There are 19 owner-reported electrical system complaints for the 2020 Hyundai Elantrain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Within a matter of a few days my car has been stopping by itself. The car was smoking and stopping in the middle of the highway, my dealership is proving me with a new engine but is trying to have me come out of pocket for an fuel injector, please help !
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.
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 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 NHTSA 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!
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.
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.
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.
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 backup camera no longer works. The screen remains blank or turns blue.
The camera keeps flickering and does not stay on.
Car is almost stalling Randomly on the highway . The rpm’s go up and car won’t speed up slows down . Stalls very randomly I am terrified to drive it , I used to have so much confidence on a newer Hyundai .
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.
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.
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.
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

My vehicle was stolen, due to known design flaws of Hyundai/Kia.
I BELIEVE SOMEONE ELSE HAS LINKED INTO MY CAR USING AN APP, AND HAS ACCESS TO OPEN IT AND ALSO TAKE CONTROL OF THE BRAKES, ETC...
