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.

2019 Infiniti QX50 First Drive Review | A high-tech engine flies under the radar

Update: An Infiniti representative reached out after this review was published and noted that the "Park with Easy Steering" function of the Direct Adaptive Steering system was erroneously left engaged. Infiniti says this feature "reduces feel considerably at low speeds to aid in parking", and that the Easy Steering function will be disabled by default in customer cars unless the customer chooses to engage it. This seems to explain the issues our reviewer had with low-speed steering feel, although we've had other problematic experiences with Direct Adaptive Steering in a broader sense – not to mention the fact that the drive-by-wire system has been recalled several times to fix various issues, and also recalibrated in response to criticism. We hope to get another QX50 soon, and if so we'll compare the low-speed steering response with Easy Steering on and off. Even as manufacturers rush headlong into electrification and autonomous driving, revolutionary internal-combustion engine technologies are still being developed. Consider the Mazda Skyactiv-X Spark Controlled Combustion Ignition process, for example. But Infiniti's VC-Turbo four-cylinder engine, which makes its debut in the 2019 QX50, is truly a work of engineering fortitude. The engine realizes the long-held ambition among engine manufacturers to create a way to alter the compression ratio on the fly, a boon to both power and fuel efficiency. It's a brilliant bit of science that's, unfortunately, still in search of the right car. Don't get us wrong, the QX50 is perfectly competent — it's an exceedingly quiet and comfortable cruiser. However, it's no longer the driver-pleasing machine its predecessor was. That car, originally known as the EX35, was built atop Nissan's sporty FM platform, a front-midship, rear-wheel-drive layout putting the engine aft of the front axle line and giving the vehicle the athletic driving dynamics of a sport sedan. In fact, it was basically a G37 hatchback, and it was sold as the Skyline Crossover in Japan. A shortened FM chassis underpinned the 370Z, to put a finer point on it. For those more concerned with comfort than corners, the 2019 QX50 might actually be a more useful. It rides atop an all-new front-wheel-drive chassis, which means it's able to add more space for both passengers and cargo. It trades a heap of the old QX50's sportiness for comfort and packaging efficiency. If that sounds good to you, perhaps the new QX50 is the right crossover.

Nissan sets 2017 sales record with help from Rogue, Titan, and Armada

Nissan Group said its U.S. sales climbed 1.9 percent in 2017 to an all-time record of more than 1.59 million vehicles sold. Free pizza in the conference rooms in Nashville, right? But a closer look shows the company mirroring overall industry trends, with plenty of declining-popularity cars but also a few aging trucks and SUVs. Taken together, Nissan's trucks, SUVs and crossovers saved the day, selling an all-time high of 765,624 total units, up 15 percent from 2016. That offset a 10.9-percent drop in sales of Nissan's cars, as volume sellers like the Altima and Versa posted steep drops. Also buoying overall results was the Infiniti division, which gained 10 percent from the previous year on the strength of models like the Q60 and QX30. Nissan's record year owes a lot to the Rogue, its compact crossover, which set an annual sales record with 403,465 vehicles, an increase of 22.3 percent. Sales of the Titan, Nissan's full-size pickup, grew an impressive 141.9 percent to 52,924 units, while the Armada, a full-size three-row SUV that was all-new for 2017, also saw a huge jump in sales (154.1 percent) to 35,667. Infiniti, meanwhile, saw overall sales climb 10.9 percent on the strength of huge gains by the Q60 Coupe, which rose 170.8 percent, and the QX30 crossover, which grew almost 524 percent. That being said, Infiniti volume is relatively low. The Q60 Coupe sold a total of 40,444 units and the QX30 14,093 for 2017, while Nissan shifted 40,172 Rogues in December alone. On the car side, the Maxima did well, gaining 7.9 percent to finish at 67,627. Volume-wise, the Sentra dominated, nudging up 1.7 percent to 218,451. But the rest of the lineup mirrored industry trends for the car segment, with steep drops for the Altima (down 17 percent), battery-electric Leaf (-19.8 percent), Versa (-19.2 percent) and Juke (-48.1 percent). Several truck, crossover and SUV models are also not faring so well. The aging Frontier pickup, last updated in 2005, fell 14.5 percent, the Pathfinder slipped by 0.8 percent, the Quest minivan plummeted 55.5 percent and the upscale Murano crossover fell by 11.8 percent. A Nissan spokesman says the Quest is no longer being built for the U.S. market starting with the 2018 model year. Meanwhile, reinforcements are coming. Nissan has said it's planning a new generation of the Frontier, its entry-level pickup, but hasn't clarified when.
