It would be more effective if you call to bank to ask. They sure have contact that handling loans in their website.

I saw there is big problem in ur case which that u bought car with cash and u didnt declare ur income tax. If LHDN noticed that u bought car with cash and did not even declare ur income tax, they will started to investigate on u. U better start to declare ur income tax and get some advise if u don't know where to start. Do filing on ur income statement for the last 7 years is the wise move.

Good luck.
