Consumer Description

vehicle only has 14k miles and is showing an error message for "check forward safety system" and "check smart cruise control system" after some research found this is a very common issue with multiple Elantra's where the front radar goes bad causing safety systems such as automatic braking/acceleration, and cruise control to not work. this is a big safety issue that has been reported by many drivers. the error happened going a steady 40mph with no other cars around on an open road. nothing was hit the radar just suddenly failed
