Yes and there was a LR tech advisory on this a few years back - where the A pillar plastic cover clips on water runs down and into the A pillar then into the foot wells. I had this issue a few years back - was only the passenger side in my case.
I took the A pillar cover off, and put gaffer tape over all the holes in the pillar. Where the protrusions on the inside of the cover clips into the pillar I covered this area with silastic then put the cover back on - the sealant seals around the holes when it dries.
No had a water issue since.
Oh - certainly WindScreen Obriens know of this and when they replace the windscreen when they reinsert the pillar covers using new clips they also used sealant where the cover clips onto the pillar.
