Yesterday, I was reversing to park in a parking lot and all of a sudden the steering became heavy and I couldn't rotate it. I get down and see an oil pond below the car. Realizing that it's steering oil, I open the steering oil reservoir only to find it empty. It had happened all of a sudden, I checked the approach to the parking and there was no traces of oil leakage. The time was 9.45 am and I was in T.Nagar. I called the RSA and the tow truck reached the spot @ 11.30. Loaded the car on the truck and reached the V.S.T service center on mount road. Left it for the repair work plus the 30k service. Today the SA called to inform that the service is complete and the oil drain was due to a pin on the pipe going loose. Has anyone had a similar problem. My car has run 15K, how do I make sure that this doesn't happen again?
