2012 ACURA MDX Vehicle Speed Control Problems

WHEN DRIVING USING ACC, THE VEHICLE BRAKES (NOT CONSISTENTLY) WHEN APPROACHING A LARGE TRUCK IN THE LANE NEXT TO LANE I AM DRIVING IN. THIS HAS HAPPENED SINCE NEW AND HAS BEEN REPORTED AT LEAST 10 TIMES TO DEALER AND THEY SAY THEY CAN'T REPRODUCE THE ISSUE. GAS MILEAGE IS 12MPG IN TOWN AND 19MPG ON FREEWAY, STICKER WAS 16/23. I HAVE COMPLAINED ABOUT THIS SINCE NEW AND THEY DRIVE THE CAR AND SAY THEY ARE GETTING CORRECT MILEAGE, THEN THEY TOLD ME THE BRAKES NEEDED TO BE REPLACED AND THE ROTORS NEEDED GRINDING. I WAS ASSURED BY THE SERVICE WRITER THAT MY MILEAGE WOULD BE MUCH BETTER, WITH A WINK OF AN EYE. I LEFT THE NEXT DAY FOR 600 MILE DRIVE AND MY MILEAGE WAS 20MGP IN TOWN AND 27MPG ON FREEWAY, THIS LASTED FOR ABOUT TWO MONTHS. TEMPERATURE GUAGE FOR OUTSIDE TEMP HAS NEVER WORKED. ON HOT...

THE VEHICLE WAS TAKEN TO THE DEALER ON MULTIPLE OCCASIONS BUT THE CAUSE OF THE FAILURE WAS NOT DETERMINED AND THE CONTACT WAS INFORMED THAT THE VEHICLE WAS OPERATING NORMALLY. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 2,000.
