Will I be sued if return my car?

It's unlikely that you will be sued if you return your car because it is more beneficial for the lender when cars are returned voluntarily instead of through repossession.

However, in the event that you fail to make any more payments after returning the car, the lender may take legal action through the courts and initiate a lawsuit to pursue outstanding balances and other related expenses. So while returning the car in itself should not lead to a direct lawsuit, non-payment of any remaining debts can result in legal consequences.
