John Goreham Contributing Writer, GM-Trucks.com 9-11-2019 General Motors has announced that NHTSA is mandating a safety recall for the following vehicles: 2014-2018 Chevrolet Silverado and GMC Sierra Pickups (1500 / 2500 / 3500) 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles 2015-2017 Cadillac Escalade NHTSA reports that the amount of vacuum created by the vacuum pump may decrease over time. The group says that as the vacuum level drops, the brake assist decreases, and that this increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. This new recall covers 3.4 million vehicles. The Problem: The brake pump uses engine oil to lubricate itself. If the pump becomes clogged with engine oil sludge the units ability to create vaccum is diminished over time. As a result, braking force and ability also drops. The issue is usually accompanied by a "Service Brake Assist" warning message in the dash. The Fix: GM will reprogram the computer that controls the secondary brake assist pump. The secondary pump will now activate at lower speeds and different situations quicker to compensate for any lost output from the main pump. Since the pumps are not failing, GM has decided not to replace them. GM's number for this recall is N192268490. In compliance with federal law, GM will notify owners, typically by snail mail. GM says that its dealers will reprogram the Electronic Brake Control Module. However, GM has not yet provided a notification schedule. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. If you own one of these vehicles and wish to check to see if your vehicle is included (or not) you can do so at this link immediately. As with every safety recall, customers will not be charged by GM for the needed repairs or modifications. NHTSA's public information on this issue indicates that many accidents have been reported to NHTSA including some with injuries. This recall is the result of a NHTSA investigation that lasted nearly a year. In its investigation report, NHTSA noted the following details about the problem: -
Greetings. New guy here, so please freely call me out an any forum missteps. I started out with a base model 2018 GMC Sierra 4wd, regular cab, standard bed. It has a snow plow package and 3.42 gears. Onyx Black. No frills. I'll try and remember the order in which I did everything. All work do date has been done in my driveway, which I'm reasonably proud of because I work a job where I mostly send emails and sit in meetings. -- Debadging happened the first day of ownership... just my thing, costs nothing. -- Blacked out my front badge with with plasti dip -- Removed the air dam -- Cover King carpeted dash mat added, in the color of 'wine'. -- Cover King saddle blanket seat covers added in wine/whiteish.... returned after about a month because they were coming apart at the seams in a quite literal sense. Back to my grey cloth seats. -- Added a Rough Country 2 inch level (those cheap spacer things that are shaped like 'C' -- Brow tint on the windshield and multiple layers of Collinite way done by Motoring Images in Lee NH (ok, this wasn't in my driveway) -- Airaid modular intake and filter added. Sounds great, I'm a fan. -- Borla ATAK cat back system with polished tips. Sounds wonderful. -- Diablo Intune3 handheld tuner, custom (non dyno, remote) tuned further for 91+ and some extra oomph by Lew. -- Mudflaps installed and ultimately removed because they were the no drill kind and drilling would have helped from losing one in a carwash or who knows where, so those are gone.

