After 2 full days at the dealership and working with Jeep engineers, they still don’t have an answer regarding what happened or a resolution to fix the problems I experienced . Also, I was told @ Jeep Cares would contact me and someone there for a lack of better words would be “assigned” my case.

Basically some excuses so far about it being something they can see as having happened based on the 20 + fault codes in the diagnostic but unless the issue is “active“ Jeep engineers are not particularly helpful in locking down what’s wrong. Basically they want me to approve letting their tech drive around my brand new GC until the problem can be replicated. Just fantastic. I said I am not authorizing anyone to drive my car back and forth to their home. Also - finally got the Service Director involved and he’s going to get me in a loaner while they continue to sort it out. My guess is I’ll get it back with nothing having been done to address the root cause of the problem and will have to drive it until it flakes out again and will need to have it towed and hope they can manage to get more insight off the computer. Just wonderful.

 

Well, good news! They feel confident they found the issue and have addressed it. I picked the GC up yesterday afternoon. The tech was able to replicate the problem on short drives in the parking lot and around the dealership which helped with their trouble shooting. Here is a condensed version of the description off the invoice.

Perform DTC Inspection - Verified concern, found multiple loss of communication faults in the system, traced root cause to faults U110a and U0131. Performed diagnostic procedures. Per the fault diagnostics started by checking connector connections and pin ends. Checking C1 and C2 connections along w corresponding pin ends. All check good. Opened Star Engineering case. Was given main wiring connections in the front end of the vehicle to inspect. Those checked good. Test drove vehicle in a controlled area and vehicle died out while test driving. With the tech seeing what was actively happening, tech decided to start by checking / load testing the batteries. Both failed. Removed and replaced both batteries. While replacing batteries, checked ground connections. Found main ground to vehicle and IBS not seated fully, then found routing of the cable routed incorrectly (this created unnecessary tension on the connection) Removed ground cable and routed correctly. Made sure ground cable was securely mounted on ground post. Reassembled, cleared codes, tested, all ok.

See pics below from service manager:

Cables before their inspection, INCORRECTLY routed

Cables after inspection, CORRECTLY routed per Service Manager / Technician

 

Great Post - Unfortunate but at least they found the issue - Good Luck moving forward ✌

 

It’s crazy how much more complex vehicles have become these days. I’m hopeful the root cause of the issue has been found. I’m just happy I got lucky and was able to get the steering wheel unlocked and drove it about 50 miles back to the dealership by my home without incident and avoided a tow. Glad it happened to me and not my wife.

 

Agreed - Simply way too complicated - You know we are in trouble when you can’t even check the actual radiator without removing the lovely skirt that closes everything up in the engine bay - They don’t want us touching these vehicles and they are impossible to self service. ✌

 

OP, thanks for posting this thread and update as it could help others maybe even myself some day.

With a 2022 the batteries likely tested bad because of those bad grounds which can cause all kinds of other problems like those CELs.
A computer is only as good as it B+ supply and grounds.

I'm sure the tech got a bump up on his learning curve too.

Regarding your thoughts on the batteries, I had the same discussion with the service manager at my dealership. He also felt the bad grounds had impacted the batteries and the fact they tested bad. He also said they erred on the side of doing right by me moving forward with replacing them given the circumstances. So, that helped ease my concerns about the vehicle somehow exhausting batteries in less than a year. I‘d say of the 8,700 miles on it, we are very balanced between local knocking around and highway miles.

It was crazy all the stuff that bad ground impacted and your point about the tech getting a good learning opportunity that can benefit others as well is a good one. I mentioned it in our communication as well as they pushed forward on working towards a resolution.

I was definitely assertive in the discussions I had calling Jeep Wave / Cares, opening a case with them, and with the service team at the dealership but never got out of line. After their handling of the situation, I have more confidence in them than before so I think that is a win on their end. I’m glad I got a Star Tech involved and my case manager w Jeep Cares (nice job Ira) was very helpful and said this was not the first time she had heard of WL owners having a similar experience.

 

Both. When the aux batteries die, they often take out a good main battery with them, but even on the vehicles without aux batteries (4xe wranglers and 392 wranglers, for example), the main batteries often die very, very quickly. It's not unusual for 6 month old vehicles to have the 12v battery die.

