# Service bulletin Circular93D2REV4

## NHTSA's summary

It is possible that the high\-voltage battery housing bonded seam was made in a non\-optimal position. If this condition is present, moisture can enter the high\-voltage battery housing. The driver may be alerted to this condition by the illumination of a high\-voltage system warning indicator on the instrument cluster display. Removed claiming instructions for return and recycling, as this will be handled under the new process outlined in the 'HV Battery Recycling Program Guide' found in ServiceNet \- \> Electric/PHEV Vehicles. Updated campaign expiration date. Updated return and recycling information for HV cell modules and batteries. Updated Storage and Disposition of Batteries information.
