What I don’t get is why the dealer don’t acknowledge these codes and clear them. They have the correct tools that are designed for these vehicles and I can find it with a $99 tool, clear them and my problem is solved. Crazy

Again.. the dealership I brought mine to today said "no problem found" and then I got a NASTY phone call from the service manager in response to my email to the service writer saying it was not fixed and that there most certainly is a problem. If they had scanned and found codes they should have said so on the paperwork.

I have a 2019 GMC Yukon XL Denali, an $82k vehicle.  I bought it new and have had it one year.  It has passive unlock and push button start. I’m here looking for help after dealing with the remote not working and the remote not being detected, basically all the issues reported on this thread are exactly what I am experiencing/have been experiencing.

 

Trips to the dealership have all resulted in them ‘not able to reproduce’ the failure, and ’system passses all checks’.  I am so frustrated - I’m nearly ready to speak with an attorney.

 

I reject the suggestion that I must use their app on my iPhone.  The vehicle came with key fobs.  Why don’t they work?

UPDATE:

 

With the knowledge I gained from this forum, I tried the local GMC dealership one more time.  This time, and with a different employee, they acknowledged a reported problem and advised that GM engineers are investigating, and they offered to replace the AMPLIFIER. The employee said another customer with the same vehicle had all the problems I reported and replacing the amplifier solved his issues.
 

A new amplifier was installed in my Yukon yesterday. No problems since and a much improved range. I’ll update the group if any issues return.

A new amplifier also cured my problem, all is well now... I found the bulletin on-line and informed my service manager about it.  Not sure they'd have found it on their own.... But Chev authorized the replacement and it's fixed.... 

 

On my first long excursion with the '19 Tahoe, pulling a 3200# trailer, about 320# tongue weight, the rear shock compressor seems to run almost constantly, which I'd interpret as a leaky shock?????

Hey guys, It looks like this is an on going problem, I'm having the same issue with my 2019 tahoe Premier  Sometimes I have to be only 10 feet away from the car for the remote to work. I trade in a 2016 Tahoe  And I never had any problems with it, I mean the remote will work from literally a 1/2 mile away,  I think is unfair to have to deal with this problem in a $70,000 truck.

 And I think I'll have to agree with Artemiy Sevostyanov on the theory that GM  Is trying to force vehicle owners on to buying services like internet or remote commands on the app that used to be free on my previous 2016 tahoe, 

I really hope someone finds a solution to this problem....

Update #2

 

Problems have returned: key fobs not detected, passive entry intermittent, key fob range quite poor.

This link was perfect.  I had the same issues with my 2018 Suburban and after bringing this bulletin to the dealer they replaced under warranty and now the range is awesome.   It’s just surprising that the dealers aren’t aware of it as I had my vehicle in once before to get fixed.  Thanks for sharing the link.   Enjoying tje ability to remote start from 50 yards away +.

I have a 2019 Tahoe bought in June & my key fob will not lock or unlock the doors (much less remote start) unless im within like 30 ft of my vehicle. It does seem like it’s getting worse but I’m curious how does the battery die within (not even) 1 year? So annoying. I haven’t tried changing out the battery yet but was trying to see if it was a common issue & if needed to take it to the dealership or not!

i have a 2018 suburban premier that i bought after it'd been in a wreck so i can't file any warrant claims.  i feel that my issue is the antenna amp.  i'm just wondering where this is located and if i can replace it myself?  they dont' seem to be too spendy, roughly $30-40 online ($65 at dealer).  it looks fairly plug and play but i dont' know if there's anything else the dealer has to do to make it work.  any help on this would be great before i spend $80 on a diag at the local chevy shop.

Save your money. I only got one good week out of the new RF amplifier the dealership installed.

so you are thinking that they are faulty or something is causing them to go bad further upstream?  ie, we still don't have a solution to this issue.

 

thanks for the prompt reply

Clear all your codes. U, B,C. It worked for me when I had issues. Been working fine since.

I found the cheap OBD readers don’t get codes other than p codes. I used the blue driver one. It gives option of a quick scan or a deep scan which will get all the codes. I really like the blue driver. They are always updating it too

      Hey all, 
      I have looked and looked for more clear instructions on how to program a second key fob for my 2020 Silverado (dealership lost 2nd set). I live 8 hours from where I bought the truck and the dealership I bought it from would need the truck to program it. I am trying to do it myself. I have followed this guide but still no luck. The youtube video that is out for it is if you are programming a key fob without already having one programmed. It wasn't much help for me. Any GM Mechanics have a quick write up they can copy and paste would be appreciated. 
       
      These are the two things that haven't been enough help for me.

      Hey all! I am new here, but have a very frustrating item on our new (to us) 2018 GMC Yukon XL Denali. The buttons on the exterior door handles that lock and unlock are driving me crazy. I think these are called passive entry buttons (not sure on the actual name). Both buttons on the passenger side work just fine, but neither of the ones on driver side work. They depress, but nothing happens. I have checked all fuses that may be associated with this system and they are good. I have went thru settings on infotainment system with no luck either. Please tell me someone else has seen this problem and can help me out! Thank you so much!

      Yesterday on GM Authority (they had a story about vehicle-mounted keyless entry key pads (not fobs) http://gmauthority.com/blog/2019/10/keyless-entry-keypad-offered-as-gm-accessory-for-buick-chevy-and-gmc/.  After a little more research and reading I have found that you can buy it as a kit and have the dealer or someone else install it.  So I have a couple of questions.
      1. Can I get it for my 2014 Silverado LT?
      2. Does the installer need to be a dealership technician?
      3. What is the general quality review of the new system?
       
      Thanks!

      I have a 2019 Chevy Silverado 1500 and my key fob only has the lock/unlock, and the panic button on it. I saw that the official Chevy accessories page has the key fobs with remote start, tail gate unlock on them as well. If I get one, will I be able to have the dealership program it on my current truck so I can have remote start or is this only for replacement for owners that already have the same key fob?

      My Ford F-150 didn't have keyless entry so I kept my keys in during one of my extended overseas trips, using the keypad to get in and my keys always safe. I could never stand the thought of losing my keys 6,000 miles away and having no way to get in my truck and I wouldn't be able to get in my house! I learned it the hard way a long time ago, never again.
       
      I didn't know my Chevrolet came with keyless but it was attached to a fantastic deal I couldn't refuse so I had a dilemma. I could use my phone to unlock my truck so I didn't really need the keypad my Ford had, but I just may install one for $250 at the dealership anyway. That's just in case I lose my phone whilst overseas.
       
      Unfortunately, keeping the keyless fob around the new Silverado will cause battery drainage as the module will be kept active when the keys are detectable. My truck didn't lock when I was at the back of my truck. As one member said, the Hitch Safe wouldn't be good enough and he's right so it was no longer an option. One here suggested wrapping it in aluminum foil and I tried that. It worked very well and realized my Progresso soup can had thicker aluminum so I tried it with the smooth-edge can opener and, voila!
       
      I am very pleased to report my truck did not unlock when I held it inches away from the door. To think I was going to spend $19.99 for a can of Coca-Cola with a secret compartment!

      Now, my question is: if I used my phone to unlock the truck from a distance... how long would the battery last before it dies? Can it do a month?
