The contact owns a 2026 BMW X5. The contact stated that while attempting to start the vehicle, several warning lights illuminated, and the steering wheel seized. The vehicle was towed to the dealer, where it was diagnosed with an incomplete software update. The contact was informed that the software update needed to be performed. The vehicle was repaired. The contact was dissatisfied with the failure and the diagnostic result. In addition, the contact stated that the system should have reverted to the original software. In addition, the contact stated that if the vehicle was in drive, the failure could have resulted in a serious situation. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 3,000.
With 1900 miles since purchase, car became undriveable. Displayed warnings included “high voltage failure” and “drivetrain malfunction”. Car had to be towed to dealer.
The vehicle is exhibiting symptoms that are identical to those described in NHTSA recall 25v556 — water intrusion through the windshield and a-pillar area. The recall documents that improperly sealed windshields can allow water to enter the power distribution box and electronic control unit, leading to a short circuit and, in extreme cases, a thermal event even when the ignition is off.
