Service bulletin A18-114

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.

ATS170301	2017-06-30. Service bulletin. "TECHLINE SUMMARY ARTICLE - DO YOU HAVE A VEHICLE IN FOR A WEAK OR DEAD BATTERY, YET THE VEHICLE AND BATTERY CHECK OUT OK? FROM OUR INVESTIGATION, WE’VE FOUND THAT A SOFTWARE BUG IN THE VSA SYSTEM MAY BE KEEPING IT AWAKE WHEN THE IGNITION IS TURNED TO OFF. THIS CAN CAUSE A 350 MA PARASITIC DRAW THAT MAY RESULT IN A WEAK OR DEAD BATTERY. WE’VE ALSO FOUND THAT THIS ISSUE APPEARS TO HAPPEN ONLY WHEN A CERTAIN SHUT DOWN PROCEDURE IS DONE, AND IT’S RARE WHEN IT DOES."
ATS170207	2017-06-28. Service bulletin. THE APP INSTALLER ICON, LISTED UNDER APP LIST ON THE DISPLAY AUDIO SCREEN, HAS DRAWN A FEW QUESTIONS FROM CURIOUS CUSTOMERS. THIS ICON IS MEANT FOR FUTURE APPS THAT MAY BE DEVELOPED. AT THIS TIME, HOWEVER, THERE ARE NONE AVAILABLE OR ANY PLANS TO DEVELOP THEM

ATS161223	2017-05-11. Service bulletin. "TECHLINE SUMMARY ARTICLE - NORMALLY, ANY TIME YOU DISCONNECT, JUMP, OR REPLACE THE BATTERY, DTC C0051-54 (STEERING ANGLE NEUTRAL POSITION LEARNING INCOMPLETE) WILL SET. THIS DTC CLEARS ON ITS OWN WHEN THE VEHICLE IS DRIVEN A SHORT DISTANCE. YOU CAN ALSO CLEAR IT BY DOING THE VSA SENSOR NEUTRAL POSITION MEMORIZATION WITH THE I-HDS. BUT DUE TO A SOFTWARE BUG, NOW, WHENEVER THE BATTERY IS DISCONNECTED, JUMPED, OR REPLACED, TWO DTCS ALSO SET AND WON’T GO AWAY ON THEIR OWN."
