My car is vibrating so bad at 50-53 miles per hour and 1500 rpm's that I cannot drive it for any distance without my hands turning numb. Yes, the dealership can easily duplicate it (and at different speeds too). Diagnostic codes have come up with a 'bad' motor mount. Both the front and rear have been replaced, but nothing has been resolved. The Honda district service manager agrees there is a problem and now 'THE' techician is being 'flown in' to look at it. I understand to increase the gas mileage, changes needed to be made, but it seems like they haven't been perfected yet.
