In March 2021 capacity was 20,000 trucks, 2,500 and 3,500. In October, a second recall included 130,000 trucks, with an additional 280,000 Cummins-powered trucks the following month.

All of this is a ram memory that pales in comparison to December’s more than 1.4 million Trucks. This involved the tailgates not closing properly from the misaligned latches. The concern was that when the tailgates were opened quickly, cargo could leak out which would cause hazards to vehicles coming upon the cargo en route. Trucks from 2019 to 2022 are part of this recall.
