Power steering pump overheating issue on 2020 Eco diesel.

[grimmjeeper]

The dash lights up like a Christmas tree and the message center yells at you. Had this happen when my Jeep was a few days old (on 35’s) in Moab at 105° and a few days later on Imogene pass at 60°, but obviously very high elevation. Didn’t lose any performance, but wasn’t a fun experience seeing all the lights in a 3-7 day old Jeep. I’ll be adding additional cooling at some point, likely when I go to 37’s or bigger.

That sounds like loose fuses. Have you checked them?

I've wheeled with my 37s several times now in ambient temperatures exceeding 100 degrees and at elevations exceeding 5k ft. I did Imogene, Black Bear, and Ophir Passes last October, but was still on the OEM wheels/tires. I have not had any trouble . . . yet.

yep, but don’t remember if that was before or after I seated them all.

I went to Silver Lake Sand Dunes and Holly Oaks this weekend. I got the overheat warning only once during a slow crawl through some brush. Temp was probably mid-80s. I'm stock w/ 35". Will keep an eye out.

I have experienced the same problem. I had my steering gearbox replaced last December. Never overheated until May. It was about 100 degrees and dry. I am in Texas and while climbing a really difficult area the lights lit up and stated the steering was overheating. I just parked for awhile and let it cool down. So far it hasn't happened again, but I was really pushing it that day.

It isn't fuses or anything else...just hot as can be under the hood. I installed hood scoops last week so I will see if this helps.

Happened to me this past July in Moab. No issues in Ouray/Telluride/Silverton.

I have had this issue twice. The message came up while I was on a steep rocky trail that required a lot of steering. The message of steering system is overheating and may effect performance. I saw no problem with steering and as soon as I turned off the engine the message went away. Same story when down at corral canyon. But it was close to 100 that day. I asked the service people about it and was told that this is common but to keep an eye on it if the message doesn't go away after cooling down.

I too have experienced this problem while out on the trail. It took me a bit by surprise as I did not think it was a strenuous day on the trail (Turkey Creek, near Cleator, AZ) . . . ambient temperature at the time was 93 degrees and elevation of about 3K ft.

Steering performance WAS NOT affected despite the dash warning light (which indicated steering MAY be affected). As soon as the dash notified me of the problem, I looked at the OffRoad pages gauge cluster and saw oil temperature was a moderate 233 degrees, coolant was 221 degrees and transmission was under 200 degrees. I activated cooldown mode feature of the Tazer JL Mini non-menu live function (which turns the engine fan on high) and within 5 minutes the steering icon warning light turned off, and did not return for the duration of the trail run.

I had a similar issue when navigating a long and steep shelf road early on in my ownership. However, it happened when I wasn't using off road plus and was trying to manually disengage the ESC. I had a hard time navigating the obstacles and received the power steering overheating message consistently on the trip until I started using off road plus and manually shifting up obstacles in 4H. I had the same issue in 4L too. I now use off road plus every time I am navigating any obstacles and haven't encountered the issue since then (except on very technical wheeling that absolutely requires 4L). Could be coincidence, but its worked so far.

What's off road plus?

What's off road plus?

It's a mode offered in the Rubicon models. See below thread on this topic. It's also described in the manual.

Sadly I have the 2020 which doesn't have this option.

Mine overheated a couple times when I was riding around on the alpine loop during the summer. Seems to be common

Hey Everyone,

Well, after two weeks in Moab I did experience some steering issues. No overheating warning lights; but, the steering operation wasn't as smooth as before the trip.

I've been cycling the steering and removing/replacing fluid in the reservoir in an attempt to get the fluid back up to virgin condition.

I just wrote Hayden this morning about options for a cooler. The long heat sink cooler that is popular on the JL is going to be tough to mount with the bumper that I have, and the winch.

Ours is a 2021.
