BEWARE: 392 Engine warranty denied at 2,100 miles by Jeep/Stellantis

A yearly oil change on anything valuable enough is a good habit. My father-in-law does this on his tractors and other machinery. My buddy has 15-20 dealerships and he would go nuts if a car was sitting for more than 6 months.
the op is trying to make the connection ,of a 6 month oil change higher standard for customers , 23 months and 6 months and however many days over, is not even close to the same , they denied him for stupidity ,i have yet to see anyone woth a 7 month or 1 year oil change with a seized engine and denial . there is ov wiggle room at month 6 and say 10 days and a blown engine ,23 months plus is not even remotely the same ,they denied him for being stupid ,and the guy hung up the phone beacause he was trying to make that correlation .

If you are going to troll at least keep it within the point of the post to avoid looking daft.
 
Here’s a screenshot of the maintenance schedule I’m seeing on the app. 6,000 miles or 6 years. :ROFLMAO:

That did make me curious as to how many times the Jeep had been into the dealership service department without anyone mentioning that it needed to be serviced.

Absolutely, if I were a Jeep dealer I would want to be avoiding cars that sit on the lot for extended periods of time but unfortunately it does happen, and there is zero policy from Jeep/Stellantis to change the oil in it before a customer drives it off the lot.

  • Long sales times: Some new cars can sit for over 250 days.
 
For the older vehicles....I just buy the oil from wally world and do it myself. The Jeep has to be the easiest oil change to do. "It is a crime" to take it in to the dealership ...but still cheap insurance.
Looks like you can still do your own oil changes on new vehicles but you need to jump through a lot of hoops:

How to protect your warranty
  • Follow the service schedule: Make sure you perform the oil changes within the intervals recommended by Jeep.
  • Use the correct oil and filter: Always use the specific oil type and grade (e.g.,
    0W−200 cap W minus 20
  • or
    5W−205 cap W minus 20
    ) and a filter that meets the manufacturer's specifications.
  • Document everything: Keep detailed records, including:
    • Receipts for the oil and filter purchases.
      • A log of the date and mileage of each oil change.
      • Consider using apps like Carfax Car Care or the manufacturer's app to record services and upload photos of your receipts and odometer for a digital record.
    • Be prepared to prove it: In the event of a warranty claim, you may need to prove that the maintenance was performed correctly and on time. While some sources say a dealership might need to prove you caused the failure, having complete documentation is the best way to protect yourself.

That’s my whole point , ur trying to say it’s to warn others , it’s to make the correlation of 6 month oil changes to your situation. U tried to do it on the phone with jeep , and he hung up ,because it’s not even remotely close
 
After months of run around, and the Jeep sitting outside, I was told that Jeep refused to cover it because I did not have "service records" showing that the oil changed every 6 months.
**Edit - never mind I see that you had not changed the oil since purchasing. Thanks for the warning because before reading your post I was comfortable with every 5000 miles or 1 year whichever comes first and now I see that is not correct. Best of luck getting this issue taken care of for your 392.**


If I might ask, you say warranty was denied because of no service records. Question, had you changed the oil every 6 months or had you not changed the oil since you purchased in 2023?

I purchased a new Jeep Wrangler Rubicon 392 in May of 2023. Woot woot! This was strictly a recreational vehicle, and not my daily driver, so it only had 2,100 miles on it by April of 2025. That is when tragedy struck, the motor straight seized up! No problem right, it is still under warranty and only has a handful of miles on it. I took it to Heritage CDJR of Logan where I bought it for warranty work. After months of run around, and the Jeep sitting outside, I was told that Jeep refused to cover it because I did not have "service records" showing that the oil changed every 6 months. Surely this must be a mistake right? Vehicles sit on the dealer lot all the time for extended periods of time and there is no policy from Jeep to change the oil when purchased. I called Jeep Customer Care who told me that they dealer had placed the restriction on the Jeep and they were the only ones who could remove it. I went back and forth between Jeep Customer Care and Heritage who kept pointing fingers at each other. Infuriating. Finally Jeep Customer Care suggested that I take it to another dealership and they should be able to lift the restriction. I should point out that the restriction they are referring to is over the ENTIRE Jeep. Any warranty work that needs done to this vehicle from here forward will face strict scrutiny from Jeep because I didn't change the oil every 6 months. Yep, if the dash goes out, or the window won't roll up, the warranty is flagged by Jeep for additional review.
I ended up putting the Jeep on to a trailer and driving it 100 miles to Larry H Miller Jeep in Sandy. The service team at LHM said that they would work with Ryan Lamb, the area manager for Stellantis, to see what they could do. Perfect, finally we are working with a live person in customer support and retention. LHM eventually told me that Jeep still refused to do anything on the warranty so I asked for a conference call with Ryan Lamb to explain the situation. It did not go at all as I had imagined. As soon as the point was brought up that Jeep dealers are selling vehicles with "expired oil", by their own standards, Ryan became aggressive and audibly upset to the point that he was yelling over me trying to speak. He could not, or would not, answer why customers are being held to a higher standard than dealers. In fact he was so agitated that he ended the call abruptly. Wow!
I'm still searching for the answer to my question as customers are buying vehicles with expire oil, or nearly expired oil, every day by Jeeps definitions. Since the call I have tried reaching out to Jeep Customer Care who will only send me to Ryan, not his superior, and Ryan will not return my calls. I have also tried talking to Jon Weece - owner of Heritage Auto to see if he could move me up the food chain so I could discuss Ryan's behavior and ask the unanswered question - so far no luck. I have also tried reaching out to Ryan directly who has blocked me. You can reach Ryan Lamb,Metro Area Manager at Stellantis, on LinkedIn.

