  1. It could be that it happens but the majority of this issue seems to be isolated to the SU4 axle. GM even calls out only that axle on the PIP document. Not saying it can’t happen to the other but the reporting from everyone who has the issue overwhelmingly points to the SU4. Just curious if the SU5 axle is only for the single speed transfer case. Most of the issues seem to be either LT or RST. Anybody with the single speed case have this issue? Sent from my iPhone using Tapatalk Pro
  2. I had the same issue but there were more codes with it that showed it was the brake controller staying on after shutting off the truck and it detected wheel movement. When it happens are you parked on an incline any time? There is a software update for it that and it solved my issues. It happened to me with 40 miles on the truck. After the update haven’t had any more lights. Sent from my iPhone using Tapatalk Pro
  3. I'm eyeing those currently. That's exactly what I want to do with black emblems for the tail gate as well.
  4. It’s tied to the build codes that are on the door. I think those are related to the vin number. So if you took your truck to another dealer that didn’t know they replaced your axle with another and they pull your vin from the system it’s going to show the old Axle based off their cross referencing the build codes. It wouldn’t change your VIN but the link your build codes would be off and they wouldn’t know what parts to use. GM will send your the build sheet for any gm vehicle if you ask them and it will pull all the options based on your VIN. So the trucks with the problems are SU4 build codes. That’s what will show up in the system. I don’t think they have a way or want to change the build codes on a vehicle because of that. Sent from my iPhone using Tapatalk Pro
  5. I think if you look up the SU5 Axles don't have this issue, only the SU4s. I've been doing some research and trying to find out which models have the SU4s or if it just depends on where the truck is made. Mine was built in Indiana. If you go look at them and scan the barcode on the B pillar you can see the build code. I'm going to make sure when I get rid of this one that it doesn't have the SU4 axle in the new one.
  6. So got the truck back yesterday and didn't get to drive it much. Took it for a longish drive tonight after dinner and it's back. Made it 40ish miles. It's not nearly as loud at lower speed, but at 40+ it's clear it's back. Already left angry voice mail with my GM Customer Service Rep. Only thing I am no sure is if they did the full repair in the PIP (not that I think it will work), because the O-ring is missing from the parts installed list. Going to confirm with the dealer tomorrow to make sure they did it. Disappointed but not surprised based on the documented history here.
  7. Just dropped it off at the dealership this morning. Supposed to be done today. Probably won't be able to put enough miles on it today to see if it is fixed but will try to do so tomorrow. The weather is also supposed to be warmer tomorrow which usually helps bring it out. Will report back with what happens.
  8. Where did you find a diagram? Been curious and haven’t found one. Thanks for the info. Sent from my iPhone using Tapatalk Pro
  9. The only question I would have is why does the other axle not have this problem? Did they make them different for each company manufacturing them? Seems the SU5 axles made by GM are fine. Would love to have an answer on this. Sent from my iPhone using Tapatalk Pro
  10. Any update on your repair? Mine goes in this coming Tuesday.
  11. It doesn’t inspire confidence but it’s the first thing they have done since just keep replacing the axle with another one that is prone to the problem. I was told they changed the axle. I tried to get a part revision history from a few part suppliers but they weren’t able to tell me anything. So if this is coupled with a change in the stub shaft and is just an insurance policy.. maybe not so crazy. If it’s just this and nothing else.. yeah it’s crazy and why I am nervous this doesn’t fix it. Some have said it doesn’t in this thread and some have said it did work but for how long is the unknown. I just can’t believe they screwed this up so bad and can’t fix it. Its not like this is the first 4wd system they ever built. And only seems to be from one supplier so it should be easy from a quality perspective to figure out what the hell is going on. Get one of the good ones and one of the many buy backs and play the “what’s different game”. Sent from my iPhone using Tapatalk Pro
  12. I just got word that my parts came in today and I am scheduled for the repair on the 9/29. It was about 2 weeks from ordering to the call today. I will say I don’t know if my call to Chevy customer support made any difference in the part delivery timing. The rep said they were expediting. Will report back after Tuesday how it goes.

  13. I'm waiting on parts as well. Apparently the axle is on back order. After driving it last weekend I got mad and called GM Customer Service. Told them the issues I had experienced in the 900 miles of owning the truck. They passed me off to a senior advisor who finally called me today after 6 days. I politely but firmly let them have it. I told them the fact that they are still pushing trucks to the lots out of factories when customers are waiting on parts to fix their vehicles is bullshit. Also told them I'm aware of buy backs on trucks because of this issue and that I am documenting everything, and I'm well versed in my state's law and this is their first attempt to repair. I am supposed to be getting updates every other day on the parts tracking status. I'm sure as others have dealt with this is a lot of hot air, but right now it's the only thing I can do to keep pressure on them. Good luck!
  14. If you watch the instant fuel mpg you can usually tell when it kicks in, but as others have mentioned it's not just a v4 or v8 mode anymore.
  15. That’s all too familiar. What all have they replaced in this process? Sent from my iPhone using Tapatalk Pro
