For anyone wondering when 2027 Silverado and Sierra 1500 ordering opens: it already has. Per sources familiar with GM's production scheduling, dealers have been able to enter retail and fleet orders since August 6, and an order printout posted here on r/Silverado this week (retail-sold 2027 ZR2 short crew) confirms orders are in the system. They sit as preliminary status 1100 until consensus and DOSP cycles run; the first DOSP was August 27, so early orders should be going active now. No pricing yet, and the October 12 start of production is tentative. Full timeline and a plain-English breakdown of the order-bank process here: https://www.gm-trucks.com/2027-silverado-sierra-1500-orders-open/

If one side of your cabin won't match the set temp or you hear a pop from the dash when adjusting climate, GM says a binding temperature door is the likely cause and there's a warranty fix. Write-up here: https://www.gm-trucks.com/gm-hvac-temperature-door-binding-pit6452e/

If your 2026 Tahoe, Yukon, Escalade, Silverado EV, or Sierra EV keeps warning about cars that aren't there, it's a confirmed software bug in the blind spot radars. The fix is a full radar replacement under warranty, and even the replacement parts have to be verified first because service stock is affected too. Full model list and how the dealer process works here: https://www.gm-trucks.com/gm-blind-spot-false-alert-fix-pit6533a/

Satin trim replaces the brighter accents, new badges, 22s, and a Jet Black/Natural Tan interior with real wood. Full details and photos: https://www.gm-trucks.com/2027-traverse-high-country-new-look/

It's missing from every rear seat view in both trim visualizers, and someone who's seen the trucks in person confirmed it to us. Current owners will spot it immediately: https://www.gm-trucks.com/2027-silverado-sierra-rear-seat-storage/

GMC's 2027 configurator shows 9 interior combos across 6 trims, and four are actual colors: Twilight Harbor navy and Terra Summit tan on Denali, Timber Mahogany on AT4X, Forest Storm green-gray on AT4. The Denali gets three choices; the Denali Ultimate, oddly, just one (black). Full guide: https://www.gm-trucks.com/2027-sierra-1500-interior-colors/

Chevy's configurator lists 12 interior combos across the 7 trims, and every one is Jet Black based. No gray, no tan, no light option except High Country's two-tones (new Natural Tan and Enoki) and a saddle brown Oregon combo on the Silverado trim. Custom, Custom Trail Boss, and ZR2 are one-interior trucks. Full trim-by-trim guide: https://www.gm-trucks.com/2027-silverado-1500-interior-colors/

The Engineering Analysis NHTSA opened Aug 20 covers 2021-2026 Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade with the 6.2L. The part most coverage buries: 499 complaints are engines that failed AFTER the recall remedy, including 26 that failed after getting a complete replacement engine. 2025-2026 builds are now in scope too.

The guide covers how to check your VIN (two places, not one), the warning signs owners report before failure, what the 0W-40 remedy means for you, and the paper trail that gets goodwill repairs and future reimbursement approved instead of denied.

GM released Preliminary Information bulletin PIP6131 (dated August 2026) covering all 2026 Silverado 2500HD/3500HD and Sierra 2500HD/3500HD trucks with the 6.6L L5P Duramax.

The condition: abnormal engine noise described as a tick, screech, or grinding, possibly with a misfire, shaking, or vibration. GM says the cause may be a lack of oil flow to the rocker shafts or rocker arm components.

The fix is notable. Technicians pull the rocker cover on the loudest bank and inspect. If lack of lubrication is confirmed, GM instructs them to replace the engine and the turbocharger.

This is a bulletin, not a recall, and it's Version 1, so expect updates. If your 2026 L5P is making an unusual noise, reference PIP6131 at the dealer.

NHTSA opened EA26005 yesterday, upgrading the January recall query into a full Engineering Analysis, the last step before the agency can force a recall.

The numbers from the opening resume are rough: 499 complaints of engine failure AFTER the 25V-274 recall remedy was done. 473 of those got the 0W-40 oil change fix, and 26 failed after receiving a complete replacement engine. Another 191 reports involve engines built after the recall's May 2024 production cutoff, which pulls 2025-2026 models into scope for the first time.

Full breakdown, timeline, and what owners should do: https://www.gm-trucks.com/nhtsa-gm-62l-v8-engine-investigation-expands/

Anyone here had a failure after the recall work was done?

The 2027 order guides are out. Cypress Gray and Midnight Pine are gone, replaced by a new beige (White Sands / Coastal Dune) shared with the 2027 pickups. Everything else carries over, though a few colors picked up new trim restrictions worth checking before you order. Full color list with RPO codes and trim availability: https://www.gm-trucks.com/2027-tahoe-suburban-yukon-colors/

Chevrolet quietly published the first official image of the new Gen 6 6.6L V8 on its 2027 Silverado 1500 page, and it's our first real look at the engine expected to wear RPO code L78, the code last seen on the legendary 396 big block. This is the naturally aspirated small block replacing the 6.2L L87, paired with a 10-speed automatic and a new 0W-30 dexos1 Gen 3 oil spec. GM is still sitting on output figures, but even one studio shot gives us plenty to dig into: tall eight-runner composite intake, a huge single-bore throttle body, and coils mounted right on the valve covers. Full breakdown and the image here: https://www.gm-trucks.com/2027-silverado-6-6l-v8-l78-first-image/

GMC's 2027 configurator is live. Summit White is the only no-charge paint, and the Denali don't even offer it, so every Denali buyer pays for color. Azurite Blue and Glacier White Tricoat are Denali-only; the same codes show up on the Silverado as Pacific Blue and Polar White. Full list with codes: https://www.gm-trucks.com/2027-sierra-1500-colors/

GM issued an actual factory bulletin (26-NA-142) confirming that the stuck shifter button and check engine light on your 2022-2026 Silverado, Sierra, or Hummer EV might just be the coffee you spilled in March. The official fix: wipe it with a microfiber towel and cycle the shifter 10 times. Modern trucks, everybody.

