The high beam lights don’t work. Doesn’t make changes to high. Relay, bulbs and breakers appear to be ok.

I have a 2020 Hyundai Elantra Limited that was purchased new in December of 2020, has 17,764 miles, and no damage. At the end of May/early June of 2026, the car gave warning messages for the following: check forward collision avoidance assist system, check lane keep assist system, and check high beam assist system. The car was inspected by the dealership, from which it was purchased, on June 29, 2026. The technician report says error codes C1604 and C1606 were found and that the car required replacement of the front camera system at the cost of $1991.49. Front camera failure negates the ability to use the advanced safety features of this car. These features are so important to alert and, more importantly, assist the driver avoid accidents and improve all motorists safety. I have read numerous complaints depicting the same problem with this front camera system. Hyundai issued TSB 20-BE-006H due to multiple problems just like the one that happened to me. I have corresponded with Hyundai about this situation and my concerns on why a car with this few miles and no damage had a failure of this magnitude. They are unwilling to assist due to the warranty expiring 6 months ago. For components this important to the safety of all drivers, I would like to see a recall established to hold Hyundai accountable for faulty components. Safety should not be limited by a warranty and last longer than 5 1/2 years. Than you for your consideration.

Unknown and about 4 months ago my headlights stopped working one would go out I’d replace the bulb then the other goes out then a different bulb in my headlight would go out I’d replace it and it would go out again then the connectors were unresponsive then my height beams won’t engage leaving me with little to no light in order to operate my vehicle at night and oddly enough they would disengage while driving leaving me visually impaired while driving

Headlight high beam do not work after 2 years. Regular lights work but when turning on the high beam the sign comes on but the high beam does not come on

The headlights failed their soldered incorrectly. It looks like a child did it. The back camera has yet to work since shows black screen, and then the lane Assistant shuts off in the middle of the road and there’s nothing blocking it. lights went out and kept going out no matter how many times I replaced the bulb when I was on the highway. I took it into Firestone and they stated that the company fucked up the wiring system.

The manufacturer's Executive Case Management has ceased communication after verifying a total headlight failure. Despite providing evidence that the vehicle is grounded 150+ miles from home during a snowstorm, Hyundai is refusing to authorize the remedy outlined in TSB 20-BE-004H. This non-responsiveness to a verified safety hazard (Invoice #XXX) is actively endangering the driver and the public.

The headlights still cannot be used on high beam as the lights strobe when used. This was complaint was previously submitted with the same Vin#. This is dangerous for driver and others, including oncoming traffic. The local Hyundai dealer said it is would be $200+ for them to diagnostic and if they fixed it, the diagnostic fee would be credited toward the repair. How can this not be coved under a recall when it is clearly a safety issue and many mentions on line with others having the same problem? The vin.# says there are no open recalls. How can I get this covered on my car that is the same model and year as others with the same problem. I see a couple service bulletin's and would like to know if any apply. Please respond with any help or suggestions on this matter as I need help from the federal safety agency to get Hyundai to fix it. I am happy to send a video for proof. I look forward to your reply. Thank you very much!

The vehicle suffered a total, simultaneous failure of both low-beam and high-beam headlights due to a known manufacturer defect involving internal wiring and melted pigtail sockets. This matches the failure pattern described in Hyundai TSB 20-BE-004H and Service Campaign T5G (TSB 21-01-004H). ​On January 22, 2026, Robert Woodall Hyundai (Danville, VA) inspected the vehicle and confirmed on Invoice #[XXX] that "BOTH HEADLIGHTS ARE INOP". Despite this verification and the presence of technical bulletins for the ADa model line, the dealer refused the repair and refused to submit a Goodwill Authorization request as mandated on Page 2, Note 2 of the TSB. ​The Service Manager (Alan Pyles) claimed in an email that the TSB had "expired," despite the defect being active and documented in more recent campaigns. Releasing a vehicle with documented inoperative headlights creates an immediate safety risk for nighttime operation.

Vehicle has ongoing issues with headlights prior to purchasing, they claim to have repaired & satisfied recall, however, they replaced headlights with the same faulty part the replacement lights are the same, with same issues, no high beams they have a steel rod operating a plastic gear that operates a shutter to dim & operates high beam. The problem is with the heat of halogens the rod gets hot and melts the gear connection rendering the shutter inoperable so as it is , we get a year and a half out of them then they are junk. Dealer cost is 900 dollars each just for 1 light. If dealership installs 2000 dollars. The issue is, they didn't reengineer the unit! Just keep selling faulty parts! There is no way we should have to go through this every year and a half. So we're going around with no high beams ( I'm including all owners) many complaints. Foremost, it's an obvious safety concern! I've been to Bergstrom Hyundai 3 times called corporate HQ no results. In addition, the bulbs constantly burn out. I may get 4 months out of them before replacement is needed 40 dollars each suggesting a electric current surge issue idk for sure. In closing, the manufacturer must redesign the units. They should last the lifetime of the vehicle ( not the bulbs obviously). The high beam operation system. They need a push to motivate them to correct safety concern thank you!

The head lights will not go into high beam mode. When the high beams are turned on, they initiate and then flicker back and forth from on and off and will not remain on. This happens simultaneously with both lights. It appears to be a electrically issue with the high beam setting and the current not remaining constant. I have taken it to two different shops and they said it is a common with this car and to check for a recall because they have had others that had the same issued recalled. My VIN does not show a recall. This issue can also ONLY be corrected by Hyundai. The places that I have taken it to said there is a special tool they have to use to even get to this component. I noticed this starting a few months ago and still has not corrected. I have not been able to use my high beams since Aug/Sept.

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…
