Hi, have a honda odyssey 07. I just I just got an alignment done on Tuesday night. I think it drove okay. I sent my car to Costco last night to get 2 new front tires replaced. Took the local road home last night and didn't notice anything wrong. Now I am driving to LA from SF. As soon as I hit the freeway, I noticed my car vibrates uncontrollably when I accelerate at the speed btwn 65-7mph. However, it seems okay when my feet are off the gas pedal. Any input ? Should I stop driving? I am driving w/ 4 kids . I would like to know if my car is safe.
