Chronology :
Refer to NHTSA Recall 23E-084 for Weldon’s chronology.
In early October 2023, Weldon was notified that external wiring in a vehicle using the node had melted. The part was returned to Weldon for analysis in mid-October where it was found that when an external short circuit occurred, the electrical output did not shut down as specified. Weldon conducted testing and analysis of the version of the node used in the vehicle as well as prior versions of the node and it was found that for the version of the node installed in the vehicle, the electrical current sensing calibration was outside the specified limits. Weldon found that the calibration was previously updated in production, but was not considered to pose a broader concern at the time. On October 24, 2023, Weldon decided to conduct a safety recall to address the issue.
On November 15, 2023 – Ferrara received information from Weldon regarding recall number 23E-084.
Engineering reviewed potential population and inventory reviewed.
November 27, 2023 – Ferrara determined the final population. The issue was escalated to REV Group Management.
November 29, 2023 – REV’s senior leadership approved a voluntary recall for this issue.
