A method of alerting a driver of a vehicle is provided. The method includes: receiving conditions data from one or more collision avoidance systems; determining an alert mode based on the conditions data; receiving a fault status indicating a fault of at least one of a haptic alert device, a visual alert device, and an auditory alert device; resetting the alert mode to an override mode based on the fault status; and selectively generating an alert pattern for at least one of a haptic alert device, a visual alert device, and an auditory alert device that does not have a fault based on the override mode of the alert mode.
