2023 Hyundai Elantra Lane Departure Problems

Your car's lane departure warning system may not be working correctly. The complaint involves a crash, so this appears to be a safety system failure that could affect your vehicle's ability to alert you when drifting out of your lane.

The vehicle applies automatic emergency brakes when another vehicle passes close by from behind in an adjacent lane, when the Blind Spot Collision Avoidance Assist, feature is set to “Active Assist.” The owner’s manual states that this feature operates when the turn signal is turned on in the direction of the detected vehicle. However, my experience shows that the car applies brakes even when the turn signal is off and the vehicle is driving straight within its lane, without changing lanes. As per NHTSA description automatic breaks to be applied if the driver ignores the warning and tries to change the lane. But Hyundai design applies brakes even if car driven within lane without any warning before applying break

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.
