 I loved my 2002 Elantra.  I needed a larger vehicle so I bought a brand new 2013 Sonata.  My Sonata started burning oil around 36,500 miles.  I have been going back a fourth to the dealership doing oil consumption tests.  After 3 tests, it has burned up 4.5 quarts in about 2,000 miles.  I still can't get anyone to fix the problem.  Instead, the dealership says I need to do 1,000 more miles of oil consumption tests and corporate says I need to do 3,000 more miles of oil consumption tests.  The warranty sounds great but good luck with getting them to fix anything that is covered.
