2006 Saturn Vue Hybrid U0111 and P1A8D Error: Can a Worn Hybrid Battery Pack Still Support Operation?
My 2006 Saturn Vue hybrid is showing fault codes U0111 and P1A8D. The hybrid battery is estimated to be around 10 years old and appears severely degraded. I'm concerned whether the vehicle can still run reliably with a failing hybrid battery pack, or if it will drain the conventional battery and fail to start. Additionally, the hybrid energy charging gauge needle does not move at all, which suggests poor communication between the battery system and the control module. The U0111 code indicates 'lost communication with battery energy control module A', while P1A-8D points to a reference in the owner's manual. Given these symptoms, I'm wondering if the vehicle will continue to operate normally or if it requires immediate attention or replacement of the hybrid battery pack.
