NHTSA Complaint #11706248 — 2023 HYUNDAI IONIQ 5

Due to a heavy brake application a water bottle in the back seat spilled and the water traveled under the drivers seat. This resulted in multiple car systems going offline, vehicle reporting LKAS error and inability to turn the car off. This essentially bricked the vehicle. Repair in order to correct the shorts and corrosion from the water both the drivers seat and main floor wiring harnesses require replacement cost estimate approximately $12,000. These key electrical connections under drivers seat are not adequately protected from simple water damage. This in my opinion makes the vehicle unfit for use as a family EV SUV as a simple water bottle still should not be able to brick a car. I consider this a design defect and the manufacturer is not covering this under warranty.
