1. A system for a vehicle comprising:
a plurality of sensors onboard the vehicle, wherein a first sensor of the plurality of sensors is configured to detect lane markings on a roadway; and
a controller configured to:
store data from the plurality of sensors; and
in response to receiving an indication indicating a misdetection of lane markings on the roadway based on data received from the first sensor:
execute in parallel a plurality of procedures configured to detect a plurality of causes for the misdetection of lane markings, respectively, based on the stored data;
isolate one of the causes as a root cause for the misdetection of lane markings; and
provide a response for mitigating the misdetection of lane markings on the roadway based on the root cause for the misdetection of lane markings.
