2019 Tahoe Remote/FOB Issues

Identical issue here with my 2018 Suburban.  Took around 15 visits to the dealer for them to finally solve the issue by replacing the antenna amplifier.  Shortly after we had issues with the engine mounts and a leaking rear air shock.  Had them replace the vehicle under the Lemon Law and opted for the same vehicle just the 2019 model.  Guess what?  Same exact key fob issue with this one as well.  At least this time they knew what to do.  They replaced the antenna amplifier last year and all was good...until yesterday.  Got in the car and it wouldn't start...keyfob not found message on dash.  Also passive locks wound't work again and remote range was about 20 feet from the vehicle (line of site).  Called up dealer and made another appointment to have it replaced yet again...I can't imagine my luck is that bad and that many others out there aren't experiencing issues like this.  It has to be more wide spread.  I sure hope they figure out what is actually causing this.  I ordered the BlueDriver and am going to give that a shot too just in case.  At least I found others that are having the same issue this time.  Two years ago when we were first experiencing this issue I couldn't find anything online regarding others having similar issues.

HELLO, BOYS! Yes, same issue with my 2019 tahoe! My remote on 2015 tahoe worked from about 1/2 the mile... not kidding. I have a theory though, GM just trying to push you to buy theirs servi

I have the same issue with a 2019 Suburban I just bought. Took it to the dealer around the corner from my office 1st thing this AM out of convenience. I showed them the bulletin, PIT5665.

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 tha

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.

Mine is doing it more and more now. Do you think any programming needs to be done once the amplifier is replaced? I was thinking of swapping the part out myself.. Its only about 25 bucks. Just waste too much time going to the dealer

Well I changed out the amplifier and it works for now. Let’s see how long it lasts. Cheap part made in China. Very easy job.

Our 2016 Suburban is doing the same thing.  How hard is it to change out the amplifier and where is it located.  Do you have a part number?

Easy to do. 20 min. Below is the part I used. They make 2 different parts with different frequencies depending on your RPO code. Got mine from rockauto.

Thanks Bob!

You might not have to take off the pillar panel behind the back door. The burb is longer and should have enough pull down room of the headliner.

Thanks, makes sense.  I'll have to see what part number I need and go from there. :)

I've a 2017 Tahoe and have this same issue with just one of my two remotes. Tried replacing batteries etc but nothing seems to help.

More than likely it’s the amplifier.

Part is 20 bucks from rock auto. I was under warranty too but I hate to have anyone work on it. I would have greasy hand prints all over my headliner. I just know it. I am ver particular about my cars.

Make sure you get the right one for your vehicle. They make 2 different frequencies. I would suggest looking at the one in your vehicle. This way there is no issue
