RL: The engine control module in the subject vehicles is equipped with software to manage the
emissions systems. Due to improper programming in the software, the emissions monitoring
system may clear the system test results which can result in a vehicle not being able to
complete emission testing/smog checks. Additionally, the improperly programmed software can
result in incorrect oil pressure under certain conditions which can cause check engine light
illumination, harsh engagement when shifted into Drive, and, in some cases, automatic
transmission clutch damage.
