Um so everyone here is aware that they bought a 490hp go cart right? It's a machine just like every other car on the road that has moving parts that sometimes clank. Shoot mine is real bad but I drive around in dynamic mode with the radio loud enough to cover the exhaust note. And even with the car totally quiet I have yet to have a female passenger say anything about the clank. They do appreciate the quickness of the top function though. Plus first year of any car is going to have its issues, I'm just not convinced that noises or rattles are actually issues. High five on devoting that much energy to having the dealer correct it though. Prolly need a new set of rear tires soon so I'll check to see what the latest and greatest fix is at that visit.
Imthemap, you almost had me believing you until you made that ludicrous claim about getting the radio to play loud enough to cover the exhaust note in Dynamic mode.
That really isn't possible now, is it? True up!
Well I took it back to the garage and low and behold, one of their demonstrators had exactly the same clunking noise. It appears that this a 'feature' of the car and is not thought to be an issue. I would be interested to hear whether anybody else on this bulletin board is hearing the same 'clunking' noise: (i) when a gear is selected from stand still or (ii) when the gearbox is changing down when in slow moving traffic. Look forward to hearing from you.
I have exactly the same issue and my dealer can't figure it out at all. It's so bad that I have to depress the brake harder to stop the car from moving forward.
