I am filing a safety complaint regarding a sudden and complete loss of power event while driving my 2021 Land Rover Discovery. The vehicle experienced a DC-DC converter failure with no warning, resulting in a sudden shutdown. The engine lost power, critical systems went offline, and I was unable to shift the vehicle into neutral. The vehicle became immobilized in active traffic, creating a dangerous situation. This incident occurred without warning and left me with no ability to safely move the vehicle out of traffic or rely on normal emergency functions. This presents a serious safety hazard to both the driver and others on the road. The vehicle has been at the dealership since mid-January 2026. The dealer has stated that the DC-DC failure caused additional component failures. However, no root cause has been identified beyond “internal failure,” and I have not been provided confirmation that the system has been properly tested or that the issue will not recur. I am concerned that this failure can cause cascading electrical issues, including loss of the 12V system, impacting multiple critical vehicle functions at once. The lack of a clear diagnosis and verified repair raises concerns about reliability and safety. Given the sudden loss of power, inability to move the vehicle, and absence of a confirmed root cause or validated repair, I am formally requesting that the National Highway Traffic Safety Administration open a defect investigation into the MHEV/DC-DC system. This failure creates a significant safety risk, including vehicles becoming immobilized in active traffic without warning. The risk of recurrence without a defined cause is especially concerning and may indicate a broader issue.

While driving my 2021 Land Rover Discovery (MHEV) in active traffic, the vehicle suddenly displayed an “Electrical system fault – Stop safely” warning. Immediately after the warning, the vehicle lost power and shut down, leaving me stalled in traffic with no ability to safely move the vehicle out of the roadway. There was no prior warning, no gradual degradation, and no driver-caused condition. The shutdown appeared to be related to the 48-volt mild-hybrid electrical system, possibly involving the DC-DC converter or battery management system, which disabled critical vehicle functions. This failure created an immediate safety hazard. I was at risk of being rear-ended and had limited ability to safely exit traffic. The vehicle became effectively inoperable without warning, which is unacceptable in real-world driving conditions. What is especially concerning is that: •The warning instructed me to “stop safely,” yet the vehicle did not allow time or power to do so •There were no visible issues beforehand •The issue appears consistent with known Land Rover MHEV electrical failures •Software updates were present, but did not prevent the failure A sudden electrical shutdown in traffic poses a serious safety risk to drivers, passengers, and others on the road. This issue should be investigated for potential defect, recall, or mandatory repair, as it compromises safe vehicle operation.
