I am reporting a serious safety failure in my 2025 Jeep Grand Cherokee L (1,483 miles). On XXX, the vehicle was parked with my wife and young children inside. Upon starting it, the vehicle would not shift into gear, the steering wheel locked, and the front windows stopped working. The lane departure symbol lit up during the failure, and the vehicle would not shut off through normal controls. After two hours, we shut it off by disconnecting the battery. When restarted, the check engine light and other warning lamps came on, and the vehicle began shaking and rattling. No crash occurred, but with steering locked and children in the car, I had no way to safely disable the vehicle for two hours. This could have caused loss of control if it happened while driving. No prior warning signs occurred before the incident. The vehicle has not been inspected by a dealer or repair shop, as no certified Jeep dealership exists on Lanai, Hawaii, where I reside; shipping the vehicle requires barg transport to XX or XXX. The vehicle is available for inspection on request and is currently not in use. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I bought my truck march 2025 in August while putting groceries in the trunk the trunk started coming down on me I took it to the dealership the hydraulic fuel was low had I been a child the trunk probably would have shut completely on them, may 2026 both batteries went out the main batteries and the auxiliary battery june 21 the fuse array box went out nothing on the door panel works the doors won’t lock the windows don’t work the trunk won’t work the seats won’t adjust and the dealership is trying to say that this box is only covered 12 months or 12000 miles

A trailer hitch was contracted as part of the vehicle purchase on December 20, 2025, and was physically installed by Southern Chrysler Dodge Jeep Ram in January 2026 as a fulfillment of that purchase contract. This installation was performed by Stellantis's own authorized dealer technicians. The vehicle has been configured and warranted for towing use since January 2026 — an explicitly marketed capability of this vehicle platform. A trip was scheduled for May 18, 2026 to tow a 12-foot rigid inflatable boat (yacht tender) weighing approximately 600 pounds on a trailer from XXX to Fawcett Boat Services in XXX — a route of approximately 150 miles traversing [XXX] in heavy traffic at approximately 70 mph. The appointment at Fawcett Boat Services is verifiable. The boat's location in [XXX] is documentable. The air suspension failure occurred on May 17, 2026 — one day before this towing trip. The trip was canceled as a direct result. Had the failure occurred on May 18, 2026 during transit on Interstate 95: —The spontaneous asymmetric rear suspension collapse — right rear corner dropping without warning at 70 mph — would have subjected the hitch coupling to vertical and lateral forces outside its design tolerance —Trailer instability, jackknifing, or physical decoupling of a 600-pound loaded trailer at 70 mph in heavy interstate traffic is mechanically foreseeable —A decoupled trailer carrying a rigid boat structure at 70 mph in heavy traffic is a lethal projectile — the foreseeable consequences include multiple vehicle collisions and loss of life Stellantis marketed this vehicle as towing-capable. Stellantis's dealer installed the hitch. Stellantis knew — through its own published Technical Service Bulletins — that the Quadra-Lift system was prone to spontaneous failure at highway speed.

On April 20, 2026, my 2025 Jeep Grand Cherokee L was involved in a crash due to a sudden and complete brake failure. At the time of the incident, the vehicle was in the custody of an authorized FCA dealership. An employee of the dealership was operating the vehicle when the brakes completely failed to respond, resulting in an accident. FCA US LLC Special Investigations conducted an inspection (Case #[96529168]) and stated they found no physical evidence of a manufacturing defect or component malfunction. However, the mechanical or electronic failure was severe enough to cause a crash while being operated by a professional dealership technician. I am filing this complaint because sudden brake failure represents an extreme safety hazard to the public. The manufacturer has denied assistance, and independent federal oversight is required to determine if a software or hydraulic defect exists in this model year.
