2019 Lexus RX 350
TSB Document:
Affected Component: ELECTRICAL SYSTEM
- Summary
- 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.
