Defect

Ferrara Fire Apparatus, Inc. (Ferrara) is recalling one 2020 Igniter emergency vehicle equipped with a Weldon V-Mux Vista IV Standard Liquid Crystal Display (LCD) used for controlling emergency vehicle lighting and HVAC functions. The display may experience low voltage spikes, and cause the LCD to lock up or become nonfunctional, due to varying electrical installations.

Risk / consequence

A locked up or non-functional LCD can delay emergency efforts, which can increase the risk of injury.

Remedy

Ferrara will replace the display, free of charge. Owners may contact Ferrara's customer service at 1-225-567-7100.

Chronology of events

1. Aug 17, 2020

   On August 17, 2020, Weldon’s engineering division received a report from a customer that an individual vehicle had an VistaIV display unit installed in a vehicle that was not operating as intended and the display screen was blank. Weldon conducted a site visit to inspect the unit and began to conduct further evaluation. At the end of August 2020, Weldon was able to replicate the condition reported by the customer. Further analysis took place through mid-September and indicated that a negative electrical spike that occurred at vehicle start up contributed to the condition and Weldon had resolved the issue for the individual vehicle. It was believed that the condition was due to the replacement of a obsolete component and the details of vehicle wiring. Weldon accounted for this possibility in updating product in its inventory. In late September, the customer reported a second vehicle that experienced the same issue with the Vista IV display unit. Weldon examined the unit and in October 2020, found a different underlying issue contributed to the LCD screen on the VistaIV display unit going blank. In all cases, the screen would reset with a power cycle/restart. On October 13, 2020, Weldon decided to conduct a recall to address the units in the field. Ferrara was informed of this determined to proceed with a recall on November 30, 2020.
