FORWARD COLLISION AVOIDANCE: WARNINGS

many times a year, without warning, vehicle dash lights turn off and light up like a christmas tree, followed by fca warning sound and lights going off, and a loud mechanical thud. Lose engine throttle going highway speeds. This can occur at nearly any speed without warning. Car must be powered off and back on to get normalcy. This puts me, everyone in the car and everyone on the highway at risk. Dealership was not able to reproduce or pull error codes.

Jemison, AL

LANE DEPARTURE: WARNING

Loud beep then a warning that collision warning had been disabled and the side mirrorsno longer indicated someone was beside me. . First time it's done this and I was on the way to the dealer for service. I mentioned to him and he said it was probably the light rain we had and it had blocked the camera. On the way home it did the same thing and now it was sunny, clear and they had just washed my car. So back to the dealer to have them actually check the sensor.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

UNKNOWN I was backing out of a parking space using the back up camera when I bumped a vehicle behind me. Also, when driving on the highway, the cruise control doesn't always respond properly I just want to know if my car has the latest safety updates available for insurance purposes

Dexter, MI

FORWARD COLLISION AVOIDANCE: WARNINGS

I have a 2020 Kona SE AWD and have a problem with a Check Forward Collision Sensor error that happens infrequently. When it happens, you get a ding then on the dash in a large graphic "check forward collision sensor" then BANG the brakes are applied for a split second and the car violently drops into a lower gear and revs until you turn the car off and "reset" the system. This has happened 4 times in the last 2 thousand miles. Been to the dealer twice and they cannot recreate the problem, so they can not fix anything. When this happens, its feels like a collision. It is scary and magnified at highway speed. It has happened at highway speed and low speed, both day and night.

LANE DEPARTURE: ASSIST

I was getting onto the highway the other night and all of a sudden my whole instrument panel went completely black, speed,rpm, fuel level, and water temperature were not registering on the panel. I tested my turn signals and noticed those weren’t working as well. I also lost my lane keep assist in the process. I pulled off to a safe spot turned the car off, let it sit for 5 minutes. Turned it back on and the instrument panel was still black and nothing was reading. I shut the vehicle off for 20 minutes locked/unlocked the car. Started the car back up and the instrument panel came back on but now have the check engine light on. The check engine light had never been on prior to this incident. I have reached out to Hyundai USA as well to find a solution to the issue.
