Ford Focus (2011) 1.6 petrol - o/s driveshaft oil seal leaking - Peregrine

Is anyone aware of problems with the o/s driveshaft oil seal on the new Focus? My car is a 2011 Focus 1.6 Zetec. A year ago at it's first annual service (at 8.5K) the dealer reported that the o/s driveshaft oil seal was leaking and replaced it under warranty. Last week at the second annual service (at 12.5K) the same fault was apparent, it is being replaced again under warranty. I had intended to hang on to this car for a few years, but I'm beginning to wonder!

The dealer should be looking for some other causal factor beyond a simple defective seal. Imperfections in the drive shaft surface for example. Excess movement of the driveshaft.
