The 2018 model of the Toyota Highlander will need to use a 26 inch driver's side blade, a 20 inch passenger blade, and a 12 inch blade in the rear of the vehicle. If You're going to purchase a full new set for Your vehicle You need to double check that it includes the rear blade as not all of them will. A full set of 3 will cost between $25 and $50. I suggest going with a premium brand as they last longer so You want have to hassle with a replacement any time soon. In general You should be changing out the blades every 18 to 36 months.
