# Service bulletin LTB00572NAS1

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

"SITUATION: THE HEATED FRONT WINDSHIELD MAY NOT OPERATE AND EVIDENCE OF HEAT DAMAGE MAY BE FOUND IN THE ENGINE JUNCTION BOX \(EJB\) / UNDERHOOD FUSE BOX. DIAGNOSIS MAY DETERMINE THAT THERE MAY BE SIGNS OF VISIBLE HEAT DAMAGE TO EITHER THE HEATED FRONT WINDSHIELD FUSES, HEATED FRONT WINDSHIELD RELAY, OR THE EJB / UNDERHOOD FUSE BOX. CAUSE: AT AMBIENT TEMPERATURES APPROXIMATELY BELOW 38F/4C, THE HEATED FRONT WINDSHIELD AND HEATED REAR WINDOW WILL TURN ON AUTOMATICALLY. THIS MEANS THE HEATED FRONT WINDSHIELD AND HEATED REAR WINDOW MAY BE ON FOR LONGER PERIODS OF TIME WITHOUT THE DRIVER KNOWING. THE EXTENDED OPERATION CAN RESULT IN OVERHEATING OF THE FUSES WITHIN THE ENGINE JUNCTION BOX \(EJB\) / UNDERHOOD FUSE BOX."
