2021 HYUNDAI ELANTRA Complaints

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)

The contact owned a 2021 Hyundai Elantra. The contact stated that the vehicle was parked unattended. Approximately thirteen hours later, he was notified by the fire department that the vehicle had caught fire. A police report was filed. There were no reported injuries. The vehicle was parked where the fire occurred. The local dealer was contacted but the vehicle was not diagnosed or repaired. The vehicle was towed to an impound lot and later the contact's insurance provider declared the vehicle a total loss, the cause was assumed to be electrical. The manufacturer was contacted but no additional assistance was provided. The failure mileage was approximately 24,000.

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

vehicle only has 14k miles and is showing an error message for "check forward safety system" and "check smart cruise control system" after some research found this is a very common issue with multiple Elantra's where the front radar goes bad causing safety systems such as automatic braking/acceleration, and cruise control to not work. this is a big safety issue that has been reported by many drivers. the error happened going a steady 40mph with no other cars around on an open road. nothing was hit the radar just suddenly failed

While my son was driving on the highway, the smart cruise control suddenly stopped working with "Check forward safety system" and "Check smart cruise control system".

The horn is a known issue to stop working on the Hyundai Elantra. I have had my car for 10 months, and the horn does not work. This is a very big safety concern and I have been told by mechanics and other Hyundai Elantra owners this is a constant issue.

When driving at 55MPH with cruise control on, the car suddenly accelerated to 75MPH, this happened on the open road and was able to keep under control. Auto has less than 10,000 miles. I will be contacting Hyundai customer service for a case number on this incident. First indication of a problem was cruise control, auto braking failed iin June of 2023. This follows a replacement of defective front radar unit by Hyundai which was replaced at 8295 miles on July 26, 2023. This problem first occurred in late June/early July of 2023. There was no warning.

I bought my 2021 hyuandai elantra on September 7 2023 almost 2 months ago and the emergency braking system comes on pretty often while driving my vehicle on the road and freeway so the brakes will lock on me whenever the car is in drive which could cause a serious crash and probably cause damage over time to brake pads and other things this problem has occurred over 5 times within 2 months

I keep getting intermittent HEV warnings and 12-volt light. The engine then shuts down and I have no power. This has occurred several times while on the highway and this creates a safety hazard. I have been fortunate enough that this happened while I was close to the shoulder, otherwise, it could have been critical. - The failed component(s) are the 12 volt battery and engine shutdown - With the vehicle being without power while on the highway puts other drivers and myself at risk of an accident - I have taken the vehicle to two different Hyundai dealers and they have not resolved the problem - The issue was escalated to the manufacturer Hyundai Motors and they have not resolved this issue. - The 12v battery light and an HEV warning light comes on and then the engine shuts off - This issue has been happening intermittently for the past year and I first notice it on October of 2022
