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.
