2004 Titan 193000 miles....
Truck can sit for a few days and then starts easily. Other times it's dead the next day, no power at all. I can hook up jumper cables and then it cranks over.
This is getting hard to live with!! So far the dealer ship has replaced the body control module,,,seat motor passenger side,,,alternator,,,battery.... Dealer also replaced rear axle seals and I added upgraded venting system
Could the ECM be going bad?? I spend time at our hunting lease,many times by myself and I don't want a dead truck in the middle of nowhere!!
Any suggestions

Check for bad grounds.

I may have found the problem---Battery fuse on positive post--the plastic cover on the top fuse is totally gone and fuse wire is exposed to the elements and looking rough. Just ordered another unit and will find out if this is the problem..

I'm glad you found your issue, but your dealer is throwing stuff on the wall to see what might stick.....all on your dollar...and it looks like they're ripping you off with incompetence. No excuse...that open fuse issue is something they should have seen in initial inspection...no tools needed....just observation skills and at the very least while replacing the battery. Otherwise....everything you mentioned they replaced has a diagnostic that tells whether the part is in spec...or not.

Did they even start with a single diagnostic step....like put a multimeter with an amp arm on the battery pos wire to see what the draw down was with the key off? That tells you if you have an electrical problem based on a short. In spec...no short drawdown?, then there's a decision tree to follow for diagnosing the general system problem area for faults and drill down from there.

Something to consider.....anytime you get the call that they want to replace something....approve the job with a condition...if it doesn't solve the issue you brought the truck in for, then there's no charge. There are shops that will take that challenge because they actually diagnose problems before committing to solutions. They call it 'first and final'.

I'll know by Wednesday when my part comes in and I replace it....Battery showing 3.7 volts this morning!!!
