NHTSA investigating 561k Toyota Prius hybrids for possible steering shaft defect

The Detroit News is reporting that the National Highway Traffic Safety Administration will investigate some 561,000 Toyota Prius models for potentially defective steering shafts. The affected hybrid models are from the 2004-2009 model years. The story indicates that NHTSA is weighing whether or not to grant a defect petition, which claims that Toyota incorrectly assembled the hatchback's steering linkage.
As of this writing, there is no recall. However, a recall based on the Prius steering shaft would be the third related to steering issues for the model since 2006. Seven years ago, Toyota recalled 170K Prius models for potential cracking of the intermediate shafts, and in November of 2012, the automaker recalled 670K units to replace the steering shaft extension assembly.
We'll be monitoring NHTSA's signals to see if this investigation turns into a full-fledged recall. For now, stay tuned.

Weekly Recap: Racing legend Jim Hall explains Chevy's futuristic Chaparral concept

"I said our cars are built to be winners." – Jim Hall Racing legend Jim Hall never thought he'd be a video game consultant, but when Chevrolet asked for his advice to create a futuristic Chaparral for the Vision Gran Turismo series, he was eager to help. He reviewed early sketches and suggested some changes that made it onto the concept, including the addition of a camera that's mounted onto a mast over the cabin to aid the driver. The Chevy Chaparral 2X Vision Gran Turismo concept was revealed this week at the Los Angeles Auto Show and will be part of a downloadable update for PlayStation 3's Gran Turismo 6 in December. Theoretically, at least, it uses a laser-beam propulsion system and an air-powered generator to produce 900 horsepower in the video game. It's capable of sprinting to 60 miles per hour in 1.5 seconds en route to a top speed of 240 mph. Those gaudy performance specs – even in the virtual world – came at Hall's urging. "I said our cars are built to be winners," Hall told Autoblog on the floor of the Los Angeles show. The 79-year-old drove Lotus racecars in Formula One before launching the successful Chaparral Cars in the 1960s. Like his innovative Can-Am racers, the Vision Gran Turismo project has an eye toward the future. It also introduces the iconic Chaparral name to a new generation of fans, and hopefully, Hall says, gets them excited about engineering and design. "It emulates what we did in the '60s," he said. And what they did back then still resonates. Chaparral Racing and Chevy partnered more than 45 years ago for development work on the composite monocoque chassis, lightweight alloy powertrains, automatic gearboxes and active aerodynamics. "He [Hall] walked right back into this and was able to apply thinkings and learnings," said Clay Dean, General Motors executive director of advanced design. The Chevy Chaparral 2X Vision Gran Turismo concept was created at GM's North Hollywood advanced design studio, and it will be on display at the show through November.

Next-gen Toyota Tacoma to debut at Detroit Auto Show

Toyota's confirmation comes on the heels of General Motors' successful launch of its own midsize pickups. The next generation of the Toyota Tacoma pickup truck will be revealed in January at the Detroit Auto Show, a top executive confirmed Thursday. Bob Carter, senior vice president of automotive operations for Toyota, offered no other details, but the new version of the pickup is expected to have significant upgrades compared with the aging model on sale now. Our spy shooters caught a prototype testing this summer, and rumors of the new generation have been swirling for months. We've also previously reported that Toyota is planning to ramp up production next April at a factory in Mexico that builds the Tacoma. Toyota's confirmation comes on the heels of General Motors' successful launch of its own midsize pickups, the Chevrolet Colorado and GMC Canyon, which have garnered awards, positive reviews and solid sales since they arrived in showrooms this fall. It's unclear how large the new Tacoma will be, especially considering that the Canyon and Colorado flirt with fullsize territory. The Tacoma was last updated in 2012, and the segment has changed dramatically since then with the addition of the GM trucks. Another Tacoma competitor, Honda's aging Ridgeline, is also expected to re-launch in 2015, which would leave the Nissan Frontier as the oldest truck in the field. Tacoma sales have slipped 4.1 percent to 140,757 units this year, though they posted a 3.3-percent gain in November. Meanwhile, Carter also said Lexus will reveal two performance vehicles, though he didn't elaborate. "I'll leave it at that, but I promise you'll enjoy it," he said coyly. Lexus just showed the LF-C2 convertible concept at the Los Angeles Auto Show.
