GM recalls half-million full-size SUVs to address seatbelt issue

GM is recalling its redesigned full-size SUV models to address improperly riveted mounts securing the third-row seatbelts that may fail in the event of an accident. The population includes the 2021-2022 Cadillac Escalade and Escalade ESV, 2021-2022 Chevrolet Suburban and Tahoe, and 2021-2022 model year GMC Yukon and Yukon XL, for a total of 484,155 vehicles. "Operators at the supplier’s manufacturing plant may have not properly followed manufacturing processes and inadvertently missed the rivet forming operation," GM said in its defect report to NHTSA. "In certain of these vehicles, the rivet that retains the buckle to the mounting bracket in the left or right side third-row seatbelt buckle assembly may not have been properly formed during the manufacturing process. If the third-row seatbelt assembly is not properly riveted, it may not properly restrain occupants in a crash, increasing the risk of injury." Fortunately, the fix is relatively simple. GM service technicians will inspect the rivets on the rear seatbelt buckle assemblies and replace the entire unit if the rivets are not to spec. Dealer notifications have already been distributed; owners should receive notice start in September. Related video: Cadillac Chevrolet GM GMC Ownership Safety SUV

This is what a 2017 Chevy Camaro Z28 could look like

The latest Camaro Z28, the enthusiast darling of the somewhat frumpy fifth-generation pony car, only hit the scene in 2014. It housed the wonderful 7.0-liter, naturally-aspirated LS7 small block V8 and featured a ton of aero bits. The trickest pieces may have been the dynamic spool valve shocks, legitimately race tech for the road. So with the new Camaro out in the wild, we were wondering what a new Z28 might look like, and thus, commissioned these renders based on our best guesses as to what a future Z28 might be. Since Chevy didn't stray too far from the Zeta-chassis Camaro formula with its new Alpha-based car, our vision of a new 2017 Camaro Z28 likewise is a sequel rather than a reboot. The exterior styling and aero details are similar, but sleeker. The defining and protruding front splitter is back, but it's smoothed slightly and better integrated. It shares quad exhaust pipes with the lowlier SS, but they're of the beveled Z06 variety, and sized up to a howitzer caliber. Instead of a weak faux rear fender vent, our version gains a real brake cooling duct. Some iconic elements, like the hood extractor vent and the large decklid spoiler, remain. What we can't see, we have to speculate on. As the track-focused, hardcore pony car in the Camaro lineup, the Z28 will have to do battle with the Ford Shelby Mustang GT350R. There's simply no avoiding it. And whereas Ford distinguished that car with a 5.2-liter, 526-horsepower, flat-plane-crank V8, Chevy is likely to look to the parts bin to find motivation. This isn't a knock; the LS and LT-series small block V8s are both numerous and power-dense. And there's one engine that seems to do the trick: the LSA, last seen in the old CTS-V and still on sale in the Camaro ZL1 (and of course, still being produced as a crate engine). In ZL1 form, the LSA makes about 580 hp, which is a nice margin over the GT350R. It's also a high-zoot but not top-of-the-line mill, having been mostly superseded by the 650-hp LT4. That puts our probable Z28 far enough behind the new CTS-V and current Corvette Z06 in the pecking order to be a safe bet, without hobbling it with the LT1 shared with the Camaro SS and regular Corvette. Will those trick spool-valve shocks from Multimatic make it to the Z28 again? Ford is taking the GT350R very seriously, and if the expensive but supremely capable suspension system is required to manhandle the Shelby at the track, you can bet that Chevy will pony up for it.

GM resumes production of its 3.0-liter turbodiesel straight-six

General Motors temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine in August 2021 due to a supplier shortage. Reports claimed the pause would last through 2021, but the engine is already back in production. Enthusiast website GM Authority learned from sources inside General Motors that the straight-six is once again coming off the assembly line at the Flint Engine Plant in Flint, Michigan. There's no official word on precisely what the problem was linked to and whether it was related to the on-going chip shortage that's wreaking havoc across the automotive industry. All we know is that the pause lasted for about two weeks. Called LM2 internally, the six is available in Chevrolet's Tahoe, Suburban, and Silverado 1500 and in GMC's version of these trucks. It's also an option in the Cadillac Escalade. It develops 277 horsepower at 3,750 rpm and a V8-like 460 pound-feet of torque at 1,500 rpm in every application, and it allows these big behemoths to post surprising fuel economy numbers. Fitted to a rear-wheel-drive Tahoe, the Duramax returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make it more efficient than a Blazer. Demand for the diesel-powered trucks is relatively high. While the shortage undoubtedly took a toll on sales, the Duramax represented 8% of Suburban sales and 6% of Tahoe sales in May 2021. There are no other diesel-burning full-size SUVs available new so they have the market to themselves. On the truck side, Ram still makes the EcoDiesel available on some 1500 trims but Ford abandoned the segment.
