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).

Recharge Wrap-up: Chevy teases Bolt driving range, China pursues EV subsidy cheaters

Chevy is teasing the Bolt's driving range, which it is set to reveal on Tuesday. It will certainly be able to travel more than 200 miles between charges, but the second and third digits in that value, as it stands today, are still question marks. On its Facebook page, Chevrolet is asking fans to try to guess the official range. Of course, Tesla fans have already started posting their own snide remarks in the comments. Chevy fans are certainly hoping to see the Bolt's range eclipse that of Tesla's upcoming Model 3, which the California-based automaker puts at 215 miles. See Chevy's post on Facebook to make your own guess, or check back there (or here at AutoblogGreen) for the official number once it is unveiled. Fuel cell company PowerCell Sweden says it has signed an agreement with a Chinese company to make range extenders for commercial trucks. The unnamed Chinese customer has placed an order and signed a memorandum of understanding with PowerCell Sweden, and the partners will develop methanol reformer fuel cell range extenders for electric distribution trucks. "Our unique expertise in fuel cells and reformer technology is receiving an increasing attention worldwide and we are truly pleased to get another Chinese order," says PowerCell Sweden Sales Director Andreas Boden.

After the country's Ministry of Finance penalized five companies with fines and, in one case, revocation of production license for subsidy cheats, China has since named 20 more potential violators, including Nissan, Hyundai, JAC, and a subsidiary of BYD. Of the first five companies to be punished under the investigation, Suzhou Gemsea Coach Manufacturing is having its production license revoked, while four others, including a subsidiary of Chery, are being fined for about half of the subsidies received. The scandal is bad new for China's subsidy program, which has helped spur sales of plug-in vehicles. Read more from Fortune, or at Hybrid Cars.

2014 Chevrolet Corvette C7 Convertible offers a few more views before reveal

Over the weekend, Chevrolet released its first images of the new 2014 Corvette Stingray Convertible. Now, ahead of the droptop's official introduction tomorrow at the Geneva Motor Show, the automaker has given us a few more shots of the softop C7 showing off the car's rump albeit from a high, strategically positioned angle.
From this angle, it's hard to get a sense for how long and flat the decklid really is, but we can easily see that, like the rest of the C7's design, the new convertible's decklid and tonneau cover are far more detailed than the current car. We also get a better look at the rear haunches sans brake vents, which have apparently been moved to underneath the car in order to accommodate the top's hard cover.
As for the overall styling of the C7 convertible, with the top erected, we get some idea of what a coupe design (as opposed to the Stingray's fastback shape) would look like on this car. The C5 Corvette most recently had a coupe model that did away with the large glass hatchback, and we recently reported on a low-cost "coupe" model potentially being added to the C7's repertoire.
