11/25/2012 - hybrid shut down with no warning at 65mph on I-80 going West near Ohio border - thus lost power steering and propulsion. I got to shoulder safely; towed to GMC dealer - result hybrid fault code but no cause determined. Connector greased with dielectric grease, and fault could not be replicated. 12/24/2012 - hybrid failure after parked for 2 hours. Towed to GMC dealer; cascade of hybrid fault codes, and transmission harness cable replaced. No explanation given as to why harness cable failed. No component of hybrid system ever replaced. Back-up re service hx. Mailed to ODI under this tcn....updated 04-03-13 updated 06/17/2013
