good to know about the CEL on Aero circuit. (Curious how you knew that?). I called Putco and they are sending a relay to prevent 12V feedback into the circuit. At present, everything is disconnected and no logic lock issues. But I’m getting weird starts, such as hiccups or slightly longer turn overs. I even had a moment where I had just jumped in the truck and started it and the locks started rapidly locking and unlocking like a they were in full auto. Haven’t tested the battery load, however it is a new battery this year. Upgraded to an Odyssey 94R AGM for CCA and higher reserve capacity.

Update 1: - Speaking with tech, he suggests the truck is going into a “logic lock” due to an “unhappy module”. Disconnecting and grounding the electrical appears to be resetting the module. - I will need to produce the fault and tow it in with the error active for him to try and determine which module is causing the issue.

2020 AT4 46,000 km Bumper-Bumper ended in April 2023. - Engine cranks very fast. - battery at 12.5V+. - Fuelled up. - many codes pop up after trying to crank, but the initial codes can be P062b, P0690, P16B3, P16BF. - occurs intermittently. I can be driving for days or weeks and then suddenly at my destination when I hop back in, no starting. - there is sometimes a bit of a lead up where the cranking takes slightly longer than usual. - when I disconnect the battery and ground the negative for 30 seconds, the truck will start again. - issue has occurred when mods were disconnected too. Electrical Mods: - Putco Freedom Blade with plug harness adapter into tail lights. ACC voltage supplied from aero shutter fuse. - clearance LEDs tapped into marker light (left) fuse. - wireless trailer cam tapped into marker lights (right) fuse. Dealer 1: - diagnose & taped up ECM harness (noticeable wear to wires): ~$500 Dealer 2: - replaced power train harness: ~$500 - dealer 2 suggested replacing lower fuse box as next step. Has anybody had any similar issues? Any advice? Thanks!

My favourite has been the Xtang Xceed. - Seamless matte black vinyl covering Aluminum panels. - low profile & Looks great. - 500lbs distributed load on top. - Water tight. - secure, locks with gate. - one hand open. - it’s tri-fold & can secure closed, 2/3 open, and fully open. - full tailgate operation even when covered. I’m moving to a bed rack though, so I’m actually selling mine to make room for something else. But hands down my favourite so far. Retrax XR is next, but so so much more expensive!

I've been thinking about doing this too. I have molle on the seat backs for my gear, kid stuff, and First aid. I wanted to make something to secure other emergency supplies in the back like the Safe Jack kit. Found some already had a great idea. I have the Undercover Swing Case on one side. Thinking of using this for the other side. Not sure about the front, I might redo my bed from Xceed tonneau & Putco Rails to a Retrax XR (with T-slots) and top it with a Leitner Rack system. More storage!

Sorry for the delay. Didn't get a notification. They replaced the CV axles under warranty. The service guy tried to tell me, but noticing the lift kit, that my axles were "way out of spec". I told him to try again and take a look, with the BDS lift & diff drop, my axles are closer to factory spec than with the added AT4 2" factory lift. They offered a one time replacement, but the installers said they would stand by it and challenge the dealer should they give me grief about it again. Does the rough country include a drop to re-align the axles?

That’s right, the BDS was a full kit with drop. The CV angles were very good. This kit: https://bds-suspension.com/product?kid=1805H I suppose my next question, is what is the fix for the leaking axle, and how would it have happened? Install issue? Bc then the shop should redo it properly. If this is a failure issue, then maybe* dealer will look at under warranty. BDS was adamant that their mod doesn’t break warranty issues for parts not replaced. (Dealer also uses this shop for all their mod work too - they go out of house for mods).

I had initially driven in 4 auto for the first few thousand km. But had gone to 2WD since (currently at 22000km) because of the issues that have been noted in general and specifically with lift kits. Would the leaks be an issue from the lift kit install? I had chosen the BDS kit because I wanted a neutral angle on the axles vs other cheaper spacer only designs.

4” BDS lift on 2” 2020 AT4 Custom shop installed. I recently started having a whirring/whine sound when starting off slowly and maintaining a slow crawl. Almost sounds like riding the clutch with a worn throw out bearing. Now since winter I’ve been getting groaning and creaking during the same process but pronounced over uneven surfaces. I suspected the suspension bolts needed tightening. Going underneath to peek, I found that the front CV axle boots appear to be leaking & spraying grease. Maybe they are making the sounds as they start and as they flex. No tears, seems to be leaking at the seam. Same on both sides. What is going on here? Is this the culprit? thanks!

Any of you who installed go through winters? Curious how this holds up with freeze / thaw - water getting under and freezing. Feel like this might just pop off

It’s by Black Horse Offroad - Armour Bull Bar. Unfortunately at the time, they sold it as compatible with 2019-2020 Sierra, but it certainly was not, at least not for the new body type. Electrical was not plug in play. Also probably due to my AT4 having vertical tow hooks. But! As I do, I cut, ground out, repainted, trimmed plastic, spliced, soldered etc to get it to fit and to relocate the forward parking sensors to the bar. Sent from my iPhone using Tapatalk Pro
