I've got a 2000 Accord. I recently started hearing and feeling a hard knocking/clunking noise at the front-center of the car during the correct after a left turn. My trustworthy mechanic told me the subframe is rusted out on the right side and that it isn't safe to drive until the subframe is replaced (he also said he's seen several of these this last year). He suggested that the cause is that the hose leading away or down from the air conditioner is too short, and leaks directly onto the subframe. There is *no* recall on this problem currently. I've done some Internet research and there is some buzz about this, but not as much as I was hoping for. I'm wondering how to present this to the Honda dealer in order to have Honda pay for this serious and dangerous defect, which also nearly devalues the car completely. Any ammunition (in the form of information) is greatly appreciated!