I realize that the warranty is voided by my inaction. That is not the point of this post. The point of this post is:

1 - Help others from making the same mistake.
2 - Get an answer to why Jeep is selling vehicles with "expired oil", by their own definition, and holding their customers to a higher standard for oil changes than they are their dealerships?

In the end, I had to replace the 392 engine and am still without my Jeep 7 months later as the dealer has yet to get it running. If anyone has any other contacts at Jeep/Stellantis, or ideas on how to get this question answered, I would love to hear from you.

Thanks for coming to my Ted Rant.

BEWARE: 392 Engine warranty denied after 23 months of owner neglect​

(Corrected title for ya)
 
this thread is pointless.
OP, change your oil following owner’s manual or have someone do it.
If you’re posting to “warn” us that vehicles sit on a lot and you aren’t sure if they’re serviced in a “timely manner”, then change the name of your post to something like “are new vehicles serviced on lot?”

LOL, that's what they told us about vaccines too. Still not poisoned by the Gov't here. Ha Ha.

Hold onto your panties, just joking...

A rose by any other name
 
I think @Boo392 makes a valid point about dealers not following the same 6mo service interval as the owner's manual recommends. The oil really doesn't expire (I can't find a use by date on the side of a bottle of Pennzoil ultra platinum full synthetic 0w-40). Pennzoil suggests the shelf life is 4-5 years if stored at 40°-85°F. But the real problem is corrosion. As an engine sits, parts (especially the cam shaft) lose their oil film and start to oxidize, same thing for the cylinder walls. Not good. The real issue with oil getting "old" is water (a byproduct of the combustion process). You change synthetic oil at 6mo because you are removing contaminates, not because the oil "expired". I just bought a "new" jeep and while I was looking it over with the sales guy I asked him how long it had been on the lot, he said it was "brand new... just came off the truck"... so I went to the driver's door inside sticker (the grey one next to the tire pressure) and checked the build date. It will tell you the month/day/hour of production. It was 4 month old with 23 miles. Here is an example:

So when we negotiated I asked them to do an oil change. Otherwise they would not have done that. On my 392 I picked it up new and have kept to the schedule in the book. Just worth mentioning that even if you do you own work you can still document it on the MOPAR vehicle service record. I've been rotating my own tires so I added a record:

As far as the warranty that seems to be very clear.

I'm not a lawyer but I don't think you can argue that you didn't do your job because someone else didn't do their job. Seems like you bought the wrong vehicle. If you take care of that 392 it'll take care of you. To paraphrase Ford vs. Ferrari... take care of the maintenance then drive it like you mean it.

Wow! Sorry to hear that this happened to you, what a nightmare. I do know that the Jeep app allows you to record oil and filter changes along with the mileage and date of when it was done. I change mine often and record the service in the app religiously.
Where/how in the app do you record oil changes? I’m only seeing oil life remaining?

In the Jeep app, you select 'Service and Maintenance' and then the 'History' tab. At the bottom there is a 'Add a Record' that you can use to put in your own records.
 
Sorry this happened. Personally I would not have pointed out their practice of not changing oil in cars on the lot. That steered the conversation from your Jeep to a much bigger issue that they cannot acknowledge without implying some liability.
I understand the ChatGPT post from above with some exception. Even if the engine has a million horsepower, it doesn’t change how the oil degrades when the engine isn’t running.
I would say the oil degradation is a result of the vehicle sitting outside at their lot and short drives followed by just sitting. Water accumulates in oil with extreme temp changes and short drives.
They cannot void the entire jeep warranty due to oil. They have to prove what you did caused the issue. Your oil doesn’t affect windows or electronics. That’s the law and if they deny an unrelated claim, that’s a lawsuit. Once they replace the engine, you should be fully covered. I first changed my oil at 3000 miles and then always less than their recommended interval.

Have the oil that is in the engine tested by a valid oil test lab or two to confirm exact condition of oil...if oil is within specs, sue Cheap Jeep's arse off...get the oil sample from a clean area of the engine...I.E. Filter, Cooler, etc...
