NHTSA opens safety investigations into Toyota, GM and Honda crossovers

The National Highway Traffic Safety Administration is evidently keeping itself very busy these days, as the federal agency has just announced it is launching or renewing investigations into Toyota, Honda and General Motors crossovers.
2006-2008 model year Toyota RAV4 crossovers are under review for allegations of rear tie-rod rust which can result in failure. NHTSA also said it is probing some 35 complaints about 2005 Honda Pilot models with inappropriate activation of the vehicles' stability control system. The alleged malfunction can cause the vehicles to slow down or stop in bad unsafe situations. At the moment, NHTSA is reviewing a petition regarding the Pilot issue, a move that will determine whether it needs to open a full-blown investigation.
In addition, Saturn Outlook and GMC Acadia three-row crossovers built in 2007-2009 are getting looked at for "loss of low beam headlamp" function. One complainant said the wiring in his Outlook overheated and melted. NHTSA says it has received 415 complaints about the problem and a GM spokesman confirmed that the automaker already started a "Customer Satisfaction Program" in December to address the issue.

GM reportedly recalling select 2014 Silverado, Sierra pickups over airbag issue

General Motors is recalling 843 2014 Chevrolet Silverado and GMC Sierra Crew Cab pickups, due to a fault with the vehicle's airbags. According to GM, the airbags may not inflate properly in the event of a crash. There haven't been any crashes or injuries associated with this recall, which is always good. Naturally, repairs will be free of charge, and GM will begin contacting affected owners soon.
GM has a lot hanging on the 2014 Chevrolet Silverado and GMC Sierra. Not only is it banking over $12,000 per vehicle on these trucks, as reported by Automotive News, but GM is counting on the Sierra and Silverado to take the fight to cross-town rivals Ford and Ram. The F-150 and Ram 1500 have been on a tear over the past few years, with fresh updates, advanced powertrains, and plenty of solid press while the GM trucks have been waiting for the 2014-model-year upgrades.
It's still entirely too early to judge the Sierra and Silverado, particularly as those 843 recalled trucks make up barely two percent of the over 40,000 units moved so far. But, as AN rightly states, these trucks are the most important vehicles to come out of GM since bankruptcy, with about 60 percent of global profits relating to pickups and SUVs. Starting an introduction of such a big product with a recall, however small, is not the preferred way to do things.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
