I bought a new 2019 Porsche Macan S from Porsche Centre Melbourne. From day one as I accelerate at low revs a vibration can be felt through the accelerator and passenger’s foot well. Porsche has told me it’s a software issue and is investigating. Does that sound right? The say they've ruled out the gearbox and drive shaft.
It could well be a software problem, as the Porsche people have told you, so let the experts do their investigations, and hopefully come up with a fix. There’s no point in trying to second-guess what it might be.
