“I am contacting you to request immediate corporate assistance regarding an outstanding safety recall involving my 2021 Land Rover Discovery. MY VIN: [XXX] I would like this matter escalated to a Customer Relations supervisor or regional representative who has the authority to address the recall, coordinate with the dealership, and ensure that an appropriate resolution is provided. I've tried to raise the following with my dealer service department, but they have denied the service action in within range. If you could confirm that additional information you need from me, I plan to accommodate in a timely manner. Please provide the following: 1. I've attached the Recall # N572v2m which outlines my VIN in the range. 3. The current status of the required recall remedy and parts availability. 4. A timeline for completing the recall repair. 5. Assistance with transportation or a loaner vehicle if the vehicle cannot safely be driven or must remain at the dealership. 6. A corporate case number and the name of the individual responsible for following up. I would appreciate a prompt response and a clear plan for resolving this safety-related matter. Thank you, [XXX]”

“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…”

“Supplement / update to prior NHTSA complaints regarding my 2021 Land Rover Discovery MHEV (VIN: [XXX] y prior complaints, Jaguar Land Rover has issued Recall 26V248 for DC/DC converter failure leading to loss of propulsion in 2021–2024 Land Rover Discovery MHEV vehicles. My vehicle experienced the same real-world failure condition: sudden loss of propulsion in traffic with my children in the vehicle. Jaguar Land Rover corporate has stated my VIN is not included in the recall population despite my vehicle being a 2021 Discovery MHEV and experiencing the same defect condition. I am submitting additional documentary evidence from Jaguar Land Rover Portland showing that during the repair process: * I was advised the vehicle would only run while connected to external jumper power and would shut off once that external power was removed. * Two days later, I was advised the installed battery would only charge to 6 volts and that another battery was needed to continue testing. These communications raise concern that this failure event involved broader electrical consequences and further support that my vehicle experienced the same defect condition described in Recall…”
