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

Hybrid, Plug-in Hybrid and EV Buyer's Guide: Which one do you want?

If you're shopping for a new vehicle these days, there's a litany of acronyms, buzzwords, and technobabble to further complicate an already difficult decision. But if you're looking at a green powertrain, you have three basic choices to compare: hybrid, plug-in hybrid and "EV" or, electric vehicle. So what are they and which one — if any — is right for you? Research your next new vehicle using Autoblog's Car Finder. Gasoline-Electric Hybrids By now, most people are familiar with the concept of a hybrid car. Thank Toyota's Prius for that. At its most basic, a hybrid vehicle has two powertrains, one gasoline and one electric, which work together for maximum efficiency. At low speeds, the engine can shut off entirely, relying solely on the battery for propulsion. The battery is either charged as you drive by converting kinetic energy into potential energy via a complex regenerative braking system, or directly off of the gas motor. This is a very hands-off, behind-the-scenes system as all the driver has to is put in gas and drive as normal. Hybrids come in all shapes and sizes and, according to the EPA, range in fuel economy from 58 mpg for the Hyundai Ioniq Blue all the way down to 13 mpg for the Ferrari LaFerrari Aperta. Best For: Anyone who want to see their fuel consumption go down without many sacrifices. You can easily find a hybrid sedan, hatchback, crossover, SUV or even a pickup truck (i f you can find one). Best of all, a hybrid requires no special equipment to be installed at home, or added work for the driver. Hybrids do cost more than traditionally-powered competitors, so make sure to compare projected fuel savings with how much extra a hybrid will cost – it may take a surprisingly long time to break even. The EPA provides a handy calculator for this very purpose. Our Favorite Hybrids: 2017 Toyota Prius 2018 Hyundai Ioniq Hybrid 2017 Ford Fusion Hybrid Plug-In Hybrids Sometimes referred to as a PHEV, or plug-in hybrid electric vehicle, this is a baby-step towards full electrification. Armed with a much larger battery pack than a hybrid, PHEVs can go between 12 ( Mercedes-Benz GLE550e) and 97 ( BMW i3 w/Range Extender) miles on electricity alone depending on the model and your driving style. Like a normal hybrid, the driver is largely unaware of which power source is currently in use, even as they switch over — either because the battery is drained, or the driving circumstances require more power.

Fingers point to dragged-out NHTSA investigation after second death by ARC airbag inflator

Safety advocates have increased criticism of the federal government's National Highway Traffic Safety Administration after an exploding airbag inflator that's been under investigation for more than six years killed a second person.  On Wednesday, NHTSA posted recall documents filed by General Motors that revealed the second death, the driver of a 2015 Chevrolet Traverse SUV with an inflator made by Tennessee company ARC blew apart, spewing shrapnel. No details were given about where and when the death occurred. NHTSA has said that ARC Automotive of Knoxville has manufactured about 8 million inflators used nationwide in vehicles made by General Motors, Fiat Chrysler (now Stellantis), Kia and Hyundai. “NHTSA should have been all over this along time ago,” said Rosemary Shahan, president of California-based Consumers for Auto Reliability and Safety. “There's just no denying that itÂ’s a (safety) defect.” NHTSA, the agency charged with with keeping America's automobiles and roads safe, began investigating ARC inflators in July of 2015 after two people were injured by flying shrapnel. The investigation became more urgent in 2016, when a Canadian woman driving an older Hyundai Elantra was killed by metal airbag fragments. Public records show only a little progress on the probe. In April, the agency posted a memo in saying it was reviewing volumes of information it received from ARC. Safety advocates such as Shahan say that the dragged-out investigation is an example of the deadly consequences that can result from an understaffed and underfunded agency. The second death should not have happened, Shahan said, and vehicles with faulty ARC inflators should have been recalled faster. The agency, Shahan said, is “grossly underfunded," but it still should have sought recalls of the ARC inflators. She said historically NHTSA has taken little action during Republican administrations but has ramped up safety efforts when Democrats control the White House. Messages were left Wednesday by the Associated Press seeking comment from NHTSA and ARC. At this time, relatively few vehicles are effected. The GM recall covers only 550 Chevy Traverse SUVs from the 2013 through 2017 model years, as well as Buick Enclave SUVs from 2008 through 2017. The automaker said in a statement that the faulty front driver's airbag inflators were either installed at the factory or in replacement airbag modules.
