2021 Chevy Silverado, GMC Sierra fuel economy to go down due to global chip shortage

Production of the 2021 Chevy Silverado and 2021 GMC Sierra is continuing, but the global semiconductor chip shortage is resulting in a mid-year change. Or rather, an omission.  Basically, the availability of cylinder deactivation for the 5.3-liter V8 will be significantly reduced, resulting in a reduction of 1 mpg combined for affected models. This applies whether that engine has the six- or eight-speed automatic, as well as to both the regular Active Fuel Management and the more advanced Dynamic Fuel Management cylinder deactivation systems. DFM does remain with the pairing of 5.3-liter V8 and 10-speed automatic that comes standard on the LT Trail Boss and High Country. "Due to the micro controller shortage, the components that control AFM/DFM in the engine control module (ECM) have been removed," GM spokesperson Michelle Malcho told Autoblog. She also indicated that the engines will still have the AFM/DFM hardware in place, but that GM will not allow activation of the systems in the future with an ECM change.  Malcho also confirmed to Autoblog that the Silverado and Sierra's other engines will continue to have AFM and DFM, including the 2.7-liter turbo inline-four, 4.3-liter V6 and 6.2-liter V8. In an earlier statement to Reuters, she declined to say the volume of vehicles affected. "By taking this measure, we are better able to meet the strong customer and dealer demand for our full-size trucks as the industry continues to rebound and strengthen," Malcho wrote Reuters in an email. The change runs through the 2021 model year, she said. Malcho told Reuters it would not have a major impact on the Detroit automaker's U.S. corporate average fuel economy (CAFE) numbers. "We routinely monitor our fleet for compliance in the U.S. and Canada, and we balance our portfolio in a way that enables us to manage unforeseeable circumstances like this without compromising our overall (greenhouse gas) and fuel economy compliance," she said. GM's fleetwide fuel economy in the 2018 model year was 22.5 miles per gallon and was projected to rise to 22.8 mpg for 2019, according to a report by the Environmental Protection Agency. To meet federal CAFE requirements, automakers like GM often use credits from either earlier years where they faced less stringent rules and performed better than the requirements or buy credits from other automakers. GM said last month the chip shortage could shave up to $2 billion from this year's earnings.

Chevy Colorado gets box delete option designed for upfitters

The Colorado, which marks the return of Chevrolet to the midsize truck segment, is receiving critical praise, and now it's time for the pickup to get to work. At the National Truck Equipment Association Work Truck Show in Indianapolis, IN, Chevy is unveiling a box delete option package for the model that allows businesses to custom tailor the Colorado to their needs. The choice to remove the bed is exclusively available on the Colorado Work Truck trim in the rear-wheel drive, extended cab model with a 305-horsepower, 3.6-liter V6 and six-speed automatic gearbox, and Chevy claims this is the only option of its type in the segment. Beyond the obvious loss of the rear, these trucks feature eight mounting points on the frame for upfitters to install any necessary modifications. They also get the Z82 trailering package and a locking differential. The versions with the box delete package carry a payload rating of 2,200 pounds an a gross vehicle weight rating of 6,001 pounds. "It's ideal for utility companies requiring service bodies, as well as landscapers and other businesses needing the utility of a flatbed," Ed Peper, US Vice President for General Motors Fleet and Commerical, said in the option's announcement. Further options with the package are limited to choosing a repositioned fuel filler for the upfitter to install and deleting the rear seat for extra interior capacity. The box delete becomes available in mid-April, and buyers get a $300 credit off the price of the Colorado when it's selected. Colorado 'Box Delete' Expands Options for Businesses Chevrolet package offers unique midsize pickup platform for alternative uses 2015-03-04 INDIANAPOLIS – With a box delete option, business owners and fleet managers can have it their way when it comes to customizing the back end of the 2015 Chevrolet Colorado. Chevrolet today announced availability of the package in mid-April. It is on display this week at the annual National Truck Equipment Association Work Truck Show in Indianapolis. It is the only such option offered in the midsize truck segment. "With the segment-leading efficiency and maneuverable size, the Colorado makes a great, flexible choice for urban businesses and fleets to make the most of a midsize truck," said Ed Peper, U.S. vice president, GM Fleet & Commercial.

GM announces 3 new recalls affecting 1.7M vehicles in North America [w/video]

Still embroiled in the ongoing ignition switch recall, General Motors announced today three more discrete recalls, affecting a grand total of 1,546,900 vehicles in the US. The Detroit News reports that some 1.7 million vehicles are affected overall in North America. The first and largest of the trio of new recalls concerns some 1.18-million Buick Enclave and GMC Acadia crossovers from the 2008-2013 model years, Chevrolet Traverse from 2009-2013 (pictured above) and Saturn Outlook vehicles from 2008-2010. All of the crossover utilities may have an issue with the wiring harness for their seat-mounted side airbags. Apparently, the vehicles are equipped with a Service Air Bag warning light that, if ignored, "will eventually result in the non-deployment of the side impact restraints." Those restraints include the side airbags, a front-center airbag if the vehicle is so equipped and seatbelt pretensioners. Dealers of affected vehicles will be instructed to remove driver and passenger side airbag wiring harness connectors, and then "splice and solder the wires together." The second recall affects 303,000 Chevrolet Express (pictured right) and GMC Savana vans from model years 2009-2014, and with gross vehicle weights under 10,000 pounds. Said vehicles do not comply with a head impact requirement for unrestrained occupants, and will need a reworking of the instrument panel material to be sent back on the road. It doesn't sound as though there's a quick fix for this one, as the GM press release states: "Unsold vehicles have been placed on a stop delivery until development of the solution has been completed and parts are available." Finally, the third recall affects 63,900 Cadillac XTS luxury sedans from model years 2013 and 2014. A brake booster pump may be susceptible to corrosion by way of the relay, potentially causing and electrical short, overheating, melting of plastic components and even engine fires. GM says it is aware of two engine fires in unsold XTS models and two cases of melted parts. Repairs for the issues affecting the XTS have not not mentioned by GM in the release. The Detroit News is also reporting that along with news of the triple-recall, GM is taking a $300-million credit to help pay for the repair costs, and to deal with the ongoing costs associated with the ignition switch recall. In an attempt to explain just what GM has been doing in the face of these very serious issues, newly minted CEO Mary Barra has addressed the issues in a new video.
