Example complaints

Electrical system: “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. …”

NHTSA complaint #11732006, filed 2026-04

Other or unknown: “After 2000 miles of driving, I received a warning that I had reduced traction and needed to drive with caution. When I took vehicle to dealer they determined the “initial configuration was not complete”.”

NHTSA complaint #11436143, filed 2021-10

Transmission and drivetrain: “This vehicle should be considered as a drive at your own risk vehicle. Engine randomly fails to start using push button start in coordination with pressing on the brake pedal. Dash and gages indicated all electrical systems were on and no warning symbols were displayed. Repeated attempts by owner to start vehicle failed. Attempts using remote start app erroneously indicated that the vehicle was already in operation. Fail-to-start generally existed for 2-4 hours before the vehicle would randomly start. …”
