2020 Chevrolet 1500 Silverado, 28k miles purchased last November and my horn has gone out again. This will be the third horn to be replaced. I'm not in a city and really don't use my horn that much except sometimes when I want to confirm I've locked the doors and hit the remote lock button twice. To clarify, its the low note that goes out, so what is left is a horn that isn't even worthy of coming from a Yugo.

Are you suggesting that some of these trucks get better gas mileage then others? When I read your post it vaguely rang a bell that this might be the case.

Duh! What a typo. If you need me I will be under my truck…since it’s like a rock.

sorry I may not have been clear - my truck is a 5.3 gasser not the 3.0 diesel. If I drive like there is an egg under my foot and don’t let the engine go over 1,500 rpm I can eek out barely 14 mpg around town. Not much fun driving this way. I understand the cab is essentially the same between the 1500 and 2500 but the padding in the 2020 seems half of my 2015 gmc. If I went with a 2500 I’d probably go down to a 2018 or 2019.

So I bought a 2020 Chevrolet Silverado LTZ 5.3 late last November with 23K miles. Its black, crew cab, 4WD and light tan interior. It's all stock and I pretty much bought it as I needed a tax write off and after a two month search for a 3.0 Duramax didn’t pan out. This past March I towed my 25' boat on a 1,100 mile round trip and gas mileage for the trip was 8.2 but I saw as little as 6.3 mpg with a headwind, so I am thinking about trading this one in on a 2500 Duramax. My buddy just bought one and is getting way better mileage unloaded then I have with any of my previous gas motors and interestingly the 2020 is getting way worse mileage around down then my 2015 GMC crew 4x4 even with the auto stop. Around town with the new truck I am luck to see 14 but unloaded and under 70 mpg it does get up around 21-22, but so did my GMC before I put bigger tires on it. Is it worth moving to a 2500 for a once or twice a year long haul? Probably not but the increase in local mpg is what really has me interested. thoughts? Also my wife said the back seats were incredibly uncomfortable, something I thought as well shortly after I purchased the truck.

Dealer just called - bad battery. Thompyt88 - sorry for the thread highjack!

I have tried to get it to come on with every option in the truck turned off, i.e. radio, A/C, seat fans/heaters, lights off, etc. I have an apt with the dealer in ten minutes so they can figure it out. Only 20k miles on this truck but I am the second owner so will see what's up. I will say that I reached out to TRL Automotive who was reference above with their auto stop eliminator and they were VERY quick to respond and helpful. I get the disdain for the auto stop but would like to ensure that there isn't something else going on like a weak battery.

Is there a way to know if an autostop disable harness is installed without pulling all the trim off? I bought a 2020 Chevrolet Silverado and the autostop doesn't work so after seeing this post just curious before I take it to the dealer.

It is a simple box that plugs in between the bulb and harness. Plug and play. Should have come with the bulbs. Contact the seller and see if they will send the modules to you for free. Mine have been flawless for almost five months now.

I just installed a set of the GTR Ultra 2 LED bulbs into my OEM projectors in my 2015 GMC Sierra. install was less then 30 minutes but did need the PWM interface module to make them work. So far, i'm pleased and at least now I can tell that the headlights on and I can see light on the road. They are definitely not as bright as my buddy's 2018 GMC OEM lights FWIW. I still have the HID kit from fastheadlights as well, just never got around to installing them and they have never been out of the box.

When you do it take pics. I’ve had the kit for ten months in my closet and after driving 2500 miles I’m either selling the truck or installing the kit soon. Love my truck but at night it’s down right dangerous. I’m planning on baking them in the oven vs cutting the housing. Takes longer but a cleaning look imo.
