit without defects.

The Jeep uconnect system control screen has delaminated form normal use which is a well documented issue on thousands of Jeeps from online research. The delamination now has the vehicle pushing buttons on the screen by itself and changing safety parameters while driving. I have a video showing that while I am driving and not pushing any buttons the screen is frantically changing steering parameters, braking parameters, collision avoidance, lane departure, blind spot, etc. I have a video of the incident and screen doing this by itself. I can not upload it due to size, but please contact me for the video and I will send it.

I purchased this vehicle 04/15/2025. Starting at less than 500 miles the blind spot indicator warning lights along with the abs braking system warning lights randomly come on while driving. To receive random warning light notices and sounds while driving is extremely startling and concerning. I have taken the vehicle to the dealership multiple times with no success of fixing the issue. They have been in touch with Chrysler’s engineers. The engineers have given instructions such as inspecting the electrical system, replacing the main module and software updates all of which have not corrected the problem. The vehicle is still at the dealership with no resolution. Apparently, these issues have been reported before not only for the Jeep grand wagoneer but other Chrysler vehicles as well. As a loyal Jeep customer, I purchased this vehicle because of the safety features advertised. However, it has become a nightmare and I do not feel safe driving in this vehicle at all. Please research these safety concerns.

Starting at around 12k miles, my odometer started flashing and backup cameras completely stopped working, unable to see while backing up, at the same time the active lane management and auto emergency braking went out as well, took my car into the dealership and was told pam module was not good and covered under manufacturer warranty, even after pam module was replaced, the active lane management and auto emergency braking is still not working.

On April 12th my husband and I were driving our Jeep after it had a recall and update to fix the recall of a battery issue on all 4xe models. We were doing 45 mph down the road and it threw an error code that said “service hybrid electric vehicle system”, “service emergency braking system” the Jeep then shut off and said for us to push the brake and press start for us to turn the car on in the middle of the road. We were able to safely get off the road, when we came to a stop the car put itself into park automatically. We had to start it a couple of times to make sure it was ok to turn around and drive home. It was then towed to the dealership. They told us they could see the issue logged in the system but they could not replicate the same issue after driving it. They told us that we had to come and pick up the Jeep and I told them how unsafe that made me feel for us and everyone on the road. They told us there’s nothing they could do for us. We got the car back and another issue arose where are passive entry switch became corroded and our car kept unlocking itself throughout the night. The day we got it back from them we were driving it and we got the same “service hybrid electric vehicle system” again. So I brought our Jeep back again and they told me in the service department they’ve been working with the engineers at Jeep and they are waiting for an update to fix it and it’s one of four in the area with this issue and Jeep is fully aware of the severity of the issue. They also told me they would be holding on to our car until it’s fixed. I was called by the head of the service department at that dealership and was told they need their loaner car back and they got word they’ll maybe have a fix for our car in November. They knowingly gave us our completely unsafe Jeep back and told us to try for lemon law - with all parties knowing the severity of the security and lives put at risk on the road. We have gotten this error code many times and are told there is no fix.

Brand new 2025 Jeep Grand Cherokee less than 3 weeks old - I just got into an accident last night on the freeway my car began to decelerate and accelerator completely stopped working. I noticed an aebs alert and engine light on the dash but came close to no other cars for this to have come on. Came to a complete stop and I look down and the car is in park. I was unable to put the car back in drive on the freeway. Put on my hazards and called 911 immediately, knowing how dire the situations was, while trying to find a way to get moving, and watched as I was rear ended by a pickup going full speed.

Traveling at around 55 mph, slowed down for a stop light. Dash started flashing and beeping and stated "shift to park then shift to desired gear. " could not accelerate, had to put in park then back in drive to keep moving. No check engine light. 2 dealerships cannot fix because there's no code. Seems to be a common occurrence on Jeep forums. Afraid this will happen again on the interstate and I will get rear ended or not be able to get off the road. Major safety concern!.

On multiple occasions now, my shifter starts blinking at me and the dash tells me to shift into park and then shift into desired gear. This is quite annoying is baffling and dangerous. Also, on multiple occasions the dash lights up it goes crazy beeping like crazy like it wants me to stop and there’s nothing in front of me for me to need to stop. This could be potentially very dangerous. I see others have had issues like this as well so I think we really need to do something about this for somebody does get hurt cause it locks up it doesn’t let you go anywhere until you put it in park and put it in gear not safe.

