Toyota recalls 112,500 models for steering, transmission issues

Toyota has announced a voluntary recall of a variety of vehicles built between model years 2012 and 2015. Roughly 110,000 of the 112,500 vehicles being recalled consist of the gas and hybrid variants of the 2015 Camry and Highlander, as well as the 2014 and 2015 RAV4. The problem, this time around, is down to a circuit board that may have been damaged during manufacturing of the electric power steering system. According to Toyota, the bad circuit board can lead to a loss of power steering. Owners would still have manual steering control, although they'll have a warning lamp glaring at them from the instrument cluster the entire time. As for the remaining 2,500 vehicles, they're limited to the RAV4 EV, built between 2012 and 2014. A software issue in the electric vehicle traction motor assembly could cause the EV to shift into neutral. As with the issue affecting the Camry, Highlander and gas-powered RAV4, vehicles with this problem will produce a warning lamp in the instrument cluster, as well as a "Check EV" message. Toyota will be notifying owners of the affected vehicles via snail mail, and asking them to report in for free repairs at their local dealership. Check out the whole press release on the issue, available below. TORRANCE, Calif., March 11, 2015 – Toyota Motor Sales, U.S.A., Inc., today announced it will conduct safety recalls of approximately 2,500 Model Year 2012 – 2014 RAV4 EV vehicles; and approximately 110,000 Model Year 2015 Camry, Camry Hybrid, Highlander, Highlander Hybrid, and 2014-2015 Model Year RAV4 vehicles. In the involved RAV4 EV, components in the Electric Vehicle Traction Motor Assembly, which is part of the propulsion system, may cause the vehicle to shift to "neutral" due to a software issue. This condition will also trigger a "Check EV System" warning message on the instrument panel and turn on a malfunction indicator lamp. If the vehicle shifts to "neutral", this will result in a complete loss of drive power, which can increase the risk of a crash. Owners of the involved vehicles will receive a notification by first class mail. Toyota dealers will repair the electric vehicle traction motor assembly. In the involved Camry, Camry Hybrid, Highlander, Highlander Hybrid and RAV 4 vehicles, a circuit board for the electric power steering (EPS) may have been damaged during its manufacturing process. This can result in the loss of power steering assist; an instrument panel warning lamp will also come on.

The pre-race and first in-race report from Le Mans

The 2013, 90th anniversary edition of the 24 Hours of Le Mans has begun, tragedy marking the opening laps with the death of Allan Simonsen. We're at the track now as a guest of Audi and plan to stay through the evening, and even we haven't been able to find out what caused the accident - the only video is from just after the incident, and beyond the statement from ACO there's been no more news. The Aston Martin in the LM GTE Am class and its all-Danish drivers had taken pole in its class and was one of the favorites to win.
The pre-race report will come first, and even thought we can't spoil the race because we're only five hours into it at the time of writing, we'll put all of the news at the end in case you don't even want the updates.
Or you can go straight to the high-res galleries above.

Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.
