According to an updated Technical Service Bulletin (PIT5687B) released in May 2026, a simple loose wiring pin is causing massive electrical headaches for owners of 2019 through 2026 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups.

Hey everyone, we just put out a detailed breakdown of a pretty crazy recall GM just dropped (NHTSA Campaign 26V289). It comes with a strict "Do Not Drive" warning and a Stop Delivery order.
Turns out, a batch of transfer cases left the factory without an oil pick-up tube. Without that lubrication, your front or rear wheels can completely lock up without warning while you're driving at speed.
It is a very small batch (mostly 2026s and some 2015-2020 SUVs that recently had replacement parts installed), but the crash risk is obviously huge. If your VIN is on the list, GM is covering the tow and replacing the entire transfer case assembly for free.

I'm curious to hear from you:
We have both a Chevrolet and a GMC in our fleet right now, so this debate hits close to home.
Even though they are the exact same truck underneath the sheet metal, a recent viral thread showed us that the choice usually boils down to three things:

If you chose the red letters over the gold bowtie (or vice versa), what was your ultimate dealbreaker?
Is the audio going silent in your Chevrolet or GMC? We see the posts across our forums: the music drops out, the navigation goes quiet, and even the familiar turn signal click disappears. It is an incredibly frustrating experience when you just want to enjoy the drive in your premium vehicle.
The good news is that General Motors is listening, tracking the root causes, and actively releasing solutions. In May 2026, GM updated a preliminary Technical Service Bulletin (PIT6406H) to help dealership technicians properly diagnose these audio complaints.
The issue boils down to a mix of software glitches and specific amplifier hardware anomalies. Here is a breakdown of what is happening behind the dashboard, what GM is doing to make it right, and how you can figure out which specific issue is plaguing your rig.

Chevy just released the 2027 order guide for the Blazer EV, and the most significant update is the transition to a native NACS charging inlet paired with a new suite of dealer-provided adapter packages. Alongside the charging hardware update, the high-performance SS trim is getting a stealthier exterior by swapping the old machined-face wheels for standard 22-inch Gloss Black aluminum versions. The lineup also sees a new White Sands paint option, the removal of Galaxy Gray, and some minor repackaging like adding the Bose audio system directly into the Super Cruise package. We compiled the complete list of hardware tweaks, styling changes, and accessory deletions over at GM-Trucks, which you can read right here: https://www.gm-trucks.com/2027-chevy-blazer-ev-native-nacs-upgrade/
You have to love modern automotive design. You make a sleek, flush-fitting charge port door, slap a shiny Cadillac crest right in the middle of it, and then act surprised when everyone assumes it's a push-button.

It's gotten so bad on the new 2025/2026 Cadillac Optiq that GM actually had to issue a Technical Service Bulletin (PIC6620A) because dealerships are getting complaints about "stuck" or hard-to-open charge doors.
The official, published cause in the GM diagnostic document? "Customer pressing in the wrong location." People are mashing the decorative Cadillac shield, which does absolutely nothing. To actually open the door, you have to press the blank upper right-hand corner of the panel.
General Motors just crossed a massive technological milestone… and honestly, you’re welcome, GM. As of this week, drivers have officially logged 1 billion hands-free miles using Super Cruise, and the GM-Trucks.com team personally contributed 5,367 of them to the cause.

The order banks for the 2027 Chevrolet Traverse are set to open on June 18th, and while the rumor mill has been buzzing about a couple of new exterior paint options, the actual GM order book reveals a much bigger story.
We got our hands on the official 2027 Traverse changes, and it turns out Chevrolet is bringing a brand-new technology feature to the cabin and completely shaking up the standard wheel offerings across the High Country, RS, and Z71 trims.
Here is the complete breakdown of what is actually changing for the fourth year of the third-generation Traverse.

I just finished combing through General Motors' Q1 2026 financial report. If you were worried about the future of gas-powered HD rigs and V8s, this earnings report should help you sleep a little better tonight. Wall Street was expecting an average quarter, but GM completely crushed it, and it's our trucks doing all the heavy lifting.
I wrote up a full breakdown over at GM-Trucks, but here is the TL;DR of what is actually happening with GM's money:
If you want to read the full deep-dive and see all the numbers, you can check out the article here: https://www.gm-trucks.com/gm-q1-2026-earnings-truck-sales-ev-pullback/
What do you guys think? Does seeing GM eat a $1.1 billion loss on the EV pivot just to get back to focusing on highly profitable gas trucks validate what truck owners have been saying all along?
If your dipstick is reading a little low between oil changes, you might be gearing up for a fight with your dealership's service department. I just published a deep dive over at GM-Trucks breaking down GM’s official Technical Service Bulletins on what they consider "acceptable" oil consumption, and the numbers are pretty surprising.
Here is the TL;DR of what the factory tells their techs:
Unsurprisingly, over on our forums, owners completely disagree that a modern precision engine should burn that much oil. We've seen vastly different trends between the 2.7L turbos, the 5.3L V8s (where oil level is critical to avoid lifter failure), and the 6.6L gas HDs.
If you want to read the full breakdown, the dealer checklist, and how to prepare for the oil consumption test, you can check out the full article here: https://www.gm-trucks.com/gm-normal-engine-oil-consumption-guidelines/
What are you guys seeing in the real world? How much oil is your 5.3L or 6.2L actually burning between 5k mile intervals?
When General Motors announced they were sending a one-of-a-kind military truck to the Barrett-Jackson auction block, we knew it would draw serious money. We also had a strong feeling we knew exactly who might be holding the winning paddle. Over the weekend, the first-ever publicly offered Infantry Squad Vehicle Utility crossed the block. It hammered for an incredible seven figures, and the keys went to none other than Rick Hendrick.

Hey everyone, just wanted to give a heads-up on a massive headache happening with the 2021-2026 full-size GM SUVs. Dealerships have been chasing parasitic draws and random alarms on these trucks for a while, and GM just put out a bulletin explaining why.
It comes down to the "glass breakage loop" in the rear quarter windows. The BCM sends an 8-volt signal through the defogger grid and the side glass. If the resistance spikes above 20 ohms, the truck thinks someone broke the glass. It either triggers the alarm or stays awake all night monitoring the circuit, killing your battery.
The kicker? GM explicitly stated that if the connection is damaged by aftermarket window tint or decals, it is NOT covered under the factory warranty.
If you're dealing with this, check your rear glass connections before you let the dealer charge you for diagnostic time. I did a full write-up breaking down the technical bulletin and what codes the dealer will look for here:

If you think $100,000 is strictly Cadillac Escalade territory, it is time to recalibrate your expectations. Chevrolet has quietly pushed the boundaries of what a family hauler can cost, transforming the Suburban from a utilitarian people-mover into a six-figure luxury cruiser.

We are officially into April, which means the clock is ticking on one of the easiest ways to keep cash in your pocket when buying a new Chevrolet. https://www.gm-trucks.com/costco-chevrolet-truck-month-discounts-april2026/
Civilian buyers rarely get the chance to purchase actual military hardware straight from the manufacturer. That changes at the upcoming Barrett-Jackson Palm Beach auction.
March 2026 is officially a month for the history books at General Motors, Chevrolet & GMC.
General Motors has issued Customer Satisfaction Program N262546840 to reimburse exactly 915 owners of the 2025 and 2026 Chevrolet Silverado EV in the United States. The $50 reimbursement addresses an accidental charge for a back-up alarm calibration that was never provided with the vehicle.
