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).

GM to idle Indiana truck plant for two weeks over chip shortage

WASHINGTON —General Motors said Friday it will idle for two weeks in April an assembly plant in Indiana that builds pickup trucks, over ongoing semiconductor chip shortages. The Detroit automaker said it will halt production at its Fort Wayne assembly plant, which builds the Chevrolet Silverado 1500 and GMC Sierra 1500, for two weeks starting April 4. "There is still uncertainty and unpredictability in the semiconductor supply base, and we are actively working with our suppliers to mitigate potential issues moving forward," GM said Friday. The automaker said this is its first semiconductor-related full-size truck production downtime since August. GM noted that overall it has "seen better consistency in semiconductor supply through the first quarter compared to last year as a whole. This has translated into improvement in our production and deliveries during the first three months of the year." GM Chief Executive Officer Mary Barra met with some lawmakers on Capitol Hill this week, including Republican Senator Todd Young of Indiana. GM is backing a bill in Congress to provide $52 billion in government subsidies to boost U.S. semiconductor manufacturing. GM said that legislation could help "alleviate the ongoing shortage that continues to impact U.S. automotive manufacturing." (Reporting by David Shepardson; editing by Jonathan Oatis) Related video:

GM puts 3 million miles on hydrogen fuel cell test fleet

Have General Motors' hydrogen fuel-cell vehicles emitted enough water vapor over the past six-plus years to equal the steam coming out of Old Faithful? Not exactly, but GM has released a few figures related to the Project Driveway initiative it began in 2007. The numbers are impressive, if not quite of the geyser-spouting variety. In all, the General converted 119 Chevrolet Equinox SUVs to run on hydrogen, and those vehicles have just collectively surpassed the 3 million mile mark. And if you were waiting for us to tell you that the distance equals a half-dozen round trips between the earth and the moon, well, there you go. The better news is that the SUVs have combined to save almost 158,000 gallons worth of gas, and some of the vehicles have more than 120,000 miles on them. More than 5,000 drivers have participated in the project. GM reached that landmark about 10 months after it announced that it was working with Honda to accelerate the development of hydrogen fuel-cell powertrain technology. The two companies estimated last summer that it may have something to sell to the public as soon as 2020. For now, you can check out General Motors' press release below. GM Fuel Cell Fleet Tops 3 Million Miles Chevrolet Equinox fuel cell vehicles driven in real world reach milestone DETROIT – General Motors' fleet of fuel cell vehicles recently passed 3 million miles of hydrogen-powered, real-world driving. Some individual vehicles have accumulated more than 120,000 miles. By GM's estimate, using hydrogen to power these vehicles, the fleet has avoided 157,894 gallons of gasoline consumption. This specially equipped fleet of Chevrolet Equinox Fuel Cell vehicles are part of GM's 119-vehicle Project Driveway program, which launched in 2007. Since then, more than 5,000 drivers have provided feedback on the functionality and drivability of fuel cell technology. "Hydrogen fuel cell technology is an important part of GM's advanced propulsion portfolio and we continue to make substantial progress in furthering this technology," said Charlie Freese, executive director of GM's global fuel cell engineering activities. "These vehicles have operated through seven full winters and a wide range of environmental conditions, proving that fuel cells can meet the demands of real-world drivers." Last year, GM announced two fuel cell-related collaborations.
