Why Tata is replacing my Nexon EV battery under warranty

They conducted some battery-related tests, performed two charge cycles, and then confirmed that the battery needed to be replaced.

Hi everyone, I’ve been driving my Nexon EV Max 2.0 for about 1.5 years, covering around 10,000 km. I primarily use a 3.3kW charger and have only fast-charged 3-4 times when necessary.

A couple of weeks ago, while driving with my family at 10% charge, I noticed that the battery dropped from 10% to 3% within 3-4 km as I searched for a fast charger. Given it was late at night, I fast-charged up to 25% and continued home. After that, I made a full charge of 100% and drove another 150-180 km without any issues.

Recently, I scheduled a routine service, during which they performed a software update. However, when the car was returned, the battery dropped from 21% to 3% within a few kilometres, so the service centre (SC) driver took the car back. They conducted some battery-related tests, performed two charge cycles, and then confirmed that the battery needed to be replaced.

I’m a bit confused as to what could have caused this issue. I’ve mostly charged my car to 100% unless necessary, and I usually plug it in between 15% and 30%, rarely letting it drop below 10%.

Does anyone have suggestions on what could have led to this failure, and how I can ensure the car runs smoothly in the long term?
