Loaner vehicles are a complimentary dealer initiative not done by the manufacturer. Those dealer's that do provide them have a limited number of vehicles and they either are issued on a first come basis or they have to be reserved..... either way when they are all gone you can still be w/o a vehicle. With that said I have had warranty work done on a vehicle for what ever reason it wasn't able to be completed in a day and I was put in a rental... not sure if that was done by dealer or manufacturer though.Did you know that Honda will not supply a loaner when you brand new $35,000.00 car is in for work unless the work is safely related? Our Subaru dealer will, when I owned a Toyota and VW they did. Hmmmmm, trade in time?
