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).

New Chevy Small Block crate engine has 405 hp, endless possibilities

With decades of history, the Chevrolet Small Block V8 has definitely stood the test of time, and the company has kept finding ways to make it better. At this year's SEMA Show in November, Chevy Performance is unveiling the latest upgrade to that legacy with the new ZZ6 350-cubic-inch (5.7-liter) crate engine. Offering 405 horsepower and 405 pound-feet of torque, the mill should add a big dose of power to any project car. For the ZZ6, Chevy is working to improve the Small Block's high-rpm performance. To make that happen, the engine has Fast Burn aluminum cylinder heads and an updated valvetrain inspired by the LS family of powerplants. Large intake runners help with the airflow, and the valve springs use a tapered design that allows for less reciprocating mass. The mill also packs a forged steel crankshaft and high-silicon aluminum pistons inside of a cast iron block. Chevy is offering the engine in two versions depending on what the builder needs. The Base configuration comes with an intake, distributor, water pump, and a few other parts but lacks carburetor and accessories. Conversely, the Turn Key option has everything, including the carb, air cleaner, starter, alternator, and more. More details about their availability will be announced at SEMA. NEW ZZ6 CHEVY SMALL BLOCK ADVANCES CRATE ENGINE LEGACY Revised Fast Burn heads with LS-inspired valvetrain enhance high-rpm performance 2015-10-02 DETROIT – Developed with contemporary technologies, including a high-rpm valvetrain, Chevrolet Performance's new ZZ6 crate engine offers builders a modern twist on the classic Chevy Small Block 350. It uses updated Fast Burn cylinder heads with beehive-style valve springs inspired by the LS engine family – a feature that enhances high-rpm capability, enabling the new high-performance engine to achieve 405 horsepower and 405 lb-ft of torque. That's more power than any factory produced 350 engine ever installed in a Chevrolet production vehicle and it's one of the most powerful 350 Small Block-based crate engines in the nearly 27-year history of the "ZZ" lineup. "The new ZZ6 is the ultimate ZZ 350-based crate engine from Chevrolet Performance," said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports.
