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.

I no longer have this vehicle, as I traded it in once I was able to lower some of my negative equity. During owning the 2020 Hyundai Elantra, a deer it the side of my vehicle and knocked me into the center of the road while I was driving. No airbags had come out, nor was any sensor activated. About 6-8 months later, I was driving down the same road and a deer had run across the road. The forward collision sensor did not alert me (I was paying attention to the road, but would have absolutely heard it), and my airbags did not deploy. My car suffered over $9,000 in damage and I had a concussion.

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.

Cruise control on 55mph, car has slowed down going straight no uphill or downhill and accelerator did not work nothing blocking the accelerator. Had to pull over to a shoulder to shut engine off and on to drive. Tapping cruise control up to speed up in regulated area such as from 55 to a 65mph zone.. cruise control speed lowered. Attempting to speed up with accelerator still only slowing down. 3 times this year I had to change spark plugs within a 6 month period Error code p0302. Replaced battery alongside. Continues p0302 code. Replaced all coils and spark plugs still p0302. Climbing uphill vehicle sometimes looses power that happened twice in 2025 and twice in 2022. 3 times in 2024. That i must turn on hazards and floor the accelerator to gain speed on up hills in neighborhoods going 25 mph. I have dropped to 10 mph. I get oil change regularly. Always when due. Every few months I make sure to get a full car inspection to make sure everything is in proper working order.

I have taken my car in twice due to my car braking when there is not a vehicle and or object in front of me but there are vehicles right behind me that have to brake but Crain denies that there are any issues. My engine light came on a couple of weeks ago and I took it to Auto Zone to have a diagnostic test done. The report states that it has something wrong with the transmission/transmission line and or fluid. When I looked it up online it stated that there are recalls on engine pistons that could cause the diagnostic test to read that it's the transmission. My car is a 2020 Hyundai Elantra value edition but according to your website, there are no recalls!?

The forward collision or emergency braking system gets activated by direct sunlight. Almost every day I drive with the sun directly in front of me in the morning and the car can activate this system with no need when going 30 to 75 mph on the 405, an extremely busy highway. There have been many almost rear ends if I wasn't able to accelerate through the braking. This is a weekly if almost daily occurrence. The independent auto shop said it can happen but they have replaced break pads twice and I'm only at 60,000 miles.

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
