NHTSA Complaint #11707138 — 2016 BMW X5

Subject: Consequential Damage and Failure of Remedy regarding Recall 24V-608 Incident Description: "I am reporting a failure of the manufacturer to provide an effective remedy for Safety Recall 24V-608 (Electric Water Pump) and subsequent consequential damage to the High-Voltage battery system. In September 2023, at approximately 78,000 miles, this vehicle exhibited 'Drivetrain Malfunctions' including Fault Code 0x222626 (EME: internal fault - active short circuit requested) and 0x22271C (Overvoltage in intermediate circuit). The BMW dealer (Fields BMW) failed to diagnose the root cause and instructed me to 'keep driving'. Since the release of Recall 24V-608, it is clear these 2023 faults were early indicators of the coolant pump short-circuiting. This persistent electrical instability has now resulted in a permanent failure of Cell Supervision Circuit #3, causing the high-voltage contactors to open and leaving the vehicle disabled. The dealer is currently attempting to charge for diagnostics and battery removal. I am asserting that the lack of a timely remedy for the coolant pump (which was only recently shielded per the recall) caused a power surge that 'fried' the internal battery circuitry. This is a safety issue as the vehicle experienced a sudden loss of propulsion while in motion. I request that NHTSA investigate BMW’s refusal to cover battery failures caused by the electrical interference of the recalled coolant pump."
