2014 Infiniti Q50's novel drive-by-wire steering system recalled

The gradual replacement of mechanical components in automobiles with electronic systems brings with it definite advantages, but also poses certain potential dangers. Just think of the inevitable problems you've encountered with the computer on which you're reading these words and you'll know what we mean. But a computer crashing isn't as problematic as your car going on the fritz when its electronic systems fail.
That's what Infiniti is being reminded of with its new drive-by-wire electronic steering system. The Japanese automaker developed and installed the Direct Adaptive Steering System in its new Q50 sedan, but a small number of those cars on the road are now being recalled due to that system.
According to the National Highway Traffic Safety Administration, on a small number of examples, the Q50's optional by-wire system may fail if the temperature in the engine compartment drops below freezing. There's a backup mechanical setup in place should the electronic system fail, but NHTSA says that the backup system may also fail to engage in time to avoid a crash.

Infiniti releases first image of premium compact Q30 Concept

Behold, the Q30 Concept. Slated for a worldwide debut in Germany next month at the Frankfurt Motor Show, this concept previews a new entry-level premium compact that Infiniti hopes will attract younger buyers to the brand, as well as give it a competitor in a burgeoning new class that's quickly filling up with options.
What will set the Q30 apart? Aside from a bold and aggressive design that picks up where the new Q50 and many concepts have left off, Infiniti says the shape combines elements from three bodystyles, all of which appeal to the sort of buyer it's hoping snare. Can you guess which three? No peeking at the press release down below. Give yourself ten arbitrary points if your answer was coupe, crossover and hatchback.
Infiniti promises a ride height that will be high enough to earn crossover credentials, and we're guessing it's got an actual hatch back there, which leaves the coupe. Where's the coupe in the Q30's design? The influence of a two-door is a little more difficult to see with the naked eye, but what the Q30 shares with some four-door coupes on the market is a roofline that peaks and begins to slope back down before the B-pillar and rear set of doors.

Infiniti Q50 steer-by-wire system took 10 years to develop [w/video]

Infiniti's Direct Adaptive Steering (DAS) is quite a novelty - the system employs no physical connection between the steering wheel and the front wheels under normal circumstances and instead relies on a computer, clutch and steering-angle actuator to guide vehicles down the road with input from the driver.
In our First Drive review of a 2014 Infiniti Q50 equipped with the system, we weren't overly impressed by the artificial feedback. But we can't help but be impressed with how long Infiniti spent on its development: a full 10 years, according to Autoline Daily in the video report below. A staggering 70 percent of the research and development time spent on DAS was devoted to getting the steering feel right, and unfortunately, our first impression suggests their results still leave something to be desired, as we found it lacked the sporty feeling a sport sedan should have.
The weight of DAS is comparable to that of a conventional steering system due to its complexity. For example, three ECUs are used in the first-generation DAS system to ensure there's never a loss of steering, but Infiniti is refining the technology and is working to simplify it to reduce weight. One day Infiniti hopes that only one ECU will be needed to control DAS. We just hope it doesn't take the Japanese automaker another ten years to get the steering feel right.
