2009 Hyundai Genesis under investigation for brake problems

According to The Detroit News, the National Highway Traffic Safety Administration has launched an investigation into 40,000 Hyundai Genesis sedans due to reports of brake problems. All of the vehicles in this probe are from the 2009 model year.
NHTSA has reportedly received 23 complaints from owners citing increased brake pedal travel and reduced braking power, with one of the incidents resulting in a crash. The Detroit News reports that, in another incident, the Genesis driver responded to the lack of brake effectiveness by applying the parking brake, which caused the vehicle to lose control and go into a spin. Many of the complaints indicate that this problem was simply diagnosed as a faulty ABS module.
In a statement to The News, Hyundai said it is fully cooperating with NHTSA on this investigation. An official recall may occur, depending on the results of the government agency's findings.

Hyundai CVVD engine brings another dimension to valve timing

A new technology from Hyundai Motor Group places another marker on the march to more efficient internal combustion engines. Called Continuously Variable Valve Duration, the innovation permits two options for how long the intake valves remain open during the combustion cycle. The feature adds a third take on valve chicanery, atop variable valve timing that changes when valves open, and variable valve lift that changes how far valves open. Hyundai says the feature returns a 4% improvement in performance, a 5% increase in fuel economy, and lowers emissions by 12%. Hyundai applied for two patents on the valvetrain process in South Korea in 2011 and again in 2015. The altered valve duration in this latest iteration is made possible by two movable arms inside the camshaft. Each arm is anchored at its base to a pin at the center of the camshaft, while the end of each arm extends toward the edge of the camshaft. Changing the position of the pin in the center of the camshaft changes the angle of the arms relative to one another, which moves the camshaft along its mounting rod. Voila, a new intake cam profile that either lengthens or shortens valve overlap.   During low-speed spells at low load, CVVD opens the intake valve from the middle to the end of compression stroke. The weaker detonation isn't a factor at low load, and the reduced friction during compression improves fuel economy. During heavy engine loads, the intake valve closes at the beginning of the compression stroke to maximize the amount of air mixed for detonation, boosting torque. Four additional features enhance the benefits of CVVD. A more powerful direct injection system increases fuel spray pressure from 250 bar to 350 bar. Hyundai doesn't go into details on its Integrated Thermal Management System, but says the ITMS "quickly heats or cools the engine to the optimal temperature." Low-friction components lower overall engine friction by 34 percent. And a low-pressure exhaust gas recirculation layout diverts low-pressure exhaust gas from the traditional EGR route to the turbocharger compressor under high load for better fuel efficiency.   The first engine to boast the new tech is the Smartstream G1.6 T-GDi four-cylinder, which produces 180 horsepower and 195 pound-feet of torque. It will appear in the 2020 Hyundai Sonata Turbo going on sale in South Korea later this year.

2021 Ford Bronco is here, and a Stellantis is born | Autoblog Podcast #636

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by West Coast Editor James Riswick and Road Test Editor Zac Palmer. They kick things off by diving headfirst into the Ford Bronco and Bronco Sport before moving to what they've been driving: 2020 BMW X3 xDrive 30e, 2020 Hyundai Ioniq Hybrid and a 2020 Ford Expedition. Then, the three tackle Stellantis, Chrysler's new corporate name. Finally, James and Zac reminisce and discuss their time in a couple classic Honda coupes.
