MILES 105000 DRIVE HIGH TRAFFIC BATTERY GOES DOWN RECHARGES FULL TRAFFIC OVER ?

Hello, Are you saying that the vehicle is losing hybrid battery in traffic, or that it is losing the starter battery during traffic? The starter battery is the normal battery that would otherwise be found under the hood.

Suspect low voltage output from alternator while driving in stop and go traffic - battery charge is not sufficient at lower engine rpm .. Voltage output from alternator increasing while driving at road speed and battery charge is maintained at higher engine rpm .. Testing required: http://repairpal.com/repair-shops
