65k Kia Sorento models face NHTSA probe for shattering sunroof

The National Highway Traffic Safety Administration isn't ready to give up its investigation into spontaneously shattering sunroofs in the 2011-2013 Kia Sorento yet. In fact, it has actually broadened it into a full engineering analysis affecting as many as 65,347 vehicles.
The investigation started in 2013 when NHTSA received 15 complaints about breaking sunroofs in the crossover. Since then, the regulator requested data from Kia and found that there have been 95 complaints of the roof abruptly braking. In many of those cases, the vehicle was moving at the time. People have been injured when this happens; NHTSA found 14 incidents where at least one person in the vehicle suffered from cuts or scrapes.
According to the investigation document, Kia also conducted its own internal review but couldn't find any defects. The company claims that the only way for the roof to break is for an object to strike it. Although, it does admit that the large surface of the sunroof on the Sorento could be the cause of the high frequency of damage. NHTSA's Office of Defects Investigation isn't convinced and calls it "concerning." It's pressing forward to find more details in the engineering analysis.

Hyundai, Kia to put solar panels on vehicle roofs

Hyundai Motor Group said Wednesday that future Hyundai and Kia models will be equipped with solar panels capable of generating electricity as a way to increase fuel-efficiency and range and lower CO2 emissions. Hyundai says the solar panels will feature in the rooftops or hoods of select vehicles "after 2019" and will supplement traditional internal combustion, hybrid and battery-electric vehicles. The parent group said it's developing three different types of solar roof charging systems comprised of a solar panel, controller and battery. The first generation will be a silicon solar panel system mounted to the rooftops of hybrid models and capable of charging 30 to 60 percent of the battery per day, depending on weather conditions and other factors, starting as early as 2020. The second generation involves a semi-transparent solar roof system applied to a panoramic sunroof and capable of charging an electric-vehicle battery or a battery mounted on a gasoline engine. Hyundai says the latter configuration will help it increase vehicle exports, since solar-equipped ICE vehicles will be able to adhere to regulations limiting CO2 emissions. A third-generation system is being tested right now. It will add solar production capability in the hood and roof of EVs – but the companies don't provide more detail than that at this moment. "In the future, various types of electricity-generating technologies, including the solar charging system, will be connected to vehicles," said Jeong-Gil Park, executive vice president of engineering design at Hyundai Motor Group. "This will enable them to develop from a passive device that consumes energy to a solution that actively generates energy. The paradigm of the vehicle owner will shift from that of a consumer to an energy prosumer." To date, solar vehicle charging technology has mostly been for light-duty tasks, like cooling off the interior or trickle-charging a conventional battery, such as the system offered in the previous Nissan Leaf. Systems that do more than this have typically come with a very steep pricetag for modest capabilities. Panasonic has developed a 180-watt solar roof available for the Japanese version of the Toyota Prius Prime plug-in hybrid that is capable of adding up to 3.7 miles of range per day – at an unspecified (as of this writing) but undoubtedly high cost. Elon Musk, unsurprisingly, has also discussed making a solar roof optional for the Tesla Model 3.

Here are all the EVs with 800V charging available in 2024

As technology advances, electric cars are improving their fast-charging times. That means less time spent waiting at a DC public charger when you’re out on the road. While Level 3 chargers used to provide a maximum of 150 kilowatts of power, 350-kW chargers are become more common, making for super-fast charging Â… if your car is capable of taking advantage of it. So how do automakers improve the charging speed of their EV batteries? Some are turning to higher voltage, specifically 800V charging. What's the difference between 800-volt charging and 400-volt charging? So how does 800V charging improve upon the more common 400V EVs? Put simply, the higher the voltage, the less amperage (current) it requires to charge. In other words, with more voltage, you get more wattage (power, aka charge rate) from the same amperage (current). 800V architecture is also more efficient, with less electrical resistance, so it can use thinner cables and smaller, lighter components while needing less cooling. The tradeoff is that it is more costly, and guess who that cost gets passed on to. While automakers don't break down their pricing to show how much more you're paying for that 800V system, you'll just have to evaluate any potential purchases as a whole, and make your decision based on overall pricing of the vehicle. Thankfully, the 800V EVs on sale now are generally ones we like. Now, 800V charging capability doesn't necessarily mean an EV has 800V vehicle architecture. For instance, the GMC Hummer EV and Chevy Silverado EV operate at 400V, but with their dual battery packs, can switch to 800V when charging by temporarily connecting those packs in series. Currently, there are only a handful of EVs available with 800V charging. But if you are going to find yourself taking longer trips in your EV and using DC fast chargers more often, you might want to consider choosing one with this faster charging capability. With that in mind, these are the EVs available with 800V charging, either on sale now or coming in 2024. 800-volt EVs available in 2024 Audi E-Tron GT Chevrolet Silverado EV Genesis GV60 Genesis Electrified G80 Genesis Electrified GV70 GMC Hummer EV Pickup GMC Hummer EV SUV GMC Sierra EV* Hyundai Ioniq 5 Hyundai Ioniq 6 Kia EV6 Kia EV9 Lotus Eletre* Lotus Emeya* Lucid Air Lucid Gravity* Porsche Macan Electric* Porsche Taycan Ram 1500 REV* Tesla Cybertruck *Coming later in 2024 Green Audi Chevrolet Genesis GMC Hyundai Kia Lotus Porsche Tesla Electric Lucid EV charging
