NHTSA Complaint #11712866 — 2024 LAND ROVER RANGE ROVER

Subject: URGENT: Investigation Request – Systemic Loss of Propulsion in Jaguar Land Rover (JLR) Vehicles (2017–2026). 1. Description of Defect I am formally reporting a critical, life-threatening safety defect involving the Powertrain Control Module (PCM) and the Fuel Pump Driver Module (FPDM) in Jaguar Land Rover (JLR) vehicles. These modules suffer from spontaneous software "resets" or "reboot" loops during operation. When the PCM resets, it severs communication with the fuel system, causing an immediate and total loss of propulsion (motive power). 2. Safety Hazard and Real-World Impact This defect triggers without warning at highway speeds, resulting in vehicles stopping abruptly in high-speed lanes. This creates a "sitting duck" scenario, rendering the vehicle unable to move to a shoulder and significantly increasing the risk of catastrophic rear-end collisions and multi-vehicle pileups. Reported incidents include near-misses and accidents directly attributed to this sudden stalling. 3. Timeline of Manufacturer Awareness (2017 – Present) JLR has been aware of this specific PCM/FPDM communication failure since at least 2017. Internal documentation, such as NHTSA Technical Bulletin SB-10095121-1020, identified short circuits in the PCM/FPDM line for 2017 F-PACE and XE models. Subsequent bulletins, including MC-10218879-0001, admit that software "flashing" is ineffective and that FPDM hardware replacement is often required. Despite nearly a decade of internal knowledge, JLR has failed to initiate a comprehensive global safety recall for all affected VINs, opting instead for localized "Service Actions" that do not permanently resolve the hardware instability. 4. International Context and Manufacturer Inaction The Chinese State Administration for Market Regulation (SAMR) has already summoned JLR officials regarding these stalling failures. However, JLR has not provided a verified, permanent solution. 5. Demand for Action We demand an immediate, multi-agency
