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).

Cadillac is building an LMDh car, will compete in WEC and Le Mans

Cadillac returned to sports car racing back in 2017 with its DPi race car, and it has had a successful run with it. It won four Rolex 24 Hour races at Daytona from 2017 to 2020, and took home two championships. So it's not totally surprising that it will continue running in the IMSA series with a new LMDh-class car. But that also means that Cadillac can, and will, race in the World Endurance Championship series, which includes the 24 Hours of Le Mans. This is because LMDh is a class that will be legal in both IMSA and WEC racing, as will the LMH hypercar class. So Cadillac will be taking on hypercars from Toyota, Peugeot and Glickenhaus. Audi and Porsche have announced plans to run LMDh racecars as well, so it will be a crowded field. There have even been rumors of a Dodge-badged version of the Peugeot 9x8 LMH car as well as a Lamborghini LMDh entry. Per LMDh rules, the car will feature a spec chassis and hybrid unit, but the engine and bodywork will be unique to the Cadillac. Unlike LMH, there are no requirements to build road-going versions, so we sadly won't see a wild mid-engine Cadillac hybrid supercar on the streets (unless Cadillac just decides to build one; don't hold your breath). But we'll still be excited to see another American manufacturer compete for an overall win at Le Mans. Cadillac will team up with Dallara, Chip Ganassi Racing and Action Express Racing for vehicle development and competition. The car will make its racing debut at the 2023 Rolex 24 at Daytona in January of that year. All we have to go on for the car's looks is the rendering at the top, which suggests a seriously angular shape. It will also be called the LMDh-V.R, similar to the current DPi-V.R racecar.
