NHTSA Complaint #11707341 — 2023 GENESIS GV70

Driving the car on 2 separate occasions in last 3 weeks when car suddenly stopped when driving and vehicle forward collision warning-braking light went on and car stopped in middle of the road and could not drive forward .The first time it lasted several minutes and then I was able to drive. Notified dealer and told it would be doubtful it could be duplicated and wash the car. The second occasion we were in the interstate highway when it suddenly stopped and forward vehicle collision warning-braking light came on.This was extremely dangerous situation being in middle lane of interstate and inching over to shoulder only with help from a car in right lane . Could not drive 3-5 feet and car would stop. Had to work way to shoulder of highway from middle lane. Called dealer for help and no return call. Went into driver's Manuel and disabled the forward collision warning system. (later told I would need to do this every time I drove)--- Dealer then evaluated and said a rock " may have hit the radar thru the grill and bent it". ( yet there was no signs of damage on grill or elsewhere)--asked to have it covered on warranty and denied , later being told that there was signs of " stress crack in lower front bumper that may have caused this. Overall unacceptable explanation and it appears to be happening to other GV70's when looking on social medial .. Was told it would cost about $2,500 to replace and not covered in warranty . This was a very dangerous occurrence while driving on the highway and could have resulted in a serious accident with nothing to warn that is might occur ( it was sudden and severe braking)
