Battery explosion and fire in Honda WRV

I have WRV model 2018. On 16th June, 2021 my car battery exploded in my garage at midnight without using my car. My fathers fingers were burnt while controlling fire. I informed Honda service care regarding the same and after reviewing they blamed short circuit instead of finding the root cause. I have already informed them that no one was using car and car was parked but they didn't believe me and assumed everything without giving me any explanation. This was a common issue in Honda cars and due to this they had to recall 21 lakh cars back in 2017. Please google this and you will get complete information but now they are denying everything and not giving any solution to me. I am really frightened as lives were at risk due to explosion and this can reoccur in future if they didn't find the root cause. I don't know what to do with my car and I will not feel safe in car again. Please don't buy this car.
