I have a 2024 Lexus TX500h Luxury and drive both freeway and city. The best and average I a seeing is 21.4 MGP. I took it in to dealer and they hooked it up and said it is running properly. With the advertised MPG at 27/28 that is 20% below expected and most of the time even driving thought parking lots is in gas mode. Looking at the TX350 Luxury is rated at 21/27.
Is there anyone with the same problem?