True batteries tend to die earlier in hot climates like Phoenix, AZ.
But when a good new battery dies in 6 months there's something else going on to cause that.

 

So...evidence? 'Cause that's not really been something that large numbers of folks have claimed here over the years and I've been in this online community for over ten years now. People with problems flock to forums to complain about stuff like this. I sure doesn't seem like there are any more battery failures that is likely expected for "such a thing" give there have not been large numbers of complaints to my observation.

 

I'll see if I can find a copy of the tsb that jeep has issued to dealers specifically dealing with this.

 

Tyler-98, Thanks for posting. So when it comes time to replace the batteries in my 2022 WL Overland on my own dime, it sounds like Odyssey might be a brand worth considering in your opinion as an OEM replacement / upgrade?

I've only run Odyssey or Northstar for the past 10 years, Northstar was bought out by Enersys (who makes Odysssey batteries) they are extremely good batteries

 

Back in the day, if your battery seemed like it wasn‘t performing up to snuff, you just popped the hood and checked the + and - terminals to make sure they were good and tight. Maybe disconnect an hit the posts w/ a wire brush. Swapping out for a new battery was a piece of cake. Now, I’ve got 2 batteries buried under seats and interior trim. On top of that I’ll probably have a bunch of hoops to jump thru to make sure the whole damn vehicle doesn’t go into some crazy state of paralysis as part of the process. Will definitely be looking for a well done DIY WL battery replacement thread to bookmark at some point.

 

Yeah these new vehicles are definitely not DIY friendly.
There have been a few threads here when replacing the batteries the OP'er accidentally shorted those under seat battery's wiring to ground blowing the fuse and worse.

2 batteries + under the seat + replacement + tight work area = DIY PITA

 

FWIW: The OEM battery in my wife's 2016 Durango R/T failed after 26 months (April 2018) at 39k miles. The Durango battery is installed under the front passenger's seat like a GC. It was replaced under warranty with another OEM battery, and is still going strong today, 5 years later, now with 115k miles.

 

Good post thanks. I have a JK 2018 Wrangler bought from new (demonstrator) so out of 3 year warranty now. I have a starting problem every 20 or 30th start. Turn the key and ding ding ding. Have to wait for 5 minutes or so (as if I have to let it cool down) then it turns over fine. Sometimes it will start if I am on a slope and I let the handbrake off while in Park so it rolls forward slightly. Am told 2 different reasons from 2 different branches: A sticky starting mechanism in the transmission is not recognizing the vehicle is in park so a mismatch in communications. The other branch: Not that, as they could not throw up any diagnostic codes when they did finally get it to fault. Because there is feed back through the speakers when it happens, they now believe the problem lies with my Nakamichi stereo system/ reversing camera combo. Of course this is costing me every time, although the vehicle is pretty new at only 7900 kms. Additionally more failures are happening which may or may not be from the same cause: Heater stopped heating, phone stopped connecting, underside steering wheel buttons for radio volume not working. I am interested in the idea that this is battery failure but I have had it tested 3 times now and am told it is fine. I have no stop/start battery. Any comments very welcome, thanks!

 

Linz - I wish I had a solution for you. Maybe check out Tyler-98s post in this thread. I suggest that because he mentioned batteries that might test as Ok but remain problematic when it comes to some other vehicle systems. Maybe check or have connections at the terminals checked.

 

Thanks a lot. Yes I did read that post. I will do a battery swap and let the forum know later. Cheers!

 

If some failure happens once and never again, yep could be an unexplainable glitch.
If the failure happens repeatedly, nope there's a problem that needs to be resolved.

Fortunately a lot of these so called 'glitches' on new vehicles turn out to be SW bugs easily fixed with a SW update.
Problem with that it takes time for car manufacturers to accumulate a number of like failures before their engineers look into it.

 

It‘s only been 10 days but no issues w/ the GC since I got it back on 5/5.

 

Welp, I can tell you it was about the same timeline for me until the exact same problem popped up yet again.

 

Oh man. l‘d be frustrated to put it nicely. I told them I wanted everything well documented in case I had to go that route as well. I hope they can get it straightened out for you soon. Please post diagnosis / resolution when you have one.

