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.

2017 GMC Model Year Preview and Updates

GM's 'professional grade' truck and SUV specialist continues to deliver its utility-with-luxury vibe, optimized in the all-new Acadia, relatively new Canyon and continual updates to its Sierra pickups and Yukon SUVs. GMC ACADIA: An all-new Acadia - pictured above - is aimed at the heart of the midsize segment. In an unusual step, the GMC product team downsized the Acadia, dropping 700 pounds from the earlier platform in the process. The new crossover is available in four trims – SL, SLE, SLT and Denali – and an offroad-oriented All Terrain package is available on both SLE and SLT when equipped with all-wheel drive. For young families, GMC introduces the industry-first Rear Seat Reminder, a prompt which will remind the driver to check the rear seat area before leaving and locking the vehicle. CANYON: The midsize pickup introduces two new variants for 2017. The upmarket Denali adds swag – unique chrome grille, 20-inch aluminum wheels and various interior upgrades – to its swagger, while the All Terrain X provides the adventure traveler with all-terrain tires, off-road suspension, Hill Descent Control and all-weather floor liners. SIERRA: The Sierra's maximum trailer tow rating of 12,500 pounds is the best in the full-size, crew cab segment. New features include Teen Driver, active aero shutters on all models and available tri-mode power steps. Also, GMC adds two new colors to the palette: Dark Slate Metallic and Pepperdust Metallic. SIERRA HD: The big news is the addition of the All Terrain X to GMC's heavy duty lineup. With an offroad-specific footprint provided by its 18-inch aluminum wheels and Goodyear Duratrac tires, ground clearance is enhanced by the Z71 off-road suspension, and an Eaton automatic locking differential keeps you rolling. TERRAIN: While the 2018 Terrain awaits its showroom debut, the 2017 Terrain's new Nightfall edition darkens the Terrain vibe. The one new color for 2017 fails to hit a brighter note; it's Graphite Gray Metallic. YUKON/YUKON XL: Perhaps the ultimate Uber capsule, the big/bigger SUV enters 2017 with a host of refinements, including GM's Teen Driver feature, upgrades to rear seat entertainment, available low speed forward automatic braking, active aero shutters for improved efficiency and one new color: Dark Sapphire Blue Metallic. If you're looking to maximize your visual presence, consider the SLT Premium Edition, which ups the chrome content well beyond the commercial minimums.

GM recalling 22K Silverado and Sierra trucks for seat issue

General Motors will recall 21,721 of its new 2014 Chevrolet Silverado and GMC Sierra pickups over front seats that could move if the vehicle is hit from behind. Affected vehicles all feature manual adjustments for the two front seats, according to a report from Automotive News.
Of the nearly 22,000 vehicles covered under the action, the overwhelming majority - 18,972 -- were sold in the United States. A further 2,575 were sold in Canada, while 103 were shipped south of the border to Mexico. Finally, another 71 were sold outside North America altogether. As of right now, there are no reports of injuries due to the defect.
Naturally, Chevy and GMC dealers will make the repairs free of charge, although it's not clear as of this writing if GM will be notifying owners or just addressing the issue at the truck's first service.
