Check the stereo installation.

There is a YELLOW wire that needs to be connected to a Constant +12 volts when the vehicle is OFF.

It is responsible for saving the pre-sets after the engine is off.

Best of Luck.

Memory loss

you need to remove the radio and swap the red wire for the yellow wire and vice versa, they have bullet connectors to allow you to do this, basically the permanent live and the ignition live are the wrong way round.
