The contact owns a 2023 Land Rover Defender. The contact stated that while driving approximately 55 – 60 MPH, the vehicle suddenly shuddered and vibrated with several unknown warning lights illuminated and flashing before the vehicle abruptly stalled and lost power in the middle of the freeway. The vehicle lost steering and braking functionality and was unable to accelerate. The vehicle failed to restart. The contact stated that several vehicles almost crashed into the rear of the vehicle, and a semi-truck came to a screeching halt behind the vehicle. The contact experienced an extreme panic attack and severe anxiety during the failure. The Emergency Services were called to the scene and with the help of the Fire Department, Police, and Ambulance Services, the vehicle was moved from the roadway to safety. The vehicle was later towed to the local dealer who diagnosed the vehicle and determined that the DC-to-DC converter had failed and needed to be replaced. The contact was informed that the part was on back order and that the vehicle could not be immediately repaired. The manufacturer was notified of the failure. The failure mileage was 40,000.

While driving the vehicle warnings alerted me that the battery was low and to start the vehicle ( it was running as I was driving) then the alert changed to pull over when possible. At this time the power steering and power brakes started to fail by the time I pulled into a parking lot the vehicle completely died and I had to push it into a parking spot. I called Land Rover they towed it to a dealership. The dealership in Orlando Florida said that the DC to DC converter failed and that it would need a new one (but the part is on a back order because it’s a common issue and they have no idea how long it will take to get the part) it will take at least 30 days or more to get a new part. Before I managed to pull over in a safe location the steering became very heavy and the brake pedal got very hard and barely stopped the vehicle ( almost had a collision) and steering into the parking lot was extremely difficult.

While driving my Defender 130 at Highway speed a warning for a faulty electrical system light came on. Within a mile while I was trying to exit the highway, all electrical systems failed. I had a gearbox failure warning and the car went into neutral at highway speed. Power steering failed and I had to manhandle the vehicle off the road into a snow drift to get off the highway.

Lane assistance and power steering failed. There was no warning light or alarm. The warning light in the dashboard came on reading “Lane assistance not available” and “power steering resistance reduced” immediately when both systems failed. We were able to safely park, no one was injured. The car has been at the service center at the dealership for 10 days.

The power steering failed and the car was not drive-able. The warning light for no lane assist available also turned on. The vehicle was in-operable and left us stranded. This would have been a much bigger issue in the winter time, or if I was not at my home. I contacted Land Rover, who had me call LandRover road side to have the car towed to the dealership, since this occurred on a Sunday. They confirmed the issue of power steering malfunction. There was no warning that his was going to happen. It first appeared when we tried to start the car and it was not drive-able. Once at the dealership, I was made aware there was a service bulletin-not a formal recall- regarding this malfunction. It required two code updates (that I was unable to complete with attempt to update software prior to tow) and a battery reset. With this being such a significant issue, making the car in-operable, it was frustrating to hear it was a known issue that was not a recall. The dealership told me there were others in the area that had the same issue and were fixed, with out recurrent of the issue.
