ON JUNE 13, 2019, I HIT A ROCK IN A PARKING LOT IN THE FRONT OF THE VEHICLE. LATER TOOK TO A BODY SHOP WHEN RADAR SENSOR LIGHTS CAME ON. WAS TOLD IT WAS THE MISALLIGNMENT OF THE RADAR SENSOR UNIT CAUSED BY THE ROCK COLLISION. BODY SHOP SAYS THEY RECALIBRATED, BUT THE WARNING LIGHTS STILL RANDOMLY COME ON. COUNLDN'T GET AN APT. WITH THE DEALERSHIP TO LOOK AGAIN, FOR THE THIRD TIME, UNTIL MID SEPT. DECIDED RATHER THAN RISK A FALSE POSITIVE BREAKING SYSTEM ERROR CAUSED BY THE MALFUNCTIONING RADAR SENSOR, TO TURN IT OFF. I'M HEADING OUT ON A TRIP OVER 6 MOUNTAIN PASSES AND AM NOT PLEASED THAT I HAVE TO DO THIS AND FEEL THIS DEFECT AND LACK OF RESOLUTION FOR 3 MONTHS COULD AFFECT MY SAFETY.
