2021 Hyundai Elantra VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE

One day I was on the highway driving and the front collusion safety warning appeared. I thought the warning went off because the sensor was dirty due to dead bugs. However, I pulled over and the sensor did not appear dirty. After awhile the sensor went off on its own. Then a few weeks late the front collusion safety warning appeared again while I was driving on the highway. The warning has not fixed itself. I cannot use my cruise control. I took it to the Hyundai dealership and they told the me senor is off alignment and it will cost $500 to repair because they have to remove the entire bumper. I have seen on Hyundai forums this is a common problem.

Driving on highway, dashboard reported "Check Forward Safety System" and "Check Smart Cruise Control System". The car then disabled both while I was driving. This has happened 6 times to me. The first time I brought it to dealer and they stated it was a calibration problem. They reset it and I had no problems for a while. The problem has occurred 5 times more and will stay on for about a week or so and then just go away. It works again and then occurs again. So, it is intermittent and recurring. Each time the diagnostic code reported by the software to my phone is C162078. I see the 2018 Kona had the same exact problem and a software update TSB was put out there.

The forward collision warning stopped working several months ago. We gave the (leased) car to the dealer for repairs after 4 weeks of waiting (parts, etc.) We were told the car was fixed and ready for pick-up. I drove it from Baltimore to DC for a meeting and on several occassions when car stopped abruptly in front of me on the highway it did not give a warning, when I tried using cruise control, it would not engage because the conditions for doing so had not been met - same message I had when foward collision was not working. It's pretty clear that this was not fixed and instead they must have changed the messaging so that it does not appear as a warning when you start the car. The feature is really important to us because it has prevented a potentially fatal accident on a winding road in NY state where we found a truck on our lane due to a downed tree on the other lane - the car braked well before I did- which is the point of these safety systems. The dealer is Len Stoler Hyundai in Owings Mills

Check forward safety system is on all the time, dealer refusing to fix it. Did have airbag recall repai done yesterday Had computer update done on car.

Forward collision system continually fails. This disables the vehicles cruise control. The vehicle has been in the shop multiple times with no resolution.
