INCIDENT SUMMARY: On January 9, 2026, at approximately 1:30 PM, while traveling at 50 MPH in North Carolina, the vehicle experienced a sudden, catastrophic engine seizure without any prior "Limp Mode" warning or Check Engine Light. This resulted in an immediate, total loss of motive power in active traffic. I was forced to navigate a dead multi-ton vehicle across lanes without power steering or vacuum-assisted braking, narrowly avoiding a high-speed collision. TIMELINE & NEGLIGENCE: This vehicle was purchased from an independent retail dealer on December 20, 2025—less than 21 days prior to this life-threatening failure. The vehicle was sold with an "Open" status for Safety Recall 23V‑707. The failure occurred exactly as described in the recall’s warning: a catastrophic stall at speed. TECHNICAL EVIDENCE: A non-invasive borescope inspection of the cylinders has confirmed the presence of metallic "silver chunks" (sheared bolt heads) and "half-moon" impact marks on the piston crowns, indicating a total timing failure and internal mechanical collision (piston-to-valve contact). REQUIRED REMEDY: This incident is a direct manifestation of the safety risk documented in Recall 23V‑707. Per BMW Service Bulletin SIB 11 09 23, the presence of sheared bolt heads and seized internals constitutes "Catastrophic Consequential Damage." I am filing this report to ensure federal oversight of BMW North America’s obligation to provide a complete engine replacement, as the safety defect was present at the time of sale and resulted in a near-fatal incident within 300 miles of ownership.

While traveling at night on the toll road between Washington, DC and Pittsburgh, PA, the vehicle suddenly shut off without warning. Power was lost completely, including power steering, while in motion on a major freeway, creating an immediate and severe risk of collision for us and surrounding motorists. Although the vehicle did restart, it stalled again shortly afterward while still on the toll road. The failure repeated when decelerating on the highway or coming to a stop after exiting. At no point were there warning lamps, check-engine lights, messages, or reduced-power mode indicators prior to the stalls; the shutdowns occurred without any advance notice. The vehicle was towed to an independent BMW-only repair shop in Pittsburgh. Their initial assessment indicated a high likelihood that the failure involved the VANOS assembly bolts, though the engine was not disassembled at that time, so the diagnosis could not be confirmed with certainty. Because the shop did not have immediate availability, we were asked to transport the car home until they could perform a full repair. After sitting for several weeks, the car was towed back for further inspection, at which point the shop discovered that a VANOS bolt had likely sheared off and caused irreparable damage to the engine. Our only options now are to replace the engine or scrap the vehicle. The vehicle remains in Pittsburgh, PA in our possession and is available for inspection upon request. At this time, the failure has not been reproduced or confirmed by a BMW dealer, nor has it been inspected by the manufacturer, police, or insurance representatives. Importantly, there is an existing recall on VANOS bolts for the 328xi station wagon, but our vehicle’s production date ([XXX]) falls just outside the recall window of October 1, 2009–August 4, 2011. Notably, for the sedan body model, the recall window was extended until December 6, 2011. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
