First month extra bolt stuck near the rear brake pads and caused an issue while applying breaks. In the sixth month the car center lock system was not working, can't lock the car and it was there in the showroom for 1 week. After one year of AC compressor issue, they replaced it. Now battery pack issue and it has been there in the showroom for nearly a month. Don't know when it come back from the showroom. Tata Motors released this car to do R&D on passengers.
