Service bulletin A15-057

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

"SERVICE BULLETIN - THE CELL VOLTAGE SENSOR MAY INCORRECTLY INTERPRET ELECTRICAL NOISE FROM THE INVERTER AND MOTOR CIRCUITS AS A PROBLEM AND CAUSE THE VEHICLE TO SWITCH TO A FAIL-SAFE EV MODE. ADDITIONALLY, DTCS P0B3B, HIGH VOLTAGE BATTERY CELL VOLTAGE SENSOR INTERNAL CIRCUIT MALFUNCTION AND P0DA8, MOTOR POWER INVERTER MODULE VOLTAGE MALFUNCTION ARE OFTEN STORED. IF THE VEHICLE SWITCHES TO FAIL-SAFE EV MODE WHILE CRUISING AT HIGHWAY SPEED, THE ENGINE SHUTS OFF AND THE VEHICLE WILL EXPERIENCE A SUDDEN LOSS OF POWER AS THE FAIL-SAFE EV MODE LIMITS VEHICLE SPEED TO A MAXIMUM OF ABOUT 40 MPH. IF THIS OCCURS, THE VEHICLE MAY BE ABLE TO TRAVEL FOR UP TO 2 MILES IN FAIL-SAFE EV MODE, AT WHICH TIME THE HV BATTERY WILL LIKELY FULLY DISCHARGE. IF THE BATTERY COMPLETELY DISCHARGES WHILE THE VEHICLE IS STILL IN OPERATION, THE VEHICLE WILL STALL, INCREASING THE RISK OF A CRASH."
