GM recalls nearly 1 million vehicles for airbag defect

WASHINGTON — General Motors said on Friday it will recall nearly 1 million sport utility vehicles in the United States because the driver's airbag inflator may explode during deployment. The recall covers 994,763 Buick Enclave, Chevrolet Traverse, and GMC Acadia vehicles from the 2014 through 2017 model years with modules produced by ARC Automotive Inc. Dealers will replace the driver's airbag module. The National Highway Traffic Safety Administration said a driver in Michigan of a 2017 Chevrolet Traverse was in a crash in which the front-driver airbag inflator ruptured during deployment causing facial injuries. An April 25 inspection confirmed that the front driver airbag inflator ruptured in the vehicle. The National Highway Traffic Safety Administration (NHTSA) demanded the recall of 67 million air bag inflators because it believes there is a safety defect, but auto supplier ARC Automotive Inc rejected the U.S. regulator's request, documents released on Friday show. The auto safety agency said the inflators pose an unreasonable risk of death or injury. Even as ruptures mount, "ARC has not made a defect determination that would require a recall of this population," NHTSA said in its demand letter to the Tennessee-based company. "Air bag inflators that project metal fragments into vehicle occupants, rather than properly inflating the attached air bag, create an unreasonable risk of death and injury." GM said it was still investigating the issue with the assistance of a third-party engineering firm. "GM is taking this expanded field action out of an abundance of caution and with the safety of our customers as our highest priority," the Detroit automaker said. GM said it was aware of two prior ruptures of ARC-manufactured airbag inflators in 2015 Chevrolet Traverse vehicles, and GM conducted two earlier small recalls of about 3,000 ARC inflators. All three rupture events in Chevrolet Traverse vehicles involved the same inflator variant. ARC noted in a letter made public Friday that no root cause for those ruptures has been identified by ARC or GM. ARC said it was assessing the scope of GMÂ’s recall.  Government/Legal Recalls Buick Chevrolet GMC Safety Crossover SUV

2013 Chevy COPO Camaro announced with two new engines and manual option

Chevrolet is following up the 2012 COPO Camaro with another limited run of the drag-strip-ready production car for 2013. Ditching the superchargers, the 2013 COPO Camaro can only be equipped with one of three naturally aspirated V8 engines, and other new features include the option of a manual transmission, new front springs, some minor styling changes and a lower starting price of $86,000. All cars are designed to abide by the rules of the NHRA's Stock Eliminator or Super Stock classifications, depending on in which series buyers wish to enter their Chevrolet Camaro.
Returning for 2013 is the 427-cubic-inch V8 producing 425 horsepower, but the new engines include a 325-hp 350-CID V8 and a 375-hp 396-CID V8. Buyers can select to purchase all three engines, and each will be matched with the sequence number of that car; the track-only COPO cars will not have vehicle identification numbers and can't be registered for street use.
Chevrolet is also offering unique enthusiast-specific options such as a COPO Build Book and the opportunity for owners to help assemble their car's engine at the Chevrolet Performance Build Center in Wixom, MI.

How easy is it to rebuild a Chevy small block V8?

Chevrolet's famous small block V8 stands as one of the workhorse engines in American auto history, with its variants going into vehicles from hot rods to pickup trucks. But do you know that you can fully disassemble and completely restore one of these mills in just under four minutes? Well, as long as there's some assistance from time-lapse photography, that is. Hagerty created this short clip showing a dirt-covered small block turning from a frog into a prince. Thankfully, the time-lapse doesn't speed the process up too much, and it's still easy to see how all of the principal parts fit together. With all sorts of sensors and software helping to drive the modern automobile, viewing the internal combustion engine in its purely mechanical form is still fascinating. Related Video:
