2024 JEEP GRAND CHEROKEE Forward Collision Avoidance Automatic Emergency Braking Problems

I had just got in and started my Jeep and noticed the ABS light and Brake light was on, so I went straight to the dealer and the abs had an internal failure and has to be replaced.

This complaint is being filed as an update to prior NHTSA complaints regarding the same vehicle and Recall 78C. The issues described below remain unresolved. My vehicle is subject to Recall 78C, which warns of a defect that may result in catastrophic engine failure due to an engine block casting issue. The recall was issued approximately 90 days ago, and the status remains listed as “remedy under development,” with no repair available and no timeline provided. Since the recall was issued, I have contacted Stellantis three separate times in writing requesting: confirmation whether the vehicle is considered safe to operate while the recall remains open, and transportation accommodation while no remedy exists. None of these emails have received a response. I also contacted two authorized Jeep dealerships seeking transportation assistance. Both initially stated they do not provide loaner vehicles and are not required to follow corporate directives. Both later stated...

I am reporting unresolved safety issues involving multiple open recalls on my Jeep vehicle, including a high-voltage battery recall and an engine recall with no available remedy. Jeep has advised owners not to recharge the vehicle and to park away from structures or other vehicles due to fire risk, yet also states that owners may continue driving the vehicle. However, the vehicle automatically regenerates battery charge during normal driving even when regenerative braking is turned off. This behavior was not explained in the recall notice and creates confusion about how to safely operate the vehicle while complying with the “do not recharge” guidance. I am also experiencing intermittent Automatic Emergency Braking (AEB) warning alerts, which raises additional safety concerns while driving under recall conditions. Another open recall related to the engine currently has no available remedy and has been unresolved for an extended period of time. Despite the safety nature...

This is a follow-up to my previous complaint. My 2024 Jeep Grand Cherokee continues to show safety-related system failures that have not been addressed by the dealership or Stellantis. The main new issue is a malfunction in the regenerative charging system. I have this feature turned OFF, yet the vehicle continues to engage regenerative charging while driving. This indicates a failure in the system’s control logic. I am also experiencing intermittent AEB system warnings. The AEB warning light activates randomly during normal driving with no obstacles present, creating uncertainty about whether the system will operate properly when needed. I reported these new issues to the dealership, but they stated they cannot schedule service until after Christmas and cannot provide a loaner vehicle. Stellantis has also not offered a solution. I am forced to continue driving a vehicle with malfunctioning safety and braking-related systems. This is an unresolved and escalating safety...

The contact owns a 2024 Jeep Grand Cherokee. The contact stated that while his wife was driving at an undisclosed speed and approaching a stopped vehicle, the Forward Collision Avoidance: Automatic Emergency Braking system failed to engage, and the driver needed to depress the brake pedal at the last minute to stop the vehicle. The contact performed a test of the automatic emergency braking system. The contact stated that while two individuals were holding a beige sheet, the contact drove towards the sheet at 70 MPH, and the Forward Collision Avoidance: Automatic Emergency Braking system failed to engage while the vehicle was near the sheet, and the vehicle struck the sheet. The contact then drove towards the sheet at 6 MPH and struck the sheet, then the Forward Collision Avoidance: Automatic Emergency Braking beeping sound engaged. The vehicle was taken to the dealer to be diagnosed, and the contact provided...

My 2024 Jeep Grand Cherokee 4xe (VIN: [XXX] ) has experienced repeated safety-related failures. With only 3,169 miles, the vehicle became inoperable shortly after purchase and remained at a Florida dealership for 9 months waiting for parts. The hybrid battery and related components were replaced. After picking up the vehicle, while driving from Florida to North Carolina on [XXX], the Check Engine light came back on. A cooling system failure was diagnosed, which caused critical safety systems to stop functioning: the forward collision warning sensor, radar, and driver-assistance features all became disabled. A technician also discovered that a component requiring nine bolts was fastened with only two, indicating improper repair or assembly and creating a serious safety hazard. I brought the vehicle to AutoStar CDJR in Hendersonville, NC, where additional issues were documented: rattling/thumping noise under the vehicle at highway speeds, wind noise entering through the front windshield, and the...

Lane keep assist and automatic emergency braking turning off on their own at startup. Issue has persisted intermittently in July 2025. Dealership has replaced parts with issue persisting. Vehicle has been in the shop over 40 days for this issue.

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...

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

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...

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.

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...

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 forward park usually works now it doesn’t and this is a 2024 jeep new from the dealer. Very unacceptable almost crash into another car bc the cluster will usually beep and show me how far I am when I get close and now i guess it just doesn’t do that anymore ? Can I get some help please and quick…..lot of money being spent on this monthly lease! I’d appreciate it thank u!!!!

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.
