 I got my Elantra just a little over 5 years ago and its still going.  I purchased the extended 100,000mi/10yr bumper to bumper warranty.  Ive had to have my air bag sensors (both driver and passenger)and Kenwood CD player replaced. Ive also replaced my headlights a few times.  Didnt have to pay for any of it!  I leave my headlights on ALL the time so burning them out is to be expected.    Over all Im am super happy with my Elantra.  I drive between 20 and 30 miles every day on average and get great mileage.  Maintenance is a little pricey (in for my 60k,today ouch!) but the dealership is reliable and friendly (same guys in the service department since I got my car!)
