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).

Mystery Cadillac Escalade prototype spied testing on public roads

This mystery Cadillac Escalade prototype could be a rumored V model featuring a supercharged LT4 V8. This prototype, sporting a fancy exhaust and other unique elements under fairly elaborate camouflage, was spied testing on public roads in Michigan.  Since it's still quite comprehensively disguised, we can't say much for certain about what this prototype has going on underneath. We can see a new set of wheels, a quad-tip exhaust and what appears to be a redesigned lower front bumper, but our spies didn't indicate anything else definitive — not even the telltale whine of a supercharger. That seems a glaring omission, given that a V model would almost certainly be powered by the same supercharged V8 found in the CT5-V Blackwing, where it is expected to develop well north of 650 horsepower.  Cadillac chief engineer Tony Roma has previously suggested that more V-badged cars are in the pipeline without confirming which ones or when to expect them. An unverified report published in February 2021 claims the Escalade's 6.2-liter V8 will soon receive a 200-horsepower bump thanks to a factory-backed, dealer-installed supercharger; a full-fledged V model would take that formula a step further. If you're not familiar with Cadillac's latest performance offerings, "V" models are now the mid-range performance variants, similar to Audi's "S" cars in that they offer a bump in power and handling but stop short of being full-blown track monsters. That treatment is reserved for the new "Blackwing" nameplate, which was derived from the twin-turbocharged V8 of that same name that was originally slated to power those range-topping models.  Related video:

Combine a self-driving car with V2V, and here's what happens

Transportation engineers have started laying the groundwork for a traffic world in which cars communicate with other cars and infrastructure like bridges and traffic lights. How about an environment in which cars talk to pretty much everything and everyone? In a preview of its offerings at the upcoming Consumer Electronics Show, Delphi Automotive will deploy just such a concept. Engineers have designed a system that communicates with traffic signals, street signs, pedestrians, cyclists, even to fry pits and parking garages along a driver's route. To date, engineers and researchers across the auto industry have focused on the technical and safety-oriented foundation of future vehicle-to-vehicle communications, which could help cars share information about everything from traffic tie-ups to upcoming road hazards. Beyond those building blocks, many have projected that V2V could also include more consumer-focused features. Delphi's system, dubbed V2Everything, might be the first that combines those sorts of features in a tangible package. At CES in Las Vegas, scheduled to begin the first week of January, company officials say they'll demonstrate in real-world conditions how V2V technology can be used in an autonomous vehicle to provide a range of critical safety information and leisure and convenience options for riders. The first V2V technology installed on a production car is slated to appear on the 2017 Cadillac CTS. "We imagine a world with zero traffic accidents," said Jeff Owens, Delphi's chief technology officer. "To get there, we will need a convergence of active safety, sensor fusion, connectivity platforms and advanced software." Such software might allow a vehicle to start searching for and reserving parking spots at a programmed destination long before arriving. It could allow riders to place their McDonald's drive-through order from the road and have the food ready for pickup along the route. For the drive itself, the Delphi-equipped car can stay updated on the status of traffic lights around Las Vegas, and can anticipate yellow and red lights. Using smart-phone technology, the car can detect pedestrians and cyclists that may otherwise be hard to see. It can send messages to friends or family to notify them of a driver's location. Some of those features have been available on third-party apps or individually developed by automakers. But this system marries them together in a single system that is tailored for use in self-driving cars.
