Engine block heater issues force GM to recall 324,226 diesel heavy duty trucks

General Motors has issued a recall on 324,226 diesel heavy duty trucks that could be susceptible to short circuits, and consequently, potential fire. The recall affects several models of heavy duty Chevrolet Silverados and GMC Sierras with optional engine block heaters. GM is recalling seven different truck models spread across three years. The recall affects the 2017-2019 Chevrolet Silverado 2500HD, 2017-2019 Silverado 3500HD, 2019 Silverado 4500HD, 2019 Silverado 5500HD, and 2019 Silverado 6500HD, plus the 2017-2019 GMC Sierra 2500HD and 2017-2019 Sierra 3500HD. Specifically, it includes these models with the 6.6-liter Duramax diesel engines and the optional engine block heater. The recall technically deals not with the engine block heater itself, but the way it is connected. According to NHTSA campaign No. 19V328000, the engine block heater cord or the terminals that link the cord to the heater could short circuit. A short circuit could potentially damage engine components and result in a fire. According to The Detroit News, 19 fires have been reported but nobody has been injured. GM has yet to figure out a fix, and thus has not yet released a notification schedule for affected customers. If you believe your vehicle is part of the recall, contact GM customer service at 1-586-596-1733 and use reference number N182206310.

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

2017 GMC Acadia adds four-cylinder and All Terrain model

General Motors has officially started the process of updating its long-in-the-tooth fullsize CUVs by unveiling the second-generation GMC Acadia at the 2016 Detroit Auto Show. While the Acadia is 700 pounds lighter, it's also shorter and narrower, which means it's not quite the people mover it used to be. You'll no longer be able to haul eight passengers, although there will still be five-, six-, and seven-passenger offerings. While families might not be thrilled with the loss of a seat, the lighter weight is a net win. Not only will the V6 model feel more powerful and efficient – in addition to the lower curb weight, there's a new, 310-horsepower engine – but it will also likely be more economical. GM estimates the front-drive V6 will return 25 miles per gallon on the freeway, compared to 24 mpg for the current front driver, but city fuel economy remains pegged at 17 mpg. In a move we're not entirely sold on, though, the Acadia will also adopt a four-cylinder engine, and no, it's not GM's highly regarded 2.0-liter turbo. Instead, you'll be able to order this 4,000-pound CUV with a 2.5-liter, 194-horsepower four-cylinder. What it won't be able to provide in straight-line speed, it will make up for with fuel economy. GM is wagering the front-drive, four-cylinder Acadia will net 22 mpg in the city and 28 on the highway. Both engines are paired with a HydraMatic 6T75 six-speed automatic. A new All Terrain model is said to be optimized for wet, snowy and icy conditions, and its drive mode selector removes the Off Road selection in favor of All Terrain. We have live images of both the new Acadia Denali, as well as the new-for-2017 All Terrain model, direct from the floor of the 2016 Detroit Auto Show.