Aeb light comes on saying limited functionality service required. We have taken it to the dealer and they service department said no codes for that problem showed up and said if it did it again pull into any dealership and have them check it. It happens constantly so it happened right when in front of one of their dealership so we pulled in and they checked again and it did come up showing an electrical issue. They saw our pictures I was continuing to take of the dash showing how often it comes up. So I did just that and had a photo book, the size of a wedding album showing how it went off sometimes every two hours. *then the lane depart doesn't work, it will not vibrate, which we have all the settings on and set to the highest setting. Warning for cross traffic when in reverse doesn't always work sometimes it won't even go off when someone walks close to the back of vehicle. * on just a few occasion the rear door will not close when button is pushed, we have to physically close it. *sometimes it will continually slam on the breaks when we try to back out of our garage, taken several times of me putting in park and trying again. *also sometimes when backing out it won't drive when I put in drive, I have to put in park, then move it to drive. Is currently in the dealership, they have had it for 4 days and cannot figure it out but acknowledge it is happening.

Airbags failed to deploy in a front crash. Passenger side curtain air bags deployed, but none of the others deployed. The lane departure or lane keeping assistance did not work. The vehicle slowly swerved off of the highway with no safety features kicking in to help keep it on the road. No automatic emergency braking started. The vehicle was still going with the cruise control on following the collision. As of 3/20/2025 the vehicle is still available for inspection. This is the first report of this malfunction. The local sheriff was contacted following the accident. I do not have knowledge of who all has inspected the vehicle. There were no warnings or messages that the safety systems were not working. Yes, our safety was at risk. As the driver of the vehicle, I have broken my c2 vertebrae in my neck.

I have some major safety concerns with my 2022 Jeep Grand Cherokee, specifically with the aeb. Today was the second time that my automatic emergency braking came on while I’m driving down the highway at 60 mph. The first time was in November. The roads were dry, no other cars coming toward me, driving on a straight stretch, with one car a safe distance behind. My Jeep went from 60 to 0 slamming on the brakes so hard and flashing the aeb lights and dinging on the dash. Seat belts locked up tight and gave you a hard fast whip lash forward. Very terrifying like what is even happening?! the car behind me thank goodness had enough time to slam on their brakes and not rear end me! as fast as you could even comprehend what was happening, the lights and dinging stop and you can drive again. I was like maybe a leaf or something blew over the sensor and kind of wrote it off because nothing came up on my Jeep app. Fast forward to today, February 25th. Again roads are dry, no one is coming towards me, driving 60 mph in a straight stretch and wham the auto emergency brakes slam on again! hard brake from 60-0 mph. Aeb lights flashing and dinging, locking seat belts and whiplashing your head forward as you screech to an uncontrolled stop. I had absolutely no control over my brakes or gas! this time I’m livid bc my children were in the car with me! thank goodness everyone was properly wearing seatbelts and in car seats, and I had both hands on the steering wheel, and it was not on a bend in the road because this could have been very dangerous and not ended well! this is not ok and there is nothing at all that blocked a sensor or would have had any reason to cause the Jeep to engage this feature. I should not have to be afraid to drive my Jeep and now it’s literally terrifying to drive it bc you never know if it’s going to happen. It needs addressed and fixed ASAP and all Jeep owners should be made aware of this very dangerous situation!.

The vehicle came to a screeching stop with no visible reason for doing so. Three cars behind me also had to come to an abrupt and dangerous stop to avoid me. I pulled out of my driveway, began to drive, reached 10 mph, then came to a full brake, causing tires to screech. The speed of traffic behind me was approx 25mph.

A message comes through the dash screen saying def service 50 miles left vehicle not restart again , I take it to dough smith Jeep dealer in spanish fork for diagnostic they told me to replace a lot of things like def pump, def injector and nox sensor (bank 1) we do and we didn’t solve the problem after spending thousands of dollars and im not able to get my emissions ready because of that , automatic brake system failure it says to clean the sensor I cleaned really good but keep showing brake failure message.

