Automatic Emergency Braking Problems of Jeep Grand Cherokee - part 2

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.

Multiple times during the day I have a number of alerts popping up in my dashboard. These include the blind spot monitoring which continues to go on and off. Braking system, ect. Please see pictures.

I have towed this vehicle behind my motorhome for the past year and have used a brake buddy system to stop the vehicle should it ever break away from the tow brackets. I used the brake buddy system for 5 years on a 2016 Jeep Grand Cherokee prior to buying this 2023 Jeep Grand Cherokee and have never had any issues before. Recently, while towing the vehicle, I set it up for towing as Jeep recommends and either had a malfunction of the automatic electronic brakes (aeb) or the brake buddy. Even though the tires never developed a flat spot on them due to dragging the vehicle, there was pressure applied to the brake pedal that caused the brakes to get so hot that the rubber brake lines melted at the fittings or blew out of the fittings causing me to lose all fluid. The nthsa requires that all light-duty vehicles have aeb systems installed on them by 2026. I questioned Jeep as to the cause of my issue and they determined it was not their fault. I contacted brake buddy and they claimed they were just recently made aware of this problem and have since determined their system is not compatible with aeb equipped vehicles. I have talked to several installers that set up tow vehicles to be towed and they are of aware of this. Who has the responsibility to inform the public and industry that there is a problem here? Jeep advertises their vehicle is towable with all 4 wheels on the ground but makes no mention of having to install a state law required braking system in the tow vehicle or potential compatibility issues. Had this tow vehicle come loose, it could have cause damage and potentially the loss of life!.

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.

Brand new vehicle with 11 miles on the odometer. The emergency braking system does not work. If I go into the settings and make a change to emergency braking, such as far or close, the message “auto emergency braking (aeb) unavailable service required” will come up on the cluster display. Once I restart the vehicle it goes away. If I go back into the aeb settings and make a change, the message will come up on the cluster again. When I restart the vehicle and the message goes away, it still does not seem as though the auto emergency braking system is working. This is very dangerous.

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.

Since purchase, I have had problems with the u connect system, which at times renders all communication and some luxury items to be inoperable 1 week ago, car completely had both batteries drain spontaneously . Dealer replaced both batteries with no further explanation. On 5/21, on highway trip, warning lights came on, lane assist, blind spot, abs stopped working. A/c was blowing hard, but could not adjust. Windows would not open. Hatch would not open, back doors would not open , door lock/ unlock did not work. Could only use handle on inside to open car. Could not adjust side mirrors. Promptly rerouted my day trip back home via side roads and not expressway due to uncertainty of safety. Drove it right to dealer and left the car running while checking in. Car starting flashing lights while service writer was checking car in. Then all lights- headlights and tail lights went dark without touching car. Engine still running. Car is not safe or reliable to drive. Had 12,400 miles and have owned it 18 months. Mostly highway driven by retired couple. 5 th service of electrical issues since purchase. It has been kept multiple days each time.

Driving down a highway in a 70 mph zone, my car’s automatic braking system engaged causing my car to slam on brakes. There were no cars in front of me any of the times this happened. This has happened 5 times in the last two weeks. 3/5 of the times, there were cars/trucks in the right lane next to me. 2/5 of the times, there were trucks two lanes over. The first time this happened, the car behind me had to slam on their brakes to avoid hitting me. This has happened about 10 times since I have owned the car. However the incidents have happened more frequently in the last few weeks.

Today was the second time the aeb engaged while I was driving with no apparent reason. The first was in Nov 2023 while driving on the interstate at about 70 mph. The aeb engaged, slamming the car to an almost stop, alarm blared for a moment and then the car continued operating with no apparent codes or warning lights. Today it did it again while traveling about 30 mph. I was slowing down to turn into a drive. I was still headed straight with no cars around and the aeb engaged, slamming the car to a full stop, with the alarm and the dash flashing something in red. The car then drove off fine with no warning lights or indicators on the dash. I cannot reproduce the aeb reponse. In response to the first occurrence, the dealer “flashed” the software last year. I intend to take it in tomorrow for the reoccurrence. I believe it to be a safety issue not only in that my back hurts terribly from the whiplash of a stop as sudden as hitting a wall, but because had there been a car behind me on either occasion, it is almost certain they would have had to make a dramatic and dangerous swerve to avoid it or rear ended me.

