I pick up my truck for the 4th time today from the dealer. This time just like the last time, they did nothing other than put miles on it. Social media team said they would coordinate and get others involved, and apparently went no where. I've wasted 8 hours driving to/from the dealer. Shared a video of the issue that i took on my way to drop it off before attempt #3 that showed all of the issues, and yet they "can't replicate it" so no issue fixed. I was asked a couple times to come in during normal business hours to chauffeur someone around to let it replicate. Not taking time off work to waste even more time than i already have on this issue. For those having this issue, I have reached out to a lemon lawyer after attempt # 3 and they have stated this is a valid claim if you're looking to ditch your truck and be reimbursed. I'm currently in talks with a few dealers about trading my truck in on a F150. Trade in is almost what i paid for it new (before taxes) so another option if others are looking to do similar.

Email: [email protected] I found they were very responsive while my truck was in the dealer the last 3 times...Updated me a few times before the dealer did on a few things, but ultimately my truck is still not fixed and it was left at that.

Got a call today from the dealer to come pick up the truck again (3rd time). Forgot to ask what they did while they had since i last posted until i got there. According to the adviser i spoke to, they drove the truck 100 miles and couldn't replicate the issue. I take the fact they gave it back without any fixes they have given up... Prior to the pick up, i ensured i deleted all vehicles tied to my carplay on my phone and did the latest update that popped up here recently. It did not crash on the ~45 minute drive home, which is positive but think it's just luck. Truck will likely sit until we head west on Saturday for a race so won't get a good long test on it until then. They are supposedly going to be extending my warranty on this particular issue, waiting on the email from GM to say how much it's extended. If it arises again, will be bringing it to another dealership.

Didn't realize that was a judgeable offense... ? I don't like wires hanging all over the place, and didn't want to have to reach up to turn it on and off. I turn it on/off frequently if i'm going thru somewhere that sets it off, get stuck by a car with blind spot mirrors, etc.

Radar detector.

Truck is back at the dealership as of this morning. Volume wasn't working properly with music now. Make an adjustment and there was a huge lag where it would gradually change based on the previous knob turn. Was able to get a video of the issues that i need to send over to them before Monday. With 2500 miles left on my warranty, i'm going to keep giving it to them until it's fixed.

Positive news. They replaced the radio on my truck and i was able to pick it up today. Unlike last time where i only made it 1/2 of the way home, today i was able to make it 2/3 of the way! My volume also goes in and out now as well while on the phone so that was a nice new surprise.

Dropped the truck of Thursday evening and picked it up this afternoon. They did a software update... GM bulletin #20-NA-097. Made it half way home and the screen crapped out and restarted during a carplay phone call. Turned back around and left it for them to re-diagnose next week.

2019 GMC Sierra is doing this as well...This thread gives me a ton of confidence of this being fixed...

Yes. Easy install. About $270 to buy all of the parts. Few threads on here that will give you part #'s and some instructions.

For reference, here is my tire clearance with the RL UCA (Tire specs in above post). Note that the outter lugs on the tire are not offset in the image so clearance is less than shown. I've articulated the suspension pretty well to check for rubbing and haven't caught any marks yet but it is certainly close. I'm convinced on this size tire, it will 100% come down to actual tire selection and not all 285/75/18's will fit without wheel spacers.

No good ones but here you go. 285/75/18 Nitto Ridge Grapplers Stock 18s No wheel spacers Zero Trimming. Zero way to go any wider of a tire without hitting the Ready lift UCAs unless wheel spacers are added, which will probably cause more rubbing issues. Only rubbing as mentioned above (Slight rub going over a bump at full lock) Truck has a 1 to 1.25" rake with the 2" SST.

Stock 18's.

I'm on that size tire but have the 2" SST. Very minor rubbing when turned going over a bump. Normal conditions, nothing.

Just finished installing my upfitter switches today and finished the hardwire of the radar detector. Chose to use the new dash piece as the template and cut it in instead of tearing about everything. A sharp exacto knife makes it a breeze and well worth the time savings. Worse case i figured, I screw it up and then just replace anyhow. The biggest pain was getting the wire fished thru the fire wall, which knowing how to do it now it is a breeze. Coat hanger made it so much easier. I had it all wired in and then no power at the radar detector, switch lit up. Turns out, there are 2 loose blue wires in the new wiring loom...Once i realized this it was an easy fix and quick to wrap up.

Buy online? I just got mine less than 2 weeks ago from GM Parts outlet.

GM Parts outlet. At least from the email they sent, they had to order all of the parts and that caused a week or two delay in shipping. Edit: FYI, if you throw the parts in your cart after creating an account, you'll get some sort of discount. It was minimal. GM Parts outlet was the cheapest on all the parts required that i could find.

You sure? Just received in all of my parts last week, ordered 3 weeks ago.

Do you have an apple watch? We put my wifes on the bicycle app and it matched waze for me.

The AT4/TB should have no better CV angles than a non AT4/TB. The GM AT4/TB kit is a glorified leveling kit at the end of the day they're putting on these trucks so adding additional lift is fairly significant without doing a diff drop and correcting geometry. I would plan on something with new uppers no matter what you choose. The factory "lift" does not include new UCA's so i would assume these are shared across the platform. Here is a 2.5" on a non AT4/TB truck that had a failure recently. It was a crack instead of a ball joint so could be unrelated, but too many UCA issues to not replace when adding any additional height IMO. https://www.facebook.com/groups/AllNewSilveradoSierra/search/?query=upper control arm&epa=SEARCH_BOX

Just took this photo. AT4 w/ 2" SST. Angles aren't bad at all. No worse than my 2011 F150 with a 2.5" which i ran for 150k+ miles that way with no issues. I believe i read that on the new GM's they have a narrower diff so longer Cv's and better angles. I do have minor rubbing with the tires at the moment (AT4 w/ 2" SST, 285/75/18 Ridge Grapplers on Stock 18's). Very minimal and only when the suspension is minimally articulated going over a bump with the tires turned. Doubt i'll even mess with it. The one thing i need to check again is the UCA's. It looks like i may have a minor rub mark. I need to clean them off and then go play around at different steering angles and inclines and check to see if it grazes or not.

Get new upper control arms whatever kit you buy since you'll be at 3.5" with your TB. Not worth the risk to end up with a broken upper on these trucks.

You want me to go off pavement ? Honestly haven't checked yet. Next time I go out into COVID world, I'll see if I can find a spot to check. Most "off-roading" I do is the dirt/gravel roads to get to the trail head to ride our dirt bikes so not a ton of articulation this truck will see. @Alex Kemple Have your guys checked when the truck is on the lift for clearance in the past?

From my understanding, the 18" AT4 and TB wheels have the same specs. I could be wrong so please double check. Can't find the link another user had posted for all the stock wheel specs. Here is a shot of the clearance between the tire and UCA with the 285/75/18 Ridge Grapplers. It looks a little worse than it really is, somewhere around 1/2" clearance with the tires straight.
