On 2017 Sierra.  Really weird it’s always been a bit tight to open I lubed a couple of days ago and now won’t unlock with FOB or with key.  Any ideas?  If not looks like I’ll use my extended warranty for the first time.  

 

Thanks.

Are you sure it's locked?  It may be the actuator rods.  Pull the panel an the inside of the tailgate and make sure both the left and the right rods are connected to the center handle mechanism.  I had one side pop off on a road trip earlier this year.  Simple fix, but aggravating and I had no tools with me, I so I had to stop at a dealer before I could continue my trip.

Thanks Mike I’m not sure how to pull that panel.  Are taking about where the handle is?

Mine likes to stick.  If I haven't had the tailgate down for a while, I have to lock and unlock the lock several times while thumping around on the tailgate before the latch will catch and allow you to open the tailgate.

No, the large panel inside the tailgate, facing into the bed.  There are a bunch of goes head screws.

Mine acts the same way.  Just went and messed with it and it unlocked twice manually with the key but won’t from the fob.  Weird

Quick update for everyone.  I bought my truck used.  It originated in Canada.  What I noticed when I got it it, was a layering of light sandy dust on the under carriage, lower engine parts and other areas.  This obviously was the sandy salt that they coat roads with up there in the winter.  When I got the tailgate panel off, the entire assembly was coated in this dust.  Bottle of air wouldn't even help.  I had to take a hose and spray off the entire assembly.  Waiting for it to dry and will lubricate with lithium grease.

 

Thanks for all who replied, this saved me a trip to the dealer as all the rods etc are fine.

      Tire psi

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.
