Followed up on your recommendation and eventually spoke with Renaldo who arranged everything in a five minute phone call. Initially Lexus Reading were telling me to use my local Lexus Dealership, but explained had already done that with three local Dealers : Lexus Derby who after two weeks were still waiting for a password to access the system!!! (there words) : Lexus Nottingham unable to confirm in writing that Roadside assistance was included : Lexus Leicester adamant that Roadside assistance had been discontinued since early 2023.
Many thanks Phil for your guidance. Maybe it is time for Lexus (Toyota) to take all the Lexus franchises in house so we all have a uniform experience
