Rain makes Kia EV6 blind-spot cameras useless? Hydrophobic coating fix

Kia EV6 blind-spot cameras can go blurry in heavy rain. A hydrophobic coating clears lenses fast and keeps them clean, works for Ioniq 5 and GV70 too.

Modern Kia models pack a suite of safety tech, blind-spot cameras included. Yet EV6 owners have run into an unexpected problem: in heavy rain the cameras go effectively blind. A video posted on the model’s forum shows the feed dropping out as droplets collect on the lenses, leaving the system useless — a surprising shortfall for a vehicle recognized as North America’s Utility Vehicle of the Year.

The remedy turns out to be simple. Applying hydrophobic products stops water from lingering on camera lenses and mirrors. Such coatings lay down an invisible film that makes droplets slide off immediately, returning a clear view even in a downpour.

It is worth applying the treatment once a week, or at least twice a month during the rainy season. That not only improves visibility, but also helps keep the camera cleaner.

The issue is not unique to the Kia EV6; related models like the Hyundai Ioniq 5 and Genesis GV70 are affected too. With no official fix from the manufacturers yet, owners are handling it themselves.

An inexpensive bottle from the parts aisle solves what Kia’s engineers seem to have left unaddressed. Sometimes the most effective upgrade is simply a touch of rain repellent.
