On [XXX], while driving my 2023 Jeep Grand Cherokee L on the [XXX] , at approximately 65 mph, a ring (like a washer) detached from the brake pedal. This caused the vehicle to suddenly lose braking capability. Right after I attempted to brake the vehicle on the highway, the ABS light, brake assistance light, braking distance automatic light, and traction control lights all illuminated on the dashboard, and the vehicle required immediate assistance. The brake pedal did not respond normally to pressure. I had to downshift rapidly to slow down and exit the freeway safely. Once in a safer area, I was finally able to stop the vehicle by applying a lot of pressure to the pedal. This dangerous failure put myself and other drivers at serious risk of an accident. Due to the severity of the issue, I immediately called a tow truck and had the vehicle taken to the authorized Jeep dealership in Tustin for repairs. I had previously experienced another major repair (rear axle joint binding) that took approximately 64 days when the vehicle had around 30,000 miles. The current incident occurred at approximately 52,000 miles. I reported this safety issue to Jeep Customer Service and received Reference Number [XXX]. This is a serious safety defect involving the brake system that could have caused a crash on the highway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I had my brakes flushed by my local dealer in June 2025 at about 31,000 miles for routine maintenance. I was traveling to York, Pa from Gravette, AR in September of 2025. All systems on my Cherokee had worked flawlessly on the trip, as they had since its purchase new in the Fall of 2023. On a very curvy, hilly road in the Cactocin mountain area, I was braking often. The ABS system warning light came on, as well as messages that the automatic collision control, lane departure control and adaptive cruise control were disabled. I noticed immediately that my brake pedal felt mushy and went nearly to the floor. Basically it felt like an old car with no power brakes. I proceeded to Gettysburg. When I restarted the car the error messages had cleared. I continued but after a few stops all of the error messages returned. When I got to York, still Thursday, I went to Stetler Jeep dealership and asked to have my Jeep looked at. The service clerk said no because I had no appointment. I asked to at least do an Obd2 scan so I know what the problem is. He said no, it can’t be done without an appointment. was told not until next Wednesday. I only planned to be in York until that Sunday. Between York and Decatur, IN on way home to Arkansas the warnings reoccured 3 more times, a total of 5. When stopped with my foot on the brake, when no errors showing, I would sometimes hear a clicking noise behind the steering wheel and feel it on my foot. A dealer in Indiana and my local dealer in Fayetteville, Arkansas could not find anything wrong. Those error messages have not appeared again without any repair. In December, my brakes were dragging and the brake waning light came on several times, then remained on. I could release the brakes by pumping them. My local dealer flushed brake system as the repair and warning light was gone. Two days later, brake system warning light is on again. I am taking it back to the dealer again even though brakes seem to be working fine.

Updates to the case#11679471. Since my initial report, Jeep arranged for an independent technician to retrieve and review the Event Data Recorder (EDR) from our vehicle. While Jeep has not shared the expert’s conclusions with us, we obtained a copy of the raw EDR data file from the same tech (attached). Based on the EDR data: 1. The brake pedal was fully applied approximately 0.4 seconds before impact and remained depressed. 2. The vehicle’s deceleration was only ~0.5 g, significantly below the expected ~0.8–1.0 g for dry asphalt conditions. 3. The ABS did not engage, indicating that hydraulic brake pressure was not reaching the level required to approach wheel lock. 4. The Automatic Emergency Braking (AEB) system was “On” but did not engage. 4. The Advanced Brake Assist (ABA) activated only ~0.3 seconds before impact, too late to reduce the stopping distance. 5. No DTC (diagnostic trouble codes) were recorded at the time of the event. These EDR findings indicate that the driver executed proper emergency braking, but the brake-by-wire system did not deliver sufficient hydraulic pressure to achieve normal deceleration. This may suggest a potential electronic or hydraulic brake system defect. The vehicle remains undrivable, and we have been declined by two separate Jeep dealerships to obtain an effective inspection or repair. Given the direct connection to FMVSS 105 (Hydraulic and Electric Brake Systems) requirements for service brake performance, we respectfully request that the federal safety agency treat this case as an urgent safety concern.

