Electrical system going out only at night because headlights and inside lights are turning off for a few seconds only while driving at night this has happened multiple times since august and is becoming a safety concern while driving at night it's a safety concern because this has happened incoming traffic on roads and highways. The vehicle hasn't been inspected by dealership I tried calling to get an appointment but was told there is a fee and if something electrical a may have a cost per hour to inspect. No warning lights are turning on prior to headlights and inside lights going out. During the day no issues with vehicle. I've read a few online posts from other owners with same issue.

The brake lights fail with no warning. Bulb replacement used to work. Since ownership at +70,000 miles, I have had to replace one or both of the tail light sections as they melted. The lighting harness has been changed multiple times. In January 2024 Hyundai issued a warranty extension to 15years/200,000miles. There is no date on the letter. When I tried to get my car serviced there were charges for testing to ensure that this was the problem and it was difficult to find someone to service the car in a timely manner. The police continue to issue me tickets for no rear brake lights. The Dealer who finally serviced the car indicated that the Warranty was Void as the replacement parts were not Hyundai parts. Servicing the car was well after the original warranty was already over, so why would you worry about warranty claims for original parts. They claim that they cannot diagnosis the problem without original parts. Hyundai Corporate Customer Service was no help in this matter, but they did apologize for the problem. Can't drive a car without tail lights and paying 850 for the repair is one month of my disability check.

The car warning lights turn on and the car shuts down. The problem is with the Hybrid battery that is malfunctioning. This is a serious life and death problem. After the vehicle stops it goes in neutral and rolls.

Brakes failed car did not stop once thrown in park I was going into oncoming traffic and could have been seriously hurt!!! afterwards car completely died. I have been having all sorts of issues with this vehicle 2 months after purchase. I have paid for labor several times and each time I get the vehicle back the next day the vehicle is completely dead and needs to be jumped for each use. The dealership really hasn't provided a fix, currently brake fluid sign is on. This car has been towed and serviced at least 10 times. I need help

when using the turn signals, either way, the headlights cut off. sometimes they flicker back on and sometimes they stay off.

- Miami Shores, FL, USA

When I am driving with my headlights on auto, every time I use my turn signal (and sometimes spontaneously) my headlights flicker. Sometimes it-??s just for a second, but other times it has lasted more than 3 seconds which can be very dangerous while driving at night. It is also dangerous because other drivers may think I-??m flashing my brights at them when im not. During this the dash will flicker as well. This has been happening since I got the car in 2018 so it-??s not a battery issue.

Lost power to vehicle while driving on the freeway, hybrid system warning was displayed as well as several lights to include engine, brake, and skid control. Had the dealer replace the knock sensor, 3 months later the exact same thing happened, in the same way. All the same obd2 codes were pulled both times.