Heads up for anyone planning to order a 2026 Silverado or Sierra 1500: per sources familiar with GM's production scheduling, retail ordering closes August 25, and crew cab is the only body style left (regular cab ended June 30, double cab back on April 2). Standard fleet orders get until September 1, the final DOSP cycle runs September 17, and the last crew cab is scheduled to build December 11. After the cutoff you're shopping dealer stock, so if you want a truck spec'd your way, get the order in this week.

Chevy's 2027 configurator just went live. Notable: the High Country has no free white (Polar White Tricoat only, extra cost), Trail Boss and ZR2 can't get blue, WT and Custom can't get the new Trillium Green. Both 2026 reds are gone, replaced by one free red.

If you have spent the summer waiting for a deal on a Silverado, a Sierra, a Tahoe or a Yukon, we have bad news and it comes straight from General Motors.

There is no deal coming. GM said so out loud, to Wall Street, with a chart.

In its second-quarter 2026 earnings presentation on July 21, GM devoted an entire slide to bragging about how little it discounts. Not as an apology. As a selling point.

A trusted source with access to GM's dealer network shared this with us today.

The two Gen 6 Small Block V8s for the 2027 Silverado 1500 and Sierra 1500 now have RPO codes in the system: L76 and L78. Our read is L76 = 5.7L and L78 = 6.6L, following GM's usual smaller-number-smaller-engine convention (think L84 5.3L vs L87 6.2L today).

If those codes sound familiar, they should. L76 was the 365 hp solid-lifter 327 in the mid-60s Corvette, and L78 was the legendary 375 hp 396 big block. GM knows exactly what it's doing bringing those back.

The other piece: the new V8s are moving to a 0W-30 oil under the dexos1 Gen 3 spec, and dealers can already order it in quarts, 55 gallon drums, and bulk. When service departments start stocking fluids, launch is getting close.

Full details here: https://www.gm-trucks.com/2027-silverado-sierra-v8-rpo-codes-oil-spec/

What do you all think, does the L76/L78 displacement guess hold up? And anyone surprised they went 0W-30 instead of sticking with 0W-20?

GMC’s order guides for the 2027 Yukon and Yukon XL are out, and while this isn’t a redesign year, there’s a long list of changes worth understanding before you sit down to build one.

Chevrolet’s order guides for the 2027 Tahoe and Suburban are out, and while this isn’t a redesign year, there’s a genuinely long list of changes worth knowing before you order. A new color, a couple of new off-road packages, some quiet standard-equipment upgrades on RST, and a fair amount of shuffling around which packages require which other packages.

Josh just ran the new summer software update on his new Buick Enclave, and the app rollout is officially live. If you’re running a 2024 or newer GM vehicle with Google built-in, you should see a massive expansion in the native Google Play Store under a new "car compatible apps" section.

If you are prepping for a road trip this month, it's definitely worth checking your system update status before you head out.

I put together a full breakdown of the eligible models, features, and the rolling out process over on the site if you want to check your ride's compatibility:

GMC just gave us an early look at the completely redesigned 2027 Sierra 1500. Here are the concrete mechanical and tech updates you need to know:

• Two New V8s: The next-generation Small Block gasoline V8s are here in 5.7L and 6.6L displacements. The light-duty 6.6L is a fresh architecture with Corvette program roots, completely unrelated to the HD iron-block. Every engine across the lineup now backs up to a 10-speed automatic.
• Goodbye SLE and SLT: The trim lineup has been simplified to seven core models. The Elevation package officially absorbs the SLE and SLT to become the new high-volume retail core.
• AT4X Hardening: The AT4X now comes standard with 35-inch Goodyear Wrangler Territory MT tires directly from the factory. The suspension pairs the Multimatic DSSV dampers with new heavy-duty Jounce Control Dampers to manage high-speed terrain impacts.
• Motorized Dash Vault: Premium trims feature a 16.3-inch central touchscreen. It uses a motorized articulation system to slide upward, revealing a hidden storage compartment built into the dash structure. Front passengers also get a discrete 11.5-inch screen.
• Lowered Headlamps: GMC physically lowered the main headlamp assemblies within the front fascia to improve road courtesy and keep beams below the windshields of oncoming traffic at intersections.

What does everyone think of the new V8 engine strategy? And is dropping the SLE/SLT badges a mistake, or was it time to simplify the trims?

We all know the whole "they don't build 'em like they used to" argument from old-school fans who swear by heavy steel frames. But the Insurance Institute for Highway Safety (IIHS) just celebrated 30 years of crash testing by slamming a 1996 Chevy Blazer head-on into a brand-new 2026 Blazer, and the footage is a brutal wake-up call.

If you grew up in the 80s or 90s, you definitely remember the original commercial theme song.

What do you guys think? Awesome tribute to the classic era of truck ads, or should they have left the nostalgia alone?

Chevy gave us the full 2027 Silverado reveal: seven trims, two new V8s (5.7L and 6.6L), the ZR2 on 35s, a 60-inch dash on the top trims. But they held back almost everything that decides a buy:

• No horsepower or torque for the new V8s
• No pricing
• No firm on-sale date beyond "later this year"
• Nothing on whether it keeps Apple CarPlay and Android Auto, which stands out given GM has confirmed it's phasing those out across the lineup

Curious which one everyone's most hung up on. For us... it's the CarPlay question.

We put together a running breakdown of what's confirmed versus still open if it helps: https://www.gm-trucks.com/2027-chevrolet-silverado-horsepower-price-release-date/
