Just picked up a 2023 NX 350h last week. My 2017RX gives me mpg after reset, after refill and current trip. I see in the NX when I shut off the engine in the multi information display under the speedometer it gives me current trip. What does the MPG display represent in the MID while driving? Lexus told me after reset. Mine showed 30 mpg. I got gas drove home about five easy miles it it went from 30 mpg to 40 mpg so defintely not after reset.
