It's an installment loan - and no, it does not hurt. I have 2 installments - a lease and mortgage. As the lease is paid down, your score will go up.
If the car lease is your only installment, when the balance reached zero, it will hurt you. When you add another installment, you'll see a bump. Toyota likes to report a lease balance of zero 30-60 days before it actually happens.
