IV. Background

Lexus recently identified a momentary sensation that some drivers may consider unusual following the upshift into 3rd gear while in Economy ("ECO") mode. As part of our continuing efforts to provide superior customer satisfaction and to optimize vehicle performance, Lexus will re-flash the Engine Control Module (ECM) calibration in certain early 2013 model year GS 350 to eliminate this condition from occurring.
