Self Propelled Lawn Mower will not Self Propel

I have the EGO 56-Volt Lithium-Ion Cordless Mower, Model Number LM21000SP. The SP in the model number is for "Self-Propelled". I have had this mower for about a year (two at the most) and now have an issue where the Self-Propelling system is not functioning. I press the self-propel trigger, a noise occurs under the chassis that sounds like clicking, and then the mower does not self-propel. Is there something wrong with the motor that runs the self-propel function? Is it possible that the bearings are shot and are locked up to the point that the self-propel does not work? That is what I am here to ask. Please help.
