Ive had a variety of issues on my Wagoneer, but the funniest is probably the seat heaters shutting off. I brought it in immediately after purchasing when I noticed the front seat heaters were turning off after 5-10 minutes. It didnt always happen, but it happened a lot. When they turned off, they wouldnt turn back on immediately. They had to cool off, and then you could start them up. There was a wiring issue the dealer found and fixed. A week or two later, I noticed it again. Unfortunately my car broke down before I could get it in again. In dealing with the larger breakdown issue, Wagoneer Customer Satisfaction reached out to discuss the seat heaters. They mentioned it was a known issue that should have a fix coming in January, but to "just run them at medium heat or low and it wont happen." Obviously I was pretty upset to hear this, given how much the vehicle cost and the fact that it is winter. I asked if someone bought an Escalade if they thought Cadillac would tell them to run the seat heaters on low. They didnt find that funny. Getting it back from the dealer for the third time on this one, this time with advanced support from Jeep. Well see how it goes.

Sorry to hear about the issues with the seats @Rnichlsn. Did they tell you what the fix was supposed to be for them that's coming in January?

Also, what was the "larger breakdown issue" that happened to your Wagoneer?

No, they did not. They just said it was a known issue and that something was supposed to come in January. However, I worry its just something that lowers the heating levels of high so that they just dont heat up as much and power down. I hope that is not the case, but their advice to me was "just dont turn them on high" which is frustrating given how much we all paid for these cars. The larger breakdown issues were computer meltdowns that happened on startup. All of the lights and computers in the car started flashing. The running boards stopped half way up. Everything just broke and required a computer reset before it would work again. I listed out in a separate post.

Me and my wife noticed this happen today while driving. Now the rear seats didnt shut off or the passenger didnt shut off just the driverside and you couldnt turn them back on until we came to a complete stop. Its weird. Not sure if it correlates to the auto start stop

It only happens to the drivers side on ours. If it’s on high it will shut off after 3 minutes. Then I have to wait about 7 minutes and turn it back on. Our dealer said to keep it on medium or low until the push the software update. It is very frustrating! We are having other issues as well.

Happens on both driver's and passenger side front seats on ours. Does not seem to correlate to any amount of time--they can turn themselves off after two minutes or stay on for hours with no detectable pattern. Unfortunately, we're dealing with a bigger problem, amplifier battery drain, so waiting until that is resolved to try to troubleshoot the seat heaters shutting off.

We drove our '22 Wagoneer out to Cali in November from Texas. I didn't notice any issues, but had driver seat on medium most of the way. The last couple of weeks we've noticed the driver side heated seat shutting off after one or two minutes on high and the option greyed out on the Comfort screen. It becomes available again after a few minutes of cooling down. Def seems like a safety/software issue. The passenger side has no problems. I'll check for a loose connection below the seat and see how it does on medium. It's definitely annoying now that it's cold out.

Recently took my GW series I to the dealership for software update. Now all of a sudden the issue with the driver side heated seat shutting down after a minute or so is occurring. So frustrating this is the third software update in 3 months for other issues.
The issue wasn't occuring until I had a software update, so now back to the dealership.

My parents Wagoneer 2 has the seat heater issue. Shuts off. Tried putting on low and med and still shuts off. Had power steering quit the other day. Shut it off at dealer after shutting it off three times on the road and then power steering started working again and the seat.

I'm seeing this heated seat issue on my WSI too. Never had a problem the first few months I had it, but now that it might actually be cold outside the heated driver seat often turns off. Tried the lower heat settings and it seemingly makes no difference.

Does anyone know if there's been a fix for this?

I too have WS1 and both my wife and I turned on the seat heaters but we live in AZ and out butts got too hot really quickly so we turned it down to level 1 and we didn't notice it getting shut off. The car is still very new so we will see how it goes. we care about seat ventilation more than heating due to the weather and I hope we don't have issues with that.

There is aTSB/RUS 22-026 on the seat heater sensor module, this is a software update. If that doesn't work it is possibly a bad element that is being tripped by safety circuitry (to prevent overheating) they issued a TSB/RSU on this as well 23-006-22 which calls for replacement of the seat foam, seat back, and heating element. (subject to parts availability)

Appears that the software update fixes most, my passenger seat started acting up after the update. My sever is there is a sensor in the seat that shuts off if it can’t detect weight. Like DillonJm dealer us replacing the heating element in the seat back snd bottom. Apparently this is a complicated task (took 3 days), picking it up in AM.

Has anyone had full resolution of the issue yet? Ive been at this for over a year with my Wagoneer Series II. Getting really frustrating at this point, and the dealer I’ve been working with has basically become unresponsive. Trying another dealer this week but I’m afraid I’ll be starting from square one. At this point, I don’t understand why they don’t completely replace the seats with new ones. Over a year to fix this issue is completely unreasonable. If the newer models arnt having the issue, give us new seats. This is insane. Also, sort of on the same topic, does anyone else feel tge ventilated seats are garbage? I tried using them all summer and noticed the cooling maybe 2-3 times. Most of the time it’s just unwanted noise. Does anyone know if this is related to the heated seat issue? The dealer wasn’t exactly reassuring about that issue.

Got it back. Saw pictures of inside of seat - very complex to say the least.

Zero idea if it’s perfectly fixed or not until a road trip this weekend.

I have had a lot of high end cars and the seats are better then most (at least they aren’t to hard or cut for weird body sizes.

I’d be less annoyed if the free loaner cars actually existed.. but Lincoln has the same problem, they advertise something and the dealerships don’t or won’t deliver because the program is badly designed.

Well, I dropped off my Wagoneer this morning at the new dealer. Hopefully they can resolve this for me. On a positive note, my loaner was a new Wagoneer Series II. First time that’s happen in the dozen times I’ve brought it for service. Hopefully it’s a good omen.

So far so good! They had it for almost 2 weeks waiting on parts, but the heated seats seem to be working perfectly now. I don’t want to jinx it though. In the back of my mind I’m expecting them to start failing again at some point. I guess the real test will be if they hold up a whole season once when I start cranking them again next winter. But as of now they are fixed 👍🏻

Cautiously optimistic lol. They went out of their way to fix the problem, had the Wagoneer loaner for me the whole time it was being worked on, and were very communicative throughout the process. I was initially feeling good about the last dealership as well though, so hopefully this is a pans out better.
