If you find a clause about reinstatement, that’s great news! To reinstate your car loan, you have to repay all of the monthly payments you missed, as well as the repo fees and any other fees the lender charges. This must be in a lump sum.
You typically have about 15 days to reinstate your car loan before the vehicle goes to auction, so act quickly!
Best of luck, and hopefully your financial straits improve soon!
