Starting to sound like they aren't jumper cable friendly either! Reading up on abs/esp failure I have to wonder if my whitetop might not be the issue.. per the manual if it doesn't see 12v it has fits..(okay not exactly per manual).. just wonder if 11.8 volts would crank and "act" just fine from the drivers seat. Was thinking hook up the tahoe to jumper cables for testing before replacing the battery but now???
