2022 6.4L Starter issue

[gregmerz]

I own a '22 Ram2500 with the 6.4L which has been perfect with one issue. Once each year, like clockwork and within weeks of the one year mark, the starter fails. If I replace the starter, all is good. Just put the 4th starter in the truck counting the one it came with. The truck is still under the extended warranty but the local Ram dealer service departments are so backed up I usually get offered an appt about two weeks out and I have to get to work each day so I end up paying for the repair myself.

I've read about the conductivity issue with the nut holding the power cable on and the heat issue due to the proximity to the exhaust pipes. Anybody had this issue and found a solution ?

I hate to sell an otherwise dependable truck but this annual failure is real irritating and it always happens in the dead of winter.

How are you testing the starter when it fails? Test light should light strong at the solenoid lead when cranking. Should light all the time at the main lug. I'd also disconnect/clean/reconnect the battery terminals then check for a voltage drop between the main lug and the positive battery lead with a multimeter.

What brand starter are you using?

I have not tested the starter when it fails. Before replacing I checked connections at battery block and starter for corrosion or loose fasteners. Absent problems there I just replace the starter, gotta get to work. Two have been replaced with "remans" the one about 10 days ago was OEM new. I need to keep the old starter next time it fails, disassemble and test the starter to see where it fails.

Repeated failures like that scream for additional diag - though the fact that you used an OEM one this time is a good thing. Many aftermarket remans are not up to snuff. OEM supplier companies like Denso can be an exception but you typically pay a premium for them.

Glad its working for now.
