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.

GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

The future's electric — but the present is peak gasoline. Burn some rubber! Do donuts!

I vividly remember the year 1993 as a teenager looking forward to getting my driver’s license, longingly staring into Pontiac dealerships at every opportunity for a chance to see the brand-new fourth-generation Firebird and Trans Am. Back then, 275 horsepower, courtesy of GMÂ’s LT1 5.7-liter V8 engine, was breathtaking. A few years later, when Ram Air induction systems freed up enough fresh air to boost power over 300 ponies, I figured we were right back where my fatherÂ’s generation left off when the seminal muscle car era ended around the year 1974. It couldn't get any better than that. I was wrong. Horsepower continued climbing, prices remained within reach of the average new-car buyer looking for cheap performance, and a whole new level of muscular magnitude continued widening eyes of automotive enthusiasts all across the United States. It was all ushered in by cheap gasoline prices. And as much as petrolheads bemoan the coming wave of electric vehicles, perhaps instead now would be a good time for critics to sit back and enjoy the current and likely final wave of internal combustion. Today, itÂ’s easier than ever to park an overpowered rear-wheel-drive super coupe or sedan in your driveway. Your nearest Chevy dealership will happily sell you a Camaro with as much as 650 horsepower. Not enough? Take a gander at the Ford showroom and youÂ’ll find a herd of Mustangs up to 760 ponies. Or if nothing but the most powerful will do, waltz on over to the truly combustion-obsessed sales team of a Dodge dealer and relish in the glory of a 797-hp Charger or 807-hp Challenger. Want some more luxury to go with your overgrown stable of horses? Try Cadillac, where you'll find a 668-horsepower CT5-V Blackwing. You could instead choose to wrap that huffin' and chuggin' V8 in an SUV. Or go really off the rails and buy a Ram TRX or Jeep Wrangler Rubicon 392 and hit the dunes after a quick stop at the drag strip. Go pump some gas. Burn a little rubber. Do donuts! There is nothing but your pocketbook keeping you from buying the V8-powered car of your dreams. Yes, just about every major automaker in the world has halted development of future internal combustion engines in favor of gaining expertise in batteries and electric motors. No, that doesnÂ’t mean that gasoline is going extinct. There are going to be gas stations dotting American cities and highways for the rest of our lifetimes.
