400,000 Chevy, GMC pickups recalled: Side airbags can explode

DETROIT — General Motors is recalling more than 400,000 pickup trucks in the U.S. because the side airbags can explode without warning and spew parts into the cabin. The recall covers certain 2015 and 2016 Chevrolet Silverado and GMC Sierra 1500, 2500, and 3500 trucks. Documents posted Friday by U.S. safety regulators say the airbag inflator can rupture or the end cap can fly off on both sides of the trucks. Documents say three inflators ruptured in 2015 Silverados last month, one in Florida and two in Texas. All three trucks were unoccupied at the time, and GM says it has no reports of injuries. Dealers will replace both side airbag modules. The company says it has a limited number of replacement parts available. Owners will be notified starting Aug. 16 and they'll get a second letter when parts are widely available. About 9,000 of the trucks were recalled last year for the same problem. The company says a manufacturing defect allowed moisture into the inflator while it was being manufactured, causing corrosion. The inflators were made in Mexico by Joyson Safety Systems, the company that took over Takata. Back in April, Silverado and Sierra were among nearly 750,000 GM vehicles in a National Highway Traffic Safety Administration (NHTSA) investigation into non-deploying driver-side airbags. That investigation is ongoing. Takata is responsible for the largest recalls in automotive history, covering about 100 million inflators among 19 major automakers worldwide, including about 67 million inflators in the United States. Nineteen deaths in the U.S. have been attributed to Takata inflators. Only about 50 million of the 67 million recalled inflators in the U.S. have been repaired. This latest recall is a good reminder to go to NHTSA's recalls website and enter your car's VIN. Millions of recalled vehicles still pose a danger to their owners. Yours could be one of them.   Recalls Chevrolet GM GMC airbag Takata airbag recall

Here's how the EcoCAR 3 teams are going to green up their Camaros

Plug-in hybrids were probably not what the Dead Milkmen had in mind when they wrote their 1985 alt-punk classic Bitchin' Camaro (OK, we're not really sure what they had in mind), but we're certainly fans of the effort. The 16 college teams competing in the third version of the EcoCAR green-vehicle contest have declared which powertrains they will attempt to build for maximum environmental friendliness. They'll be working with 2016 Chevrolet Camaros that General Motors is donating to the competition. The US Department of Energy is also helping to fund the competition. Out of the 16, all but one will go with a plug-in hybrid powertrain which switches over from electric power to an engine powered by E85 (i.e., an 85-percent ethanol blend) when the juice runs out. Those schools include the University of Alabama, Arizona State, Mississippi State, Ohio State and Penn State. The lone dissenter is the team from the University of Tennessee, which is going with a hybrid vehicle powered by E10. This past spring, Ohio State was named winner of Year One of EcoCAR3, winning $10,000 in the process. THE Ohio State University (as students and alumni like to call it) also won the overall competition for EcoCAR 2 last year. The vehicle used in that project was a 2013 Chevrolet Malibu, and OSU also used a plug-in hybrid/E85 combo to take the big prize. Take a look at the list of schools and their powertrains of choice for EcoCAR 3 here. Related Video:

Next Chevy Silverado could get this built-in tailgate step

General Motors just received patent approval for a tailgate step in a pickup bed. And given the timing, don't be surprised if you see this on the upcoming 2019 Silverado pickup (not the mention its GMC Sierra twin), expected to arrive in late 2018. According to the patent, granted in December of last year, the whole mechanism is housed in the tailgate assemble. The magic happens when a portion of the top half of the tailgate swings down and a step folds out. There's also a handle that locks into position to help climb up into the bed. As trucks get bigger and taller over the years, it gets harder and harder to access the cargo bed. Ford's solution with the 2009 F-150 was a step that slides out from the end of the tailgate. Back then, Chevy made an ill-advised ad highlighting the feature for Ford. And while Howie Long mocked the F-150's "man step" Ford saw almost a third of its trucks with the option in the first year. The GM design seems to improve on Ford's idea as it appears to be wider and has a back to the lower step. That is, you don't have to worry about stepping through the ladder-rung design as on the F-150. Ford's tailgate step later spread to the F Super Duty, and other cargo access assists have proliferated through the truck world. On the most recent redesign, the Chevrolet Silverado took a trick from the Avalanche and added cutouts to the corners of the rear bumper that act as a foothold. Ford also offers a deployable side step, Chevrolet has running boards that scoot rearward with a kick of the boot, and Ram offers fixed wheel-to-wheel side rails. Nissan is in on the game too, with an optional folding step that tucks under the rear bumper. We don't expect Chevrolet to comment on when or if we'll see this feature in the showrooms. But given that engineers are already hard at work on the next Silverado and the timing of this patent lines right up with the new truck's development cycle, we'll be disappointed if this patent stays in the file cabinet.
