Hyundai to recall 27,500 Genesis sedans over brake issue

Following an investigation launched by the National Highway Traffic Safety Administration earlier this week, Hyundai will reportedly recall 27,500 Genesis sedans due to braking problems. Roughly 40,000 Genesis sedans from the 2009 model year were originally under investigation, but this official recall affects vehicles from 2009 to 2012.
A Hyundai spokesperson told The New York Times that brake fluid may cause the brake control unit valves to corrode, which reduces braking power. Affected cars will have their brake fluid replaced, and if necessary, will have the control unit replaced, as well.
The original NHTSA investigation was launched after the government agency received 23 complaints from owners citing reduced braking power and increased pedal travel. One incident reportedly resulted in a crash, while another caused a driver to lose control of the car. NHTSA has not officially announced the recall as of this writing.

Senator calling for answers from Hyundai and Kia over MPG debacle

Hyundai and Kia have already gone public with plans to make good on the inflated fuel economy claims scandal that has rocked both companies in recent weeks. But one US senator, Jay Rockefeller (D-WV), is skeptical that the general public will see much good from the proposal, and he's looking for answers.
To recap: Hyundai/Kia have agreed to compensate owners of 900,000 affected vehicles for real versus previously claimed fuel mileage (as well as adding in a one- fifteen-percent premium), by way of pre-loaded debit cards. It has been speculated that this payout could crest $100 million by the time the Korean automakers are done writing checks.
Said Rockefeller to The Detroit News, "While I believe this is a positive step, I am concerned that many affected customers may not learn about the program or may find it burdensome to participate in the program." Rockefeller would reportedly like to see a monitoring system for the paybacks more clearly defined, with the goal being as many wronged car buyers as possible getting the recompense that they're due.

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.
