I received my SQ4 a few weeks ago and like it, except for one issue: there is an annoying buzzing noise coming from the instrument cluster when I hit the accelerator. It's most noticeable at slow speeds when things are quiet and I push the accelerator lightly around 2-3K rpm. I brought it to the dealer twice and the technician who went on the test drive with me said, yes, that's an annoying noise. The response I received after the service was that this is normal noise from the injectors and that all Ghiblis do that. I did not hear the noise on any of the test drives I took. Has anybody else had an issue with that?
