## NHTSA's summary

Altec has learned that a 12\-volt Airtronics relay installed in the PDM could have been manufactured to an insufficient threshold on certain units built from December 2004 to October 2022. This can cause the relay to overheat and fail, causing the accessory lights to stop working.
