 I bought a 2012 Sonota to replace  another. It had regular 3000 mile oil changes. I bought it to NTB for the last one in June of 2014.The sticker said to get oil changed at 58,000 He said it would be fine at 62000.No problems. I heard some  knocking  at 63000 so I had it towed in, I have a warrahty so I did not want to risk it, No oil light . No burning, No indication of oil issue, I thought it was a belt. I take i They told me it had burned through  almost 4 quarts of oil and it killed the engine. Mild weather Light driving, Reasonable oil changes a little past oil change date and this? The extended $1000 warranty won't cover it . They want $5000 to put new engine.  Beware UPDATE 4/20/2016. Hyundai did a recall on my 2012 sonota. They said the oil chamber had a coating that came loose over time and sent shards of the coating through the engine.This caused the engine to burn oil internally and the engine would lock up with no oil. Not the consumers fault. I allready replaced the engine with the cheapest one I could find at my own cost 4600.00. I also was forced to pay for the engine diagnosis 650.00  They refused warranty coverage because they said it was my fault. I only changed the oil every 4000 to 4700 miles. They couldn't see why it lost oil but they wouldn't cover it under my 2 warranties. The recall has since happened. This engine I bought is also losing oil quickly. Emptied 4 and 1/2 quarts in 3200 miles? Weird. I am taking it in tomorrow to hopefully get engine replaced with a better one and get a refund for my costs. I wish the service department and car dealership manager had treated me better through this ordeal . They tried to make me believe it was my fault. I said I took good care of my car and it was a defect. I was right. They were rude and wrong. Hoping to get a refund, a decent engine and an apology. Getting a Honda next time because of the customer service. Update. Hyundai put another engine in at my cost.5000. There is a vlass action lawsuit and a recall  in place. They do believe me know. I should get my 5000 back. Should get more for the outrageously poor service and nit living up to warranty. The engine replacement is also failing and stalling like the first. Will need to be replaced. Worst new car Ive ever bought. Customer service at luther bloomington hyundai is historically. Bad.FAST FORWARD May 2017. The hyundai engine they replaced the first with also burned oil internally and blew the engine. I bought it in for oil changes every 3000 miles. Burnsville Hyundai knew it was not my band fault as they were keeping a close eye on the car and measuring oil consumption and quality. They are going to replace the engine beacuse it blew at 100500 miles and they extended the warranty to 120000 miles because of the recall.
