I have to confess, this is for my Tundra, but I like this forum more than any other, and I assume the tech is the same. I have a 2012 Tundra with about 60K miles. I'm on the second Toyota Battery. If the truck sits with the engine off, doors open so interior lights are on, for more than 10 mins or so, the battery dies (like when you are cleaning the interior of the truck). Has also happened sitting in the truck with the key on, radio on, but again for only several minutes. Its the same thing I have done in cars all of my life and never had a problem. I had the first battery replaced under warranty because I was having similar issues and it has continued. With a multimeter, how do I insure there is nothing draining on the battery when everything is off? Does the Bluetooth on the radio "scan" and cause extra drain on the battery? Anyone else had a similar issue? I want to blame it on the Toyota battery, but we have the same in our 100 and don't have any problems with it. Thanks!
