What size windshield wipers for 2013 hyundai sonata?

The 2013 Hyundai Sonata will make use of a 26-inch driver's side wiper blade and a 18-inch blade for the passenger's side. This vehicle does not have a rear blade. A replacement set will cost anywhere from between $20 to $60 depending on quality and where You shop. I would suggest getting something better than the generic brand ones as they will wear out quicker than most. You will likely have to change out Your blades every 1-2 years depending on the climate where You live and how often the wipers get used. It would be a smart idea to change them out before the start of the Winter season as that is the time they are likely to get their most usage.
