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.

The contact owns a 2020 Hyundai Elantra. The contact stated that while his son was driving at an undisclosed speed, the Lane Assist safety feature failed to function as intended. The messages “Forward Collision Avoidance”, and “Lane Assist Camera Disabled” were displayed. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the Forward Collision Avoidance and Lane Assist Camera needed to be replaced. The vehicle was not repaired because the warranty was invalid. The manufacturer was made aware of the failure. The failure mileage was approximately 110,000.

Vehicle had several non-starts. I took it to the dealer a couple of times and they could not duplicate the problem. This problem continued for a couple years before I took it to an independent mechanic. Said mechanic put it on a lift and found a loose power cable barely connected to the starter. Luckily this never caused a short, spark, or fire. From my searching online it appears this is a non-infrequent issue with Hyundai's.

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.

The camera keeps flickering and does not stay on.

The warning lamp (engine light) illuminated blinking on and off. Engine code P1327 read on the diagnostic check, riding on the expressway was a little uncomfortable, engine was losing power which is unsafe at high speeds. I’ve contacted the nearest Hyundai dealer and scheduled an appointment for the car repair. I take care of the car and any repairs for maintenance and I never have any problems whatsoever until day. After doing research Hyundai had or has a recall for my vehicle with the VIN NUMBER starting with KMH, for engine replacement and I want to know if Hyundai can fix this issue.

Aug 21, 2024 Fire

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.

The contact owns a 2020 Hyundai Elantra. The contact stated that the vehicle failed to start without approximately 15-20 attempts. The vehicle had since failed to start completely. There were no warning lights illuminated. The vehicle was towed to an independent mechanic where it was diagnosed that the starter had failed causing the engine to seize. The contact was informed that the engine needed to be replaced. The vehicle was then towed to the dealer and the contact was informed that there were two open recalls on the vehicle. The vehicle received the recall repairs however, the starter was not replaced. The manufacturer was made aware of the failure and the two unrelated recalls were confirmed with the VIN. Additionally, it was also confirmed that the replacement of the engine was no longer covered under warranty. The approximate failure mileage was 87,000.

Tens of thousands of Hyundai's and Kia's are being stolen in under 2 minutes due to a design flaw Hyundai and Kia engineers failed to address. With a quick removal of steering column cover and a USB male end, thieves can steal your vehicle. This puts the public and law enforcement at risk as these thieves flee from police at high rates of speed and use these stolen Kia's and Hyundai's to commit other crimes.

I STARTED TO HEAR A GRIDDING NOISE THAT WAS PROGRESSIVELY BECOMING LOUDER WHEN TURNING LEFT OR RIGHT WHILE DRIVING, FAST OR SLOW, HIGHWAY OR STREET, DOES NOT MATTER. I TOOK THE CAR IN AND THE DEALERSHIP HAD IT FOR A WEEK WHILE REPLACING THE STEERING ASSEMBLY COLUMN (NOT 100% SURE ON EXACT NAMES OF PARTS REPLACED). I GET THE CAR BACK AND THE STEERING PROBLEMS ARE WORSE. NOW THE STEERING WHEEL IS MOVING AROUND WHILE DRIVING. THAT LEVER THAT ALLOWS YOU TO ADJUST THE STEERING WHEEL DOES NOT WORK. I CALL HYUNDAI AND AM TOLD THEY ARE BOOKED AND CAN NOT GET MY CAR IN FOR ALMOST A WEEK. IT GETS TO THE POINT THAT DRIVING IS ALMOST IMPOSSIBLE SO I DECIDE TO TAKE THE CAR IN A FEW DAYS EARLY. AS I'M DRIVING ON THE HIGHWAY GOING ABOUT 70MPH THE STEERING WHEEL DROPS AND IS FLOPPING AROUND AND ALL POWER TO THE CAR GOES OFF MAKING STEERING EVEN WORSE THAN WHAT I THOUGHT WAS THE WORST IT CAN GET. NOW THE CAR IS IN THE SHOP FOR THE SECOND TIME FOR STEERING PROBLEMS AND NOW AN ELECTRICAL PROBLEM.
