I have heard this as well from the dealership. Also heard that you would have to replace the entire piece around the grille and not just the bar with the Toyota logo. I'd like to know if the pieces provided would fit the 2020 as well.
That is completely false, but the dealership may have their own policy to not special order parts without VIN fitment verification. If your dealership won’t order it then go to another one, or order online. I posted links a few pages back to the two parts you need to order, with discounted online prices. You only need the two parts that bojack72 referenced. It will say it’s on backorder. Go ahead and place your order. Mine arrived within a couple weeks.
