Infiniti recalls Q50 and Q70 Hybrid models

Infiniti is issuing three separate recalls for its Q50 Hybrid and Q70 Hybrid and M35 Hybrid covering roughly 13,794 vehicles in North America.
The larger campaign listed by the National Highway Traffic Safety Administration covers 5,831 examples of its 2014 Q50 Hybrid (shown above) and 2014 Q70 Hybrid in North America, with 5,412 of those in the US and its territories. According to NHTSA, "due to a software error, the electric motor may stop working while the vehicle is being driven using the electric motor only," creating a "stall-like condition." To fix the fault, the company is reprogramming the motor inverter software, and owners should be contacted in mid-November.
The second recall covers just 890 2014 Q50 Hybrid and 2014 Q70 Hybrid models in North America, with 817 of those residing in the US. It's possible that their transmission housings were damaged during manufacturing, and on affected models, the housing could have a crack that might fracture while driving. Dealers will inspect the transmission and faulty examples will be replaced.

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.

Infiniti Q70 adds long-wheelbase model, fresh looks for 2015

After all the work done for the Q50, Infiniti has finally given some attention to its flagship sedan, the Q70 (or, for those that refuse to use the brand's latest nomenclature, the M). While the refreshed sedan sports a few visual tweaks, the big bit of news is that it's the first vehicle in its segment to offer both long- and a short-wheelbase options (keep in mind, both BMW and Audi offer LWBs in China, but not in the US).
Infiniti has stretched the standard car's 114.2-inch wheelbase to 120.1 inches, lengthening the car 7.3 inches overall. Nearly the entire wheelbase increase is dedicated to rear-seat legroom, with a substantial increase of 5.6 inches overall. As for the effect the stretching had on the Q70's looks, well, we actually think it might look better with the longer wheelbase.
It's a nice change of proportions that is complemented by the fresh looks of the facelifted Q70. New head and taillights are the biggest changes, with full LEDs in the back and LED accents in front. There's certainly a bit of Q50 in the front, thanks to both the headlights and the new "double-arch" grille, complete with mesh-finish inserts. In the cabin, material quality looks to remain impressive, with Infiniti's cool silver-dust wood trim being shown off in the press images. Outside of that, interior changes are kept to a minimum.
