So my truck is an 07 5.4 xlt. Lately my battery lift periodically will turn on and shortly after (from a minute to 10 plus) it turns off. Sometimes it will come back on but it always shuts off. I never had this problem until I got new wheels and tires put on a couple months ago. Has anyone else ever had this issue? Could it be related to the tire monitoring sensors in the wheels?

 

I would check the battery connections on the battery and alternator, corrosion will do that. How old is the battery?

 

Year and a half

 

Sounds like your alternator is going out.. do you have a multimeter ?

 

Yeah I do I'm a mechanic. I just think it's extremely odd how I never had an issue until the new tire monitors were installed. So I was curious if anyone has ever had that same issue?

 

going through it right now. My alternator was shot. But as a first step check battery / ground connections, check with a multimeter.
IDK why the TPMS would cause it though.

 

It would not...
