Toyota and Lexus recalling 235,000 hybrid CUVs and sedans over separate issues

When it rains, it pours. Toyota has announced a pair of separate but voluntary North America recalls covering approximately 235,000 vehicles built between 2006 and 2011. The larger of the two recalls targets Toyota's hybridized crossovers, the Lexus RX400h and Toyota Highlander Hybrid. 133,000 units, including 2006-2010 Highlander and 2006-2008 RX crossovers are covered in the campaign. The other recall affects 102,000 IS350 sedans, IS350C convertibles and GS350 sedans built between 2006 and 2011.
With the CUVs, the faults in the parallel circuits of the transistors can cause heat damage in the inverter assembly, triggering an abundance of warning lamps and sending the vehicle into limp mode. The Lexus sedans are being recalled due to loose bolts on the variable valve timing controller. Detected by unusual underhood sounds on startup, the issue can cause the engine to stop while driving. The inverter issue is also triggering similar recalls in Japan and Europe.
At the moment, it's unclear if any of these issues have caused any crashes or injuries. Toyota says it plans to notify owners of the recall via snail mail. Additional information for owners can be found on the recall sites for Toyota and Lexus or by calling Toyota's customer service line, at 1-800-331-4331.

Toyota develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."

Lexus LF-1 Limitless luxury crossover concept is an intergalactic flagship

A dressed-up Land Cruiser it is not. As most every manufacturer making cars in 2020 will be offering crossovers in varying sizes, Lexus has unveiled its new LF-1 Limitless concept, which has been penned at Toyota's Calty Design Research in Southern California. The vehicle is billed as a "flagship crossover," meaning it slots above the RX and offers more flair than the more truck-like GX and LX models. If the design of the concept seems sharp, it's at least in part due to the design approach Lexus calls "molten katana" — with the appearance of a Japanese sword in automotive form. The spindle grille that's been the centerpiece of recent Lexus front ends is now a three-dimensional design, which appears to mimic a "Star Wars" ship's shift into hyperspace, eschewing surrounding chrome in favor of LED lighting. The concept detailing includes slightly Tesla–like door handles, which reveal a Lexus logo in the negative space, and a roof spoiler split in the middle. Door mirrors have been shaved off, with the rear view delivered into screens around the instrument cluster, where they resemble motorcycle mirrors. The feel of hyperspace continues inside, with the perforated door trim allowing lighting through like a starry sky. There are four matching, individual white leather seats under the moonroof, and there's a dedicated light show on offer at the press of the start button, depending of the function mode selected. Most analog switches have been replaced by haptic controls grouped around the driver, or fitted in the steering wheel; all powertrain controls are either in the wheel or in the steering column. By "Limitless," Lexus appears to refer to the choice of propulsion. Reading between the lines, there doesn't seem to be a set powerplant for the vehicle, as by 2025 all Lexus model lines will be electrified in some fashion, and the production version could be a fuel-cell vehicle, a PHEV, all-electric, or gasoline-powered. There's also a hands-free driver assist level Lexus calls "Chauffeur mode." In addition, there's a fourth dimension to the concept's navigation system — time. The setup reads traffic information, anticipating possible stops on the way. The idea, according to Lexus, is that the navigation system should feel like a concierge, a virtual assistant instead of just a map screen.
