Between floor mat and throttle pedal issues, Toyota has an 8.1-million-vehicle worldwide recall on its hands – but that number could be poised to grow. Reports are now in that Japan has ordered the troubled automaker to start an investigation into potential braking issues in the automaker’s top-selling Prius hybrid.

Automotive News says complaints of brake issues on the current Prius have been filed in both Japan and North America, with most complaints filed since the end of last year.

“All the complaints were nearly the same,” Toyota spokeswoman Ririko Takeuchi told Automotive News. “They are usually about driving in bumpy or icy conditions and when you push the brake, there is an unusual feel.”

We’re used to an odd sensation when a hybrid vehicle transitions from hydraulic braking to regenerative (i.e. using the electric motors to slow the vehicle) braking, but complaints registered with the U.S. National Highway Traffic & Safety Administration (NHTSA) suggest a momentary pause in braking over loose surfaces that, according to complaints filed, has led to at least one accident.

Japan’s Ministry of Transportation hasn’t commented on its directive, and NHTSA has yet to issue an investigation of its own.

Meanwhile, the NHTSA is launching an investigation into the drive-by-wire electronics of several Toyota models, in a search to determine if floor mats and sticky pedal actuation are actually the end story with regards to unintended acceleration issues.

Over the last few years, sales of pickups for personal use have dropped dramatically. It’s been a long, slow road to recovery in this country, and we still haven’t seen truck sales improve. Making things worse, guys who work in construction are among the most dedicated to buying pickups for use on the job, and there isn’t a lot of that going on right now, either.

How did truckmakers respond to this sudden, dramatic, and prolonged change in the marketplace? Instead of sticking solely with the mainstream-market formula, they’re focusing on catering to the specific needs of truck people. That helps explain the interesting grouping of vehicles for the latest Truck of the Year event. Four qualified: the Ford F-150 SVT Raptor, the Ford Transit Connect, the Ram Heavy Duty, and the Toyota Tundra 4.6-liter work truck.

First contender is the off-road race-ready Ford F-150 SVT Raptor. Instead of taking the street-biased high-performance route of the Lightning, the design team looked at the strengths of the truck platform and redefined the idea of high performance. The Raptor is ideally suited to romping over the ruts and sand of the Baja 1000 and only gets better the faster you go. And even though the extended-cab powered by a 5.4-liter V-8 is an impressive combination, we hear a crew cab and 400-plus-horsepower, 6.2-liter V-8 are coming.

Some of you may wonder why on earth there’s a little van in Truck of the Year. The Ford Transit Connect is no kid-toting minivan. This is a van built for work, with a 1600-pound payload, comparable to that of any half-ton truck on the market. This van, which has been sold in Europe for many years, has been put through truck-durability testing and is ready to take on full-size vans for a piece of that market.

For those who need to be able to tow a fifth-wheel trailer or carry 5000 pounds of equipment in the bed, the Ram Heavy Duty arrives for 2010 with a revised platform, all-new sheetmetal, redesigned interior, and several innovations. These trucks are available as 3/4- and one-ton models, plus 4500 and 5500 trucks for even more capability.

Despite the effects of the Great Recession on personal-use truck sales, there is still demand for pickups ready to do hard work. The heavy-duty truck market has gotten smaller, but the guys who buy those pickups are fiercely loyal to the segment-they need the extreme capability these hard-working haulers provide. Some may wonder why anyone would own a truck that can tow nearly 20,000 pounds, but for a lot of people in construction, those who transport vehicles or goods, and those with ranches, this is just a part of everyday life.

Within the next few months, the heavy-duty category will heat up, as all three manufacturers have all-new offerings coming. The Ram Heavy Duty is the first to market, and it’s already ahead of the game. When Ford and GM’s all-new heavy-dutys come out, both new diesel engines are going to require urea injection to meet emissions requirements that take effect January 2010. The Ram Heavy Duty’s Cummins inline-six turbodiesel, which puts out an impressive 350 horsepower and 650 pound-feet of torque, met those requirements — without urea — over a year ago.

Instead, the Ram 2500 and 3500 use a NOx adsorber with precious metals that convert the NOx into inert gases. Not only does this mean the Ram’s emissions and exhaust systems are less complex than those in the upcoming Ford Super Duty and Silverado/Sierra HD (which could improve reliability and help keep maintenance costs down), it also means that, at the dealership, the Ram will very likely have a price advantage over its competitors. And while in this size category diesel is king, there are plenty of heavy-duty truck buyers who prefer gas power. The 5.7-liter Hemi, the Ram’s base engine, has the most horsepower (383) and torque (400 pound-feet) of any V-8 in its class — and only the Ford Super Duty’s V-10 has more torque than the Hemi, but it still has less horsepower.
