Getting some odd codes in the DTC log lately, today the brake warning light came on when I powered the car on which I think logged U1000, C1A70, C1A62 codes. I power cycled and the warning lights cleared. Measured 12.2V at the battery terminals with the car off. There is a noticeable needle drop on my analog meter (about 2V registers visually) when the car is powered on, there's also an earlier P30FE code for 12V Battery Voltage. It is the original 12V battery on my 2011. Sounds like it is finally time to replace it before any other troubleshooting? Anyone knows if Costco sells this size?
