NHTSA probing 400,000 Infiniti, Honda vehicles over steering faults

As many as 391,000 vehicles from Infiniti and Honda may eventually need to be recalled as a result of two, separately announced Preliminary Evaluations from the National Highway Traffic Safety Administration to ascertain the scope of the potential safety hazards.
The larger investigation has NHTSA looking into the 2013 Honda Accord because of 24 reports from drivers alleging total loss of power steering or a sudden increase in necessary effort to turn the vehicle. In four cases, the problem is reportedly linked to crashes, with all of them occurring at less than 30 miles per hour. According to the claims, 13 people also reported seeing a warning message during the failure. Turning off the car and restarting it would fix the issue in some cases. If a recall is necessary, it could affect an estimated 374,000 Accords.
The second investigation is much smaller in scope. The safety agency is investigating the 2008 Infiniti EX35 after two complaints of the steering wheel shaft separating, and the vehicle losing the ability to steer. Both reports allege that the steering became loose when driving and then completely failed once the vehicle was stopped. A recall for the problem would affect an estimated 17,000 vehicles. Scroll down to read NHTSA's reports on both Preliminary Evaluations.

2021 Infiniti QX55 will get the company in the crossover 'coupe' game

Seeing how German automakers are printing money with less-practical but arguably more stylish crossover "coupes," Japanese luxury brand is getting in on the action, too. The company announced it will introduce a fastback crossover named QX55. And while the company hasn't revealed the actual vehicle yet, it did release the above conceptual sketch. As you can see, it doesn't reveal much except that the QX55 will have a low, curvy shape. It will probably have four doors like its competitors. Infiniti says the roofline is meant to evoke the company's first crossover, the FX. We disagree on that detail, because while the FX did have a stylish, low-slung roof compared with its contemporaries, it still had a fairly conventional and upright hatch (see below). Judging by the name, the QX55 will probably be based on the platform and powertrain of the QX50. That means it should have a version of that crossover's variable-compression ratio turbocharged four-cylinder, along with front-wheel drive or all-wheel drive. Infiniti says the QX55 will go on sale in the summer of 2020, so expect a full reveal during the coming auto show season.

The yin and yang of the 2017 Infiniti Q50 Red Sport 400

When we first drove the Q50 Red Sport 400, Infiniti had the car out at a prepared slalom-and-cone course in a large, open parking lot. The car was stacked up against another Q50 without the Direct Adaptive Steer steer-by-wire system, and the course was designed to show that the DAS-equipped Red Sport 400 (it's a $1,000 option) required less steering input to master the same course. With all due respect to Infiniti, which is invested in this unfortunate system and has been working hard to revise it, the comparison doesn't make a lot of sense. The non-DAS Red Sport 400 has a steering ratio of 15:1 in RWD and 16.7:1 in AWD forms. The DAS system can vary between 12:1 and 32.9:1 in RWD and 11.8:1 to 32.3:1 in AWD flavors. At its extremes, the DAS system's ratio is vastly different than the fixed-ratio cars. So sure, with a super-quick steering ratio available, the DAS driver's going to do less work. It's all in the gearing. Does this mean it's better, that the steering feel is more natural, that it's easier to hustle quickly? The amount the driver saws at the wheel isn't an indication of that, necessarily. After a few days in a rear-drive Red Sport 400, I'm saying that the spooky disconnection between the driver and the front wheels would be a severe deficit to a driver on a real autocross course. It's not like the DAS system is choosing bad ratios within its range, it's just not supplying the feedback to make it enjoyable. Knowing what your front tires are up to is critical. I can hear you saying right now, "But what Q50 Red Sport 400 owners are going to autocross their cars?" Sure, but it was just a means to an end: showing off the DAS in a good light. And in that case, it probably did. The thing is, in isolation, not back-to-back with a non-DAS car with a slow steering ratio, the DAS system has the same issues it's always had: It simply doesn't feel natural. It doesn't feel intuitive. There doesn't seem to be any real advantage over a slightly quicker rack. I don't hear about people making buying decisions based on how much work they have to do sawing at the wheel, do you? So, that's one side of the Q50 coin – one that's hard to ignore if you're an enthusiast and steering feel is an important connection between you and the vehicle you just dropped a large hunk of change on, and will be spending a lot of your time in. The other is that there's a really compelling reason to drive a Red Sport 400: The 3.0-liter, twin-turbocharged V6 is a monster.
