2021 HYUNDAI ELANTRA Complaints

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.

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.

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.

Back up camera doesn’t work. When put in reverse the screen is static and when you press the back up camera button it won’t turn on

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.

The contact owns a 2021 Hyundai Elantra HEV. The contact stated while driving 65 MPH, the vehicle started to lose motive power with a battery warning light illuminated. The contact stated that on several occasions, the vehicle had to be turned off and restarted for the vehicle to recharge and restart. The vehicle was taken to the dealer, but the vehicle was not diagnosed or repaired. The contact informed the dealer that the failure was intermittent and within an hour the dealer stated had replicated the failure. The manufacturer was notified of the failure. The failure mileage was approximately 52,000.

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

When gas is pressed (even to floor) in drive, vehicle stalls, does not accelerate. Then vehicle jerks into propulsion after revving. Other instances, at deceleration the car will jerk and shake to a stop. I have mentioned the problem at every scheduled maintenance

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.

Pop up display "Check Forward Safety System and Check Smart Cruise Control System" during driving on the free way with no reason. 3 month ago same thing happened. fixed that problem with re-calibration to the front sensor. But. same problem happen today. This problem is recalled in south korea on last year.
