A total of 19,743 Hyundai Ioniq 5 and Kia EV6 electric cars are being recalled over rollaway concerns.

Separate recall notices from Hyundai and Kia both state that a "software error in the Shifter Control Unit" in affected vehicles could disengage park, allowing vehicles to roll. This could happen because of a voltage fluctuation when a vehicle is off and in park, which could interrupt the signal from the Shifter Control Unit to the parking mechanism.

The recalls encompass 10,729 Hyundai and 9,014 Kia vehicles. The Ioniq 5 and EV6 share the E-GMP platform, and there is significant component and software sharing between the two models as well. Hyundai also informed the National Highway Traffic Safety Administration (NHTSA) that the 2023 Genesis GV60 and G80 EV use the same parking mechanism, but these EVs haven't gone on sale in the United States yet.

Owners will be informed when to take their cars to dealerships to have the Shifter Control Unit software updated free of charge. Until then, owners are advised to park their vehicles on level ground whenever possible.

Even though this is a software issue, it underscores that Kia and Hyundai still can't deploy over-the-air fixes or upgrades to the propulsion or safety systems—even though the E-GMP platform is capable of it.

Tesla has, for years, has been able to address issues that would otherwise require a physical service visit by deploying a firmware fix over the air. Although sometimes Tesla does need to remedy recalls with service visits. For example, a Model 3 and Model Y recall issued last year required service centers to physically inspect brake-caliper bolts that could have been loose.

Which U.S. city is installing curbside chargers on request? Is it possible that brake dust emissions are higher for EVs? This is our look back at the Week In Reverse—right here at Green Car Reports—for the week ending May 27, 2022. This week we presented a couple of drive reviews. In a review of the 2022 Hyundai Tucson Plug-In Hybrid, we saw this model’s two-hour charging, 33 electric miles, all-wheel drive, and striking design delivering a more appealing package than the Ford Escape PHEV, although it doesn’t measure up to the extra performance and range of the Toyota...

Results from J.D. Power suggest that merely getting a ride in an EV doubles the chance of considering one.

Another U.S. factory is a possibility for VW’s Scout EV brand. DC is considering putting a premium on heavy vehicles; will it affect EVs? And getting the word out about EVs is still an issue. This and more, here at Green Car Reports Study results from J.D. Power suggest what we’ve long...

A proposal mainly aimed at heavy-duty pickups could also impact EVs, as their battery packs can add thousands of pounds.

VW might be looking away from both its dealerships and Chattanooga for a U.S. factory for its Scout EV brand, a recent report suggests.

The Lucid Air has been recalled over a wiring issue—but nothing to do with its ace propulsion pieces. We sum up why we like the EV6 just a little bit more than the Ioniq 5, but why we think an important piece of tech is missing from both. And are brake-dust emissions from EVs something to be...

The Kia side of this nearly identically equipped dynamic duo of EV cousins is tuned better—although a recent rainy-weather drive in a RWD model put heat pump tech on our wish list.

Even though EVs use the friction brakes less, some data suggests they generate more brake dust—and the EU is looking to contain that.

The fault involves a wiring harness that may not be secured properly in the affected cars—although it affects less than 1% of recalled vehicles.

Polestar invests in some very fast-charging batteries, and Stellantis partners with Samsung SDI.
