I have a 2020 Hyundai Elantra Limited that was purchased new in December of 2020, has 17,764 miles, and no damage. At the end of May/early June of 2026, the car gave warning messages for the following: check forward collision avoidance assist system, check lane keep assist system, and check high beam assist system. The car was inspected by the dealership, from which it was purchased, on June 29, 2026. The technician report says error codes C1604 and C1606 were found and that the car required replacement of the front camera system at the cost of $1991.49. Front camera failure negates the ability to use the advanced safety features of this car. These features are so important to alert and, more importantly, assist the driver avoid accidents and improve all motorists safety. I have read numerous complaints depicting the same problem with this front camera system. Hyundai issued TSB 20-BE-006H due to multiple problems just like the one that happened to me. I have corresponded with Hyundai about this situation and my concerns on why a car with this few miles and no damage had a failure of this magnitude. They are unwilling to assist due to the warranty expiring 6 months ago. For components this important to the safety of all drivers, I would like to see a recall established to hold Hyundai accountable for faulty components. Safety should not be limited by a warranty and last longer than 5 1/2 years. Than you for your consideration.
My car does not have forward collision warning or lane departure warning. But sometimes it will randomly pop up and the screen and cause my breaks to abruptly stop and almost crash.This has happened atleast 8 times and the car was bought brand new in 2020
