2020 Gladiator randomly not starting even after replacing both batteries and starter?

[Theh8er]

Oh no lol. That I have to change. Going to change that as well as the stock tail lights to LED. I was just thrilled after digging around for a week as well as multiple diagnostics that the short was found and fully resolved the starting issue. Not to mention my mechanic did the right thing money wise after having his Jeep guy come and spend a bunch of time troubleshooting. And by right thing I mean refund me money for the starter and not charge me for all the jeep technician troubleshooting.

What is by definition a short trip ? Under 50miles ? 20,30,40 ???

Depends on how often that trip is.
Those who drive 10 miles to work, shut it off, then 9 hours later drive it 10 miles back.......... or it sits 2 days at a time, not going to keep the battery up very well.

1-5 miles is what I would consider a short trip. If the engine oil doesn’t get up to 220°, that’s pretty harmful to a diesel engine. And that’s not coming from me, I’m certainly not an expert. That comes from shadowspapa, among others. On more than one occasion, he has stated that the engine oil needs to be up to 220° to be fully warmed up. Anything less than that, over time, is harmful to your engine. He has used the timeframe of 20 minutes, to be warmed up. Since I read his statement, I’ve been keeping an eye on my oil temperature. It certainly depends on the weather. In the summer, approximately 10 minutes. In the winter, 15–20. So, to answer your question, I wouldn’t necessarily use miles to depict oil temperature. Go by the temperature itself.

Can't compare to the ECODIESEL, but my gasser doesn't get up to full operating temperature even in 10 miles. You haven't burned the fuel out of the oil and so on.
Even when that coolant is up to 190, a lot of the engine isn't. When the oil is up to 220 - it takes TIME to boil out the water and fuel (at least with a gasser).

Has anyone checked the main frame ground where both batteries are grounded? After 5 years and alot of setting I would look to corrosion at this point as a cause. The ESS system must be functional and the batteries up for the remote start to kick in. Also the 2 hood switches under the hood I have had trouble with sticking and some WD-40& working them up and down took care of that as well.

This right here was great advice! And ended up being the main culprit. Meant to thank you when I first got the issue resolved. Batteries needed to be replaced and starter was acting funny. Ended up finding a ground buried that was corroded and loose. That ended up being the culprit and catalyst for everything else.

Makes plenty of sense that temps up burns up moisture in the block and get oil worked around real well. Etc..
