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.

Personal testimonies show real-world effect of plugging in with Chevy Volt

At this point, there are tens of thousands of individual stories about what it's like to live with a Chevrolet Volt. But it also remains informative to take a look at one of these in depth. For example, one Atlanta-area Volt owner says he's cut his cents-per-mile ownership costs by almost 40 percent compared to his previous car primarily because of his ability to drive almost all the time on electric power. Jeffrey Cohen told Clean Technica that he put about 14,000 miles on his Volt extended-range plug-in hybrid for the year that ended October 2013, and that more than 92 percent of those were on electrons. He estimates his "lifetime" miles per gallon rating at a whopping 384 mpg, a figure pushed upward by the fact that he installed a Level 2 charger at home while his employer added an external 110-volt charger at work. Cohen is spending 45 cents a mile for his car, compared to 73 cents in his Infiniti M35. As a result, he's spending 45 cents a mile for his car, compared to 73 cents a mile with his prior vehicle, an Infiniti M35. About two-thirds of those Volt costs are for the $349-a-month lease payments, while 15 percent is insurance, 11 percent is for the charger and seven percent for the gas and electricity that actually powers the car. Helping lower that last figure is an overnight electricity rate that's about 10 percent of Cohen's daytime rate. Chevy parent General Motors hopes such testimonies will re-trigger sales for the Volt in 2014. Last year, GM sold 23,094 Volts, down 1.6 percent from 2012. We expect our readers have similar stories they'd like to share in the Comments.

Chevy EN-V 2.0 coming to Tianjin Eco-City in China

Chevrolet is bringing its EN-V 2.0 to the Sino-Singapore Tianjin Eco-City in China to show off the "Electric Networked-Vehicle" and demonstrate sustainable urban mobility. The small, two-seat EV concept is an updated version of the original EN-V, a vision of getting around in a future world where space is at a premium and clean air is a priority. So what better place to showcase the evolved EN-V than at the Tianjin Eco-City? The Eco-City is being developed as a planned urban space with eco-consciousness built in. The joint venture between China and Singapore offers an alternative to country living and smog-filled cities. Tianjin Eco-City, slated to be completed by 2020, will be able to offer 350,000 inhabitants clean air and water, renewable energy, green transportation and living spaces and, if all goes as planned, jobs for 50 percent of the residents. Currently, only about three square kilometers of the planned 30 square kilometers have been built, with only about 6,000 permanent residents, but there's still time. The EN-V 2.0, as the "Networked" part of its name suggests, not only features mobile internet, but can communicate with other cars around it. Along with GPS and built-in sensors, this connection between vehicles allows the car to drive autonomously (at least in theory - again, there's still time). This is ideal in an urban environment where congestion can be a major issue. The EN-V 2.0 improves upon the original concept with climate control, storage space and all-weather capability, which also make life more bearable and daily commuting possible. We first saw renderings of the updated vehicle in 2012. The Chevrolet EN-V 2.0 will be used in the Eco-City's National Animation Industry Park and Eco-Business Park of the course of the two-week demonstration. Read on below for more in the press release from GM. GM to Demonstrate Chevrolet EN-V 2.0 in Tianjin Eco-City SHANGHAI – General Motors today announced that it will begin demonstrating the Chevrolet EN-V 2.0 (Electric Networked-Vehicle) in the Sino-Singapore Tianjin Eco-City this week, signaling the company's learning and progress in sustainable urban mobility. The demonstration will help GM further understand consumers' usage of low-speed transportation tools for their daily commute. During the two-week demonstration period, the EN-V 2.0s will be used in the National Animation Industry Park and Eco-Business Park inside the Sino-Singapore Tianjin Eco-City.
