GM able to add diesel to half-ton pickups if market demands it

A few years ago, the trend in half-ton pickup trucks was ultra-luxurious trims, often with the words "limited" or "platinum" tacked on after the model name. That was well and good, but we like this latest fad a lot more - diesel engines. First, Ram came to bat with a 3.0-liter, V6 turbodiesel for the 1500, then Nissan announced that the next-generation Titan would be getting an eight-cylinder Cummins diesel.
Now, word is coming in from AutoGuide that General Motors can, if it so chooses, drop a diesel engine into its light-duty trucks. The plot thickens, though, as it turns out that said diesel would be the same one Ram is using for its truck. According to AG, that engine comes from VM Motori, which GM owns a sizable chunk of. Therefore, GM can snag the 3.0-liter, V6 diesel for its trucks just as easily, if not more easily, than Ram.
If it's so easy for the Detroit-based manufacturer to access the engines, why not offer the a diesel-powered Sierra and Silverado from the start, then? According to GM spokesman Tom Wilkinson, The General doesn't seem so confident in a diesel pickup outside of its HD offerings. According to Wilkinson, the cost-benefit ratio doesn't line up for customers, thanks to both the impact on the truck's sticker price and the higher price of diesel, in general (the national average for a gallon of diesel is 43 cents more than a gallon of 87-octane unleaded).

2022 Chevrolet Silverado LT Trail Boss adds 3.0-liter diesel option

Order books just opened for the 2022 Chevrolet Silverado, which, in case you hadn't heard, is almost unchanged compared to the 2021 Silverado. The overhauled Silverado and GMC Sierra that we caught in spy shots several times last year and were expected to launch this year have been delayed. Until that pickup gets here, Chevrolet and GMC will add "Limited" to the names of the Silverado and Sierra. Fleet guides for next year's truck show the official model name as Chevrolet Silverado 1500 LTD. There are a few interesting features coming next year, though, like the Multi-Flex tailgate joining the options list for Silverado HD trucks. GM Authority also reports that the 2022 Silverado LT Trail Boss adds the 3.0-liter oil-burner with 277 horsepower and 460 pound-feet of torque as a third engine option, which should be a big treat for the off-roading crew. Whereas the GMC Sierra AT4 already offers the 3.0-liter diesel, the Silverado LT Trail Boss only offers the 5.3-liter and 6.2-liter V8s, both bolted to GM's ten-speed automatic transmission. Then there's the Custom Trail Boss that adds the 4.3-liter V6 as an option, and it and the 5.3-liter V8 only get 6-speed automatics. At the moment, Silverado trims that offer the Duramax charge a $1,045 for it over the 5.3-liter V8. If that gap holds true for next year, the diesel will just about evenly split the price difference between the LT Trail Boss with the 5.3 and the 6.2.   Elsewhere in the range, Driving.ca said Canadian fleet guides show the 4.3-liter V6 and lower-spec 5.3-liter V8 with Active Fuel Management (AFM) instead of Dynamic Fuel Management (DFM) disappearing from next year's base Silverado WT. To clarify, AFM only shuts off half the cylinders in certain conditions, whereas DFM constantly adjusts how many cylinders are firing all the time. As it stands, that would leave the 2.7-liter turbo four-cylinder as the only engine option. However, those other two mills were the only ones left in the lineup that shift through a six-speed transmission, making it possible that they'll rejoin the options list with at least two more gears to choose from. It's not clear if GM will sell the Limited models alongside the majorly upgraded 2022 Silverado. The automaker did just that a few years ago, selling the previous-gen truck as a Limited trim alongside the then-new, current-gen. It certainly wouldn't be the only company to do so, either.

GM recalls 55,000 trucks, SUVs for separating axles, fuel pump failures

General Motors issued four separate recalls covering eight of its truck and SUV models for issues related to fuel pump and half-shaft failure. In total, the four campaigns include more than 55,000 vehicles spread out over three brands and six model years, but they've sorted themselves neatly into two categories. Let's dive in.  Axle separation Four models are being recalled for potential axle separation: The 2023 Cadillac XT5, 2023 GMC Acadia, 2023 Chevy Blazer and 2023 Chevy Traverse. The number of units affected is incredibly small (10 units each times two recalls, for a total potential population of just 20 cars). In each case, a small number left the factory with half-shaft assemblies that may have been missing the retention rings that keep them in place, possibly allowing the axles to separate or eject from the transmission. In the case of the XT5 and Acadia, it's the right-side axle assembly; Chevy dealers, however, will have to check the left side.  Fuel pump failure Again, we have multiple vehicles being recalled for similar issues, but in this case they're a bit more distinct. The first of these recalls covers the 2021-2022 Chevy Equinox and 2022 GMC Terrain. GM says a supplier-initiated change may have led to fuel pumps shipping with inadequate clearances to allow for the prescribed flow of fuel, meaning the pump could starve the engine. Customers experiencing the issue may see a check engine light and experience engine hesitation. In some cases, the cars may not start at all. Chevy and GMC will replace the units in question with correctly specified pumps.  The second recall covers a fairly specific cross-section of GM's HD truck lines. 2017-2019 Silverado and Sierra HD trucks sold with the diesel engine and a dual-tank configuration may have shipped with a rear fuel pump that is susceptible to fouling by debris, preventing fuel from properly transferring to the front tank, or, in extreme cases, resulting in a collapse of the rear tank. This issue can lead to inaccurate/erratic fuel tank readings, engine hesitation, a check-engine light or failure to start.  In both cases, GM will inspect and replace faulty units free of charge for customers. Expect notifications to be delivered by March.  Related video: Recalls Cadillac Chevrolet GMC Ownership Safety Truck SUV
