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.

Infiniti will reinvent its models, tech and design language as part of reboot

Infiniti raised more than a few eyebrows when it announced plans to follow a strategy it described as Nissan-Plus. Although this term suggests the brand's image will be dangerously watered down, its chief executive stressed its flag will remain firmly planted in the luxury car segment as he outlined what to expect in the coming years. The executive team led by Infiniti boss Peyman Kargar will reboot the company with a focus on profitability. "Premium brands should bring more money to the company, so that's the objective. We are not at the level we want to be," he told Automotive News. Several new products are on their way, including a crossover with a fastback-like roofline named QX55, and Kargar clarified many future models will ride on an architecture shared with parent company Nissan. It will be compatible with gasoline-powered, hybrid and electric drivetrains. He explained sharing platforms and components is necessary to save money because the company, like its peers and rivals, is spending a small fortune on developing electrified, autonomous, and connected technology. The shift will likely spell the end of the driver-friendly rear-wheel drive platform found under the Q50 and the Q60, but don't expect Infiniti to put its emblem on, say, a Sentra, and call it a day. It will remain a luxury brand. "The objective is to use these assets of the company, and then to reinject the money we are saving into the luxury experience and ingredients of Infiniti. We will put more money into Infiniti's future, but this money will come from the savings in globalized platforms," Kargar explained. The strategy he's outlining is one many of the firm's competitors have already adopted. Lexus, Acura, and Audi all build cars using parts sourced from their respective parent company. Lamborghini's Urus is related to the Volkswagen Touareg under the sheetmetal. Kargar noted every upcoming new model will be defined by an overhauled design language. We don't know if recent concept cars (like the QX Inspiration introduced in Detroit in 2019; pictured) will influence its upcoming vehicles. However, its future cars will offer nicer interiors, more user-friendly infotainment systems, and they'll receive tech features before Nissan's variants get them, which, oddly, hasn't always been the case in recent years. Infiniti's turn-around will start in 2020, when the aforementioned QX55 makes its debut after a brief delay.
