Tata Motors — Car is not starting

Address:

Katghar Moradabad 244001

2 times I faced this issue
1st time I was in Tata motors authorised workshops for normal health check and washing of my car, but after car wash when the car was given to me it is not starting at all and all the instrumentals light are on.
All the workshop buddies tries to solve this issue but no one was able to solve that, then i have to spend whole day in the workshop but the car is not fixed, i have to drop the car at the workshop and next day whole day was spent on my car, in the evening suddenly the car is working normal, even the workshop engineer have no idea about the fix, but that time it was fixed i asked them if this problem occur again and if i was on my way and it breakdown then how i will manage, they assured it won't happen again.

but again today 26/aug/2022 i was driving and suddenly the same thing happen again and i am not able to start the car and all the DRL instrumental lights are ON, car is not able to start/locked i was on the road side not sure how to fix this, already call to workshop manager for help but not getting any solid answer from their end.

I need to raise this concern to senior Engineers of Tata motors so that they can help on that because nobody knows here what is breakdown and how to fix that.