 

Thank you, and will do.

 

Sounds very similar. Did you get stranded somewhere or were you at home?

 

First start of the day in the morning, at home both times but had somewhere to be

 

That’s eerily similar to what happened to me...except I went straight to the dealer w/ it so never saw the CEL clear. It was still lit up when I dropped it off. Curious to know what they did the first round on yours. Did they replace batteries and/or note and change the routing of those grounds / wiring harnesses?

 

These cars are so electric/software heavy which makes even someone like me whose mechanical savvy worry.

 

Agreed on “software glitch” diagnosis as being disconcerting. Hope it gets resolved soon and with more clarity on the causation.

 

What a shame what has happened to this truck.

 

Sorry man. What a mess. Let us know what they eventually come up with. Where would lemon law apply, the state where you purchased the vehicle or the one where you have registered the vehicle?

 

For me both are the same - its NY.

Take a look at the below article, pretty much describes the issue to a tee, and its not pretty.

Power Steering Problems

Almost all of the complaints listed as steering issues involve power steering problems. Some complaints state that drivers suddenly lose power steering, usually along with other driver-assist functions like lane assistance and forward collision control. Others say that power steering simply failed, while others refer to a power steering disconnect.

With only 173 miles on a new 2022 Grand Cherokee, an owner from Colorado went to start the SUV, and “the power steering, electronic stability control, blind spot monitoring, and lane assist lights all went on. The power steering didn’t not work and I was unable to back out of my parking space. I repeatedly turned the car on and off and the lights persisted for at least an hour. After an hour, all lights went off and I was able to drive the vehicle. This could have been extremely unsafe if this had occurred while the vehicle was in motion. This also was problematic as I was stranded in a parking lot late at night.

“I immediately took it into the dealer and they cannot reproduce the problem. I am driving a loaner as I do not feel safe in the brand-new vehicle. No warning lights came on prior to this problem appearing.”

Holy crap. That’s basically the exact same thing I experienced, I got mine back into a state where it unlocked the power steering after 20-30 minutes of starting up / powering off in my parking lot an hour from home. Highway speeds about 90% of the way home. Little did I know it could also occur while driving as noted by the dealership when they were working to reproduce the issue as well as by others as noted in the link you shared. Now I’m stuck driving it around wondering if it’s really fixed or could unexpectedly happened again at any time.

 

As mentioned in my post above, I was having the same issues with my 2022 Grand Cherokee with multiple electronic system failures. After almost 2 years back and forth with the dealer, it was determined to be a faulty IBS (Intelligent Battery) Sensor. The sensor was back ordered as there was a nation-wide backlog of orders for this part (No kidding!!). The sensor was replaced and everything worked fine for a few months, then I started getting "key fob not detected" errors. This caused the theft alarms to start blaring as well. After multiple tries over about 30 minutes it finally started. This happened to me multiple times, but twice when I had my young grandchildren with me in freezing temperatures. Totally Unacceptable!! Then, I started getting multiple system failures and it seemed as if EVERY system that could possibly fail showed up on the display including Power Steering failure. This meant that the vehicle was not drivable as the steering wheel would not turn. After only owning this vehicle for 2.5 years I had finally had enough and no longer felt safe driving it. If I had known that 2022 was the first year of the re-design of the Grand Cherokee I would have waited for all the bugs to be worked out before purchasing it. Once all of the errors cleared, I traded it in for a new 2025 Grand Cherokee. Now it is someone else's problem!!!!!

 

There was also a recall posted yesterday

Jeep Recalls Grand Cherokees That Could Lose Steering Control - Consumer Reports

Jeep is recalling 2021-2023 Grand Cherokee and Grand Cherokee L SUVs because a part of their steering systems could fail and cause a crash.

Sounds different but yet another concern to worry about. Thanks for posting.

 

....crickets

 

14 total days at the dealer.....crickets

Curious, does how long they have the vehicle have any impact on the strength / validity of a lemon law claim where you reside? My sense was here in IL that it did not. Focus seemed to be 3 failed attempts to fix a problem w/ in X days from time of sale.
