    Hi everyone! I'm new and just got a 2012 Tundra with 28K miles last week. Had a problem yesterday and looking to see if anyone else has had this problem. Truck had a dead battery when I bought it, I jumped it and it drove fine. First thing I did was install a good battery and new terminals because the old ones and the battery hold down bracket were totally covered with corrosion. I've had and seen a lot of cars and never seen this bad of corrosion especially on a practically new truck. Any way truck has had no issues until yesterday. My girlfriend took it to work and after going to lunch she went to leave and truck was totally dead. I had her check everything I could think of and a mechanic happened to be nearby and tried to help. Truck got towed to dealership and took them an entire day to get it running. I am going to get it tomorrow and let the asshole service guy have it. He said the terminals were the problem, didn't allow enough voltage through. This pissed me off because I've done a lot of battery and terminal swaps and never had this issue, oh and somehow the truck ran great for a week, I call bs. Just want some input or if anyone has had the same problem. Thanks.

    That sucks bro, but what's strange is it took the dealership an entire day. Was this a Toyota dealership? Never heard of terminals being problem. Yeah you want to keep them clean, but you put a new battery in. I have a 08 and just replaced the factory battery. Very interested in what you find out. Good luck

    What's the cold cranking amps on that battery, also could be your ground cable possibly or a parasitic draw in your electrical system.

    I know this is an old thread but for future reference it sounds like a broken battery post internal to the battery. (caused by excessive torque ing on the cable clamps.. This can cause intermittent problems and just show up once in a while.
