NHTSA Complaint #11139433 — 2018 CHEVROLET IMPALA

THE FORWARD COLLISION ALERT SYSTEM WHICH IS STATED TO WORK OVER 40 MPH DOES NOT GIVE ADEQUATE WARNING AT ANY SETTING. THE SYSTEM SHOWS A GREEN ICON WHEN FOLLOWING ANOTHER VEHICLE. THE ICON CHANGES TO AMBER WHEN FOLLOWING ANOTHER VEHICLE EXTREMELY CLOSE (WAY TOO CLOSE) AS A TAILGATING ALERT. IT IS MEANT TO GIVE A HEADS UPS FLASHING RED DISPLAY ON THE WINDSHIELD WHEN OVERTAKING ANOTHER VEHICLE AT A SPEED THAT MAY CAUSE A COLLISION. THIS SYSTEM HAS A NEAR. A MEDIUM AND A FAR SETTING WHICH IS SUPPOSED TO FUNCTION WITHIN 194 FT. AT NO SETTING APPROACHING A VEHICLE FROM THE REAR TO A DANGEROUSLY CLOSE POINT COULD I GET THE SYSTEM TO GIVE A RED ALERT, THIS WAS ON THE FAR SETTING. THE DEALER SERVICE CHECKED THE SYSTEM IN THE GARAGE AND SAID IT WAS WORKING. THEY WOULD NOT DO A ROAD CHECK BECAUSE IT IS TOO DANGEROUS. THE SERVICE MANAGER SAID HE HAD DONE THEM IN THE PAST AND THE RED ALERT ONLY HAPPENS WHEN YOU ARE EXTREMELY CLOSE TO THE CAR AHEAD. IN A CONTROLLED CHECK I GOT TO WITHIN A CARS LENGTH OVERTAKING THE CAR AHEAD WITH NO ALERT AND THIS WAS ON THE FAR SETTING. THIS SYSTEM IS USELESS WITHOUT GIVING AN ALERT IN TIME TO REACT. I HAVE SEEN THIS SYSTEM WORK WELL IN OTHER BRAND CARS.
