Anyone note that their 2025 RS with 8 speed will not shift to 8th gear? Mine will once and a while if I use the paddle shift mode. Most of the time the display shows I've selected 8th but the transmission never shifts to 8th gear. In D (Drive) it will stay in 7th gear, 2200 RPM at 70 mph. In 8th it will cruise at 1800 RPM.
