Hyundai just rolled out the third-generation Santa Fe in 2012, so it'll be a little while yet before the crossover warrants replacement altogether. It does, however, appear to be preparing a facelifted version for introduction in the near future.
Spied undergoing testing in Europe, the updated Santa Fe looks poised to get a new grille, restyled LED foglamps, new bumpers front and rear, new taillights graphics and new exhaust tips. The cockpit looks like it's getting the once-over as well, with a new infotainment system in the dashboard.
Beyond that we couldn't really tell you at this point, but we can expect the revised Korean crossover to arrive sometime later this year. Previous generations of the Santa Fe lasted for about six years on the market, however, so we wouldn't anticipate a complete replacement until 2018 or so.