Good morning everyone, I recently purchased a 2018 GMC Sierra Crew Cab SLT All-Terrain package. I'm personally wanting to install a leveling kit and I believe I've selected one. I've read a lot about leveling kits for 2017-18 trucks and this seems like a great kit. However, there isn't many reviews on this product by ReadyLift. The appeal of this lift is the UCA replacements and the <2" height it allows. I'm wanting to go with 305/55/20 or 285/60/20 tires with my stock AT wheels and I want as much clearance possible. I found maybe 2-3 members on here with this lift and I'll quote them below. My question is, will this work with my All-Terrain package? In the description of the kit it states, "Will not work on Z71 packaged vehicles with factory Rancho® struts." Yet on ReadyLift's website, there is nothing supporting that statement. Does anyone have any information or review for this kit? Thanks! -
Has anyone had a rear compressor issue with a new Yukon XL Denali? My wife and I bought the vehicle at the beginning of October 2018 and within a month the rear compressor began running excessively. We took it into the dealership with bought it from and the service rep heard the noise but was unable to reproduce it later in the day with the technician so they sent us away with the vehicle. The noise became more and more regular so we took it to a dealership near our house and they heard it and acknowledged the problem, this lead them to replacing the rear compressor. The change of the rear compressor didn't do the trick and the excessive running persisted, this is where the frustration really set in. The service technicians were going to run diagnostics and service the vehicle after we brought it in MLK Day. The service department manager interrupted the process and essentially tried to bully my wife into accepting the fact that this is normal behavior for a GMC Denali line vehicle. She left the dealership in tears. I called the service manager in disagreement with 1) his treatment of my wife and 2) disputing the fact this is normal. His response was the discharge the video with a bogus report emphasize the vehicle was in intended working condition. Now the Denali is sitting at another dealership while they try to replicate the issue. It occurs 30-40% of the trips we take in the vehicle and the rear compressor will run anywhere from a few seconds to 20 minutes. Has anyone else had this issue and found a resolution? I'm to the point I'm almost willing to just sell the vehicle back for a loss to be rid of it. -
Had my truck worked on at a body shop(dent fix and new windshield) then straight to a proper detailing. I assume one of the two disconnected my batteries (L5P Durramax). Now, the buttons and controls on the steering wheel do not respond. Confirmed with both shops, nothing was disconnected from the steering column. Everything else, horn, dash, lights, radio, etc. All function correctly. Only the stero paddles, and menu nav buttons do not work. Scanned all the modules for codes and received back 2 codes in the Instrument Panel Cluster. DTC 1: B3622-39 Steering Wheel Controls Signal Circuit - Internal Malfunction - (No ****** Sherlock) DTC 2 : U1510-00 LIN Bus Lost Communication with Device 0 - (Ah yes, Device 0, obviously). I am not sold on the clock spring still as I don't have any SRS module codes. Repair manual says those codes together is a short to ground. Cheryl on-top was this YouTube video, Anyone have enough knowledge to help me figure if it's a bad module or a cut wire? -
I understand this topic has been around for some time, but I recently purchased a 2019 Silverado LD (same body style as the 2014-2018 models). When I look for aftermarket mods/information, I have been referencing the 2018 model year. In particular, my Silverado is a 2019 LD LT Z71, Double Cab, Midnight Edition w/ the All Star package (a lot to digest there!). The mods I have done in no particular order of completion are: 2" Zone Leveling Kit Rough Country rubber bed mat Driver & passenger window tint (35%) Upgraded to LED bulbs in cargo, reverse and license plate lights Replaced stock antenna w/ 3" stubby Added 4 Bully hooks to bed sidewalls Tinted license plate covers (not too dark as you WILL be pulled over) GM tri-fold tonneau cover (manufactured by Advantage Truck Accessories for GM (GM Part #19367127). Appears to be very similar to the Extang Trifecta 2.0. BackRack #15024 w/ tonneau kit part #50120 (fits perfectly w/ that tonneau cover, but you won't find it listed on BackRack's site) Rear seat GM floor liner Front seat GM all weather floor mats Amooca no-drill mud flaps N-Fab cab length side step bars textured black Apeman mini dash cam Range Technology AFM disabler K&N 33-2129 Performance Air Filter (AIRAID Modular Intake Tube to follow...) and the best for last, stainless steel, Magnaflow MF Series Black cat-back - dual split rear exit exhaust, 4" black coated tips (these pipes were made for the 5.3 - such a perfect growl!!) Future mods would include 33" Nitto Ridge Grapplers or DuraTracs & a little more lift.

