Well my new 2020 started making the noise at the 14,000 mark. Has been good until today. GM is a joke. It’s been over a year with no fix for it. Beyond ridiculous.

As far as switching an su4 for su5 axles, I was told that the parts have to match whats on the build sheet.

Seems to me that if GM was looking at saving their reputation, customers and vehicle status, they would pay the lesser of what it would take to fix the vehicle. If they are unable to repair the vehicle by fixing the SU4 axle, it would be cheaper to replace the axle with the SU5 axle that has no issues than to face a barrage of Lemon Law suits. Most of the time, a Lemon Law suit that does not go the customers favor, that customer goes and buys a truck from a different manufacturer.

Yes, every manufacturer will build a vehicle that will have issues. It boils down to what the manufacturer classifies their customers as. Most customers that like new vehicles are like me. All I want is a vehicle that will give me 5-7 years of good service, then I trade it in on another. I am past the age of buying a used vehicle with over 100k miles that might last 2-3 years, costing me more and more money to keep going. So, in my case, in the long run, it is cheaper for me to buy a new or newer vehicle. (PS. I have to buy the wife a new one too, and yes, she happens to like GM also... :) )

 

Sorry for the blah, blah, blah... but this is all in my opinion.

I have a 2020 Denali with the same axle code and it’s build date is March 2020. I guess we will see how it holds up. It has the play I have seen in the videos. I am at 500 miles and it is silent.

Mine started at 4000. I was silent too.....

Concerns are well documented.  Start shipping out SU5 replacement units with a build sheet addendum.

I agree, the solution above (bshort) is the only solution that will make me comfortable/trust this truck. Knowing that I have a known and well documented failure that is waiting to surface is just as bad as having it already surfaced. The fix is a part swap to the axle without the manufacturing defect until a tooling/casting change can be done to the SU4. I have never seen so much play in a front CV axle to differential. I can only imagine with centrifugal force the damage it will do over time rattling around in the differential/ axle housing.

 

Aleigha W. please help with moving this issue forward for us. There are 62 pages of customer issues. I have spent a lot of money as has everyone here on a truck we want to trust and depend on.

Aleigha this has been an on going thing for quite some time. Kind of disappointing that it took this long for involvement. Many of us here have wasted days worth of time, taking off work, missing kids game, you get the point. Myself, as well as many others had multiple repairs and even front axle/diff replacements and still not fixed. Like the last two posts mentioned. The su5 seems to be the fix. I’ve been told by gm reps to just trade it in and take a loss. It amazes me the nerve. I worked hard to afford this truck.

Reached out and was referred somewhere else, as supposedly being in Ca made a difference.  The Ca rep called and was absolutely useless.  Figured I was wasting my time.

I have the SU5 in my 2020 RST and the chirping started at 15,000 miles.

    • So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.
    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
