 I purchased a 2013 Elantra new.  I immediately had issues with the mileage. It is stickered for 41 mpg highway.  I have never gotten more than 34 mpg after adjusting for the 2.7 mpg the gauge is off when compared to the odometer and actual fuel purchased.  The compensation card issued by Hyundai due to the court settlement doesn't even come close to compensating me for the lower mileage.  This is the first car I have ever had that has gotten less than the sticker.After 15k or 20k miles there were issues with the pollution control system that took 4-5 trips to the dealership to resolve.  Now at 107k (virtually all highway miles) the car engine started making rattling noises that turned out to be a bad piston.  The dealer estimates the repair cost to be over $5,600.  This is in spite of regular maintenance checks and oil changes.    Finally the two sets of 80k mile tires I have had on the car after the initial set that came with the car have each lasted less than 45k miles and developed significant road noise after about 25k miles even with regular rotation.  Never again will I purchase a Hyundai and I discourage everyone I talk to from purchasing one too.
