What do J.D. Power's quality ratings really measure?

Check these recently released J.D. Power Initial Quality Study (IQS) results. Do they raise any questions in your mind? Premium sports-car maker Porsche sits in first place for the third straight year, so are Porsches really the best-built cars in the U.S. market? Korean brands Kia and Hyundai are second and fourth, so are Korean vehicles suddenly better than their US, European, and Japanese competitors? Are workaday Chevrolets (seventh place) better than premium Buicks (11th), and Buicks better than luxury Cadillacs (21st), even though all are assembled in General Motors plants with the same processes and many shared parts? Are Japanese Acuras (26th) worse than German Volkswagens (24th)? And is "quality" really what it used to be (and what most perceive it to be), a measure of build excellence? Or has it evolved into much more a measure of likeability and ease of use? To properly analyze these widely watched results, we must first understand what IQS actually studies, and what the numerical scores really mean. First, as its name indicates, it's all about "initial" quality, measured by problems reported by new-vehicle owners in their first 90 days of ownership. If something breaks or falls off four months in, it doesn't count here. Second, the scores are problems per 100 vehicles, or PP100. So Power's 2015 IQS industry average of 112 PP100 translates to just 1.12 reported problems per vehicle. Third, no attempt is made to differentiate BIG problems from minor ones. Thus a transmission or engine failure counts the same as a squeaky glove box door, tricky phone pairing, inconsistent voice recognition, or anything else that annoys the owner. Traditionally, a high-quality vehicle is one that is well-bolted together. It doesn't leak, squeak, rattle, shed parts, show gaps between panels, or break down and leave you stranded. By this standard, there are very few poor-quality new vehicles in today's U.S. market. But what "quality" should not mean, is subjective likeability: ease of operation of the radio, climate controls, or seat adjusters, phone pairing, music downloading, sizes of touch pads on an infotainment screen, quickness of system response, or accuracy of voice-recognition. These are ergonomic "human factors" issues, not "quality" problems. Yet these kinds of pleasability issues are now dominating today's JDP "quality" ratings.

Hyundai recalls 570k Sonatas and Accents in two separate campaigns

Hyundai is announcing two recalls that cover a total of 569,500 vehicles in the US for two of the brand's models. There are no reports of accidents or injuries related to either problem, though. The larger and potentially more serious campaign covers 470,000 units of the 2011-2012 Sonata with production dates between December 11, 2009, and April 12, 2012 at Hyundai Motor Manufacturing Alabama. It's specifically for those with the 2.0- or 2.4-liter direct injected engines. During production of the crankshaft, metal debris might not have been fully removed, and those pieces could block the connecting rod oiling passages. This lack of lubrication can increase wear on the connecting rod bearings, and the issue can lead to a loud knocking noise or possibly even a failure while the car is in motion. Hyundai has a two-step process to fix the issue. First, the company will have the vehicles come in for an inspection, and if necessary will "replace the engine assembly." The company will also extend the warranty on the short block to 10 years/120,000 miles for all owners. Notifications will go out by November 2, and there will be a second letter when the parts become available. The other recall covers 99,500 examples of the 2009-2011 Hyundai Accent with manufacturing dates between March 1, 2009, and February 11, 2011. On these models, the brake light switch may begin to only work intermittently. This can lead to a variety of problems, including the brake lights not coming on, the inability to turn off the cruise control with the pedal, and the shifter not moving out of Park. The fix will be a replacement of the switch, and the campaign will begin on November 2.

In the affected vehicles, metallic debris may not have been fully removed during manufacturing of the engine crankshaft.

Hyundai twin-charged 1.8L GDCI gas engine expected to be more efficient than 2.0L diesel

Despite the growing trend of automakers offering diesel-powered or electrified powertrains, there's still a whole lot that can be done with the good-old gasoline internal combustion engine. And at Hyundai, that's exactly what's being worked on - new gasoline engine technologies that improve both performance and efficiency. During an event at the automaker's technical center in Superior Township, MI on Friday, Hyundai gave Autoblog a glimpse into the future, offering up preliminary details on its new GDCI (Gasoline Direct-Injection Compression) engine - something that will be heading to production soon.
Hyundai's main goal with this GDCI engine is to "achieve diesel levels of fuel efficiency with conventional gasoline," according to Nayan Engineer (yes, his last name is Engineer), one of Hyundai's powertrain gurus. What's more, Engineer says the GDCI engine will offer "equal to better performance than conventional gasoline engines" and will have a "lower system cost [than] diesel engines."
Hyundai expects a 1.8-liter GDCI engine to be more efficient than a comparable 2.0-liter diesel engine with similar performance.
