My 2012 M37, with the upgraded sound system, has a rattle in the doors when songs with relatively heavy bass are played at more than about 60-70% of the maximum volume. The rattle is so significant that it almost sounds like the door speakers are blown. Mechanics at the dealership tested other cars on their lot when they learned of my complaint, and informed me that all the other cars have the same issue.
If true, this is a design flaw in the new M class Infiniti -- at least I can think of no other answer.
The dealership was great -- they kept the car over a week, working to fix the problem. They were unable to fix the problem, however. Accordingly, Infiniti sent out a specialist to look into the problem. His report indicated there was no problem, notwithstanding that both I and the dealership techs clearly heard the buzzing. It's unclear to me whether he didn't hear the problem, or if he is saying that this problem is somehow acceptable based on Infiniti design parameters -- he has refused to speak with me, according to the customer service rep at Infiniti with whom I've been speaking.
This is beyond disappointing. I paid extra for the upgraded sound because sound is important to me. For Infiniti to refuse to address the problem, and even to refuse to do me the courtesy of having the specialist that looked into the issue discuss his findings with me, speaks to a lack of concern for the customer.
