Just had my CP4 replaced per the recall and the day after the dealer did the work I couldn't start my truck without a jump. Something's drawing on the batteries when the truck is off. Having to bring the truck in to see what's going on but I can't get the truck started anymore without a jump. The dealer said "it's possible it's related to the fuel pump work." Anyone experience this? I fear I have two bad batteries now because they're not holding a voltage of more than 12.2v. When I hit the start button, I hear one click. All other electrical systems like the radio, dash information, etc., are good. Very frustrating.
Also, they did a flash with something about "insufficient engine warmup protection," I have no idea what that is. The weird thing is the invoice says ECM Aisin Transmission when I have the 68RFE.
