As long as the servicing dealer uses genuine Suzuki parts and follows the Suzuki servicing guidelines it won’t invalidate the warranty.
I’d imagine they will given it’s a Toyota in disguise lol.
I booked in our Tucson for it’s first service and the Hyundai dealership said that they have stopped the home pick up service but make an exception for Motability customers, so they are picking it up and dropping it back free of charge.
Just showing off now cus I didn’t get that level of service 😂