April 1, 2024, I was backing out of a parking spot on the 4th floor of the parking garage at work when my car displayed an sos on the radio monitor and then my Jeep Grand Cherokee shut off and would not restart. I then had to call parking for my job to redirect traffic because I was preventing other vehicles from exiting the garage because my vehicle was unable to restart and I had to have it towed back to the dealership in waynesboro GA and pay $120 to have this done. I waited over an hour for a tow truck to come and it is still unclear why this keeps happening. I am afraid that the next time it happens I may loss my life. I also called the dealership and Jeep wave to see if there was a way to restart the Jeep but no one was able to assist with the request. The vehicle is really becoming a problem for me.

When crossing the border into mexico the aeb module falsely reports it has malfunctioned due to "Geo fence" limitations. At least that is the cause of the issue per the service department. This causes the aeb system to stay offline and inoperable which also affects the lane departure warning system as well as prevents the use of adaptive cruise control. Supposedly there will be a "software update" coming--it was supposed to happen in q4 of 2023 and now they say q1 2024 which has ended and no update. The safety of the vehicle is compromised as key safety features are offline.

Driving 35 mph on a back road, no cars coming the opposite direction, the automatic emergency braking system flashed, beeped and slammed my brakes momentarily. Luckily there was no one behind me. I attempted to pull into a parking lot and the entire electrical system went crazy, all warning lights, systems and sensors went off and I lost power steering. Had I been driving during power steering loss it would have been very dangerous. This is the second time this has occurred with the lights and power steering issue (first time for the aeb system issue) and the dealer kept the car 3 weeks to repair it but clearly the problem persists.

I have a 2023 Jeep Grand Cherokee 4wd overland, if the NHTSA would do a web search this issue is a common issue that many people are complaining and concerned about. The forward collision warning with automatic braking is not functioning or has been turned down where it is completely ineffective or is not functioning at all. I have had my vehicle in two different Jeep dealerships and have been told that the system is functioning and not showing any error codes. I have an active case working under Jeep (case # 88675524) and my vehicle was inspected by a Jeep representative on 2/20/2024, who also claims that the system is working. I have driven several different makes of vehicles with a collision avoidance system and have seen and experienced when this system functions properly, I am a police officer and currently drive a 2021 chevy tahoe with this system and have had many alerts in the two years I have driven this vehicle. I have approximately 12,500 miles on this Jeep and have not had one alert with this amount of mileage, I have has a couple close calls where I have had to take evasive action and heavy braking to avoid a collision and not even had a warning of any kind. There are to many people complaining of this same issue and many of the same people are quoting the same company verbiage and quotes from the Jeep service departments saying that the system is functioning correctly, and there is no way to test the system. Please look into this issue and research just how many people are complaining of this issue, if your going to advertise and promote a safety system on vehicles you should have an expectation that the system actually works. Any safety system that is not functioning properly puts people in danger when the said system would prevent or minimize damage in a collision situation.

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.

The contact owns a 2023 Jeep Grand Cherokee. The contact stated that while driving at various speeds, the automatic emergency braking was activated, and the vehicle came to an abrupt stop. The contact stated that the brake light remained illuminated during the failure. The contact was almost involved in a crash during the failure. The vehicle was taken to a local dealer to be diagnosed. The contact was informed that additional diagnostic tests were needed to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 14,000.

I was traveling on a road with light snow. There was a bend in the road. I lost steering and manual breaking causing the vehicle to strike a telephone pole head on. My air bags did not deploy.

I have a 2024 Jeep grand wagoneer. It has been activating it's emergency braking system randomly while driving. One time it was on a road with a 55mph speed limit the car beeped and slammed on the brakes. Morning sunny no traffic car was clean and free of dirt. Second time was on a 2 lane road speed limit 35 day light car beeped and slamed on the brakes the behind me had to go into oncoming lane to avoid hitting me. The 3rd time was after leaving the dealership after the 4th time in for service for them trying to figure out why the truck is doing this. Was on the cross street from the 2nd time. This time it high lighted a mail box in the night-vision mode and slammed on the brakes again day light no traffic car was clean. Mail box wasn't hanging in the road. We opened a case with fca for a buy back they denied it. Fca also has not issued a stop drive order. We are currently using my wife's car to transport the kids as we do not feel comfortable with the issue not being resolved with fca. My wife has the same truck hers is having the same issue but not slamming on the brakes hers is in currently with Jeep engineering and they want us to record the car when it actives the system with our phones while driving. We feel very unsafe driving the cars and is hoping NHTSA can step in with some help. At the end of the day we are both trading our less than 1 yr old trucks in for another brand and is losing around 30,000 between the 2 vehicles.

