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)

Dealer refused to cover DME that failed immediately after recall 24V‑608 work. In early June 2025, I contacted my local BMW dealership about an overheat notification I received while driving. They confirmed there was an open recall on the vehicle for a water pump connector (Recall 24V‑608). I had the vehicle towed to their location. They sent me a video walkaround that characterized everything looked good, except the water pump connector which had failed. Several days later, I was informed the recall repair had been completed but when they plugged in the new water pump connector, the DME shorted and they had to unhook the battery. Despite my best attempts to get this consequential damage covered as part of the recall work, BMW refused. I was told I had to come pick up the car as-is or pay for repairs. When I looked into the issue further online, I learned that if I had chosen to pick up the car, hook up the battery and attempt to start and drive it, I could have found myself stuck inside the car (electronic locks) with a DME that literally caused the whole car to start on fire. Thank goodness I didn't go that route. After further investigation into the recall issue (24v-608), I have learned the entire basis of the recall was risk of a "thermal event" caused as a result the faulty water pump connector shorting out. BMW never denied this when I brought it up. It is infuriating that BMW is suggesting the DME shorting out is not related to or covered by the water pump recall issue. A risk of thermal event is stated in the recall notice, and the DME literally shorted out DURING the recall repair work. They quoted me something like $5,000-7,000 to have the car drivable again. I'm at a complete loss.

DRIVE TRAIN MALFUNCTION. On June 25th 2025, for the second time I got this Drive Train Malfunction Issue on my 328i 2012 Model. The car just stopped in middle of road ( thank GOD not on a freeway ; otherwise, this would have resulted in multi car accidents and could have costed people's life including mine ). The car just died and STOPPED all of a sudden in middle of road and when I tried to start it, it only crank's . After waiting for about 10 minutes, it started . I had exactly same issue earlier in July 2024 and that time BMW service found high pressure fuel pump to be defective and they changed that. I was told by my BMW dealer that certain model and year BMW has this issue and it is well know. But I do see BMW issuing to its customers or doing anything. If the car just stops without any warning to pull over etc. while you are driving is very serious is VERY SERIOUS and LIFE- THREATENING ISSUE . Imagine one is driving at 70 miles an hour on a busy freeway and car abruptly stops ( like my car did , twice in last 11 months, thank god not on freeway though) and there are several cars behind you driving at more or less at same speed; this will result in multi cars collision and multiple accidents and deaths. I request the federal safety agency to take this serious issue on priority basis and do something ASAP.
