I'm new here. i have a 2010 Infiniti G37X Sedan. I just bought the car yesterday has 86k miles. Anyways i notice when using manual mode. Whenever I WOT the car when I reach third gear or so. The car transmission goes into DS mode instead and a key symbol shows up on the cluster? At this point there the car won't accelerate it can only rev until I put into "D" and I can accelerate. When I casually drive and shift it doesn't happen. Only when I drive it hard. Anyone had a similar issue? FYI no other lights show up, no SES nor anything else.
