Default What would cause this problem?

If this in the wrong thread, please move it, but I think it's correct.

I have a 2015 IS350 Fsport. I got it in September, it has 4300 miles on it. It's not a weather issue as I'm in south florida and it's between 75-85 now.

No issues or problems previously, but on Tuesday night I was driving home at 645pm (Lexus service closes at 6) and all of a sudden the whole car starts shaking as I was driving about 35-45 mph on a street. No lghts came on the dash, but it was feeling like the engine lost power and when I stepped on gas, it barely got past 45mph but the whole car was violently shaking (like a roller coaster that went off the track). After a minute, the transmission light came on and started blinking. While driving, I called Lexus but service was already closed, nothing I can do, but bring it at 730am. I said, I don't know If I will even make it home. I ended up getting home. I made an online appointment for Wednesday morning and left my house to drive over there.

As soon as I got in car, the transmission light was on solid now, and it said "TRAC OFF" on the dashboard as I was hearing bang's from something in the engine while driving less than 5 mins to Lexus dealer.

I got a ride to work and the service advisor called and said the tech worked on your car but didn't find a problem. He saw that engine misfired but didn't see anything else. Reset the error in the computer and test drove the car but didn't see anything else. (I'm like WTF, there is a problem). But they said there is nothing they can do except record the problem on their computer and next time it happens bring it back in and they can look at the data.

Does this sound right? Now. when I'm driving my car today, it feels like there is no punch in acceleration. I don't have any engine errors or messages on the dash or do I hear misfires anymore, but it doesn't seem like the same vehicle as 3 days ago.

What could this really be and what do I do?

Thanks
