Hello I just bought this 2009 es350 with a little over 99k miles about a month ago. It's been running completely fine and everything works except the infotainment screen is broken and I need to replace it. I got it for 8000 from a private seller. About a week ago I was pulling out of a steep driveway and the bottom of the car hit the road and ever since then I've had this issue happen twice when trying to accelerate hard (about half throttle) in first gear. First time was when pulling out of a heavy traffic lane on the high way, I stepped on the gas to about halfway and this shaking happened. 2nd time I was trying to replicate the problem on video and it didn't happen for about 10 of the times I accelerated hard from a stoplight but it eventually happened and I caught it on video. Any ideas what it may be or any tips on how to diagnose the issue? I am going to a local mechanic Thursday morning to get it inspected. video of the shaking attached.

Something is seriously loose or broken. Wheel(s), suspension components, maybe motor mounts. You shouldn't drive the car.

Would the motor mounts be an expensive or long repair? Is this a common issue at all? My last car was a BMW e60 535xi and I had to get rid of it due to an issue that would have cost 5k to repair, could this turn into a huge issue too?

Not a common issue no. Taking a guess you may be looking at prior damage from an accident, or could be a repair done poorly. On inspection the problem will likely be obvious. I can't guess what the cost will be.

Alright hopefully it ends up being obvious and simple enough, will update when I get it inspected by the mechanic on Thursday.

All of FWD cars do this when spining the tires on rainy pavement. Mine also does this so no worries.

Oh wow I didn't realize but both times it happened were during the rain so you might be right, other than this the car idles completely fine and I can floor it while driving on the highway with no problems. Thanks for letting me know, I'll still get it inspected just in case but that makes a lot of sense.
