An inherent fault is an issue affecting all or a significant number of specific vehicles, which could be a design issue or manufacturing problem that is causing the vehicle to not function correctly or has the potential to cause a problem. A manufacturer recall is where the manufacturer contacts the owners of affected vehicles in order to repair or replace the affected components. A recall may be due to an inherent fault or it may not - manufacturers have recalled vehicles where no fault has been apparent to owners but a flaw in the manufacturing process has subsequently come to light and affected vehicles are recalled to prevent any issues.
