Radio replaced because it keeps blacking out. It’s happening again. Steering column replaced because of loud noise. That’s also happening again. My brakes vibrate and clunk like the abs is kicking in. It’s very strange. Lastly, I’m starting to get this loud noise when my ac is on. Happens randomly but when it does it sounds like a plane is flying over and I could feel it throughout the truck. That just started.

Wow that sucks man!

 

You definitely got a lemon and GM needs to make it right.

Anyone that's had the "fix" done and had to go back, have any updates yet?

 

Mine is in the shop now. I sent the foreman an e-mail asking to see if they could replace my AAM axle for the GM made one, but no response yet.

 

They've had the truck all day yesterday and today and no update yet.

Is there a part number for the GM axle that someone could get off their truck? 

 

I think i have the AAM axle but have to co firm when I get my RPO codes. I crawled under the truck and I see a tag on the axle that says AAHD with part number 84557635. At this point I am assuming AAHD translates somehow to AAM.

 

i grabbed the drivers CV and while I couldn’t get and lateral movement (in and out) I was able to shake it up and down and side to side movement and there is a clicking.

That would be me My BBB arbitration will be on September 12th keep you all posted.

By the way a GM PiP is NOT the same as a TSB. The PIP only tells the service department they are aware of the problem and a fix is pending. A TSB is a bulletin telling Dealers a fix is finalized and in place. So If there is a TSB on this issue who has the number.?

Interesting. I did not know that. Maybe an actual TSB isn't out yet then?

Ok so got an update. The SA at the dealership said that GM knows of the “new fix” and that the part is completely out of stock. They are making new ones and can take up to a month for my dealer to get it in. He ordered for me but said they are sure this will fix it. I asked if it was the axle and he said he didn’t know because when he put in the order the picture was blank and description lol. 

 

Hopefully this is the fix we’ve all been waiting for. I decided to get my truck back and wait for the part since I’ve only enjoyed it two days. 

Hope this helps you guys.

Do have the part(s) info you could share?

 

i got the RPO codes from my dealer today and sure as luck, I do have the SU4 front. I have a feeling the rattle I have is only the beginning of what most of you all have experienced already. I only have 2600 miles on my truck and it was a 11/2018 production. Everything on the truck has been solid so far except for this axle problem.

 Unfortunately not. I tried but all he said was GM doesn’t have it and won’t for a little while. Haven’t checked my build sheet but I’m sure it’s an SU4.  As soon as they call me that the part is in I’ll let you guys know.   Oddly enough mine was built 06/19 but you’d think with all these issues, they would've fix it moving forward but I guess not.

Thanks for the info. I bring mine truck in next week so can listen to the Noise. I'm hoping they have a fix by the October im planning a 2500 trip and don't want to listen to this annoying jingle for the trip.

Sounds good. Much appreciated.

 

The diversity among production dates just shows that there is a major defect with the way AAM is producing these axles. I only hope that the “fix” is an actual fix this time and not just another patch deal. 

 

Up up until this point, the only real fix would be having the AAM axle swapped for a GM axle. GM doesn’t want to go this route because one, the RPO codes would have to be swapped from SU4 to SU5 (not even sure if this is possible in the system) and two, all production of AAM axles would have to stop and only GM axles used for current production which would be a logistical nightmare.

 

On a side note, I looked up the cost on a replacement AAM front axle, which is probably similar to a GM axle (I don’t have the part number for a GM axle). It’s $1750 msrp and $1080 wholesale through GMpartsdirect and others. If worse came to worse, I’d be buying a new GM axle if this new fix doesn’t work.

Might want to check that date again...11/2019 hasn’t arrived yet.

 

If you want a build sheet with all RPO codes, you can email [email protected] & request the build sheet for your VIN. I did this on a weekday & had a reply in a few hours.

What exactly is the new fix for the noise? Does anyone know? Just read this after picking mine up today from having the latest fix done, which did nothing.

Well...... Not fixed.

 

So I went to go pickup my truck and was told that they ordered the axle but its back-ordered.

 

I was told that they will be replacing it with another AAM made axle because that's all GM will authorize.

 

They are supposed to call me when the axle is in to complete the repair.

 

I was able to get a copy of the bulletin. I will post it here.

 

Thinking of call GM and starting a case with them. See if I can get them to apply the new fix.

 

I have done multiple visits now and getting tired of having to go through this on a brand new vehicle.

    • 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.