On July 16, 2025, at approximately 6:10 PM, I was driving home on the highway at around 65 mph when I attempted to brake. The brake pedal went completely to the floor, and no braking occurred. At the same time, the following warning lights and messages suddenly appeared on the dashboard: - “Service Park Brake” - “Service ABS” - “Service Electronic Stability Control” - “Auto Hold Unavailable” - “4WD System Temporarily Unavailable” I was able to maneuver the vehicle into the emergency lane without colliding with other vehicles or causing a high-speed rear-end accident. The vehicle came to a gradual stop but would not restart afterward. This failure occurred without any prior warning and posed a serious risk to my safety and the safety of others on the road. I do not know how an accident was avoided, as the failure was sudden and could have resulted in a tragedy. The vehicle is a 2-year-old Jeep, with approximately 36,000 miles, and has been regularly serviced by Jeep, most recently about one month prior to the incident. After the incident, I had the vehicle inspected by a Jeep dealership, which confirmed the failure and identified a defective brake control module as the root cause. The component is available for inspection upon request.

This complaint is an update to my previous complaint #11679471 submitted on August 8, 2025. Please consider this as additional information to the original case. Since my initial submission: Second Dealership Refusal: I attempted to bring the vehicle to a second authorized Jeep dealership for inspection and diagnosis. They refused any service, stating they would not inspect or repair the vehicle. This is now the second dealership to reject the vehicle after the incident. Obtained Diagnostic Printouts: Despite refusing service, the second dealership was convinced to provide printed codes from the vehicle. These codes show multiple system errors recorded at a very low vehicle mileage, including communication failures with the ABS control module, brake system internal failure, and CAN bus errors. These indicate potential electronic or computer system faults that could have occurred immediately before or during the brake failure. Manufacturer Warranty Issue: Immediately after the incident, Jeep opened a warranty case #93917003 for the vehicle. However, during subsequent communication, I was informed that this brand-new vehicle has no manufacturer's warranty at all. This is extremely concerning, as the vehicle was purchased new with only minimal mileage and no prior damage or modifications. Vehicle Condition: The vehicle remains undrivable and unsafe to operate. Jeep or its authorized dealers have performed no corrective action. Given that this was a brand-new vehicle with extremely low mileage purchased solely for personal family travel, and that both authorized dealerships have refused to address a major safety defect, I am requesting that the federal safety agency treat this as an urgent safety matter. The refusal to investigate by Jeep dealerships, combined with the unexpected claim that there is no manufacturer warranty, leaves this defect unresolved and poses an ongoing safety risk if similar failures occur in other vehicles.

While driving on the Belt Parkway towards Coney Island in stop-and-go traffic at approximately 25–35 mph, the vehicle in front slowed and came to a stop. The distance to the vehicle ahead was more than two car lengths. The brake pedal was fully depressed, but the vehicle did not decelerate adequately to come to a complete stop. The driver's record is clear of any car accident All forward collision warning alerts were sounding, but the ABS and automatic emergency braking (AEB) did not activate. There was no tire screech or pulsation from the brakes. The vehicle slowed but continued to move forward, resulting in a low-speed frontal collision. After the collision, the vehicle refused to move until the engine had been turned off for several minutes. Airbags did not deploy. This incident happened on a brand-new vehicle with only 318 miles on the odometer. We immediately contacted Jeep Corporate and opened a safety case. However, the first authorized dealer we visited, as was told by the Jeep advisor at 111 58th St., Brooklyn, NY 11220, refused to inspect the brake, ABS, or AEB systems under warranty, after we said that we have case number from Jeep and we need to read the computer while it still has information about the acident in the memory. Also were refused to provide a written denial, and directed us to a collision center instead, which repairs only the body but doesn't have equipment to read the car's faults. Due to this refusal, Jeep Corporate initially closed our case without resolution or notification; we had to insist on having it reopened, as the issue wasn't investigated. We are aware that Jeep models from 2024–2025 (though not exactly this trim) have had recalls for ABS, brake module, and electronic stability control issues, and these systems share similar or identical computer modules across model lines. Given these known issues and the seriousness of a complete brake system failure on a new vehicle, I believe this warrants immediate investigation by the federal safety agency.
