NHTSA investigating nearly 750,000 GM models over non-deploying airbags

Nearly 750,000 vehicles built by Chevrolet, GMC, and Cadillac are the subject of a National Highway Traffic Safety Administration (NHTSA) investigation due to non-deploying driver-side airbags. While the investigation is ongoing, the agency believes the issue is likely due to rust particles that form on the inflator's connection terminal interface. The list of nameplates included in the investigation includes Chevrolet's Silverado, Tahoe, and Suburban, GMC's Sierra, Yukon, and Yukon XL, plus Cadillac's Escalade, Escalade ESV, CT4, CT5, and XT4. All of the potentially affected vehicles are 2020 or 2021 models, according to a bulletin published on the NHTSA's website. Investigators launched the probe in April 2021 after 15 consumers reported airbag-related issues, including nine who said an airbag malfunction light appeared in the instrument cluster. More alarmingly, the NHTSA is aware of six accidents that caused significant damage to the car's front end yet didn't trigger the driver's airbag. It adds that there are no fatalities linked to the issue, but there are six crashes and eight injuries reportedly blamed on it. No evidence suggests this problem is related to the millions of potentially deadly Takata inflators recalled over the past few years. General Motors is aware of the defect. It sent a technical service bulletin (TSB) to its dealers in March 2021 to address the aforementioned warning light. The note explains the issue is due to "rust particles in the connection terminal interface of the driver's airbag inflator." The company hasn't issued a safety recall yet, however. Whether it will partially depends on the NHTSA's findings. It's currently looking into the scope and the severity of the problem, and it wants to understand its implications on driver safety. Investigators will decide whether General Motors needs to recall the 749,312 cars that are part of the probe when they close their investigation. General Motors has already spent a significant amount of money replacing defective airbag-related parts in its cars. In November 2020, it was ordered by the American government to recall nearly 6 million pickup trucks and SUVs equipped with potentially dangerous Takata airbag inflators. It repeatedly argued that testing proved the inflators were safe, and it petitioned the agency four times starting in 2016 to avoid a recall, which cost an estimated $1.2 billion (about a third of its net income in 2020).

2022 GMC Sierra 1500 Denali interior spied with dramatic redesign

The 2022 GMC Sierra’s interior overhaul is coming into better view with these new spy shots revealing a totally new dash.  GMC teased out a few changes when it announced Super Cruise was coming to the 2022 Sierra, but only so much was visible in the tightly cropped photo. These spy shots tell a fuller story about whatÂ’s going on inside the new GMC pickup. WeÂ’re instantly drawn to the new center stack that doesnÂ’t even remotely look like the truckÂ’s current design. ThereÂ’s a new widescreen infotainment system integrated nicely into the dash just below new thin air vents. It appears to be running a version of Android Automotive. The Google Assistant bubble is visible in the top left corner, and a Google sign-in screen is showing on the far right. GMC is obviously still prioritizing hard buttons and knobs for all vital controls. A big, knurled-looking volume knob is positioned to the left of the screen. And the climate control layout is all buttons and knobs with glossy black and chrome accents. This, along with the angled surfaces, classes it up a bit versus the current sea of flat black center stack buttons. Even the push button start appears dressed up in chrome. One other large change to the center console area is the introduction of a gear lever replacing the column-mounted shifter. The new shifter looks slathered in leather, glossy plastic and chrome accents. ThereÂ’s a part of us that will miss the chunky truck-like operation of the column-mounted shifter, but this new design is certainly more befitting of a luxury pickup. And from what we can tell, this Sierra is the luxury-oriented Denali trim. Its exterior features give it away with the ostentatious grille treatment and chrome trim scattered about. We still donÂ’t know which, if any, of these features we see here will be exclusive to the Denali, but the digital instrument cluster seems like a given but will likely be available further down the trim tree. This replaces the truckÂ’s current, tired-looking gauges with a vibrant and neatly-integrated screen. Super Cruise, as it is throughout the lineup of GM cars that offer it, also looks optional — this Denali does not have the fancy light-up steering wheel or controls for it. ItÂ’s worth noting that this DenaliÂ’s interior could be different than the rest of the Sierra lineup. GM already did that with the redesigned Yukon, giving its top trim model a different look than the rest of the trims.

Redesigned 2021 GMC Yukon gets a diesel, AT4 model, Denali-exclusive interior

GMC's most robust family hauler is getting a complete redesign for the 2021 model year, including a new, off-road centric AT4 model, an upscale interior exclusive to its luxurious Denali model, an available air suspension, and, last but not least, a diesel engine.  With Americans obsessing over trucks, it's no surprise that GMC is going hard with its AT4s-for-everybody strategy; the Yukon is no exception. This will be the first model year for the new trim on GMC's largest SUV. This off-road model gets all the goodies you'll need to veer off the beaten path with confidence, including an extra 2.0 inches of ground clearance with the adaptive suspension option (more below), a two-speed transfer case, standard Goodyear all-terrain tires, an off-road mode for GMC's "Traction Select" drive mode system, hill descent control, and some extra underbody skid plates. Since GMC is a premium brand, even the AT4 gets some luxury appointments, such as a heated steering wheel, heated and ventilated front seats, and heated outboard second-row seats. The interior is also adorned in black leather with tan accents and "AT4" embroidery in the seat backs.  Speaking of premium, GMC will introduce an air-ride adaptive suspension with an off-road ground clearance mode as a late-availability option for several Yukon models, and this feature will be included on the Denali trim.  The Yukon and Yukon XL are GMC's variants of Chevrolet's full-sized SUVs, the Tahoe and Suburban. Their fundamental body-on-frame architecture is also shared with GM's half-ton pickup trucks, and thanks to that common engineering, they can also share powertrains. That's normally just a trivial side note when it comes to a new GM SUV announcement, but this time around, it's a bit more meaningful thanks to the introduction of a new light-duty, inline-six diesel in GM's truck lineup last year.  Yep, that means that for 2021, like the Tahoe and Suburban, the Yukon is getting a diesel option. The 3.0-liter Duramax makes the same 277 horsepower and 460 pound-feet of torque as it does in GM's trucks.  GMC's standard engine is still the 5.3-liter V8 that makes 355 hp and 383 lb-ft of torque. The 6.2-liter V8 is also an option like before, producing 420 hp and 460 lb-ft of torque. All engines come with a 10-speed automatic and a choice of rear- and four-wheel drive.
