When I start the engine it starts rough and when I'm driving in any gear(cvt) transmission the entire car begins to vibrate really badly, I changed the spark plugs, cleaned the mass airflow intake sensor and the throttle body, oil used is 0w-20 for now with 64k on it. I noticed when I go down a hill a put it in neutral it smooths out completely. I will admit I was overdue for an oil change by 10000 miles but even before getting it changed no vibrations until aftewards. I also recently changed the tranny fluid as well, I can't figure this out for the life of me. I know there are many causes to this but can you possibly narrow it down ? Any help is appreciated, thanks

I have aprox 55 dents on my hood, roof and trunk from acorns. (very noticable, like hail damage $580 worth of damage) I have parked him my driveway for over 7 years and NONE of my cars have recieved even A Dent. Its obvious this car is made out of soft/thin metal! I think Honda should be liable due to it being a manufacture defect...why should i be responsible for a poorly made car? Anyone else with the same issue?

this car was recently in an accident that caused the air bag to deploy, we installed the new ones and figured it'd reset on its own after installation that wasn't the case maybe we missed something?

There is a rotating knob thing which you turn to align with the ON and OFF positions;; however, there is no indicator line whatsoever on the rotating thing that aligns with the ON and OFF positions. The directions in the owner's manual are useless.