Do the 2019 GM Step Assists fit the 2014-2018 model years? Trying to figure out if the 2019 Sport Steps will fit my 2016 Silverado. Thanks. -

I'm trying to figure out what the max tire size is I can put on stock 20s in the 33" range. I'm looking at KO2s right now which I know BFGs run a little small. What is the max I can run if I level with a 2.0" level or if I run stock suspension? I have a 2018 Sierra Crew Cab NHT with stock 20" wheels. I tried doing some searching and I think I can fit a 33 no problem but then I see other posts that just confuse me on the matter.- 88 replies

2016-2018 GMC Sierra Elevation grille that's been professionally painted black. This is a brand new OEM grille. I bought it from a member on here, but also decided to go with a different grille. The grille itself looks fantastic, the only reason for going with another grille is I have seen another truck identical to mine with the same grille, and I want to have something different... $500 shipped. Only asking what I paid for it. Current location: 54016 Thanks!

Not to beat a dead horse but I can only seem to find info on 2014-2016.... My Truck: 2017 Sierra CC SLT 5.3 with the stock 20in (20x9) rims & Bilstein 5100s at 1.25" I want to get new tires (nitto ridge grapplers or toyos etc) and I would like to move up to a 285/55r20 if possible. From what I've read I know the UCAs changed for 2017 making guys experience rubbing on the UCAs with 33s on levels. Was wondering if anyone had done a 285/55 on stock rims with stock height or Bilsteins and did they rub, or rub all the time/just full lock? TIA -Ed -

Starting off I am sure there are threads that answer these questions but I had trouble finding answers, and it’s my first time lifting a truck so trying to be thorough. So I have my 2018 1500 Z71 CCSB that once my warranty runs out I plan to lift it, leaving stock till that day, I’ve been looking at BDS lifts and Zone, the 6” and 6.5” is the height I want to go with. Zone’s 6.5” kit from what I’ve learned is a maxed out 4.5” kit basically. BDS 6” has either the coil over package or the strut spacer package I believe, I have stamped steel control arms for UCA, LCA I can’t remember exactly and will check when I get home. My questions are based toward the BDS option as I do not want to use the zone unless I have to My questions are is it worth it to get the coil over system vs the kit without coil overs, because that’s almost 1700$ more? What kind of installation costs is it typically for a installation? Has anyone had issues since they installed their kit? if I go with the coil overs, should I do the base set of coilovers or the ones with DSC? Id like to have 4WP install the kit so I could have their warranty on the install along with the BDS lifetime warranty, but not sure if they would do the install (I haven’t called them to see about this yet) I’m going to use the custom offsets site to see what wheel/tire combos I can run but if y’all have pictures that would be awesome to see to get a ballpark -
Looking for some tire recommendations for my 2018 Z71 Silverado 4x4. I currently have a Moro fab lift (3” in the front and 2” in the rear) and am looking to run 33’s. Anyone running 275/70r18’s or 285/70/r18’s or 285/75/r18’s? Drop pictures and recommendations if you have them. Looking to keep my stick 18” rims.

So I have recently purchased a Range AFM disabler for my 2017 Silverado 1500 E-assist because of the constant stopping and starting at stop lights, exhaust drone from V4, weird shifting from V4 to V8 and my transmission liking to jerk/shifting hard every so often. After installing the Range device, it has solved my transmission issues, disabled stopping and starting at stop lights, and has been keeping it in V8 mode 24/7! The only thing I have noticed is that when I am decelerating from a speed of around 50 MPH or more, the engine will have a fast repetitive backfiring popping sound until i either get back on the gas pedal or have reached a speed of 35 MPH. It seems to happen when i am decelerating slowly and not fast, starts to backfire when it starts to downshift at around 900-1100 RPMs I have a flowmaster Super40 cat-back dual 2.5 inch exhaust with the third "cat" still on. It used to not backfire when the AFM was active BUT when decelerating, it would switch back into V4 mode. is there a way to fix this? Is there too much freeflowing exhaust? Can this backfiring through the exhaust cause any damage if left unfixed? Thanks, -Hunter -
Hello all! Glad I found a place with some knowledgeable folks so I can ask my modification questions. As of a few days ago I am a proud owner of a 2018 Z71 All Star Edition Chevy Silverado 1500 Crew Cab. I absolutely love this truck but what truck would be complete without a couple of modifications!? I'm running into a situation that hopefully someone else has run into and solved. I want to add a storage unit under the rear seats; however, I also want to add the 10 inch kicker sub woofer that comes from Chevy to give my stereo a little fuller sound. The only place that 10 inch speaker seems to be able to go is under the passenger side rear seat. I have yet to see an under seat storage unit that is basically only half the size so the speaker can fit too, Has anyone done this and if so what storage unit did you get that allowed for both the speaker being mounted and storage bin placement? I do the apartment thing so I don't have the resources or space to fabricate my own as I have seen some on youtube do. Any guidance would be great! Thanks, -
Hey all, I own a 2018 Silverado 2500HD LTZ Z71...The damn headlights are that terrible yellow color, Did Chevy not put LED lights on any of the 2500 models? Has anyone replaced the whole light assembly or even just bulbs to achieve the clearer look? If so please share and checkout the photo below of my headlights compared to the illuminated bow tie. Thanks for the help.

