You can buy the geniune Toyota extended warrenty, 0 deductible up to 125K miles for around $1100. do choose the platinum option. One big plus for Toyota warranty is it is universal in USA, free rental if it needs >1 day repair, free road side assistance, and it is transferable to next buyer, so you will have a big selling point when you sell your car to a private party and get much higher price than trade in value.
I bought one for my Sienna before, used it 4 times and it well worthed the money.
