Overview
Due to a software issue that has since been corrected, the software designed to continuously monitor
end-to-end communication between the safety-related ECUs in the vehicle can, in certain instances,
incorrectly and sporadically detect a potentially faulty communication, set an error memory entry and
trigger a shutdown of the power train, resulting in loss of motive power. To help prevent this from
occurring, high-voltage power electronics must be reprogrammed with updated software.