I have some items/ parts I no longer require or desire. Would love to get them out of my garage. Everything is off a 2016 Silverado 1500 Z71 LT Crew Cab Short Bed. - Bed caps - Headlights (no harness) Continued: -
Ok so this is my first post on hear but im not new to this place ive used this forum thousands of times in the past as I am only 18years old i started off in a 03 gmc 1500 short bed reg cab stick shift, but up here in mass 2wd wasnt gonna cut it so after that I had a trailblazer for the past year and now Ive been lucky enough to get back into trucks with my new 1500 that i'm leasing, its an LT Z71 with 4wd and the 5.3. Im perfectly happy with how the trukc is as of now but I definitely want/"need' it to be leveled as my whole family Cousins, aunts, uncles, father, and mother have atleast a leveling kit or just a beefy vehicle as now im the only one without some ground clearance, but i dont know which leveling kit is the best choice as i want to stay under 3 inches. So if anyone could help me it would be great id like to know the best kits under a few categories. 1-Best ride. 2-Best bang for your buck. 3- Eastiest install. 4- Best offroad capability. 5- The best kit in general. I have been told the Bilstien 510 is a great choice but before i pull any triggers i'd like to know all my options as I won't be getting the kit within a month or two as the truck only has 900 miles. Thank you -
Hello, I have a 2018 Silverado, around 11000 miles on it. Driving the other day, lost power around 35 mph, pulled into a parking lot, re started the truck and checked to make sure I was in 2wd etc. Began driving again, toward home due to something being wrong and same issue occurred including check engine light. Had vehicle towed Friday night when it happened, at dealer now which isn't open until tomorrow. Has anyone experienced anything similar? -

Zane Merva Executive Editor, GM-Trucks.com 10/30/18 Day one of SEMA 2018 is almost already in the books and we've barely made it through the South Hall (which houses the Truck/Off-Road section) trying to get our eyes on every customized 2019 being shown inside exibitor's booths. There's no way we'll see everything but what we have seen already is impressive. Accessories for the all new Sierra and Silverado are coming out in force, even if the trucks are still trickling into dealerships. Although the new fullsize pickups are GM's hot new thing, the automaker has not made it a focus of this year's show. That means, while we're seeing a ton of 2019 Silverado and Sierra, there are 2x as many 2019 Dodge Ram and 5x as many Jeep Wranglers. Here's what we've seen so far. We'll add more photos to this thread as we take them.

I know a few people have had this issue with their HIDs jiggle in the projector housing so I figured id make some videos and put them on youtube for all to see. I talked to GM Canada and they wanted me to drop my truck off for a full day to diagnose the problem and pay out of pocket. Im now thinking its a better idea to put LED's in instead. Has anybody done this before? Ive found lots of videos of the 2014/2015 LED conversion but nothing for the 2018. Thank you.
