My bad luck again. It failed again in the night on same door same way. Run only for 150Km since it got fixed on last Saturday. Now at KHT Service center Whitefield. --- Double Post Merged, Feb 3, 2015, Original Post Date: Feb 3, 2015 --- This time got it fixed from KHT Fiat Whitefield,Bangalore for free of cost and they have replaced both 'Rear Side Door Lock Motor-Lock Assembly RR and Actuator RR RH' of right rear door. Taken it from there and drove for more than 20KMs and found it working as expected yet. Additionally got a call from Fiat Service and an offer for direct attention and inspection in case of repeat. Thanks Fiat!
