2023 Genesis GV70 Forward collision avoidance Problems

“The forward collision warning comes on and the car completely stops. We are traveling and it happened twice on busy hwy. We were not hit but came perilously close both times. We took our car in for service and asked that they disconnect this because we have had the problem before. They said they did. It has find for about 2 months and now is starting again even though it’s supposedly disconnected. There is no warning before this happens.”

“On two separate occasions over a 6 month span the emergency braking system engaged while entering an underground parking garage. There were no vehicles in front or behind. The vehicle immediately engaged the brakes forced the vehicle to stop. Fortunately there were no injuries. I have opened a case with the manufacturer. I have read on blogs that others have experienced similar ghost braking issues. In their case the manufacturer and service technician claimed since nothing was recorded by the vehicle, there was nothing to be done. …”

“After my test, here's what I found: If the cruise control is Off and you press and hold the cruise control button for more than 2 seconds, the speed limit function activates as indicated by the Limit indicator on the multi-function display. In this mode, if the vehicle speed exceeds the limit speed and you press on the gas, the power is immediately cut off, and you can't accelerate. If the vehicle exceeds the limit speed, a warning bell will sound, and the speed will flash and power is cut when pressing on the gas. …”

“Car does not detect collision, does not slow down approaching car in front during cruise control. Errors pop up daily that front radar blocked and collision avoidance is disabled. Cruise control error also pops up daily that front radar is blocked. Just got the car end of January. Had it to dealer twice. They still have it and don’t know how to fix it. It also stops all of a sudden at slow speeds when nobody is near me because it thinks a car is in front of me. Hurt my neck with this sudden stop three times. I have photos and videos of the errors Over many weeks.”

“On 3 occasions while driving under 30 mph with no proximate vehicles my car suddenly began to intermittently brake and the dash flashed collision warning . In two of them, I was able to pull over and turn off the car and restart--the problem did not repeat. In the third instance I kept driving (bucking along at 10 mph) and after about 50 yards the warning went away. The dealer ran a scan and cannot find an issue. They tell me they have to see it while it happens. The car may be at the dealer for months as they will be driving it to see if they can replicate the issue.”
