It's the inconsistencies that frustrates. Missed journeys, car showing as unlocked when in fact it is locked and vice versa , car being shown as parked miles from where it is actually situated, mileage incorrect and number of days countdown to service incorrect, mileage sometimes shown as km etc etc. Some days its perfect but on others it's not. You just have to look in the NX forum to learn of the issues with the app!
Twenty-one months on and the system is improving but in my opinion its still not robust and worthy of the Lexus brand.
