GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Recalls Chevrolet GM GMC

Silverado HD, Touareg V10 TDI face off in diesel tug-of-war

A couple weeks ago, we watched a Chevrolet Silverado get dominated by a Dodge Ram Heavy Duty in a fullsize pickup tug-of-war, but in that truck's defense, Chevy's Vortec gas engine was no match for the torquey Cummins turbo diesel. For our next round of vehicular tug-of-war, a Duramax-powered Silverado HD takes on Volkswagen Touareg V10 TDI.
Now, on paper, putting the Duramax V8's 365 horsepower and 660 pound-feet of torque up against the V10's 310 hp and 553 lb-ft looks like an easy win for the Bowtie, but unfortunately, this battle has a similar result as the Dodge versus Chevy video, with the Silverado smoking its tires trying to move forward as it gets pulled backwards. Put another way: YouTube 2, Chevy Silverado 0.
It just goes to show, though, that big tires, bolt-on fender flares and goofy smoke stacks don't improve your towing abilities. Besides, what did the Silverado driver expect when the Touareg V10 TDI has towed a Boeing 747 in the past?

LG Chem's troubled Chevy Volt battery plant hiring once again

The Michigan battery plant known for paying its workers to do nothing has turned things around and is now hiring more workers, specifically to do something. South Korea-based LG Chem, which runs the factory to supply the Chevrolet Volt extended-range plug-in vehicle with its lithium-ion batteries, held a job fair recently to bring on 40 new employees in order to meet higher battery demand, according to WZZM, the ABC affiliate for Grand Rapids, MI. The LG Chem factory is in Holland, MI, about 30 miles west of Grand Rapids, and it made its first batteries last year. Prior to that, though, the factory gained notoriety after a US Department of Energy (DOE) probe found that workers there were getting paid to do, well, nothing. That's because demand for the battery packs was so low that it cost less for the plant to sit idle. The DOE was conducting the probe because of its financial grant to LG Chem. But that was then and today is today. LG Chem is looking to ramp up production in advance of the second-generation Volt. That 2016 model-year version is said to have a longer all-electric range and better performance and will ride on a new chassis, but few official details have surfaced. We will know more when we get our first look at the car at the Detroit Auto Show in January.
