My car was under service in V3 Hyundai for LPG blockage issue from 29th March 2017 Onwards.
Service Advisor name : Sathish ([protected])

First two days he analyzed my car and he come up with a proposed solution for the issue on 31st March 2017. He suggested to change “Air Mixture”.
But the item is recently changed for the same issue. The cost will be around 9000 Rs. For the same issue I changed this during last time service (Nov 2016), So I said the particular item is already changed recently, So I Asked him to check for the warranty.

After that whenever I asked for the Car Service Status, He said that, “We are working on it, You will get delivered by tomorrow”. The same status I will get each and every time.

After a Two weeks later, He found a new solution for the same issue. He suggest to change the “Switch controller”. It will cost around 17K.

How many solutions your team will have for the same issue. The entire Kit will be less than the proposed solutions.
If your mechanics are not able to find the exact solution for the issue, Then really they are trained?

If Switch controller is the exact solution for the problem then, Why they changed the Air mixture last time & This time also your mechanics are suggested the same solutions for the same initially. Since the “Mechanical Part” is recently changed and it is under warranty, They found a new defective item.

So now suggesting to change the new item which is not in warranty will cost around 17k. If this is the real defective item, then why I paid around 9k for Air Mixture Change.

Either the mechanics working in V3 Hyundai doesn’t have enough training to identify & fix the issues, Or they are trying to achieve their monthly target amount.
My assumptions, Irrespective of the issues and the corresponding fixes, They are working for their monthly targets, So they are suggesting the customers to change the items, Which is really not required to change to achieve their targets or Their experts not enough trained to find the issues and solutions.

During Nov 2016, V3 Hyundai charged around Rs. 1, 45, 000 for the accident service
Dec 2106, Rs. 16K for general service
I am not sure how much I have to pay for this time.

Please check about this issues and let me know the solutions for this.
