Sometimes lenders report in bulk during fixed time intervals but 3rd payment without a single report raises a red flag. You should get in touch with the VW people and ask them about it. It could be a problem with the credit bureaus as well so in case VW people claim not to know anything, file a dispute with the credit bureaus. That should put things in order.
