How to add a new array in the structure?

Let say I have this structure ( vehicle.genset_model) where inside this structure I have vehicle.genset_model.drag=[4;5;6;7;8;9;10]. This file is saved as mat file. In this file I want to create a new array that should be in the same structure (vehicle.genset_model) but with the extension temperature i.e., vehicle.genset_model.Temperature=[25;28;31;34;37;40;43]

clc, clear

vehicle.genset_model.drag = [4; 5; 6; 7; 8; 9; 10];

% save structure array in 'data.mat'
save('data.mat', 'vehicle');

clear

% load data.mat
load('data.mat');

% add a new field
vehicle.genset_model.Temperature = [25; 28; 31; 34; 37; 40; 43];

% save new structure array
save('data.mat', 'vehicle');

clear

When I do this I get this error Unrecognized property 'Temperature' for class 'genset'.

On which line, you get this error? The code is pretty simple and it works.
