I've recently been seeing some posts on SVTP about some Coyote owners having an issue with batteries draining. Kinda weird how they all happen around the same time frame. Thankfully I haven't had any issues to date. I only started my car once during the icy days and it started right up with no issue.

vast temp variation is my guess.
Last month we've had quite a few 50 degree up and down drops in temperature.
Combine with those that park outside and drive everyday..rain sleet or shine.

Part of the battery issue is probably because so many people believe that modern car batteries are 'maintenance free' like some are advertised. Truth is, if the cells can be accessed by a cap then you have to check the water level and add distilled water before the plates are exposed to air. Otherwise you will certainly have shorter battery life.
