Some 2013 model year ES 350 and ES 300h vehicles may exhibit a condition where the passenger headlight and rear defogger operate continuously. This condition may be caused by a poor ground for the Engine Room Junction Block Assembly on the left fender side panel bracket after a collision repair. This may occur during body shop repairs or other repairs where the left side fender bracket grounds were left loose, not properly attached using correct bolts, or improperly painted, and the vehicle?s battery was connected.
