Infiniti is recalling a number of 2014 Q50 sedans over a software glitch in its steer-by-wire system. According to Infiniti, 23 vehicles are affected by the recall. The recall covers Q50 sedans fitted with direct adaptive steering software that could disable the power steering software when its engine compartment reaches freezing temperatures, Nissan told the United States National Highway Traffic Safety Administration.
While a mechanical backup system that prevents steering failure kicks in via a clutch if the direct adaptive steering fails, NHTSA said the backup may not engage in time if the direct adaptive steering fails, thereby increasing the risk of a crash. Owners of the 23 Q50s have received instructions to have their cars towed to the nearest Infiniti dealership.
Q50 features an innovative steer-by-wire system that Infiniti spent ten years developing. It is the only steer-by-wire system available in a passenger car in the US. The steer-by-wire system is designed in a way that steering and the front wheels would have any actual physical connection. Instead, the Q50 employs a computer and a steering angle-actuator to direct the front wheels.
The system employs three redundant electronic control units that allow for two more backups in case the main ECU fails. Infiniti is hoping to further cut the complexity, weight, and cost of the steer-by-wire system. Mercedes-Benz also had Bosch's Sensotronic brake-by-wire system, but dropped it following a recall that affected 1.3 million vehicles.
While Infiniti sports cars have always been known for their remarkable sizes and presence, the all-new Infiniti Q50 brings another dimension of first-rate style.
Its powerful first impression is tied down by the sleek yet dynamic character line emerging from its "double arch" grille. It vivaciously flows through the bodyside like a wave and converges with the rear end, generating a highly fluid and intriguing silhouette and completely conveying the Infiniti Q50's dynamic and energetic position.
The Infiniti Q50 mirrors the direct effect of the Infiniti concepts known as the 'Infiniti Trilogy', especially Essence, while giving tribute to the quintessential design dynamics of prior Infiniti sports cars. The all-new Q50's energetic and firm appearance mixes its lower and more extensive proportions with improved interior space to striking effect inside and out.
Vintage Infiniti exterior design highlights include the "double arch" grille, dynamic arch roofline and Crescent-cut C-pillar. The front end is determinedly audacious, with a sport front fascia given on the Q50 wear models. The fresh grille's three-dimensional, textural quality is given by intricate detailing of the waved mesh pattern surface and chrome surround, while the exclusive LED headlights and marker lights' keen lines propose an almost human appearance.
The slender, powerful body sides are built to anchor the performance position with a potent, firm "bone" and arched roofline that glides to the Crescent C-pillars that are like those that first showed up on the Essence Concept.
In the rear, the side character lines flawlessly converge with the shape of the rear LED combination lights. The prominent rear double-arch trunk line finishes the robust, exceptional view from behind. Heated outside mirrors with incorporated LED turn signals are standard, while a power sliding and tilting glass sunroof is optionally available.
