Reliability issues with my Hyundai Santro AMT

This was a relatively small issue compared to what was to come.

BhaskarGoswami recently shared this with other BHPians.

This is my first post in team-bhp. I own a Santro AMT Sportz (MY 2019), and I think that I should share my horror story with you guys.

I bought this car in March 2019. I needed a clutchless small car, and the new Santro had better AMT response compared to other cars that I had TD'd, and also that Hyundai offered much better exchange value for my old car.

Now coming to the issues. Let me go chronologically:

1. After one month itself, there was an irritatting rattling sound from the body. It was fortunately fixed by the dealership after 2-3 visits to the workshop. This was a relatively small issue compared to what was to come.

2. On entering the 2nd year of ownership, the second issue cropped up. I was taking a U-turn in a narrow street, and had to reverse a little to make the complete turn. I felt a subtle jerk at that moment. And now the car refused to go into Drive mode from R. Whatever I did, the car remained at N for a good 40 minutes. It was almost midnight and I was stranded in the middle of the road. Fortunately, it slotted into D after 40 minutes and I could drive back home. Visited Hyundai Workshop next day and they could not diagnose anything in their system diagnostic software. Told me to come back if the behaviour is repeated. ( Can you believe it??)

3. This issue occurred once more 3 months ago. This time, I was 100 kms away from home. Still, Hyundai ASS could find no solution because I could not reproduce the issue at the workshop. They kept the car for some days, drove it and finished my tank of petrol, but still nothing. I then contacted the GM of the dealership, but all sweet talk and no solution.

4. Today during my drive back from work, a new issue cropped up. The car was crawling at very slow speed in bumper to bumper evening traffic. All of a sudden, the car went DEAD. Literally. The engine was off, headlights went off, ICE was off, and the car did not respond to any ignition input from the key. It behaved as if there was no battery in the car. After about 3 minutes, the car came back to life. The lights turned on, speedometer console turned on, and the car responded to ignition. I drove off from the traffic and inspected the battery connections. All well and good. To me, it felt like the car software restarted in the middle of the road.

After today's incident, I am really worried. Since I have only one car, I have to even take it on long distance trips, and that too with family. I have no faith now in Hyundai ASS people and seriously doubt that they will be able to find a solution tomorrow.

If anyone in the community has some suggestions, please help.
