NHTSA Complaint #11680050 — 2025 HYUNDAI IONIQ 5

I have had my new car only two weeks and have driven only 500 miles. Yesterday, while driving on a freeway at constant 65 mph speed, I suddenly experienced COMPLETE POWER FAILURE. I coasted across three lanes of heavy traffic and came to a stop on the shoulder. There were no warning lights on the dashboard. I turned the car off, turned it on again, and the car drove normally. I checked on my Hyundai app and it said under Vehicle Health that all systems were normal. I called the Santa Monica Hyundai service center and was advised to drive home to Santa Barbara (on the freeway) and get in touch if the problem recurred. I drove my car some 50 miles to Santa Monica to be evaluated and the service rep said that all makes of EVs have this problem, not unusual. After some hours, I spoke to the shop foreman who said he had never seen this problem, that the diagnostics had shown no problem, that there was no indication that this had indeed happened, that he could do nothing further unless there was proof that I had experienced complete power failure, and that if it happened again I should obtain proof by videoing the dashboard and my foot pressing down on the accelerator without any response. I called the Oxnard Hyundai dealer where I had purchased the car and was advised to bring my car there for a second opinion. I drove the 60 miles to their service center. I was told by the service rep that he had never heard of this problem. I was given a loaner car to drive the 40 miles home and my Ioniq 5 was kept for evaluation. I discovered on Google that sudden power failures in Ioniq 5's are a known problem by both Hyundai and the NHTSA and that there have been recalls as a result. It seems reprehensible that Hyundai representatives in two different dealerships claimed that they had never heard of this phenomenon. I was at risk of a potentially deadly accident by losing power on a freeway. I am lucky to be alive.
