I have tried just about everything to keep my power steering pump from overheating. I'm on my 3rd power steering pump at 8,000 miles. I've cut the inner fender well out to provide more air. Installed the Apex power steering cooler and nothing seems to help. If you use your Tazer to run your radiator fan non stop if will certainly help. The loud noise of the radiator fan on high gets a little old after awhile. Last week I installed an electric fan directly in front of the power steering pump and it seems to have fixed the problem. I spent the week in Ouray, CO, aired down to 12 psi on 37x12.50 tires and never got the power steering hot light. I need to build a better bracket for the electric fan but I believe this is the fix for the power steering hot light.

Mines a ‘22 and the power steering hot warning has come on twice now. Once this summer @ 9k on the highway on a hot day but I don’t think the steering was actually hot. Came on again this morning about two minutes after a cold start so I know it isn’t actually hot. Has anyone located the ground location to check if it’s possibly loose? Thanks
Good information thank you. I also have the Apex kit but every single offroad trip the steering overheats once you get into tough spots and have to spend time back and forth to make an obstacle. Typical trail drives are no problem.
I am leaning towards the full psc kit.

Do you know the location of the ground wire. I'm having the same issue. Mine is only 3 months old.
Thanks,

Mines currently in the shop with the same issue. The second time there with the power steering hot issue, with the power steering going out on me like 5 times. They keep telling me they can't replicate the error so there's nothing they can do. I provided them screenshots of the error and even a live video of the issue. They still tell me unless one of their certified mechanics can replicate the issue, they can't start figure out what things to check. its blowing my mind, got in heated discussion with the manager at one point. I was like, i'm providing you with the error message and a video of the issue, whats the different. Its the power steering going out when i'm on the highway and high rates of speed at times...and what you are telling me is that you need your mechanic to get out on the highway and have the power steering go out. Don't you realize if that actually happens there is a chance they could cause and accident and kill themselves or someone else. dude, was like, well you can still steer...i was like, i have 37" tires...its actually hard as fuck to steer the jeep, have you ever tried. He goes no. It just doesn't make sense, i'm not talkin about a radio error, i'm telling you and showing you the power steering goes out. I have a 90,000 dollar jeep 392 and i'm afraid to drive on the highway because i'm afraid the the PS will go out and you are telling me you don't know what avenues to go down unless ur mechanic can replicate the issue. The error message should point you down the avenues to check. Plus you are certified jeep dealership with certified jeep mechanics, you don't just know what to check when someone says "my power steering is going out". Its the wildest thing i've ever dealt with. I even said, i can't even have my wife or kids drive the jeep because its an accident waiting to happen and dude goes "well not having them drive your jeep could be a good thing". Unreal. Been there for 5 days so far, no status...i guess i just wait til next week and see what they say again. Just don't understand what them seeing the error message vs me seeing it and reporting it matters.
It’s posts like the above that get me thinking “Why did I pay money for an extended warranty?” I hope that the day I bought the Jeep is going to be the only day I ever visit a dealership.
Sorry to hear you’re having deal with that alongside issues with your ride. Tell them to check the grounding.

Has anybody posted about ground location on the non 392 Jlu Jeep forum and got a response? I am not on that forum. Or anyone who has pulled their pump out to up grade it with fender liner off should be able to chime in on this. Thanks

I’m having the same power steering hot warning issues on my ‘22. Started intermittently around 7,000 miles. Only happed about three times since then and now just about to 15,000 it just started coming on about every time I drive it along with the battery light coming on and the voltage jumps to 15+ volts. Any idea on the location of the ground? I hate to take this thing into the dealer for anything. Thanks!

The attached schematics are for the 2018 model but pretty much anything I've dug into on my 392 matches including the three ground lugs behind the right headlight. The large lug among the three appears to be G908A which is the electro-hydraulic power steering ground.

