ENGINE PROBLEMS

I bought my chevrolet captiva car on 2008 from Geeyem motors, Cochin.  The cars engine was stucked in 55000 km and they replaced engine & pump after my several emails and after getting the notice from my lawyer. Even they charged rs.25000 from me.

After that the repalced second engine is stucked now in 115000km.  So the second engine run for 60000 km and now they are forcing us to pay the full amount of engine overhaul charges around 2 lakhs.  For replacing I have to 4 lakhs.

How can I change or overhaul engine in every 55000 or 60000 km for 20 lakh worth costly car? I never suggest the captiva vehicle, even getting very bad services from Geeyem motors, Cochin.  Now I do not have the car for 2 months.

How can I trust on Chevrolet vehicles ? If there is any logic for changing the engine in every 50 to 60 thousand kilometer?
