On XXX at approximately 630pm during rush-hour traffic crossing the XXX on [XXX], my 2024 Jeep Grand Cherokee Limited L (11,800 miles) the brake pedal went to the floor and the vehicle would not stop normally. The vehicle was towed to the dealer. This created a dangerous situation in heavy traffic with my child in the car and could have easily led to a collision. The vehicle was promptly taken to the closest authorized Jeep dealer. They diagnosed a Brake Vacuum Booster failure along with Diagnostic Trouble Code P057B-00 (Brake Pedal Position Sensor related). I have video footage of the symptom occurring and photos of the repair diagnosis. This is a new vehicle with very low mileage, and this unexpected failure raises serious safety concerns about potential defects in the brake system. I am requesting that NHTSA investigate this matter to determine if it affects other 2024 Jeep Grand Cherokees. Vehicle Information: • Make/Model/Year: Jeep Grand Cherokee 2024 • VIN: [XXX] • Mileage at time of failure: 11,800 miles • Date of purchase: 11/1/2024 No injuries or crash occurred, but the safety risk was SIGNIFICANT.

Significant electrical issues. Screens randomly turn off and flicker which prevents driver from being able to see vehicle status including speed. Vehicle also has built in charge pad which over heats and concerned could lead to wires melting and fire. Vehicle has spent multiple weeks at dealership for electrical issues but no solution has thus far been found. Viddeo shows flickering but shut off happens randomly and have not been able to catch on video. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

No warning lamps were displayed relating to the recall. I was hit from behind while driving between 60 and 70MPH. I lost control and spun around twice before violently hitting a guard rail, perpendicular to the driver's side of my vehicle. The side/door airbags failed to deploy. My neck was thrown into the seatbelt and door. I suffered from partial vocal cord paralysis, tinnitus, dysphagia, loss of hearing, pain, and other symptoms due to the impact; my sternocleidomastoid and associated nerves being primarily affected. As a result I was out of work from May 13th, 2026 to July 3rd, 2026. I was not aware or notified about any recalls until after my accident. My vehicle was totalled.

2024 Jeep Grand Cherokee L Summit Reserve was parked before a snow / ice storm and when we went to drive it 5 days later, after the storm, it would not move and made a loud explosion noise when I pressed the accelerator. I immediately turned the Jeep off and went to look underneath to see if I could see what happened. The rear brake pads and calipers were blown off, along with a bunch of broken parts and the air ride suspension was at its fully extended height. It's been to 2 Jeep dealers who can not explain what happened and Jeep says there is nothing they can do. We have only owned this Jeep, which was purchased new, for less then 20 months when this happened. If this had happened while driving, we could have had an accident and been severely injured. The Jeep is available at this time to be inspected. No lights were on prior to this happening.

All lights came on when starting vehicle. Had no power steering, blind spot monitors failed, etc.
