  1. I believe he’s talking about keyless entry, where you leave the ‘key’ in your pocket—not where you press the unlock button twice on an older-style remote keyfob.
  2. How about installing some of those automatic folding side steps, like those from AMP Research?
  3. If you’re already having serious doubts and don’t even know what AFM is, I respectfully suggest running for your life; far far away from a ‘19 or ‘20 GM truck. DOD/AFM/DFM/whatever-they’re-gonna-call-it-next-year is GM’s attempt to meet the government fuel economy standards. In the last 2 generations of GM light trucks, AFM turned a V-8 engine into a 4-cylinder under light throttle applications, supposedly to save 7% on fuel mileage. All it really accomplished was a jerking sensation when it kicked in and out, rougher shifting, and a bad exhaust note. It was also widely known for excessive oil usage and other mechanical problems. GM hasn’t gotten the bugs worked out of the system (since 2005!) and most of the dealers don’t have a clue how to fix it, so they just sandbag you until your truck is off of warranty, then either try to get you into a new truck, or finally offer to tear into it, but for a few thousand of your hard-earned dollars, throwing parts at it in a vain attempt at a permanent fix. There are people on this website who have had their engine rebuilt with new AFM lifters, only to have those parts fail, too. They keep changing the name, but no matter what they call it, it’s an over-complicated, poorly-engineered system built with parts from the lowest bidder, and assembled with indifferent tolerances. In an effort to mask the AFM problems on the trucks, GM has increased the oil capacity to 8 quarts, mandated the use of Dexos-rated synthetic motor oil, and decreased the oil change interval back to 5000 miles, and yet many, many problems persist. The latest version of DFM shuts all the way down to 2-cylinders when it feels like it. It can run on 2-3-4-5-6-7-8 cylinders at any given time. So some cylinders can get more wear than others. There is no way to turn it off. This from a company that seemingly has forgotten how to glue a back window these new-model trucks. And the service techs that couldn’t pass high school don’t have a clue how to fix these complicated new systems. GM keeps making problematic systems even more complicated!
  4. You said you only drive this vehicle once a week. Certain tires get a little "flat-spotted" after sitting in the same parked position, to where you have to get some heat in the tires (few miles of highway driving) for the small vibration(s) to go away. I have heard of that problem with BfGoodrich and Bridgestone tires, but not Michelins. If you go on an extended trip, does the vibration go away, or is it always there above 60mph? If everything else is the same (same suspension, shocks/struts, driveshaft, wheels, alignment in spec, etc.) and the vibration doesn't quit after a few miles, then of course, it must be a problem with one or more of your new tires. Chances are you have one or more of your new tires a little out of spec. Find a 3rd dealer, one with a road-force balancing machine (that presses a roller against the tire while balancing), as I wouldn't trust a modern tire dealer that didn't have that equipment. Have them put their best balancing tech on it. It is a fine art to get rid of some vibrations. Ideally they'll spin the wheels first to identify if you have a wheel problem, then they'll install the tires and road-force balance them, and maybe even have to break the bead, rotate the tire on the wheel, and remount it and balance again. It can be a painstaking process (that may cost you some labor time), but can work miracles or identify if you've got a tire that needs to be replaced under warranty.
  5. If it does it especially on cold starts when it is damp out, chances are it's a bad idler pulley or bad belt tensioner. If it's not that, it could be a bad lifter turned sideways in it's bore, scarring the cam as it turns, or an engine bearing.
  6. Is the truck totally stock? How many miles on it? Do you run flex fuel? Engine air filter need changed? I've been told the fuel filter on these is a sleeve-type inside the fuel tank and as such, is not user-servicable. Run a few tanks of a Top Tier brand premium fuel with Chevron Techron Fuel System (not Fuel Injection) cleaner through it. Some of these trucks, even through they are rated for regular fuel, run better on mid-grade or premium gas. If that doesn't fix it, take it to a dealer. If you try to clean the throttle body yourself, you'll probably have to have a dealer use their scantool to recalibrate its position. Some trucks get the spark plugs fouled by the AFM oil usage problems, and this can lead to misfiring cylinders, but that usually is accompanied by a check engine light. If you have that, a dealer can scan for the trouble code(s).
  7. I've had a few, but then again, too few to mention. Oh, I'm sorry, you were talking about new trucks.
  8. You gotta lotta free time and like to argue. So YOU provide US the numbers of all of the 2005-2020 AFM vehicles that haven't had any problems. We'll wait. . . . . . PS There are a lot more AFM problems than just failed lifters.
  9. You spent a month in Silao and hated it. And you love to stir the pot. Thanks for openingly admitting your bias so we can all see where you're coming from! Why don't you use some of your apparently ample free time to learn how to use search functions? In about 2 minutes, I found the following on this website and on Youtube: Nope, no automation at all anywhere to be seen, nor any quality control functions, either. Those welds and some other components and assemblies appeared all by themselves! NOT! Nice, modern plant. Employees did not even appear to be riding donkeys to work like you're trying to imply, UAW troll!
  10. No, no proof whatsover, if you discount things like a 55-page ongoing thread of AFM problems on this very website and GM service managers that say "There are 2 types of AFM vehicles: those that already have AFM problems and those that will have AFM problems." Google 'GM AFM problems' and see how many pages of items you find. Just because you personally may have been lucky so far, or are too numb to notice if you've had any problems, sticking your head in the sand doesn't mean it isn't happening!
  11. This horse has already been beat to death on here, starting with the GMT900s (2007-2013) models. Not one iota of difference, except for political or racial bias on the part of certain observers. The "locally sourced parts" line is bull. Just like the "there's no automation in the Silao factory" line is bull. Go watch the YouTube videos of the Silao plant and tell me there is no automation. You make it sound like GM runs out to Jose's auto parts or the pick-a--part salvage yard down there when they need something. You can get a vehicle with a rattle or a leak built anywhere in the world. Sometimes, it's the luck of the draw. If you go down to Silao, it is a modern city with a modern airport and a big modern industrial area where there are many new plants where they make the axles and the other parts, just like they do up here. Everything is GM sourced and inspected. (Ford, FIAT, and other companies are doing the same thing.) Those are excellent jobs down there, so they get to pick from the best workers. People are waiting in line to work there. Compare that to the current UAW worker mood up here in America--one would have to question the quality of their work when there are so many reports saying the majority of the workers feel like they got screwed by both GM AND their union during the last contract negotiations/strike. I'm as patriotic as the next guy, no--make that more patriotic. I wish everything for sale in America was built here. But that being said, having Mexican-built vehicles in our fleet, I'd have to say that the ones from Silao are as good or better than the "American" ones. The main problems in the Silao vehicles have been with the AFM-equipped engines and various transmission problems, and most of those components were built in America, shipped to Silao, and installed there, so that's not a Silao problem, that's a GM problem.
  12. GM has a knack of having the same overall diameter on their tire/wheel offerings, whether the wheels are 17, 18, or 20 inches. You are worried about the wheel size, acting like the overall diameter of what's turning is just the wheel, but if the overall diameter of the tire on the wheel is the same size, then the effective rear end ratio is the same, no matter what the wheel size is. To know for sure, you'd have to calculate the OD on all of the wheel/tire combinations offered. Also, keep in mind that for aftermarket tires, tires of the same size designation can differ an inch or so in height, just because some of the tire manufacturers like to act like they're big rubber, but in reality they're saving a few $ in manufacturing costs.
  13. I've been told there is no user-serviceable fuel filter on those trucks. The filter is a strainer-sleeve type inside the fuel tank with the fuel pump and fuel gage float.
