I live in Texas and a friend of mine had one of these. The retest would sound as he was driving but wouldn’t allow the test to be done until the car came to its next complete stop.

The plant had been shut down for quite some time as the current situation in Venezuela had made it next to impossible to acquire the needed materials to make cars. The govt made GM to pay the employees even though they were not actually working, so rumor is that GM sis quite happy with this seizure.
