NHTSA closes 4-year GM investigation, issues common sense advisory [w/video]

Since January 2011, the National Highway Traffic Safety Administration has been investigating a possible problem with corroding brake lines in General Motors' GMT800-platform models, like the Chevrolet Silverado and Suburban and GMC Sierra, in states with salt on their roads in the winter. However, as opposed to launching a full recall of millions of vehicles, the government is issuing a common-sense safety advisory to all drivers in snowy states to keep their vehicle's undercarriage clean. It even has a video explaining things. "Older-model vehicles, often driven in harsh conditions, are subject to corrosion over long periods of time, and we need owners to be vigilant about ensuring they, their passengers, and others on the roads are safe," said NHTSA Administrator Mark Rosekind in the announcement of the end of the investigation. The agency was clear in its report that "brake line corrosion seen in the GM vehicles was not unique," and the government "has not identified a defect that would initiate a recall order." Instead NHTSA is advising drivers, especially those of vehicles from before 2007, to wash their vehicle's undercarriage in the winter and spring to remove salt or other de-icing chemicals. It also recommends regular checks by a mechanic to make sure everything is in proper order. According to the investigation documents, for just the GMT800 platform models, NHTSA found 3,645 complaints of brake line corrosion, which included allegations of 107 crashes and 40 injuries. The issue was found to be more common in vehicles over 10 years old. GM has released a statement (embedded below) that the company "supports the consumer advisory from NHTSA urging regular maintenance and care of brake lines on older vehicles." NHTSA Closes Investigation into Brake-Line Failures NHTSA 13-15 Thursday, April 9, 2015 Agency issues safety advisory on preventing undercarriage corrosion WASHINGTON – The Department of Transportation's National Highway Traffic Safety Administration (NHTSA) today issued a Safety Advisory and consumer video encouraging owners of model year 2007 and older trucks, SUVs and passenger cars to inspect brake lines and thoroughly wash the underside of their vehicles to remove corrosive salt after the long winter in order to prevent brake-line failures that increase the risk of a crash.

2019 Chevy Silverado 1500 vs. 2019 Ram 1500 vs. 2018 Ford F-150: How they compare

The full-size pickup truck market is seriously hot right now. Both Ram and Chevrolet have introduced completely redesigned trucks, the 2019 Ram 1500 and the 2019 Chevy Silverado, and as the companies slowly roll each one out, more and more information comes to light. We've put together this comparison post to help you keep track of all the features and specifications of each of these new models, along with the updated 2018 Ford F-150. Among the stats we'll take a look at are engines, power, fuel economy, trim levels, weight and more. Weight savings Both the 2019 Ram 1500 and 2019 Chevy Silverado 1500 have gone on a diet for the new model year, similar to the one the F-150 went on in 2015. The Silverado is the weight-loss leader, having shed 450 pounds when comparing quad-cab V8 models. The Ram 1500 lost 225 pounds compared to the current truck. Both trucks achieve their weight loss in part due to the use of aluminum parts. On the Silverado, the hood, doors, and tailgate are aluminum, while on the Ram, just the hood and tailgate are aluminum on the body. Compare that to the F-150, which uses aluminum for all exterior body panels for a total weight loss of up to 732 pounds, which makes the aluminum-intensive F-150 the weight-loss leader. View 160 Photos Engines and transmissions There's only a bit of overlap in powertrains on the Ram 1500 and Chevy Silverado. Each has a V8 for the top engine. The Ram's is a 5.7-liter Hemi V8 making 395 horsepower and 410 pound-feet of torque. The Silverado will once again use a 6.2-liter V8 as its range topper with the same 420 horsepower and 460 pound-feet of torque as the current model. Both of these V8s boast some extra fuel saving technology. The Chevy's 6.2-liter (and some 5.3-liters) comes with the company's latest cylinder deactivation system that can shut off any or nearly all of the eight cylinders. The Ram's V8 boasts an optional 48-volt mild-hybrid system that, in addition to likely helping fuel economy, can provide up to 130 pound-feet of torque right off the line. With the Ram, fuel economy sees an improvement of 2 mpg in the city and combined ratings for 17 and 19 respectively. Highway fuel economy improves by 1 mpg to 23 with two-wheel drive and 22 with four-wheel drive. The Silverado's 6.2-liter V8 only improves city fuel economy by 1 mpg to 16, and actually loses 1 mpg on the highway. The new 5.3-liter engine with the fancy cylinder deactivation does see an improvement over the simpler version.

GM says its electric pickup truck is 'in development'

GM President Mark Reuss just reiterated the company's support for an electric pickup project. He also claimed that GM is going to be selling its future electric cars at "very average transaction prices" during the same conference with Wall Street analysts. Previously, Mary Barra informed the world of GM's electric pickup truck aspirations, but didn't tell us anything else. Reuss says the truck is already in development, though, according to a Wards Auto report. "We will have a complete electric lineup, including a pickup truck that's in development," Reuss said. This comment marks the second time GM has gone on the record about its intentions to bring an electric pickup to market. Additionally, Reuss said GM's third-generation global EV platform will be used to help develop the electric pickup. This platform was recently announced to underpin at least 20 new EVs from GM in the future — the platform itself is slated to be unveiled in 2021. Of course, this platform will be flexible and modular to allow various body styles to be used with it, a truck being one of those. Reuss still hasn't said what GM brand the pickup will be sold under, or what class of truck it will be. GM thinks this new platform is also going to be what helps it drive down the cost of building EVs. "We'll reach parity a lot sooner than people think," Reuss said comparing EVs to traditional gas-powered engines. "We're driving down the cost of batteries and the whole EV in general." As for electric pickups, Ford is also deep in development of its own electric F-150. However, neither of these truck projects have official timelines on them, so we can't say when they'll hit the market. For now, the cross-town rivals are both in development with their respective electric pickups. Even further across town is Rivian (in which Ford just invested half a billion dollars), a company that says its electric R1T pickup is right around the corner, with the official due date being end of 2020 for the time being.
