I just bought my 2019 3.5EB In January and I noticed a weird starting issue today. I went to start the truck this morning and it wouldn’t turn over. When I turned the key off and tried starting it again, it fired up right away. It was fine the rest of the day until I went to leave work and it did the same thing when I tried to remote start it. Almost sounded like there was a bit of a whiring noise like the starter wasn’t grabbing.

I checked the battery connections, and checked for any codes (none present)

Any thoughts on what might be causing this? Starter? I live 2 hours away from the nearest dealer and don’t wanna make the trip unless I have to.

Thanks in advance.

 

Likely the starter is starting to fail.

 

I also would suspect the starter, but first would inspect cables and state of charge of the battery. Your comment 'whiring noise' leads me to think the starter not engaging tho. Good luck!

 

2019.
If original battery, likely time for a new one.
My 2019 started starting a little slow once in a while. I waited a few months, was running errands a couple months ago. Started fine, went to bank, slow start from there, mile down to gas station, would not start. SIL came and jumped it, went straight to dealer (previously called) and got a replacement.
