This weakness in the left hand module is well known and well denied by those responsible. My 2020 F3L has had a warranty replacement on order for months with Can Am stating (in writing) that no replacement is available 'in the world'. Unbelievable!!
This solution has worked in mine: after soaking the switch block in WD40 and another brand the result was good for a short time then back to zero down shifting. Next I soaked the block with a lanolin base spray and problem fixed. No shifting problems at all now. That was 4k km ago.
I simply held a rag beneath to catch any drips, and there were many with WD40 but very little with the lanolin spray. Liberally squirt the can into every switch orifice ... lots of it. Paddle switching problem was completely gone after a few rydes through the hills with lots of gear changing. In Australia the product is called Lanox or Inox MX4.