The issues I'm experiencing are a rubbing sound when breaking and turing the wheel. The car turned on and could not be turned off. Nothing worked or responded no matter what you pushed. The brake sensor and lane assist diagnostic fault codes (error codes)popped up which they couldn't find a bulletin or error code to replicate the issue. The vehicle would not read the key fob, it would say the fob had left the vehicle because the door opened, or if I move the key while in the vehicle( bulletin for this issue). I get the call that my vehicle is ready and I'm driving away and the steering wheel vibration coming from the engine between 40 and 49mph feels like I should be driving on rumble strips, but the drive is smooth, this is coming straight from the engine or transmission when you accelerate through the steering wheel. This was not an issue before they ran their tests and fixed said problems. The computers are still updating on the screen and I hope that it evens out when the car turns on and off and the computers reset. Now today the car starts dinging and error codes are flashing on my dash. It's the lane sensor and the lane assist error code going crazy. This was the issue they couldn't replicate or find a bulletin on. Here's the fun part, the problem becomes more consistent when I apply the brakes. One time the brakes seem to not work properly. All these error codes pop up when you initiate the braking system. Then the final error code was warning me that the breaking system was faulty. I drove it straight to the dealership and left out with them again.

On January 6, 2025, one week after picking up the new vehicle from the car dealers lot I was driving on the merritt parkway when suddenly the aeb light came on and then the traction control and engine light. The vehicle quickly lost power and even with my foot pressed fully on the gas pedal, it would not accelerate and slowed to 20 mph within seconds. Fortunately, there was no car behind me, and I was able to coast into a rest stop. If there were a vehicle behind me, it probably would’ve crashed into me when my car quickly decelerated. I turned off the car and then restarted it. I was able to drive it 3 more miles and it happened again. I pulled onto the shoulder, turned the car off and restarted it a 2nd time.

This vehicle does not alert or activate forward collision warnings or automatic braking. Other reports from 2022-2023 by Grand Cherokee owners confirm that the system is not working for many Grand Cherokee.

The entire vehicle failed with a no start issue. The vehicle will not wake up, can not jump off. My safety is being stranded without a workable vehicle. No the problem has not been resolved after being towed into service to the dealer twice. The star engineers got involved this last time but asked the service center to release the vehicle to me because they could not replicate the issue. No warning lamps, messages or other symptoms to indicate a problem with the vehicle/engine/electronic system, the vehicle is just simply dead.

My Jeep, when using adaptive cruise control, will occasionally apply emergency breaking when a vehicle passes alongside me in an adjacent lane in the same direction of travel. I’ve had other cars directly behind me when this happens and it appears to other drivers like I’m “break checking” them. Usually it’s triggered when the passing adjacent vehicle is a tractor trailer or a truck pulling a trailer. Furthermore, the actual early warning forward crash detection does not work at all. I have no warning lights alerting me of a malfunction.

The contact owns a 2024 Jeep Grand Cherokee. The contact stated that while driving at various speeds, the message "automatic emergency braking (aeb) failure - service required" was displayed and the emergency brakes were erroneously activated causing the vehicle to abruptly stop. The vehicle was taken to the local dealer who reprogrammed the aeb system, but the failure persisted. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 137.

The automatic emergency braking system activates randomly while driving abruptly stopping the vehicle in traffic. This has happened several times and we no longer feel safe driving. Luckily no one has been behind us when it happens otherwise I feel a crash would be unavoidable. The vehicle has now been to the dealer twice with no repairs made. The techs are always unable to duplicate the concern. Last time this happened my wife was driving around 40mph when the crash warning message flashed and stopped the vehicle. (no one was in the way).

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 re-enable safety features, 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 four times. They provide fix that last a week, then say there is nothing they can do and to wait for a possible software update, but none has come and it has been almost 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] 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 and have all paperwork from the four Jeep visits. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Brakes lights remain on when vehicle is in park and in drive without brake pedal activation. Abs is also engaged in park and presents with hard pedal and no travel. I brought the vehicle to an authorized Jeep dealer in September 2014. Note- recall z48 software update was performed April 2023. Service notes state replaced abs module, no change. Internal pressure sensor reporting 117psi with no brake pedal input. Replaced hcu module. I paid $1529 for this repair. Fca refused to reimburse me on the original z48 recall and now refuses reimbursement for the 94b/NHTSA 24v-838 recall.

Received over the air update that continues to fail. This over the air update shut down my driver information screen and altered the driving measures and safety features. This vehicle continues to receive over the air updates that freezes my driver information and infotainment screens. This results in me having to stop an disconnect the battery to reset/ restore safe driving information. Vehicle receives phantom vehicle warning and error indications.