I had a 2019 Rubicon that came with their gen-1 aluminum steering box. Within the first year, Jeep replaced it with their steel steering box and that darn box was awesome. I never received a steering hot warning and I could actually steer the Jeep, on 37’s, with my lockers engaged!
Fast forward, May, 2021, new 392. I’m running the same wheel/tire combination, which came off my old 2019, and I start getting the steering hot warning… even on easy trails! In addition, I could barely steer the jeep when I turned on my front lockers!!! So I take it back to Jeep, bla-bla-bla, nothing fixed and they can’t replicate the issue…. To make matters worse, there were not any aftermarket options!!!
My advice to everyone is to call Jeep Cares, open a ticket/case with them, and have them work with your dealership to investigate the issue… this will at least give their mechanic access to one of the Jeep engineers so they can investigate it further. Heck, someone said that they put 3 steering boxes in there and still haven’t fixed the issue… I think it’s time for that shop to try something different!
IMHO, Jeep’s steering box cannot handle the weight of the 392 engine and a larger tire without some upgrades. This isn’t a direct knock on Jeep because I think that the majority of the makes/models out there couldn’t handle a 500 lbs motor weight-gain as well as jump 2x to 3x in tire weight without upgrading a few steering components.
Should Jeep have upgraded the steering for the 392… sure, and I think this was a big oversight for a $90k+ vehicle because the non-392 Rubicon models can handle 37” & 38” tires with the factory box… so it’s silly that many of us cannot do the same thing… but better and with more power
.
Unfortunately, the 392 is not about selling units… it ‘s about selling the biggest unit out there and one-upping the Ford Bronco. Mission accomplished.
392 owners may just have to “Pay to Play”… but we have it easy now. Just ask any JK owner what they have to do to their jeeps before they can run a 37” tire

Thanks Leftfield I think that’s exactly what we’re looking for! I’ll check that ground and update with the results. Good work!

I get that they can’t do much about aftermarket steering components or the drivability of aftermarket lifts and such but this power steering hot warning is an electrical issue and has nothing to do with the actual mechanical components.
So when i got there, i asked if they had any idea what aftermarket items they thought might be the issue and the seemed to push towards the electrical mods, which are only the addition of Oracle Rear Taillights and Cube Lights I had installed in my aftermarket Bumper. I can't imagine the taillights would cause this issue but i guess there is a possibility that the shop that installed the Cube lights in the bumper did something. Who really knows. I guess i remove them and go from there. Its just disheartening overall that they seemed to not care that i'm talking about a major problem that could have life and death possibilities especially on a highway at 70mph or more. And from the beginning they never mentioned anything about my mods until after they said they couldn't replicate the error messages. It wasn't like i showed them the message, they asked about mods, and then said go kick rocks...we can't do anything for u because you added different taillights. Its like they used that as an excuse for not knowing what to do.

I'm starting to think that the reason Jeep didn't offer 37's from the factory, to match the Bronco, was because they knew the added strain on the steering components would be too much for their steering box. I'm not defending Jeep... but even PSC upgraded their valving for their 392 steering box!
Have any of you weighed your Jeeps lately? I weighed my Jeep, back when I was on 37's, and the vehicle + recovery gear came in a at little over 6,300 lbs, which was ~1,000 lbs over stock... and that was without any passengers in the vehicle!
When I moved to 1-tons and 40's - I also did PSC's full kit... Steering is not a sexy upgrade but it was a necessary one. PSC does have some less expensive options that only replace Jeep's steering box and don't add hydro-assist. Have any of you looked at any of them?

On mine the only thing I’ve done is upgrade to the factory 35’s that are offered on the XR 392 because it wasn’t available when I ordered mine. I don’t think the power steering is getting hot, at least not in my case. It was throwing the error message on a cold start up lately and just recently every time I drove it along with the battery light and voltage spiking over 15. I just tightened the ground behind the rh headlight and it worked flawlessly today. The ground really wasn’t noticeably loose but I bet they must have poor contact from the factory due to paint maybe?

Yes, and I also want to mention that I have no affiliation with PSC... I'm just a happy customer.
Here are the three options that PSC has on its website. I believe that #1 and #2 can be run as a stand-alone upgrades... but you should call them to confirm.
