2024 Jeep Grand Cherokee: false forward collision warnings

Filed Jun 14, 2026 · Driver assistance · CO · crash

On XXX, at approximately 8:45 AM in [XXX], my wife was driving our 2025 Jeep Grand Cherokee 4xe. She was stopped at a red traffic light and, when the light turned green, proceeded to make a normal left turn through the intersection. While approximately halfway through the intersection, the vehicle unexpectedly displayed a forward collision warning ("BRAKE!") and aggressively applied the Automatic Emergency Braking system. The weather was clear and sunny, and there was no apparent vehicle, pedestrian, obstacle, or other hazard in the Jeep's path that would have justified an emergency braking intervention. The unexpected braking caused the Jeep to decelerate abruptly in the middle of the intersection. As a result, a truck traveling behind the Jeep, at an estimated speed of approximately 10 mph, rear-ended the vehicle. A second vehicle then rear-ended the truck, resulting in a multi-vehicle collision. A police report was filed, and my wife was determined not to be at fault for the accident. We are submitting this report because we are concerned that the unexpected activation of the Automatic Emergency Braking system may represent a serious safety issue that could endanger vehicle occupants and other motorists and should be investigated.

On 5/11/26 at approximately 7:40pm, I was driving a leased 2024 Jeep Grand Cherokee in [XXX] , turning left at the busy intersection of [XXX] and [XXX] . I was in the outside lane of a double left-turn lane with a green left-turn arrow, while opposing traffic was also moving through the intersection in its own turn movement. In the center of the intersection, the vehicle suddenly activated Forward Collision Warning and then Auto Emergency Braking without warning, even though I was lawfully proceeding through the turn. The vehicle stopped abruptly and forcefully in the middle of the intersection, leaving my car stranded in active traffic. I braced for a rear-end collision, which surprisingly did not occur as there must not have been another car behind me After the sudden stop, I was unable to shift the vehicle back into Drive for several seconds. By the time I was able to move the car again, the light had turned red and other lanes of traffic were beginning to proceed. This created an immediate risk of a serious collision from cross traffic or vehicles approaching from behind. The force of the unexpected stop was strong enough to cause neck pain. By chance, no other vehicle struck my car, but this was a near-miss event with clear potential for severe injury or death. I no longer feel safe driving this vehicle. In addition, this vehicle has had multiple recalls and other issues, which heightens my concern that this may be part of a broader safety defect involving the Forward Collision Warning, Auto Emergency Braking, or related electronic control systems. I am requesting that the federal safety agency investigate whether the 2024 Jeep Grand Cherokee can falsely detect a collision risk during a lawful left turn and improperly engage automatic braking or otherwise prevent the driver from promptly returning the vehicle to Drive. Relevant documentation can be provided, including VIN, mileage, service records, recall history, and any dealer inspection results INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.

The Active Lane Management (ALM) and Auto Emergency Braking (AEB) systems on this 2024 Jeep Grand Cherokee 4xe fail repeatedly while the vehicle is in motion at highway speeds. The defect began at 384 miles. The ALM system will silently disable itself, and the AEB system forces the vehicle to display an 'AEB Limited Functionality Service Required' warning. Following six distinct repair attempts, the authorized servicing dealer (Eide Chrysler) stated in writing via text message on March 5, 2026, that this is a 'known issue' and that FCA engineering currently has 'no fix' available. The manufacturer has attempted to dismiss the ongoing hardware failure as a resolved hybrid battery software recall, but the collision avoidance systems remain actively defective. Because the steering overcorrection and sudden loss of emergency braking present an immediate crash risk, the vehicle is unsafe to operate.

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 the recording of the Forward Collision Avoidance: Automatic Emergency Braking system failure to engage as needed; however, the contact was informed that no failure was found. The Service Director at the dealer informed the contact that the engineers for the manufacturer stated that the vehicle was functioning as designed. The manufacturer called the contact and offered monetary compensation to keep the vehicle; however, the contact declined the compensation and requested a trade or buy back assistance. The vehicle was not diagnosed or repaired. The dealer offered to trade the vehicle for a 2025 Jeep Grand Cherokee. The contact test drove the vehicle with a staff member from the dealer inside the vehicle, and the vehicle experienced the same failure. The failure mileage was approximately 200.

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 Check Engine light still on. The advisor noted in writing that the vehicle had been in the Florida dealership for nine months and now shows new faults. As of December 7, 2025, the vehicle is again in the repair shop. I no longer feel safe driving it. The repeated failures of the hybrid/electrical system, cooling system, and critical safety sensors, along with evidence of improper assembly, represent a significant safety risk. I request that the federal safety agency investigate these defects, as they appear to indicate a broader safety issue with this model.
