My father owns a 09 G37xS 7AT Sedan and last weekend I drove it for about an hour on paved country roads. It was flawless, bit envious actually of that 7 spd gearbox.
It has 115,000 KM on it and has not even so much as hiccuped on him before. He gets it regularly serviced.
He called me yesterday, and after a short talk he explained to me what sounds like it had gone into limp mode while he was driving it. Wouldn't rev over 2500. No warning lights however and he pulled over after realizing something wasn't right and restarted. Limp mode was gone and he still had no warning lights.
He said he wasn't pushing it and that it wasn't running hot. I am not sure what to say other then for him to go get codes pulled and go from there?
Has anyone had this? Can limp mode just glitch in sometimes?
