Warnings problems of the 2023 Hyundai Elantra

Electrical component with car has been malfunctioning. Adas system malfunctioning (all the lights on the dash have been coming on in and out at different times) despite turning the car on and off. Video and picture evidence has been collected on different days and times this issue has been happening. Blinkers do not work when this is happening. Concerned for safety while driving. Hyundai dealership is not helping and blowing me off.

I was driving in completely clear weather on [xxx] . No cars were within at least 100 ft in front of my vehicle. Suddenly the emergency braking system alarm flared and the brake engaged. This could have caused someone tor rear end my car but luckily no one was behind me. The brake also fairly quickly disengaged. I took it to pearson Hyundai where I had bought the car ([xxx]). They had the car for a couple of days and said they found nothing. They could not duplicate the incident. I would not have wanted to ever drive the car again as is, but the technician pointed out I could leave on the warning but eliminate the braking in settings. I am reporting this because if this happened with a child in the back seat on a road like the 95 it could do incredible harm information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Car was breaking hard because of active assist despite that no car was in front. It was breaking consistently until I finally was able to disable the active assist. Luckily, there was traffic and driving at less than 20mph but this also happened some time last year at the same area where there was no traffic and was going at a minimum speed of 45mph and to have the active assist break hard put me at great risk of getting rear ended. I have footage from the dash cam which I unfortunately cannot attach as it's more than the 10mb limit.

Since 2/2/24 13 episodes of all safety features failing including blind spot monitor, lane keep assist, forward collision warning, and others. Last occurrence on 8-8-24. On one occasion the car failed to accelerate in the middle of an intersection, the car did move slowly and operation returned to normal after turning off the car and pressing the 12v reset button. Diagnostic codes found on car app include both c164286 and c164202 for all 13 episodes. Despite being told this code is "for the speed sensor because it saw a voltage drop from the battery system" the dealer claims there is nothing they can do because they can't recreate the problem. This is highly dangerous to my family and others as the safety features can prevent accidents. The most concerning is the car suddenly losing acceleration as this could potential happen where there is no safe way to get off the road in time prior to an accident. This loss of acceleration has been reported by many other people on the facebook group I am a part of called Hyundai Elantra hybrid owners. The loss of safety features occurred after all recalls were performed as of 8-8-24.

When passing under a bridge or traveling underneath train tracks, the forward collision warning would activate causing the car to brake when no other vehicle is in front.

My 2023 Hyundai Elantra has started alerting me while driving that I was going the wrong way down a road. The alert goes something like: warning entering into wrong way detected. This occurs when I'm driving the correct direction. I've googled the issue and other Hyundai owners have documented receiving the same message. I believe this is dangerous if one is driving someplace unfamiliar and receives this message. It has the potential to alarm a driver into making a u turn and traveling into oncoming traffic.

On December 24 2023, the vehicle's forward collision warning failed. My son has a learner's permit. He was driving the car under my supervision. He pulled into a parking lot and hit a light post. We did not receive a warning, nor did the automobile automatically apply the brakes to avert the collision. There were no injuries. There was no property damage, except for our vehicle. I did not notify the police. In retrospect, we never hear alarms or warning when pulling into our narrow garage. Our other vehicles with the same safety feature do offer an alert in that context. I think the forward collision warning system is defective on this Hyundai Elantra. I have filed an insurance claim and notified the dealership by email. Next steps are pending after we hear back from our auto insurance claims adjuster.

On Saturday December 16th my vehicle was parked as I was shopping. When I returned to the vehicle and started it, lights began to light up on the dashboard. They included the rear collision, front collision, airbag, parking brake, battery, tires, blind spot, and others. I called Hyundai and they said that they did not receive any communication from the vehicle stating that there was a problem. The front and rear cameras stopped working and I could no longer tell if my turning signals were operational as I didn't hear the normal clicking sound. It was difficult to turn as the steering wheel was tight. When I first went to the dealership, they refused to take a look at the problem. After filing a complaint with Hyundai, I was finally able to take the vehicle in on yesterday. They also are confused because the initial test showed that there was no problem. They now have the vehicle and are trying to find the cause. This is very concerning because in addition to basically driving blind, according to the manufacturer book, continuing to drive with specific light on could cause engine problems. I also was no longer aware of the speed that the vehicle was traveling nor how much going. The dealership says that it will be several days before they can get to the cause. There was no warning prior to all of the lights coming on and the vehicle has not been involved in any accidents.

As I started driving my Hyundai Elantra, the digital dash and infotainment screen went black and then I got a message that my Hyundai bluelink profile along with its settings had been reset. I did not initiate this reset. I never heard anything from the manufacturer about this incident either. This momentarily caused me to lose sight of my speedometer and it reset all my adas settings such as following distances, warnings vs active assists, etc.
