vibration after acceleration ?
I have a 2014 ES. I start to notice two weeks ago that my car vibrates after I accelerate to merge into highway. Typically it takes me 3-4 mins from home to highway ramp. After I accelerate to merge with traffic and reach cruising speed at 70mph, my car would vibrate for 5-10 min. After that no more vibration. Any one know possible problem? I didn't do any thing to my car except regular oil change.

Does the car vibrate at the same speed and if so does it go away above or below that speed? Check tires for unusual wear patterns visually and make sure they're inflated properly.

I only have 5000 miles on my new tires and just did balance. No issues. The vibration doesn't go away no matter the speed, but it does go away after 5-10 mins.
Because it only takes me 3-5 mins to get onto highway, may be the engine is not totally warmed up yet?

Does the car vibrate while still? IOW is it the engine shaking? With A/C on or off?

Did you have the issue prior to the tire change?

I will check the tires. It could be out of round or could have manufacturing defect. I am only saying this because you have mention the vibration goes away after you are on the highway.

I was thinking that you may have snow and ice stuck in and behind the spokes of your wheels... but considering that it is summer and you are in California (?), that is likely not the cause.
If the vibration goes away after 5 or 10 minutes, I would agree that engine warm-up may be something to consider.

There are quite a large number of factors that may cause vibrations, obviously. Start with tires, as mentioned. Other simple ones: gas quality and fuel injectors (add a bottle of techron and see if it changes anything), dirty mass airflow sensor (try cleaning it- not hard to do but be careful in handling it). How many miles on it? If getting near 100k miles, oxygen sensors might be dirty or on their way out.
