Full brake failure in 7/19 and again in 10/19. We were able to avoid hitting other vehicle as little traffic. Had them completely repaired both times. 1/20 brakes failed again causing us to avoid hitting other vehicles by jumping a curb and hitting a mile marker sign a parkway. That is 3 brakes failures in 7 months. Vehicle is now totaled. This seems to be a huge issue! no injuries, thank god!.
