ELECTRICAL SYSTEM
The Hybrid charging system fails once the vehicle is above 75 mph. After about an hour or two, the vehicle will die on the highway. This is a reoccurring issue putting our safety at risk. The dealership cannot find what the problem is. Online forums show similar issues with dealerships unable to solve the problem.

At around 93k miles my HECU unit apparently malfunctioned at the same time as the left front tire speed indicator. All of my safety features ABS, adaptive cruise control, lane departure, lane keeping etc do not work because of this.

ELECTRICAL SYSTEM
I am writing to file a formal complaint regarding a significant safety issue with my vehicle’s backup camera system. The backup camera consistently malfunctions, displaying glitchy images with distorted lines across the screen. This issue renders the camera essentially unusable, as it fails to provide a clear view of the area behind the vehicle, posing a serious safety hazard. This malfunction directly impacts my ability to safely reverse, especially in crowded areas where visibility is crucial. The camera’s unreliability puts pedestrians and other drivers at risk, as I am unable to fully ensure that my path is clear when reversing. I strongly believe this defect poses a significant safety concern that needs to be addressed by the manufacturer. I request that the NHTSA investigate this issue and take appropriate action to ensure that this problem is resolved for myself and the many other affected vehicle owners. Thank you for your attention to this matter.

FORWARD COLLISION AVOIDANCE: WARNINGS
Several times, including yesterday, my forward collision avoidance engaged by braking suddenly and strongly and INAPPROPRIATELY, almost causing me to be rear-ended. I was nowhere near the car in front of me, and fortunately due to traffic was traveling below the speed limit. This seems to happen whenever there is an overpass above the road. I have reported this to Hyundai, and they don't seem very concerned. Very dangerous. I would think there could be a software or sensor update that can correct this situation.

VISIBILITY/WIPER
The windshield is damaged very easily when a small rock hits it on the road. It's been hit before the recall and the new windshield is damaged. It's a hazard especially if it can be easily cracked. I've had other vehicles that can handle small rocks on road ways. These are damages from tiny rocks. This windshield is very weak, the Crack continues to spread all over day to day.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
One day I was on the highway driving and the front collusion safety warning appeared. I thought the warning went off because the sensor was dirty due to dead bugs. However, I pulled over and the sensor did not appear dirty. After awhile the sensor went off on its own. Then a few weeks late the front collusion safety warning appeared again while I was driving on the highway. The warning has not fixed itself. I cannot use my cruise control. I took it to the Hyundai dealership and they told the me senor is off alignment and it will cost $500 to repair because they have to remove the entire bumper. I have seen on Hyundai forums this is a common problem.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Over the past 4 months, this car's safety sensors have randomly activated on 4 different occasions. The car will suddenly brake when this occurs, which puts me and the other drivers around me at risk of crashing. Each time, I've taken it to a Hyundai dealership for repairs. They always claim they can't recreate the issue and don't fix anything. I've provided the dealer with pictures and videos of the warning lights on my dashboard. It doesn't seem to help them diagnose the problem.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
My car has two warning lights on my dashboard. First one is Check Foward Safety system. Second one is Check Smart Cruise Control System. Both of them turned on when I was driving in the middle of a highway. These warning lights activated out of the blue, without any unusual circumstances.I cannot use my smart cruise control system and the car is not able to alert me about forward collision. This issue has already been addressed through a recall for my vehicle's model and year in Korea. My vehicle was produced in Korea and was imported to the United States; however, Hyundai has not issued a recall regarding the same problem in the United States. This is a safety concern, and Hyundai should repair it free of charge, and the company should compensate customers who have already undergone repairs for the repair costs.

ELECTRICAL SYSTEM
Since last year around 55k miles, my backup camera has stoped working. The first incident happened as I was about to back out of my garage. I opened the garage door and put my car into reverse. As I looked down at the screen and began to back up, I realized the screen showed me an image of a closed garage door ever though the door was open. Almost as if it had taken a screenshot or froze. The second occurrence was similar except it was when I was parking in a job site parking lot. When I put my car in reverse to park, what came on my screen was the image of the highway about 15 minutes prior. I’ve had several experiences like this where the backup camera freezes, has static-like lines all over the screen, discoloration, or delayed effects. This is dangerous because if someone is looking down at the screen and doesn’t realize the backup camera is giving an incorrect output, this can result in an accident (whether it be a single car or multiple car accident). This is because you can end up hitting something/someone if you get delayed feedback on the camera and don’t realize.

STRUCTURE:BODY, UNKNOWN OR OTHER
Significant water leak which I believe is due to a failure in the door seals. My personal safety is at risk due to a mold issue. The problem has been reproduced and confirmed by the Hyundai dealership’s service department (multiple visits). This problem is well documented by many individuals in the Hyundai Forums site. The results were the dealership pushes the vehicle back at the consumer without it being corrected. Problem has been occurring since purchased. I recognized the issue in early 2023

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Forward collision sensor suddenly failed to function properly. This issue was NOT caused by any damage or a collision; it happened while driving on the highway. Hyundai does not fix this under any warranty, even though the issue was not caused by damage. It appears to be a bad quality/faulty sensor.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I was driving on the Highway at the posted speed limit when the warning "Check Forward Safety System" came up and remained on my dashboard. The cruise control stopped working also. The light remained on even after stopping and starting the car and has remained on ever since. I have never been in an accident nor has my computer system reported any collision. My Hyundai Blue Link app gives me the following DTC: C162078. It started on [XXX]. My collision detection system does not appear to be working at all and my cruise control no longer works. I'm very concerned about it malfunctioning based on other entries on the nhtsa.gov website. I took the car to Hyundai Service Center and they are trying to convince me this is due to a collision and warranty will not be covering it. They tried to charge me for diagnostic even though I already had the error code on the Hyundai BlueLink App. They confirmed that my computer has zero reports of any collisions. The service tech said, and I'm quoting, "The system is very sensitive and a swift kick could cause it to malfunction." That sounds like a manufacturing defect to me. I have never been in an accident with this car, there is zero visible damage to the front bumper, and my computer has no report of an accident. The dealership urged me to contact insurance. My Major Insurance Company told me this was absurd, would never be approved, and is clearly mechanical. They also mentioned anecdotally that this problem has been coming up a lot for them with modern Hyundai models. Then I called Hyundai Corporate and they have escalated the issue, agree it sounds mechanical, and will be contacting me in 3-5 business days. They apologized profusely so I am still holding out hope for warranty coverage. I believe the dealership is trying to blame me for this mechanical failure to avoid expense on their end. I have had many software-related issues with this car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have had to get the horn replaced on my ELANTRA six times the horn goes out and this can be a very big safety hazard as it has caused people to almost hit me because they didn’t see me and my horn wasn’t working to alert them this needs to be addressed as soon as possible as this could cause someone to lose their life in the wrong instance
