Did GM purchase your truck back from you because they could not fix the differential  noise or did your truck have other issues as well. Just wondering because my truck has the differential  noise as well along with other issues.

My repurchase was solely based on the differential and drive shaft noise while in 2WD /Jingle.

Ok thank you. Stub shaft,singer,seal have been ordered since October for my truck and stub shaft  has not come in. My GM advisor has not contacted me since October.Gm advisor did tell me in October they did not have a fix for this. I guess my next step is a attorney. I have a log and all recepts of this whole mess. Truck will be a year old in June. Thanks again.

I would go and check out your states lemon law first before getting a lawyer. FYI one of the GM reps “John” assigned to my case was fired from GM around that time frame and I lost communication for awhile also. You may have been dealing with this same guy. Google the BBB auto line and get the case opened with them first. This will cost you nothing and it did work for me. Please feel free to message me here if you need help.

I didn’t win my case yet. I hired a lawyer and they contacted gm several times. Gm never responded so now we are taking them to court. My truck has more issues than just the differential. Check your state laws like others have mentioned.

Yup! Now that the weather will be warming up soon the jingles get more predominant.

Has anyone with a 2020 had this issue?

No. The new 2020 is jingle free.

Not entirely true.  My 2020 has 2260 miles on it.  Built in 8/19.  Picked it up in the beginning of December.  I don't drive it that much, which is to say a few miles a day maybe to the gym and back, no really long trips.  Last week, I was driving around all morning and started hearing a thunking sound.  So while I had the radio off listening to that, I heard the dreaded jingle.  Jumped on here and they symptoms are exactly the same.  Starts around 15-20 miles, only in 2wd, goes away in 4x4.  It does have the SU4 axle.  Anyway, took it in and first they didn't hear it.  Went back the next day while it was warm and took the tech for a ride.  He heard it.  It goes back in Tuesday.  As far as the thunking noise, it sounded like the front but closer inspection showed it was coming from the rear leaf springs.  They said installed "Rear Leaf Spring Insert Replacement and Re-torque u-blots as per bulletin"

Me.  2020 build date 8/19.  Same symptoms.  Same SU4 axle.  Goes back in Tuesday next week.

I have the clunk just had it in to the dealer and of course they said they couldn't reproduce it. Please keep me posted.

Initially I thought it was from the front.  So did the tech.  Closer inspection and he was able to find it in the back.

Yes that's the sound and about the right mileage too. I have 3900 miles on my new truck and so far I have yet to hear anything.

Dealership told me they were going to replace axle on that side. They are going to let me know when parts come in. Is this a fix or just fishing? I have not read all 54 pages related to this issue, just trying to find out what has worked for other people. I would appreciate any advice. Thanks

Unfortunately fishing mostly.  But you have to play the game at first and who knows it might work.

    • Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
    • Paid $2.72 for E85 today.
    • Welcome back! No, it definitely doesn't pass the sniff test. Even "ceasefire" needs an alternative definition these days.    $5.29 at Kroger today
    • That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
