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.

GMC Hummer EV hits Neiman Marcus Christmas catalog for twice the price

This winter season, Nieman Marcus is getting into the true meaning of Christmas by offering a bunch of seriously expensive stuff in its annual holiday catalog. There's usually at least one automotive offering, and this year it's a 2022 GMC Hummer EV Edition 1 for an eye-watering $285,000. That's $172,405 more than the regular Edition 1 crab-walker, which is priced by GMC at $112,595. And what does one get for more than 2.5 times the cost of the most expensive electric Hummer? Well, hold your 1,000 horses, because this isn't just any Hummer EV Edition 1. No, it's a one-off Barrett-Jackson Hummer EV Edition 1. The interior of this Barrett-Jackson edition Hummer has been "curated" by Craig Jackson himself. And by curated, they mean it has a bunch of red trim everywhere and is garnished with a Neiman Marcus logo. Aside from that, there is nothing appreciably different about it. No performance upgrades, no special paint job. You do get an electric charging station at home, though, which might be the most useful addition to this whole enterprise. If that's not worth the price of an entire 1.5 extra Hummers to you, there's more. You get two VIP passes for the opening gala of the Barrett-Jackson auctions in exotic Scottsdale, Ariz. During the auction, you'll get access for two to Carolyn and Craig Jackson's personal skybox from where you can watch 1,500 cars trade hands. But don't get too comfy, because at some point you'll be invited on stage to receive your Hummer EV in front of a gaggle of inebriated fishing boat dealership owners. Oh, and you'll also get to bang the little auction hammer. You can pair the Hummer with other gifts in Nieman Marcus' "fantasy" catalog, like a $6.1 million dollar diamond ring. However, if you go with the $395,000 Great Gatsby-style roaring '20s party, make sure it doesn't end with the 9,000-pound Hummer Daisy Buchanan-ing any bystanders.

GM mulling off-road variants of fullsize SUVs

According to General Motors, owners "just love off-roading with [its fullsize body-on-frame sport utility vehicles]," namely the 2015 Chevrolet Tahoe and Suburban and GMC Yukon. If that's the case, it's a bit odd that sales of the previous generation of these models with the Z71 off-road package didn't sell particularly well.
Perhaps, considering this disconnect between owner's thoughts and desires with actual sales, it's not surprising that General Motors is reportedly "considering" an off-road specific model. That means the package would include styling changes and badges along with suspension modifications and larger wheels with appropriately sized fender flares.
There's no indication if the off-road model would be called Z71 or when it may potentially go on sale, assuming it ever goes on sale at all.
