Both times I was getting onto the highway/interstate. The first time the RPMs jumped to 5500. Out of all the cars I have owned, many of them with well over 100,000 miles, I've never seen this before.
So far it isn't look good for Hyundai if they are looking for a repeat customer. This is my first and most likely last Hyundai.

I just talked to the Hyundai technician at the dealer and they said they checked all through the engine and transmission and since they couldn't pull an error code (check engine light never came on) they couldn't do anything.
This weekend I am going to drive it around and try to recreate the problem. So far the smoking is not consistent at all with mine or my wife's driving habits.

That's pretty lame...not everything throws error codes...hey my door latch doesn't work...sorry, I didn't detect an error code.
It may be difficult...but if you're going to try recreate it try to see if you can have somebody record a video of it. Without a video, if you cannot recreate it in front of the mechanic I don't think they'll do anything for you.

Low compression or leaking rings would most likely not throw a code. They need to step it up and look into this. A compression test is not that expensive. Just take out the plugs hook up the tester and crank the engine.

I have a 2011 Elantra Limited and have experienced the exact same thing! On two occasions, once at about 14K and just today and just under 20K. I've been around cars my whole life and am pretty sure I can differentiate between burned oil and carbon. This is definitely oil, blue/whitish smoke. I have two concerns that I'm going to take to the dealership. One, this is just plain unacceptable from a new car (less than a year old). I'm wondering if one of the dealership personnel had this problem how it would be handled? The second is the legal implications if this plume of smoke causes an accident. Today's episode filled 4 lanes of a busy city thoroughfare with so much smoke that the cars behind me disappeared from view. I'm taking the car in on Monday and sincerely hope that I don't get blown off with "nothing we can do for you". Please let me know if anyone gets an answer that makes sense....

If you get a good answer to this issue, please post it on here. The 2 dealers I have visited blew me off with the "no error code means no problem" answer. I too have thought of the legal issues if the exhaust smoke from my car causes a wreck. I

Did anyone at the dealerships check to see where your oil level was at? I took mine in for an oil change at Nashua, N.H. hyundai 2 weeks ago and it started to blow white smoke on acceleration. It turned out they had put too much oil in the crankcase at the last change. Oil leeks into the cylinder and burns off out the tail pipe. run your finger inside the tail pipe when it's cool and see if you get a oily-greasy blackness on your finger. Good indication your burning oil!

Looks like it's time to find another place to get oil changes! A Hyundai dealer that doesn't know/care how much oil to put into one of their own cars wouldn't get any of my service business, that is for sure. Who knows what else they would mess up on?

I have the exact same problem with my wife's 2011 Elantra with 28K miles on the clock. The first time i saw the smoke was when it had about 5K on the clock, . It happened last Saturday again. Filled a 4 lane freeway up with smoke when I tried to get into the fast lane, I am going to make sure to have a video camera in the car when this happens again. I see the last post said to check the oil level. I checked the oil level after this happened and it was good. The first time it happened I accelerated at a traffic light when it turned green, I thought I blew the engine. On the way home i tried to accelerate and gear the car back and could not make happen again. Maybe the Catalytic converter gets an oil buildup and burn it when there is more flow through the exhaust? I took it to Hyundai this morning
and the guy at the service department seemed like he didn't believe me.
Does anyone have an answer yet?

Not being a mechanic...I don't think your catalytic converter is burning oil. If oil gets in there I think you have huge problems.
