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.

I took mine in today for blue smoke out back when passing.It doesn't do it all the time. Only 11,000 miles.They took a compression test and found one of the cyclinders is not up to par.They drained the oil and filtered it for metal and found none.They called hyundai and they said to replace the block.The block has been ordered.All under warranty.I had no problems with the dealership at all.

Joltman, I wonder if there is a way that I can use your information, maybe a case number or a job number from your Hyundai dealer that I can give to Hyundai customer services so they can look at your diagnosis and maybe get my dealership to do a compression test on my car. When I took my car in they drove it, could not see any smoke , checked the tires and bluntly refused to do a compression test. Merced Hyundai sucks!!

My tech line case#4901339.If you are not satisfied with their answer their is a procedure you can request in the manuals you got with the car.I would demand that they do a compression test.That car has the best warranty on the market and it doesn't cost them a thing to do this test.The other choice is take it to another hyundai dealership.

Did you all know that the 2011 elantra's engine crank case only takes 4.23 quarts of oil. I had trouble blowing smoke out my tail pipe and discovered that every time I went for an oil change they were putting in 5 qts which would be too much. this even happened at the hyundai dealership as well as Jiffy lube. None of them realize this. Look at your dip stick and the oil level should not be over the "F" in the grid on the stick. Mine was showing at the very top of the orange. Can't hurt to check...

Happened again couple of days ago. This will be another trip to the dealer to have them check it out. On the phone, they practically told me not to bring it in, that the issue is large amounts of ethanol in the gas. I'm taking it in anyway and having the compression test done on it. Will post back when I get the diagnosis.
