Honda Odyssey motor mount problem

Same story–a little higher mileage. I suspect however, that this has been going on for some time. We’ve had it in over and over for the vibration and noise up front and were told each time that nothing could be found. This from three different dealers (we leave home for the winter). Even bought the extended warranty on this vehicle and, conveniently, the problem was found just after the 120K warranty expired. Our estimates are $820 for the front and $710 for the rear. This car has been nothing but a headache and we are done!! No more Honda. Does anyone know how unsafe it is to continue to drive it until we decide what we want to trade for? Need to go back up north for the holidays. thanks
