HondaHawkGT replied to Jimbo20's topic in 2019 Silverado & Sierra TroubleshootingFord and Ram aren't having any more luck with stuff like engines, transmissions, or overall build quality. GM, Ford, and Ram are all changing platforms and major components often enough that all 3 have issues to address. Ford's 2.7 Ecoboost had a few major design issues and instead of fixing them, they just moved on to the 2nd gen 2.7 where they changed a ton of stuff and added a lot of new tech. None of the changes were directly targeted to fix 1st gen issues. Ram's 8-speed trans was redesigned for 2019 and as a result of those changes, the trans now has all kinds of new issues that FCA needs to fix. You're experiencing the downside of buying the first model year of a new truck that's based on a new platform, with a new fuel system and a 10-speed transmission that GM is using in a truck for the first time. Some guys will have problems.
Sure, if you ORDER it. It's very rare to find one with 3.73's on the dealer's lot equipped the way you want it. And some of their engine options will not allow you to combine it with certain gear ratios including 3.73's. The point being, sure you can get factory 3.73's, but in most cases you won't be getting anywhere near as much in incentives for a truck you order. So where you could get a whopping $15k off an XLT F-150 with whatever gear ratio it came with on a dealer lot, you might end up losing thousands in incentives just by custom ordering that XLT with 3.73's in place of the typical 3.31's or 3.55's.
As soon as you have the classic signs of a stuck AFM lifter you should pull over and shut it down as soon as is safe to do so. The guys that end up with major damage are the ones that tried to limp the truck home. Better yet, just use a tuner and disable AFM. The fuel savings is so insignificant for most of us that it isn't worth it.
The gas is argon. GM demonstrated exactly why aluminum is very unforgiving and prone to tearing/cracks. Ford fans are VERY eager to point out that commercial airliners and many dump truck beds are made of aluminum because the material is so strong. Aluminum does indeed have an excellent strength to weight ratio. The problem is that the whole reason Ford wanted to use aluminum in the first place was to REDUCE THAT WEIGHT. Once Ford thinned out the aluminum to save weight, the panels began to be more challenging to produce and the beds were far more prone to cracking and tearing. There's no such thing as a free meal and Ford prioritized weight savings over strength. I work with guys with 2018 and 2019 F-150's. The wavy body panels are still there. The inconsistent body panel gaps and misaligned doors are still there. The bed sides are still thin and cheap feeling. I'm glad GM stuck with a steel bed on the new trucks in case I decide to trade up some day. I would rather have to spray my bed down in fluid film to keep away rust than to have to worry about a bottle jack sliding around causing the riveted seams to split apart like I would with an F-150's aluminum bed.
This is the first year GM is using ZF's new Integrated Brake Control unit. The brakes in your truck aren't boosted by a mechanical vacuum pump like the previous K2 trucks were. There will be a bug or two related to the new ZF IBC setup I'm sure. It sucks man. Automakers are rushing a lot of new tech into their vehicles every year and we all pay the price for wanting the latest and greatest stuff. https://www.wardsauto.com/technology/gm-plans-vacuum-free-braking-next-gen-trucks-sources-say
GM's full-size trucks tend to have a firm ride. The 2019 ride slightly better than the previous K2 trucks, but they still have a suspension tuning meant to give the truck enough capability. Generally speaker the softer the ride, the less payload/towing capacity. Z71's will have a firmer, rougher ride due to the twin-tube shocks.
I didn't have to drill my spindles or cut my droop stops off. Granted when I installed mine the instructions weren't yet updated for the 2014-18 trucks, so my ball joints are bolted to the underside of the control arms instead of inserting them down through from the top. They've been that way for a few years now without a problem.
The older Vortec engines used an iron block. That makes a big difference when it comes to noise. This engine uses an aluminum block that tends to transmit noise and makes everything more audible. The reason your 2008 Cadillac 3.6 DI engine doesn't make any noise is because GM engineers used a LOT of noise insulation on the engine. The engine in these trucks have nothing. These engines are just as noisey as Ford's Ecoboost 3.5/2.7 and 5.0 Coyote. Even Toyota's DI engines sound like sewing machines.
I get 22 MPG at 60 MPH with cruise on and minimal hills. The best I've ever done over a 400 mile average is 23 MPG. Typically 20-21 MPG at 65 to 70 MPH average with slight elevation changes. The main reason I do so well is thanks to these god forsaken 3.08 gears.
1.) I KNOW that the 3.0 is based on the Lion 3.0. Even Ford has stated that the engine has been heavily redesigned to meet US emissions. And when Ford tries to design engines, the results are usually pretty terrible. 2) The 6.7 Scorpion is alright but I wouldn't call it awesome. It's easy for an engine to look good when the 6.0 and 6.4 it replaced were such garbage. It's a good thing the Austrians designed the engine for Ford or it wouldn't have had a chance. 3.) Funny there are a lot of guys with GM K2 trucks that never have a vibration issue. Some guys do, but the same can be said for the F-150. The 12th gen F-150 had high-speed vibration issues. The 2015-18 F-150 has the same high-speed vibration issue. Just like the GM K2's, some are affected and others are not. That was my point. Just because you trade one brand for another doesn't guarantee you won't have a vibration. 4) The guy in the video could take it to a dealer and have the dash replaced. It would be a waste of time but he could do it. A LOT of guys had their F-150 dash replaved only to have it warp again. It's a design and material issue, not a random chance. The plastic they're using is garbage.
