Complaint Summary

VEHICLE SPEED CONTROL

Owner Narrative

THE PROBLEM IS CENTERED AROUND ADAPTIVE CRUISE CONTROL SYSTEM OF BMW 740I 2016. BMW 740I CAN'T DETECT VEHICLES FROM THE RIGHT CORNER OR LEFT CORNER WHEN TWO LANES MERGE INTO ONE AND THE BMW IS APPROACHING THE OTHER VEHICLE WHERE THE OTHER VEHICLE IS EITHER AT FRONT RIGHT OR LEFT RIGHT. THERE ARE MULTIPLE SYMPTOMS OF THIS PROBLEM: FIRST SYMPTOM, BMW 740I IS NOT TRACKING ANY VEHICLE AND COCKPIT DOES NOT SHOW A TRACKED VEHICLE. A CAR OR BIG TRUCK IS IN THE SECOND LANE MERGING FROM EITHER CORNER, BMW 740I DOES NOT DETECT THOUGH THERE WAS ENOUGH TIME AND DISTANCE TO DETECT. IN ONE EXAMPLE THERE WAS 18 WHEELER MERGING LANE AND BMW NEVER DETECTED THE 18 WHEELER THOUGH MAJORITY OF THE 18 WHEELER WAS AHEAD OF THE BMW FROM THE RIGHT CORNER. SECOND SYMPTOM IS BMW 740I IS TRACKING ANOTHER VEHICLE, WHEN TWO LANES MERGE THERE IS A CAR FROM THE OTHER LANE COMING IN FRONT FROM THE RIGHT CORNER OR LEFT CORNER, BMW NEVER SLOWS DOWN FURTHER SINCE THAT VEHICLE IS ALREADY NOW IN VIEW OF THE BMW. MY UNDERSTANDING THE BMW USES THE CAMERA BEHIND THE REAR VIEW MIRROR, FACING FORWARD, TO DETECT SUCH SCENARIOS.
