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

Super Cruise will make 2018 Cadillac CT6 semi-autonomous

General Motors has been working on its semi-autonomous driving system for years. Called Super Cruise, it had initially been slated for a fall 2016 debut. Of course, something as critical to safety as a self-driving system should ideally have the bugs worked out before putting it in the hands of customers, and the launch date had to be pushed back. It appears that Super Cruise is road-ready now, as Cadillac has announced the system will be available in the 2018 CT6 sedan when it goes on sale this fall. Super Cruise offers hands-free driving on the highway, taking control of steering and speed under the supervision of the driver. An attention detection system – a camera and infrared lights that track head position – ensures that the driver is paying attention and is available to take over driving responsibilities. If needed, Super Cruise will initiate a series of nags, including a flashing light bar on the steering wheel, to regain the driver's attention. If the driver is unresponsive, the system can bring the car to a safe stop and use OnStar to call first responders. The system employs a suite of sensors, cameras, and GPS, as well as precision lidar-scanned map database, to place the car where it needs to be on the road and in the center of its lane. It only works if the sensors detect appropriate road conditions, and is limited to the more predictable terrain of divided highways with on- and off-ramps. Yes, it's limited, but safety is paramount, and drivers who spend a lot of time on the highway will appreciate the convenience nonetheless. Related Video:

Remembering Pierre Cardin's automotive legacy

Pierre Cardin has passed away at age 98, and while the designer had a great impact on the world of fashion, he also brought his signature style to the automotive realm, chiefly with the unlikely partner of American Motors. At the dawn of the 1970s, AMC decided to seek out a little glamour for its freshly renewed product lineup by having famous fashion designers work their magic on AMC cars. The first model to get the fashion treatment was the Hornet Sportabout wagon, with a special Gucci edition that became available for 1972. Later that same year, Pierre Cardin's Javelin was introduced. The Cardin Javelin arrived midway through the '72 model year as an interior option package. The designer had submitted as many as 10 proposals to AMC, and the chosen selection was a black interior with a wild multi-hued stripe of silver, white, red and purple that grooved across the seats, touched the door panels and continued onto the headliner. "People should feel like they're sitting in a living room rather than a machine," the designer was quoted in ads introducing his eponymous Javelin. In a press release, AMC said, "Cardin takes an ultra-modern abstract approach to his interior design." The Cardin interior option package was available with specific exterior colors: Snow White, Stardust Silver, Trans Am Red, and Wild Plum. For the '73 model year, Diamond Blue was a new exterior color option. The Pierre Cardin option was only $85 and was offered exclusively on the Javelin SST, although it's reported that the Pierre Cardin option also appeared on a handful of Javelin AMX models. For 1973, you could officially get a Pierre Cardin Javelin AMX. A total of 4,152 were built over the two model years. AMC's next fashion special was the Matador coupe, but the automaker tapped Oleg Cassini for that gig. Pierre Cardin was not finished with the automobile business, though. In 1975, he put his touch on the Sbarro Stash, an obscure supercar based on the SV1, with the result displayed at the Paris auto show. The designer next customized a run of early-'80s Cadillac Eldorados, and this time the treatment extended beyond the interior. A redesigned front end featured hidden headlights behind a full-width horizontal-car grille but unfortunately made the already-considerable front overhang even longer; the rear treatment was similarly modified with the factory vertical taillights replaced with horizontal units.
