This could be caused by a number of things – loose components, worn out shocks, body damage. mostly, it is the result of tires that are under-inflated. your 4th question sounds like you might have tires that aren't fully inflated. if so, this would be the cause of feelings like these when starting your car and driving off. i would recommend having your back window checked to see if there may need to be some other service performed post attempted repair on the wind shield wipers as prevention against future issues with over sprayings or water leaks into one's interior seating area while parked in snowy or rainy locations for long periods of time.
the important thing to remember is that your first priority should always
why is my car shaking when i start it?
1. ignition timing is off.
2. engine alignment is off due to worn engine mounts, which can be problematic if wheels are pointing in opposite directions.
3. drive train components are malfunctioning including belts, hoses, and pulleys; this problem would be uncommon unless it's an old model with weak or damaged parts (see below for possible causes).

should i be worried if my car is shaking?
it is possible that you have a tire issue, a loose bolt, a broken suspension spring, or any number of other issues. the best thing to do is take your car to an expert who can make an informed decision about what the issue might be. you can find mechanics online in most major cities with the tools and expertise to determine if there's a more significant problem worth fixing right away.
if you suspect there may be some sort of internal engine damage going on inside the shaking, then it's best not to drive anywhere besides taking your car back where it came from or seeing someone who knows what they're doing about engine repairs. it could potentially lead to catastrophic destruction if something breaks free while you're waiting at a
