joeb Posted September 8, 2014 Report Share Posted September 8, 2014 Try a new shop. Or dealer. Can u get a refund on battery or alternator? I think ur mechanic owes you an explanation. Unless its a family member. Link to comment Share on other sites More sharing options...

MAC Posted September 10, 2014 Report Share Posted September 10, 2014 Promblems could be: 1. Bad battery ground; 2. During repairs, connections to alternator and/or battery not properly secured; 3. Battery or ignition fuse(s) blown (use Owner's Manual in glove box to determine where fuses are and check); 4. Positive/negative battery connection(s); 5. Starter; 6. Security system problem. Best chance of determining what's going on is to see if there is a trouble code(s). Link to comment Share on other sites More sharing options...
Cadillac Jim Posted September 16, 2014 Report Share Posted September 16, 2014 I would start with running the OBD codes, paying special attention to those starting with P or thrown by the PCM that are CURRENT. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
