It is not the brand of battery. This has happened 2 winters in a row in below freezing. The dealer has done diagnostics and can’t find the issue. We are on at least the third battery. The truck was totally dead and could not be jumped.

Battery is completely dead after the truck sits in cold weather for more than 48 hours. Dealer changed out battery, but it happened again. There has to be a drain on the battery some where. Possibly the seat heaters? Dealer does not want to replace the modules unless they know for sure that’s the issue.
