Very expensive maintenance

The car is a great drive. The following are the drawbacks (a) Very expensive on maintenance. On my 60000Km service I paid Rs 21000/- for servicing and was told by Renault Mayapuri that additional work was required on my car amounting to another Rs 40000/- approx despite my car being under extended warranty at the time of servicing. Some problem with the clutch which was repaired by company about two years back under warranty, the same again required to be replaced. This aspect reported but not satisfied at all by their reply. (b) Being top end model when purchased the music system provided does not have remote. The music system too went faulty and replaced under warranty after month and a half. Hope the Company resolves my problem.
