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 looks to combat high theft rates on SUVs with added tech

The Cadillac Escalade has been at or near the top of most-stolen and insurance-loss lists for more than seven years, until it dropped to number six earlier this year. In 2011 it was fitted with a host of new security features to address its easy-to-override features and that has brought the number of thefts down, but when eight of the ten most stolen rides are large SUVs from General Motors, no one will argue that something else needs to be done.
Thus, GM has fitted this same theft-deterring tech to the 2015 Suburban, Tahoe and Yukon. The Suburban and Tahoe will get the steering lock that the Escalade and Yukon already get, plus bolted-down third-row seats to deter thefts like this, stronger door lock cylinders and shields, and side-cut keys to inhibit picking.
Additional security measures in a Theft Protection Package can be purchased for $395, consisting of sensors on the greenhouse glass and interior, an incline/tilt sensor and added "key control systems" to make it more difficult for the men in black balaclavas to steal what you bought.

Fernando Alonso sputters in his Indy test

INDIANAPOLIS — Helio Castroneves and Fernando Alonso kept waiting around Wednesday. Now both international stars have some unfinished business to take care before qualifying for this year's Indianapolis 500. After enduring a rain delay of more than four hours then watching IndyCar regulars turn laps at Indianapolis Motor Speedway for two more hours, Castroneves and Alonso finally made it onto the track — but couldn't quite complete their refresher course. "Happy to be back here because this place is great," Alonso said after posting a fast lap of 218.690 mph — the slowest of the nine-driver evening session. "We were slow because the weather and some of the decisions people made on running time and things like that." He faced a bevy of problems in his first trip back to Indy since an impressive rookie performance in 2017. The rain delay forced organizers into rescheduling the one-day test, moving the rookie and refresher driver time from midday to the evening, cutting a significant amount of practice time for Alonso and the others. And when the green flag finally waved, Alonso's No. 66 car stalled in the warmup lane forcing the two-time Formula One champion from Spain to be towed back to pit lane where his crew worked feverishly to fix an electrical problem while sat in the cockpit. Eventually, he did get out and passed the first of two refresher phases. He'll have to wait until opening practice of the 500 on May 14 to pass the second. "It was frustrating for everyone because it was a brand new chassis and a brand new car, so we expected to run a lot," said Alonso, who drives for McLaren Racing. "If we could have had this at midday, you could work on your issues in the afternoon and then go out again." To put his day in perspective, Takuma Sato, the 2017 Indy winner from Japan, posted the fastest lap of the day at 226.993 mph and Colton Herta was the fastest rookie at 226.108. Castroneves, as usual, was good right from the start and posted a fast lap of 225.565. The three-time Indianapolis 500 winner looked smooth and fast on his favorite track and wasted no time passing the first phase. That much should have been expected from the popular Brazilian, who has recorded seven top-three finishes in 18 Indy starts and will make his season debut May 11 in the IndyCar Grand Prix. The weather and yellow flags prevented four of the five veterans — Castroneves, Alonso, Oriol Servia and JR Hildebrand — from passing phase two. Only Indy native Conor Daly made it.
