Having a issue with weird glitches

[Tyler88]

I am not sure if it is an update issue but I have had a similar problem before and the dealer supposedly fixed it by manually updating the Uconnect, but I have a 2018 JL with the 8.4 Uconnect and about 2 weeks ago I got in to start the car and it showed I had 999999 miles on the car and I was only able to fix it by locking the car and walking away and going to start it again. Then this week I had the same mileage problem and fixed it, the day after my speakers would cut out every 5 seconds and the back up camera would just be a blue screen and say “Camera is Unavailable”, but again it went away with the locking and walking away and then going back and starting the Jeep again every thing is fine now but I don’t want it to randomly come back like it has been. Please let me know if anyone knows anything because I would prefer not to take it to the dealer if I don’t need to.

From reading various threads, the most common causes of weird electrical issues are fuses that aren't pushed in all the way (they can get loose again, so worth the minute it takes to check), or your aux battery is going bad.

Ok thanks I will check that

Tyler,

This is a potentially serious issue (at least for Stellantis). If you can reproduce this issue regularly, I wouldn't be surprised they'd want to buy your vehicle back. Or at least have it available to them for awhile.

Changing the odometer (for any reason) is a serious legal liability issue. Odometer tampering is criminal everywhere. From invalid resale value to warranty fraud, the odometer value is typically implemented in at least two or three separate and distinct places. The engine, transmission and body control modules all have functionality to detect potential tampering. If any one differs in value or suspect unauthorized access, a fault code is thrown indicating possible tampering. Do you have any fault codes present?

For the cluster to indicate an invalid value is something, I think, would be very important to them in understanding why. It very well may be that '999999' is a diagnostic 'flag' value but regardless the normal odometer anti-tampering algorithm is not happy.

Do you have anything installed that bypasses your Security Gateway Module such as a Tazor? If you do, you can't rule out that your vehicle may have been hacked. However unlikely, sophisticated bad actors are unfortunately only getting more and more nefarious. Have you any hint of a recent break in?

With a cellular connected UConnect 4 radio, it is possible that your unit's MAC Address has been compromised allowing someone in to your system remotely. While very unlikely, it's still not a zero probability.

So you may not just be encountering a technical glitch but something more sinister, like a key sniffer. Unfortunately, most dealerships are likely not trained in these matters.

My suspicion, if you believe in a tin-foil hat scenario, is that your radio may require a factory default reset, or maybe even a complete reprogramming and not just an over-the-air (OTA) update.

Hopefully I'm wrong. But it's something to consider.

I have no taser installed or anything like that everything is stock. The only thing is I have not been able to figure out what caused the problem so I can’t really reproduce it but next time if it happens again, I will go into the dealer and see if they can check it and see if they can find anything

Battery?

Also I am leaning toward it being something not that big since I don’t think I would have been able to fix it and get my normal amount of miles to show up again

That's a good start. Are there any stored fault messages displayed on your cluster's EVIC screen? Do you own or have access to a fault code reader?

Without knowing the intricate ways developers can display subtle internal problems, noting that I've been out of the Engine Controller development business for a little while now, the '999999' value may not be odometer tampering but some subtle mechanism for another feature which has been implemented outside the control modules and inside the radio itself.

The only way to truly 'know' this information is if it's been documented in a Service Manual (SM). But the only way to research that is to either pay for a SM subscription (not cheap) or take it to the dealer (also not cheap). Reputable third party repair shops also may have access to these SM's, so I'd recommend calling around and assess your best options.

I will probably just have the dealer look into it since I still do have extended warranty which covers mostly everything

Also there is no service messages or anything
