Jamesok1, it seems we r having similar issues. I had a left rear indicator failure for about 2 weeks. The top bulb signal light was not working. Other than that everything worked as it should.
I finally decided to change the bulb today & when i was done, the damn thing wouldn't start. It read "Low battery start vehicle", "Service Stabilitrac." After being pissed of a few minutes, i jumped it and it started right up. It had the anti theft indicator on so i turned it off, locked it, tried remote starting it & worked. Left it on for the 10 minute cycle. Then off until later on in the day.
Fast forward to 10pm when i was about to take my daughter to see the firework show, NO START!!! SMH
I jumped it again, this time with my Whistler Jump Starter. Starts right up! I left her running for 2 hours before shutting her off & going inside. We'll see what happens tomorrow morning.
After reading this thread i just hope its a bad battery! Somehow i don't think that's the case with me because when i connected the jumper cables to the trucks battery and then touched the others together to see if there was any charge, there was plenty of spark. Hopefully Im wrong!
It all started with a damn signal light bulb!!
My truck is also a 2014 with 52k
