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.

2022 GMC Hummer EV could get a rival from China's Dongfeng

The popularity of GMC's Hummer EV hasn't gone unnoticed in China. State-owned carmaker Dongfeng is reportedly planning to launch an electric version of the M50 Warrior, a Hummer-like off-roader, that will inaugurate a new sub-brand dedicated to battery-powered trucks. Without citing sources, website Car News China wrote that the division will be called M, a letter that stands for something completely different if the cars that you're into come from Munich. Executives are initially planning three models called M18-1, M18-2, and M18-3, respectively. The M18-1 will reach the market first, and it's described as an electrified M50 Warrior (pictured) with seating for six. Dongfeng will build the M18-1 on a new architecture called MORV that was developed in-house. The powertrain will develop up to 1,072 horsepower, which is 72 horses more than the most powerful version of the Hummer EV, yet the zero-to-60-mph time will check in at under 5 seconds, which is roughly 2 seconds more than the GMC. It will offer around 310 miles of range thanks to a 140-kilowatt-hour battery. Another interesting point is that the M18-1 will supposedly be much lighter than the Hummer EV — it will even weigh less than the gasoline-powered M50 Warrior that it's based on. It will tip the scale at around 6,900 pounds and stretch about 205 inches long, compared to 9,046 pounds and 217 inches for the Hummer. Of course, these numbers are purely hypothetical until the truck starts rolling off the assembly line. Speaking of, production is tentatively scheduled to start in 2023 in a factory that's currently being built in China. Dongfeng expects to sell approximately 4,160 units per month, though nothing suggests that the M18-1 will venture onto the GMC Hummer EV's home turf.

Chevy Colorado configurator goes live as GM touts fuel efficiency

While the news of today is destined to be dominated by a certain plucky Japanese roadster, props to Chevrolet and GMC for announcing its own significant bit of news about their newest pickup twins, the midsize Colorado and Canyon. The two GM-owned brands announced that the twins' 3.6-liter V6 will return up to 26 miles per gallon on the freeway.
To get such efficiency from the 305-horsepower mill, you'll need to live without four-wheel drive and be okay with a max city fuel economy of 18 mpg. The combined rating for the 2WD model sits at 21 mpg. Adding four-wheel drive drops the city and combined ratings by one mpg, while the highway rating dips from 26 to 24 mpg.
As for the twins' eagerly anticipated 2.8-liter diesel engine, it's destined for model year 2016, meaning we've got a ways to go before its efficiency and output are certified.