Vehicle made left turn with partially obstructed side view and struck a pedestrian in a crosswalk. Pedestrian impact with center of vehicle (license plate). No pedestrian emergency braking activated. Vehicle brought to the dealer (with le reconstruction) - front radar sensor not tracking. Further tests of vehicle with live pedestrians walking in front of vehicle; both from step off curb into bike lane and live pedestrians walking across the front of the vehicle with no alert or apparent tracking. All tests performed above 3mph (5kph) and below 39mph. Test also above 30mph with lane line activation, but did not detect pedestrian path intrusion. Inside, the aeb for pedestrian emergency braking is on, with "warning + active braking". See photos. Tested with all three sensitivity settings (med, near, far). Additional: rear sensors worked while in reverse with a pedestrian side approach. Bosch cdr/edr 900 connected, no pedestrian option illuminated (only airbag). Further: tested another Grand Cherokee with similar trim options, on similar tests and it too did not detect or alert to pedestrian path intrusion.

- my spare tire, lane assist, and/or emergency breaking, which none went into effect during the incident. - I was forced off the road where I collided with a parked car on the side of the street, which led me to being taken by ambulance to the local hospital. - not yet, my vehicle is currently at a body shop being repaired. - I asked my insurance to investigate when they went for the appraisal, but am unsure if it was done. - no warnings were given prior to the collision.

My emergency braking system doesn’t work and Jeep corporate can’t fix it. The car won’t stop and won’t notify me in an emergency and it’s not safe. The dealer gave me a second Jeep and it has the identical problem. That VIN is 1c4rjkag9p8898184. The dealer also said they have no fix for this issue. Please contact me 914-830-2598 john giannico.

I was turning at an intersection when I got rear-ended. I do not recall the car stopping right before I got hit, but there is video that shows the my Jeep stopped suddenly during the intersection right before I was rear-ended. It appears the oncoming car turning the opposite way got too close causing my automatic braking system to immediately stop my car while I was driving. There is no other explanation as to why the Jeep just suddenly stopped as I know I did not press on the brakes myself.

The contact owns a 2023 Jeep Grand Cherokee. The contact stated while driving 15 mph, the messages indicating that 4-wheel drive mode was disabled, and that the emergency brakes were applied, were displayed. The vehicle suddenly turned off. The contact stated that there were no vehicles in front of the vehicle at the time the failure occurred. The contact was able to veer to the side of the road. The contact stated that upon starting the vehicle, the messages were no longer displayed. The contact continued driving; however, the vehicle failed to shift smoothly into the intended gear. The vehicle was taken to the dealer, where diagnostic codes related to the transmission valve body were read. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 1,100.

While turning left, vehicle hit brakes on its own, driver and two passengers experienced neck pain. Two vehicles behind both screeched to a halt. There is dash cam video, but won’t let me upload.

Airbag requiring service light came on at 100 miles. Then the sos call button was stuck lit up with an error message on the touch screen every time vehicle was started. Then the aeb system went off while driving (not in danger of being in a crash) and brought the vehicle to a stop and put itself in park and shut off. Vehicle would not start again after that. Had to get it towed.

Vehicle sets automatic brake when backing up. The back up camera turns red as if something was blocking when nothing is there. When attempting to go in reverse the car kept stoping on its own and putting the emergency break on. It took multiple attempts to get out of the parking lot and has happened more than once.

Crossing 4 way intersection with no cars or animals in site and while accelerating at about 40 mph vehicle came to a shuddering halt in the middle of the road for no reason. My husband and I were both thrown forward whipping our necks back and forth and my collar bone taking a direct hit with the seat belt. There were no sounds to warn us, no lights came on it just slammed its own brakes for no reason. My dealership brought me a loaner and vehicle was towed to them where they are working on getting the issue solved, but I am going to be terrified this will happen again and rightly so.

Numerous messages regarding safety features appearing on cluster advising service required: active lane management, blind spot alert, auto emergency braking, rear braking assist features vital to safe operation of vehicle, stellantis / fca has zero knowledge & info as to cause of failure & fix.

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.

Twice in the last month I was driving to work on a two lane road without any objects in the roadway and the forward collision warning system automatically applied the breaks hard enough for my coffee to splash out of my coffee cup. It occurred at almost the same spot on the road. However, I drive this road at least twice a day. I'm concerned that it might apply the breaks randomly while driving on the highway, thus causing an accident. I have reported it to the dealer. Despite me relaying my safety concern to them, I am unable to get an appointment until July 8th.
