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 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:

Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events." View 33 Photos So we asked Sage Marie, Senior Manager of Public Relations for Honda and Acura. "If the car is stock, the warranty covers it on a track just as it does on the street. No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.
