my ocd I had to check mine. 22 Overland and look at the bend on this wire ? Looks like they have changed the routing on these a few times ? Not impressed . If you look close you can see shielding on wire, crinkled a little. Add some heat too that ?

What’s work?
It’s worth investigating with there being cases. I’ll approach it from technician standpoint. Usual pin to pin, pin to chassis, ohm across motor terminal pins and unswitched battery terminal to case. Obviously it is an issue with unswitched battery supply or internal ground fault on motor. But I’m not running out for an anxiety med prescription yet or laying on a couch telling some dink about my child hood over it. There about 1000 different variables. Variables that might not affect other vehicles. Maybe there is clamp in the wrong spot, maybe harness is in the wrong spot, maybe bad crimp on receptacle or pin, just a few. Doesn’t include all the external influences, like did homie with 1700 miles or whatever it was think it was a Russian sub? Somebody doing something crazy with steering? Earlier this year was teaching my wife how to back a trailer, by the time we called it quits that pump sounded about dead, I drove it home and backed into yard and steering power had faded horribly. It’s good a case is open and if there is an issue a campaign will soon follow. Park it outside or over at your in-laws house in their garage maybe, but I wouldn’t overdose on Tums just yet.

I’ve seen worse bends in same size and bigger cables that were exposed to far more environmental and vibration extremes than anything these Jeeps will ever see. Insulation will in most cases develop a memory and stretch. What I don’t like about that is the “loop” on cable directly behind connector shell, bends like that can cause stress and spread receptacles inside shell. In my trade we refer to that as “spread pins” which cause all sorts of issues on both small and large wiring.

Yes, I have also seen that and fretting of the pins also. From vibration and corrosion.

Yeah and that’s been making me wonder some on that considering the motors location. Possibly water migrating past sill seal or face seals.

That loop in that picture would be a prime candidate for sill seal issue.

I think I’m going to park it at my brother in laws garage and hope for the best. I have oodles of positive equity in it so I’ll get a check but more importantly he’s and asshole so win win

Good time to check those smoke detectors in the garage, while we are on the subject. Memory fails me but I think they exp. around 5-7 years.

either my wife’s cooking is getting better or mine are due, haven’t heard em in a while.

Could do like we do for dirt bikes and open the plug and put some silicon grease on the rubber sealing edges to help reduce water migration. Don't coat the electrical contacts in grease that only reduces connection quality and could cause resistance/heat.

I store a 2021 Gladiator and 2023 Wrangler in my garage for a week straight sometimes since we don’t drive them much. Yikes. Right under our bedroom.

Absolutely, I do that a lot anyway just at work, usually the dirt and mud interfere with the interface so it helps. Also depending on the seal some deform and limit interface anyway just from the friction. We shall see, few days before I go back to work so I’m diving in to investigate the entire circuit and motor.

My concern too! I have a commuter car that moved outside when I got the Jeep and it didn't take but 2-3 months for a mouse to move in (along with all his personal linens lol), to my cabin air filter!!! After he died, I realized he was there and got that mess sorted. Then it took about another two months till a new guest was there. I've recently waged war on the vermin around my house, got about a dozen bait stations around my property now.
Forget the bait stations, use the bucket trap method.

Dived in, pulled air box and intake tubing. This is what I found in the first few initial pics of the pump and control wiring in the wild. Few things of concern for me anyway, may not pose a design or operational concern and likely don’t but worth mentioning as follows: location of pump, not only is it absolutely exposed to road spray, car washes, etc but so are starters and in reality or at least hopefully is sealed better than a starter so that likely is moot but…who knows. So more than moisture is heat saturation. Zero air flow from either air flow across front of truck or from fan. Some air likely off fan as shroud is open on both sides, problem is that would be hot air with now where to go. Lack of air isn’t the issue as much as it has no where to go, pump unit is blocked on three sides.
Un-switched battery: mine as the earlier poster had the preload in power in with loop. Once I removed the connectors and looming receptacles are fine with no signs of spread, copper core passed pull test, and connector is clean and dry compared to shell exterior. Nothing really alarming honestly, if it’s thing I guess it’s a thing. I’d say pump related more than anything or some random build executions during assembly.

The one thing I noticed is that my 23 and 24 have a smoother transition into the curve of the wiring compared to your photo and one other photo a member posted? Maybe it means nothing but I will mention it for discussion.

Cleaned connectors, applied dielectric grease to interior edge of connector module on pump unit. Removed this small section of the builders loom and tape as that is the cause hard bend. Enough at least on this truck to pull up 1 to 1.5 inches and secure. Takes the bed out and receptacle preload off.

i did a quick look at my EcoD pump, and it looks like the only thing separating the pump and the wheel is the finder liner, with about a 3" gap that exposes the mounting bolts for the pump, I would assume that gap will give the pump a little breathing room. I would like to take my IR gun and zap the pump after doing a little driving to see how hot the motor casing gets.
