So this service vehicle and occasional charging system failure has been driving me crazy.I took to my dealer were I purchased car on the way down it began mis firing and shifting ruff.He pulled 6 codes u1017,c0240,u0140,u0100,u0073,u0001.When I got back home I decided to do a test I saw online for the alternator.I turned car on and turned everything on radio, wipers, high beams,hazards, acMy voltage dropped down to 11.20 and began the charging system failure alert.Than it it kicked into battery saver mode.I'm hoping that all this is being caused by a bad alternator.Is this possible??
