Hyundai Motor India — next gen i10 asta recurrent power steering failure

Purchased the vehicle in april 2013. Power steering failure major issue occurred in in august 2015. Had to replace the eps module which is quite expensive. Despite taking all care while driving the vehicle, the problem resurfaced intermittently recently and now again the eps has again completely failed. Seems there is no other option but to keep on bearing the design defect burden of hyundai as they are yet to respond to my complaint letter dtd august 2015, addressed to their top management.
