BMW India — BMW X5 30d, (Model year: 2016, Chassis number: WBAKS470200S5113, Engine No: 0005Y063)

In reference to our BMW X5 30d, (Model year: 2016, Chassis number: WBAKS470200S5113, Engine No: 0005Y063)I am the owner of the above vehicle and was enjoying the ownership from 2016 until a few days back and the joy was evaporated due to the inept handling of a trivial repair issue complicated by your local dealer KUN Motoren located at Mangalagiri, Guntur District, Andhra Pradesh.
The genesis of issue is :
The vehicle has been running well since we purchased the same in the year 2016 and we never experienced any problem whatsoever. That being the case, recently twice or thrice, we experienced a small jerk when using the vehicle at highway speeds of 60-80 KMPH. And, to be just cautionary I did contact our local BMW workshop and submitted my car on 3rd of January 2022 to see if there was any issue or is everything good. We were then advised that it is a minor issue and would cost us around Rs.15, 000 - 16, 000 for changing the gearbox rubber mount for which we have given necessary approval on the phone.
Later on after a two or three days' time, we received a phone call from the above BMW workshop advising that the vehicle, while performing the trail run after changing the rubber mount, had stopped midway and had to be towed to the workshop. They advised that the engine needs to be opened for finding out the defect for the breakdown while performing a test drive and sought our approval.
We then gave our approval for opening the engine for identification of the problem and for necessary rectification as we assumed that it is a minor problem. To our surprise and dismay, we have received an email from the BMW Workshop giving a quotation for the sum of Rs 25, 25, 815.24 (Twenty five lakhs twenty five thousand eight hundred and fifteen rupees) with an advice to pay 50% upfront.
Let me summarize the entire issue:
1. The vehicle has encountered a very minor issue when we were driving twice or thrice, a simple one which is hardly noticeable and has not stopped in between when I was driving.
2. We have contacted the BMW workshop and they advised us initially that just a gearbox rubber mount has to be changed and would cost us anywhere between Rs 15, 000 - 16, 000 for which we have given our consent.
3. Later on after two or three days, we received a phone call that the vehicle has been stopped while doing a test drive after the replacement part has been added. and the engine needs to be opened. We expected a minor problem and gave consent for the same.
4. But, the estimate received from the workshop for a sum of Rs 25.25 Lakhs speaks otherwise.
We are of the opinion that the entire issue is due to the inept and inexperienced handling by your workshop personnel and we are in no way responsible for the huge estimate given by your workshop, because we have handed over the vehicle in a good working condition
We, therefore, request you to take remedial steps for the restoration of the vehicle in a good running condition in which the same was handed over to the workshop.
I think BMW is a world class company with great German build and engineering. and hope necessary rectification will be done by being true to your reputation. But, if no steps are taken from your side for the rectification, I have no choice but to scrap my hard earned car and never return to purchase or dream of an other BMW ever.
