While driving on [XXX] north near exit [XXX] in rain, at 70 mph Adaptive Cruise Control and Lane Keeping Assistance were on. The vehicle displayed a warning that the smart systems were disabled. The vehicle then began jerking and changing lanes and speed unexpectedly. The steering wheel pulled/jerked forcefully to the left and right and I had difficulty maintaining control of the vehicle. When I attempted to brake, the brake pedal became very hard and could not press down the vehicle did not slow normally. I was able to get the vehicle onto the shoulder and shut it off. After restarting the vehicle, the problem occurred again. The vehicle was towed to Wallace Hyundai dealership in Stewart Florida and is currently being diagnosed. The cause has not yet been determined. Scared me to death. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

I randomly get warning lights that my camera is disabled for Lane Departure Warning, Blind Spot Warning, Forward Collision warning, Lane Assist Warning. Each warning message I get comes one after the other stating CAMERA disabled. After a few minutes of driving, all the orange lights disappear and it seems to reset itself to normal. This has happened on three random occassions. I took it immediately to Hyundai of Bay Ridge but they said they were not able to duplicate the problem. I also mentioned to them that my dashboard and Infotainment system constantly dims then brightens for no reason whatsoever. Sometimes, it dims for two seconds, then goes bright again, sometimes it dims for much longer. This happens everyday and it doesnt matter if it is a bright sunny afternoon or an early morning. It constantly dims then brightens. The dealer keeps saying they can't find anything wrong because diagnostics shows everything is ok with their computer. I feel like they are simply sweeping this under the rug because it is a leased vehicle and I am concerned for my safety should I suddenly lose power.

The “Consider Taking a Break” notification while driving is incredibly loud and distracting even when on the lowest setting and can repeat up to every 20’ while driving. While it is helpful to take a break on extended trips, it is not reasonable to stop that frequently. On long drives, this alert becomes nothing more than an irritant and distraction. There is no option to disable or silence this warning outside of turning off ALL safety notification sounds.I will probably do that just to avoid this notification, which compromises all of the other safety notification sounds that are far more important (ex. Lane departure, forward collision, and blind spot detection).

My late mother’s 2019 Hyundai Elantra (VIN: [XXX] ) was brought to Johnson Hyundai of Apex on 4/14/2025 for a known paint defect recall affecting the roof and roof rails. I was handling this vehicle as part of her estate. While the car was in the custody of their body shop, Piperformance, the windshield was cracked and replaced without my knowledge or consent. I was not informed of the damage beforehand, was never asked to authorize the repair, and was not provided an estimate or invoice in any official format. When I requested documentation, the service advisor (Josh) only sent a photo of an invoice on a laptop screen. I later received an undated, unsigned letter from the body shop admitting that they had broken the windshield and kept the old one. Important inspection and registration stickers were removed during the process and not returned for weeks. Hyundai corporate acknowledged internal failures, including missing documentation, conflicting stories, and lack of accountability. However, they refused to accept responsibility or confirm what safety inspections, if any, were done after the unauthorized windshield replacement. I am concerned the windshield replacement may not meet OEM specifications and may compromise the vehicle’s crash safety or ADAS systems (lane keeping, forward collision alert, etc.). No documentation was provided to show the glass used was certified or that proper recalibrations were performed. I no longer trust the safety of this vehicle and plan to remove it from use. The emotional toll of dealing with this after my mother’s passing makes the experience even more distressing. Her car was defaced and mishandled in my effort to preserve it, and I now feel responsible for navigating safety concerns caused by others’ negligence.
