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 Q30 prototype has entry-level luxury in the bag

The Infiniti Q30 Concept signaled the Japanese brand's clear intentions to join the growing global compact premium segment. Now, as evidenced by these images, we can see development of the brand's first compact hatchback is proceeding apace.
Our spies point to the similarity between this camouflaged tester and the Mercedes-Benz GLA-Class as further evidence to the cars' shared platform, although we'll admit, we don't necessarily see the similarities. The Q30's overall look, to our eyes, is like a scaled-down, lower-riding QX50, the model previously known as EX. Infiniti design elements, like its squat greenhouse, long hood and double-arch grille are all visible.
The Mercedes-Benz connection should be clearer under the hood, though, as the Q30 is expected to be powered by the same 2.0-liter, turbocharged Mercedes four-pot that's been leading the charge throughout the brand's entry-level models, namely the CLA-, GLA- and C-Class.

Infiniti Q50S getting G37's hydraulic steering for 2016

Sometimes, new technology doesn't make things better. Take the march of power steering technology as an example. Electrically assisted systems are in vogue at the moment for their ability to increase fuel efficiency, but tuning them to offer good feedback remains something of a dark art. Some automakers get it, but most don't. The previous hydraulically assisted setups just seem to be inherently more communicative when driven with enthusiasm. And it looks like Infiniti might be learning this lesson the hard way.
In talking with Keith St. Clair, the luxury brand's head of product planning, Car and Driver has learned that the Q50S is probably going to ditch its standard electrically assisted steering in favor of a hydraulic system derived from the old G37, a model soon to be renamed the Q40. The system should make the sedan more engaging behind the wheel, but it still won't help those who tick the option box for Infiniti's controversial Direct Adaptive Steering drive-by-wire system.
According to St. Clair, Infiniti's engineers have heard the complaints of critics and previous G37 owners about the Q50S model's electric steering system, and wanted to see what they could do. They didn't have to go far to figure it out - all it required was taking the steering rack off of a G37 and putting it onto the Q50S. After a little tweaking, "the car is a blast to drive," St. Clair reports. Now, the company is said to be fast-tracking the switch, and it could be ready for the 2016 model year.
