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

2020 Cadillac CT5 debuts at N.Y. Auto Show as a proper sport sedan

The 2019 Cadillac CT5 is here, and it's not a tweener sedan. After having done battle with the luxury sedan world through cars that were either too large or too small, Cadillac is using the CT5 to take direct aim at the BMW 3 Series, Audi A4, Alfa Romeo Giulia and Mercedes C-Class. Specifically, the CT5 replaces the CTS, but takes on vehicles one class smaller than what the CTS did. So, let's take a look at what Cadillac is bringing to the table. To begin, GM knows it has a winner on its hands with the Alpha platform used on the CTS and ATS and the Camaro, so engineers adapted it to the CT5. This seems like a great start, because we all happen to love the driving dynamics from vehicles on this chassis. The wheelbase is a couple inches longer than the CTS, but the CT5 is a couple inches shorter in overall length. As a result, the wheels get pushed toward the corners of the car, leaving the CT5 with relatively short overhangs in the front and rear. It looks different than both of the to-be-discontinued Cadillac sedans, but we wouldn't call it revolutionary. The rear end isn't quite a "sportback," but it's a "faster" shape, eschewing a traditional sedan's long decklid for a sloping-roof look instead. This shape does come at the expense of rear seat headroom, but we'll dive into the interior later. We got a little preview of the powertrain setup before this official reveal, but details were scarce. The base engine is the recently new 2.0-liter turbo four-cylinder found in the Cadillac XT4. Just as it did in that vehicle, this engine makes 237 horsepower and 258 pound-feet of torque. While it might be down on power compared to the old 2.0-liter in the ATS (272 horsepower and 295 pound-feet) we found it to be incredibly smooth, refined and not lacking in thrust compared to the old unit. We're sure the four-pot will offer sufficient power for the CT5, but the 3.0-liter twin-turbo V6 is lying in wait. This engine makes 335 horsepower and 400 pound-feet of torque. Both engines are paired to a 10-speed automatic transmission and can be had in rear-wheel drive or all-wheel drive in every configuration. So yes, you can get the V6 with rear-wheel drive, thankfully. Cylinder deactivation is also equipped to both these power units — the four-banger is able to run on two cylinders, while the V6 drops to four. Cadillac was entirely transparent about its new pumped-in engine sound strategy, too.

2020 Cadillac Escalade spied for the first time

Cadillac is expanding its crossover and SUV range with a new three-row XT6, but that doesn't mean it has forgotten about the one that started it all. As seen in the above photos, the company is testing a new version of the Cadillac Escalade. It's well-covered, but there are a number of details that we can make out. We'll get to what we can see of the design in a bit, but the big news is the suspension. Like the new Tahoe we previously spied, the 2020 Cadillac Escalade will have an independent rear suspension replacing the solid axle set-up that GM's full-size SUVs have always possessed. Its rivals from Ford/Lincoln went independent long ago. We can't underline enough how much of a difference this will make. Handling should be less cumbersome and the ride will be smoother and less prone to jiggling over bumps. It would be improved even further if Cadillac continues to offer magnetically controlled shocks as standard. Inside, the third-row should be positioned lower, thus lowering the current sky-high load height and resulting in a third-row that's actually habitable. In other words, the Escalade won't be so archaic. You can see the visual differences between the new (top) and current (bottom) designs below. Now, as for the design, our best clue to the new Escalade's design is in the grille. The flashy slatted chrome grille of the current model is gone and in its place a more modest mesh grille with little studs pushed to the front. It's very much like the grille found on the new CT6 and XT4. Also, like those two vehicles, the headlights appear to have more horizontal elements than the very vertical examples on the current Escalade. The rest of the SUV is harder to make out. The profile is very similar to the current one, and will surely be shared with the Chevy Tahoe and Suburban and GMC Yukon models. The rear features new rectangular exhaust tips nestled into the rear bumper. The taillights will likely continue to stretch up the rear pillars. Like the suspension, the Escalade will continue to be generally mechanically the same as the aforementioned Chevy and GMC versions, albeit with the best parts standard. The updated 6.2-liter V8 with Dynamic Fuel Management first introduced on the Silverado and Sierra will likely be the standard engine. It will then be paired with the 10-speed automatic transmission. With the new Navigator so widely impressing in reviews and in sales, this new Cadillac Escalade will have to step it up.
