Genesis is recalling a small batch of its flagship G90 sedans for a problem you would never expect to trace back to paint. Certain cars finished in Savile Silver can unexpectedly hit the brakes when Highway Driving Assist is active, all because the aluminum content in that color can interfere with the sedan’s front corner radar sensors. In very specific situations, the system can mistake reflected radar off the bumper and paint for another vehicle edging into the lane, which then triggers unnecessary automatic braking and a whole lot of confusion for whoever is behind the wheel.

According to information filed with regulators, Genesis has recorded 11 cases of unwanted braking tied to this issue, with no crashes or injuries reported so far. The behavior appears when Highway Driving Assist is turned on at low speeds under about 12 mph, or at higher speeds when Lane Change Assist is trying to carry out a lane change after the driver taps the turn signal. In those moments, the car’s brain is watching closely for traffic in adjacent lanes, so any false echo off the Savile Silver finish can be enough to convince it that something is cutting in.

To get ahead of the problem, Genesis is recalling all 483 G90 sedans painted Savile Silver, spanning 2023 through 2026 model years that were built between April 21, 2022 and October 13, 2025. Production of that specific color has been paused until engineers finalize the fix, which is surprisingly straightforward. The solution involves sealing the front bumper beam so the radar signal does not bounce in ways the system can misread, letting the hardware see the road instead of its own reflection. Other G90 paint colors, including the matte finish, are not affected.

Owners of Savile Silver cars are being asked not to use Highway Driving Assist until their vehicle is repaired, even if the basic warranty period has already expired. Genesis will cover the remedy at no charge and plans to notify dealers and affected customers by the end of January 2026. It is an odd case where a stylish color choice and high tech driver assistance quietly collided, and it is a good reminder that as cars get more advanced, even small details like paint chemistry can have big implications for how all that tech behaves on the road.
