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.

I have 2020 LTZ with 6.2 engine that has this front diff. Jingle. Truck has 2500 mi. Started showing up as outside temp got warmer. Goes away in auto mode or 4WD

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.

    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
