1 Exterior Lighting problem

Failure Date: 07/30/2025

Both headlights bulbs needed to be replaced several times. Passenger replacement bulb 3 times. Drivers side twice. I have sent Hyundai several emails and have not heard back from them. Case # [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

No incident - high beams inop.

3 Exterior Lighting problem

Failure Date: 12/03/2024

The high beam shutter that switches from high to low is not working. The car has 68,000 and I don't think this is something that should not work at that low mileage considering it is not in use all the time. I just dont see how it stops working all of a sudden when most of the time drivers do not use their high beams everyday. I just got inspected because its required in our state and both mechanics confirmed this problem. We bought a new bulb and that is when we found out the problem.

4 Exterior Lighting problem

Failure Date: 09/02/2024

Driver side brake light went out I did have it repaired right away since I knew it was a safety hazard for anyone behind me. And sometimes I do see the same model on the road with the same issue. I don't think the running light is a safety issue but also have a problem with that going out also.

5 Exterior Lighting problem

Failure Date: 08/26/2024

It makes noise when driving a mph.

6 Exterior Lighting problem

Failure Date: 08/18/2024

The high beams failed and Hyundai will only say that my VIN isn’t part of the recall. Service campaign t5g covers the exact same symptoms that my car is experiencing. Since Hyundai refuses to acknowledge that the safety issue in this campaign affects more than what they’ve previously admitted, myself and other owners are left to repair the defect at our own expense. A google search brings up more than a few posts of owners that were also denied the recall because Hyundai says that their 2020 Elantra VIN isn’t included in the recall. This shows that Hyundai refuses to acknowledge the full scope of the vehicles that have defect. Proper headlight function is absolutely necessary. High beams not working even cause state inspections to fail. Hyundai needs to be forced to fix this major defect in a safety critical lighting system, as it is clear that they have no desire to keep the owners of their 2020 Elantras safe.

7 Exterior Lighting problem

Failure Date: 08/08/2024

A fire started in the passenger headlight assembly. The car had only been running for about 7 minutes directly prior to the fire being noticed. At the time of the fire it was parked & turned off. No injuries. It burned thru/melted part of the bumper & damaged something with the windshield washer fluid. Several people were at risk due to there being a fire! the car was parked at a gas station when the fire broke out. I don't think they have done a thorough investigation yet. It is current at Hyundai of metairie in metairie la. According to the service technician my car is not the only one they have there that had the same thing happen. No warning signs, sounds, or anything else.

12 Exterior Lighting problem

Failure Date: 12/04/2023

I got this car right at the beginning of 2020, I didn’t even know how to use my high beams until 2-3 years in. I used them all of 4-6 times and they magically stopped working. I don’t need them often so I didn’t notice right away. I’ve known for a while now but didn’t know I could submit a form like this. And no way in hell am I paying that much money for something that broke after a few uses. I’ve heard this is very common for my car make and model; I can hear the doors of the light trying to switch open but they’re stuck or something… I’m definitely not the only one having this issue….
